Abstract
The high efficiency of vegetable crops is influenced, in addition to soil preparation works, weed, diseases and pests control, irrigation, etc. by precision sowing, which involves placing a certain number of seeds at an exact depth and distance. Thus, cost savings, a high reliability of production and especially a greater uniformity of crops are achieved, most often uniform and quality productions being obtained. For vegetable species in the case of which harvesting is practiced only once, uniformity of seed distribution is particularly important. In most cases, vegetable seeds have small size, irregular shape and small mass. These characteristics make the development of precision seeders for this type of seed quite difficult. Precision sowing of vegetable seeds ensures a correct sowing rate, which implies an optimal space for plant growth and development, thus improving crop yields. The paper presents a summary of the current state of precision seeders equipped with electrically operated distributors for vegetable seeds, as well as the preliminary results of research conducted by authors in this field.

Summary
Precision agriculture aims to optimize agricultural production and environmental quality, being defined as a complex system that applies advanced technologies combined with agricultural management practices and crop-specific information, taking into account aspects of their temporal and spatial variability [1, 2, 3, 4, 5]. The placement of the correct amount of seeds per unit area, respecting the prescribed sowing depth, together with achieving uniformity of distance between seeds on the row and between rows, significantly influences the yield. The correct sowing norm ensures a better germination and an optimal space for plant development, with weed suppression effects [13, 14]. Numerous research units and companies producing agricultural machines have dealt with the study and development of electrically operated distribution devices, intended for precision sowing. The research and results presented in the paper are a premise for optimizing precision seeders for vegetable seeds
