A field study was conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semideterminate cowpea [Vigna unguiculata (L.) Walp.] genotypes developed in the Nigerian Sudan savannas in 1974 to 2004. Resul...

This paper fouses on the conservation and maintenance of agrobiodiversity of neglected and underutilized plant species, such as the African yam bean (Sphenostylis stenocarpa) in seed banks to contribute to food security and prevent a potential food crisis. The potentials and biodiversity of vario...

A simulation analysis was carried out using the InfoCrop-rice model to quantify impacts and adaptation gains, as well as to identify vulnerable regions for irrigated and rain fed rice cultivation in future climates in India. Climates in A1b, A2, B1 and B2 emission scenarios as per a global climat...

At the Colombian coffee growing area, between 1,000 and 2,000m elevation, experiments were carried out under field conditions on steep slopes at Romelia (2,500 mm rainfall and a Dystrandept type of soil), and at Supía (1,708 mm rainfall and a Eutrandept type of soil). The legumes (Centrosema macr...

The projected changes in planted area, yield per area, net exports/imports and prices for five major agricultural crops in South Africa were simulated using the projections of four Global Circulation Models (GCMs) under three socio-economic scenarios. The GCM projections show consistent strong wa...

Improved crop yield forecasts could enable more effective adaptation to climate variability and change. Here, we explore how to combine historical observations of crop yields and weather with climate model simulations to produce crop yield projections for decision relevant timescales. Firstly, th...

Approaches that can help reduce future water shortages and increase food production in the Mediterranean region include the capture of more rainwater and better use of scarce irrigation water. The objective of this study is to evaluate the additive effect of combining zero tillage, supplemental i...

Water deficit is the main yield-limiting factor across the Asian and African semiarid tropics and a basic consideration when developing crop cultivars for water-limited conditions is to ensure that crop water demand matches season water supply. Conventional breeding has contributed to the develop...

Within Colombia significant amounts of seed are produced and exported of the perennial tropical grasses; Brachiaria decumbens, Cenchus ciliaris, Dichanthium aristatum, Hyparrhenia rufa, Melinis minutiflora, and Panicum maximum. Small amounts of the perennial legume Pueraria phaseoloides are produ...
