IMPACT OF CERTAIN AGRO-TECHNICAL FACTORS ON THE GRAIN YIELD OF TRITICALE, VARIETY ROZHEN

Dimitrinka Krusheva

Abstract


The study was carried out in the experimental field of the Scientific Center for Agriculture – town of Sredets in the period 2011-2013, on leached cinnamon forest soil, preceding species was coriander, using the block method, in four repetitions, with the size of the experimental plot 25 m2. The particular object of the study is triticale crop, Rozhen variety. The following factors were scrutinized in the study: three seed rates: 450 germinatable seeds / m2; 560 germinatable seeds / m2; 700 germinatable seeds / m2, three sowing periods: 1-5 October; 15-20 October; 1-5 November and four levels of nitrogen fertilization: N0; N6; N10; N14.

The goal of the conducted research was to unveil the complex interaction of factors (sowing time, seed rate, fertilization rate) in growing triticale crop, Rozhen variety, at the specific conditions of Strandzha Mountain and the impact of such factors on the ultimate grain output.

Our research revealed that in the conditions of the studied region, triticale crop, Rozhen variety achieves the highest yields when sowing is in the period 15-20 October, seed rate is 560 germinatable seeds / m2 and fertilization is with N14 kg/da.
