In order to evaluate genetic diversity of grain yield, nitrogen uptake efficiency and selecting superior varieties, a factorial experiment with the based on Complete Blocks design with four replications was carried out in Saatlo agricultural research station, six corn genotypes (single cross 301,370,540,700,701 and Back cross) and three amounts of nitrogen fertilizer (urea) (27 as a control, 11...

The results of nine experiments to study factors influencing the efficacy of N(phosphonomethyl) glycine (as Roundup) in killing sugarcane are reported. These factors include varying rates, methods of application, disturbance of the cane after application, the presence of dew on the foliage during application and the susceptibility of sugarcane varieties. Other factors such as season, soil type ...

Conservation agriculture (CA) is one option for dealing with such a challenge, but its main difficulty in West Africa maintaining permanent soil cover, particularly crop residues, due to their preferential use livestock fodder. The aim of our study was determine the effect residue mulching on efficiency cropping systems based principles conservation agriculture. experimental design on-station e...

Objective:Investigating the microbes and interactions of the beneficial symbiotic relationships between the components of the system ecology in the food chains and life cycles is one of the modern sustainable agriculture topics. In this regard, to evaluate the effects of bacteria and vermicompost on morphological characteristics and yield of soybean an experiment was conducted as split plot in...

in order to investigate the effect of vermicompost (vc) application on amount of micro elements in soil and plant organs of the medicinal plant of borage (borago officinalis), an experiment was carried out in split plot based on complete randomized block design with three replications in the research farm of the sari university of agricultural science and natural resources. fertilizer treatment...

The catalytic properties of modified synthetic (A, X, Y) and natural (MOR, Clp) zeolites have been studied in the reactions oxidative dehydrogenation butyl alcohols to corresponding carbonyl com-pounds. It has established that bimetallic zeolite catalysts show higher activity these

Conservative and sustainable soil management in vineyards is an approach of primary importance not only for the yield (tons per hectare) grapes’ quality (primary secondary metabolites), but also greater preservation ecosystem. Compared to sustained-conventional tillage perpetual applications fertilizers phytopharmaceutical, these techniques give a role safeguarding biodiversity, conserving fert...
