Effect of spacing, bulb size and time of planting on onion seed yield (Allium cepa L.)

Abstract

An investigation on Effect of Spacing, Bulb Size and Time of Planting on Onion Seed Yield (Allium cepa L.) was undertaken at the experimental farm, College of Agriculture, V.N.M.K.V Parbhani, during rabi season 2016-2017. The experiment was laid out in factorial randomized block design (FRBD) with three factors replicated twice by using the variety Agri Found Light Red. There were total eighteen treatment combinations. The regarding yield attribute revealed that significantly maximum number of seeds per umbel (819.66, 806.50, 813.25, respectively) was recorded in treatment comprising of spacing at 60 x 45cm, bulb size of 71 - 80 g and planting on 15th October. The interaction effect of S2B2P1 recorded maximum number of seed per umbel (924.50). The maximum seed weight per umbel (6.95, 6.75, 6.70grespectively) was recorded in treatment comprising of spacing at 60 x 45cm, bulb size of 71 - 80 g and planting on 15th October. The interaction effect of S2B2P1 recorded maximum seed weight per umbel (7.82 g,). Maximum seed yield per plant (19.15, 18.94, 18.91 g, respectively) was recorded in treatment comprising of spacing at 60 x 45cm, bulb size of 71 - 80 g and planting on 15th October. The interaction effect of S2B2P1 recorded maximum seed yield per plant (22.39 g,). The maximum seed yield per plot (587.55, 575.66, 593.83 g, respectively) was recorded in treatment comprising of spacing at 60 x 45cm, bulb size of 71 - 80 g and planting on 15th October as compared to the rest of the treatment of onion. The interaction effect ofS2B2P1 recorded maximum seed yield per plot (629.50 g). The maximum seed yield per hectare (6.81, 6.49, 6.49 q/ha, respectively) was recorded in treatment comprising of spacing at 60 x 45cm, bulb size of 71 - 80 g and planting on 15th October. The interaction effect of S2B2P1 recorded maximum seed yield per hectare (7.47 q/ha, respectively). An overall planting of medium sized bulb at 60 x 45 cm on 15th October produces higher yield of onion seed.
