Influence of Growth Regulators with Anti–Stress Activity on Productivity Parameters of Sinapis alba L.

Butenko Sergey, Melnyk Andrii, Melnyk Tetiana, Jia Peipei, Kolosok Volodymyr

Journal of Ecological Engineering

2022

Vol. 23, nr 9

128--135

The research results of using growth regulators with anti-stress action which stimulated growth and development of plants, and provided them with resistance to adverse factors during the vegetation period, were presented. The use of plant growth regulators with anti–stress effect on Sinapis alba L. increased the plant resistance to adverse environmental influences, providing adaptation to changing environmental conditions, i.e. it has a stress–correcting effect throughout the whole vegetation period. The result of using drugs on mustard (Sinapis alba L.) was obtaining a significant and stable additional seed yield (0.57 t·ha-1), i.e. an increase in yield by 38%. Over the years of research, the most effective were the applications of Fast Start and Biofoge growth regulators. The most effective processing terms were: during the vegetation period as well as combination of seed treatment and application during the vegetation period.

Performance of one potato plant as influenced by soil conditioner UGmax

Zarzecka K., Gugała M.

Journal of Ecological Engineering

Studies were carried out over the years 2008-2010 to determine the effect of Soil Conditioner UGmax on unit performance, that is potato tuber weight and number per one plant and average weight of one tuber. An experiment included two factors: I – two edible potato cultivars (Satina and Tajfun), II – five UGmax application methods (1. control without UGmax, 2. UGmax applied prior to tuber planting at the rate of 1.0 dm3 ha-1 , 3. UGmax applied prior to tuber planting at the rate of 0.5 dm3 ha-1 followed by two foliar applications at the rate of 0.25 dm3 ha-1, 4. UGmax applied prior to tuber planting at the rate of 1,0 dm3 ha-1 followed by two foliar applications at the rate of 0.5 dm3 ha-1, 5. two foliar applications of UGmax at the rate of 0.5 dm3 ha-1). Samples, consisting of tubers of 10 potato plants, were taken to determine the performance of one plant. The Soil Fertilise UGmax increased the weight of tubers per plant and the average weight of one tuber compared with the control. Moreover, the potato cultivars and weather conditions during the growing season significantly influenced the above-mentioned parameters.
