    Olive cultivation is a traditional symbol of the Mediterranean climate zone. It is important to harvest the olive fruit at the appropriate time and to collect the whole product without damaging the trees during this harvest. Damage of fruits during harvesting directly affects the product quality and thus the producer’s earnings. There are three main technologies commonly used in olive harvesting. The first of these; It is a hook type olive harvesting machine that performs the harvesting process by giving vibration to tree branches. Secondly; combs type are harvesting machines that vibrate given directly to the fruits and also the leaves and thin branches. The third is the trunk shaker type olive harvesting machines which take action from the tractor and vibrate to the trunk of the tree. In this study, some olive harvesting machines used in Turkey are compared in terms of performance and efficiency. Within the scope of the study, both domestic production and imported technologies are included. As a result, it has been found that the shaker type olive harvesters have a higher performance as expected. In contrast, the cost of this technology is higher than other olive harvesting technologies. Comb type olive harvest technologies are left behind in terms of performance compared to other harvest technologies. However, the costs of these machines are much cheaper than other olive harvesting technologies. On the other hand, it causes more damage to fruits and leaves.

    On the basis of an integrated wheel-type tractor (traction class 3.0), there was created the new combined machine and tractor unit carried out a continuous flat cutting of the sugar beet tops with a front mounted sugar beet tops cutting machine. To carry out this field experimental studies, a program and methodology was developed based on measurements of the remains of the tops on the heads of root crops after passing through the aggregate at a given rate of translational motion, the height of the installation of its rotary cutting mechanism above the level of the soil surface and the frequency of its rotation. The results of the study were statistically processed on a personal computer using regression and correlation analysis methods. Based on the developed methodology of the full-factor experiment, empirical mathematical models were constructed in the form of regression equations for the process of cutting the tops of sugar beet. According to the results of these calculations, it was found that the speed of the forward movement of the sugar beet tops cutting aggregate exerts the greatest influence on the mass of the remains of the tops on the spherical surfaces of the root heads, after a continuous main cut. In a lesser extent, this process is influenced by the rotational speed of the rotor of the sugar beet tops cutting machine and the height of the rotor installation above the soil surface level by means of two pneumatic copying wheels. According to the results of experimental studies, it has been established that the rational design and technological parameters of the process for harvesting sugar beet tops by a front mounted sugar beet tops harvesting  machine with a rotary cutting apparatus is its rotation frequency equal to 960 rpm, the speed of the aggregate should not exceed 2.0 m.s-1, and the height of the rotor installation should be as low as possible, not less than 0.02 m.

    Irrigated agriculture is the largest water consuming industry in agricultural sector of Kazakhstan consuming up to 70% of the total water resources consumed by all sectors of the economy. One of the methods for increasing the irrigation water efficiency is the construction of technically advanced irrigation systems, allowing use of water-saving irrigation technology: drip irrigation, enabling to save irrigation water by 20-30% and increase the productivity by 2.0-2.7 times.

    This article outlines promising methods to improve the performance and quality of grain combines by harvesting only ears as part of the harvest. The various types of earstripping machines, which are investigated in Kazakhstan. Also remaining standing straw is a good means of accumulating moisture on the soil and resistance to wind erosion.

    The cultivation of short rotation coppice (SRC) such as poplar and willow on agricultural land is of increasing interest for farmers. But high investment costs, high processing costs, low flexibility of the machines as well as high machine weights are problems, which hinder an extensive implementation. Therefore, the development of a simple and low weight mower-chipper was started. The chipper was designed for mounting in front of medium sized standard tractors. The new developed machine has been tested in three harvest periods.

    Because of the very promising test results an industrial production is in preparation. To analyse the storage behaviour of wood chips different outdoor storage experiments were carried out at practice scale. Storage of coarse wood chips from the mower-chipper was compared with storage of fine chips produced by a forage harvester. Only small differences were found between both chip sizes.

    Oil rose production is a traditional branch in the economy of the Republic of Bulgaria and in production of rose oil the country is a world leader more than a century.

    In the article the evolution and state of equipment used in oil rose growing are analyzed, the problems in the mechanization of technological operations are identified and the proposals are made for a mechanization of the only one fully rely on manual labor activity – the harvesting of rose petals.
