This can be attributed to structural weaknesses of the agriculture sector reflected in low level of public investment, exhaustion of the yield potential of new high yielding varieties of wheat and rice, unbalanced fertiliser use, low seed replacement rate, an inadequate incentive system and post harvest value addition.
Some of the other reasons that can be attributed to the low agricultural productivity in our country are (i) Lack of irrigation facilities in major part of the cultivated land; (ii) Small and fragmented land holding with the cultivators; (iii) Lack of timely availability of quality seeds, fertilizers for providing all major and minor nutrients for the crops and insecticides in many parts of the country; (iv) Lesser availability of photo period as compared to countries like those in Mediterranean sea areas.
