guilan province is the biggest hazelnut producer in iran. over 70% of hazelnut production cost is due to its manual harvesting. therefore, study on all aspects of its cultivation mechanization is necessary to sustain its production. this study focused on identifying factors that affect the development of hazelnut harvesting mechanization in guilan province, iran, using a three-round delphi tech...

Crop yield estimation is an important task in apple orchard management. The current manual sampling-based yield estimation is time-consuming, labor-intensive and inaccurate. To deal with this challenge, we developed a computer vision-based system for automated, rapid and accurate yield estimation. The system uses a two-camera stereo rig for image acquisition. It works at nighttime with controll...

Prolonged exposure to organophosphates in low concentrations caused diarrhoea in 38 students, lecturers and other personnel at an agricultural college. The symptoms of those affected, plasma pseudocholinesterase levels, topography of the orchards and vegetable gardens, the various insecticides and quantities used, and the exposure due to prevailing winds have been studied. We conclude that safe...

Microbacterium sp. strain Yaish 1 is a rhizospheric bacterium isolated from date palm orchards with high soil salinity. The genome was sequenced, and genes coding for growth-promoting 1-aminocyclopropane-1-carboxylate (ACC) deaminase, siderophore-producing proteins, and tryptophan biosynthesis proteins were identified. Here, we report the draft whole-genome sequencing of the strain.

In Uzbekistan, the areas of intensive orchards are expanding, in which branches regularly pruned according to agrotechnical rules. orchards, number fruit trees is usually greater, so cut occupy most row-spacing area. They interfere with many operations, they must be removed. Usually, this work done manually. True, some rakes collect and take them out field. The parameters existing do not always...

Wild olive seed weevil, Anchonocranus oleae Marshall, larvae as well oviposition and feeding damage were recorded in cultivated olives during a recent study on wasps. Prematurely dropped fruit picked at harvest two orchards near Stellenbosch Agter-Paarl examined regularly for wasp infestation over three seasons. In addition, collected the growing regions of Western Cape province survey to deter...

The application of a microencapsulated (MEC) sex pheromone formulation (Checkmate CM-F) for codling moth, Cydia pomonella (L.), in low volume, concentrated sprays was evaluated in a series of small plot and grower trials in apple, Malus domestica Borkhausen, and pear, Pyrus communis L. Preliminary tests found that MEC sprays applied at 172-207 kilopascals in 12-23 liters/ha deposited the highes...

Plant ionomes and soil nutrients are commonly diagnosed in agronomy using concentration and nutrient ratio ranges. However, both diagnoses are biased by redundancy of information, subcompositional incoherence and non-normal distribution inherent to compositional data, potentially leading to conflicting results and wrong inferences. Our objective was to present an unbiased statistical approach o...

Regulation of agricultural pests managing their natural enemies represents an alternative to chemical pesticides. We assessed the potential of insectivorous birds as pest regulators in woody crops located in central Spain. A total of 417 nest boxes installed in five field study sites (one vineyard, two fruit orchards, and two olive groves) were monitored for use and breeding of insectivorous bi...
