1. Background information

Maize is the 2nd

most important lifesaving crops of the country with the potentiality of

highest productivity per unit area. It is the food for more than 14 million people in the hills

and playing a vital role in the livelihood of rural people in Nepal. The average nationalproductivity of maize in Nepal is 2119 kg/ha (MoAC, 2009/10) which is very low compared

to maize productivity in India and China, the neighboring countries. Mid hill region is themost important corn belt of the country where more than 70% maize area of the country is

situated (MoAC 2009/10).

The exponential growth of the human population and change of food habit in the recent

years, people are consuming more milk, meat, fish and eggs because of increasing trends of

income every year. The increased demand of those items needs more maize grains for

poultry and animals feeds. Maize can be used as food, feed, fodder, fuel and raw materials

for various industrial purposes. Maize is the main ingredient for poultry and animal feeds.

The annual growth rate of demand for feed will be 3.38 per cent per annum for 2001 to

2010. Meanwhile, imports of maize seeds have also risen. Maize seed imports soared to

9,778 tons in 2009-10 from 458 tons during the previous fiscal year (NMRP, 2011). Maize

growing farmers have not faced any problems of selling maize grains in Nepal.

Increment in the production and productivity of maize in the country is extremely essentialwhich is possible only by developing and promoting new and improved high yielding maize

varieties. The proposed varieties namely Arun-4, Arun-3 and Karnali-2 are of broad geneticbased having good yield potential. Stakeholders preferred these varieties due to higher grain

yield, non-lodging and moderately resistant to weevil and stem borer. It is equally good forintercropping and green ear roasting. The mean grain yield of Arun-4, Arun-3 and Pool-17 E

varieties were tested by majority of marginalized and socially disadvantaged groups of

farmers (Dalit and women) and they expressed their desire to plant these varieties in thecoming years.

Existing varietal options to the farmers is very low and varietal replacement rate of the

country is also poor. Seven released maize varieties have been denotified out of the total

twenty three released varieties in the country. In this context, we should provide more

varietal selection options to the maize farmers to enhance the productivity of maize in terai

and hills. The newly proposed three maize varieties namely Arun-4, Arun-3 and Karnali-2

could be able to provide immediate varietal selection options to the farmers. Since these

varieties are early in maturity days, they fit in rice-wheat-maize cropping system and

vegetables can be grown after harvesting them. Keeping all these in consideration, NMRP

has proposed three new maize varieties namely Arun-4, Arun-3 and Karnali-2.

Draft copy

3.2.1 Biotic stresses(a) Insects: Specific problems related to insects have not been identified. It is apparent

from the results that all Arun-4, Arun-1EV and Pool-17 E showed minimum

infestation of maize stem borer. Weevil infestation during storage is not a problem

since the husk cover is tight.(b)Diseases: Arun-4, Arun-1EV and Pool-17 E has shown resistant to moderately

resistant reaction against leaf blight diseases (Northern leaf blight, Southern leaf

blight and Banded leaf and sheath blight (BLSB) in natural condition (Annexure 29and 30), though its inbred exhibited moderately susceptible reaction agains t NLB

under artificially inoculated condition (Annexure 4 and 30).

(c)Weeds: No specific association of weeds with this variety and does not require anyspecial care for weed management. However, the field should be free from weed to

attain higher grain yield and crop management practices applied to other maize

hybrids or OPVs is also sufficient for this variety.

3.2.2 Abiotic stresses(a) Adverse climatic conditions: These varieties were evaluated under heat screeningnursery at NMRP, Rampur; RARS, Parwanipur; and RARS, Tarahara in summerseason of 2010 (Annex 20). The results showed that it prefer favorable

environment rather than heat stress condition for higher yield performance. Thecrop could not perform well under any type of stress condition such as water

stagnation, drought, heat and cold stresses. The genotypes can flourish its

potentiality under optimum condition.

(b) Adverse soil conditions: The crop prefers loam to sandy loam soil for better yield

performance. It requires frequent irrigation and heavy dose of manure and

fertilizer than OPVs to obtain expected yield.

(c ) Other stresses, if any:

4.2. Molecular characteristics (Not available)

5. Recommendation domain:

5.1Geographical area (altitude, latitude and longitude): Arun-4 and Arun-1EV were testedat many locations from east to mid-western terai in the various experimental trials CVT

and FFT (Table 1). Therefore, this variety is proposed to recommend for commercial

cultivation from east terai to mid-western Terai, inner Terai and mid hills of Nepal. 5.2Moisture regime: partially irrigated and irrigated. Soil moisture as well atmospheric

moisture is critical at 7 days before and after flowering.

