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

Abstract

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.
