Abstract
Two field experiments were conducted during t he t wo successive wi nter s easons of 2006 and 2007 at t he experimental statio n of t he Agriculture Research Center (A RC), Kafr El-Zayat, El-Gharbia Governorate, E gypt t o study the response of p otato plant ( Solanum tuberosum L.) cv. Valor t o m ineral and bio-potassium fertilizers and its effect on the growth, yield and quality of tubers. T he exp eriment included 16 treatments representing the interaction of four mineral-K fertilizer treatments (45, 90, 135 and 2 180 kg K O /fed.) w ith four b io-potassium fertilizer tre atments (c ontrol, 2, 3 and 4 L. /fed.).(Fed. = 0.4 ha.). Results showed that increasing of potassium s ulphate l evels as mineral potassium f ertilizer increased the veget ative growth characters of potato plants, i.e., plant length, leaf number/plant, a nd leaf area/plant as well as fresh a nd dry weight of whole pl ant. Application of potassein as a bi o-potassium f ertilizer improved plant growth characters compared with untreated plants. Using of potassein at the lev el o f 3 L./fed. gave the highest values of vegetative growth characters. Moreover, increasing of mineral potassium 2 fertilizer up t o 180 kg K O /fed were gradually increased the potato tubers yield. Likewise, tubers number/plant an d marketable tubers percentage as w ell as tub ers quality e xpressed as sp ecific gravity, starch %, protein % and dry matter % showed positive res ponses to increasing m ineral-K levels, and the 2 highest values with t he hi ghest level of mineral-k (18 0 kg K O /fed.). While, the l owest values were 2 recorded with the lowest lev el (4 5 kg K O /fed.) in both se asons. In teraction between mineral an d bio-K fertilizers had a positive effect on the productivity of potato p lants. The highest value of yield w as recorded with potato plants which received potassein a s bio-K fertilizer at the level (3 L. /fed.) combined 2 with pot assium s ulphate a s mineral-K fertilizer at the level (90 kg K O /fed.) in bot h s easons. Likewise, tubers quality a nd N, P contents in the tubers showed the same trend of t he yield of p otato plants in both 2 seasons. W hile, K content i n the tubers was in creased with the highest m ineral-K level (1 80 kg K O /fed.) a long with the highest b io-K level (4 L. / fed.) in both se asons.
