Seed treatment for wet nursery

1. Treat the seeds in Carbendazim or Pyroquilon or Tricyclozole solution at 2 g/l of water for 1 kg of seeds. Soak the seeds in water for 10 hrs and drain excess water.

2. This wet seed treatment gives protection to the seedlings up to 40 days from seedling disease such as blast and this method is better than dry seed treatment.

3. If the seeds are required for sowing immediately, keep the soaked seed in gunny in dark and cover with extra gunnies and leave for 24hrs for sprouting.

Crop Stand in deep water rice

1. Sow early in the season preferably during the second fortnight of March to May, in lines 20 cm apart, by drilling at a depth of 5-6 cm. Use 100 kg/ha for optimal crop stand.

2. In shallow deepwater areas where direct seeding is not feasible due to early water accumulation, transplant in the first fortnight of May with 4 to 6 seedlings/hill, with a spacing of 20 cm x 15 cm.

Land Preparation for deep water rice

1. Plough the land immediately after the harvest of the previous crop, preferably with a mould board plough.

2. Direct-seeded crop: Plough once or twice after pre-monsoon show¬ers during April or May.

3. Transplanted crop: For better weed control and nutrient availabil¬ity, do the final puddling atleast eight days after the initial one.

4. Allow the water in the field, and puddle the field twice followed by laddering.

Production technology of deep water rice

 

1. The deepwater rice ecosystem includes area having varied wa¬ter depth from 50 cm to 100 cm or higher, over a period of at least 10 days or more.

2. This ecosystem occupies a total area of 4.5 million hectares, mainly in eastern India, with an average produc¬tivity of 0.8 t/ha.

Harvesting of wet seeded puddled lowland rice

1. Taking the average duration of the crop as an indication, drain the water from the field 7 to 10 days before the expected harvest date as draining hastens maturity and improves harvesting conditions.

2. When 80% of the panicles turn straw colour, the crop is ready for harvest. Even at this stage, the leaves of some of the varieties may remain green.

3. Confirm maturity by selecting the most mature tiller and dehusk a few grains. If the rice is clear and firm, it is in hard dough stage.

Weed management and water management for wet seeded puddled lowland rice

Weed management : In wet seeded rice, pre-emergence application of pretilachlor 0.75kg/ha on 8 DAS or pretilachlor + safener (Sofit) at 0.45kg/ha on 3-4 DAS followed by one hand weeding on 40 DAS.

Water management: During first one week just wet the soil by thin film of water.

• Depth of irrigation may be increased to 2.5cm progressively along the crop age.

• An area of 800 sq.m. (20 cents) nursery is required for planting one ha of main field. Forty litres of

• spray fluid is necessary for spraying the nursery area.

Manures and fertilizer application for wet seeded puddled lowland rice

1. For direct wet seeded lowland rice, the recommendation is same at that of 

transplanted rice.

2. Apply N and K as 25% each at 21 DAS, at active tillering, PI and heading stages.

3. If N applied through LCC, use the critical value 3 for broadcasted and 4 for line sown drill seeded rice.

4. Entire P as basal applied in the last plough or at the time of incorporation of green manure/ compost.

Fertilizer Management in Basmati

1. Apply fertilizer depending on initial fertility status of soil
2. Wet season: 80:40:40:25 kg of N:P:K:Zn/ha.
Dry/Boro/Daula season:
3. 90:40:40:25 kg of NPK and Zn/ha.
4. Zinc sulphate should be applied in zinc deficient areas.
5. Basal: 40% N, 100% P, 50% K, 100% Zn.
First top dressing:
6. 30% N, 30-40 days after planting, but 10 days before panicle initiation.
7. Second top dressing: 30% N & 50 % K at initial grain filling (early milk)

After cultivation in wet seeded puddled lowland rice

1. Thinning and gap filling should be done 14 - 21 days after sowing, taking advantage of the immediate rain.

2. If dual cropped with green manure, incorporate the green manure when grown to 40cm height or at 30 days after sowing, whichever is earlier, using Cono-weeder.

3. Green manure incorporated fields may be operated again with rotary weeder a week later in order to aerate the soil and to exploit organic acids formed if any.

Land Preparation of Basmati

1. Dry ploughing should be done 2 times in the summer followed by application of FYM @ 2 tons/ha.
2. Puddle 2-3 times at 3-4 days interval for a fine puddle.
3. Level the land with a leveler to maintain uniform water levei throughout the plot.
4. Apply and incorporate basal fertilizer dose before laddering.

Seed Treatment of Basmati

1. To prevent some soil borne diseases for dry sowing, treat the seed with Agroson GN, Cerasan(dry) or Bavistin @ 2 g/kg of seed.
2. For wet sowing treat the seed with Streptocycline @1.5/ gm + 20g Captan in 20 I of water for soaking 10 kg of seed, soak for 10 hrs, shade dry the treated seed before sowing drain the water, and cover the seed in gunny bags or under shade, for germination.
3. This protects the variety from sheath blight, blast and bacterial leaf blight.

Seed selection & Seed rate of Basmati

1. Seed, a basic input, contributes for 15 % of production.
2. Prepare salt solution of 1.06 specific gravity by dissolving common salt @ 60gm/l of water.
3. Pour the seed into the solution and remove the floating materials.
4. Wash the selected seed in fresh water.
5. Seed rate: 3Q-35 kg/ha for sowing in nursery.
