Effect of biological fertilizer on the growth and nodules formation to soya bean (Glicine max (L.) merrill) in ultisol under net house conditions

Abstract

Present study was aim to assess the effect of various concentrations of biological fertilizers on the growth and nodules formation in soybean crop (Glicine max (L.) Merrill) in Ultisol under net house condition. Study was conducted under net house condition in the month of July to October 2014. Study was conducted in randomized block design (RBD) with six treatments and each treatment was replicated with 3 replications. The variables studied were plant height, stem diameter, root length, nodule diameter, nodule number, effective nodules number, fresh nodule weight, wet effective nodules weight, dry nodule weight and dry effective nodule weight. Results of study revealed that treatments of M-bio fertilizer at concentration of 12 ml per liter of water provide the highest growth such plant height as 44.65 cm, stem diameter as 0.86 cm and roots length as 24.49 cm. The treated soybean plant have 21.27 nodules and among these number of effective nodules are 16.63 pieces.

Response of Bacillus megaterium and Bacillus mucilaginosus Strains on Growth and Nutrient Uptake of Soybean

“…This might be due to higher availability and uptake of N, P and other nutrients by the crop and as these inoculations plays important role in improving availability of N and P. Seed inoculation with bio-inoculants also produce fungistatic and growth promoting substances which influenced the plant growth. Similar results were found by [15], [16] and [6].…”

Response of Combined Application of Nutrient Levels with Microbial Strains on Crop Growth, Nodulation and Yield of Soybean

“…Seed inoculation with bio-inoculants also produce fungistatic and growth promoting substances which influenced the plant growth. Similar results were reported by Sarawa and Arma [11], Mekki et al [12].…”
