Abstract:
This experiment was carried out during Rabi season of 2021-22 at Agricultural Research Farm of faculty of Agricultural Sciences and Allied Industries, Rama University, Mandhana, Kanpur Nagar (U.P). The present experiment was laid out in split plot design, the experiment consists of three dates of sowing in main plot viz;5 October date (D₁), 15 October date (D₂), 30 November (D₃) and 4 treatments viz; where granule sea weed extract (T₁) Control, (T₂)15 kg ha^-1 granule sea weed extract, (T₃)20 kg ha^-1 granule sea weed extract (5 Tonns /ha), (T₄) 25 kg ha^-1 granule sea weed extract in sub plot with three replications in Indian mustard. The results of this experiment result indicate the growth parameter viz; plant height, number of primary and secondary and yield attributing character and yield Indian mustard viz; number of siliqua/ plants, siliqua length, number of seed/siliquae, weight of siliqua, weight of seed / plant and test weight and seed and straw yield of was recorded maximum from date of sowing at (D₂) 15 October which were statistically at par with date of sowing at 5 October. The least number of primary branches was estimated from 30 November date of sowing of mustard crop. Similarly, in case of soil application of sea weed extract on growth and yield attributing character and yield of mustard crop with was documented from soil application of granule sea weed extract (T₄) 25 kg ha^-1 which were statistically higher than soil application of granule sea weed extract 20 kg ha^-1. However, the minimum seed yield of mustard crop was recorded from control plot. However, the least Number of seed per plant was estimated from control plot. The maximum net return and B:C ratio of mustard crop was recorded from date of sowing at 15 October (Rs. 60,836 ha^-1) followed by with date of sowing at 5 October. (Rs. 78,884 ha^-1). The minimum net return of mustard crop was recorded from date of sowing at 30 November. (Rs. 70,102 ha^-1)Although, soil application of sea weed extract was significantly influencing the net return of mustard crop. The maximum net return of mustard crop was documented from soil application of granule sea weed extract 25 kg ha^-1 (Rs. 76,965 ha^-1) followed by soil application of granule sea weed extract 20 kg ha^-1. (Rs. 71,671 ha^-1) However, the minimum net return of mustard crop was recorded from control plot. (Rs. 64,162 ha^-1).
