In order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, Ardabil, Iran, in 2007. Experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

one of the strategies for improving the quality of agricultural products is using bio-fertilizers. so in order to study the effects of mycorrhizal fungi, vermicompost and humic acid on growth characteristics and yield of fennel, an experiment was studied on research farm of agricultural college of shahrood university. this study was conducted as factorial experiment based on completely randomiz...

aftab cultivar originated from national cereal breeding programs .the new cultivar  was evaluated in international high rainfall wheat yield trial nursery at gachsaran and gonbad agricultural research stations (2008-2009). due to optimum grain yield and other agronomic traits, the new cultivar was tested in advanced yield trials in gachsaran, ilam, khoram abad and gonbad research stations (2009...

Crown rust, caused by the fungal pathogen, Puccinia coronata Corda var. avenae W.P. Fraser Ledingham, reduces kernel quality and grain yield in oat (Avena sativa L.). Partial resistance is considered to be a durable form of rust resistance. This study sought to evaluate the feasibility of simultaneously improving partial resistance to crown rust, grain yield, and seed weight in an oat populatio...

Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining yield and improving flour quality. A field experiment was conducted to examine the responses of three spring wheat varieties in pure variety and in variety mixtures under continuous cropping in Northeast China. Three modern spring wheat varieties, along with a three-variety mixture and a t...

line s-80-18 (deberia) a spring bread wheat line with pedigree of hd160/5/tob/cno/23854/3/nai60//tit/son64/4/lr/son64 was selected from the high temperature wheat yield trial, received from cimmyt and evaluated at zabol research station in 1994-95 cropping season. as a superior line, it was advanced to the preliminary yield trial at zabol station in 1995-96 cropping season. due to high grain yi...

an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...

A pot experiment was conducted in rabi season 2004-05 to study the effect of Kappaphycus alvarezii extract applied as a foliar spray at 0.25%, 0.50% and 1.0% on wheat. Compared to control the yield of grain increased by 80.44% when, the plants were sprayed with 1.0% K. alvarezii extract. The nutritional quality of grain such as carbohydrate, protein and minerals also improved under the influenc...
