dc.description.abstractThe present investigation entitled “Storage studies in potato (Solanum tuberosum L.) under ambient conditions” was carried out in Post-harvest Laboratory of the Department of Vegetable Sciences, CCS Haryana Agricultural University, Hisar during the year 2012. The three grades of potato tubers, i,e,, small, medium and large, of variety Kufri Badshah, Kufri Bahar, Kufri Pukhraj and Kufri Pushkar were packed in gunny bags in all the possible combinations under ambient conditions. The storage experiment was started on 9th March 2012 and ended on 9th June 2012. The observations were recorded on physiological loss in weight (%), decay loss on number and weight basis (%), sprout loss on number and weight basis (%), total loss (%), dry matter (%), specific gravity (%), starch content (%), nonreducing sugar (mg/100g), reducing sugars (mg/100 g), total sugars (mg/100 g), ascorbic acid (mg/100 g), phenol content (mg/100 g), black or hollow heart and general appearance of the tubers. The loss in weight of tubers due to physiological activities, decaying and sprouting increased with the increase in storage period and the loss was more in larger than smaller and medium tubers. Sprouting was 100% in Kufri Bahar with all possible combinations during storage. Dry matter content and specific gravity also increased with increasing storage period and both were more in larger tubers. There was a marked reduction in phenol, ascorbic acid and starch content of potato tubers during storage up to the end of the experiment. Phenol had the negative correlation, whereas, starch and ascorbic acid content had the positive correlation with the size of potato tubers. Reducing and total sugars decreased up to 45th day of storage, but thereafter, both increased up to the end of storage and were negatively correlated with size of the potato tubers, however, non-reducing sugar showed the reverse trend. Black or hollow heart was absent completely in all the possible treatments. So far general appearance of the tubers was concerned, the larger tubers shrivelled more and earlier than the medium and small sized tubers.en_US
