What crop management practises are
40 min · 1 practice tasks · quizAfter establishment, Grade 7 manages a crop by thinning, gapping, physical weeding and earthing-up.
-
Spacing and plant population
40 min · 1 practice tasks · quizA measured spacing sets how many plants belong on a bed; extra plants will be thinned and missing ones gapped.
-
Thinning crowded seedlings
40 min · 1 practice tasks · quizThinning removes extra seedlings so the remaining plants have the planned spacing, light and water.
-
Gapping empty spaces
40 min · 1 practice tasks · quizGapping replants missing plants with the same crop while the stand is still young so the bed keeps its population.
-
Why weeds harm the crop
40 min · 1 practice tasks · quizWeeds steal water, light and nutrients, hide pests and dirty the harvest; they must be removed while they are still small.
-
Physical weeding safely
40 min · 1 practice tasks · quizCarry out weeding by hand, hoe or mulch, with space between workers and the blade down when you talk.
-
Earthing-up selected crops
40 min · 1 practice tasks · quizEarthing-up draws soil to the base of crops such as potato and maize to cover tubers, support stems and hold moisture.
