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. ...

What is the benefit of the oil press workshop?
Now is the peak season for the oil pressing industry. More and more oil pressing workshops purchase medium and large oil pressing machines, which obviously shows that the benefits of the oil pressing industry are very good. For oil press workshops, small machines, such as 6YL-95, can be considered when they are just starting to operate. This type of machine has lower cost, lower expenditure and ...

Bt-cotton and production risk: panel data estimates
The farm-level success of Bt-cotton in developing countries is well documented. However, the literature has only recently begun to recognise the importance of accounting for the effects of the technology on production risk, in addition to the mean effect estimated by previous studies. The risk effects of the technology are likely very important to smallholder farmers in the developing world due ...

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 ...

Optimizing Irrigation Efficiency with Smart Soil Sensor Systems
In the face of growing water scarcity and the pressing need for sustainable agricultural practices, optimizing irrigation efficiency has become a paramount concern for farmers worldwide. Traditionally, irrigation scheduling has relied on estimates and fixed schedules, often leading to overwatering or underwatering, resulting in wasted water, nutrient leaching, and reduced crop yields. The advent ...

Deficit irrigation optimization of cotton with aquacrop
Given the current pressures to reduce irrigation water use, it is important to optimize the use of water in irrigated agriculture. This work was aimed at determining the optimum level of applied irrigation water (AIW) for cotton (Gossypium hirsutum L.) production in southern Spain under several climatic and agricultural policy scenarios. To generate the yield response to variations in AIW, we ...

A comparison of two cotton cultivars differing in maturity for within-canopy fiber property variation
Improving uniformity in cotton (Gossypium hirsutum L.) fiber properties increases fiber processing performance. Our objective was to compare two cultivars differing in relative maturity for within-canopy variability of fiber physical properties and fiber surface chemical constituents. The cultivars (DPL 555 BG/RR [mid-full maturity] and PM 1218 BG/RR [early maturity]) were grown in plots on a ...

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 ...

Yield, quality, and fruit distribution in bollgard/roundup ready and bollgard ii/roundup ready flex cottons
New transgenic cotton (Gossypium hirsutum L.) technologies Bollgard II/Roundup Ready Flex (BGII/RRF) provide additional mechanisms for the cotton crop to retain early initiated fruiting structures positioned in the lower canopy. It may be possible, therefore, for early fruit retention to become too high with these new technologies resulting in early cutout and reduced yield. The objective of this ...

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 ...

Crop response to rotation and tillage in peanut-based cropping systems
Production of peanut (Arachis hypogaea L.) in reduced tillage systems has increased in the United States during the past decade. However, interactions of tillage system and crop rotation have not been thoroughly investigated for large-seeded, Virginia market type peanut. Research was conducted at two locations in North Carolina during 1999 to 2006 to compare yield of corn (Zea mays L.), cotton ...

Cotton subsurface drip and overhead irrigation efficiency, maturity, yield, and quality
Subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops. This study compared soil water, water use, crop maturity, lint yield, and fiber quality of cotton (Gossypium hirsutum L.) grown with SSD to cotton grown with overhead irrigation. Three experiments were conducted at two Georgia locations in 2004 and 2005. Treatments consisted of overhead irrigated, ...

How technology helps trace cotton from farm to consumer?
Cotton in numbers and why they matter Every year 27 million tons of cotton is produced globally and it is also the most often used natural fibre according to Statista. The WWF reports cotton production employs almost 7% of all labour in developing countries and provides income for over 250 million people worldwide. They also raise the concerns of the industry’s environmentally ...

Farming Cotton In A Water-Scarce World
One of the least discussed aspects of the climate emergency is the water crisis, but as the realities of water stress and scarcity around the world really start to bite, there can be no doubt that it will soon become a hot topic of conversation, hitting headlines with increasing regularity as time goes on. Because water underpins every aspect of society in the 21st century, it is immediately ...

Science’s role in growing diverse, nutritious food
Can science meet the demand for more diverse and nutritious food? Jan Piotrowski investigates. The riots that swept Africa in 2007 and 2008 in response to the spiralling costs of staple crops brought the effects of food shortages into sharp focus. Images of unrest circled the globe, and the consequent instability brought to the forefront of political debate a question that had long been out of ...

Analysis of trends in area, production and yield of important crops of India
Information related to trends in different crops can aid the policy makers in recommending policies leading to sustainable increase in the food production. The present study was aimed at analyzing the trends in area, production and yield of important crops viz. Cotton, Castor and Banana of India. A time series data from 2000-01 to 2011-12 (12 years) regarding the area, production and yield of ...
