Impact of growth biostimulators and herbicide on edible potato yield

Abstract

The aim of the study was to define the influence of cultivation methods involving the application of growth biostimulators and herbicide on the total yield of edible potato. The field research was conducted in 2015-2017 in the area of eastern Poland, in Lublin Voivodeship. The experiments were performed in three replicates using the randomised split-block method. The examined factors included: factor I -three early cultivars of edible potato (Owacja, Bellarosa, Vineta), factor II -cultivation methods involving the application of growth biostimulators and herbicide: GreenOK-Universal Pro and Asahi SL as well as their combination with the Avatar 293 ZC herbicide. The highest total yield of tubers was obtained from treatment 4, where prior to sprouting mechanical tillage was used, and after the final shaping of ridges and just before sprouting the Avatar 293 ZC herbicide was applied at a dose of 1.5 dm 3 ha -1 , and then after sprouting the GreenOK Universal-PRO was applied three times at doses: 0.10 dm 3 ha -1 -full moon-end of seeding + 0.15 dm 3 ha -1 -covering inter-rows + 0.15 dm 3 ha -1 -formation of flower buds (an average of 41.8 t ha -1 ), and from treatment 5, in which mechanical tillage was used prior to seeding, and after the ultimate formation of furrows before seeding of potato plants, Avatar herbicide 293 was applied in a dose of 1.5 dm 3 ha -1 (total yield amounted to, on average, 40.6 t ha -1 ). Potato cultivars cultivated in the experiment and meteorological conditions during the conducted tests also had a significant impact on the size of the total yield. Cultivar Owacja produced the highest yields (an average of 41.4 t ha -1 ). The largest total yield was collected in 2016 (an average of 42.8 t ha -1 ). A significant influence of the experimental factors on the structure of large tuber yields was also found. K e y w o r d s: potato, total yield, biostimulators, herbicide

Impact of growth biostimulators and herbicide on the yield structure of edible potato tubers (Solanum tuberosum L.)

“…The harvest of fractions with a diameter above 51 mm was classified to the harvest of large tubers. The results of research concerning total yield have been presented in the work of Baranowska (2018). The results of research on the impact of treatment methods on the harvest structure of potato tubers are based on average percentage values.…”

Elicitation as a Process of Enhancing Bioactive Compounds Concentration in Sprouts

“…Additionally, chlorine dioxide does not react with ammonium ions, so no chloramines are formed as a result of its presence [19]. Using aqueous solutions of chlorine dioxide for sprout treatment did not change the organoleptic properties of the product [20].…”

“…Since chlorine dioxide is commonly used to disinfect drinking water, its application as a plant elicitor, especially to sprouts, seems to be very attractive. Sprouts are one of the plant food products that have gained popularity in recent years and can be easily subjected to elicitation [20,[33][34][35]. These young plants provide essential nutrients and also biologically active compounds [36,37].…”

Effect of Bio-stimulants on Growth, Yield, Quality and Biotic Resistance in Chilli (Capsicum annuum L.)

“…Bio-stimulants increase plant growth and resistance to abioticstresses, improves performance of plant's vital processes hence favours higher yield and quality. In addition, bio-stimulants enhance nutrition efficiency or plant quality traits regardless of its nutrient contents apart from providing biotic resistance [6].…”
