INTRODUCTION

The organic farming system (similar to „biologic” or „ecologic” terms) is a “modern” plant growing, animal breeding and food processing system fundamentally different from the conventional farming system. The role of the organic farming system is to enhance the „clean” food production, more adequate to human methabolism, in compliance with the environment preservation issue and full respect for nature. The organic farming system contributes to the added value economic activities development and to the interest for rural areas growing.

From both objective and subjective reasons, wheat cultivation in the past few years in Romania is declining. This situation demands a serious economic efficiency analysis and a strategy to increase wheat cultivation profitability.

One prior condition for high and stable yields is the choice of the most suitable wheat variety in compliance to the region’s climate and soil particularities. Beyond the high yield potential, the chosen varieties have to be resistant to main stress factors and must have grain high quality potential.

Cultivated grains have to give satisfactory results in quantity and quality. Nowadays the quantity is overwhelmed by the quality issue. Consumers are more and more oriented to buy healthy food, and they are awared that healthy food is produced mainly in organic farming system.

Obviously, the yields level depends on the cultural methods, starting with the varieties choise and ending with the harvesting issue. The most suitable variety choise can not guarantee by itself good yields if the wide range of technological works are not properly applied. In the nowadays wheat technology the foundation for high yields starts from the crop settlement which consists of several technological sequences ment to lead to well developed crop fields.

In the nowadays social, economic and ecologic framework, worldwide, there is a general trend to swich from the conventional industrial, intensive farming system to organic farming, a „common sense” farming system which has to comply to the following major objectives:

- producing enough quantity, high quality and with reasonable costs food stuffs; - improving and preserving the natural environment and reducing the

pollution sources; - establishing the framework for food processors to supply the mankind with

healthy food, to guarantee the environment security, to enable increase of incomes, to give satisfaction of the workers and to create a balance in the man-nature harmony.

I express my deepest gratitude and consideration to. Mr. Professor LEON SORIN MUNTEAN, scientific coordinator of this Doctoral thesis, for the great honour he granted by accepting me in the group of PhD students and for his entire support from the first experimental protocol untill the fulfilment of the research work and written material.

I want to express also my sincerely gratitude to the Board of the University of Agricultural Sciences and Veterinary Medicine from Cluj-Napoca and especially to the Board of the Faculty of Agriculture for the overall outstanding research conditions. Special gratitude to the whole team from the Phytotechny Department for the granted support.

Ţandrău Nicolae, general manager of Minexfor Gmbh Deva and to Mr. Christian Haeni for the granted support in organizing and fullfilling the research in the experimental fields from Chimindia (Hunedoara county) and Fireteaz (Arad county).

Also, I experess special thanks to Dr. Vasile Moldovan and Dr. Rozalia Kadar , from the Agricultural Research and Development Station Turda for their valuable suggestions according to documentation and relization of final form of the thesis.

And I adress my deepest gratitude to my family members for their unconditionned generosity and moral support.

CHAPTER 1 THE ORGANIC FARMING SYSTEM WORLD WIDE

AND IN ROMANIA

1.1. THE ORGANIC FARMING SYSTEM WORLDWIDE

The modern organic farming system hystory begins at the end of the previous century, when some illuminates people, mainly from Germany, have started to analyse the gap between mankind and nature and tried to give sollutions to end this situation.

In this framework, Rudolf Steiner, a phylosophus born in Austria, professor and founder of anthroposofy, set up in 1924 a new farming concept where the farm was treated as a selfsupporting system.

One of his students, Ehrenfried Pfeiffer, has developed this theory and named it „the biodinamic farming system”. The main principles which were driving this type of thinking were as following: to apply rational cultural techniques, no matter if classic or new ornes, which to comply to “the Steiner methamorphosys” – plant, animal, humans – everything being related to air, water and soil and driven by a spiritual force; to promote new principles such as diversity preservation (diversity and biodiversity); to enhance the chemical elements and substance recycling, to hinder the polluant substances spread and to promote the new agriculture schools knowledge and knowhow; development of enable research and discovery of new biodynamic concepts and methods.

