Yield is decided long before harvest, and much of it is decided before the first seed goes into the ground. Rushing preparation once the rains arrive is how farmers end up planting late, into a rough seedbed, with whatever seed the shop had left. Working back four weeks from your expected planting date turns that scramble into a sequence of manageable jobs.
Week four: plan, test and budget
Start on paper. Decide what you will grow on which plot, taking rotation seriously so that you are not returning maize to maize or potatoes to the same ground year after year. Rotation breaks pest, disease and weed cycles more cheaply than any product you can buy.
Take soil samples now, because results take time to come back and any lime recommendation needs two to three months in the soil to act. Review last season honestly: which plots underperformed, where weeds got away from you, what you spent and what you actually earned. Then build a written input budget covering seed, fertilizer, crop protection, labour, land preparation and transport. Knowing the total in advance lets you prioritise if funds fall short, and the first things to protect in a tight budget are quality seed and adequate planting fertilizer.
This is also the week for clearing: remove crop residues and old debris that harbour pests, cut back field margins, and repair fences, terraces and drainage channels while the ground is still workable.
Week three: prepare the land
Carry out primary tillage, whether by tractor, ox plough or hand. The aim is to break compaction, bury weeds and open the soil so that the first rains soak in rather than run off. On sloping ground, work along the contour and check that your erosion control structures are intact, since a heavy first storm on freshly tilled slopes can remove a great deal of topsoil.
Apply lime now if your soil test called for it, spreading it evenly and incorporating it. Spread well-decomposed manure or compost at the same time and work it in, so it has time to integrate rather than sitting in clumps. Use only properly decomposed material; fresh manure burns roots and carries weed seed.
Week two: seed selection and the seedbed
Buy certified seed from a reputable supplier and keep the receipt and label. Certified seed costs more than grain from the store or last year’s harvest, but it delivers reliable germination, known varietal performance and freedom from seed-borne disease, and it is usually the highest-return decision in the whole budget.
Choose the maturity class that fits your rainfall and altitude rather than the highest-yielding variety on the shelf. A long-maturing variety that runs out of rain before grain fill will yield less than a medium variety that completes its cycle comfortably. Where your season is short or unreliable, earlier maturity is a form of insurance. Consider disease resistance relevant to your area, and check for treated seed, handling it with gloves and never feeding it to animals.
Work out your seed quantity from your plot area and the recommended spacing rather than by rough estimate, and add a small margin for gapping. Then complete secondary tillage to produce a fine, level seedbed with a good tilth, which is what gives you even germination and an even crop.
Week one: inputs, equipment and readiness
Collect your remaining inputs so nothing is outstanding when conditions turn right. Store fertilizer and seed in a dry place, raised off the floor, separate from chemicals and animal feed.
Service your equipment before you need it, not during the rush. Check the knapsack sprayer for leaks, clean or replace worn nozzles, and calibrate it so you know its real output per hectare. Sharpen and repair hand tools, check the plough and planter, and confirm your protective equipment is complete and in usable condition. Clean and dry your storage so that harvest, when it comes, has somewhere to go.
Arrange labour and machinery bookings now, since everyone in the district wants them in the same fortnight. Confirm who does what on planting day and make sure they understand the spacing and fertilizer placement you have chosen.
Plant with the rains, not the calendar
The last decision is the most important. Wait for genuine, established soil moisture rather than the first shower, checking that the soil is wet to planting depth and a little beyond. Planting into a false start means poor germination and often replanting at extra cost.
Once conditions are right, plant promptly and without delay, because early planting into a properly moist seedbed consistently outyields late planting. Place planting fertilizer in the furrow or hole and cover it lightly before the seed goes in, keeping granules off direct contact with the seed. Then note your planting date, variety and rates in a notebook. It costs nothing and it is what makes next season’s plan better than this one.
