Question
Calculate the plant population of sugarcane in 1 ha
area, if planted in paired row spacing of 60/120 cm and the number of canes in 4-metre row length is 50.Solution
crop is sown in paired rows without maintaining plnat to plant spacing Intra pair spacing=60 cm Inter pair spacing= 120 cm Row spacing= 60+120/ 2= 90 cm Number of canes, N= 50, Row length, L=4 m (400 cm) Area, A= 1ha= 10,000m2 Spacing, R= 90cm  Plant population= (N×A×100×100) / (LR)  = 50×10,000×100×100/400×90= 1,38,888 plants.
