Effect of Fertility Levels and Weed Control Practices on Nutrient Uptake and Yield of Rainfed Barley in Eroded Soils of Central U. P.

摘要

An investigation was carried out to study the fertility levels and weed control practices in rainfed barley 'K560' at Kanpur during rabi season of 2004-05 and 2005-06. Application of 60 kg N + 30 kg P_2O_5 + 30 kg K_2O/ha brought about signficiantly highest grain and straw yield over other treatments. In adidtion, the N, P, K content as well as uptake by both grain and straw and net return were also more. Crop yield was better with inter-culture about 25 days after planting as compared to application of atrazine @ 1.0 kg a.i / ha (pre-emergence).
