Optimizing seed rate of bold seeded varieties of chickpea (Cicer arietinum L.) for enhancement in seed quality and yield

Abstract

The study was conducted on HC 3 variety of chickpea to optimize the seed rate for bold seeded varieties during rabi 2022-23. The results revealed that there was a decrease in plant stand establishment, days to flowering, and plant height as the seed rate is reduced from 120 kg to 72 kg/ha. However, the seed yield per plant increased when the seed rate is reduced. The highest seed yield of 2010 kg/ha was recorded in seed rate of 84 kg/ha, but it decreased to 1727 kg/ha in seed rate of 72 kg/ha. Graded seed yield was recorded as the highest with 84 kg/ha (1772 kg/ha) compared to 72 kg/ha (1541 kg/ha). In terms of economic returns, the net monetary return per hectare was highest with a seed rate of 84 kg/ha (Rs. 2,30,098/-) compared to 120 kg/ha (Rs. 1,70,010/-) with benefit-cost ratio 4.03 and 2.85, respectively. It is concluded from the study that optimal seed rate for achieving maximum seed yield and improved seed quality in bold-seeded variety of chickpea is 84 kg/ha.
