biofertilizers are natural inputs that can be applied as complement or substituent of chemical fertilizers in sustainable agriculture. effects of n and p bio- and chemical fertilizers on growth indices of maize (zea mays l.) was studied on 2008 in shushtar, iran, based an as a factorial experiment based on completely randomized block design with three replications. treatments consisted four lev...

Adding organic matter to soil proved an efficient strategy for restoring fertility and improving crop dry – indicator of yield potential. In this regard, evaluating the sources (OM) (control, poultry manure [PM], farmyard [FYM], compost, mungbean residues [MR]) provide 120 kg N ha-1 effective microbes (EM) (0, 100, 200, 300 L ton-1 OM) as 2% solution proceeded in field conditions during 2017–20...

A split-split-plot design with three replications in two years of 2009 and 2010 was conducted to investigate the effect of different levels of irrigation water (main plot), salinity of irrigation water (sub-plot) and nitrogen fertilizer rate (sub-subplot) on maize growth rate and gas exchange. Irrigation treatments were I1 (1.0 crop evapotranspiration (ETc)+0.25ETc as leaching), I2 (0.75I1)...

High doses of nitrogen (N) fertiliser input on permanent pastures are crucial in terms N surplus and losses. Quantitative analyses the response plant functional traits (PFT) driving crop growth rate (CGR) under low lacking frequently defoliated pastures. This study aimed to understand significance PFTs for productivity uptake grasslands by measuring dynamics tiller density (TD), weight (TW), le...

21 century. Such an increase in the atmospheric CO may effect plant growth and productivity of crop plants. st 2 A field experiment was conducted with two potato cultivars namely Kufri Surya and Kufri Chipsona-3 grown inside Open Top Chambers (OTCs) at ambient (385±30 μmol mol ) and elevated CO (570±50 μmol mol ), 1 1 2 during rabi season of the year 2009-2010. The experiment was planned in a r...

Genotype, environment and agronomic practices are key determinants of crop growth productivity which important to provide food, feed, raw materials income small holder farmers in Africa. The study was conducted at Crop museum, Sokoine University Agriculture, Morogoro, Tanzania investigate physiological response groundnut calcium phosphorus nutrition among three improved genotypes Mangaka (G1), ...

Coffee is one of the most socioeconomically important crops worldwide. Currently, environmental variations due to climate change are affecting coffee development and growth. Therefore, it evaluate areas that offer a different environment during seedling stage since fundamental for successful cultivation. Four municipalities located at altitudes in Department Nariño were selected: La Florida (18...

in order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in isfahan. the experiment was conducted as split plots in a randomized complete blocks design with three replications in isfahan (51° 48' e, 32° 40' n).main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class a and cultiv...

in order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the college of agriculture, shiraz university, shiraz, iran during 2010 and 2011 growing seasons. two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...
