Abstract:
A field trial was conducted during the rabi season of 2014-15 at Research Farm area of CCS Haryana Agricultural University, Hisar. In the study two seed rate (87.5 and 100 kg ha-1) and three spacing (18, 20 and 22 cm) were used in main plots and four nitrogen levels (60, 75, 90 and 105 kg ha-1) in sub plots with three replication under split plot experimental design. The dry matter accumulation as well as grain yield improved significantly with the use of 100 kg seed rate as compared to 87.5 kg ha-1. The nutrients content were statistically similar under both seed rates. However, the NPK uptake of grain as well as total uptake of N and P increased significantly with 100 kg seed rate as compared to 87.5 kg ha-1. The dry matter accumulation was significantly higher under 18 cm row spacing in comparison to both 20 and 22 cm spacing. Row spacing had no significant effect on NPK content of grain and straw of malt barley. However, total NPK uptake and grain yield with 18 cm row spacing was significantly higher than 22 cm but was at par to 20 cm. Dry matter accumulation, N content and total NPK uptake increased significantly up to 90 kg N ha-1. Total NPK uptake was highly and positively correlated with dry matter accumulation having determination factor of 0.982, 0.989 and 0.989, respectively. Similarly, the dry matter accumulation was positively correlated with quality parameters viz. husk and protein content whereas it was negatively correlated with starch and malt content.