In fact, the organic farming system has been developed at the end of 1970’s together with the growing influence of the „green” movements, when both farmers and consumers started to be concerned by the environmental issues. The movement has started in the northern european countries (Denmark, Germany, The Nederlands) and then has spreaded to Mediteranean countris (France, Italy, Greece) and USA. Thus there have been established the first organic farmers associations.

The countries with the largest organic management acreage worldwide are: Australia (11,8 million ha), Argentina (3,1 million ha), China (2,3 million ha) and U.S.A. (1,6 million ha). However, the number of organic farmers and the share between organic and conventional farming systems are best represented in Europe. There has been noticed a spectacular growth in organic-farming acreage in the North America and Europe of more than half million hectares, compared to the 2004 status. In most countries around the globe organic farming is showing an uptrend, but there are also some downtrend countries, such as: China, Chile and Australia (SOEL-FiBL 2007).

1.2. ORGANIC FARMING SYSTEM IN ROMANIA

The organic farming system relies, on one hand, on human willing to comply the natural environment rules, and on the other hand, on the imperative of saving the human habitats, where the soil fertility and biodiversity are basic components which have to be preserved and improved.

In Romania, the organic farmland share has increased more than six times in the last five years, from 17,438 ha in 2000 to 110,400 ha in 2005 and 143,000 ha in 2006. It has been foreseen a growth in organic acreage of 1.7% in 2007, to about 250,000 ha, and of 2.72% untill 2010 (up to 400,000 ha).(Source: M.A.R.D. Communications of inspection and certification bodies).

The wheat yield harvested untill the 22nd of august was of only 3 milion to in 2007, with 44% lower than the 2006 yield (5.4 milion to). (Source: National of Statistics Institute)

From many points of wiew, the organic farming in Romania is at the first steps. More developed is the conceptual issue, as an result of experience gained after 16 yeard of theoretical and applied studies and researches and of steady promotion by several NGO’s such as: The Romanian Association for Sustenable Agriculture, The Romanian Organic Farmers Association „BIOTERRA”, The ”AGROECOLOGIA” Association.

Taking into consideration that organic farming can give solutions to solve the small size household farms problems (land crumbling, decline in farmers number and physical condition / farmers aging, rudimentary technology, subsistance management) and knowing that Romania’s potential for organic land management is about 25% of the total farmland, the organic farming system development has to become a state policy (Toncea, 2000).

CHAPTER 2

THE RESEARCH CURRENT STATUS ON WHEAT AND RYE

CULTIVATION IN ORGANIC FARMING SYSTEM

Wheat cultivation worldwide Among the factors which are enabling the wheat cultivation spread wordwide

we note the climate conditions, the soil quality and the economic framework. The most suitable regions for wheat cultivation are the temperate areas in the north and south from Ecuator. In theese areas it’s concentrated the worlds’ most impoprtant wheat acreage and here there are registered the highest yields.The most suitable regions for wheat cultivation are those where there are enough rain falls during crops brotherhood, spire and earing stages. The light period, intensity and spectrum, determine the wheat distribution around the globe. (Muntean, and colab.,2003)

CHAPTER 5

RESULTS REGARDING THE PHENOLOGICAL DATA. THE VEGETATION CYCLE

In the grown season 2006-2007 at the both experimental fields Chimindia

and Fireteaz, the wheat and rye growth stage have been developed in the drought conditions, with 368 mm rainfall ( Chimindia ) and respectivelly 268 mm ( Fireteaz). The most affected by the dry conditions was GK Kalasz variety which react by delayed of each growth stage. Ariesan variety had o good behaviour in the same condition. The spelta variety Franckenkorn which later with 11 days in maturity, comparatively with the others.

46  

The grown season 2007-2008 have been characterized by normal rainfall conditions which ashured good watter suplies for all critical growth stages.

Finaly in the grown season 2008-2009, those four varieties showed their particularity according to development stage.

CHAPTER 6

RESULTS REGARDING THE WEEDS INCIDENCE There are 17 varieties of dicotiledonates weeds occuring in the crop fields,

out of which 12 anual varieties and 5 perennial varieties. In the 2007 - 2009 farming seasons climate conditions the weed varieties number and incidence is fluctuating depending on the variant and field location. The prevailfog weed varieties observed were the perennial dicotiledonates (Convolvulus arvensis, Cirsium arvense, Sonchus arvensis and Equisetum arvense).

