Explanation

(a) Cultivation of maize
(i) Soil requirements

  • Well drained soil, rich in nutrients;
  • Sandy-loam soil;
  • Thrives on neutral or alkaline soil

                                                                                        
(ii)  Method of propagation   

  • Propagated by seed.

                                                                                     

(iii) Spacing

  • 90cm x 30cm at one seed per hole/stand;
  • 75cm x 25 cm at two seeds per hole/stand.

 

(iv)  Weed control

  • Done manually with cutlass and hoe;
  • Done 2-3 times on the farm at regular intervals;
  • Could also be done mechanically with implements pulled by animals;
  • Herbicides could also be used.

 

(v) Two fungal diseases

  • Corn smut;
  • Maize rust;
  • Leaf spot

 

(vi)  Harvesting

  • On  a low/small scale, could be harvested manually by breaking the ear from the maize plant;
  • Cutlass could be used to slash the whole plant while the ear is broken from the plant;
  • Combine harvester could be used on a large scale when the moisture content of the crop is low (25-28%);
  • Could be harvested green or dry;
  • Crop is due for harvesting from 60-120 days after planting depending on variety.

(b) Description of farm records           
(i) Production record 

  • Shows the yield of crops cultivated on the farm;
  • Shows the produce from livestock/farm animals;
  • Shows the date of collection of farm produce;
  • Helps to forecast yield.

 

(ii)  Farm inventory

  • Farm inventory is a record of all the assets on a farm at a particular time;
  • These include buildings, feed, land, animals, produce in storage and the number of machines on the farm;
  • Usually taken at the beginning and end of the year;
  • Shows the value of the assets on a farm;
  • Shows the state of each equipment.

                                                                                        
(iii)  Cash book

  • The cash book shows the financial transactions of the farm;
  • These include receipts from goods bought, salary of workers, cost of inputs and output, records of all payment made to the farm;
  • Shows receipts/sales on the left hand side;
  • Shows expenses/payments on the right hand side;
  • Shows date of transactions.

                                                                                                                      
(iv) Labour record

  • Shows the number of hours that they work and dates;
  • Shows particular problems with workers;
  • Shows number of casual or permanent workers and their qualifications;
  • Shows the wages/salaries of workers on the farm;
  • Shows the performance of workers.
