“…Increasing chlorophyll contents by enhancing enzyme activity with adequate amount of soil K that reflect on potato growth and definitive conversion in to sink (tubers) (Nazli et al, 2018), translocate assimilates and synthesis of protein, this also reflexed on leaves chemical composition (as shown in Tables 5 and 6) that increased tuber yield (as shown in Table 7) and its quality (as shown in tables 8 and 9). These results are in harmony to those obtained by Salim et al (2014); Zelelew et al (2016); Abou zeid and Abd El-Latif (2017) and Agrawal et al (2017) on potato.…”

Potato is considered strategic vegetable crop in the entire world. So, two field experiments were conducted in the experimental farm, Faculty of Agriculture, Mansoura University to study the effect of organic fertilization and foliar application with potassium (K) as well as rates of K soil fertilization and their interaction on vegetative growth (plant height, No of leaves/plant, fresh and dry weight), leaves chemical composition (Chlorophyll a, b, a+b, N, P and K), tuber yield (plant yield, No. of tuber/plant and total tuber yield) and its quality (TSS, reducing, non reducing, total sugar, vitamin C, starch and protein). The experiment was conducted in strip split plot design including 12 treatments i.e. 2 organic applications (compost and vermicompost), 2 foliar applications (tap water as a control and K at 2%) and three rates of K soil applications (120, 165 and 214 kg K 2 O/hectare). The obtained results clarified that using compost and foliar application with K at 2% as well 165 kg K 2 O/ha significantly increased leaves chemical contents and tuber quality, while using vermicompost and foliar application with K at 2% plus 165 kg K 2 O/ha gave the highest values of potato growth parameters and yield. Thus, it can be recommended that using compost or vermicompost at 9.5 and 7 ton/ ha and foliar application with K at 2% as well 165 kg K 2 O/ha that gave the highest net return and improve quality of potato tubers.

“…Vermicompost had a great effect on increasing specific gravity of potato tubers. With the increasing of Vermicompost levels were shown maximum specific gravity in tuber (Agrawal et al, 2017).…”

“…Sprouting is a physiological process at which resting buds break their dormancy and resume growth by utilizing stored food (Salisbury and Ross 1992). Dry matter content increased with the increasing of Vermicompost levels (Kmeťová et al, 2013;Agrawal et al, 2017). A positive correlation (r=0.751) was found between the dry matter content and specific gravity of potato tuber (Fig.…”

The effect of vermicompost on dry matter and specific gravity of potato tubers under ambient storage condition was studied. Vermicompost was used at four rates viz. 0, 2, 4 and 6 t ha-1 over the four varieties of potato viz. BARI TPS-1, BARI Alu-28 (Lady Rosetta), BARI Alu-25 (Asterix) and BARI Alu-29 (Courage). Results demonstrated that processing parameters such as dry matter percentage (%) and specific gravity increased with increasing vermicompost levels while they decreased with the increasing storing period. Lady Rosetta and Asterix potato varieties can be safely stored at normal room temperature up to 60 days. There was no interaction between vermicompost rates and crop varieties. Hence, the potato growers of Bangladesh can use vermicompost at 6 t ha-1 for achieving better yield without affecting processing quality. SAARC J. Agri., 17(2): 173-184 (2019)

“…During ambient storage condition; specific gravity of potato tuber decreased with increasing ambient storage time, however higher level of vermicompost and bigger tuber size exhibited gradually decreased of specific gravity compared to control with sharply decreased of specific gravity [41].

“…High dry matter content is an important processing quality factor, however during storage condition, it reduces gradually. High dry matter content (%) was observed which might be due to the application of high rate of vermicompost which played an important role in affecting the dry matter of tubers [38,39,40,41]. Loss of dry matter of tuber during storage period may be due to respiration [42].…”
