Potato growers of Jalandhar region plan to install grading machines of international standard to cut cost and increase accuracy of grading of the crop. The growers have approached Holland-based company Allround Nu-Tech for the purpose, Jalandhar Potato Growers Association general secretary Jaswinder Singh Sangha said on Tuesday. "At present, potatoes are graded by hand on the field. The grading machines will not only cut cost, which is Rs 1 per kg, but also ensure accurate grading,' he said after attending a demonstration of the machine by the company. The machine is capable of grading 10 tonne of potatoes in a hour and it costs Rs 16 lakh, he said, adding that the company has ensured subsidy of Rs four lakh from Agriculture Processed Food Export Development Authority (APEDA). As grading machines are movable, the same could be taken right into the fields to get maximum use and a farmer could save at least Rs 2 lakh per season by installing the machine in his field, he added. SC Malik, managing director of Allround Nu-Tech's Ambala division said the company manufactures grading machines for all agriculture products and India has a huge scope of marketing.
