AIM:

TO STUDY ESSENTIALITY

OF MINERALS AND DEFICIENCY

SYMPTOMS OF ESSENTIAL MINERALS ON

PLANT GROWTH.

REQUIREMENTS:CULTURE SOLUTIONS, GRAM OR MAIZE SEEDLINGS,

STERILISED BOTTLES, WEIGHING BALANCE.

THEORY:PLANT REQUIRE MINERALS FOR NORMAL GROWTH

AND DEVELOPMENT.MINERALS WHICH ARE NEEDED IN LARGE

QUANTITY ARE CALLED MACRONUTRIENTS. FOR

EXAMPLES, C, H, O, N, S, P, K, Ca, Mg AND Fe.

MINERALS WHICH ARE NEEDED IN SMALL

QUANTITY ARE CALLED MICRONUTRIENTS. FOR

EXAMPLES, M, Z, B, C! AND M".HYDROPONICS# SOIL LESS CULTURES# TO RAISE

THE PLANTS IN SOLUTION CULTURES WITHOUT

USING SOIL.

HYDROPONICS IS USEFUL$

%a& IN AREAS WITH THIN, FERTILE ANDDRY SOILS

%'& TO FIND OUT THE ESSENTIALITY ANDDEFICIENCY SYMPTOMS OF VARIOUS

MINERALS.

CRITERIA FOR ESSENTIALITY OF AN ELEMENT

IS$

%a& IT IS NECESSARY FOR GROWTH ANDDEVELOPMENT AND IT IS DIRECTLY INVOLVED

IN PLANT METABOLISM.

%'& IT CANNOT BE REPLACED BY ANY OTHER

ELEMENT.

%(& DEFICIENCY OF THE ELEMENT PRODUCES

DEFICIENCY SYMPTOMS. DEFICIENCYSYMPTOMS OR HUNGER SIGNS INCLUDE

CHLOROSIS, STUNTED GROWTH, NECROSIS,

PREMATURE LEAF FALL, MALFORMED

LEAVES.

ESSENTIALITY OF MINERALS CAN BEDETERMINED BY GROWING PLANTS IN$

%a& KNOP)S AND SACH)S CULTURE SOLUTION

WHICH CONTAIN ESSENTIAL ELEMENT SALTS

IN SPECIFIC RATIO DISSOLVED IN DISTILLED

WATER.

%'& SAND CULTURE, *.e. , WELL WASHED,

HEATED PURE QUARTZ SAND, MIXED WITHCULTURE SOLUTION CONTAINING SPECIFIC

SALTS.

PROCEDURE:

+.PREPARE THE SACH)S CULTURE SOLUTION BY

DISSOLVING THE FOLLOWING IN +-

2.GROW FEW GRAM SEEDS TILL THEY BECOME

SEEDLINGS.

0.TAKE 1 STERILISED CONTAINERS A, B, C, D, E.

FILL CONTAINER A WITH NORMAL CULTURE

SOLUTION, B WITH %/N& SOLUTION, C WITH %/Ca& SOLUTION, D WITH %/Fe& SOLUTION, E WITH

%/C& SOLUTION. COVER THEM WITH SPLIT

CORK LID.

3.PUT ONE SEEDLING IN EACH BOTTLE THROUGH

SPLIT CORK AND PROVIDE NORMAL LIGHT,

TEMPERATURE AND OXYGEN TO LET THEMGROW.

1.RECORD YOUR OBSERVATIONS AGTER SOME

INTERVALS OF DAYS.

OBSERVATIONS: SEEDLINGS

RESULT AND

DISCUSSION+.BOTTLE A SHOWS NORMAL SEEDLING

GROWTH.

2.BOTTLE B SEEDLING SHOWS DEFICIENCY

SYMPTOMS FOR NITROGEN LIKE CHLOROSIS

STARTING FROM OLDER LEAVES, DTUNTEDGROWTH.

0.BOTTLE C SEEDLING SHOWS DEFICIENCY

SYMPTOMS FOR CALCIUM LIKE STUNTED

GROWTH OF SEEDLING, NECROSIS AND

CURLING OF LEAVES.

3.BOTTLE D SEEDLING SHOW DEFICIENCYSYMPTOMS FOR IRON LIKE INTERVIENAL

CHLOROSIS AND REDUCED GROWTH.

1.BOTTLE E SEEDLING SHOWS DEFICIENCY

SYMPTOMS FOR CHLORINE *.e. , LEAF WILTING,

CHLOROSIS AND NECROSIS9 SWOLLEN ROOT
