Possible impact of paclobutrazol on field pea (Pisum sativum L) yield and yield attribute

Abstract

Field pea (Pisum sativum L) is a multipurpose and nutritious legume that act as an important part of human agriculture and nutrition. The protein-rich seeds of the field pea are a common food in many cultures which make them a valuable source of nutrition. Field pea is also a crucial part of sustainable agricultural systems due to its capacity to fix atmospheric nitrogen and hence increasing soil fertility. Paclobutrazol, a growth retardant that inhibit stem elongation and shorten the height of a plant. It also modifies the canopy structure by enhancing the number of branches and increase seed yield in plants. Application of Paclobutrazol on field peas variety ‘VL-42 (L)’ through foliar spray delayed the appearance of first flower with such a trend that increased in number of days with increase in concentration. Paclobutrazol treatment was found to synchronise the flowering in the field peas. Paclobutrazol @90 ml/ha was the best treatment with highest yield, highest pods per plant and highest seeds per pod and also the most effective treatment to produce the highest yield.
