Abstract

Rising cost of fuel and availability of effective package of practices for conservation tillage have now redefined the tillage practices in India in recent past. Hence an experiment was carried out with pigeonpea [Cajanus cajan (L.) Millsp.] with an objective of minimizing the inputs originating from non-renewable energy resources like fertil- izer and diesel on a permanent site with 5 main-plot treatments, viz. zero-till (ZT) flat bed (FB) and zero-till (ZT) raised-bed (RB), in that with or without residue retention and conventional tillage (CT) practice, subplots with re- duced recommended fertilizer dose (RDF). Resource-conservation practice of ZT-RB with crop-residue retention (CRR) along with 100% RDF recorded higher soil-moisture content at all the growth stages than the other prac- tices, which helped plant to produce higher growth characters and SPAD readings and these in turn increased yield parameters like pods, seed weight/plant. Finally, seed yield (1.29 t/ha) and straw yield (4.61 t/ha) were signifi- cantly higher in ZT-RB with CRR than the other practices. Energy and economics showed that the ZT-RB with CRR along with RDF incured lower input energy and cost of cultivation. The gross (`73,104/ha) and net returns (`49,992/ha) and seed output energy (19,612 MJ/ha) were higher in ZT-RB with CRR along with 100% RDF, but remained at par with 75 and 50% RDF. Looking at sustainable yield index, energetic and economics in resource- conservation practice of ZT-RB with CRR, the nutrient requirement can be reduced up to 50% RDF.
