“…The chemistry of K fertiliser had no effect on starch content in potato tubers of both cultivars (Table 3); this finding agrees with other findings from experiments with similar fertilisation (Westermann et al 1994;Sharma et al 2011), as well as with organic, biological and combined fertilisation (El-Sayed et al 2015).…”

Potato cultivars have different strategies for dealing with potassium (K) deficiency in soil, and their response to different forms and rates of K fertilisation may vary because of differences in soil K availability. This study was performed to evaluate the effect of K fertilisation rates (0, 30, 60, 90, 120 and 150 kg K/ha) on tuber yield and quality (dry matter, starch, sugar and ascorbic acid content, taste) of two potato cultivars (Roco and Rosara) grown in the microplot field experiment on Luvisol in the forest-steppe zone in southern West Siberia, Russia (NL 54.422106, EL 83.160257). The tuber yield of both potato cultivars increased with increase in K application rate up to 2.1 and 2.9 kg/m2 for Roco and Rosara, respectively. Sugar content, averaging 3.5%, was mostly determined by cultivar; however, in both cultivars it tended to decrease with increasing K application rate. The application of K fertiliser in the form of sulphate as compared to chloride increased dry matter content from 22.4 to 23.8% and ascorbic acid content from 13.2 to 14.6 mg/100 g fresh mass. Starch content of potato tubers averaged 59.7 ± 4.8% over all K fertilisation variants, with cultivar responses being different. Potassium application rate did not affect Roco tubers’ taste, while improving Rosara tubers’ taste under moderate application rates. The results underscore the importance to adjust fertiliser recommendations concerning potassium application rates and source on the basis of biological requirements and intended utilization of individual potato cultivars

“…29 Tuber Nitrate Increasing the nitrate accumulation in potato tubers has also been reported by other researchers. [30][31][32] It is believed that using high amounts of nitrogen-containing fertilizers in the soil, will result in increasing the absorption of nitrate by roots. This is while its reduction and assimilation does not increase in the same proportion, which results in nitrate accumulation in the plant's tissues.…”

Introduction: Nowadays, increasing environmental risks to human health have caused increasing attention to use chemical nitrogen sources efficiently or nitrogen supplying from organic amendments. In this respect, chicken manure seems to be a good alternative to chemical nitrogen fertilizers. The purpose of this experiment is to investigate the role of urea and poultry manure and ecological factors (climate) on the quantity of some chemical compositions of the potato tuber. Materials and Methods: To study the effects of urea and poultry manure on some potato tuber compositions, the factorial experiment was conducted in 2015-2016 during the growing season in 2 regions; Azna and Khorramabad which is located in Lorestan province in the west of Iran. The factors were 2 different sources of nitrogen supply including urea fertilizer and poultry manure. Results: Results show that the highest activity of nitrate reductase (NR) in both sites was observed using 10304 kg of poultry manure ha-1. The results also showed that the tuber nitrate content was only affected by the fertilizer source. In both studied places, the highest tuber nitrate was associated with high levels of urea fertilizer. Based on the results, the vitamin C of potato tubers grown by poultry manure were also superior to the relative vitamin C content. According to the results of this experiment, the accumulation of more than 2 times the nitrate in the tubers was obtained from urea fertilizer (244.2 versus 100 ppm). Conclusions: In order to achieve food security and an efficient and sustainable food chain, chemical fertilizers must be replaced with organic fertilizers. Thus, the belief that the use of organic fertilizers, at any level, would not cause any problem for the health of products is definitely incorrect.

This study was conducted to estimate whether natural K-feldspar fertilization alone and/or with silicate dissolving bacteria and banana compost as well as application with potassium could replace in full or partial with conventional potassium in sweet potato production with no converse effect on productivity. Thence, two field experiments were carried out during two successive summer seasons of 2013 and 2014 at the Hort. Res. Station of El-Bramoon, Dakahlia Governorate, to investigate the response of applied different sources from potassium fertilizers (potassium sulphate (PS) as conventional fertilizer and feldspar (FL) as natural potassium) at the recommended rate (96kg K 2 O/fed.) either single or in combination with others and/or the biofertilizer silicate dissolving bacteria (SDB); i.e. Bacillus circulans as well as banana compost on productivity and quality of sweet potato (Ipomoea batatas L.) cv. Beauregard. The obtained results indicate that the combined application of this treatment 25% kg K 2 O fed as + 25 %feldspar+25%banana compost+ SDB induced vegetative growth characters (vine Length, canopy dry weight and number of branches). Also, application of 25% kg K 2 O fed as + 25 %feldspar+25% banana compost+ SDB had the highest significant value among treatments in total yield,2marketable yield, tuber root characteristics (weight, length, diameter and dry matter %), chemical and organic composition (N, P, K, cured protein, total carbohydrates, total sugars and total carotenoids) of sweet potato plants. Therefore, it could be concluded that combined application of 25% kg K 2 O fed as + 25 %feldspar+25%banana compost+ SDB in sweet potato fields could be recommended to improve productivity and quality as well as utilization of the natural resources available in the Egyptian environment and minimizing the environmental impact of conventional potassium chemical fertilizers.
