• Calculation of spacing and seed rate
A farmer had 1 hectare field to grow maize at the spacing of 90cm between rows and 45cm
between plants. Calculate the number of rows and plants. If each maize plant produced 2
cobs, and each cost P5.00 to sell, find income. If the farmer used 10 bags of fertiliser at a cost
of P205.00 each and the used 2 bags of P12.5kg seeds that were bought at P25.00 each,
calculate the profit.
