Manures and fertilizers
-
Farm yard manure at 25 t/ha for irrigated crop and at 12.5 t/ha for rainfed crop is applied. For irrigated crop both basal (30:40:20 kg NPK /ha) and top dressing (30 kg N /ha) is done. Whereas for rainfed crop basal dressing only is given. (Depending on the soil type, crop to be grown).
-
The dosage of fertilizer will be less in the rainfed conditions when compared to irrigated conditions. If the rainfall is favourable, top dressing is resorted to @ 10-20 kg N/ha.
-
Application of fertilizers, especially N, was found to increase the green fodder yield in cereals by 2-3 times. Experiments conducted in North Indian conditions revealed that green fodder(GF), dry matter (DM) and crude protein (CP) yield were increased considerably by N application on fodder sorghum.
-
Biofertilizers viz., Azospirillum + Phosphobacterium mixture both as seed treatment and soil application is recommended @ 3 packets (600 g) for seed treatment and 10 packets (2000 g) for soil application per hectare.
