to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...

a study was conducted to investigate the genetic variance components and the combinig ability of sunflowers lines at the seed and plant improvement institute, karaj, iran in 2006. a total of 41 genotypes including 2 cms, 13 restorer and their 26 corresponding hybrids were evaluated in a line × tester approach. the analysis of variance indicated that significant differences existed among genotyp...

Seasonal variation (e.g. temperature and photoperiod) between growing seasons might affectinulin content and inulin yield of Jerusalem artichoke. However, there is limited information ongenotypic response to seasons for inulin content and inulin yield. The objective of this studywas to investigate the variability in genotypic response to seasons for inulin content and inulinyield of Jerusalem a...

in order to evaluate effects of water stress and foliar application humic acid on quantities and qualitative in borage, a field experiment was conducted as a split plots design with three replication in 2012 at agricultural research station, university of zabol. water stress treatments included control or 90 percent of field capacity (w1), 70 percent field capacity (w2) and 50 percent field cap...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...
