EVALUATION OF THE TECHNOLOGY OF CULTIVATION OF CORN HYBRIDS IN THE CLIMATIC CONDITIONS SPECIFIC TO THE TIMIS PLAIN
Abstract
The main objective of the theme taken in study is to bring a contribution to the development of an intensive technology for corn, in conditions of good favorability. The area under study is part of the Timis Plain and is characterized by climatic conditions conducive to corn cultivation, being framed in the very favorable cultivation area in our country. In order to highlight the behavior of the corn hybrids taken in the study, determinations were made regarding: grain production, depending on the hybrid (kg ha-1); mass of 1000 grains (g) and hectoliter mass (kg/hl). In 2023, the harvest was significantly higher than in 2022, but also much more variable. The t-test indicates a statistically significant difference between the means, suggesting that factors influencing the harvest had a major impact. This large variation in 2023 may be influenced by external factors such as climatic conditions, agricultural technologies, fertilization or crop management. In detail, the TKW values in the two years of the experiment vary between 273 g (for the P 9889 hybrid) and 285 g (for the P 0217 hybrid). The average TKW for all four hybrids is 278g. The highest HW values were recorded in the P9978 hybrid and the P0217 hybrid, reaching 60 kg/hl. As a result of this study we can affirm that the application of an appropriate technology for the corn crop must combine: a balanced fertilization, depending on the expected result (quantity, quality, diseases and pests resistance) and a valuable genotype, these in the context of constantly changing climatic conditions.
