Crop intensification using short-duration cassava serves as an adaptation strategy promoting climate resilience. A two-year field experiment was carried out to assess the viability of intercropping short-duration cassava with pulse crops in a rice-based system. Rice var. Kanchana was initially planted, followed by short-duration cassava (var. Sree Vijaya and Vellayani Hraswa) intercropped with pulse crops such as green gram, black gram (var. Co-6) and soybean (var. JS-95-60), under two fertility levels. Intercropping Sree Vijaya or Vellayani Hraswa cassava varieties with black gram under reduced fertilizer level produced (25.94 t ha-1; 19.39%) yields similar to sole cassava (32.18 t ha-1). Growth attributes, biomass production and partitioning, crop growth rate and tuber bulking rate of cassava in this treatment matched sole cassava, particularly by the final growth phase. Tuber biochemical constituents remained unaffected. Thus, the combination of rice var. Kanchana followed by short-duration cassava var. Sree Vijaya + black gram var. Co-6 proved productive and feasible, while conserving half of the FYM and N and all P.