RESULTS REGARDING THE YIELDS

8.1.4 Average winter wheat yields on Chimindia experimental field (2007-2009) Average winter wheat yields range between 2100 kg/ha and 5034 kg/ha. The

factors influence was detected every year. Average yields analysis for the four studied varieties (table 8.13) shows the

highest yields for Arieşan variety (4038,65 kg/ha) and Betadur variety (3234,76 kg/ha) with very significant and respectively distinguished significant differences. In the Frankencorn variety case the differences are very significant negative (-485,16 kg/ha). Variants comparision (table 8.13) regarding the variety factor influence, through the Duncan test tool is ranking the yields as following: Frankencorn variety (A), Kalasz variety (B), Betadur variety (C) and Arieşan variety (D).

been obtained high yields with very significant differences; the plus in the yields level was inbetween 7,3 and 24,9% according to the fertilization scheme (table 8.30). Duncan test data processing tool is ranking the fertilization variants as following: on soil + in green fertilization II (E – 3765,83 kg/ha), on soil + in green fertilization I (D – 3642,67 kg/ha), in green fertilization (C – 3437,33 kg/ha) and on soil fertilization (B -3236,00 kg/

CHAPTER 10 CONCLUSIONS AND RECOMMANDATIONS

CONCLUSIONS

10.1. THE PLANTS NUMBER IN WINTER INGRESS AND EGRESS

In the 2006-2007 farming season on Chimindia experimental field, the biggest wheat plants number in winter ingress was obtained by Ariesan variety (379 plants/sqm), followed by Betadur and Kalasz varieties, and the lowest wheat plants number was obtained by Franckenkorn variety (208 plants/sqm), and for Fireteaz experimental field, the biggest wheat plants number in winter ingress was obtained by Ariesan variety (398 plants/sqm), followed by Betadur and Kalasz varieties, and the lowest wheat plants number was obtained by Franckenkorn variety (212 plants/sqm).

As regarding the 2007-2008 farming season, on Chimindia experimental field, the biggest wheat plants number in winter ingress was obtained by Ariesan variety (458 plants/sqm), followed by Betadur and Kalasz varieties, and the lowest wheat plants number was obtained by Spelta variety (333 plants/sqm), and for Fireteaz experimental field, the biggest wheat plants number in winter ingress was obtained by Ariesan variety (475 plants/sqm), followed by Betadur and Kalasz varieties, and the lowest wheat plants number was obtained by Franckenkorn variety (321 plants/sqm).

In the 2008-2009 farming season, on Chimindia experimental field, the biggest wheat plants number in winter ingress was obtained by Ariesan variety (458 plants/sqm), followed by Betadur and Kalasz varieties, and the lowest wheat plants number was obtained by Franckenkorn variety (333 plants/sqm), respectively in Fireteaz experimental field, the biggest wheat plants number in winter ingress was obtained by Ariesan variety (467 plants/sqm), followed by Betadur and Kalasz

Page 25: SUMMARY OF PhD THESIS RESEARCH ON ORGANIC WINTER …SUMMARY OF PhD THESIS RESEARCH ON ORGANIC WINTER WHEAT ... In this framework, Rudolf Steiner, a phylosophus born in Austria, professor

62  

varieties, and the lowest wheat plants number was obtained by Franckenkorn variety (324 plants/sqm).

The 3 years data obtained reveal that the highest wheat plants number in winter ingress was obtained by Ariesan and Betadur varieties and smaller figures for Kalasz and Franckenkorn varieties.

As regarding the difference between wheat plants number in winter ingress and egress, based on experimental data obtained, we can state that Ariesan and Franckenkorn varieties are more resistant than Betadur and Kalasz varieties to winter climate conditions.

The rye variety, in the experimental field Chimindia had a good germination. Number of plants in autumn was 433 /m2 in the variants soil+in green fertilization, respectively 394/m2 on the unfertilized variant.

In the experimental field fireateaz,rye had also a good germination, the number of plants being 431/m2 in the variant soil+in green fertilization and 388/m2 on unfertilized variant.

