20 may to 5 june is the optimum time for sowing For normal sown crop a spacing of 20 - 22.5 cm between rows is recommended. When sowing is delayed a closer spacing of 15-18 cm should be adopted. Broadcasting method The seedlings should be transplanted at 2 to 3 cm depth. Shallow planting gives better yields. Before sowing, soak them in 10 Ltr water containing, Carbendazim@20gm+ Streptocycline@1gm for 8 to 10 hour before sowing. After then dry seeds in shade. And then use for sowing. 15th to 30th May is the optimum time for nursery preparation. It is done in region having adequate water availability. Nursery area is about 1/10 of the area to be transplanted. Broadcast Pre-germinated seeds on puddled and levelled soil. Keep the beds moist for the first few days. Do not flood the beds. When the seedlings are about 2 cm high, keep the beds submerged in a shallow layer of water. Apply dose of 26 kg/acre Urea about a fortnight after sowing. For transplantation use seedlings of 15-21 days or when seedlings are 25-30 cm long. Regularly irrigated the nursery. It is prepared in dry soil condition. Total seed bed area is about 1/10 of the area to be transplanted. Make seed bed of convenient dimensions with the soil raised at height of 6-10 cm. Spread half burned rice husk on these beds for easy uprooting. Irrigation should be done properly because less moisture can damage seedling. Incorporate basal fertilizer for proper nutrients. This is the modified method of nursery making which require less space and less quantity of seeds. It can be cultivated at any place having flat surface and assured water supply. The area needed is about 1% of the transplantable land. Establishing seedlings in 4 cm layer of soil mix, arranged on a firm surface. Make 1 meter wide and 20-30 meter long plot and spread plastic sheet or banana leaves on it. Place a wooden frame with 4 cm deep and then fill the frame with soil mixture. Sow pre-germinated seed in it and cover the seed with dry soil. Immediately sprinkle water on it. Irrigate frame as and when needed and keep it moist. Seedlings are ready for transplanting within 11 to 14 days of sowing. Transport seedling mat to field and separate them and transplant 1-2 seedlings at 20x20 cm or 25x25 cm spacing. The seedlings should be transplanted at 2 to 3 cm depth. Shallow planting gives better yields. Transplant seedlings in line at 20x15 cm for normal and 15x15 cm for late transplanting. Put 2 seedlings per hill and the seedlings should be transplanted upright and about 2-3 cm deep. Transplant seedlings on middle of slopes of bed. These bed are prepared by wheat bed planter in heavy soil. Before transplanting irrigate the furrows, then transplant seedlings by maintaining a plant to plant distance of 9 cm. For transplanting Mat type nursery, mechanical transplanter are used. It transplant seedlings at spacing of 30x12 cm.

For paddy apply N:P:K@50:12:12 kg/acre in form of Urea @110 kg/acre, SSP@75 kg/acre and MOP@20 kg/acre. Before fertilizer application, carried out soil test and apply fertilizer on the basis of soil test result. Apply P and K dose if soil test show deficiency of it. If DAP is to be used, apply Urea@100 kg/acre, DAP@27 kg/acre and MOP@20 kg/acre. Apply 1/3rd dose of Nitrogen and whole dose of P and K before last puddling. Apply second dose three week after transplanting and three weeks after 2nd dose, apply remaining dose of Nitrogen. Use neem coated Urea as it will increased uptake of N. Apply Zinc sulphate heptahydrate@25 kg or zinc sulphate monohydrate@16 kg/acre at puddling to overcome zinc deficiency. Due to water scarcity, young leaves give yellow or yellow white appearance about three week after transplanting. Apply irrigation immediately also spray with ferrous sulphate@1 kg/100 ltr water per acre, two-three time with weekly intervals. Use Butachlor 50 EC @ 1200 ml/acre or Thiobencarb 50 EC @ 1200 ml or Pendimethalin 30 EC @ 1000 ml or Pretilachlor 50 EC @ 600 ml per acre as pre-emergence herbicides, 2 to 3 days after transplanting. Mix any one of these herbicides in 60 kg of sand per acre and broadcast uniformly in 4-5 cm deep standing water. For broadleaf weed control, apply Metsulfuron 20 WP @ 30 gm/acre in 150 Ltr water as post emergence, 20-25 days after transplanting. Before spray, drained out the standing water from the field and apply irrigation one day after spray. Keep field flooded up to two weeks after transplanting. When all water gets infiltrated two day after apply irrigation in field. Depth of standing water should not exceed 10 