in order to study the effect of uniconazole and cycocle growth regulators on growth, yield and nutrients content of pearl millet in drought stress condition, a field experiment was conducted in 2007-2008 in agriculture research center of zabol university. the experiment was conducted in split plot base on randomized completely block design with tree replications. main plots were different level...

In order to study the effect of vermicompost and nitrogen fixing bacteria on seed yield, yield components of seed and essential oil content of coriander (Coriandrum sativum), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of Agriculture Company of Ran in Firouzkuh of Iran in 2012...

in order to evaluate the effect of organic fertilizers (compost) and nitrogen on growth and yield of moldavian balm, a split plot experiment in a randomized complete block design with four replications in 1393 at the research station of kerman agricultural and natural resources research and education center was performed. the main plots and subplots of the experiment, respectively, were include...

Yield and lodging related traits are essential for improving rapeseed production. The objective of the present study was to investigate the influence of plant density (D) and nitrogen (N) rates on morphological and physiological traits related to yield and lodging in rapeseed. We evaluated Huayouza 9 for two consecutive growing seasons (2014-2016) under three plant densities (LD, 10 plants m-2;...

We aimed to establish standards for tobacco Valor de Cultivo e Uso (VCU) in Brazil. We obtained information regarding the size and design of plots of two varietal groups of tobacco (Virginia and Burley). Ten inbred lines of each varietal group were evaluated in a randomized complete block design with four replications. The plot contained 42 plants with six rows of seven columns each. For each e...

A survey of 153 acid grasslands from the Atlantic biogeographic region of Europe indicates that chronic nitrogen deposition is changing plant species composition and soil and plant-tissue chemistry. Across the deposition gradient (2-44 kg N ha(-1) yr(-1)) grass richness as a proportion of total species richness increased whereas forb richness decreased. Soil C:N ratio increased, but soil extrac...

BACKGROUND: Azospirillum is effective in biostabilization of nitrogen and Pseudomonas is effective in dissolving soil phosphorus. OBJECTIVES: Current study was conducted to assess effect of different level of nitrogen and biofertilizer on seed yield, its components and protein content. METHODS: This research was carried out via spilt plot fac...

BACKGROUND: Wheat produces more than 50 percent of requirements protein and calorie for human nutrition in Iran. Management of nitrogen fertilizing is important to increasing wheat production. So, among chemical fertilizer a high correlation reported between nitrogen and yield. Also to improve physical, chemical and biological properties of soil, organic fertilizer such as verm...
