1) Soil test data already available in the laboratory will be compiled and nutrient indices will be worked out to have an idea about changing pattern of the soil fertility status.
2) Twenty four on-farm trials will be carried out each year at different areas of the red and lateritic soil zones of Birbhum and Bankura districts of West Bengal through active participation of the farmers. Four crops viz. rice, mustard, potato and vegetables, commonly cultivated in red and lateritic soil zones, will be used for this programme with six trials for each crop.
The common treatments for each of the trials will be as follows:
i) Farmers practice
ii)100% State recommendation (NPK)
iii) 150% State recommendation (NPK)
iv) Soil test based recommendation ( 100%NPK) + lime + secondary and micronutrients.
v) 150% Soil test based recommendation (NPK) + lime + secondary micronutrients
4) Crops to be cultivated: Four crops viz. rice, mustard, potato and vegetables will be included in the trials. Exact nature of the vegetable to be grown will be decided after selection of the sites.
i) Initial soil analysis of the trial plots will be carried out in order to develop soil test based nutrient recommendation.
ii) Growth and yield attributes and final yield values will be collected for each trial.
iii) Final analysis of the soils will be done to assess the residual fertility.
6) Awareness Programmes:
Farmer-Scientist Meets will be organized in the project locations for disseminating the results of soil test based fertilization.
