paper only the treatments receiving commercial urea prills Using maize as the indicator crop for recently tilled soils over seven successive seasons, urea prills coated with 0,5% polymer gave the greatest grain yield increases over commercial urea in seasons of below average rainfall (3,3 tonsha versus 1,6 tonsha in 1989-90). The ratios of grain to stover were also higher. In wet years, no diff...

To identify environmental risks of vermicompost-borne pollutants after consecutive application for different times, pot experiments were conducted to evaluate the effects of application of polluted vermicompost produced by Eisenia fetida on growth and Cu and Zn uptake of Mexico corn (Euchlaena mexicana) and Sudan grass (Sorghum hybrid Sudangrass) as well as soil characteristics. The results sho...

objective: to evaluate the effects of bacteria and vermicompost on phenology and growth of soybean trial an experiment was conducted as split plot in a completely randomized block design with three replications. methods: main plots of experiment at two levels included the non-use and the use of bacteria and the subplots at three levels included the non-use of vermicompost (control), the use of ...

The effects of vermicomposts on plant parasitic, fungivorous and baterivorous nematode populations were investigated in grape (Vitis vinifera) and strawberry (Fragaria ananasa) field crops. Commercially-produced vermicomposts derived from recycled paper, and supermarket food waste were applied to replicated plots at the rates of 2.5 t ha–1 or 5.0 t ha–1 for the grape crop and 5.0 t ha–1 or10 t ...

Micropropagation is an important technique for rapid and large-scale multiplication of selected plants. The type and concentration of plant growth regulators and physiological status of the explant have profound effect on the efficacy of plant regeneration. However, success of any micropropagation protocol depends upon the percentage survival and successful establishment of plants from in vitro...

application of organic fertilizers increases quality and yields in the sustainable crop production and considerably replaces or reduces chemical fertilizers. in order to study the effects of different manure and vermicompost rates on yield and essential oil contents of dragonhead, an experiment was conducted as a randomized complete blocks design with eight treatments and three replications in ...

Sulfur, organic matter, and inoculation with sulfur-oxidizing bacteria are considered as amendments to increase the availability of phosphorus from rock phosphate. The present study was conducted to evaluate the best combination of sulfur, vermicompost, and Thiobacillus thiooxidans inoculation with rock phosphate from Yazd province for direct application to agricultural lands in Iran. For such ...

The paddy straw is one of the most abundant agricultural by-products in Tamil Nadu, India. It contains approximately 37% cellulose, 24% hemicelluloses and 15% lignin. In the present investigation the paddy straw was pre-digested with Trichoderma viride and subsequently the same was utilized for the production of vermicompost by using Eudrilus eugeniae, Perionyx excavatus and Lampito mauritii un...

The aim of the present study was to assess the genotoxicity reduction in post vermicompost feed mixtures of bagasse (B) waste using earthworm Eisenia fetida. The genotoxicity of bagasse waste was determined by using Allium cepa root chromosomal aberration assay. Bagasse was amended with cattle dung in different proportions [0:100 (B0) 25:75 (B25), 50:50 (B50), 75:25 (B75) and 100:0 (B100)] on d...
