Evaluate of tomato growing in the conditions of subirrigation aeroponics at Fitopiramida greenhouse

Abstract

Aeroponics and hydroponics technologies are one of the most advanced today. The aim of this work is to select and assess the assortment of determinant tomatoes for suitability for cultivation under the conditions of this technology. The study was conducted on the crop of two specific hybrids of different foliar dressings, as well as the assessment of the level of interaction «variety-option of feeding» based on the statistical analysis of the results. The article discusses the features of two methods of the aeroponics and Fitopyramida soilless technology in the context of solving the problems of resource and energy conservation in the production of vegetables. It is applied in agriculture to plan the several activities and missions properly by utilizing limited resources with minor human interference. The aim of this work is to evaluate the effectiveness of non-root top dressing and to identify the optimal habitus and other characteristics of the determinant tomato hybrid for the “Fitopiramida” technology. A greenhouse research project was conducted at All-Russian Scientific Research Institute of Vegetable Growing - a branch of the Federal State Budgetary Scientific Institution “Federal Scientific Center of Vegetable Growing” (VNIIO - a branch of FGBNU FNTSO). This study was revealed that 2 foliar dressing at a dose (N: P: K 10:54:10) 2.5 g/l + Maxifol 2g/l ) have a significant impact on productivity and yield determinant hybrids of tomato Flame F1 and Rosana F1, providing yield increase in comparison with the control by 7.87 kg/m2 and 2.52 kg/m2, respectively. Among the investigated options for the use of mineral fertilizers, the most maximum and reliable results were obtained in the 3NPK option; on the basis of statistical processing, the optimal variant of the interaction «variety-level of mineral nutrition» was established - hybrid F1 Rozanna against the background of 3NPK.
