The present study was undertaken to develop potassium management recommendations that maximize yield and post harvest quality of tomato. Studies were conducted at Faculty of Agriculture, Gomal University, Dera Ismail Khan, KPK, Pakistan during 2008-2009. A pot experiment was designed, which included six potassium fertilizer treatments (75, 150, 225, 300, 375, 450 Kg K2O ha ) with basal doses of...

Organic waste materials are being used in huge amounts (tons ha) for improving soil health and crop yields. Recycling of organic wastes enriched with nitrogen and L-tryptophan (L-TRP) could convert organic waste material into a useful soil amendment, which may be effective even when added in substantially small amounts (kg ha). Organic waste material of fruits and vegetables was collected and s...

The performance of canola (Brassica napus L.) was evaluated using various nitrogen levels and shoots cutting at New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during Rabi 2012-13. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement having four replications each. Nitrogen levels @ 0, 50, 75 and 100 kg ha were allotted to...

introduction: in iran, tuberose is ranked the forth after gladiolus, rose and carnation. these flowers are known as high quality products among which maximum exportation belongs to tuberose and gladiolus. in plant cultivation and development, adequate provision of nutrients is of crucial importance. tuberose needs plenty of nutrients to obtain the desirable quality and flowering. hence, tuberos...

Von Liebig noted in his most famous book that agriculture’s principal objective is the production of digestible N (1). This task was particularly challenging in all traditional (pre-industrial) agricultures. They had 3 ways in which to provide N for crops: i) recycling of organic wastes (mainly crop residues and animal and human wastes); ii) crop rotations including N-fixing leguminous species;...

background: alpha methyldopa (amd) is a well-known treatment for the pregnancy induced hypertension and commonly used in several countries. indeed the possible effect of amd on the behavioral activities of offspring, whom are exposed during fetus period, has not been studied. the present study evaluated the possible effect of maternal administration of amd on the rat offspring memory in the gro...

Quantification of the Nitrogen (N)-supplying capacity of organic manures provides an important insight into more effective N management practices. The aims of this study were to determine the potential N mineralization of cow manure (CM), poultry manure (PM), urea fertilizer (UF) and the combined use of cow manure + urea fertilizer (CM + UF) for silage maize (Zea mays L.) in a calcareous so...

in order to study the effects of plant density and nitrogen rates on yield, nitrate and protein of silage maize (ksc 704) in shahrekord area, an experiment was conducted during 2007 growing season at the agricultural research farm of shahrekord university. the experimental design of the experiment was randomized complete blocks with factorial arrangement with four replications. treatment consis...
