A major challenge in rice (Oryza sativa L.) production is to enhance water use efficiency (WUE) and maintain or even increase grain yield. WUE, if defined as the biomass accumulation over water consumed, may be fairly constant for a given species in given climate. WUE can be enhanced by less irrigation. However, such enhancement is largely a trade-off against lower biomass production. If WUE is...

increasing attention has recently been given to sweet sorghum as a renewable raw material for ethanol production, mainly because its cultivation can be fully mechanized. however, the intensive use of agricultural machinery causes soil structural degradation, especially when performed under inadequate conditions of soil moisture. the aims of this study were to evaluate the physical quality of a ...

The relationships between densities of all members of a plant-parasitic nematode community and yield of 'Davis' soybean and between final and preplant population levels were examined in small plots on sandy soils in north-central Florida. Plant-parasitic nematodes present in the community included Belonolaimus longicaudatus, Criconemella sphaerocephala, Meloidogyne incognita, Paratrichodorus mi...

In the present paper, the distribution of solar energy inside the uneven span solarium has been determined in terms of solar fraction on north partition wall by using Auto-CAD 2000 for New Delhi (28.5° latitude). This enables the prediction of its performance for passive heating. The concept has been extended to other shapes of greenhouses for cultivation of flowers during off-season. The other...

Scabs caused by Venturia carpophila greatly reduce the quality of the fruits of the Japanese apricot (Prunus mume) when the disease is not properly managed. The disease produces a superficial blemish that is unlikely to affect the overall yield of processed fruit, but reduce the value of fruit intended for the fresh market. Incidence rates of scab at sprayed and unsprayed orchards range from 0%...

ABSTRACT Peanut cultivation has national and global significance in agriculture industry. Under water-limited conditions, its yield decreases to the extent that it compromises success of exploitation. This study focused on evaluating peanut crop production components under full deficit irrigation applied reproductive phase, determine impact water supply peanuts grown off-season State São Paulo,...

Life-history theory predicts that the trade-off between parasite defense and other costly traits such as reproduction may be most evident when resources are scarce. The strength of selection that parasites inflict on their host may therefore vary across environmental conditions. Collared flycatchers (Ficedula albicollis) breeding on the Swedish island Öland experience a seasonal decline in thei...
