Productivitatea hibrizilor de porumb și ritmul pierderii apei din boabe la recoltare în condițiile climatice ale Zonei de Nord a Republicii Moldova
2024
Bucur, Nicolae
The article presents a synthesis of investigations conducted on 10 corn hybrids from the early and medium maturity groups, tested under ecological conditions in the northern part of the Republic of Moldova in 2023 at the Visoca Testing Station in Soroca District. According to tests carried, the productivity of the corn hybrids varies on average between 8,17 and 8,61 t/ha, depending on the maturity group. This variation underscores the influence of ecological factors on the development of the hybrids. Corn hybrids from the medium maturity group demonstrate a productivity that is 0,44 t/ha higher than that of the early maturity group. The year 2023 provided favorable climatic conditions for assessing the water loss capacity of the kernels, from physiological maturity to harvest. The maximum intensity of moisture loss from the kernels was observed in the stage IV, where the average percentage of moisture lost per day was 0,45% for hybrids from the early maturity group and 0,48% for those from the medium maturity group. Thus, hybrids with different capacities for moisture loss from the kernels were obtained. The tests highlighted corn hybrids with varying rates of moisture loss from the kernels even after harvest, particularly emphasizing those from the medium maturity group.
