EFFECTS OF MINERAL AND ORGANIC FE RTILIZATION ON EARLY POTATO PRODUCTION
I. Mitova, N. Dinev, V. Vassileva
Abstract: The objective of the study was to establish the influence of organic, mineral and organic-mineral fertilization on the growth, development, yield and some quality indicators for early potatoes. A field experiment in crop rotation with early potatoes of the sort Agata was staged on alluvial-meadow soil in 2011-2012. The scenario included a regime without fertilizer, a regime with mineral fertilizer, organic fertilizer (manure) and mixed organic and mineral fertilizer. The highest yield in the conducted experiment (32.42 t.ha-1) was obtained under the mixed fertilization regime. The plants under the regime with organic fertilizer showed lower biometric indicators as compared to those fertilized with mineral or organic-mineral fertilizers. As regards quality indicators, the biggest tubers (101.42 g/tuber) were obtained under the mixed fertilization regime with high content of total sugars - 5.1% and low content of nitrates - 49.79 mg.kg-1.
