variable rate application (vra) based on site specific crop management (sscm) is an effective approach for optimizing the application of agricultural inputs and preventing the undesirable environmental impacts. design, construction and evaluation of a map-based vra system was the main objective followed in this research. for variable rate application based on the generated map, a direct injecti...

to evaluate the effect of humic acid and phosphorus on the quantity and quality of marigold yield an experiment was conducted at research field of islamic azad university, mashhad branch, mashhad, iran, in cropping season 2010-2011. the experiment was in split plot based on randomized complete block design, with four replications. the main plots were humic acid in four levels (0, 5, 10 and 15 k...

faba bean is one of the proper crops for cultivation in guilan climate conditions in rotation with rice. one of the limiting factors in development of cultivating this plant is late maturity and synchronizing of its ripening with rice transplanting. to investigate the effect of planting date, timing and consumption rate of paraquat herbicide on the ripening, grain yield and some of the agronomi...

Herbicide plays the main role in guaranteeing the quantity and quality of food. Soybean reactive oxygen species scavenging system eliminates the herbicides’ side effects on the plant by activating antioxidant enzymes, which affects the yield. So, we investigated this procedure to reveal the effect of herbicides on food production. Methods: Experiments were carried out in two locations of Alborz...

abstract to investigate the effects of paclobutrazol (pbz) on vegetative and reproductive growth of strawberry cv. selva a factorial experiment in a completely randomized design with three replications was carried out in greenhouse of agriculture college, isfahan university of technology. pbz was applied in two methods, drench and foliar spray, at 0, 0.5, 1, 1.5 and 2 mg active ingredient per p...

In this paper, authors summarise studies refferering to enrichment of breast and thigh muscles with carnosine that has an important function in physiological processes. Research shown improves quality chicken meat. By adding amino acids β-alanine L-histidine chickens’ feed, synthesizes skeletal muscles, brain, heart muscle olfactory receptor cells. It been determined the content depends on type...

on the bacterial viability of S. mutans, A. israelii, P. gingivalis, A. actinomycetemcomitans, E. corrodens, C. rectus, K. oxytoca, K. pneumoniae and E. cloacae. The percentage of live bacteria was tested by fluorescence method using Live/Dead kit® and BacLight (Molecular Probes®) and compared between groups by the Kruskal-Wallis and U Mann-Whitney tests with Bonferroni correction (p value<0.01...

Incomplete degradation of control products and subsequent carryover of active ingredient to the next year are operational concerns for control agencies. Altosid XR briquets were weighed before and after 6-18 months of exposure in temporary wetlands to determine the rate of physical degradation of the briquets. Degradation rate was influenced mainly by the number of days a briquet remained under...
