The site of the experiment was ideal for common beans due to its silty clay loam texture that provided a medium level of soil organic carbon and readily available primary nutrients. The experiment was conducted in randomized block design (factorial) comprising of four type of tillage systems namely conventional (CT), rotary (RT), minimum (MT), and zero tillage (ZT) as the first factor. Two residue management practices, i.e., no residue (NR) and application of brown sarson residue (SR) were supplemented to all the tillage treatment as the second factor. The results revealed that seed yield in zero tillage was comparable to conventional tillage. Seed yield and biological yield was also increased in residue application. Resource use efficiency like nutrient-use efficiency and irrigation water-use efficiency was significantly higher with rotary tillage followed by conventional tillage. Contrary to nutrient use efficiency and irrigation water use efficiency, energy-use efficiency was significantly higher with zero tillage and rotary tillage irrespective of residue management. Residue application also increased the resource use efficiency of common bean. The effect of zero tillage and residue application on resource-use efficiency would advance after some extended period of the treatment application. |
