This study was carried out in the University of Benin, Benin City, Nigeria, from June to August, 2013. Three organic manures (poultry manure collected a poultry farm Benin; pig Ugbighokho, Upper Ekehuan road and cow dairy located at Technical College road, all Nigeria), were used for study. Exposure done day after collection evaluation made daily ascertain each various developmental stages appe...

This study was conducted to evaluate the performance of black gram (Vigna mungo.L) grown under drought stress using coir waste manure and cow dung manure. Two varieties of black gram-ATD mash 3 and ATD mash 1 were the treatment variables. A best fit positive relationship existed between leaf chlorophyll and leaf nitrogen content with two organic manures. N, P and K accumulation in the two varie...

Soil acidity, which is characterized by mainly aluminum (Al) toxicity and often calcium (Ca) deficiency, is a serious constraint for crop production in many regions of the world. Soil acidity is traditionally corrected by applications of lime (CaCO3 or Ca(OH)2), which raise soil pH, precipitate Al and provide Ca. However, high rates of lime cannot be afforded because of its high cost relative t...

Integration of cover crops into arable rotations over winter results in difficulty determining the nitrogen (N) requirement for following commercial crop. The region Northern Ireland (NI) has had no previous field research on and how they may affect N supply to Stubble turnips (Brassica rapa oleifera L.) were sown as a crop, after harvest barley (Hordeum vulgare retained winter. Prior planting ...

To produce hydrochar with less volatile matter (VM) and more fixed carbon (FC) to increase its stability, this study compared the hydrothermal carbonization (HTC) of hen (HM) swine (SM) manures at typical HTC sub-critical temperature 210 °C slightly super-critical 400 °C. Physico-chemical properties such as proximate analysis; ultimate Brunauer–Emmett–Teller (BET) surface area; higher heating v...
