The present work was conducted to find out the effect of biofertilizer formulated with four species of bacteria (two species of Azotobacter and two species of Lysobacter) and zinc sulphate. Field experiments with mustard plant were conducted to study the effectiveness of soil application of zinc sulphate and biofertilizer at 0, 10, 20, 30, 40, 50 days after sowing. Plant height and condition of...

BACKGROUND AND PURPOSE Intensive agriculture is practised in Taiwan, and compost application is very popular as a means of improving the soil physical properties and supplying plant nutrition. We tested the potential of inoculation with thermotolerant microorganisms to shorten the maturity and improve the quality of biofertilizer prepared by composting. METHODS Thermotolerant microorganisms w...

The objective of this study was to develop a simple and cost-effective method to produce biofertilizer using agro-wastes. There were five types of agro-wastes being used in this study. They were wastes from watermelon, papaya, pineapple, citrus orange, and banana. Solidstate fermentation method was used to produce biofertilizer, which was then applied into vegetable plantation. Physical propert...

Two field experiments were carried out during the summer seasons of 2000 and 2001, at the Experimental station Farm, Faculty of Agriculture, Alexandria University, at Abies, to investigate the response of potato plants cv. Alpha, to two biofertilizer types (Nitrobein and Halex-2) under four varying percentages NPK; 25%, 50%, 75% and100% from the commercial recommended rates (180-60-96 Kg N-P-K ...

Biofertilizers are used to improve soil fertility and plant production in sustainable agriculture. However, their applicability depends on several environmental parameters. The aim of our study was to evaluate the effect of free-living bacteria containing fertilizer on the growth of cucumber (Cucumis sativus L. cvs. Delicates) under aluminium (Al) stress. Different responses to Al stress of cuc...

Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...

A field experiment was conducted at the Experimental Farm of the Faculty of Agriculture, South Valley University at Qena on sandy soil to study the effect of integrated nutrient management (INM) on productivity and grain protein content of wheat. Seven different treatments with three replications each were carried out in the plot in RCB design. The recommended NPK, FYM and biofertilizer (Azotob...

In order to prepare the multi-functional biofertilizer, thermo-tolerant phosphate-solubilizing microbes including bacteria, actinomycetes, and fungi were isolated from different compost plants and biofertilizers. Except Streptomycesthermophilus J57 which lacked pectinase, all isolates possessed amylase, CMCase, chitinase, pectinase, protease, lipase, and nitrogenase activities. All isolates cou...

This research was aimed at assessing the fertilizer quality and public health implications of using digestate biofertilizer from the anaerobic digestion of food wastes and human excreta. Twelve (12) kg of food wastes and 3kg of human excreta were mixed with water in a 1:1 w/v to make 30-l slurry that was fed into the anaerobic digester to ferment for 60days at mesophilic temperature (22-31°C). ...

Sugar-cane bagasse (SCB) is used for pectinases production from Thermomyceslanuginosus at 55°C under solid-state fermentation (SSF).The study aims to purify total PNL and PL enzymes produced from SCB as the sole carbon source at 55°C using microbial fermentation technology, and to evaluate the fermented bagasse residuals as fertilizer for the purpose of combatting soil desertification and then ...
