Rezumat

During the period 2012-2013, a study was made on the effect of using deep-water organic-mineral sediments (sapropels) of the Black Sea as amendment for alluvial meadow soil (Calcaric Fluvisol) – manure substrate used for seedlings production of eggplant cv. Patladjan 12. The results obtained after two years of field experiments showed that the introduction of 30 g/kg of Black Sea sapropels increases the pH of soil-manure substrate from 7.42 to 7.74 units and improves the growing parameters of eggplant seedlings as follows: the height of the central stem by 9.20%, the width of the central stem by 0.98% and the number of leaves by 8.15%. According to the field experiment, the early standard yield of eggplant fruits increased by 14% for the plants grown in Variant I and the total standard yield - by 10.6% compared with the control variant

În timpul perioadei 2012-2013 a fost efectuat un studiu cu privire la efectul utilizării sedimentelor organice-minerale de adâncimi mari (sapropelul) din Marea Neagră ca amendament pentru substratul sol aluvionar de luncă-gunoi de grajd utilizat la producerea răsadului de vinete cv. Patladjan 12. Rezultatele obţinute după doi ani de experimente de teren au arătat că introducerea a 30 g/kg de sapropel din Marea Neagră măreşte pH-ul substratului de sol-gunoi de grajd de la 7,42 la 7,74 unităţi şi îmbunătăţeşte parametrii de creştere a răsadului de vinete precum urmează: înălţimea tijei centrale cu 9,20%, lăţimea tijei centrale cu 0,98%, iar numărul de frunze cu 8,15%. Potrivit experimentului de teren, randamentul standard timpuriu de vinete (fructe) a crescut cu 14% în cazul plantelor cultivate în varianta I, iar randamentul standard total – cu 10,6%, comparativ cu varianta martor.
