INFLUENCE OF DATE OF SOWING AND DIFFERENT LEVELS OF PHOSPHORUS ON GROWTH AND YIELD OF GARDEN PEA (Pisum sativum L.)

Abstract

An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October, 2017 to March, 2018. The experiment consisted of two factors. Factor A: three levels of sowing time, S 1 : 15 November, S 2 : 25 November, S 3 : 5 December and Factor B: four levels of phosphorus fertilizer, P 0 : Control (No Phosphorus), P 1 : 50 kg P 2 /ha, P 2 : 75 kg P 2 O 5 /ha, P 3 : 100 kg P 2 O 5 /ha. This experiment was laid out in Randomized Complete Blocked Design with three replications. Sowing time and phosphorus application influenced significantly on most of the parameters. In case of sowing time, maximum plant height (46.72 cm), pod length (8.30 cm), number of pods per plant (12.10), number of seeds per pod (4.62) and green pod yield (8.48 t/ha) were recorded from S 2 treatment. In case of phosphorus application, maximum plant height (48.56 cm), pod length (8.68 cm), number of pods per plant (12.70), number of seeds per pod (4.90) and green pod yield (9.23 t/ha) were found in P 2 treatment. Among the treatment combination, S 2 P 2 treatment gave the highest green pod yield (10.50 t/ha) and the lowest (4.48 t/ha) was obtained from S 3 P 0 treatment. The highest gross return (Tk. 315000), net return (Tk. 181248) and BCR (2.35) were obtained from the treatment combination of S 2 P 2 where the lowest gross return (Tk. 134400), net return (Tk. 3146) and lowest BCR (1.02) were obtained from S 3 P 0 . So, garden pea may be sown at 25 November along with 75 kg P 2 /ha for commercial green pea production in Dhaka region. O 5 O 5
