to investigate the effect of deficit irrigation and macro and micro fertilizers on morpho-physiological characteristics of satureja a field experiment was conducted in agricultural research station of haji-abad (hormozghan province-iran) a split plot randomized complete block design with three replications during the growing season of 2012-2014. irrigation treatments consisted of normal, modera...

The present investigation was carried out under open field conditions during the year 2018-19 to ascertain influence of spent mushroom compost, biofertilizers and foliar application water soluble fertilizer, Mono Potassium Phosphate (MKP) on flower yield economics French marigold ‘Local’. results revealed that overall cost cultivation as well production significantly influenced by various Integ...

this experiment was conducted as randomized complete block design with three replications in 2012 at university of zabol. experimental treatments included phosphorus fertilizer at three levels of 0, 100 and 200 kg.ha-1 as the first factor and foliar humic acid at four levels of 0, 750, 1500, 2250 g.1000 l water as the second factor. results showed phosphorus treatment had significant effect on ...

Cowpea (Vigna unguiculata) is a major source of dietary protein and essential component of the cropping systems in semi-arid regions of Sub-Saharan Africa. However, yields are very low due to lack of improved cultivars, poor management practices, and limited inputs use. The objectives of this study were to assess the effects of rhizobia inoculant and P on nodulation, N accumulation and yield of...

in order to evaluate nitrogen fixation ability and nutrients uptake in three cultivars of common bean (phaseolus vulgaris l.) inoculating with some types of inoculants containing different strains of rhizobium leguminosarum; bv. phaseoli an experimental design was conducted in khoramdarah region in 2006 and 2007. in this investigation three types of biological fertilizers including rb117, rb123...

The effect of fertilizer rate on fruit quality parameters in the black chokeberry (Aronia melanocarpa [Michx] Ell.) cv. `Viking' was studied over three years. A combined N±P±K fertilizer was applied in different rates. Plant height, yield, berry weight, anthocyanin content, content of brown compounds, content of soluble solids, anthocyanin composition and total acidity were recorded for the dif...

The composition and structure of humic acid (HA) can be affected by fertilization, but the short-term effects are difficult to detect using traditional analysis methods. Using a 35-year long-term experiment in Black Soil, the molecular structure of HA was analyzed with Fourier transform infrared spectroscopy (FTIR), 13C nuclear magnetic resonance spectroscopy (NMR), and fluorescence spectroscop...
