Crop Intensification through Short Duration Stress-Tolerant Rice Varieties with Green Gram for Fostering Agricultural Resilience and Sustainability

Abstract

Rice stands as a critical cornerstone in the pursuit of food security due to its unparalleled significance as a staple crop for billions of people worldwide. Rice in India, is cultivated within diverse cropping systems that harness the nation's rich agro-climatic variations. Eastern India has emerged as a significant contributor to the country's overall rice production. Nevertheless, most of the existing cropping systems of rice in this region suffer from some drawbacks, primarily due to monoculture practices and limited crop diversity. An experiment was conducted in the Eastern Indian State of Odisha to evaluate the efficiency and profitability of promoting a rice-green gram-rice cropping system. The experiment consists of two major interrelated interventions viz., awareness regarding short-duration stress-tolerant rice varieties (STRV) and the introduction of the new crop for higher economic returns. Varietal awareness programs were organized before the onset of the wet season of 2020 and the potential benefits of cultivating STRV over the popular traditional cultivars were communicated to the target farmers, besides advocating the rice-green gram-rice cropping system. The study employed a field experiment design to compare the performance of existing and new cropping systems. The impact evaluation was carried out after recording the comments of the farmers followed by a thorough comparison between the new and existing cropping systems. The available evidence suggests that the introduced short-duration STRVs are better than the already existing varieties and have the potential to change the cropping system of the region. The most desirable trait of these varieties as reported by the farmers is their short maturity duration. The results do unequivocally demonstrate the superior performance of the new cropping system over the existing system in terms of crop yield, diversification, and profitability. This remarkably underscores the potential of the new system to address food security challenges and enhance agricultural productivity.
