The main production restriction in Nepal is a shortage of nitrogen and phosphorus-based fertilizers. In addition, the excessive use chemical fertilizers to increase rice alters soils’ physicochemical biological qualities. effective application biofertilizers obtained from beneficial microorganisms on demand for increasing agriculture as well maintaining soil health sustainably. experiment was c...

Given the hypothesis that co-inoculation with plant growth-promoting bacteria (PGPB) enhances beneficial effects of Rhizobium tropici greater mineral nutrition, optimizes biological nitrogen fixation and reduces use fertilizers in bean plants, objective this research was to evaluate synergistic associated Azospirillum brasilense, Bacillus subtilis, Pseudomonas fluorescens their combinations, on...

There are increasing applications of diazotrophic rhizobacteria in the sustainable agriculture system. A field experiment on young immature oil palm was conducted to quantify the uptake of N derived from N₂ fixation by the diazotroph Bacillus sphaericus strain UPMB-10, using the ¹⁵N isotope dilution method. Eight months after ¹⁵N application, young immature oil palms that received 67% of standa...

Schizolobium parahyba var. amazonicum (Huber ex Ducke) occurs naturally in the Brazilian Amazon. Currently, it is being planted extensively because of its fast growth and excellent use in forestry. Consequently, there is great interest in new strategies to increase wood production. The interaction between soil microorganisms and plants, specifically in the roots, provides essential nutrients fo...

In our endeavor to improve the nitrogen fixation efficiency of a soil diazotroph that would be unaffected by synthetic nitrogenous fertilizers, we have deleted a part of the negative regulatory gene nifL and constitutively expressed the positive regulatory gene nifA in the chromosome of Azotobacter chroococcum CBD15, a strain isolated from the local field soil. No antibiotic resistance gene or ...

Abstract In order to study the effect of different soil amended and biological fertilizers on accumulation nitrogen phosphorous in wheat grain some physiological morphological characteristics wheat, this experiment was performed as a split factorial arranged randomized block design with 32 treatment three replication for 2 years. The treatments included mycorrhiza inoculation main factor (witho...

Agrochemical is evolved by the contraction and combination of words agricultural and chemical, and is a generic term used for the various chemical products typically used in agriculture. Agrochemicals essentially help in intensifying crop production and to reduce the effects of pests and parasites on farm animals. Agrochemical basically refers to the broad range of pesticides and fertilizers. A...

Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be the differentiation of crops and vegetable grown under different farming systems. The objective of this study was to compare nitrogen and carbon isotope composition of organic fertilizers and manur...
