In order to investigate the appropriate combination of chemical and bio-fertilizers and their effectiveness on corn seed yield while defoliating the upper leaves of the ear, a randomized complete block design experiment with four replications. Fertilizer treatments were applied at four levels including 100% urea, 75% urea + 100% Nitroxin, 50% urea + 100% Nitroxin, 25% urea + 100% Nitroxin. In h...

review and goals: the ajowan(carum copticum) is a medicinal plants from apiaceae family that seeds contains 2-4% of volatile oil. 9-17 of chemical composition of ajowan essential oil have been reported(2), it have antibacterial and antioxidant activity of it caused to preserve the food materials(1). the application of chemical fertilizer leads to environmental pollution and ecological disaster ...

The use of centrifugal spreaders for application of granular fertilizers raises concern about application accuracy. These spreaders enable to distribute almost uniform deposits with regularly spaced parallel tramlines but lead over and under fertilizer application when distances separating the successive tractor trajectories are not constant or if paths are not parallel between them. The aim of...

_Treating the wastewater with high level of urea and ammonia-nitrogen is one of the problems faced by urea fertilizer plants in Indonesia. The alternative treatment being studied is the one which uses Fenton oxidation process which is continued with the use of Pseudomonas fluorescens bacteria. This study is conducted with the concentration of ammonia-nitrogen of 2500 ppm, 2000 ppm, and 1500 ppm...

in order to understand the effects of different organic and chemical fertilizer on stigma yield, corm characterstics and leaf dry matter yield (as a forage) of saffron (crocus sativus l.), an experiment was conducted in the research station of faculty of agriculture, ferdowsi university of mashhad, iran, in 2005-2009; as a randomized complete block design with 12 treatments and three replicatio...
