Abstract:
A field investigation was undertaken at Research Farm, Department of Agronomy, CCS Haryana Agricultural University, Hisar. The aim of the experiment was to study the effect of different agronomic practices on heat unit requirement and also to quantify their relationship with growth parameters, malt and protein yields of two-rowed malt barley. The study comprised of two levels of seed rate (87.5 and 100 kg ha^-1) and three spacings (18, 20 and 22 cm) in main plots and four levels of nitrogen (60, 75, 90 and 105 kg/ha) in sub plots. The treatments were laid out in split plot design with three replications. The dry matter accumulation, LAI and number of tillers at all stages as well as grain, malt and protein yield improved significantly with the use of 100 kg seed rate, 18 and 20 cm row spacing and 90 kg N/ha. However, GDD, PTU and HTU were significantly higher with the application of 105 kg N/ha as compared to lower levels of nitrogen. Dry matter accumulation, LAI, number of tillers, grain, malt and protein yield had positive and strong correlation with agro-meteorological indices.
