Planting Time Effects of Top-Shoot Cutting on Yield and Grade for Rapid Seed Potato Multiplication ()
ABSTRACT
Top-shoot cuttings were evaluated as planting material with different
planting time for rapid multiplication of potato. Plants produced from
top-shoot cuttings planted on 25th November (T3) produced
higher mean tuber yield (32.95 tha﹣1) than December planting. Total
yield of potato increased 122.8% from early one source crop plants due to taking two times cutting and it was 89.7 % from
late one source crop plants. Seed tuber yield increased 167.89% and 95.33% in
early and late one source crop plants, respectively. The highest gross net
return of Tk. 984,440 was found from whole tuber planted on 10th November with benefit cost ratio of 3.42. From top shoot cuttings, the highest
net return of Tk. 739,600 was found in T3 (25th November
planting) with benefit cost ratio of 6.20. The crop grown from early planted
top-shoot cuttings also produced higher percentage of A and B grade seed tubers
than late planting. The results revealed that top shoot cuttings would be used
in potato production for getting maximum economic return.
