Pod and seed production potential of vegetable pea (Pisum sativum L.) as influenced by different levels of sulphur and boron in calcareous soil of north Bihar

Vegetable pea is one of the relevant vegetable crops grown in the cool season all over the India. Sulphur deficiency is becoming more prevalent in Bihar due to the less use of boron and sulphur-containing fertilizer in calcareous soils and the consequent decrease in sulphur and boron nutrients. On the other hand, organic matter-rich manures, are utilized in very small quantities which is a source of a macro-and micronutrients, including sulphur and boron. As a consequence, soils have become deficient in sulphur and boron, which is detrimental to crop production. In the absence of these sulphur and boron in the soil, different legume crops such as vegetable pea suffer from reduced growth, yield and nodule formation.

In this field investigation during 2020-2022, experiments were conducted in Factorial Randomized Block Design using fifteen different combinations of Boron and Sulphur doses in Azad Pea-3 variety of vegetable pea in three replications and different pod and seed yield attributing traits were studied.

Among the different treatments, it has been inferred that treatment combination 40 kg S ha^-1 + 2 kg B ha^-1 exhibited superiority over rest of the treatment combinations with respect to pod and seed yield attributes of vegetable pea.
