BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Improve saving water in irrigated agriculture and thereby improving water use efficiency is of paramount importance in water-scarce regions. OBJECTIVES: This study was conducted to assessment effect of different levels of irrigation re...

The tomato leafminer, Tuta absoluta (Meyrick) is a devastating pest associated with tomato. In this study, effects of tomato plants treated with vermicompost (20, 40, and 60%), humic fertilizer (2, 4 and 6 g/kg soil) and plant growth promoting rhizobacteria (Pseudomonas fluorescens and Bacillus subtilis) were investigated on the life table parameters of T. absoluta in a growth chamber at 25 ± 2...

This research illustrates the qualitative and quantitative composition of the mycoflora of both a green compost (thermophilically produced from plant debris) and a vermicompost (mesophilically produced by the action of earthworms on plant and animal wastes after thermophilic preconditioning). Fungi were isolated using three media (PDA, CMC, PDA plus cycloheximide), incubated at three temperatur...

The effects of applications of food waste and paper waste vermicomposts on some soil chemical and biological properties were evaluated in field plots planted with strawberries. Six-week old strawberries (Fragaria ananasa, var. Chandler) were transplanted into 4.5 m(2) raised beds under a plastic tunnel structure measuring 9.14 x 14.6 x 3.6 m. Vermicompost were applied at rates of 5 or 10 t ha(-...

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...

As per the estimates of World Health Organization (WHO) about 80% of world’s population depends on plant and plant products for their primary healthcare. Recently the demand for herbal drugs has increased many folds at the global level, as these herbal medicines do not have any side effects and its cost effectiveness. Huge quantities of solid waste is generated during the production of decoctio...

in order to study the effects of vermicompost and biological fertilizers on vegetative yield and essential oil of basil (ocimum basilicum l.), an experiment was conducted based on a complete randomized block design with nine treatments and three replications at mashhad during growing season of 2009-2010. the treatments were: 1) vermicompost, 2) nitroxin (included: azotobacter sp. and azospirill...

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...

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 ...
