to evaluate the effect of drought stress, biofertilizer and chemical phosphorus fertilizer on yield and seed protein percentage of two lentil cultivars, an experiment was conducted in split factorial based on crbd design with 4 replications in research farm of university of tehran (karaj-iran) during 2009-10. the main factor including three irrigation levels (irrigation after 70, 90 and 130 mm ...

Of the factors tested, the source and concentration of carbon and nitrogen in the medium exerted maximum effect on growth and acid production. Glucose (15%) and urea (0.14%) induced glucose oxidase synthesis and optimum yield of calcium gluconate. Potassium dihydrogen phosphate (0.2%) and magnesium sulphate (0.06%) stimulated glucose oxidase activity and calcium gluconate production. Borax at a...

in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...

1. The preparation, purification, chemical and spectral properties of potassium 4-methylumbelliferone sulphate are described. 2. The use of 4-methylumbelliferone sulphate as a substrate for the arylsulphatase of Patella vulgata is presented with specific reference to the fluorimetric assay procedure used with this substrate. 3. 4-Methylumbelliferone sulphate is compared with the previously used...

Four phosphorus forms were investigated as potential soil amendments to decrease the bioavailability of Pb and Zn in two repository soils to the earthworm, Eisenia fetida. Treatments were evaluated by examining differences in bioaccumulation factors between amended and non-amended soils. Triple super phosphate at 5000 mg P/kg decreased both Pb and Zn bioavailability in both soils. Rock phosphat...

Groundwater is prime and major source of drinking water in our world. Jharkhand also used for drinking, domestic, irrigation, mining industrial etc. purposes. In some population are suffering from scarcity pure have partial facility with as groundwater many area contaminated fluoride, arsenic, heavy metals iron dangerous chemicals. This review paper focuses on current status contamination diffe...

Aim: The aim of the present study was to examine different forms sulphur fractions in post- harvest soil cabbage crop determine S status red sandy loam soil, Thondamuthur block, Coimbatore district.
 Study Design: design used Factorial randomized block with 20 treatments replicated thrice.
 Place and Duration Study: A field experiment carried out a farmer’s non-calcareous deficient wh...

A field experiment was carried out in the Research and Production Station, National Research Center, El-Nobaria during the season, 2009 to evaluate the effect of cobalt and different sources of phosphorus fertilizers on the growth, yield quantity and quality of tomato. Treatments can be arranged in descending order as follows: Mono super phosphate (MSP) > Triple super phosphate (TSP) > Rock pho...
