SULEYMENOVA, N., I. RAIYMBEKOVA and D. PETKOVA, 2012. Ecological aspects of resourcesaving technology of soybean. Bulg. J. Agric. Sci., 18: 227-232

The elements of a resource-saving technology of soybean growing, providing higher yield and ecologicaleconomic efficiency, were studied. New science-based elements of a resource-saving technology of growing were applied and replacement of soybean after better predecessors, minimizing soil cultivation, increasing the yield (up to 29.8 – 32.3 kg.ha^-1) and profitability (up to 60.6 – 83.5 g.kg^-1).

Key words: soybean, resource-saving technology, herbicide, weeds, damage criterion of harmfulness, productivity
Abbreviations: q - quintal, ha - hectare, l – litre, m – meter, mm - millimeter, cm – centimeter, pcs. – pieces, THE - Threshold of Economic Harmfulness, AET - Appropriate Economic Threshold, HTC –hydrothermal coefficient
