Wheat Crop - HD 2967 (Step 3)
Fertilizer Management
-
It is recommended to use 60 Kg N, 24 kg P and 16 kg K/acre. Entire P and K and half of N can be applied as basal dose. The remaining half can be split in two equal doses, one immediately after irrigation and remaining after second irrigation.
APPROACHES FOR IMPROVING SOIL HEALTH
Following strategies may help in reversing the adverse effects on soil:
-
⬤ Adoption of resource conservation technologies like zero tillage & happy seeder. ⬤ Residue management - Incorporation or surface residue retention to enhance the soil organic matter. ⬤ Developing new and improving the available machinery for residue management and conservation agriculture. ⬤ Introduction of leguminous crops like moong bean to regain & build up the soil health. ⬤ Green manuring to increase soil organic matter. ⬤ Balanced use of fertilizers ⬤ Application of NPK in proper proportion along with FYM and need based application of Zn, Mn, Fe, Cu, Mo and B as micro-nutrients for optimum yields.
APPLICATION OF MICRONUTRIENTS
For Zinc deficiency:
-
⬤ Zinc sulphate at the rate of 10 kg/ac once in a year or 4 kg/ac to each crop during rabi and kharif season. If zinc deficiency symptoms are visible in the crop then spray 0.5 % zinc sulphate solution.
For Manganese deficiency:
-
⬤ A spray 0.5% solution of MnSO4 is advisable. Dissolve 1 kg MnSO4 in 200 liter of water per ac. First spray should be done 2-5 days before first irrigation and remaining 2-3 sprays at one week internal.
For Sulphur deficiency
-
⬤ Soil application of sulphur or spray can bone for correcting deficiency. Apply Sulphur 80% WDG @ 3-4 kg/ac at the time of sowing or just before first irrigation.
