THE EFFECT OF THE POLYCOMPOSITE COMPOST ON THE NUTRITION AND PRODUCTIVITY OF SUN-FLOWER
Abstract
The effect of a polycomposite compost consisting of three organic waste (farmyard manure, sewage sludge, and marine algae) on the nutrition and seed production of the sunflower cultivated in a field experience on a Chernozems in the southeastern part of Romania, was investigated for 2 years. Three types of compost were made from different mixtures of the three components added in proportions by 25% or 50% so that each compost was prevalent in one of them. Agro-chemical analyses of soil samples (pH and N-NO3, N-NH4, PAL, KAL content) collected towards the end of the sun-flower growing season, have demonstrated very good plant nutrition conditions, and even an oversupply of nutrients brought by the compost, as compared to unfertilized control. Also, the content of macronutrients (N, P, K, Ca, Mg) and metallic microelements (Zn, Cu, Fe, Mn) in the leaves under the calathidia, harvested during the seed formation, recorded normal values, and in some cases (N, K, Ca, Zn, Cu, Fe) even higher values. As a result, the seed production was, on average, up to 1.9 times higher than those recorded in the unfertilized control experimental variant. The largest sun-flower seed crop, by 4.28 t/ha, was obtained in the experimental variant fertilized with the compost consisting of 50% marine algae, 25% farmyard manure, and 25% sewage sludge, applied to the soil in a dose of 100t/ha.
