“…In the same tables, the interaction results indicated that the highest values of vegetative growth characters i.e., stem length, number of main stems/plant, number of leaves/plant, leaf area, foliage dry and fresh weights/plant, number of tubers/plant and tuber weight were significantly obtained by using potassium at 96 kg K 2 O/fed and spray with macro and micronutrients at 6g/L compared with the other interactions. Similar results were obtained by Ewais et al (2010) when used K-fertilizer as 50% of the recommended rate used as soil application + 50% of that added as foliar application. Moreover, Eleiwa et al (2012) found that the interaction between potassium levels and foliar nutritional compounds significantly affected number of leaves/plant.…”

“…Several attempts were done on the application of micronutrients spray to correct deficiency symptoms and enhance the vegetative growth of potato which in turn reflects on increasing yield and its quality for facing local consumption and exportation (Stashauskaite et al, 1979;Medvedv et al, 1981;Rashid et al, 1989 andTaya et al, 1994). Several investigators indicated that spraying plants with macronutrients enhanced plant growth, stimulated dry matter accumulation and increased yield and quality as well as chemical composition (Marchand et al, 1999;Roemheld and El-Fouly, 1999;Ewais et al, 2010;Habib et al, 2011;Eleiwa et al, 2012;Salim et al, 2014 andGhosh et al, 2017).…”

Two field trials were conducted on potato plants cv. Spunta, in vegetable private farm at Al-Enaniya village, Sinbelawin district, Dakahlia Governoraten, during 2014/2015 and 2015/2016 seasons to study the effect of soil application of potassium levels (96, 72 and 48 kg K 2 O/fed), either single and/or in combination with foliar spray of macro and micronutrients compound (N=25%, P=16%, K=12%, Zn=0.5%, Fe=0.5%, Mn=0.5%, Cu=0.3%) at different levels i.e., 6, 4 and 2 g/L on plant growth, yield and its components, as well as chemical constituents and storability of tubers. In general, results showed that potato plants fertilized with potassium sulfate at the level of 96 kg K 2 O/fed significantly increased plant stem length, number of leaves, leaf area and foliage plant fresh and dry weights as well as total yield, number of tubers/plant and tuber weight/plant, Moreover, this level of potassium significantly increased TSS, dry matter, specific gravity, Ascorbic acid (mg/g FW) and concentrations of macro and micronutrients (N, P, K, Fe, Zn, Mn, Cu). Also, potassium fertilization at of 96 kg K 2 O/fed had the most interesting observation which enhancing storability during storage period. Foliar spray with macro and micro nutrients at a rate of 6 g/L resulted in an increases in the most vegetative growth parameters, yield and tubers quality traits. However, weight loss percentage of tubers was significantly reduced during storage period.The combined treatments of potassium levels and foliar spray with some macro and micronutrients were generally more effective on the most studied parameters than single ones. The best results were obtained by application 96 kg K 2 O/fed with foliar spray of macro and micronutrients at the rate of 6 g/L. This treatment achieved increases in vegetative growth characters, total tubers yield (ton/fed), ascorbic acid (mg/g FW), TSS% of tuber, concentrations of N, P, K, micronutrients (Fe, Zn, Mn and Cu) in tubers and enhanced the tubers storability comparing with the other ones. Therefore, this treatment could be recommended for raising potato yield and improving tuber quality during storage period under similar conditions to this work.

“…Potassium (K) is well known for its importance for the growth and development of potato plants, and especially for tuber sensory quality as it is known to participate in starch biochemistry. Much research in various regions of Russia and other countries has been devoted to studying the effect of type, rates and forms of fertilisers on potato tuber yields and quality (Rhue et al 1986;Davenport & Bentley 2001;Ewais et al 2010). Most studies found that bigger yields correlated negatively with tuber quality, that mineral fertilisation should be carefully balanced, and that chloride-free fertilisers may be more beneficial.…”

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

This field experiment was coducted to evaluate the response of potato yield to foliar application of Grow More Nutrition. It was carried out in the vegetable research farm at the Department of Horticulture, Agriculture Collage, University of Karbala, Iraq during spring season 2015-2016. The treatments were three concentrations of Grow More Nutrition (T1 0 mg L-1 (control), T2 (25 mg L-1) and T3 (50 mg L-1) with three replication. The results showed that the application of T3 (50 mg L-1) had a sicnificant impact on number of tubers, tuber weight, yield per plant, total yield, net return and cost benefit ratio (8.67, 73.33, 0.64, 31.44 t ha-1, Din. 9408000 t.ha-1 And Din.3.969697 t ha-1, respectively.
