Salinity is an important abiotic stress that reduces growth and productivity of different crops. In many agricultural soils cyanobacteria or blue green algae are the prominent inhabitants, where they potentially contribute to improve soil fertility and crop productivity under normal and abiotic stress conditions. Glycinebetaine is an osmoprtectant compound improving plant tolerance to abiotic s...

Understanding the role of soil organic matter (SOM) in soil quality and subsequent crop yield and input requirements is useful for agricultural sustainability. SOM is widely considered to affect a wide range of soil properties, however, great uncertainty still remains in identifying the relationships between SOM and crop yield due to the difficulty in separating the effect of SOM from other yie...

BACKGROUND Vrikshayurveda, an ancient science of plant life described by Surapala, deals with healthy growth and productivity of plants, which has clearly outlined a systematized agricultural practice that insisted the use of Kunapa jala (KJ) and Pancha gavya (PG). OBJECTIVE An experiment was conducted to validate KJ and PG by nutrient analysis and their effect on the germination parameters o...

The nutrient contents of a widely-consumed leafy vegetable produce – Telfairia occidentalis using poultry manure (PM) and mineral fertilizer (Nitrogen, phosphorus and potassium-NPK) application were evaluated for comparison. PM at four levels (0, 5, 10 and 15 tonnes) and a standard rate of 90kg NPK per hectare was applied. Leaves were harvested for immediate analyses at 15 weeks after planting ...

Growth and biochemical performance of Manihot esculenta Crantz (TMS 0505) amended with Centrosema pubescens and NPK fertilizer were carried out. Contamination levels of 2%, 4%, and 6% were used while amelioration treatments C. pubescens and NPK 15:15:15 were carried out by adding organic supplement (decomposed Centrosema pubescens) and NPK at the rate of 0.25Kg per 5Kg of soil to the various le...

Greenhouse experiments were carried out for phytoremediation of the Pb/Zn abandoned tailings (pH 3.2 and high metal content) of Rampura-Agucha Mines, Rajasthan. Vigna unguiculata (L.) Walp. (cowpea) was chosen as a test crop. On unamended tailings, the seeds of the test plant showed no germination. The tailing was amended with lime (3% on weight basis), 3% lime + NPK (diammonium phosphate at 60...

an experiment was conducted in the experimental field of seed and plant improvement institute in karaj for three consecutive cropping seasons, 2001-2003, to study the effects of eight different fertilizer treatments including some microelements on grain yield and protein content of a bread wheat cultivar pishtaz. the experiment was in a rcbd with three replications.eight fertilizer treatments w...

In this study, waste water drains and produced phosphate fertilizers of conventional wet-process (hemihydrate) phosphoric acid and phosphate fertilizer plants were investigated to determine the average uranium contents in the active manufacturing period. The method chosen for the determination of uranium was an extension of an existing spectroanalytical method and was adopted for waste water an...

Soil organic carbon (SOC) sequestration is important for improving soil fertility of cropland and for the mitigation of greenhouse gas emissions to the atmosphere. The efficiency of SOC sequestration depends on the quantity and quality of the organic matter, soil type, and climate. Little is known about the SOC sequestration efficiency of organic amendments in Vertisols. Thus, we conducted the ...

A series of experiments was carried out at Students Farm, Sindh Agriculture University, Tandojam to evaluate the effect of NPK, micronutrients and N-placement on the growth and yield of sunflower during 2005-2006. The sunflower cv. HO-1 was studied under 7 different NPK levels and placement methods (0-0-0 NPK kg ha, 6030-30 NPK kg ha (N as broadcast), 60-30-30 NPK kg ha (N as fertigation), 90-4...
