(а) 15 October to 15 November

Time of sowing for barley is 15 October to 15 November. Spacing for normal sowing should be 22.5 cm and for rainfed and late-sown crop spacing should be 18-20 cm. It can be sown like wheat without ploughing i. e. without any preparatory tillage.

For rain fed crop time of sowing is 10 to 25 October and for irrigated conditions crop, time of sowing is 25 October to 10 November. Seed rate is 15-18 kg per acre.

40 kg per acre

Saline, alkaline or waterlogged soils are not suitable for lentil.

10 to 25 October.

Yield is reduced by 150 kg per acre per week.

Last week of September to first week of October.

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.

Correct answer is 40-43%.

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.

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.

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.

Canary grass (gullidanda), Senji (sweet clover), Maina (toothed bur clover), Maini.

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.
