Study Notes
Wheat
- Triticum species (genus) are commonly cultivated in India
- Hard wheat originates from Abyssinia, Soft/Bread wheat from North-West India, South-West Afghanistan and USSR
- Wheat is a temperate crop, sown in the rabi season
- Sowing time varies based on variety: Tall varieties are sown from last week of October to first week of November
- Wheat is used for making bread, chapatis, cakes, biscuits, pastries, and other bakery products.
- Wheat straw is used as fodder and for thatching and mulching
- Wheat can be grown on a wide range of soils, but prefers well-drained soils with good water holding capacity
- Wheat grows well on light to heavy clay soils
- The genus Triticum can be grown from light to heavy soils
- It requires well-drained soils due to its temperate nature
Paddy
- Swarming Caterpillar: the pest is found in large groups that eat young plants
- Control measures: Burning grass and wild rice, and applying thimet granules are recommended
- Paddy Gall Fly: affects paddy plants by damaging the leaves and stems
- Control measures: It is recommended to apply 10% Thimet granules at the rate of 10 kg per ha. after 10 and 20 days of transplanting
- Rice Bug: it sucks juice from developing grains, usually during the milk stage
- Paddy Blast: symptoms include spindle-shaped brown to reddish brown spots appearing on the leaves. The spots on stem and grains are darker
- Paddy Blast Control measures: Grow resistant varieties, treat the seed with perenox, cupravit, or Cuprosan
- Foot Rot/Stem Rot: symptoms include small irregular black spots appearing on the leaf sheath, the resulting damage can cause stunted growth and failure to tiller
- Foot Rot/Stem Rot control measures: grow resistant varieties, treat the seed with perenox, cupravit, or Cuprosan
Gram
- Also known as Harbhara, Chana, Bengal gram, Chick pea
- Botanical name: Cicer arietinum
- Family: Leguminosae
- Origin: South-West Asia
- Gram is considered a fertility restorative crop
- Gram grows best in well-drained, light to heavy black, mixed red, or alluvial soils
- Sandy loam to clay loam soils are most suitable
- The optimum pH range for gram is 6 to 7.5
- The best climate for gram is cool and dry with low to moderate rainfall (400-700 mm)
- The average temperature required is 25 to 30 degrees Celcius
- Excessive rainfall after sowing or at flowering can cause great harm
- Cloudy weather and frost conditions during flowering can reduce flowering and seed setting
- Gram is fairly hardy and can be grown on rough or cloded seed beds
- The cultivation of gram requires one deep ploughing after Kharif harvest by iron plough
