Question
List the steps of crop production in the correct order and briefly explain what happens at each stage.
(NCERT Class 8, Chapter 1 — Crop Production and Management)
Solution — Step by Step
We loosen the soil using a plough — this lets roots penetrate deep and allows air and water to reach the roots. Loosened soil also makes it easier for earthworms and microbes to do their work. This step is called tilling or ploughing.
Seeds are planted into the prepared soil at the correct depth and spacing. We use a seed drill for uniform spacing (better yield) or broadcast seeds by hand for smaller areas. Correct depth matters — too shallow and birds eat the seeds, too deep and the seedling can’t push through.
Crops need nutrients — mainly nitrogen (N), phosphorus (P), and potassium (K). We add manure (organic, from decomposed plant/animal waste) or fertilisers (chemical, like urea or DAP) to replenish what the crop will take from the soil. Manure also improves soil texture; fertilisers give a faster, more concentrated nutrient boost.
Crops need water at regular intervals. We supply this through canals, wells, tube-wells, or sprinklers when rainfall is insufficient. The frequency depends on the crop — paddy (rice) needs flooded fields, while wheat needs far less water.
Weeds compete with crops for sunlight, water, and nutrients. We remove them manually (by hand or khurpi) or use weedicides (like 2,4-D). If we skip this step, the weed can outgrow and choke the actual crop.
When the crop is mature, we cut it — manually with a sickle or mechanically with a combine harvester. The grain is then separated from the chaff through threshing (beating the stalks) and winnowing (using wind to separate lighter chaff from heavier grain).
Harvested grain must be protected from moisture, pests, and rodents. We dry the grain thoroughly first, then store it in silos, granaries, or gunny bags treated with pesticides. The Food Corporation of India (FCI) manages large-scale grain storage nationally.
Why This Works
Each step in this sequence solves a specific problem the plant faces at that stage of growth. Ploughing solves the soil compaction problem before the plant even exists. Sowing, manuring, and irrigation solve the nutrition and water problem during growth. Weeding removes competition. Harvesting and storage solve the preservation problem after growth.
Think of it as a chain — skip any one step and the yield drops or the stored grain spoils. That’s why NCERT calls this crop production and management, not just growing crops. Management is the key word.
For your Class 8 board exam, the sequence itself is a common 3-mark question. The NCERT sequence is: preparation of soil → sowing → adding manure and fertilisers → irrigation → protection from weeds → harvesting → storage.
Alternative Method
Some teachers present this as an acronym to memorise the sequence: PS-MIW-HS (Prepare Soil, Manure/fertilise, Irrigate, Weed, Harvest, Store). It’s clunky, but students who struggle with sequence questions find it helpful for exams.
For a 5-mark question asking you to “describe the steps”, write one sentence per step explaining what happens AND why — not just the name. CBSE board marking schemes award separate marks for the reason.
Common Mistake
Many students write threshing and winnowing as separate steps after harvesting, which bloats the answer and confuses the sequence. NCERT Class 8 groups them under harvesting. Only at Class 11 level do we treat post-harvest processing as distinct steps. For your Class 8 exam, keep threshing + winnowing under the harvesting step.
Another common error: students say manure and fertilisers are the same thing. They are not — manure is organic (slow release, improves soil structure), fertilisers are inorganic chemicals (fast release, no structural benefit). Examiners specifically test this distinction.
The final answer for a fill-in or sequence question: Preparation of soil → Sowing → Adding manure and fertilisers → Irrigation → Protection from weeds → Harvesting → Storage.
