Effect of Phosphorus on Different Varieties on Growth and Yield of Field Pea (Pisum sativum L.)

Abstract

During the rabi season 2023-24, a field experiment was carried out at Pandit Deen Dayal Upadhyay Institute of Agriculture Science, Utlou, Bishnupur District, Manipur, India. The treatment comprised of three different phosphorus levels (0,40 and 60 kg/ha) and three varieties V1 – Prakash, V2 – Rachna, V3 – Aman with a total of 9 treatment combinations. The experiment was laid out in a factorial randomized block design (FRBD) with three replications. The results reveal that the most of the growth character viz. plant height(cm), number of branches per plant, fresh weight and dry weight per plant(g), number and dry weight of nodules were recorded maximum on Aman (V3) and minimum values were recorded on Prakash (V1).The maximum yield character such as number of pods per plant, number of seed per pod, pod length(cm), stover yield (q/ha), test weight (g), harvest index (%) were recorded significantly higher under variety Aman (V3) followed by Rachna(V2) and Prakash(V1).Among the phosphorus levels 60 kg P2O5/ha recorded higher growth attribute, yield  attribute and yield of pea  as compared to to other phosphorus which was followed by 40 kg P2O5/ha and 0 kg P2O5/ha. The treatment combination 60 kg P₂O₅/ha + Aman (P3V3) was found best for pea cultivation. Therefore, it can be concluded that using 60 kg P₂O₅/ha + Aman (P3V3) proved to be more productive and profitable for the cultivation of pea during rabi season in Manipur climate condition.
