The effect of four different levels of irrigation periods, including normal irrigation, irrigation after 100, 150, and 200mm evaporation, with three different bio-fertilizer including control, Mycorrhiza, and Rhizobium were investigated on morphological and yield traits of guar. The experiment was conduct in form of split-plot design with irrigation periods as main plots and bio-fertilizers as ...

plant population density (ppd) and nitrogen (n) have large effects on chickpea growth and yield. to study these effects on chickpea (var. kourosh) a factorial experiment (4×3) in randomized complete block design with four replications was carried out at research farm of college of agriculture & natural science, karaj (iran) in 2006. four ppd treatments were 16, 32, 48 and 64 plant m-2 and n amo...

this study set out to investigate the effect of bio-fertilizers containing nitrogen-fixing bacteria and phosphorus on grain yield and yield components of faba bean. to this end a factorial experiment on the basis of randomized complete block design with four replications was conducted in behbahan region at south eastern part of khuzestan province of iran. the experimental treatments included ni...

this study carried out in a factorial layout on completely randomaized block design with three replications, to evaluate the above- and below- ground competition between sesame (sesamum indicum) and pigweed (amaranthus retroflexus), and their impacts on sesame yield and yield component. the experimental treatments were all combination of crop-weed competition (shoot competition, root competitio...

Biological fertilizers are compounds comprising various free living microorganisms that are able to change the basic nutrients into available form through biological procedures. Being an important source of nutrients in sustainable agriculture, these fertilizers lead to better seed germination and development of root system. In order to investigate the effect of biological fertilizers on the me...

this experiment was carried out to investigate the effect of plant density on growth and seed yield of wheat (kodasht cultivar) under saline soils and rainfed condition inanbarolum region of golestan province in 2008-09. an experiment was conducted in three fields with different salinities (6.73, 9.34 and 11.63 ds m-1) based on randomized complete blocks design. treatments were four plant densi...

recently, biofertilizer application is growing to meet sustainable agriculture goals. the present experiment was designed to evaluate four nitrogen levels (0, 60, 90 and 120 kg n.ha-1) as main plots, two supernitroplus biofertilizer levels) with and without biofertilizer) as sub-plots on yield and yield components of three sesame cultivars (naz, oltan and varamin (as sub-sub-plots in a split-sp...
