Abstract:
The field experiment was conducted at District Seed Farm, ‘A-B’ block, of Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India, during two subsequent rabi (winter) seasons (November – March) of 2018-19 and 2019-20, to evaluate the growth rate and seed yield of field pea genotypes under varying seed rates at New Alluvial Zone of West Bengal. The experiment was laid out in a split plot design with two different seed rates (80 kg ha-1 & 100 kg ha-1) and five different genotypes (HUDP 15, SKNP 04-09, IPF 16-13, VL 42, TRCP 8) as primary and subplot factors respectively. Based on pooled data of two-year investigations, higher seed rate treatment (seed rate 100 kg/ha) always recorded a superior growth rate compared to lower seed rate treatment (seed rate 80 kg/ha). Still, contradictorily, lower seed rate recorded higher seed yields. This implies optimum plant population is a crucial practice to obtaining higher seed yield. In the case of variable genotypes, the highest CGR has been observed in SKNP 04-09 genotype during the interval of 60-90 DAS, and the highest seed yield was recorded in the case of IPF 16-13 genotype. The combination of genotype IPF 16-13 and HUDP 15 along with a seed rate of 80 kg/ha are economically profitable options for better production in terms of quality and quantity for cultivation in the New Alluvial Zone of West Bengal.
