Influence of farm yard manure and inorganic N fertilization on performance of garlic under different irrigation regimes

Results of two years field study revealed that farm yard manure improved bulb circumference, bulb weight, number of cloves, bulb yield, N uptake, crude protein content and irrigation water use efficiency. Irrigation based on irrigation water/pan evaporation (IW/PAN-E) =1.6 and 1.2 produced significantly higher garlic bulb yield and bulb weight than that obtained with IW/PAN-E=0.8, but IW/PAN-E =1.2 used less irrigation water than that with IW/PAN-E =1.6. Garlic yield significantly increased with N application upto 125 kg ha-1 . Fertilizer N increased bulb size, weight and irrigation water use efficiency. Crude protein content increased with farm yard manure upto 150 kg ha-1 of N and IW/PAN-E =1.6, while upto 125 kg ha-1 of N and IW/PAN-E =1.2 without farm yard manure. Water use efficiency decreased with irrigation frequency.