cm. While doing intercultural and weeding operation, drain out excess water from field and irrigate field after completion of this operations. Stop irrigation about a fortnight before maturity to facilitate easy harvesting. The presence of root weevil can be detected by the root and leave damage of yield. These are white legless grub feeds mainly on root. Plant gives yellow appearance, growth gets stunted and few tillers are form. If incidence is observed apply Carbaryl (4G)@10 kg either Phorate (10 G)@4 kg or Carbofuran (3 G) @10 kg per acre. These mainly occur in the irrigated wetland conditions or in rainfed areas. The presence of pest shows the browning of the yield, sooty moulds and honeydew present in bases where infected. If incidence is observed to control, spray with Dichlorvos @ 126 ml or 400 gm Carbaryl in 250 Ltr of water per acre or Imidacloprid @ 40 ml or Quinalphos 25 EC @ 400 ml or Chlorpyriphos @1 Ltr in 100 ltrs of water per acre. This pest develops in high humidity and specifically found where rice is fertilized heavily. Larva fold the leaves and eat the plant tissue and produces white streaks. Control: If infestation is observed spray crop with Cartap hydrochloride @ 170 gm or Triazophos @350 ml or Chlorpyriphos @1 Ltr in 100 Ltr of water per acre. It is serious pest in some districts. Larva create tunnel into leaves and thus destroyed leaves by producing white streaks on leaves. If Infestation is observed in field, spray crop with Methyl Parathion@120 ml or Quinalphos 25 EC@400 ml or Chlorpyriphos @1 Ltr in 100 ltr of water per acre. Larva bore into the stem and causes dead heart. The old ones produce empty ear heads which turn white. If infestation is observed in field take spray of Cartap hydrochloride @ 170 gm or Triazophos @ 350 ml or Chlorpyriphos @ 1 Ltr per 100 Ltr of water. Blast: Due to blast disease, spindle shaped spots with greyish centre and brown margin observed on the leaves. Also give neck rot symptoms and panicles get fall over. Observed in areas having excessive use of Nitrogen. If infestation is observed, spray with Zineb@500 gm/acre in 200 Ltr of water. Few grains in panicle get affected first and part of grain gets converted into black powder. In severe condition whole panicle gets affected and black powder spread on leaves, grains etc. To control this disease, avoid excess use of Nitrogen. When crop is at 10% flowering stage, take spray of Tilt 25 EC @200 ml/200 litre of water. Repeat the spray with interval of 10 days. It produces oval, eye-shaped spots with a conspicuous dark-brown dot in the centre and light brown margin. Spots are developed on grains also. In low nutrient soil, this attacked more. To keep check on this disease, give balance amount of nutrient. When crop is at boot stage take spray of Tebuconazole @ 200 ml or Propiconazole @200 ml in 200 Ltr of water. After 15 days repeat the spray. This fungus developed large greenish velvety spore-balls on individual grains. In humid, high rainfall and cloudy conditions, chances of spread of disease are high. Excessive use of Nitrogen also increases intensity of attack. To control this disease spray with 500 gm Copper Oxychloride per acre in 200 Ltr of water at boot stage in crop. With interval of 10 days, take spray with Tilt 25 EC @ 200 ml/200 liters of water. Show More On leaf sheath, greyish lesion with purple margin is developed. Later these lesions get developed and enlarge. In severe condition, poor grain filling is observed. Avoid excess use of Nitrogen. Keep field clean. If incidence of disease is observed, spray crop with Tebuconazole or Tilt 25 EC@200 ml or Carbendazim 25% @200 gm in 200 Ltrs of water per acre. Repeat the spray after 15 days interval. Reap the yield once the panicles are developing fully as well as the crops get changed significantly yellow. The yield is generally harvested manually by sickles or by blend harvester. The harvested crops, tied up into compact bundles, strike it against really hard surface to split the grains from straw, accompanied by winnowing. The post-harvest method includes some procedures which include the interval from harvest to utilization 1) harvesting 2) threshing 3) cleaning 4) drying 5) warehouse 6) milling then transport to the trade. Before the storage of grains to protect harvested stuff from pest and disease attack, mix 500 gm Neem seed dust with 10 Kg of seed. To protect stored grains from pests attacked Mix Malathion 50 EC@30 ml/3 Ltr of water. Spray for 1002meter storage area at every 15 days. 1.Punjab Agricultural University Ludhiana
