The effects of different ırrigation levels and arbuscular mycorrhizal fungi (amf), photosynthesis activator, traditional fertilizer on yield and growth parameters of dry bean (phaseolus vulgaris l.) in arid climatic conditions

Abstract

A field experiment has been conducted to determine the effects of different irrigation water and AMF (Arbuscular Mycorrhizal Fungi) biofertilizer, photosynthesis activator and traditional fertilizer dry bean (Phaseolus vulgaris L.) on yield and growth parameters in Nevsehir Province of Turkey in 2015. The experiment has been carried out using three replications in a split plot design with three different irrigation types as main plots and AMF biofertilizer (ERS), photosynthesis activator (Multigreen-Mg), traditional fertilization (TF-Control), ERS + Mg, ERS + TF and TF + Mg applied as subplots. The number of pods per plant, the length of pods, the number of grains per pod, the weight of grains per plant, the yield of grains, 1000 seed weight, the number of grains per plant, protein yield, arbuscular mycorrhizal fungi rate have been evaluated as yield and growth criteria in the study. In the experiment, as well as the treatment x irrigation interaction, the plant height, pod number per plant, pod lenght, grain number per pod, grain weight per plant, grain yield, 1000 seed weight, grain number per plant, protein rate/grain, protein yield, root weight and AMF colonization parameters, were the other studied properties that were found to be significant. The results obtained were 877.6 mm for I100 irrigation treatment, 512.2 mm for I50 irrigation treatment and 40.19 mm water for I30 irrigation treatment. Regarding the growth parameters of dry bean, the highest PH was in ERS + Mg (67.66 cm), the lowest PH was in ERS (54.33 cm); In I50, the highest Plant Height (PH) was in ERS + Mg (65.66 cm), the lowest PH was in TF-Control (53.00 cm); and in I30, the highest PH was in TF-Control (50.66 cm), and the lowest PH was again in ERS + Mg (44.33 cm). For protein yield (PY) value, ERS + Mg, ERS + TF, TF + Mg have been placed in the same group, in I100 and I50 irrigation treatment. The highest value was ERS + TF (34.90 kg da−1) in I100, The lowest value was TF-control (19.90 kg da−1) in I30 irrigation treatment. In terms of mycorrhiza colonization ratio, ERS has been ranked first in all irrigation treatments, while the highest mycorrhiza colonization has been observed in I30 irrigation treatment (26.30%). ERS was followed by ERS + Mg (23.33%). As expected, the lowest mycorrhiza colonization ratio in all irrigation treatments have been observed in TF-control treatment, while the highest mycorrhiza colonization ratio has been respectively observed in I30 and I50 irrigation topics. The highest root weight (RW) in I100 irrigation treatment was observed in ERS (15.06 g plant−1) and it was observed in ERS (19.05 g plant−1; 26.30 g plant−1) in I50 and I30 irrigation treatments. The lowest RW in all irrigation treatments has been observed in TF + Mg (4.43 g plant−1, 6.40 g plant−1, 10.26 g plant−1), respectively.
