Influence of Date of Sowing and Different Levels of Phosphorus on Growth and Yield of Garden Pea (Pisum sativum L.)

Abstract

The experiment was carried out at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during October 2017 to February 2018 to find out the growth, yield and economic benefit of garden pea as influenced by date of sowing and different levels of phosphorus. The research comprised of two factors: Factor A: Sowing time (three levels) as S1=15 November, S2=25 November, S3=5 December and Factor B: Phosphorus fertilizer (four levels) as P0= Control (No Phosphorus), P1=50 kg P2O5/ha, P2=75 kg P2O5/ha, P3=100 kg P2O5/ha.  The experiment was set up in randomized complete block design (RCBD) with three replications. Sowing time and phosphorus influenced significantly on most of the parameters. Sowing time, S2 (25 November) performed best in number of pods per plant (12.10), number of seeds per pod (4.62) and green pod yield (8.48 ton) per hectare and minimum in S3 (5 December) treatment. Application of phosphorus, P2 (75 kg P2O5) performed best in number of pods per plant (12.70), number of seeds per pod (4.90) and green pod yield (9.23 ton) per hectare and minimum in P0 (control) treatment. Among the treatment combination S2P2 treatment gave the highest green pod yield (10.50 t/ha) and the lowest (4.48 t/ha) was obtained from S3P0 treatment. Combination of 25 November sowing with 75 kg P2O5was the best for growth, pod formation and seed formation of garden pea. From the economic point of view, the highest Benefit Cost Ratio (BCR) was (2.35) noted from S2P2 and the lowest (1.02) from S3P0. It was evident that the S2P2 gave the best performance for the growth, yield and economic benefit of garden pea. So, it was concluded that, the combination of 25 November sowing with 75 kg P2O5 can be used for commercial garden pea production.
