Description |
Tillage and surface management plays a crucial role in sustainable management of soil and water resources. Therefore the influence of various tillage practices and straw mulching with rice straw @ 10 tonnes/ha on the soil edaphological factors and hence on the growth and yield of chickpea crop was studied in a rice-chickpea cropping system at the Research farm, IGKV, during rabi 1994-95 with the chickpea variety "J.G.-74". The crop was sown on 7th Nov'1994 and harvested on 20th March, 1995. Three tillage treatments with and without rice straw mulch application and zero tillage treatments were compared in R.B.D. with four replications. The different tillage treatments (Broadcasting of chickpea seeds + cross ploughing + planking, Broadcasting of chickpea seeds + cross ploughing + discing + planking and ploughing + discing and planking followed by line sowing) were found to have no significant differences between them in respect of their performance whereas a significant difference was obtained between the tillage treatments and the zero tillage treatment. Grain yield, total dry matter yield and •53 other yield attributing characters as well as the crop growth were enhanced by the tillage treatments. Soil compaction was more under zero tillage treatment than under the tillage treatments, thus resulting in poor plant growth by restricting the root penetration to the deeper soil layers and the water movement to the roots, whereby resulting in a low yield as compared to other tillage treatments. Thus tillage treatments by providing a congenial physical environment for the various activities of the plant growth, proper aeration and water retention helped in resulting in a good crop production as against zero tillage. Rice straw mulching also showed a beneficial effect on plant growth and yield. Mulching helped in reducing the surface soil temperature where by preventing excessive evaporation losses from the surface. Thus it can be concluded that the treatment, broadcasting of seeds followed by ploughing, discing and planking together with mulching had more favourable effect on the soil edaphological and physical properties as well as on growth and yield of chickpea after transplanted rice, while the treatment with poorest performance was found to be the zero tillage (direct drilling of seeds between the standing rows of rice straw). |
