In order to evaluate the effect of concentration and time of foliar spraying of nitrogen fertilizer as complementary of soil nutrition on dry matter remobilization and seed and oil yield of rapeseed (Hyola401), an experiment was conducted in complete randomized block design with 16 treatments and three replications in two years (2008-2010) in Rice Research Institute of Iran (Rasht). In this exp...

Effect of different times and levels of nitrogen fertilizer application on growth and grain yield of spring wheat cultivar “Ghods” was studied during 1993-1994 growing season at Karkadj, Agricultural Experiment Station, College of Agriculture, University of Tabriz, using a split plot design with three replications. Main plots were assigned to five levels of N fertilizers (0, 40, 80, 120 and 160...

Current research was performed to identify molecular markers associated to phonological traits including days to tillering, days to stem elongation, days to heading, days from stem elongation to heading, grain filling period and days to physiological maturity based on 407 AFLP and SSR markers in 148 barley cultivars by association mapping. This experiment was conducted in two alpha lattice desi...

To estimate required parameters of phenology sub-model in SSM-Wheat model (cardinal temperatures, critical photoperiods and photoperiod sensitivity coefficient) and to determine of the biological day for eight bread wheat genotypes (Morvarid, Tajan, Kohdasht, Darya, Gonbad, Arta, N-87-20 and N-87-19) in Golestan province of Iran in 12 sowing dates, an experiment was carried out using randomized...

A factorial experiment (based on completely randomized design) with three replications was conducted in faculty of agriculture of Urmia University, Iran in 2016 to investigate the effect of soil Zn deficiency on the expression of genes encoding bZIP4, bZIP79 and bZIP97 transcription factors in Zn-efficient and Zn-inefficient bread wheat cultivars. Cv. Bayat (Zn-efficient) and cv. Hirmand (Zn-in...

To determine the proper nitrogen fertilizer rates and its application times for achieving high grain and oil yields of rapeseed cultivar, Hyola 401, a research was carried out in paddy fields of Rice Research Institute of Iran in Rasht during two cropping seasons. A factorial experiment was conducted in a completely randomized block design with three replications. The experimental factors w...

The optimum levels of soil moisture and nitrogen are important to obtain higher yields. To investigate the effects of water stress, nitrogen levels and application times on yield and yield components of sunflower (Helianthus annuus L.), the cultivar Euroflor at different growth stages, a two year study (2006-007) was conducted at Research Fields of College of Agriculture, Shiraz University (Bad...
