Abstract

A field experiment in the form of split-plot factorial in the form of randomized complete block design with 3 replications was carried out in 2017-1398 and 2018-1399 in Aliguderz. The test factors include irrigation (atmospheric, stack and drip) in the main plots and the combination of varieties (Akhtar and Yakut) and fertilizer (1- NPK based on soil test results 2- combination of bio-chemical fertilizers 3- pure nitrogen in the amount of 30 kg per hectare in each of the stages of three and five leaves of growth) were placed in sub-plots. The results of trait analysis showed that the highest and lowest efficiency of dry matter transfer (22 and 9 percent) was obtained from Yakut cultivar with NPK application in 2018 and from Akhtar cultivar with bio-chemical fertilizers application in 2019, respectively.The highest share of grain yield from current photosynthesis was given to the ruby variety with the use of bio-chemical fertilizers in both years of the experiment (76.6%). The highest amount of accumulation capacity of photosynthetic materials was obtained in Yaghout variety under drip irrigation (330.584 mg). Two parameters of seed yield contribution from current photosynthesis and photosynthetic material accumulation capacity had the greatest role in increasing seed yield due to very high correlation (0.66% and 0.99%, respectively). Finally, the results showed that the three-way integration of Yaghout variety, the combination of bio-chemical fertilizers and drip irrigation were the best treatments due to obtaining the highest grain yield in beans.
