THE YIELD OF CICER ARIETINUM DEPENDING ON INTENSIFICATION ELEMENTS OF CULTIVATION TECHNOLOGY

Presented here are the research results on the effectiveness of applying plant protection products in the technology of chickpea growing. It was revealed that the cicer arietinum had a low productivity (1.28 t/ha) on sowings where plant protection products were not applied due to significant growth of weeds and infections of cicer arietinum plants. It was discovered that the cicer arietinum productivity grew up to 2.30 t/ha, or by 1.02 t/ha, when the soil herbicide Reiser KE (2.5 l/ha) was used. When the herbicide was applied, the productivity almost doubled, while using the Fastak, K.E. (alpha-cypermethrin, 100 g/l) in a concentration of 0.15 l/ha had no effect on productivity. In case of the three-step application scheme of fungicides such as Rex Duo, SC (epoxiconazole, 187 g/l + thiophanate-methyl, 310 g/l) in a concentration of 0.5 l/ha at the early phase of budding, Abacus (pyraclostrobin, 62.5 g/l + epoxiconazole, 62.5 g/l) in a concentration of 1.5 l/ha during flowering, and Folikur 250 EW, WB (tebuconazole, 250 g/l) in a concentration of 1.0 l/ha during seed filling, the productivity increased by 0.90 t/ha compared to the variant where fungicides were not applied. In total, due to the use of plant protection products in the experiment, the productivity increased from 1.28 t/ha to 3.21 t/ha, i.e. by 1.93 t/ha (150.8 %). The highest increase (1.02 t/ha) occurred when the herbicide Reiser KE immediately after sowing. The three-step use of fungicides also led to significant growth of productivity (by 0.90 t/ha). Based on results of the economic effectiveness of chickpea growing the net profit from 1 ha increases by 27.848 hrivnya, namely from 11.446 hrivnya on the variant without using plant protection products to 39.294 hrivnya on the variant on which the herbicide Reiser KE was used and fungicides were applied in three steps. The level of profitability was the lowest (77.1 %) on the variant with no pesticides and it increased to 212.6 % on the variant on which herbicides and fungicides were applied
