Factors Affecting Crop Productivity
Soil
The soils in which
crops are grown, water which is the life of the plant. The physical properties for the
plant growth and gives mechanical support to plants. Supply nutrition to plants and hence
soil does not merely give mechanical support but also food to the plants. Every soil has
its natural fertility which differs from soil to soil and it can now be supplemented by
adding chemical fertilisers in desired quantities.
Water
Water is the life of
plant and must be supplied in proper quantity. Too much water may suffocate the plant
roots and too little may not be able to sustain the plant. Methods of supplementing rain
water by irrigation should also be known properly for obtaining bumper crops.
Plant
The soil and water are
two variables which either have to be suitably adjusted for the plant to grow or the plant
should be so bred and selected that it will adjust to a given soil and water condition.
Crop like sugarcane takes a whole year to mature and fruit trees live over a number of
years and need irrigation besides rain water. On the basis of the life of a crop, it is
known as seasonal, two seasonal, annual or perennial. Thus there are a variety of crops
and plant breeders are constantly at work to evolve varieties which will suit the given
soil and water conditions e.g., those which may stand drought condition, those which will
absorb more nutrients and convert them into food giving bumper yields, varieties which
will be resistant to diseases etc. It is an absorbing study, which must be made.
- Understanding the soil fertility and
water management systems developed over years.
- Change in the ecosystem forest
coverage, livestock holding pattern and lifestyle in rural areas.
- Increase in agricultural by products
and domestic garbage, which can be used for composting.
- Adaptation of dairy farming with
high-yielding cattle and buffaloes, stall feeding and installation of biogas plants can
generate significant quantity of farmyard manure.
- The soil productivity can be further
enhanced through soil and water conservation, improved drainage, contour bunding and
establishment of live hedges.
- Application of organic manure and
bio-fertilisers, adaptation of tree-based farming.
- Integrated pest management can be
promoted to boost the yields.
- Replacement of local seeds with
certified seeds, change of crops, use of improved farm implements, mineral nutrients,
plant protection measures and installation of irrigation system are some of the new
initiatives to further enhance the crop yields.
- Post harvest processing, storage and
marketing are other areas where both small and large holders have been incurring heavy
losses. Introduction of modern technologies and infrastructure development.
