იაპონიიდან ინტროდუცირებული მანდარინის ადრემწიფად ჯიშ „ნიჩინანზე“ აგრობიოლოგიური ფაქტორების გავლენა ზრდა-განვითარებასა და მოსავლიანობაზე

In the Black Sea subtropical zone, the reservs to assimilate the new areas for the citriculture has been exhausted and further development of the sector is mainly possible with the introduction of modern technologies, while increasing the cost of the plant should be carried out by replacing biologically amortized plants by arranging sedimentation nurseries, raising soil fertility, timely conduct of agro-techniques and plant pest control measures and correctly organizational-practical issues.
Since our region belongs to the Extremely northern subtropical zone, it is necessary to select varieties that are suitable for our zones, which are distinguished by early ripening and high yield.
In 2018 - 2019 with the initiative of the ministry of Agriculture of Adjara for solution of this problem, tangerine Nichinani were imported from Japan, which was planted in the Kobuleti municipality. The plants are planted with nutritional air of 4-2.5 meters, at 35-40 meters above the sea level, the soil is red. We have ten plants that we have studied: - the formation of buds, the beginning and end of vegetation, the massive flowering, setting, the beginning of the ripening of the fruit and the full ripening, high yielding (piece, kg) the average weight of one fruit (g.), the color of the fruit, the nature of the skin removal from the flesh, number of seals in flesh and organoleptic characteristics. We received fruit from different expositions of the plant and explored biochemical indicators at the University Laboratory. (Tanaka T. 1958; R. Jabnidze 2018).
The novelty of the research is that we have examined the first phonological, agroecological and agro-tecnological characteristics of eleven varieties of introductive tangerims, from which only three varieties: Nichinani, Iura-Vase, Taguchi – Vase identified the best characteristics for our zone and were recommended to be a super early sorts, which are 40-45 days prior to the localin breeding. We recommend the cultivation of such plants by growing citrus areas and therefore productivity. The novelty of the research is also that the intensive technological complex also includes organizational and economic measures and economic issues that will be directed to improve organizational management and management of the sector.
