Effect of calcium and boron on growth and yield of groundnut (Arachis hypogaea L.)

Abstract

In 2023, a groundnut experiment was carried out at the Department of Agronomy's Crop Research Farm (CRF) during the kharif season. With ten treatments and three replications, the experiment was set up using a Randomized Block Design (RBD). As a baseline application and a control, the treatments included three levels of calcium (15, 20, and 25 kg/ha) and three levels of boron (1.0, 1.5, and 2.0 kg/ha) (20:60:40 kg N: P: K/ha). Following Treatment 9, which involved applying 25 kg of calcium per hectare and 2.0 kg of boron per hectare, the maximum plant dry weight (28.58 cm), number of pods per plant (21.99), number of kernel per pod (1.99 kg/ha), and highest test weight (219.21 g) and seed yield (3020.80 kg/ha) were all recorded. Additionally, the benefit cost ratio (2.41) was noted in the aforementioned.
