ЭФФЕКТИВНОСТЬ ПРИМЕНЕНИЯ ОРГАНОМИНЕРАЛЬНЫХ УДОБРЕНИЙ И МИКРОБИОЛОГИЧЕСКИХ КОНЦЕНТРАТОВ В ВЕГЕТАЦИОННЫХ ОПЫТАХ С ТОМАТОМ И ПЕРЦЕМ

Microbiological concentrates Azoto and phosphate Barvar of Iranian production according to certificate activate azotfixation from the atmosphere and transform complex phosphoric minerals of the soil to forms accessible to the plants. They are introduced into the soil in the form of water solution. In vegetation experiments of row crops the yield of tomato variety Lia in variants with mineral and organic fertilizers (semi-rotten manure, granulatedbird droppings and organomix, ORWACO) according to 3 years’ average data made 475-519, that of the pepper variety Nush 477-500, and in the consentrates of both crops 453 d/pot. In the control variant it was 432 and 418 g/pot, respectively. The content of nitrates in the ripe fruits in all variants of tomato exceeded the MPC (150 mg/kg in open soil) but in the fruits of pepper it was 4 times lower than MPC (200 mg/kg in open soil) which is probably connected with varietal peculiarities. The vegetative mass of the studied crops in the variant of microbiological concentrates has also been the smallest. [ABSTRACT FROM AUTHOR]
