net-screen covered greenhouses operating on natural ventilation are used as a sustainable approach for closed-field cultivation of fruits and vegetables and to eliminate insect passage and the subsequent production damage. the objective of this work was to develop a real-time assessment framework for evaluating air-temperature inside an insect-proof net-screen greenhouse in tropical lowlands of...

three experiments of 60 days duration were conducted in post larval stage of indian white shrimp, fenneropenaeus indicus, to explore the appropriate protein: lipid ratios in their diets. a common ingredient mixture consisting of; fish meal, shrimp meal, ground nut oil cake, cholesterol, lecithin, vitamins and minerals blended with chicken egg albumin, tapioca flour and cellulose (filler) was us...

the present study investigated the effects of prebiotic (α-mune), a mixture of mannan oligosaccharide, β-1,3 and β-1,6 glucan, on the growth performance, haematology and innate immunity of beluga sturgeon ( huso huso ) juvenile. fish (46±3 g) were allocated into 12 tanks (15 fish per tank) and triplicate groups were fed a control diet or diets containing 1.5, 3.0 and 4.5 g kg -1 prebiotic for 4...

the effects of arbuscular mycorrhizal (am) fungi on growth and phosphorus (p) inflow into two species of clover plant with different root morphology were studied. the experiment was arranged as a randomized complete block design consisting of a 2×3×3 factorial combination of two clover species (trifolium alexandrinum l. and trifolium pratense l.), three mycorrhiza states (without mycorrhiza, gl...

this experiment was conducted to study the effect of dietary n-3 to n-6 ratio on performance, immune response, blood parameters and fatty acids profile of broiler chickens. a total number of 192 one day old broiler chicks were randomly alloctted into 6 groups. chicks of groups 1, 2, 3, 4, 5 and 6 were fed balanced corn-soybean diets containing n-3 to n-6 ratios of 1:1, 1:3, 1:5, 1:7, 1:9 and 1:...

conclusions we found ccd and rsm very effective in optimizing hib culture conditions, and hib biomass production was greatly influenced by ph and incubation temperature. therefore, optimization of the growth factors to maximize hib production can lead to 1) an increase in bacterial biomass and prp productions, 2) lower vaccine prices, 3) vaccination of more susceptible populations, and 4) lower...

industries in developing countries add new production lines producing altogether different waste stream. this newer waste invariably finds its way to existing anaerobic treatment system causing gradual/sudden change in feed substrates affecting its steady performances. this study investigates steady response of anaerobic reactors subjected to sudden change in feed substrate types, assesses its ...

gerbera jamesoniiis of commercial significance and fifth most used cut flower in the world today. a pot experiment was performed to see the effect of co-inoculation of arbuscular mycorrhizal fungi (amf) i.e. (glomus mosseae andacaulospora laevis) with phosphate solubilizing bacteria pseudomonas fluorescensin the presence of different doses of superphosphate (low, medium, high) on growth establi...
