Yield and Economics of Pea (Pisum sativum L.) as Influence by Spacing and Nipping in Manipur

Aims: To study the yield and economics of pea (Pisum Sativum L.) as influence by spacing and nipping in Manipur.

Study Design: Factorial randomized block design (FRBD).

Place and Duration of Study: Experimental field of College of Agriculture, Central Agricultural University, Imphal, Manipur, rabi season of 2013-14 and 2014-15.

Methodology: The treatment combinations involving two factors were S1N1, S1N2, S2N1, S2N2, S3N1, S3N2, S4N1 and S4N2 (Spacing i.e., S1-20X15cm, S2-20X20cm, S3-30X10cm and S4-30X15cm and nipping i.e., N1-No nipping and N2-Nipping.

Results: The pooled results of two years of study revealed that the yield differed significantly at a 5% probability level with different treatment combinations. The number of branches at harvest was significantly affected by both spacing and nipping with maximum branches in treatment combination S4N2 resulting in highest number of pods observed in S4N2 with 11.02 (pooled) and the lowest in S1N1. Spacing and nipping treatment had no significant influence on the pod length. The maximum stover yield was recorded in S1N2 with 27.35 q/ha and minimum in S4N1 with 22.02 q/ha. The highest seed yield of 16.05 q/ha was recorded in S4N2 with highest net return (₹ 2,05392/ha) and cost-benefit ratio (1:4.69). The present study suggests that the spacing of 30x15cm with nipping was found to be the best amongst the treatment combinations in regards to yield and higher feasible net returns.
