Effect of organic fertilizer and application of charcoal on quality of potato tuber variety atlantic

Abstract

The widely cultivated tuber in Indonesia is Granola. The Granola tuber is appropriate for table potato and not for processing one. The cultivation of potato cultivar Atlantic for processed potato should be increased. This research aimed to examine the quality of potato cultivar Atlantic with organic farming and compare their properties with a conventional system. Potato tuber cultivar Atlantic was cultivated with conventional and organic fertilizer. Fertilization was performed following the practices of the local farmers. Three types of charcoal produced from wood, husk, and coconut shell were applied at three different concentrations. The cultivation was conducted in the greenhouse located in the area of potato cultivation, at 1,300 m above sea level. Selected quality parameters of potato tuber regarding the processing and nutritional properties were determined: weight of yield, moisture and ash content and brightness of flour that produced from the tubers. The present study shows that organic fertilizer and charcoal application could contribute to the quality of potato tuber cultivar Atlantic. However, application of organic fertilizer and charcoal during cultivation does not increase significantly of tubers ‘properties. Further research for cultivation in the field is required to confirm this result.

Impact of Organic and Mineral Fertilizer on Some Physical and Mechanical Characteristics of Potato Tubers During Storage Period

“…The result was in agreement with the finding of Wibowo et al, (2021) they mentioned that the difference in tuber color is caused by differences in the carotene pigment content in each variety.…”

“…Regarding the rolling resistance of the tubers, it can be found that commonly for two varieties in the first two classes, this property was the highest and lowest on the galvanized iron sheet and the rubber and the wood surface, respectively. Wibowo et al, (2021), mentioned that the brightness level of Atlantic potato tuber flour produced was relatively high, ranged from 67.9 to 76.38. The higher the L-value means the brighter the color of the flour.…”

“…These lateral roots usually originate from the pericycle and grow through the cortex of the parent root. Once the lateral root breaks through the outer epidermal layer to the outside, pathogens create an entrance by the resulting crevice (Huang 1986;Gudesblat et al 2009;Meeteren and Aliniaeifard 2016;Vanhoutte et al 2016;Carvalho et al 2017;Silva et al 2018;Wibowo et al 2021). The space created by lateral-root formation is a representative avenue of entry for pathogens.…”
