In order to study the effects of intercropping maize with legume on forage quantity, field experiments were carried out at the Agricultural Research Station, Faculty of Agriculture, University of Tabriz, Iran, in 2006 and 2007 growing seasons. Two maize (Zea mays L.) hybrids (SC704, SC301), vetch (Vicia villosa), bitter vetch (Vicia ervilia), berseem clover (Trifolium alexandrinum L.) and commo...
drought stress is the most important environmental constraint contributing to grain yield instability of maize(zea mays l.). evaluation of maize genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield potential for stress-prone areas. this study was conducted to estimate grain yield stability of maize hybrids and to identify hybrids th...
in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...
Drought stress is the most important limiting factor in crop plants including maize (Zea mays L.), which is the third important world crop after wheat and rice. Water deficiency at different growth stages affects maize yield differently. To examine the response of four maize hybrids to drought stress at different growth stages, a field experiment was carried out as a split plot based on complet...
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...
a total of twenty local and foreign maize (zea mays l.) hybrids in five different maturity group were studied in mashhad for two years (2007-2008). temperature variations were created by two planting dates (5 may and 20 may). results indicated that both indices, gdd and chu, estimated heat units of different maturity hybrids and based on, created similar groups of hybrids. both indices showed s...
The closest wild relatives of maize, Zea mays ssp. mays are various Zea taxa known as "teosinte." Hybrids between maize and the teosinte taxon, Zea mays ssp. mexicana, often occur when the 2 are sympatric in Mexico. Measuring the spontaneous hybridization rate of the 2 taxa would shed light on the mechanisms contributing to the evolution and persistence of these hybrid swarms. We conducted a se...
The aim of present study was to evaluate the effects of drought stress on net photosynthesis rate (Pn), stomatal resistance, water use efficiency (WUE) and biomass (BM) of six maize (Zea mays L.) hybrids. Drought stress applied by withholding water supply at 4-5 leaf stage (S1, vegetative stage), anthesis (S2, reproductive stage), and dual stress condition (S3, combination of vegetative and rep...
In order to study the effect of different intercropping combinations on some maize qualitative traits, an experiment was conducted as a completely randomized block design with three replications in Agricultural Research Station, Faculty of Agriculture, University of Tabriz, Iran, in 2006 and 2007. Two maize (Zea mays L.) hybrids (704, 301), vetch (Vicia villosa), bitter vetch (Vicia ervilia), b...
a study was conducted to evaluate the effects of plant growth promoting rhizobacteria (pgpr) inoculants including four strains of azotobacter chroococcum, azospirillum lipoferum, a. brasilense and pseudomonas fluorescence on dry matter accumulation of late maturing maize(zea mays l.) hybrids, sc704, sc700 and a promising single cross b73×k18. a factorial experiment was conducted in research fie...
