Abstract:
The farmer field study was carried out during 2016-17 at village Saida, Takhatpur Tehsil in Bilaspur district of Chhattisgarh to evaluate the “Long term effects of rice establishment methods on soil properties and rice productivity in vertisols of Chhattisgarh plain”. The trial was laid out in Randomized block design with twelve replication and three treatments under rice based cropping system in Vertisols. The study was focused on the effect of long-term rice establishment methods on rice productivity and nutrients uptake in vertisols were evaluated after harvest of rice crop. This study was undertaken to assess the rice productivity and nutrients uptake under various rice establishment methods. Nitrogen, Phosphorus and Potassium content in grain and straw were non significantly increased with transplanting method followed by broadcasting-biasi and direct seeded (Line Sowing) methods. The higher grain yield of rice was found in transplanted rice (4404 kg ha^-1) followed by broadcast-biasi (3825 kg ha^-1) and direct seeded rice (3417 kg ha^-1). The higher straw yield was recorded in transplanting method (4975 kg ha^-1) while the lower straw yield was recorded in direct seeded method (3904 kg ha^-1). The method of establishment plays an important role in growth development and yield of rice. Similar results were observed in nitrogen, phosphorus and potassium uptake by grain and straw.
