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...

to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...

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...

chemical fertilizers are threat in hman life and today application of biological fertilizer find more important. this study performed in order to evaluate the effects application of biofertilizers with urea fertilizer on yield, protein percentage and numbers of eyes in plant, plant height and chlorophyll spad in potato var. marphona. a factorial experiment was conducted based on randomized comp...

background & aim: nowadays, tendency to agricultural biotic product sustainable agriculture instead of chemical ‎fertilizers has been going up in all over the world. so, most pharmaceutical industries prefer to ‎use raw material which is produced from organic and stable system. producing organic ‎medicinal plants, such as peppermint, seems important in economical, ecological and ‎bio enviro...

BACKGROUND: Nitrogen is a crucial component of plant nutrition, and its deficiency limits productivity of crops more than any other element. To manage the sorghum crop for achievement of maximum forage production, the farmer should be concerned about nitrogen requirement and plant height. OBJECTIVES: This research was carried out to evaluate response of m...
