If paddy is harvested using combine, then left over straw can be ploughed and mixed with soil, for this plough twice followed by planking. After this, use cultivator once and if soil is heavy plough it twice and apply planking each time. Use happy seeder machine to sow wheat in combine harvested paddy field without burning the left over of paddy.
(iii) Irrigation:
If wheat is sown in October then apply first irrigation after three weeks of sowing and then irrigate after four weeks. At this time, special roots are formed in wheat which are known as crown roots. 4-5 irrigations are needed for wheat.
(iv) Pest-insects and diseases:
Army worm, aphid, termite, gram pod borer etc. attack the crop. Diseases which can harm the crop are yellow rust, brown rust, loose smut, ear cockle (mamni) and yellow ear rot (tundu), and kamal bunt etc.

Question 1.
Write the sowing time and sowing methods of wheat.
Answer:
Optimum time for sowing wheat is from fourth week of October to fourth week of November. If sowing is delayed then the yield is reduced by 150 kg per acre per week.
Method of sowing:
Wheat is sown using seed-cum-fertilizer drill. Row spacing should be 20 to 22 cm and sowing should be done at a depth of 4-6 cm. Sowing should be done by using bi-directional method. This means use half seed and half fertilizer should be used in one direction and other halves on the other side at right angle to the 1st one. This will help in increasing the yield by 2 quintals per acre. Bed planter can be used to sow wheat on beds. In this method seed rate is 30 kg per acre and water requirement is also reduced.
Question 2.
Give methods of sowing of berseem.
Answer:
Suitable time of sowing for Berseem is last week of September to first week of October. Berseem is sown in standing water using broadcast method. If there is high wind, seed should be broadcasted in dry field and then use raking and irrigation.
Question 3.
Give importance of sulphur in oil seeds and name its sources.
Answer:
Usually, there is less need of sulphur for plants. But oil seed crops require more sulphur. In case of deficiency of sulphur yield is reduced. Use of sulphur is necessary for the use of nitrogen. For proper activity of enzymes and for synthesis of oil sulphur is necessary. Therefore superphosphate should be given in preference for phosphorus because it also contains sulphur. If this fertilizer is not available then use 50 kg gypsum per acre.
Question 4.
Name varieties of raya and give its nutrition requirement.
Answer:
Varieties: RLC-1, PBR-210, PBR-91.
Fertilizers:
40 kg nitrogen and 12 kg phosphorus per acre is required. Use potash after testing the soil. This is a oil seed crop and also require sulphur. Therefore use single super phosphate for phosphorus since it also contains sulphur. If this fertilizer is not available use 50 kg gypsum per acre.
Question 5.
Name broadleaf weeds of wheat and give their control measure.
Answer:
Broadleaf weeds which can infest in wheat are-Bathu, Button booti, Kandiali Palak, Maina, Maini, senji.
These weeds can be controlled by using 2, 4-D, Nomor, Algrip, Aim etc. Overdosing 2,4-D should be avoided if PBW 343 variety of wheat is sown. In case of broadleaf crops are sown in wheat then also avoid 2, 4-D.
