Abstract:
... Given a rising demand for quality assurance, rather than solely yield, supplemental irrigation plays an important role to ensure the viability and profitability of vegetable crops from unpredictable changes in weather. However, under drought conditions, agricultural irrigation is often given low priority for water allocation. This reduced water availability for agriculture calls for techniques wit ...

Abstract:
... Zebra chip (ZC) of potato is putatively caused by the fastidious, phloem-limited bacterium ‘Candidatus Liberibacter solanacearum’ (Lso), which is transmitted by the potato psyllid (Bactericera cockerelli). The disease, which significantly impacts both crop yield and quality, was first identified in the United States from south Texas in 2000. It reached epidemic levels in north Texas and certain pr ...

Several questions arise regarding these applications, such as what are the most appropriate rates, whether to split the rates between the phenological stages, and what is the most efficient method to apply P. Nutrients can be either knifed into th ...

Abstract:
... The protein quality of maize (Zea mays L.) can be improved by replacing normal Opaque2 alleles with nonfunctional recessive alleles (o2). Homozygous o2 kernels have increased levels of lysine and tryptophan. Unfortunately, the associated soft texture of the o2 kernels causes poor yield and susceptibility to diseases and insects. Breeding has resulted in the development of o2 genotypes with improve ...

Abstract:
... Salinity of irrigation water reduces yield and juice quality in sugarcane (Saccharum spp. hybrids), but cultivars vary in the degree of reduction. Genotypes which accumulate more potassium (K+) may be more resistant to salinity than genotypes that accumulate less K+. We examined the effect of irrigation water salinity on yield and juice quality in a cultivar with high conductivity, high K+ juice, ...

Abstract:
... Nitrogen fertilizer recommendations have been developed for sugarcane (Saccharum officinarum L.) based on numerous fertility trials, with the primary variables affecting those recommendations being soil type and crop age. Cropping history influences subsequent crop responses to N fertilization, but such effects have not been determined for sugarcane. The objective of this research was to evaluate ...

... Prediction of animal weight change (CUM) with regression models developed from grazing trials typically uses herbage parameters and CUM measured on the same day. We hypothesized that lamb (Ovis aries L.) CUM recorded at time t was a function of herbage quality and/or quantity measured at a previous harvest t − x (where x = days prior to measurement of CUM). Our objectives were (i) to determine if ...

Speckback, a small imperfection that occurs on the dorsal surface (the surface opposite the germ) of kernels of rice (Oryza sativa L.), is characterized by a variety of lesions, not all of which are discernible by the unaided eye and, therefore, are unlikely to be detected by inspectors in industry. Speckback has been known for years but was so rare and inconspicuous that it was not considered a p ...

Tests were conducted for 3 yr (1982–1984) on a Beaumont clay soil (Entic Pelludert) to evaluate 12 rice cultivars under flood and three levels of sprinkler irrigation. Plant growth (height), plant development (days to heading and harvest), yield, yield components, and quality were monitored. Irrigation ...

The objective was to determine if N response is dependent on the amount of seasonal irrigation. Sugarbeet root yield, fresh weight sucrose concentration, and impurities were measured in experiments involving four N rates within three irrigation levels during 1982, 1 ...
