Land Preparation for Rainfed Upland rice

 

1. With the initial summer rainfall, prepare the field. Plough the field well. Use the disc harrow twice. Apply farm yard manure at 10 t/ha.

2. Apply lime every 3 years. Determine dosage after soil testing. Furrow application of lime will reduce lime requirement. Ensure proper leveling of the field before sowing. Make uniform rows at 25cm distance.

3. Use a row marker for making shallow furrows (rows). Apply basal dose of fertilizer (20 kg N, 60 kg P, 40 kg K/ha) and carbofuran granule (1kg a.i./ha) in furrows before seeding and mix well.

Animal Drawn Light Ridger Plough

It is a light duty, double mould board with reversible share type plough suitable for ploughing and making ridges in light soils and hilly terrains. The implement can be effectively used for upland cultivation. Compared to conventional method of using spade for making ridges, this animal drawn implement has high capacity. It is superior over local plough and can be adopted in light soils and hilly terrains.

Harvesting of Rice Crop

 

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. 4. When most of the grains at the base of the panicle in the selected tiller are in a hard dough stage, the crop is ready for harvest. At this stage harvest the crop, thresh and winnow the grains.

Weed Management in Rice

 

Weed Management Practices in Direct Sown Rice:

1. By ensuring thorough land preparation, the weed can be minimized. Summer ploughing is generally recorded for facilitating stubble management as well as weed control.

2. Rain water conservation, preparation of seed bed before sowing by way of providing one round harrowing and levelling after the land preparation minimizes weeds.

3. The fields should be given summer ploughing to destroy perennial weeds. Stale seed bed should be prepared by thorough seed bed preparation.

4. Timely sowing of crop may be encouraged to minimize crop weed competition.

5. The crop should be sown in lines at recommended spacing to facilitate inter weeding operation. The mechanical methods of weed management should be practiced after 2-3 weeks and second time if necessary after 4-6 weeks of sowing.

6. Apply Cyhalohop-Butyl @ 75-80g a.i. /ha at 18-20 days after sowing in grassy weeds in direct seeded rice followed by one hand weeding given after 4-6 weeks has been observed effective.

Weed Management Practices Under Low land Rice:

1. Bunds and irrigation channels should be kept free from weeds.

2. Summer ploughing should be practiced wherever possible to destroy perennial weed vegetation.

3. Stale seedbed should be prepared wherever possible .Pudding should be done immediately before transplanting of rice.

4. As far as possible, rice seedling should be free from weed seedlings at the time of transplanting.

5. Optimum plant population and application of recommended rate of nutrients application would help to ensure adequate density of plants population which could minimize the competition from weeds.

6. Maintain a thin layer of water on the soil surface to minimize weed growth under such conditions.

7. Early weeding 3-4 weeks after transplanting in case where mechanical methods are to be used.

8. One hand weeding may be given 4-6 weeks af

Water Management in Rice

 

Water Management in Transplanted rice :

1. Continuous submergence of 2-5 cm during crop growth (transplanting to maturity) gave higher yield. This practice helps to suppress weed growth right from the beginning.

2. Water is drained out during fertilizer application. The depth of water should not exceed 5 cm in the field particularly at the tillering stage of the crop.

3. Higher depth of water during tillering reduces the number of tillers/hill causing reduction in yield. After the completion of tillering, the field should be drained out for a week and reflooded again.

4. This will result in higher number of effective tillers/hill. In any case, there should not be any water stress during panicle initiation to grain filling stage.

5. Irrigation should be stopped 3-4 weeks before harvesting the crop. Under SRI practice no flooding is needed and field is kept saturated. No standing water to be maintained during tillering up to panicle initiation. Intermittent wetting and drying until panicle initiation stage is desirable. The period of drying and wetting can range from 2-7 days.

Water Management in Direct seeded rice:

1. Cultivation of crops in toposequence helps in better utilization of water in hill slopes and terraces.

2. While rice is cultivated in terraces or slopes, it should be grown in the lower portion of the hill slope where runoff concentrates.

3. Water harvesting in-situ in flat or terrace land can be done by providing peripheral bunding to increase crop yield. Saturation and submergence are equally effective for direct sown rice

Manure and fertilizers

 

a) Direct sown:

In upland direct seeded crop, application of 60 : 60 : 40 kg Nitrogen (N) in the form of urea or ammonium sulphate, Phosphorus (P) in the form of single super phosphate and Potash (K) as Murate of potash should be applied.

Full dose of P and K should be applied at sowing in furrow below the seed while N dose may be divided into 3 equal splits i.e. 1/3 rd applied at the time of sowing, next 1/3rd just after first weeding (25-30 days of crop age) and last 1/3rd dose at the panicle initiation stage.

Integrated application of 60:60:40 kg NPK/ha + FYM @ 5t1ha is recommended for higher productivity and maintenance of soil health.

b) Transplanted:

Application of fertilizer @ 80:60:40 kg NPK/ha is considered sufficient for transplanted rice in low valley land as well as terrace land.

This dose will vary according to the fertility status of soil. All P and K and 50% of N should be applied as basal dose and 25% N at maximum tillering and 25% at panicle initiation stage.

In zinc deficient soils, application of zinc sulphate (ZnS04) @ 25 Kg/ha at the final land preparation is useful. During the application of fertilizer (Top-dressing) the soil should be moist.

Heavy irrigation should be avoided. Application of well decomposed organic manures like FYM @ 10 t/ha or enriched compost @ 5t/ha (mixed with 60 kg P using Rock phosphate and incubating for 30 days) along with 50% NPK improve yield and soil health.

Sowing / Transplanting time

B) Transplanting: 1. 20 x 10 cm. 2. 10 x 10 cm, if transplanting is delayed.

3. High and mid altitude areas: 4 -5 seedlings/hill.

4. Low altitude/valley land: 2 to 3 seedling/hill.

Methods of Sowing

 

1. Direct sowing: Four ploughings are necessary for getting good tilth and well-pulverised soil.

Apply lime @ 2 t/ha at least 1-2 weeks before sowing every3rd year.

Lime should be applied at least 1-2 weeks before sowing. Liming should be repeated every 3-4 years.

All the phosphorous and Potash should be placed in furrow before sowing.

2. Transplanting: Prepare the land thoroughly and keep well levelled with peripheral bun

ding.

Puddling should be done 3 to 4 times to make the land weed-free and water retentive.

All the Phosphorous andPotash and 50 % of nitrogen should be incorporated thoroughly into the soil at the finalpuddling.
