Physiological Response of Onion to Water Stress and Bio Fertilizers (9783838361659)
In this study, the results indicated that maximum marketable bulbs yield (t/fed), and the minimum total losses percentage in bulb yield are producing by irrigation at 24cb tensiometer reading (2328.38 m3 /fed) and fertilization with 75% from recommended NPK i.e. 75 kg N + 30 kg P2O5 + 18 kg K2O/fed plus spraying 1000 ppm Amino Total at three times or spraying 4000 ppm Soft Guard at three times. Irrigation at 36cb tensiometer reading (1097.70 m3/fed) and reducing mineral fertilization (NPK) by 25% with spraying 4000 ppm Soft Guard or 1000 ppm Amino Total for three times maximized water use efficiency by 41.11% and reducing total losses percentage in bulb yield after six months by 39.12% compared with irrigation at 24cb tensiometer reading (2328.38 m3 / fed) and fertilization with 100% NPK as an average in both seasons.
