Performance of One Potato Plant as Influenced by Soil Conditioner Ugmax

Abstract

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 dm 3 ha -1 , 3. UGmax applied prior to tuber planting at the rate of 0.5 dm 3 ha -1 followed by two foliar applications at the rate of 0.25 dm 3 ha -1 , 4. UGmax applied prior to tuber planting at the rate of 1,0 dm 3 ha -1 followed by two foliar applications at the rate of 0.5 dm 3 ha -1 , 5. two foliar applications of UGmax at the rate of 0.5 dm 3 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 abovementioned parameters.

Influence of Edible Potato Production Technologies with the Use of Soil Conditioner on the Nutritional Value of Tubers

“…The positive effect of using biostimulants on the starch content of potato tubers has been reported by many authors [10,39,74]. Such an effect is due to the microorganisms contained in the soil conditioner [52][53][54]. On the other hand, a study by Maciejewski et al [75] showed no effect of biostimulant application on the starch content of potatoes, which may be due to the application of biostimulants only in foliar form.…”

“…After the inoculation of soil and plants with soil conditioner, regardless of the factors studied, a significant increase in dry matter content was found, on average by 4.3 and 1.4% for Experiment I and II, respectively, compared to facilities where UGmax was not applied (Tables 1 and 2). The use of a soil conditioner in potato production reduces tuber infestation by pathogens, which contributes to improving the quality of the tubers in terms of nutrients [52][53][54].…”

“…A positive correlation was also found between the soil conditioner and manure, as a significant increase in dry matter content of 8.5% was obtained in Experiment 1 (Table 1). This is due to the better utilization of soil minerals after the application of soil biostimulants, which accelerate the decomposition of organic material [54]. In addition, Kazimierczak et al [5] note the positive effect of the organic farming system on the increase in dry matter content in tubers.…”

Changes in Carbohydrate Contents in Table Potato Tubers Under the Influence of Soil Conditioner Ugmax

“…UGmax -double foliar application (10-15 cm potato plant height) at a dose 0.5 dm 3 •ha -1 , (flowering) and at a dose 0.5 dm 3 •ha -1 . The conditioner contained: lactic acid bacteria, photosynthetic bacteria, Azotobacter, Pseudomonas, yeast, actinomycetes as well as the following amounts (mg l) of macroelements and microelements: potassium − 2905, nitrogen − 1200, sulphur − 1000, phosphorus − 220, sodium − 200, magnesium − 100, zinc − 20, manganese − 0.3produced by Bogdan, Trade-Service Co., Poland (Trawczyński, 2007;Zarzecka and Gugała, 2013). Farmyard manure was applied at a rate of 25.0 t ha -1 in addition to mineral fertilisers used at the following rates: 44.0 kg ha -1 P (in the form of 46% triple superphosphate -Group Azoty Chemical Establishments Police SA, Poland), 124.5 kg ha -1 K (in the form of 60% potassium salt -Establishments Trading Commodities Siarkopol Sp.…”
