The preliminary analysis shows that water and fertilizer play an important role in agricultural production. But addition of irrigation has not resulted in any increase in overall food grains production. This means that we need to look at microlevel practices. Trend and regression analysis also show that effects due to these factors are marginal.

These statements can lead to decision conclusions only after detailed studies based on data at the level of a taluk or district. Such a study will reveal the requirements and limits. Microlevel experimentations by individual farmers have shown increased yields through proper application of water and organic fertilizers.
