Garden pea yield and its quality indicators depending on the technological methods of growing in conditions of Vinnytsia region

Abstract

This paper aims to study the growth and development of garden pea plants when liming the soil, applying mineral fertilizers, pre-sowing seed treatment with inoculants, micronutrients and foliar nutrition. Plants survival was higher in the trial variant when applying lime (1.0 norm of lime per ha), mineral fertilizers, pre-sowing seed treatment with Rhizobophyte and microfertilizer Wuxal Extra CoMo, foliar nutrition with microfertilizers Wuxal Microplant at the microstage ВВСН 12–13 and Wuxal Calcium, Boron at the microstage ВВСН 51–59 – 92.0% and 92.1% in Skinado and Somerwood garden pea varieties. In the same variant, maximum values of the use of photosynthetic active radiation (PAR) were observed in Skinado variety – 1.38 and Somerwood variety – 1.89%. This was 0.47 and 0.57% higher compared to the control. The longest period of symbiosis, both general and active, was 35.3 and 37.1, 25.4 and 26.7 days. This was 2.2, 4.6, and 1.6 days more compared to the control where liming was applied. The highest rates of symbiotic and active potentials were observed in Skinado and Somerwood varieties and amounted to 14.0 and 15.4, 7.8 and 8.6 thousand kg per day/ha, and the amount of symbiotically fixed nitrogen (SNF) was 148.2 kg/ha in Skinado and 172 kg/ha in Somerwood variety. Pea yield was 9.36 t/ha in Skinado and 11.09 t/ha in Somerwood varieties. This was 2.15 and 2.14 t/ha more compared to the control. Green pea output was 46.4% in Skinado and 50.3% in Somerwood varieties. This was higher compared to the control by 4.4 and 3.0%, respectively.
