ThesisItem Open Access Response of barley to vermicompost and fertlizer levels under alternate furrow irrigation method(Chaudhary Charan Singh Haryana Agricultural University, 2022-12) Abhishek; Thakral, S.K.The present study entitled “Response of barley to vermicompost and fertilizer levels under alternate furrow irrigation method” was carried out at Agronomy, Research Farm of CCS Haryana Agricultural University, (Haryana) during the winter, 2021-22. The experiment was conducted in a split-plot design with two vermicompost level i.e., vermicompost @ 1.5 t ha-1 and vermicompost @ 3.0 t ha-1, two irrigation method i.e., every furrow irrigation and alternate irrigation method as the main plot treatments and three fertilizer levels at N40P20, N60P30 and N80P40 kg/ha as subplot treatments and replicated three times. Experiment was laid out in split plot design with three replications. Based on the research investigation, it was found that vermicompost levels, method of irrigation and fertilizer levels have significant effect on growth, phenology, yield attributes, yield and economics of barley. Among the vermicompost levels, Vermicompost at 3.0 t ha-1 recorded significantly higher grain yield (4721 kg ha-1), straw yield (6032 kg ha-1 ), net return (78274 ha-1 ) and B:C (2.11) which were 11.0, 10.56, 12.41 and 1.44 per cent higher than vermicompost at 1.5 t ha-1, respectively due to higher yield attributes i.e. number of effective tillers (120.1), spike length (7.9 cm), number of grains per spike (41.1) and 1000-grain weight (38.70) than vermicompost at 1.5 t ha-1, respectively. Methods of irrigation, Every furrow irrigation recorded significantly higher grain yield (4842 kg ha-1), straw yield (6406 kg ha-1), net return (84837 ha-1 ) and B:C (2.24) which were 17.15, 26.08, 25.66 and 12.66 per cent higher than alternate furrow irrigation, respectively due to higher yield attributes i.e. number of effective tillers (120.5), spike length (7.9 cm), number of grains per spike (40.7) and 1000-grain weight (38.50) than alternate furrow irrigation, respectively. Among fertilizer level, application of N80P40 recorded significantly higher number of effective tillers (119.6), spike length (8.0 cm), number of grains per spike (41.2) and 1000- grain weight (38.60), grain yield (4842 kg ha-1), straw yield (6406 kg ha-1), net return (80418 ` ha-1) and B:C (2.18) over fertilizer level N40P20. Application of N80P40 closely followed by application of N60P30 and application of N60P30 also recorded similar values of above parameters.
