Chapter List
Chapter 1: Cultivation of Rabi and Kharif Crops
This chapter covers Pakistan’s two seasonal crop groups: Rabi (winter) crops like wheat, gram, barley and mustard, and Kharif (summer) crops like cotton, maize, rice and sugarcane. It explains the three soil textures (sandy, clayey, and loamy), traditional land-measurement units, land preparation methods, and seed germination testing. Detailed cultivation guides follow for wheat, gram, cotton, rice, maize and sugarcane, covering soil choice, sowing time, fertilizer schedules, irrigation timing and expected yield per acre.
Important Questions:
- What is the difference between Rabi and Kharif crops? Rabi crops are sown in early winter and harvested by summer (wheat, gram, barley), while Kharif crops are sown at the start of the monsoon and harvested by autumn (cotton, rice, maize).
- What are the three types of soil by texture, and which is best for cultivation? Sandy, clayey, and loamy soil; loamy soil is considered best because it retains the nutrients and moisture plants need.
- What is karund and how does it harm crops? A hard crust that forms on the soil surface after rain following sowing, blocking air from reaching the roots and stunting growth; it is broken up with a tool called karundi.
- What is the recommended sowing and harvesting time for wheat, and its typical yield? Sown mid-November to mid-December, harvested April to May, giving an average yield of 40 to 60 maunds per acre.
Chapter 2: Protection of Plants and Animals
This chapter teaches how to recognize healthy versus diseased plants and describes major crop diseases and their control, including wheat rust, loose smut, sugarcane borers, cotton root rot, and rice blast, plus harmful insects and spray safety precautions. The second half covers livestock: common cattle, buffalo and poultry breeds, signs of a sick animal, major animal diseases with symptoms, common veterinary medicines, and proper shed hygiene.
Important Questions:
- How can healthy plants be recognized? They look fresh and vigorous, are free of spots and blemishes, stand firmly rooted, and show natural coloring in stems, leaves, flowers and fruit.
- What benefits does fencing a field provide? It protects crops from strong winds and storms and prevents animals from entering and damaging the field.
- What precautions should be taken while spraying pesticide? Spray at the recommended time, avoid foggy or overcast weather, cover hands, face, nose and mouth, and use only the medicine recommended for that crop.
- What are the signs of a sick animal? It stops eating normally while thirst increases, stops chewing cud, shows a change in body temperature and coat color, and breathing becomes fast or labored.
Chapter 3: Restoring Soil Fertility
This chapter explains what makes soil fertile, a balanced mix of clay, silt and sand, organic matter, and adequate nitrogen, phosphorus and potassium, and describes a pot experiment showing how nutrient deficiency stunts plant growth. It covers two categories of fertilizer, organic (farmyard and green manure) and chemical (urea, ammonium sulphate, DAP), along with safe application practices, crop rotation, and using gypsum to reclaim saline land.
Important Questions:
- What characteristics define fertile soil? Adequate potassium, calcium and magnesium, a balanced mix of clay, silt and sand, enough looseness for air circulation, and sufficient organic matter to hold moisture.
- What are the two main categories of fertilizer? Natural/organic fertilizers (farmyard and green manure) and chemical fertilizers (urea, ammonium sulphate, superphosphate).
- What is crop rotation and why is it useful? Growing a small leguminous crop after a major crop instead of repeating the same crop; this restores nitrogen and fertility to the soil and helps control weeds.
- How is gypsum used to reclaim saline (thur) land? Mixed into the soil or applied via irrigation water, its calcium replaces sodium, forming sodium sulphate that drains below the root zone, restoring fertility.
Chapter 4: Protection of Agricultural Land
This chapter covers land conservation: measuring soil moisture, testing soil pH and phosphorus, controlling erosion on sloped land through tree planting and bunding, and maintaining organic matter through crop rotation and manure. It explains waterlogging and its remedies (drainage channels, tubewells), and salinity and its reclamation through gypsum and salt-tolerant crops, closing with a survey of farm implements like the harrow, leveler and seed drill.
