The effects of chemical and organic fertilizers on saffron (Crocus sativus) were studied in a field experiment using a complete randomized block design with three replications at ferdowsi university of Mashhad. Fertilizers applied were N, P, K, NP, NK, PK, NPK, cow, sheep and chicken manure. The amount of chemical fertilizer applied were 50, 30, 30, 48, 48, 36, 66 kg/ha for N, P, K, NP, NK, PK,...
Due to high production of organic residues such as sewage sludge and compost, land application is probably the best way to prevent accumulated residues in the environment. However, the risk involved in the land application of organic residues should be evaluated prior to the assessment of their economic and fertilizer values. The objective of this study was to evaluate the effect of organic res...
Holstein cows housed in a modified tie-stall barn were used to determine the effect of feeding diets with different forage-to-concentrate ratios (F:C) on performance and emission of CH(4), CO(2) and manure NH(3)-N. Eight multiparous cows (means ± standard deviation): 620 ± 68 kg of body weight; 52 ± 34 d in milk and 8 primiparous cows (546 ± 38 kg of body weight; 93 ± 39 d in milk) were randoml...
AbstractYield of tea plant (Camellia sinensis L) is reduced in old farms due to the compactness of the soil around the roots. As a consequence, water flow and air exchanges will be reduced. Operating in the thin layer of soil where plant roots develop, earthworms improve recirculation of the nutrients and microbial metabolites and stimulate nutrient uptake. Evaluation of the biological effects ...
this study was conducted to evaluate the effect of fertilizers on the yield and essential oils of basil. this experiment was carried out in completely randomized block design with three replications in jiroft area. the treatments included three levels of barvar 2 (10, 20 and 25 g/ha), cow manure at three levels (5, 10 and 15 ton/ha), ammonium phosphate and superphosphate triple each at three le...
A field experiment was conducted to study the effect of different organic manures and their levels on nutrient status soil microbial activity in rose at Hisar during 2020-21. The treatments comprised 3 types viz., farm yard manures, vermicompost poultry manure 4 control, kg/m2, 5 kg/m2 6 kg/m2. carried out split plot design with three replications. Observation carbon, dehydrogenase alkaline pho...
A case study of the Central Vermont Public Service Corporation (CVPS) Cow Power program examines the economic feasibility for dairy farms to convert cow manure into electricity via anaerobic methane digestion. The study reviews the mechanism for CVPS, dairy farms, electricity customers, and government agencies to develop and operate the program since 2004, examines the costs and returns for the...
A study was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Bangladesh during April to September, 2012 to determine the suitability of selected plant growth regulators and the proper use and effectiveness of selected organic manures and also their suitable combinations for successful okra production. The experiment consisted of two factors: factor A: growth regulators...
