A study on tick borne infections of cattle in Yola locality of Adamawa State

Blood samples were collected and examined for haemoparasites from 1530 cattle composed of four breeds: Adamawa gudali (434), Sokoto gudali (386), Red bororo (414) and Bunaji (298). Six hundred and forty (41.8%) of those examined were infected with haemoparasites. Three species of tick-borne parasites were encountered namely Babesia bigemina, Theileria parva and Anaplasma marginale and a non-tick borne...

Relationship between litter size and parity of doe in smallholder goat herds in Kano and its environs, Nigeria

The parity and litter size of 116 does from 22 randomly selected herds were surveyed to determine the relationship between herd size, parity and litter size of smallholder goat herds. The study revealed that the average parity and litter size of smallholder goat herds was 2.7 and 1.7, respectively with a herd size of 15.0 goats. Majority of the breeding does were within the herd size of 11 to 20 goats (53.4%) followed...

Genetic diversity of honey bee (Apis mellifera L.: Hymenoptera: Apidae) populations in Turkey revealed by RAPD markers

The honeybee, Apis mellifera L. is an ecologically and economically important insect species. Recent honey bee losses causing decline of bee diversity is found alarming for the pollination of both wild plant biodiversity and crop production.  Therefore, determination of genetic diversity of honey bee populations is essential and will provide a valuable resource for conservation purposes. Twenty Random...

Effect of nitrogen foliar application on grain filling rate and period in 3 cultivars of corn (Zea mays L.)

In order to study the effect of nitrogen foliar application on seed rate and filing period in three cultivars of corn, a complete randomized block design base split plot experiment with three replications was conducted during 2009 at Agricultural Research Station, Islamic Azad University, Tabriz branch, Iran. Cultivars were arranged in three levels: early maturing (KSC307), average maturing (Jeta), and late maturing...

Late harvest associated with P and S fertilization enhances yield and quality of forage sorghum (Sorghum bicolor (L.) Moench), grown as a rainfed crop in Pakistan

To investigate the effect of harvest time associated with P and S fertilization on yield and quality of forage sorghum (Sorghum bicolor (L.) Moench), grown as a rainfed crop in Pakistan, a field study was carried in summer 2009. Three levels of phosphorus (0, 30 and 60 kg P2O5 ha-1), in combination with three levels of sulphur (0, 20 and 40 kg SO4 ha-1), in combination with three harvest times (35, 45 and...

Combining ability for morphoagronomic traits in common bean and snap bean

The present study aimed to estimate the combining ability for agronomic traits of interest in genotypes ofPhaseolus vulgaris by means of the Griffing diallel. To this end, six parents were crossed in a complete diallel scheme without reciprocals, namely, two common bean genotypes (PI207262 and BAC 6) and four accessions of snap-bean (UENF 1482, 1486 UENF, UENF 1487, UENF 1579). Twelve morphoagronomic traits of...

Environmental emissions profile of different sugar beet cropping systems in East of Iran

Iran is one of the main producers of sugar beet in the Middle East. Despite its great contribution to both local and global environmental impact, agricultural production systems in Iran is not very well investigated environmentally. This study characterizes some aspects of the environmental emissions inventory of sugar beet production in Iran, and compares the environmental performance of different cropping systems...

Screening of Pseudomonas fluorescens isolates for biological control of Macrophomina phaseolina root-rot of safflower

The aim of this study was to assess the potential bacterial antagonists to control Macrophomina phaseolinaroot-rot of safflower by using screening methods. In total, 38 fluorescent pseudomonads isolated from rhizosphere soil of healthy safflower plants were collected from major safflower growing areas, 13 were initially selected based on dual culture technique on potato dextrose agar media. Furthermore,...

Application of hyperspectral imaging sensor to differentiate between the moisture and reflectance of healthy and infected tobacco leaves

The main goal of this research was to develop the real-time remote sensing system as a rapid and field based method of identifying healthy and infected plants at an early stage of disease development, before visibly seen by human eye. This can be achieved through the use of hyper-spectral imaging collected data between 380 to 1030 nm wavelengths. The black-shank disease was inoculated to tobacco plants as a model system...

Growth and yield responses of cv. Merlot (Vitis vinifera L.) to early water stress

Reproductive growth is less sensitive to water deficit than vegetative growth. For this purpose, the main aim of this study is to find out the effects of early water deficits on vegetative and generative development of Merlot/SO4 grapevines. This research was carried out in ECOTRON System, Montpellier - SupAgro/INRA, 03°51’22’’ E and 43°37’04’’ N and 40 m altitude....

Evaluation of reduction approaches on frost damages of grapes grown in moderate cold climate

This study was done to investigate passive and active protective methods on reduction of losses from frost stresses in grapes cultivated in Shahrekord (Iran) during 2006 to 2008. Data analysis was done based on randomized block design, 3 replicates and five treatments including control without operate, Bordeaux mixture, increasing garden soil moisture up to field capacity, sprinkler irrigation upper grapes canopy,...

Quality of human capital for agricultural production in rural areas of Morogoro and Iringa regions, Tanzania

The quality of labour force is very important for agricultural productivity and attainment of food self sufficiency in Tanzania. This study was carried out to determine the nutritional status of rural agricultural workers in two selected villages in Tanzania, with the aim of assessing the quality of agricultural labour force. Adult household members from 117 randomly selected households in the two areas participated in...

Study of morphological traits changes in prolonged vegetative reproduction of three olive tree cultivars domesticated (Zard, Roughani and X) in Iran

Somaclonal variation of three Iranian olive cultivars namely Zard (Z), Roughani (R) and unknown cultivar Iks (X) during long-term propagation were evaluated among 5 subcultures. Morphological traits such as length and width of leaf, number of leaves on shoot, length of shoots, internode distance and rooting percentage were measured. Our results showed that R more than Z and X cultivars affected somaclonal variations...