10.2. PHENOLOGICAL DATA

In the 2006-2007 farming season, in both experimental fields (Chimindia and Fireteaz), plants were growing in drought conditions (376 mm rain falls in Chimindia experimental field and 268 mm in Fireteaz experimental field) compared to minimum stated by many years experience. The most affected by dryness was Kalasz variety, thus it passed through each vegetation stage with a time lag. The inconvennient was diminished by the gentle winter conditions with moderate temperature. Ariesan variety has had the best behaviour. Franckenkorn (Spelta) is the most belated variety, delayed with 11 days. However, as being an extensive variety, Spelta has managed to rank the same place with Kalasz variety (an intensive variety) in that season.

The 2007-2008 farming season can be defined as an optimum rain falls year, mainly in the critical plants growing stages, thus the plants evolution was normal.

In 2008-2009 farming season, generaly speaking, as regarding the vegetation cycle period and caracteristics, the four wheat varieties have totaly proved their peculiar genotyphic features.

Rye is earlier than winter what, so in 20 june all the phenophases are passing, when the rye can be harverst.

The period of vegetation, in the year 2006-2007 was 251 days on Chimindia and 244 days on Fireteaz.

10.3. WEED INCIDENCE

In the first experimental year (the 2006-2007 farming season) it was impossible to appreciate if the cultivated variety has a significant influence on weed incidence, differences could result also from other factors influence. This farming seasons’ conclusion was that the perenial dicotiledonates group (including Equisetum arvense) could make problems for the organic wheat growers in this area due to the soil biologic potential, the specific climate conditions and the vegetation features of weeds in this group.

Overall wheat plots analysis shows that organic winter wheat cultivation have to be done with the help of biofertilizers, which have a positive influence on crop behaviour, including weed incidence decrease.

In the 2007-2008 and 2008-2009 farming seasons it was prooved that the cultivated variety can significantly influence the weed incidence. Thus, Ariesan variety was the best in the weed competition, followed by Betadur variety, while Franckenkorn (Spelta) variety has been the most susceptible to the specific weed incidence risk.

From the 3 years average data it was confirmed the hypothesis that biofertilizers usage in organic farming is leading to weed incidence decrease, the downtrend in weed number being very significant in all fertilization variants.

The weed problem is Cirsum arvense,which apear with a frequency under economic level of damages. This situation can be attribute to the fact taht winter wheat and rye follow in the crop season after pea+oat.

10.4. OUTPUT COEFICIENTS AND QUALITY PARAMETERS

The yields data for 2006-2007 farming season, on Chimindia experimental field, lead us to state that Ariesan variety has obtained the best yield (3900 kg/ha), followed by Kalasz variety (3300 kg/ha), Betadur variety (3233 kg/ha) and Franckenkorn variety (2800 kg/ha). In Fireteaz experimental field, Ariesan variety has realized the best yield (4033 kg/ha), followed by Kalasz variety (3400 kg/ha), Betadur variety (3333 kg/ha) and Franckenkorn variety (2867 kg/ha).

For the next farming season (2007-2008) in Chimindia experimental field it was revealed again the best yield for Ariesan variety (5034 kg/ha), followed by Betadur variety (4033 kg/ha), Kalasz variety (3967 kg/ha) and Franckenkorn variety (3300 kg/ha). In Fireteaz experimental field there were obtained the following yield levels: Ariesan variety (5167 kg/ha), Betadur variety (4134 kg/ha), Kalasz variety (4034 kg/ha) and Franckenkorn variety (3433 kg/ha).

The fertilized variants have revealed the highest yields, no matter the wheat variety and the experimental field location.

The results regarding the grain quality parameters show very good results for the weight test, gluten content, hardness and protein content for Franckenkorn variety, followed by Ariesan, Betadur and Kalasz varieties. The grain moisture content is lower than 14% for all the studied varieties.

10.5. YIELDS

As refering to the fertilization variant influence on yields, there have been registered higher yields and a positive significant difference compared to the witness for all the studied varieties and fertilization schemes.

