Abstract

A field experiment was conducted during rabi seasons of 2013–14 and 2014–15 at medium black soil of Chhindwara district of Madhya Pradesh to study the productivity, quality and storability of onion (Allium cepa L.) as influenced by different levels of nitrogen and sulphur. The experiment was conducted with five levels of nitrogen (0, 80, 100, 120 and 140 kg/ha) and four levels of sulphur (0, 15, 30 and 45 kg/ha) and their all possible combinations in factorial randomized block design with three replications in onion variety ‘Agrifound Light Red’. Among different levels of nitrogen, the highest level under consideration (N4: 140 kg N/ha) recorded significantly highest bulb yield (313.69 kg/ha) besides the significantly superior quality and storability parameters over remains. In case of sulphur levels, the second highest level under consideration (S2: 30 kg S/ha) proved superior over S2: 45 kg S/ha in terms of productivity (313.97 kg/ha) and quality (TSS 11.20%). However, storability parameters recorded significantly superior with control (S0: 0 kg S/ha) which recorded minimum physiological weight loss (4.57 and 5.98% at 30 and 60 DAH, respectively) and lowest rotting per cent (3.60 and 10.66 at 30 and 60 DAH, respectively).
