Description The green revolution fulfilled the food demand of crowded
millions. From the time of green revolution to till date high
yielding and fertilizer responsive varieties have evolved to
increase the production per unit area.
To improve the productivity
only major nutrients are concentrated almost in all crops. Though
the importance of micronutrient realized during past decades in
most of the crops but it is not effectively materialized in general
crop cultivation practices. The micronutrient deficiencies in soil
are not only hamper crop productivity but also deteriorating the
produce quality.
World health organization (WHO) has estimated
that over 3 billion people in the globe suffer from the micronutrient
malnutrition and about 2 billion people of these have iron
deficiency. Iron is one of the 16 essential elements needed for
plant growth. Iron is used for the synthesis of chlorophyll and is
essential for the function of chloroplasts. Zinc is involved in
membrane integrity, enzyme activation, and gene expression.
Rice, sorghum and corn are Zn sensitive and sorghum, sugarcane,
groundnut, soyabean, beans, grapes, vegetables and citrus are
highly Fe sensitive crops.
To overcome these problems foliar
spray is being recommended but it is not crop specific or soil
specific recommendation. Keeping these problems in the view,
recently development of micronutrient efficient genotypes,
creating awareness of micronutrient dose, crop specific micronutrient
uptake and accumulation are vital to improve productivity
and to address human health problems. In this paper
we discussed the importance of iron and zinc in agriculture and
their role in crop plants and ways to improve the crop productivity
as well as human health.
