Response of organic manures with macro and micro nutrients on growth and yield of onion

Abstract

An experiment was conducted to find out the combined effect of organic manures [farm yard manure (FYM), vermicompost, poultry manure and bone meal], macro nutrient (Sulphur) and micro nutrients (Boron and Zinc) on growth and yield of onion cv. N-53 in a Randomized Block Design with three replications. The results showed that maximum plant height (56.85 cm), maximum number of leaves (13.26),leaf length (50.45 cm), leaf width (1.51 cm), neck diameter (1.917), bulb length (7.06), bulb scale (8.300), bulb diameter before curing (6.167), bulb diameter after curing (5.263), bulb weight per plant (99.32 gm), bulb yield per plot (2.979 kg) and bulb yield per ha. (297.93 q)was recorded under the T10[FYM + Vermicompost + Poultry manure + Bone meal + Sulphur + Boron + Zinc]. While minimum plant height (44.13 cm), number of leaves (9.36), leaf length (39.39 cm), leaf width (1.31 cm), neck diameter (1.103), bulb length (4.18 cm), bulb scale (5.287), bulb diameter before curing (3.637), bulb diameter after curing (3.080), bulb weight per plant (45.470 gm), bulb yield per plot (1.364 kg) and bulb yield per ha. (136.36 q) was recorded in treatmentT1 (Control).
