“…Increase in number of DA could be due to increased vegetative growth. Similar approaches were reported by De Varennes et al, [8] and Sadras [9], that cultivars differed significantly in phenology and this difference might be due to varietal behavior of sunflower. The interactive effects were nonsignificant among all the treatment.…”

The experiment was conducted to study the effect of varying plant population and nitrogen rates on growth, development, yield and quality of sunflower hybrids at research area of University College of Agriculture, Sargodha, during spring season, 2011.The treatments include two hybrids (Hysun-33 and S-278) and three planting densities (8.33, 6.66 and 5.55 plants m-2) with three rates of nitrogen (100, 125 and 150 kg ha-1). The obtained results revealed that there was a significant difference for days taken to anthesis (R 5.8 stage) and physiological maturity (R 9 stage), and achene yield (AY) as well as achene oil contents (AOC) in both of the hybrids except Leaf area index (LAI) and total dry matter (TDM). The hybrid S-278 started reproductive stages and matured earlier and gave higher achene's yield (3.34 t ha-1) than hybrid Hysun-33 (2.73 t ha-1). Increasing plant density increased the days taken to anthesis (DA) and physiological maturity (DPM), LAI, TDM, AY, AOC in sunflower. Similarly, with increasing nitrogen application phonological duration, LAI, TDM and AY was increased but AOC were reduced. The interaction between hybrids and planting densities (HxD), hybrids and nitrogen (HxN), Planting density and nitrogen (DxN) were non-significant for all the parameters.

“…However, Diaz Ortega et al ( 2004) found no differences associated with the experimental treatments. On the other hand, several authors demonstrated an increase in the number of days among different growth stages, resulting in a prolongation of the vegetative period when a fertilizer was applied (Kho 2000;Prasad et al 2002;De Varennes, Melo-Abreu, and Ferreira 2002;Moujiri and Arzani 2003;Sadras 2006;Bakht et al 2010;Hafiz et al 2013).…”

This article explores the response of three genotypes of Amaranthus to different sowing date and to different doses of nitrogen (N) fertilization. The experimental design was a randomized complete block design with three replicates for cultivars, planting date and fertilization per treatment. Mexicano sown in early December had the best yield (5285 kg ha -1 ) with highly significant differences (p < 0.001) respect to Dorado and Antorcha. To assess the N fertilization Mexicano cultivar was sown at the end of spring (1 December). Morphophysiological variables increased as the N fertilization dose was raised. Higher doses of N fertilizer resulted in greater economic yields this was mainly due to the increase in grain number rather than that of a 1000 grain weight. The results of this investigation suggest that sowing Amaranthus cruentus cv Mexicano on 1 December with 150 kg N ha À1 favors its general development and allows to obtain high economic and biological yields with an appropriate protein content.
