Abstract :
To investigate the impact of agricultural management practices on yield and yield components of bean, a split-plot factorial design experiment with randomized complete blocks and three replications was conducted in Aligudarz city Iran during (2019 and 2020). The tested factors include irrigation (furrow and drip), as the main factor and the combination of cultivar treatments (Akhtar and Yaghout) and fertilizers (NPK in the quantity required by the plant according to the bean fertilizer table, application Bio-chemical fertilizers and application of pure nitrogen) as secondary factors. Results showed that average seed yield increased significantly under drip irrigation (3282.3 kg/ha) compared to Furrow irrigation (2319.2 kg/ha) and the difference (41.52 %). The highest seed yield and the efficiency of remobilization of dry matter were obtained of Yaghout cultivar with combination of Bio-chemical fertilizers. The lowest seed yield was in Akhtar cultivar using chemical NPK fertilizers. All cultivars showed significant increase in yield under drip irrigation and combination of Bio-chemical fertilizers. Based on the results of the two-year composite analysis of the data, Yaghout variety and the combination of biological and chemical fertilizers, the highest seed yield (3777.6 kg/ha), biological yield (9030.6 kg/ha) and efficiency of remobilization of dry matter (22%) compared to Akhtar variety in the treatment. Nitrogen-phosphorus-potash fertilizers were the best treatments (89.9%, 82.6% and 83.3% respectively).
