Three quarters of the world’s phosphate deposits are of sedimentary origin and 75%–80% of those include carbonate gangue. In this study, carbonate sedimentary phosphate deposits of the Lar Mountains of southwest Iran are studied. These deposits consist mainly of calcite, fluorapatite, quartz, kaolinite and illite, with an average P2O5 grade of 9%–10% (low-grade). Various pre-processing and proc...

The response of human myeloid leukemia cells to various sources of colony-stimulating activity (CSA) and media conditioned by phytohemagglutinin-stimulated mononuclear cells (PHA-LCM) was investigated in liquid and colony culture. PHA-LCM, placenta-conditioned medium, GCT cell line-conditioned medium, leukocyte-conditioned medium, and partially purified CSA for human and murine cells were teste...

The relationship between the dietary level of vitamin E (VE) and the immune response of broilers was studied in three experiments. Immunity was assessed as antibody production to infectious bronchitis virus (IBV), SRBC, and Brucella abortus (BA) antigens, mitogenic response to phytohemagglutinin A (PHA) and concanavalin A (Con A), cutaneous basophil hypersensitivity (CBH) to PHA, and lipopolysa...

At the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, a field experiment was undertaken during Rabi season 2022. The soil texture experimental plot sandy loam, with pH 7.1, low organic carbon (0.28 percent), available N (225 kg/ha), P (19.50 and K (213.7 kg/ha). Rhizobium sp (20g/kg seed), PSB + (10g/kg seed 10g/kg seed) were used as bio-fertilizers, phosphorus (50 kg P2O5/ha, 6...

Phosphorus (P) and Sulphur (S) are the most important plant nutrients which play significant roles in enhancing early growth development increasing fodder yield of maize. This field study was planned to evaluate P-S interaction effects on maize growth, nutrient (P S) uptake. The soil used for clay loam, medium-alkaline (pH: 7.9), non-saline (EC: 0.85 dS m-1), strongly calcareous (CaCO3: 24 %), ...

A field experiment was conducted to determine the response of different doses of N and P2O5 on the growth and flower quality of gladiolus at farmer field district Quetta during the summer season 2008. Six treatments were included in the trial viz; T1 (125+100); T2 (125+200); T3 (150+100); T4 (150+200); T5 (175+100) and T6 (175+200) NP kg/ha were tested in four replicated randomized complete blo...
