Question

Maximum yield of maize attained with a population of 50000 plants per hectare. The rows are 150 cm apart and on average emergence of 85% is expected. How many seeds per hill should be planted if hills are 150 cm apart?

(a) 13

(b) 15

(c) 17

(d) 19

I got this question in an online quiz.

The above asked question is from Sowing Equipments in chapter Sowing Equipments of Farm Machinery

Answer 1

Right choice is (a) 13

To explain I would say: Number of seeds per hectare = \(\frac{50000}{0.85}\) = 58823

Area covered per hill = 150 * 150 = 22500 cm^2 = 2.25 m^2

Number of hill per hectares = \(\frac{10000}{2.25}\) = 4444

Number of seed per hill = \(\frac{58823}{4444}\) = 13.
