Effect of various organic manures with biofertilizers on growth, yield and economics of onion (Allium cepa L.)

An experiment was conducted at the Organic Production Block, College of Horticulture, VCSG Uttarakhand University of Horticulture and Forestry, Bharsar, Uttarakhand during the year 2016. The experiment was laid out in randomized block design with three replicated and 9 treatments viz., T1 Control, T2 Vermicompost, T3 FYM, T4 Goat manure, T5 Neem cake, T6 Vermicompost + FYM + Goat manure, T7 Vermicompost + FYM + Neem cake, T8 Vermicompost + Goat manure + Neem cake, T9 FYM + Goat manure + Neem cake. The observations were recorded on different growth and yield attributes. Further, economics of different treatments was also worked out. The analysis of variance revealed significant differences among the treatments for all the characters under study. The treatment T3 FYM due to its persistent performance for yield (324.46 q/ha), gross income (Rs. 324460.00 q/ha), net returns (Rs. 251680.04 q/ha) and higher benefit: cost ratio (1:3.45). Thus, it can be concluded from the findings that application of FYM (2.8kg/1.2m2 ) can be recommended for commercial cultivation of onion. | Effect of various organic manures with biofertilizers on growth, yield and economics of onion (Allium cepa L.)