5.3Climatic conditions: If the atmospheric temperature rises more than 38oc pollen grainsstart to die by appearing tassel firing symptoms and atmospheric temperature below 8

oC

is not also suitable during flowering time.

5.4Cropping pattern:The variety is suitable under both maize and rice based cropping system. However,

higher level of production can be obtained when the crop is grown in winter rather than

summer planting.

a. Maize based cropping system:Maize-Soybean-VegetablesMaize-Rajma-Vegetables

Maize-Sesame-Maize

Maize-Black gram-tori etc.

b. Rice based cropping system:Rice-Maize-Mungbean

Rice-Maize-Cowpea

Rice-Maize-Vegetables

Rice-Wheat-Maize

Maize-Maize-Rice etc.5.5Socioeconomic conditions: The farmers who are growing maize in terai and inner terai

condition can easily grow this variety. Farmers can use as fodder after harvesting andget more benefits from this variety than others from milk and milk products. So, the

variety is friendly even to resource poor farmers, who can get higher yield per unit area.

5.6Economic analysis and benefit:Arun-4:

The improved genotype Arun-4 yielded 12.35 % more grain yield than the local check when

averaged over seven years data from CFFT over the locations. The average yield of seven

years (2001-2010) of Arun-4 was recorded 4436 kg/ha whereas local check was recorded at

the same period 3888 kg/ha. The difference between this improved one and local check atthe farmers field was 548 kg/ha which amounts Rs 9316 if sold for grain @ Rs 17/kg


9/27

Draft copy

whereas the same quantity if sold as seed @ Rs 40/kg then, the amount will be of Rs21920/- which is extra benefit by growing this genotype. Under intercropped with soybean,

Arun-4 produced net income of NRs. 43228/- per hectare (NMRP, 2009)

Arun 1 EV:

The improved genotype Arun-1 EV yielded 3.80 % more grain yield than the local checkwhen averaged over seven years data from CFFT over the locations. The average yield of

seven years (20001-2010) of Arun-1EV was recorded 4042 kg/ha whereas local check was

recorded at the same period 3888 kg/ha. The difference between this improved one and localcheck at the farmers field was 154 kg/ha which amounts Rs 2618/- if sold for grain @ Rs

17/- whereas the same quantity if sold as seed @ Rs 40/kg then, the amount will be of Rs

6160/-, which is extra benefit by growing this genotype. Under intercropped with soybean,

Arun-1 EV produced net income of NRs. 36640/- per hectare (NMRP, 2009)

Pool-17 E:The improved genotype Pool-17 E yielded 9.36 % less grain yield than the local check when

averaged over seven years data from CFFT over the locations. The average yield of sevenyears (20001-2010) of Pool-17 E was recorded 3555 kg/ha whereas local check was

recorded at the same period 3888 kg/ha. The difference between local check and thisimproved one at the farmers field was 333 kg/ha which amounts Rs 5661/ - if sold for grain

@ Rs 17/- whereas the same quantity if sold as seed @ Rs 40/kg then, the amount will be ofRs 13320, which is extra loss by growing this genotype. However under intercropped with

soybean, Arun-1 EV produced net income of NRs. 13008/- per hectare (NMRP, 2009).

6 Production and management aspect (Please add detailed information, if necessary, onthe general cultivation practices; appropriate input and moisture regimes): Package of

practice is similar to the Arun-2, released in 1982 and other maize varieties which are

growing by farmers in maize growing districts.

6.1Agronomic Practices: 2-3 ploughings are needed for land preparation. First ploughing should be carried out

30 days prior to maize sowing.

The main season for planting these varieties are summer season however it can begrown in winter and spring season.

The recommended dose of fertilizer 120:60:40 N:P2O5:K2O kg ha-1 along with 10-15 tons of farm yard manure.. FYM and full dose of P205 and K20 along with 50%

nitrogen should be applied during last ploughing (before crop sowing). 25% Urea

should be top-dressed during knee high stage and 25% just prior to tasseling andsilking.

Seed rate 25 kg ha-1 for general grain production. The recommended planting space for early variety is : Row-to-Row distance:

75 cm

Plant to plant distance: 25 cmWeeding: First weeding should be done within 20-25 days and second weeding (earthing

up) within 40-45 days after the germination. Priority should be given to manual weeding.However, Glyphosate @ 5ml/litre as pre-planting and Pendimethylene @ 5.5 ml/litre can be

applied as pre-emergence. Post emergence can be applied with 2-4-D @ 3ml/litre of water.


