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...

A study was undertaken to determine the effects of different biofertilizers on growth and seed barley, Bahman cultivar in Iran. The trial was laid out in RCBD with split plot arrangement having three replications during 2011-12 and at Boroujerd, Iran. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate  biofrtilizers (Phosphate barvar2, Bi...

Increasing the area of arable oilseed land, particularly rapeseed, and the important role of potassium in yield and oil content, especially in calcareous and high pH soils, need to more knowledge about plant nutrition requirement. In this study, the effect of sources and different levels of potassium fertilizers on some quality and quantity characteristics on canola yield were assessed by combi...

Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield in sunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., days to 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield per plant. The lines 27, 43...

A field experiment was conducted for two consecutive seasons (2009/10 and 2010/11) in the Demonstration Farm of the Faculty of Agriculture at Shambat-Sudan, to study the interactive effect of nitrogen fertilization and rhizobium inoculation on nodulation and yield of soybean (Glycine max [L.] Merrill) plants. The experiment was laid out in a randomized complete block design with four replicatio...

Chickpea (Cicer arietinum L.) is one of the most important crops worldwide that is a subject of many plant breeding programs in many countries. In addition, climates are changing all over the world and drought becomes one of the most serious problems versus yield of crops. In order to screen drought tolerant genotype in Chickpea, twenty genotypes were tested under rainfed and irrigated...
