| dc.description.abstract | A field experiment entitled “Evaluation of cowpea varieties under different irrigation schedules during summer season” was carried out during summer season, 2022 at the Research area of Forage Section Research Farm, Department of Genetics & Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University. The experimental treatment consisted of combination of three irrigation schedules viz. at 7, 11 and 15 days interval and four cowpea varieties viz. RC 101, GC 1601, PGCP 24 and HC 46. The experiment was laid out in split plot with three replications on sandy loam soil having pH 7.9, EC 0.32 dS m⁻¹ and organic carbon 0.46% with low available nitrogen (125 kg ha⁻¹), medium phosphorus (13.5 kg ha⁻¹) and medium potassium (290 kg ha⁻¹) status. Significantly highest plant height (142 cm), dry matter accumulation (16.44 g) and leaf area index (9.75) were recorded at harvest under irrigation scheduled at 7 days interval. Maximum no. of pods per plant (22.28), pod length (13.38), no. of seeds per pod (13.08), seed index (10.15) and seed yield (904 kg/ha) was recorded under irrigation at 11 days interval which was at par with irrigation at 15 days interval but superior over 7 days irrigation interval. Seed yield at irrigation schedule 11 days interval was 3.6 % and 36 % higher as compared to seed yield under 15 and 7 days interval. Maximum gross returns (59369 ₹ ha-1) and net returns (29.579 ₹ ha-1) were fetched under irrigation scheduling at 11 days interval but highest BC ratio (1.93) was fetched under irrigation schedule at 15 days interval. Among varieties, maximum seed yield (937 kg/ha), gross returns (61809 ₹ ha-1), net returns (29353 ₹ ha-1) and BC ratio (1.93) was fetched in variety GC 1601 which was at par with variety PGCP 24 and superior than variety RC 101 and HC 46. | |
