The study aims to determine the effect of applying for intercropping food crops (rice, corn, and soybeans = jagole ) on cropping index income urban farming community activists. This was conducted by comparing use six models growing crops, namely three kinds monoculture model , upland rice-soybean, sweet corn-soybean, corn-upland rice polyculture/ “ Turiman ”. Observational data includes land ch...

This study incorporates the application of a linear programming technique for composition fish feed mixture to minimize cost without sacrificing nutrients levels. Designing best diet fry, fingerling, and growth stages is main goal this study. Regarding nutrient manufacturing costs, study's results show that variety elements can be combined much more effectively than in commercially available fe...

Abstract The Mahakam Delta is a large mangrove ecosystem in East Kalimantan with precious and massive species. Because of the conversion to shrimp aquaculture, has been devastated. This study looks at pond management Salo Palai, Muara Badak, Kutai Kartanegara, Kalimantan, using traditional polyculture concept increase productivity. current condition was decreased water quality, substrate infert...

Mixed cropping, also known as inter-cropping, polyculture, or co-cultivation, is a type of plant production system that involves planting two more species (or cultivars) simultaneously in the same field variable order (row rowless) [...]

Alternative polymer-based filter media and ornamental plants in constructed wetlands (CWs) are a relatively unexplored field. These approaches have the potential to reduce construction costs enhance aesthetic appearance of CWs. This study evaluated for first time use as monoculture polyculture, well incorporation polyethylene terephthalate (PET) medium large-scale community HC (divided into 12 ...

the objective of this study was to compare growth performance and feed conversion ratios of rainbow trout (oncorhynchus mykiss) and brook trout (salvelinus fontinalis) juveniles in monoculture and duo-culture in freshwater and seawater under aquarium conditions. the fish were about 2-months old hatchery-reared brook and rainbow trout with initial weights of 0.934±0.033 (n=360) and 1.014±0.019 (...

: The present study aimed to determine both the effects of monocultures rainbow trout (R) and brown (B) polycultures (R 75%-B 25%; R 66%-B 34% 50%-B 50%) on behavior. In study, area used vertically by fish in tank, mobility rate tendency eating as soon they were fed, whether test feed, interspecies feed competition, time start take first duration consumption have been considered behavioral eval...

Polyculture farming is an agricultural practice of growing several types crops on the same land.The sustainability polyculture influenced by presence insects, both ecologically beneficial and detrimental. In ecology, insects have important role as pollinators, predators, pests that significantly affect health crops, including in farms. As effort for sustainable management, especially pest contr...

From 2012 to 2015, we investigated methane (CH4) distribution, air−sea fluxes, and sediment−water fluxes in an aquaculture bay (Sanggou Bay, China), and estimated the input of CH4 from potential land sources including rivers and groundwater. Surface water CH4 in the bay ranged from 3.0 to 302 nM, while bottom CH4 was usually higher due to sediment release. Water column CH4 in summer and autumn ...

The research investigated the impacts of inclusion of column feeder rohu (Labeo rohita) on growth and production in freshwater prawn-carp-mola polyculture system for a period of 172 days. Four stocking densities of Rohu were maintained as 500, 1,000, 1,500 and 2,000 ha -1 in treatment R500, R1000, R1500 and R2000, respectively in triplicates. All ponds each 120 m 2 were stocked with juvenile fr...
