intercropping is one of the management methods for crop production and leads to improvement of resource absorption and use by plants. based on this purpose the present field study was conducted to evaluate radiation absorption and uses efficiency in corn and bean strip intercropping at the farm of the faculty of agriculture, ferdowsi university of mashhad, iran during 2009. the experiment was s...
Maize streak virus (MSV), which causes maize streak disease (MSD), is one of the most serious biotic threats to African food security. Here, we use whole MSV genomes sampled over 30 years to estimate the dates of key evolutionary events in the 500 year association of MSV and maize. The substitution rates implied by our analyses agree closely with those estimated previously in controlled MSV evo...
This study was conducted to determine the potential evapotranspiration (PET) of maize, the crop coefficient (Kc) under full water requirement as well as the cause of decrease in maize yield. It was determined that the seasonal PET of maize is about 486.6 mm. The Kc under full water supply was found to be: 0.11, 0.35, 1.51 and 0.34 for initial, development, midseason and the late season stages r...
Background: The main aim of this study was to investigate the nutritional value maize samples grown under different rates blended fertilizer in Wolaita Zone, southern Ethiopia. Methods: Maize that were combined application two fertilizers (K and NPSB) with ratio (0:0, 25:50, 50:100, 75:150 100:200) kg ha-1 used as treatment. content nutrients from determined by flame atomic absorption spectrome...
A total of 280 unsexed broiler chicks, 21 days-old and weighing 580 g on average were randomly distributed into 28 experimental units of 10 birds each. Seven experimental diets containing respectively 0% (T0 control), 20% raw cowpeas (T1), 20% raw cowpeas + 0.2% of Canarium charcoal (T2), 20% raw cowpeas + 0.2% maize cob charcoal (T3), 20% cooked cowpeas (T4), 20% cooked cowpeas + 0.2% Canarium...
Fresh water scarcity has become a global problem which needs a serious attempt to find proper solutions for decreasing the pressure on the limited water resources. The exact estimation of crop virtual water would help with choosing crops with high crop and water productivity which lead to both food and water security. Thus, in this research, maize virtual water was estimated using HYDRUS2D base...
In order to evaluate the effect of sowing date and cultivar on accumulated heat unit, phenology and yield of maize (Zea mays L.), a two-year field study was carried out at the Agricultural Research Station of College of Agriculture, Shiraz University, Shiraz, Iran. Treatments consisted of five maize hybrids (SC704, Hido, BC677, BC666 and NS540) and five planting dates (May 15, June 1, June15, J...
in order to study the intercropping effects of maize (zea mays l.) and bean (phaseolus vulgaris l.) and evaluating effect of intercropping on weed biomass, a field experiment was conducted at the agricultural research station, payamenoor university of nagadeh,west- azarbayjan, iran during growing season of 2009-2010. the experiment was laid out as randomized complete block design with three rep...
Melatonin is effective in modulating plant metabolism under stress conditions whereas nitrogen (N) essential for growth. To explore the effects of melatonin and N applications on early growth, associated physiological biochemical traits, cadmium (Cd) uptake maize Cd stress, a pot experiment was conducted. Two levels, i.e., 0 200 μM, two 1/4 full dose Kimura nutrient solution, were employed wide...
