The coastal saline soils, Kharlands, have great potential for their use in aquaculture. This study has been taken up to understand the limnology of the ponds in Kharland area for assessing their prawn culture potential. This study was carried out during September, 1999 to August, 2001. Each Kharland pond has an area of 0.045 hectare. During the study, depth of pond water was 47.7 to 120.0 cm, t...

Abstract The impact of using chemical fertilizers in the cultivation system changes soil’s physicochemical characteristics. Local resources-based amelioration technology can be used as a solution to increase soil fertility and plant productivity. This study aimed measure properties Inceptisols monoculture polyculture systems. A randomized block design was this research with eight treatments thr...

The effects of prolonged photoperiod (additional night lighting) were investigated on the production Ocimum basilicum (lemon basil) and fish/crayfish raised in a nutrient film technique aquaponic system. Hybrid lemon fin barb red claw crayfish juveniles co-cultured with O. subjected to 12 h ambient natural daylight additional 0, 4, 8, lighting for 14 weeks (two batches 7 each). water quality pa...

• We enumerated arbuscular mycorrhizal (AM) fungal spore communities for 3 yr as part of a long-term CO 2 enrichment experiment at Cedar Creek, Minnesota, USA. Complete factorial combinations of two levels of CO 2 and N, and 16 perennial plant species grown in monoculture and 16-species polyculture were arranged in a splitplot design. • In 1998–2000, spore communities were quantified under mono...

Nitrogen (N) fertilization can greatly improve plant productivity but needs to be carefully managed to avoid harmful environmental impacts. Nutrient management guidelines aimed at reducing harmful forms of N loss such as nitrous oxide (N2O) emissions and nitrate (NO3(-)) leaching have been tailored for many cropping systems. The developing bioenergy industry is likely to make use of novel cropp...
