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....

Aim: Many countries import potassic fertilizers due to dearth of K-mineral deposits. Therefore processes to obtain K-nutrient sources from sea bittern were developed by our Institute. The present investigation evaluated the fertilizer potential of three different sea bittern-derived (SBD) potassium forms developed viz., potassium schoenite, potassium nitrate and potassium ammonium sulfate on ma...

In recent years, the increase in grain yield under irrigated conditions has led to a decrease technological quality of grain. The main reason for this is lack nitrogen during formation wheat on gray soils with low humus content. Under conditions, one most urgent tasks winter and improve quality. According results scientific research, today absorbs 50-55% fertilizers, 20-22% phosphorus fertilize...

To investigate the interacting effects of polymer coated urea (PCU) and polymer coated potassium chloride (PCPC) on cotton growth, an experiment was conducted with containerized plants in 2014 and 2015. There were two kinds of nitrogen fertilizer, PCU and urea, which were combined with PCPC at three application rates (40, 80 and 120 kg ha-1). The kinds of nitrogen fertilizer formed the main plo...
