Single crystalline Tl2Ba2Ca2Cu3O10 was studied using electronic Raman scattering. The ̋renormalization of the scattering continuum was investigated as a function of the scattering geometry to determine the superconducting energy gap 2∆( $ ) k . The A1gand B2g-symmetry component show a linear frequency behavior of the scattering intensity with a peak related to the energy gap, while the B1g-symme...

High input costs and poor management options have resulted in a large rice yield gap. Thus, there is need to reduce production improve resource-use efficiency by using new cultivation techniques at different locations. The objective of this study was determine utilization gaps early maturing japonica under four treatments; no nitrogen application (N0), local farmer practice (FP), high-yield, hi...

Under drought, substantial genotype-environment (G x E) interactions impede breeding progress for yield. Identifying genetic controls associated with yield response is confounded by poor genetic correlations across testing environments. Part of this problem is related to our inability to account for the interplay of genetic controls, physiological traits, and environmental conditions throughout...

46 (eds M.C.S. Wopereis et al.) wateror nutrient-limited production levels in a given rice environment. Yield-reducing factors induce yield losses by reducing or hampering growth, including abiotic and biotic factors. Biotic factors include weeds, pests and diseases; abiotic factors include salinity, alkalinity and iron toxicity. Attainable yield (Ya) refers to the yield that can be achieved wi...

Ghana is the second largest producer of cocoa in world and farming supports livelihoods 25-30% Ghana's population. However, average yield only about 30% potential yield. Cocoa farms established on recently cleared rainforest are initially productive, but then productivity declines as soils become depleted nutrients. Further expansion cultivated land by deforesting tropical rainforests environme...