10/27

Draft copy

6.1.2 Irrigation: Knee high stage, tasseling and silking, and grain filling stages are mostcritical for moisture stress. Light irrigation should be applied to the maize crop at these

stages depending on the soil moisture status and irrigation facilities.

6.1.3 Detasseling: If weather condition is normal (high humidity and temperature less than

38

oc

), 30% plants can be detasseled, which helps to increase maize production up to 7%.

6.1.4 Harvesting: Crop should be harvested after physiological maturity. Maize can be

harvested when black layer is formed on maize grains.

6.1.5 Drying: Maize ears should be sun dried for 3-4 days and before shelling. Grains

should be dried on the tarpaulin and covered during the night. When the grain moisture is

reduced down to 12%, then grains are either stored in metal bins or kept in sealed bags

after processing of seeds.

7.Reasons for release

Arun-4

Arun-4 is the number one preferred early variety by farmers (Annex 33). Thevigorous growth, early maturing habit, good taste and good husk cover are thepositive aspects of Arun-4 as compared to previously released varieties.

It is moderately resistant to major maize diseases like Turcicum leaf blight (TLB),Helminthosporium leaf blight (HLB) and Gray leaf spot (GLS). The infestation of

stem borer in Arun-4 is minimum (Annex 32).

Arun-4 is highly lodging resistant. Local varieties are highly lodging prone. Thus,Arun-4 addresses the real need of the farmers.

Mean height of Arun-4, is 200.32 cm which are tall enough to fulfill the need offodder for livestock for the farmers

Arun-1 EV

Arun-1EV performs better in farmers field. The vigorous growth, early maturinghabit, good taste and good husk cover are the positive aspects of Arun-1EV as

compared to previously released varieties.

It is moderately resistant to major maize diseases like Turcicum leaf blight (TLB),Helminthosporium leaf blight (HLB) and Gray leaf spot (GLS). The infestation ofstem borer is minimum (Annex 32).

Arun-1 EV is highly lodging resistant. Local varieties are highly lodging prone.Thus, Arun-1 EV addresses the real need of the farmers.

Pool-17 E

Since Pool-17 E variety is short in plant height and strong stem, there is no lodgingproblem in this variety.

Pool-17 E variety escape drought stress during the flowering time because of early inflowering.


11/27

Draft copy

It is moderately resistant to major maize diseases like Turcicum leaf blight (TLB),Helminthosporium leaf blight (HLB) and Gray leaf spot (GLS).

Since Arun-4, Arun-3 (Arun-1EV) and Pool-17 E are early in maturity thesevarieties fit in rice-wheat-maize cropping system and vegetables can be grown afterharvesting them.

Releasing these varieties creates a better opportunity for commercialization in maizeseed production in private sector and could benefit the farmers, seed growers andothers, who are involved in seed production and distribution chains.

Finally, the release of these varieties will provide varietal choices to the farmers andcontribute to the food security in the mid hills and terai of Nepal.

8. Seed supply situationNMRP has been maintaining numbers of inbred lines and many released and prereleased

maize varieties since many years. Although the available seed of these inbred lines and

hybrids are not sufficient for selling in the market but it can provide sufficient amount of

source seed for seed multiplication purpose as demanded by the interested stakeholders.

Pattern of stability for grain yield:

Yield stability is the ability of a genotype to avoid substantial fluctuations in yield over arange of environments. Varieties with high and stable performance are desirable. So stability

analysis was performed using regression method;

The varieties having regression coefficient (b) nearly equal to 1 was considered stable for all

environments. The b values significantly less than 1, indicating the constant expression of

the traits under the range of environments and better adaptation to poor environments. The b

values more than 1, which indicates their responsiveness to changes in environmental

conditions and specific adaptation to favorable ones. Therefore, Arun-4 and Arun-1 EV are

stable varieties for all environments (both mid hills and terai) hence their regression

coefficients (b) are nearly equal to 1 and these varieties are most suitable for these regions

because their grain yields are above the average yields. The standard error of mean and

range of grain yield of Pool-17 E are smallest among the tested varieties. And its regression

coefficient (b) less than 1 and grain yield is below the average yield, so this variety is stableunder wide range of environments and best alternative of Arun-4 and Arun-1 EV.
