A field experiment was conducted on deep vertisols of Bhopal, India to evaluate the manural potential of three organic manures: farmyard manure (FYM), poultry manure (PM), phosphocompost (PC) vis-a-vis 0%, 75% and 100% recommended dose of fertilizer-NPK and to find out the most productive cropping system at various combinations of organic manures and chemical fertilizers. The seed yield of inte...

In order to evaluation effect of different level of humic acid affected drought stress on seed yield, its components and morphological traits of corn a research farm was conducted according split plot experiment based randomized complete blocks design at three replication during 2015 year. Main factor included four irrigation regimes (90mm, 110 mm, 130 mm and 150mm evaporation from pan class A)...

Pig manure is an excellent fertilizer and rich source of organic carbon and nitrogen compounds such organic nitrogen (O-N) (95% of total nitrogen) that is plant-unavailable-nitrogen (PUN) and mineralized nitrogen (about 1% of total nitrogen) such as ammonium (NH4+) and nitrate (NO3) that are plant-available-nitrogen (PAN). In addition, manure also contains two forms of estrogens: (i) poorly est...

This study investigated the optimum mixture ratio of greenhouse tomato plant residues, wheat straw, and separated dairy manures for composting. Five 127-L laboratory-scale bioreactors were used to investigate the effect of separated dairy manure addition on the composting process of a tomato plant residues-wheat straw mixture. The wastes were mixed at 5 different ratios during the trials and we...

Crop production by the use of sustainable methods in agriculture has become the order of the day as there is a growing concern to conserve the environment and make the earth last longer for posterity. Keeping this end in view there is a constant search for manures and fertilizers that are eco-friendly and biodegradable. Vermicomposting is a novel method of decomposing organic matter and produci...
