Integrated Effect of Rhizobium and Azotobacter Cultures on the Leguminous Crop Black Gram (Vigna mungo)

Abstract

A pot experiment was performed to evaluate the integrated effect of Rhizobium and Azotobacter sp. on the plant growth, nodule appearance, no of leaf, shoot length, root length, chlorophyll contents and carbohydrate content in .2) and chlorophyll content (1.3 mg/g) and reducing (867.4 µg/g) and non-reducing sugar (1905.5 µg/g) content per plant biomass respectively. The Azotobacter and Rhizobium sp. have friendly associations and they have different physiology and habitat. Therefore, they help plant growth promotion by them own system. Therefore, such combination can be recommended for field application for sustainable agriculture. Excessive application of chemical fertilizers causes environmental and economic problems; hence the use of PGPR and Rhizobium bacteria can be acceptable due to cut contribution expenditure, increase in grain yield and environmental friendly.

Effect of biofertilizers on growth, photosynthetic and biochemical parameters of tomato (Lycopersicon esculentum Mill.)

“…This work agrees with the work of Rahmani et al (2008) who indicated that nitrogen is the most important element in protein synthesis and its increase in optimum conditions increases the amount of protein. Also the obtained findings are in line with Tiwari (2017) who reported an increment of total sugar and carbohydrates content with the mixed culture of Azotobacter and Rhizobium sp. treatment (T 4 ) increased reducing and non-reducing sugars quantity.…”

Effect of Iron, Molybdenum and Rhizobium on Growth, Yield Attributes and Yield of Summer Groundnut (Arachis hypogaea L.) in Loamy Sand Soil

“…It might be due to the fact that the Rhizobium population in the experimental field was low and seed inoculation with Rhizobium increased the number of Rhizobium in the field which is involved in nitrogen fixation. Similar findings were also reported by Tiwari et al [13].…”

Influence of Pre Sowing Seed Treatments with Biofertilizers and Plant Growth Regulators on Growth, Yield and Yield Attributing traits of Field Pea (Pisum sativum L.) Var. Rachna

“…Additionally, azospirilla do not significantly excrete ammonium during diazotrophic development. Other factors, such as the synthesis of chemicals that encourage plant development and an increase in the rate of mineral uptake by plant roots, have also been considered to explain the improvement in plant output and may even be more significant in determining the plant response [9,10].…”
