Potato, nitrogen, potash, processing qualities for chips and yield. |
| Abstract: |
Field and storage experiments were conducted to find out the main effects and interactions between
different levels of nitrogen and potassium fertilizers on total yield, yield of different size grade,
storability and better processing quality for chips of potato variety Kufri Jyoti at Hattiban farm
Khumaltar and storage house of Nationai Potato Research Program (NPRP) Khumaltar and at
Balaju cold store, respectively. After harvesting and curing of potato, 5 kg of tubers weight each
tuber more than 60 gram weight were used for the storage and processing qualitY determination.
The storage experiments were conducted in CRD design with 3 replications. Plastic racks and net
bags were used for storage of potato in dark room and cold storage house, respectively. Potato was
stored for 90 days in dark room and 120 days in cold house. Laboratory analyses were carried out
at National Academy of Science and Technology (NAS1) at Lalitpur before and after storage of
potato in ordinary conditions and before immediately after removing from cold store and 15 days
after re-conditioned. Observations were recorded on yield, storage losses, sprouting, chips quality
parameters like specific gravity (SG), dry matter (DM) and reducing sugar (RS). The storage loss
and sprouting percentage was recorded at 15 days intervals of dark sore potatoes and before
storage, immediately after removing from cold and 15 days after reconditioned of cold store
potatoes. The results showed a significant effoct of N and K20 and there interaction on yield,
sprouting, weight loss percentage and quality parameters. Based on the yield and quality
parameters the combination of 150:100:60 kg N: P20 5: K20 along with 20 tons compost I ha is
found suitable for storage and production of processing chips quality potato at Lalitpur and
similar soil and environment condition of Nepal. |
