Abstract:

A field experiment was conducted in kharif, rabi and summer seasons of 2014-15 to 2015-16 at ICAR-IARI, New Delhi to study the residual effect of crop residue (CR) and potassium (K) management on greengram productivity, soil and canopy temperature depression (CTD) in maize and wheat under zero tillage maize-wheat-greengram cropping system. The experiment was laid out in split plot design with four CR levels (0, 2, 4 and 6 tha-1) and five K levels [0, 50%, 100%, 150% RDK (recommended dose of K) and 50%RDK+Potassium solubilizing bacteria, KSB]. Greengram was sown as summer season crop to study the residual effect of treatments imposed for maize and wheat crops without any fertilization in greengram. Results revealed that greengram seed yield was significantly higher (46.93-51.02%) with4-6.0 tha-1 CR as compared to no CR. Similarly, 50% RDK + KSB recorded significantly higher grain yield over No K (56.52%-63.15%). Furthermore, soil temperature non-significantly decreased in maize and increased in wheat with 4.0-6-tha-1 CR compared to no residue applied plot throughout the growing period. However, among residue management practices highest value of CTD was observed with 6-4.0 tha-1 CR. K management practices did not influence much on soil temperature and CTD except KSB treated plot. Therefore, CR retention at 4-6.0 tha-1 and application of 50% RDK + KSB could have a positive residual impact on summer greengram productivity enhancement by regulating soil temperature with favourable CTD in maize and wheat crops under conservation agriculture-based maize-wheat-greengram cropping system.
