Effect of sowing dates and crop geometry on growth and seed yield of dill (Anethum sowa L)

Abstract

A field experiment was carried out with an objective to find out the optimum sowing time and crop geometry in dill for strealising higher yield and benefit. Fifteen treatment combinations comprising of five dates of sowing viz., I October, th th th th 15 October, 30 October, 15 November and 30 November in main plots and three crop geometry viz., 40 cm x10 cm, 50 cm x 10 cm and 60 cm x 10 cm spacing in sub plots were taken in split plot design with three replications. th The results revealed that sowing of dill on 15 October exhibited significantly higher plant height and number of branches per plant at all the growth stages with maximum number of umbels per plant (60.15), umbellates /umbel (44.10) and seeds /umbellate (57.18). The maximum test weight (4.89 gm) and seed yield (1631.75 kg /ha) was recorded in the same treatment. Significantly higher plant height at all the growth stages, yield attributes, and seed yield (908.57 kg /ha) were obtained with sowing of dill at 40 cm x 10 cm spacing over wider spacing. Therefore, sowing th of dill on 15 October at 40 cm X 10 cm spacing was found most suitable for realising higher growth and seed yield.
