Equivalency of broiler litter to ammonium nitrate as a cotton fertilizer in an upland soil
Estimates of litter value based on crop yield equivalency to inorganic fertilization may reflect the actual value of litter more accurately than estimates based on its N, P, and K content. The primary objective of this research was to identify a rate of broiler litter that results in cotton lint yield equivalent to inorganic N fertilization and to estimate litter value based on this yield ...

Cotton yield responses to fertilizer Nitrogen rates in a cotton-corn rotation
The amount of N fertilizer needed for optimal cotton (Gossypium hirsutum L.) yield in cotton-corn (Zea mays L.) rotations should be established to enhance the agronomic, economic, and environmental sustainability of crop rotations in the mid-southern United States. Nitrogen rates were evaluated in field studies from 1996 through 2001 on Commerce silt loam (SL) (fine-silty, mixed, nonacid, thermic ...

No-till and conventional-till cotton response to broiler litter fertilization in an upland soil: lint yield
The effectiveness of poultry litter as cotton (Gossypium hirsutum L.) fertilizer is not well documented for upland soils in the southern and southeastern United States. The objective of this research was to measure cotton yield response to broiler litter fertilization in contrast to inorganic N fertilization and to quantify yield reduction due to lack of incorporation under no-till and ...

Accounting for adaptation in assessing impact of climatic variations on crop yields: an empirical study of Arizona
The goal of this paper is to analyze the impacts of climatic variation around current normals on crop yields and explore corresponding adaptation effects in Arizona, using a unique panel data. The empirical results suggest that both fertilizer use and irrigation are important adaptations to climate change in crop production. Fertilizer use has a positive impact on crop yields as expected. ...

Timing of maturity in ultra-narrow and conventional row cotton as affected by nitrogen fertilizer rate
Ultra-narrow row (UNR) systems and N fertilizer can influence cotton (Gossypium hirsutum L.) crop maturation. Study objectives were to measure impacts of UNR systems and N fertilizer rates on cotton maturation and to identify mechanisms by which these effects occurred. The location was Burleson County, Texas. In the split plot design, whole plots were N rates of 0, 50, 101, and 151 kg ha–1. Split ...

Nitrogen storage with cover crops and nitrogen fertilization in tilled and nontilled soils
Improved crop and N management practices are needed to increase soil N storage so that N fertilization rate and the potential for N leaching can be reduced in tilled and nontilled soils. We examined the influence of cover crops and N fertilization rates on N inputs from cover crops, cotton (Gossypium hirsutum L.) and sorghum [Sorghum bicolor (L.) Moench] and soil total N (STN) content at the 0- ...

Nitrogen mineralization in a pecan ( Carya illinoensis K. Koch)–cotton ( Gossypium hirsutum L.) alley cropping system in the southern United States
Information on temporal and spatial patterns of N mineralization is critical in designing tree-crop mixed systems that could maximize N uptake while minimizing N loss. We quantified N mineralization rates in a pecan (Carya illinoensis K. Koch)–cotton (Gossypium hirsutum L.) alley cropping system in northwestern Florida with (non-barrier) and without tree-crop belowground interactions (barrier ...

A target region amplified polymorphism marker for fertility restorer gene rf1 and chromosomal localization of rf1 and rf2 in cotton
Cytoplasmic male sterility (CMS), a maternally inherited trait characterized as an inability to produce functional pollen, is an important biological system for economically producing hybrid seed to enhance crop yield and studying cytoplasmic and nuclear gene interactions. In cultivated tetraploid cotton (Gossypium hirsutum L.), male fertility in two systems CMS-D2 and CMS-D8 is restored by two ...

Nutrient dynamics from broiler litter applied to no-till cotton in an upland soil
Applying broiler litter to the soil surface of a no-till field of cotton (Gossypium hirsutum L.) increases the potential loss of its nutrients via runoff and volatilization. An experiment was conducted over 3 yr on an upland Atwood silt loam soil (fine-silty, mixed, semiactive, thermic Typic Paleudalfs) near Pontotoc, MS, to determine the effect of broiler litter incorporation into the surface ...

One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas
All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the world’s agriculture is grown in areas of high water stress. This figure doubles when looking at irrigated cropland, which produces 40 ...

Indigo`s Living Map of the World`s Food System
Two weeks ago, at the inaugural Beneficial Ag event in Memphis, Indigo was proud to participate in a growing community of innovators from across the food system. One of the questions we asked ourselves was, “What are the technological capabilities needed to catalyze the beneficial agriculture movement?” We believe a new way for seeing the global food system is part of what’s ...

Farmers fine-tune research, spread their own innovations
Smallholder farmers can aid the uptake of research fruits and drive grassroots innovations. Joel Winston reports. The 1960s' Green Revolution demonstrated how technological innovations can transform agriculture. High-yielding crop strains, irrigation, fertilisers and pesticides were brought into developing countries, including India and the Philippines, increasing yields by more than 250 per ...

Composting cotton industry by-products. Evaluation of Use of cotton solid wastes compost as a substrate.
The textile industry at region of Entre Douro e Minho is located at Ave valley and is responsible for a great amount of cotton solid wastes. Currently these wastes, which are characterised by a high C/N ratio and some salinity, are directly applied to soil by farmers without any previous treatment (Zucconi et al, 1981). Extraction of peat causes environmental damage (Smith, 1992) which leads to ...
