Intercropping is considered a promising system for increasing crop productivity and land-use efficiency. A field study was conducted to evaluate the effect of different crop combinations of wheat-lentil on the productivity of wheat (Triticum aestivum L.) and lentil (Lens culinaris) and land-use efficiency under two tillage practices in Minjar district during 2015-2017 cropping seasons. The experiment was carried out using split-plot design with three replications. The treatments consisted of two tillage practices (conventional and minimum tillage) assigned as the main plot and five wheat-lentil intercropping combinations (1:0, 1:1, 2:1, 1:2 and 0:1) assigned as the subplot. The tillage practices and intercropping had a significant effect on the growth parameters of wheat and lentil. Minimum tillage increased growth parameters for wheat, but reduced growth parameters for lentil. The yield of wheat was non-significantly affected by tillage practices, but the yield of lentils was significantly affected by tillage systems. A higher yield of lentil (1546 kgha-1) was obtained in conventional tillage as compared to minimum tillage practices. Intercropping combination had a significant effect on both the growth and yield parameters of both crops. The highest yield of wheat (2932 and 2982 kgha-1) was recorded in sole wheat (1:0) and 2:1 wheat-lentil combination, while the highest yield of lentil (1575 kgha-1) was obtained in sole lentil (0:1). Among intercropping combinations, 2:1 wheat-lentil gave the highest LER, ATER, and MAI values. Therefore, 2:1 wheat-lentil intercropping combinations were found suitable for higher productivity and production of component crops, and the intercropping system of wheat-lentil in any of the combinations found to be more profitable and productive compared to sole wheat and lentil.
