Influence of Spacing and Different Level of Macronutrients on Growth and Yield of Garden Pea (Pisum sativum L.)

Abstract

An experiment was conducted in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, on garden pea, during the period of November, 2018 to January, 2019. The experiment was outlined in Randomized Complete Block Design (RCBD) with three replications. The experiment consisted of two factors; 3 levels of plant spacing. S1 (30 cm × 10 cm), S2 (30 cm × 20 cm) and S3 (30 cm × 30 cm) and 4 levels of macronutrient management viz., T0 (N0P0K0S0 kg ha-1), T1 (N15P25K25S5 kg ha-1), T2 (N30P50K50S10 kg ha-1) and T3 (N45P75K75S15 kg ha-1). Results indicated that the highest seed yield (8.38 t ha-1) and pod yield (10.56 t ha-1) were found from S1 (30 cm × 10 cm) compared to other plant spacing. Considering macronutrient application, the highest seed yield (7.57 t ha-1) and pod yield (9.12 t ha-1) were recorded from T2 (N30P50K50S10 kg ha-1), control treatment T0 (N0P0K0S0 kg ha-1) showed lowest. In terms of combined the highest seed yield (9.20 t ha-1) and pod yield (11.82 t ha-1) were achieved from S1T2, the lowest seed yield (4.64 t ha-1) and pod yield (5.93 t ha-1) were obtained from S3T0. In the combination of spacing and macronutrient dose, the highest Benefit Cost Ratio (BCR) (3.00) was recorded from the combination of S1T2 treatment and the lowest BCR (1.02) was obtained from S3T0 treatment and this combination can be recommended for farmers field evaluation.
