Renewable energy generation has attracted growing interest globally. The agro-photovoltaic (APV) system is a new alternative to conventional photovoltaic power plants, which can simultaneously generate renewable and increase agricultural productivity by the use of solar panels on same farmland. optimization crop yields assessment their environmental sensitivity under have not yet been evaluated...

Objective: to establish that the price of main products Mexican agricultural sector are cointegrated with production producing States five regions sector.
 Design/methodology/approach: thirty cointegration tests were carried out determine if prices influence Mexico Mexico, which grain corn, sorghum and bean.
 Results: in northwest region, does not beans; In northeast, central-western ...

With approximately 11 million habitants, Guatemala is mostly a rural country, with 60 percent of the population living on farms and 50 percent of the population indigenous. Maize and beans are the main staple food in most households, with a per capita consumption of 9.4 kg per year. Since few other sources of protein are available, this amount is not sufficient to ensure an acceptable nutrition...

In arid and semi-arid regions, where precipitation is low or infrequent during the dry season, it is necessary to store the maximum amount of rainwater during the wet season for use in the agriculture sector. Rainfall in the Kingdom of Saudi Arabia takes place primarily during winter and spring seasons. The amount of rainfall ranges from 0.1 to 0.2 m in the area extending from north of Riyadh t...

Materials and Methods The Neely-Kinyon LTAR site was established in 1998 to study the long-term effects of organic production in Iowa. Treatments at the LTAR site, replicated four times in a completely random design, include the following rotations: conventional Corn-Soybean (C-S), organic Corn-Soybean-Oats/Alfalfa (C-S-O/A), organic Corn-Soybean-Oats/Alfalfa-Alfalfa (C-S-O/AA), and Soybean-Whe...

The nucellus is a complex maternal grain tissue that embeds and feeds the developing cereal endosperm and embryo. Differential screening of a barley (Hordeum vulgare) cDNA library from 5-d-old ovaries resulted in the isolation of two cDNA clones encoding nucellus-specific homologs of the vacuolar-processing enzyme of castor bean (Ricinus communis). Based on the sequence of these barley clones, ...

The objective of this study was to improve the seed production Volvariellavolvaceain Daloa(central-west Cote dIvoire). Tissue fragments were cultured on PDA (Potato Dextrose Agar)medium for mycelium. Once mycelium obtained, it inoculated into jars containing pre-cooked cereals (maize, sorghum) and legumes sterilized (at 121°C). When are completely covered with mycelium, different parameters me...

Histone proteins were studied by microphotometry of plant tissue sections stained with fast green at pH 8.1. For comparative purposes the Feulgen reaction was used for deoxyribose nuclei acid (DNA); the Sakaguchi reaction for arginine; and the Millon reaction for estimates of total protein. Analysis of Tradescantia tissues indicated that amounts of nuclear histone fell into approximate multiple...

2,4-Dichlorophenoxyacetic acid (2,4-D) is the best known selective herbicide for effective control of broadleafed weeds in monocotyledonous crops. Although the mechanisms by which 2,4-D acts on plants have not been elucidated, several lines of investigation have shown: A. Stimulatory and inhibitory effects on the respiration of pea and oat tissues, depending upon the concentrations employed (6)...
