“…A qualitative indicator of potatoes is the content or yield of dry matter (c/ha or t/ha). The composition of the dry substance includes approximately 80% starch [1][2][3][4]. Therefore, the yield of dry matter is an important criterion of starchiness.…”

“…Therefore, the yield of dry matter is an important criterion of starchiness. The establishment of dependencies between the chemical composition of soil, leaves, fertilizer doses and yield clearly indicates the possibility of practical use of these patterns for the diagnosis of mineral nutrition of plants [1][2][5][6][7][8].…”

The purpose of the research is to diagnose the mineral nutrition of potatoes based on the characteristics of the relationship between two variables. Potato yield in terms of yield increases to the control and background of mineral nutrition shows how effective doses of mineral fertilizers in double and triple combination are. The most effective option was nitrogen in a 2:1:1 combination at doses of N90P45K45 with an addition to the control of 1.47 t/ha (27.1%), and to the background of 1.28 t/ha (22.8%). In second place in terms of efficiency was the potassium variant in a 1:1:2 combination, where the increase was equal to the fertilizer-free variant of 1.45 t/ha (26.7%) and to the background of 0.98 t/ha (16.6%). Phosphorus fertilizers against the background of N45K45 gave an increase of 0.83 t/ha (14.1%), and in relation to the control – 1.29 t/ ha or 23.8%. Based on the statistical analysis of two variables "x" (fertilizer dose, kg/ha) and "Y" (yield, t/ha or c/ha), it is possible to show how much one indicator changes in relation to the other. Based on correlation and regression analysis, close relationships of two variables were obtained, which corresponded to high correlation coefficients r = 0.91 (nitrogen), r = 0.83 (phosphorus) and r = 0.93 (potassium).

In field experiments, the high energy efficiency of the use of mineral fertilizers for potatoes on chestnut soils of northern Kazakhstan was revealed. The energy efficiency of the use of nitrogen, phosphorus and potash fertilizers has been established. The energy consumption of nitrogen fertilizers per 1 kg of increase in the yield of the main product, depending on the doses of fertilizers, ranged from 6223,3 MJ (efficiency = 2,2 units) to 15129,6 MJ (efficiency = 1,0 units). The energy content of 1 kg of phosphorous fertilizers used by increasing the yield of potato tubers (c) was estimated from 11712 MJ (efficiency = 1,9 units) to 18300 MJ (efficiency = 2,5 units), which indicates high energy efficiency. Energy costs varied in the range of 5130,5 MJ against the background of N45K45 and 7208,3 MJ against the best variant of N45P90K45. The energy efficiency from the use of potash fertilizers is estimated at 2,2 units for variants K45 and K90 against the background of N45P45. Energy costs are reduced by obtaining 1 c of potato tubers in more efficient variants in terms of the energy efficiency of the fertilizers used. Knowing the energy costs (Ao, MJ) for growing crops and the energy content (Vf0, MJ/ha) in the yield of products, it is possible to conduct a bioenergetic assessment of the effectiveness of crop cultivation in the practice of applying fertilizers. The purpose of the research is to identify the bioenergetic efficiency of the use of mineral fertilizers for potatoes on chestnut soil in the conditions of the Northern region of Kazakhstan.
