Abstract


Variety and different nitrogen levels effect on the yield and quality of linseed. The experiment is to exploring the effect of different levels of nitrogen on morphology, yield and quality of linseed genotypes conducted in Randomized Complete Block Design (RCBD) with split-plot arrangements. The experiment was comprised of two factors. Factor-A, linseed cultivars, V1 (Chandni), V2 (LS-29), V3 (LS-90) and V4 (LS-95) and factor-B, five nitrogen levels, N0 (control), N1 (25 kg ha-1), N2 (50 kg ha-1), N3 (75 kg ha-1) and N4 (100 kg ha-1). Among tested cultivars Chandni proved to be superior over other cultivars. Different nitrogen levels also had significant effect on most growth and yield parameters but had non significant effect on number of branches per plant, 1000-seed weight and seed oil content. Maximum number of plants per m-2 (47.18), plant height (72.66 cm), technical stem length (62.92 cm), number of branches per plant (5.38), number of capsules per plant (54.30), number of seeds per capsule (6.16), 1000-seed weight (6.78 g), seed yield (607.8 kg ha-1), biological yield (3117.5), harvest index (23.8%), seed oil content (39.2%) and oil yield (221.9 kg ha-1) were recorded from plots where nitrogen was applied at rate of 75 kg ha-1 (N3). It is concluded that Chandni cultivar performed better with the application of 75 kg ha-1 N.
