Influence of Plant Population and Nitrogen-Fertilizer at Various Levels on Growth and Growth Efficiency of Maize
Field experiments were conducted to evaluate plant population and N-fertilizer effects on yield and yield components of maize (Zea mays L.). Three levels of plant populations (53000, 66000, and 800,000 plants ha⁻¹ corresponding to spacings of 75 × 25, 60 × 25, and 50 × 25 cm) and 4 doses of N (100, 140, 180, and 220 kg ha⁻¹) were the treatment variables. Results revealed that plant growth, ligh...
متن کاملMicrobial Communities of Spinach at Various Stages of Plant Growth from Seed to Maturity
Little is known about how the leaf bacterial community is affected by the seed microbiota at different stages of plant development. The bacterial populations of spinach seed and leaves after germination were compared using DGGE, to assess bacterial community richness, and realtime PCR to compare the abundance of select phyla (total bacteria, Actinobacteria, Bacteroidetes, Firmicutes, -Proteoba...
متن کاملweed nitrogen uptake as influenced by nitrogen rates at early corn (zea mays l.) growth stages
the effect of nitrogen (n) levels on n uptake by high weed densities at early growth stages of corn (zea mays l., cv. double cross 370) was investigated for two years (2008-2009) at the agricultural research station of shiraz university. the experiment was arranged in a split-plot arrangement in the randomized complete blocks design with three replications. two levels of weed control (weedy and...
متن کاملgrowth and yield response to different nitrogen levels potato plant
this experiment was conducted in andimeshk region (north of khouzestan) to study the effects of nitrogen levels on plant characters of two potato cultivars (solanum tuberosum l.) in identical conditions of poultry manure, in 2012-2013 crop year, as a factorial randmaized complete block design with three replications. the first factor was consisting of four nitrogen levels (0, 70,140 and 210 kg...
متن کاملRapeseed-legume intercrops: plant growth and nitrogen balance in early stages of growth and development
In this study we tested whether legumes can improve the growth and N and S nutrition of rapeseed in an intercropping system and compared the effect of mixtures on legume N-fixation and soil N-resources. Rapeseed was cultivated in low N conditions in monocrops using one (R) or two plants (RR) per pot and in mixtures with lupine, clover or vetch. The R monocrop was the most relevant control, intr...
