Technical efficiency of maize production in Northern Ghana

The ability of maize farmers in Ghana to increase yield levels and attain sustainable production depends on efficient farm practices, hence technical efficiency. This study applied the stochastic frontier methodology to examine the technical efficiency of maize production for the 2011/2012 cropping season. Multi-stage sampling procedure was used to obtain 360 maize households for the study. The determinants of maize...

The competitiveness of the Saudi Arabian date palm: An analytical study

The Kingdom’s date production has not kept pace with export activities, where the demand of foreigners as workers or visitors in KSA is increased from year to other, so as the percentage of exports is about 6.8% of the domestic production, which is equivalent to 8.7% of the global exports, moreover, the average price of export reached 1065 US$/ton. The low export price of Saudi dates is attributed to the lack of...

Effect of interception by canopy in the IDF relation (rainfall intensity, duration and frequency) in a semiarid zone

This study has been developed on a semiarid zone located in Mexico; the objective of this research is to measure rainfall interception, and to evaluate the effect of interception in intensity, duration, frequency curves. The rainfall interception was determined from rainfall simulation at several intensity levels on grass covered vegetation samples taken from experimental zone, where income precipitation, runoff, change...

Competition and facilitation-related factors impacts on crop performance in an agro-forestry parkland system in Burkina Faso

Parkia biglobosa and Vitellaria paradoxa are known to improve soil fertility and redistribute water under their crowns in parkland systems. A field experiment was conducted to separate above and belowground interactions between these species and associated Sorghum bicolor using root trenching and crown pruning during three cropping seasons. Trenching increased soil water availability...

Genotypic variation in yield in wheat to cold sensitive response at high altitude

Low temperature becomes an important limitation for production of grains in wheat cultivars as altitude increases. An alteration of growth habit accompanied with changes in morphology of leaf, shoot and root characteristic and cool temperature induced sterility in florets seemed to be associated with yield loss. The extent of variability of these characters, their relationship and contribution to grain yield were...

Evaluating the effect of aflatoxin food safety concerns on Iran’s pistachio trade with gravity model

How food safety affects international trade is an important factor to be studied for low-income countries which continue to rely on agricultural exports. Iran, as the greatest pistachio exporter in the world, encounters a  serious problem of aflatoxin contamination. This food safety shocks affected Iran’s  income which has  caused a lot of damages to  the country’s economy. The paper...

Acclimatization of micropropagated Musa cavendischii cultivar roatan plants submitted to doses of fertigation and auxin

Micropropagation of banana is suggested to produce great number of healthy plants but the success depends on the ability to transfer plants from in vitro conditions to greenhouse or field environment, at low cost and with high survival rates. In this study, the effects of the fertilization and indolebutyric acid (IBA) applied in the nutritive solution on growth of Musa cavendischii plantlets were evaluated during...

Relationships between the physiological and biochemical modifications in soybean seeds under different temperatures

The aim was to analyze the effect of the stress caused by different temperatures, for a period of 24 h, on seed germination and initial growth of soybean seedlings to relate these variables with the antioxidant defense system. For this, three seed lots were exposed for 24 h at temperatures of 15, 25, 35 and 40°C, being evaluated for germination, first germination counting (FGC), germination speed index (GSI),...
