Particle film technology is a developing pest control system for tree fruit production systems. Trials were performed in Santiago, Chile, and York Springs, Pa., Wenatchee and Yakima, Wash., and Kearneysville, W. Va., to evaluate the effect of particle treatments on apple [Malus sylvestris (L.) Mill. var. domestica (Borkh) Manst.] leaf physiology, fruit yield, and fruit quality. Leaf carbon assimilation was increased and canopy temperatures were reduced by particle treatments in seven of the eight trials. Yield and/or fruit weight was increased by the particle treatments in seven of the eight trials. In Santiago and Kearneysville, a* values of the fruit surface were more positive in all trials although a* values were not increased in Wenatchee and Yakima. Results indicate that particle film technology is an effective tool in reducing heat stress in apple trees that may result in increased yield potential and quality.

There are no current commercial releases of genetically modified white clover, but several research groups are working on traits such as virus resistance, stress tolerance and bloat safety that are likely to provide large economic benefits for livestock farmers. However, white clover pollen is a common constituent of honey produced by bees foraging white clover flowers. Therefore, there is a need to develop tools to detect the presence of genetically modified pollen in white clover honey. The results presented in this paper describe the development and application of PCR-based techniques to detect the Alfalfa mosaic virus coat protein gene (AMV CP) and the neomycin phosphotransferase 2 selectable marker gene (npt2) in genetically modified white clover pollen, whether this pollen is collected fresh, from honey bees that have been foraging white clover, or from honey. Further research and development will be required to develop ‘field-ready’ tools for the detection and quantification of these transgenes in pollen and honey products. However, this paper demonstrates prospects and principles in pollen and honey from honeybees foraging transgenic white clover.

In our research, the adaptation of imported carniolan (Apis mellifera carnica Pollm) and Carpathian (Apis mellifera carpatica) honey bees to the natural climatic conditions of Uzbekistan, the main indicators of queen bees in experimental groups, the results of two-year assessment and economic benefits were studied for the first time in Uzbekistan.

Tomato is a popular and extensively cultivated vegetable among the promising commodities in horticultural production in Kenya. It provides a wide variety of nutrients with many health-related benefits. Despite the importance, its yield and net economic benefits is limited by the cultural practices applied by farmers. There is limited knowledge on the effect of integrating pruning and earthing up on tomato yield and net economic benefit. This study investigated the effect of integration of pruning and earthing up on the growth and yield of tomatoes. A split-plot experimental design, arranged in a Randomized Complete Block Design, with three replications was used. The study investigated two factors i.e. pruning system in the main plot (single stem, double stem, and triple stem) and earthing up in sub-plots. (0 cm, 10 cm, 20 cm, and 30 cm). Fruit yield data was taken after each harvest. Data were analysed using SAS version 9.4 and significant means were separated using the least significant difference at α = .05. The findings of the study revealed that earthing up and pruning system had a significant (p ˂ .05) effect on tomato yield and net economic benefit. Triple stem pruning system, earthing up to 30 cm had the highest fruit yield with 21.82 tonnes/hectare in cultivation 1 and 21.84 tonnes/hectare in cultivation 2. The findings also revealed that triple stem pruning system, earthing up to 30 cm had the highest net economic benefit per hectare in both cultivation 1 and cultivation 2. To improve tomato yield and consequently improve net economic benefit, farmers are encouraged to consider triple stem pruning system and earthing up to level 30 cm.

Apple orchard was planted in 1963 with treatments of 8, 6, or 4 m between rows and 8, 6, 5, 4, 3, and 2 m between trees in the row. Pruning of trees corresponded to the space requirement imposed by each treatment. Spherical canopy seldom formed in treatments of 8 × 2,3,4, or 5 m and the size of canopy was equal to the distance between trees. In treatment of row spacing 6 or 4 m the size of the canopy across the row was 3 or 2 m, respectively, with the length of the canopy equal to the distance between the trees. Tree height was 3 m in all treatments. The cultivar was `Antonovka' on Malus sylvestris rootstock. There were four replications. Fruiting in all treatments begun at the age of 8 years. During the 25 years of productive time of the orchard, there were 7 years without fruit. During the 33 years of orchard operations fruit yield was in treatments (in t·ha–1) 8 × 8 = 301, 8 × 4 = 417, 6 × 3 = 508, 4 × 3 = 612. Yield efficiency, based on crosssection of trunks in 1995 did not depend on orchard density or orchard design.