The Duncan test data processing ranks the variants in the following range: Ariesan variety – on soil + in green fertilization (II); Betadur variety - on soil + in green fertilization (I); Kalasz variety - on soil + in green fertilization (II); Franckenkorn variety - on soil + in green fertilization (I); a.s.o.

The variety interraction on fertilization scheme is much more diversified as influence on the obtained yields and shows the overall superiority of Ariesan and Betadur varieties.

The rye variety Suceveana respond very well on fertilization, with a plus of yield ( >1000 kg/ha ) .in the experimental field Fireteaz was obtained lower yiels than in Chimindia location, but the fertilization is also important here.

The influence of fertilization is important on rye yield, so Suceveana variety has a positive reaction to this factor. All variants of fertilization given significant difference of yield as compared with check variant.

10.6. ECONOMIC PERFORMANCE

Speaking of economic performance, in 2006-2007 farming season, Ariesan variety has won the first place by overtaking its own witness with more than 25%, which means that it answers very good to fertilization and nursing works. At the same time, Ariesan variety has registered the best gross margin (+64% compared to its own witness), followed by Kalasz, Spelta and Betadur varieties. As regarding the expenditures, these are higher in the fertilized variants case, in average by 12% compared to the witness.

The situation changes if we compare the revenue on acreage unit. Thus, Spelta variety, with a higher market price (+42% compared to other wheat varieties) brings an extra income of 37-45% compared to Kalasz and Betadur varieties.

Spelta variety, even in unfavourable climate conditions, like the 2006-2007 farming season, has a satisfactory behaviour and gives secure yields and economic advantage. If we consider the high probability of repeated unfavourable seasons, the variety selection must be done according to this fact.

Spelta variety has registered the highest profit not because of the best yield, but due to the higher market price (double compared to other wheat varieties). This variety could be always sold at double price (1,5 lei/kg compared to 0,9 lei/kg – the autumn 2008 market price). That’s why farmers should take into consideration to introduce this variety in organic cultivation.

In the above mentioned market conditions, although Ariesan variety obtains the best yields, its profit is with 58% lower than for Spelta variety.

The yield obtained by rye variety Suceveana under organic farmic at Chimindia was 4300 kg/ha in variant of fertilization on soil + in green and only 3548 kg/ha in unfertilizated variant. The market price of rye product ( grain ) in average in three years was 0.83 lei/kg, which result in an profit of 2239 lei/ha ( fertilized variant ) in comparison with 1805 lei/ha ( ufertilized variant ).

RECOMMENDATIONS

1. Choice of the most suitable varieties for organic cultivation

In organic farming, due to the peculiar technological features of this agricultural system, the basic criteria in choosing the varieties for cultivation must be related to: pests and deseases resistance, drought and other stress factors resistance.

For organic cultivation, in hilly and mountaneous regions, we recommand the Franckenkorn and Arieşan winter wheat varieties. Kalasz variety, although being a high value variety, has proved an unconvincing behaviour in drought conditions.

Spelta variety is recommanded at least for two reasons: good resistance to extreme temperatures and drought conditions and the highest revenue (+50-70% compared to the other varieties).

2. The correct organic farming agrotechnical works application In organic farming, because of just a few methods to control the limitative

cultural factors, besides the suitable varieties choice, application of specific agrotechnical methods is strictly necessary.

The optimum moment for mechanical works and the use of the most suitable equipment is the guarantee of the main objectives fulfilment. Climate conditions, especially the rain falls in the planting season, are endengering the germinating layer preparation. The irregular plants emergence has a bad influence on the yields obtained.

From the studied winter wheat varieties, Ariesan variety has had the best behaviour to humidity absence and unsufficient soil works, while Spelta variety has been the most affected by the same unfavourable conditions.

It is better to wait for the optim moment to do the seed bed works than to follow the optimum seeding period, no matter what.

For the weed contol the agrotechnical works have a great importance. The weed curry can solve the weed problem up to 90%. We underline the great importance of the right choice of the nursing works period and it’s very important that the working machine to be adjusted in accordance with the soil moisture content and the phenological wheat plant stage.

It has been proved that biofertilizers use has a positive impact on weed incidence as well as on the wheat crop growing. The most efficient fertilization system for all the studied wheat varieties was the on soil + in green fertilization scheme.
