Effect of spacing and bulb size on growth, yield and economics of onion seed crop in Haryana

Abstract: The field experiment entitled Effect of spacing and bulb size on growth, yield and economics of onion seed crop in Haryana was conducted with cultivar HO 4 at Vegetable Seed Production and Research Farm, Jagdishpur, Sonepat during Rabi season of 2015-16 and 2016-17. The nine treatment combinations comprising of three bulb size, i.e., big size (≥5.5 cm diameter), medium size (4.5 to 5.4 cm diameter) and small size (3.5 to 4.4 cm diameter) and three spacing, i.e., 45×45, 45×30 and 30×30 cm were laid out in randomized block design in plot size of 2.7×2.7 cm and replicated four times. Based on pooled data of two years, the increasing trend was observed in plant height with the increase in spacing. The results indicate that the significantly highest plant height at 30, 60 and 90 days after planting (38.72, 49.41 and 68.37 cm) was reported in crop raised with large size bulbs followed by medium size bulbs at each stage of crop growth except at 60 DAP, which was found at par, respectively. The crop at widest spacing had the tallest plants (35.47, 50.09 and 67.69 cm) irrespective of growth stages and these figures were found at par with plant height of crop at medium spacing. The crop raised with big bulbs recorded significantly maximum number of umbels per plant (9.82), which was significantly superior to the number of umbels per plant in crop raised with small bulbs but it was statistically at par with the number of umbels per plant crop raised with medium size bulbs. The interaction effect of these two parameters under study clearly shows that the crop raised with big bulbs at widest spacing gave significantly higher seed yield (5.90 q/ha) than rest of the treatment combinations. The data pertaining to economics of this crop reveal that the maximum net return and benefit to cost ratio was obtained from the crop raised with big bulbs (₹238140/ha and 2.26) and widest spacing (₹241168/ha and 2.27), respectively.
