to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...

Soil amendment with organic materials (crop residues animal manure, and green manure) reportedly has positive effects on soil properties, from acidity to plant-nutrient availability. To examine that hypothesis, an incubation study was conducted to assess the changes in some chemical properties of three different tropical soils (Andisol, Ultisol, and Oxisol) amended with chicken manure and green...

Anaerobic digestion is one of the most widely used treatment methods for animal manure. Chicken manure has high methane production potential and thus a suitable substrate biogas plants. However, nitrogen content inhibits metabolism anaerobic microorganisms hinders from chicken Enhancing performance indeed long-standing challenge. This review presents new insights into maintaining methanogens’ a...

Little attention has been paid to the environmental fate of the hormones 17beta-estradiol and testosterone excreted in animal waste. Land application of manure has a considerable potential to affect the environment with these endocrine disrupting compounds (EDCs). Composting is known to decompose organic matter to a stable, humus-like material. The goal of the present study was to quantitativel...

Due to an increasing demand of leaf vegetables, and hence their economic importance in the tropics, it is very common that excessive fertilizer N rates are applied to vegetable gardens and fields to attain high yield. This calls for more information on their nutrient requirements. In this study, we designed experiments to explore the effect of organic N levels on the yield and agronomic N use e...

Bio-organic fertilizers (BOFs) combine functional microbes with a suitable substrate and have been shown to effectively suppress soil-borne diseases and promote plant growth. Here, we developed a novel bio-organic fertilizer (BOF) by fermentation of a cow plus chicken manure (M) compost using Fen-liquor Daqu (FLD) as a fermentation starter and compared the compositions of bacterial and fungal c...

Considering the constraints due to unavailability of uniform quality chicken manure in local market, three different combinations of wheat and soyabean meal (de-oiled cake) were tested for their ability to affect yield and cost of production of Button Mushroom (Agaricus bisporus). Compost was prepared by mixing 18, 22 and 25% soyabean meal with wheat straw by short method of composting. 80% chi...

Cassava peel based substrate formulations as an alternative substrate were used to grow mushrooms. The effect of two compost heights, three composting periods on the mycelia growth, physical characteristics, yield, and nutritional qualities of Pleurotus ostreatus (Jacq. ex Fr.) Kummer was studied. Mean mycelia growth of 16.2 cm after a period of seven (7) weeks was the best for 1.5 m compost he...

Effects of high temperature pretreatment and inoculation Bacillus coagulans were determined relative to the physicochemical properties bacterial community aerobic composting chicken manure. Chicken manure was pretreated with for 0 h (CJ), 0.5 (T-0.5h), 1.0 (T-1.0h), 1.5 (T-1.5h), 2.0 (T-2.0h) then inoculated B. coagulans. without included as control (CK). The results showed that in CJ, T-0.5h, ...
