EVALUATING THE ROLE OF THE LIQUID ORGANIC FERTILIZER, OBTAINED FROM WORM COMPOST, ON THE PHYSIOLOGICAL DEVELOPMENT, QUALITY AND THE MAIZE HARVEST

The purpose of work consisted in the evaluation of the role of liquid organic fertilizer obtained from crude worm compost and drinking water in a ratio of 1: 100, on the process of emergence, physiological development and maize productivity. The experiment was conducted in the field conditions of Technological and Experimental Station "Maximovca". As a material for research was used a variety of maize M-450 and liquid organic fertilizer obtained from worm compost. In the experiment were included three lots: one control (with natural background) and two experimental: experimental I -maize seeds were macerated and fertilized, in three rounds, with liquid organic fertilizer (from considerations 4t/ha); experimental II -the seeds macerated in the same fertilizer without additional fertilization. It was found that macerating of seeds in extract obtained from crude worm compost and water and its administration as additional food, in triplicate, accelerated the emergence of maize, had improved physiological development and increased maize harvest with 18.26%. On the lot where were used only macerated seeds but not performed the supplementary feeding the maize harvest surpassed that of the control lot with 10.72%. So, it was found the beneficial influence of liquid organic fertilizer obtained from crude worm compost on the process of maize development.