Important Questions:
- What does agricultural land protection mean? Measures that prevent farmland from losing its natural fertile composition, including checking soil moisture, managing water flow, and treating waterlogging.
- What is seem (waterlogging) and how is it treated? It occurs when the underground water table rises close to the surface, cutting off air to roots; treated with drainage channels, proper irrigation, and tubewells.
- What causes soil erosion on sloped land, and how is it prevented? Strong winds, heavy rain and floods wash away topsoil; prevented by planting trees and bunds, keeping fields under crop cover, and building check-dams.
- What is thur (saline-alkaline soil) and how is it reclaimed? Land where excess salts accumulate on the surface; reclaimed by applying gypsum, flushing water through the soil, or growing salt-tolerant crops.
Chapter 5: Protection and Better Use of Water Resources
This chapter covers the protection and efficient use of water resources in farming, noting that plants are 75-90 percent water by weight. It surveys water sources such as tube wells, canals, rainfall, springs, karez channels and wells, then explains conditions for efficient irrigation, including the khal-kiyari division method that saves about 10 percent of water, along with pucca channels, field bunding, and furrow and flood irrigation techniques.
Important Questions:
- Why is a large piece of land divided into small plots for cultivation? Dividing land into small plots, as in the khal-kiyari method, lets water spread evenly and saves about 10 percent of irrigation water.
- What are the main water resources described in the chapter? Canals, tube wells, rainfall, springs, artesian wells, karez, ponds, wells and the dhenkli.
- What factors cause irrigation water to be wasted in field channels? Poor cleaning and maintenance, uneven channels, high or low channel beds, weak banks, and weed growth.
- How can irrigation water be conserved on the farm? By building pucca (lined) channels, leveling fields, bunding plots, clearing weeds, and using the khal-kiyari or sprinkler methods.
Chapter 6: Mushroom Cultivation
This chapter introduces mushroom (khumbi) cultivation, highlighting its nutritional value of 40 to 47 percent protein, higher than meat or milk, with very low starch and fat making it suitable for heart and diabetes patients. It describes four types grown in Pakistan and two cultivation methods, bedding paddy straw under tree shade or growing in thatched rooms with controlled humidity, and explains harvesting after two to three weeks.
Important Questions:
- What is the nutritional importance of mushroom? It contains 40 to 47 percent protein, more than meat or milk, with very little starch and fat, making it good for heart and diabetes patients.
- Name the main types of mushroom grown in Pakistan. Chinese (paddy-straw) mushroom, Dhingri mushroom, chestnut mushroom, and European mushroom.
- How is mushroom cultivated under tree shade or in open orchards? Beds are prepared from layers of paddy straw with mushroom spawn placed between layers; sprouts appear within 10 to 15 days.
- When and how is mushroom harvested? Cut two to three weeks after spawning once it reaches proper size, using a sharp knife, taking care not to leave cut pieces on the bed.
Chapter 7: Storage and Protection of Agricultural Produce
This chapter covers storage and protection of harvested produce, noting pest and disease damage costs Pakistan roughly 200 crore rupees annually. It profiles major storage pests like the wheat weevil and khapra beetle, rat-control methods, pre-storage precautions such as drying grain to safe moisture levels, storage methods from jute bags to cement silos, and godown fumigation with phosphine and other gases.
Important Questions:
- Name some pests that damage stored agricultural produce. The wheat weevil, khapra beetle, saw-toothed grain beetle, flour beetle, pulse beetle and rats.
- What precautions should be taken before storing grain in a godown? Inspect and repair the godown in advance, seal cracks, ensure ventilation, and sun-dry grain to bring moisture to 10-12 percent.
- What methods are used to clean a godown of insects? Heating the room to kill insects, or fumigating with gases such as phosphine, methyl bromide or EDCT after sealing doors and windows.
- What precautions must be observed while using insecticides in storage? Use only when pest damage exceeds a tolerable limit, spray with the wind, avoid eating or smoking nearby, and apply under experienced supervision with protective gloves.
