The effects of production factors on the yield and quality of millet (Panicum miliaceum L.)

Millet is considered as a plant of extremely good adapatability, which makes the late and second sowing of the crop possible. However, the effects of late sowing can be observed in the efficiency of production technological elements. This research was carried out in a small-plot field experiment set in the Nyíregyháza Research Institute of the UD FAFSEM in 2013, in four replications. Among the production technological factors (sowing date, nutrient supply, cultivation area), the greatest effect was observed in the case of sowing date. Under non-optimal conditions caused by late sowing, the impact of production technological elements are of significantly lower extent. Between a1 and a2 sowing dates (12. 06., 25. 06.), the decrease of yield was low, 181 kg ha-1, while in the case of the a3 sowing date (03. 07.), yield decrease was significant compared to the first two sowing dates. The most favourable yield was obtained in the case of the 36 cm row spacing, which may be related to the sowing date. The protein content was more favourable in the case of the later sowing date (03. 07.); although in this case yield significantly decreased. The effects of the studied factors were similar in terms of protein content and extraction rate; although the extremely late sowing resulted in the obvious increase of protein content.
