Abstract
To improve the sustainability of agriculture, one way is to increase the variety of ecosystems by a mixture of species or cultivars. To evaluate the impact of mixed cultivation of sesame and bean on yield, yield components, and weed control, an experiment was done in a field in Jiroft, Iran, in 2015 which was characterized as follows: with a randomized complete block design, three replications and different ratios of sesame and bean based on increase and alternative methods. The treatments included 1: 100% sesame, 2: 100% beans, 3: 50% sesame + 50% beans, 4: 75% sesame + 25% beans, 5: 25% sesame + 75% bean, 6: 100% sesame + 100% beans, 7: 100% sesame + 50% beans, 8: 50% sesame + 100% beans. According to results, different cultivation systems except for 100 seed weight had different effects on height, stem diameter, number of lateral sprouts, number of capsule, sesame 1000 seed weight, number of pod, number of grain per bean pod, grain yield, biological and harvest index of the mixed crops. Max grain and biological yield of the mixture decreased at different ratios due to competing of each crop for more food resources. The highest yield was gained with pure cultivation. Regarding the total profitability, the mixed cultivation was superior to the pure one. About weed control, the former was superior. The lowest temperature and soil humidity was obtained with the mix models. Max temperature at the top of sesame’s leaves resulted from the 100% sesame + 50% bean treatment. Max and minimum temperatures of the top part for sesame’s leaf were related to 100% sesame + 100% beans, and pure planting respectively. Considering bean alone, max and minimum temperatures at the top were related to pure, and 100 sesame + 50 bean respectively.
