Effect of Organic Manure and in Organic Fertilizer on Growth Yeild and Quality of Onion (Allium cepa L.)

An experiment entitled Effect of Organic manure and inorganic fertilizer on growth, Yield and Quality of Onion (Allium cepa L.)” was conducted at Horticulture research farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment framed was intended to study the effect of different organic manures, inorganic fertilizers on growth, yield and quality of onion. The results of the present investigation indicated that, the combined application of organic manures and inorganic fertilizers has significant influence the growth, yield and quality parameters of onion as regards to the treatment T8 (70 % RDN + 30 % FYM) was found superior for most of the traits under study and it was at with treatment T7 (70 % RDN + 30 % Vermicompost), T5 (80 % RDN + 20 % FYM) and T4 (80 % RDN + 20% Vermicompost). The maximum values of growth parameters like plant height (91.44 cm) and number of leaves (10.53) at harvest were recorded in treatment (T8). The yield contributing characters like diameter of bulb (8.70 cm), number of bulbs (41.33), yield per plot (5.07 Kg), yield per hectare (33.77q) were found to be maximum in T8. The parameters like weight of fresh bulb (181.70 g), weight of dry bulb (168.07 g) was high in T6 and T8 respectively. Hence, it can be concluded that, for getting optimum growth, higher yields the crop should be supplied with the 70 per cent recommended dose of N, P, K, fertilizers (100:50:50 kg/ha), in which the 30 per cent quantity of N should applied through farmyard manure.
