in order to investigate the effect of consumption of nitrogen and phosphorus fertilizers on harvest indices and some important agronomic traits of triticale (triticosecale wittmack var. javaniloo), a factorial experiment based on the randomized complete block design with three replications was conducted in paddy field of rice research institute of iran (rasht) during 2010-2012 for two years. th...

In order to help farmers to understand soil nutrients, use effectively our soil and protect our environment, at the same time to improve sustainable development of the agricultural system, the topsoil samples were collected form yushu city .The ways of combining Geostatistics with GIS were applied to analyze the spatial variability of soil nutrients, such as Alkaline hydrolysis nitrogen, availa...

We examined whether a difference in potassium dihydrogenphosphate (KH2PO4) and potassium tripolyphosphate (K5P3O10) as dietary phosphorus sources could differentially effect the nephrocalcinosis and proximal tubular function in female rats. Rats were fed on a diet containing KH2PO4 or K5P3O10, at the normal phosphorus level (normal phosphorus diet) or at a high phosphorus level (high-phosphorus...

although the indian population is largely vegetarian, not much attention has been given to the cultivation of vegetables, as compared to other crops like cereals, pulses and oil seeds. therefore, the present study was conducted on two leafy vegetables, spinach (spanacia oleracea l.) and methi (trigonella foenum graecum l.) commonly grown in aligarh, as the two popular vegetables of indian diet....

due to the limited availability of phosphorus in soil especially calcareous soils, it is important to investigate strategies to increase ability of phosphorus uptake by plant. evaluating the effect of zeolite (clinoptilolite), irrigation levels and preferential flows, simultaneously and independently, on increasing phosphorus uptake by corn was objective of this study. potted study was done in ...

Root cortical aerenchyma (RCA) is induced by hypoxia, drought, and several nutrient deficiencies. Previous research showed that RCA formation reduces the respiration and nutrient content of root tissue. We used SimRoot, a functional-structural model, to provide quantitative support for the hypothesis that RCA formation is a useful adaptation to suboptimal availability of phosphorus, nitrogen, a...

Soil salinity and water deficit are major problems for development of agricultural production. In this study, effects of growth promoting microorganisms (inoculation with Piriformospora indica and two isolates of Streptomyces sp.) on the leaf yield and absorption rate of some elements in leaves and roots of stevia plant was investigated under salinity conditions for two consecutive years (2016-...
