FIELD GERMINATION AND SURVIVAL OF CHICKPEA PLANTS DEPENDING ON TECHNOLOGICAL METHODS OF CULTIVATION
Abstract
Common chickpea (Cicer arietinum L.) is a promising legume crop, capable of providing stable yields under conditions of moisture deficiency, which is especially relevant in the context of modern climate change and the increase in the frequency of dry periods. At the same time, the formation of productive chickpea crops largely depends on the density of plant stands, field germination of seeds and the level of plant survival during the growing season, which are determined by both varietal characteristics and applied technological methods of cultivation. The aim of the research was to assess the effect of pre-sowing seed inoculation with the bacterial preparation Bioinoculant- BTU-r in combination with foliar top dressing with microfertilizer Help Rost (Bor) on the formation of stand density, field germination and survival of chickpea plants of the Triumf and Pamyat varieties in the Right-Bank Forest- Steppe of Ukraine. Field studies were conducted during 2023–2025 under different hydrothermal conditions of the years. The assessment of the condition of the crops was carried out in the key phases of organogenesis according to the BBCH scale. As a result of the research, it was found that the sowing dates in different years practically did not affect the timing of emergence, while intensive technological methods ensured stable and friendly seed germination. Pre-sowing seed inoculation contributed to an increase in field germination to 86.65–87.33% and had a positive effect on the initial crop density. The complex application of inoculation and two-time foliar feeding ensured the highest plant survival during the growing season and an increase in the density of the stand before harvesting by 4–5% compared to the control. The survival rate of chickpea plants under these conditions increased on average to 11.43%.
The results obtained confirm the feasibility of using biological preparations based on nodule bacteria in combination with microfertilizers containing boron as an effective element of resource-saving technologies for growing chickpeas in order to increase plant adaptability, stability of agrocenoses and efficiency of crop production.
