Standardization of pre-sowing treatments of bio-fertilizer and botanicals on growth, yield and yield attributing traits of linseed (Linum usitatissimum L.)

Abstract

Field experiment was conducted to standardize pre-sowing treatments of bio-fertilizer and botanicals on growth, yield and yield attributing traits of linseed [cv. GP(I) 101]. The experiment involved one genotype replicated thrice with 12 distinct treatments using Randomized Block Design. The findings demonstrated notable results across various parameters but significantly higher values were recorded for treatments involving neem leaf and neem seed extract (T11) across all parameters, indicating their potential efficacy in enhancing linseed growth and yield like field emergence (89.10%), plant height (72 cm), daysto 50% flowering (81 days), number of primary branches per plant (8.46), number of secondary branches per plant (28), days to maturity (111 days), number of capsules per plant (143), number of seeds per capsule (8.8), seed yield per plant (7.53 g), seed yield per plot (91.2 g), seed yield per hectare (11.58 kg), test weight (6.40 g), biological yield (26.06 g ), harvest index (36.04%) and seed index (8.58).
