Abstract

Adopting conservation agriculture with crop residue retention can enhance crop productivity, soil health and overall sustainability of soybean-wheat cropping system. Benefits of CA with crop residue application vary from location to location depending on management practices, agro-climatic condition and type of soil. However the effect of different levels of residue retention on soil properties and crop productivity in black soil of M.P. in soybean cropping system under conservation agriculture practices need to be studied. Keeping the above facts in view, a study was conducted during 2018-19 at ICAR- IISS, Bhopal and under this a experiment was carried out in randomized block design with four residue levels as treatments and six replications under soybean cropping system. So, the finding of the study indicate that Retention of 90% residue level in treatment T4 recorded significantly higher soil moisture content on dry weight and volume at 0-5 cm and 5-10 cm. With increase in levels of residues in soil after harvest of soybean crops OC of the soils under different treatments increased significantly. The highest SOC was recorded under treatment T4 (1.13%). Retention of different levels of residue significantly increased the soil available N, P & K status after harvest of soybean crops. Different residues level had significant effect on DHA. DHA, which indicates the microbial activity, was found to be increased with increasing levels of crop residues retention after harvest soybean crop.

Conclusion

The present study clearly showed that residue retention along with no tillage under conservation agriculture in Soybean-Wheat system improve physical chemical and biological properties of a deep black soil of central India and there by contributed positively in affecting growth parameter, yield attributing characters and productivity of both Soybean and Wheat crops.
