Harvesting green sugarcane with chopper harvesters results in up to 24 Mg/ha of post-harvest residue. Soil microorganisms can decompose residues and offer numerous ecological and economical benefits to growers; however, the process is dependent on the biotic density, diversity and activity in the soil. Further, the decomposition process is unfavourably slow such that sugar yields are adversely ...

Cues that have been paired with food evoke dopamine in nucleus accumbens (NAc) and drive approach behavior. This cue-evoked dopamine signaling could contribute to overconsumption of food. One manner in which individuals try to restrict caloric intake is through the consumption of foods containing artificial (non-nutritive) sweeteners. We were interested in whether cues paired with a non-nutriti...

In this study, eight transformed Solanum tuberosum L. plants, affected in their nitrate assimilatory pathway by the introduction of a tobacco nitrate reductase gene (Nia2), were cultivated in glasshouse conditions at INRA Ploudaniel (West Brittany, France). Two irrigation regimes were compared and plants were sampled at four stages of vegetation. Yield, tuber dry matter content, total nitrogen ...

The root weevil Diaprepes abbreviatus L. has been continuously reared since 1992 on an artificial diet (F1675) first reported in 1982. The weight of weevils reared on F1675 was more than twice as great as field-collected individuals. Recently, several ingredients included in the original F1675 diet were shown to have little or no effect on insect performance. We examined the effects of varying ...

I t has been reported earlier (Esh, De & Basu, 1959) that a 38 yo variation occurs in the protein content of the pulse, Bengal gram (Cicer arietinum), as a result of difference in genetic strain. Moreover, samples of Bengal gram were found to contain on the dry basis from 17.5 to 27.9 yo crude protein, when they were grown in different localities and from different strains (Esh et al. 1959). Va...
