Effect of different levels of nitrogen and phosphorus on yield and quality of onion seed (Allium Cepa L.) C.V. Agrifound light red

Abstract

The present investigation entitled “Effect of different levels of nitrogen and phosphorus on growth, yield and quality of onion seed (Allium cepa L.) C.V. Agrifound Light Red” was carried out at Research area, College of Agriculture, Gwalior during 2020-21. The treatments consisted of factorial combinations of four levels of nitrogen (0, 40, 80 and 120 kg N ha-1) and Phosphorus (0, 40, 80 and 120 kg N ha-1) laid out in Factorial Randomized Block Design with three replications. Result of the study revealed that; N and P had shown a highly significant effect on yield and quality and yield parameters like test weight g, number of seeds per umbel, weight per umbel, seed yield per plot (g) maximum (395.48 g) recorded with N4 120kg/ha + P4 120kg/ha, seed yield per hectare (q) is maximum (9.89 q) found with N4 120kg/ha + P4 120kg/ha and on quality parameters like number of flowers per umbel, umbel diameter in cm, potassium content in leaf (%) is maximum (2.50%) found with N4 120kg/ha + P4 120kg/ha which were significantly superior over the rest of other treatments. This can be recommended for use by potential onion investors or farmers with high initial capital in the gird region of northern Madhya Pradesh
