Abstract :
In today's world, the reduction of soil fertility is the main biophysical limitation to improve yield of crops production and thus it is considered as a potential threat to achieve food security. In order to investigate the efficiency of agrarian inputs in different cropping systems for the sustainable production of red bean, this experiment was conducted as factorial layout based on a randomized complete block design with three replications during growing season of 2020-2021 and 2021-2022 at the experimental field of beiranshahr city of Khorramabad in Lorestan Province, in the west of Iran. Five cropping systems with different levels of input use included Ecological, integrated, low input, medium input and high input and four red bean cultivars included Ofogh, Dadfar, Goli and Yaghot. The results showed that the highest average of Relative growth rate (RGR) in Yaghot variety in high input cropping system; The highest average of net assimilation rate (NAR) in Dadfar variety in high input cropping system; The highest average of leaf area index (LAI) in Dadfar variety in the integrated cropping system; The highest average of crop growth rate (CGR) observed in Dadfar variety in the integrated cropping system and the highest average of Total dry matter accumulation (TDM) was observed in the Yaghot variety in the integrated cropping system. The highest seed yield observed in Yaghot cultivar in integrated cropping system (3092.4 kg/ha-1). seed yield in Yaqut cultivar increased by 31.01, 15.80 and 21.49 percent, respectively, compared to Ofogh, Dadfar and Goli cultivars in the integrated cropping system. Obtained results of this experiment showed that the integrated cropping system can bring the physiological growth indices and agricultural characteristics of red bean cultivars to the highest level compared to the ecological, low-input and medium-input cropping systems for Increase productivity and profitability in the farm.
