The effect of biofertilization and organic fertilization and the interaction between them on the yield characteristics and components of the mung bean plant Vigna radiata L.

Abstract

A field experiment was conducted in the fall season of 2022 in the village of Aday in Baquba District - Diyala Governorate, on the mash plant. Vigna radaita a local vegetable cultivar in clay soil in order to study the effect of biofertilization with Azotobacter chroococcum and Mycorhiza fungi (Glomus mosseae) and organic fertilization with humic acid and the interaction between them on the vegetative characteristics of the mung bean plant. The experiment was carried out according to the randomized complete block design (R.C.B.D) and with three replications. It included two factors, the first was biological fertilization, which included four treatments, namely (without addition, the addition of Azotobacter, the addition of Mycorrhiza, and the addition of Azotobacter + Mycorrhiza) and the second factor was organic fertilization, which included four concentrations of humic acid 0 and 3 And 6 and 9 ml.l-1. The following are the most important results that were reached: - The superiority of biofertilization treatment by adding Azotobacter and Mycorrhizae in the yield and its components, such as the number of pods, the weight of 1000 seeds, the yield of one plant, the overall yield, obtained, Azolobacter and mycorrhizae were introduced to the biofertilization process., 130.83 pods.plant-1, 29.26 gm., 35.57 g.m. plant-1, 2341.08 kg.h-1. - The treatment of organic fertilization with humic acid at a concentration of 9 ml.L-1 was superior in giving it the highest mean in the number of pods, the weight of 1000 seeds, yield per plant, overall yield, which reached 127.14 pod.plant-1, 27.76 gm., 36.2 gm. plant-1, 2221.2 kg.h-1.
