Abstract
A field experiment entitled “Effect of sulphur and boron on seed production of vegetable pea (Pisum sativum L.) in calcareous soils” “was carried out at the experimental field of AICRP on Vegetable Crops, Department of Horticulture, PG College of Agriculture, “Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar during Rabi season (2020-21).”Experiment was conducted in Randomized Block Design with factorial fashion, comprising of five levels of sulphur (0, 10, 20, 30 and 40 Kg ha-1) and three levels of boron (0, 1 and 2 Kg ha-1) to study the effect on growth, pod yield and “seed yield of vegetable pea. Altogether, the experiment consisted of 15 treatments which were replicated thrice. Growth, pod yield and seed yield attributes were studied including economics.”
The significant effects of treatments were observed for growth attributes, pod yield, seed yield and it’s attributes. The ultimate height of plant (58.86 cm) and “number of branches per plant” (4.60) were recorded maximum in treatment combination S4 B2 (40 kg S ha-1+ 2 kg B ha-1). Similar results were also recorded for pod yield related attributes as well as seed yield related attributes.
Among the pod yield attributes, number of green pods plant-1 (23.93), pod length (9.72 cm), green pod yield plant-1 (44.20 g) and weight of 10 pods (75.05g) were recorded maximum with the treatment combination S4 B2 (40 kg S ha-1+ 2 kg B ha-1). “However, S4 B2 (40 kg S ha-1+ 2 kg B ha-1)” exhibited at par with S3B2 (30 kg S ha-1+ 2 kg B ha-1) for” some characters like “number of pod per plant, pod length” (9.60 cm) and weight of 10 pods (78.30 g). When it was concerned to seed yield and its attributes, number of seeds pod-1(9.26), number of seeded pods per plant (12.60), seed yield per hectare (16.73 q) and 100 seed weight (22.56g) were recorded maximum with the treatment combination S4 B2 (40 kg S ha-1+ 2 kg B ha-1). However, S4 B2 (40 kg S ha-1+ 2 kg B ha-1) exhibited to be at par with S3B2 (30 kg S ha-1+ 2 kg B ha-1)” for some characters like, number of seed per pod (9.26), number of seeded pod per plant (12.60), seed yield per ha. (16.73 q ha-1) and 100 seed weight (21.96 g). So far as the economics of the trial was concerned, the treatment combination S4 B2 (40 kg S ha-1+ 2kg B ha-1) gave the maximum net return (₹.1,88,316.00) as well as benefit cost ratio (3.50).
“Thus, the present study suggested that treatment combination S4 B2 (40 kg S ha-1+ 2 kg B ha-1)” exhibited superiority over rest of the treatment combinations with respect to almost all the characters of vegetable pea.”
