Response of Bacillus megaterium and Bacillus mucilaginosus Strains on Yield and Quality of Soybean

Abstract

At present due to continuous use of phosphatic and potassic fertilizers a deposits of these nutrient have increased in the soil of studied area, and Bacillus megaterium and Bacillus mucilaginosus solubilize/mobilize P and K in the soil, thus, for increasing yield and quality of soybean, an experiment was planned with the aim to investigate the response of Bacillus megaterium and Bacillus mucilaginosus strains on yield and quality of soybean [Glycine max (L.) Merrill.] at All India Coordinated Research Project (AICRP) on Integrated Farming System Research at College of Agriculture, Indore, Madhya Pradesh, India during kharif, 2019 & 20. The research was conducted in randomized block design (RBD) with 8 treatments, viz. Control with 75% RDF (T1), Control with 100% RDF (T2), 75% RDF with Bacillus megaterium and Bacillus mucilaginosus strainsas seed treatment (T3), 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strainsas seed treatment (T4), 75% RDF with Bacillus megaterium and Bacillus mucilaginosus strainsas foliar application at 30 and 45 DAS (T5), 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strainsas foliar application at 30 and 45 DAS (T6), 75% RDF with Bacillus megaterium and Bacillus mucilaginosus strainsas seed treatment + foliar application of Bacillus megaterium and Bacillus mucilaginosus strainsat 30 and 45 DAS (T7) and 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strainsas seed treatment + foliar application of Bacillus megaterium and Bacillus mucilaginosus strainsat 30 and 45 DAS (T8). The seed yield (1139 kg ha-1) of soybean increased to the tune of 14.26 and 19.72 per cent with application of 100% RDF with Bacillus megaterium and Bacillus mucilaginosus strainsas seed treatment + foliar application of Bacillus megaterium and Bacillus mucilaginosus strains (T8) at 30 and 45 DAS compared to control (786 kg ha-1). Among all the treatments, yield attributes such as pods count plant-1 (29.66), seeds count pod-1 (3.36) and seed yield plant-1 (13.17) were observed highest with T8 at 30 and 45 DAS.

Effect of Micronutrients and Biofertilizer Treatments on Yield and it`s Attributes of Coriander (Coriandrum sativum L.) cv. RCR-41

“…In addition, biofertilizer enhances plant growth by synthesising phytohormones, fixing nitrogen, reducing root membrane potential, synthesising enzymes like ACC deaminase that regulate plant hormone levels, and solubilizing inorganic phosphates and mineralizing organic phosphates, thereby making phosphates accessible to plants. Findings are in accordance with those of [12]. The treatment further exhibited the highest test weight, and the increased seed weight may be linked to improved mineral utilization and enhanced photosynthesis.…”

“…Biofertilizers, viewed as more cost-effective, environmentally friendly, and sustainable, are expected to play a prominent role when used in conjunction with inorganic fertilizers [9,10] Despite their immense potential, the performance of biofertilizers, including Azotobacter, PSB, and KSB, can be inconsistent in practice [11] These biofertilizers contribute significantly to nitrogen (N) and phosphorus (P) availability, enhancing plant resistance to water stress [12]. Considering the above information, this field experiment aims to assess the impact of different micronutrients and biofertilizers on coriander yield parameters.…”
