Influence of sowing times, seed rates and row spacings on physiological studies of barley (Hordeum vulgare L.)

Abstract

The field experiment was conducted at the Regional Research Station (Bawal) Department of Agronomy, CCS Haryana Agricultural University, Hisar (India) during the year 2015-16 and 2016-17. To evaluate the optimum sowing time, seed rate and row spacing on physiological studies of barley. The experiment was conducted with split-split plot design replicated three times. Treatments consisted of four dates of sowing viz; D1 (last week of October), D2 (1st week of November), D3 (2nd week of November) and D4 (3rd week of November) and two seed rates viz; recommended and 110% of recommended was kept as main plot and three row spacings viz; (17.5 cm), (20 cm) and (22.5 cm recommended) was kept as sub plot. The received results that physiological studies viz; LAI, LAD, CGR, NAR and RGR were significantly enhanced under D1 (last week of October) sown crop than other sowing dates. Physiological studies were significantly superior under (20 cm) row spacing over the rest row spacing and not significant effects of that two seed rates. The worthier physiological studies were figures under D1 (last week of October) with (20 cm) row spacing.
