Effect of different nitrogen level and rice straw incorporation on the productivity of Barley (Hordeum vulgare L.) in south-west punjab

The field experiment entitled Effect of different nitrogen levels and rice straw incorporation on growth and Productivity of Barley (Hordeum vulgare L.) in south-west Punjab was conducted during the rabi season of 2017-18 at Research Farm of Guru Kashi University, Talwandi Sabo, Bathinda (Punjab). The trail was laid out in split plot design with four nitrogen levels viz., 0 kg N/ha (N0), 40 kg N/ha (N1), 60 kg N/ha (N2) and 80 kg N/ha (N3) in main plot and two levels of rice straw incorporation viz., Control (S0) and 10 tonnes/ha (S1) in sub plot. The results showed that the 80 kg N/ha recorded maximum plant height (88.9 cm), dry matter accumulation (107.4 q/ha), number of effective tillers/m2 (275.1), ear length (17.9 cm), number of grains per ear (59.8) and test weight (50.4 g), grain yield (40.7 q/ha), straw yield (75.6 q/ha) and harvest index (35.00%) than other nitrogen levels. Similarly, application of rice straw incorporation@10 tonnes/ha recorded higher plant height (85.4 cm), dry matter accumulation (98.1 q ha-1 ) and yield attributes i.e. number of effective tillers/m2 (263.8), ear length (18.0 cm), number of grains/ear (57.9) and test weight (50.8 g) as compared to control. | Effect of different nitrogen level and rice straw incorporation on the productivity of Barley (Hordeum vulgare L.) in south-west punjab
