Diabetic-Friendly Rice, the true gem of this method, allows individuals with diabetes to enjoy delicious Rice without compromising their health.

RNR 15048 Paddy Facts

Telangana Sona (RNR 15048) is a remarkable rice variety born from the crossbreeding of MTU 1010 and JGL 3855 using the pedigree method. This short, slender, and super fine Rice is perfect for Kharif and rabi seasons. It boasts a semi-tall stature, a short growth cycle (125 days), and impressive high yields of 6500-7000 kg/ha.

The variety resists blast disease, making it suitable for late sowing conditions. Moreover, it shines in head rice recovery with a rate exceeding 67%. One of the most outstanding features of Telangana Sona is its low glycemic index (GI) of 51.0. This characteristic makes it an excellent choice for those seeking healthier dietary options, as it causes a slower and steadier increase in blood sugar levels after consumption.

Soil Preparation and Seed Selection for RNR 15048 Paddy Cultivation

Sowing Time and Nursery Management (Wet)

  • Sow nurseries between November 10th and December 15th.
  • Plow the nursery field twice, followed by 2-3 puddling sessions at 5-6 days intervals.
  • In slightly saline soils, drain out standing water after puddling.
  • Create one-meter-wide raised beds with irrigation channels to level the field after the final puddling.
  • Add well-decomposed FYM/compost at 200 kg/5 cents nursery to improve soil condition.
  • Treat seeds with carbendazim (1g/kg) or Dithane M-45 (2.5g/kg).
  • Soak paddy seeds for 24 hours, incubate for 24-36 hours, and sow sprouted seeds in the nursery beds.
  • Apply 2 kg Nitrogen, 1 kg ‘P2O5,’ and 1 kg ‘K2O’ per 5 cents nursery bed.
  • Sow sprouted seeds at 5 kg/cent (40 m2) or 25 kg for a 4-5 cents nursery, enough for one acre of the main field.
  • Cover the nursery with polythene sheets at night to protect it from cool temperatures.
  • Frequent draining and higher nitrogen can increase nursery growth and prevent salt injury.
  • Treat zinc deficiency with zinc sulfate spray (2.0 g per liter).
  • Address blast incidence with appropriate chemicals like Tricyclazole, Carbendazim, Isoprothiolone, Kasugamycin, or Ediphenphos.

Main Field Conditions

  • Start puddling at least 15 days before transplanting.
  • Tractor/power tiller puddling to 15 cm depth is sufficient.
  • Level the field perfectly after final puddling and let it settle for 2-3 days before transplanting for better water and weed control.

Planting Techniques and Timing for Optimal Growth

  • RNR 15048 Paddy Characteristics: RNR 15048 paddy is a low-GI (Glycemic Index) rice variety with a GI value 51.0. It is a short, slender, and super fine rice type that exhibits resistance to blast disease. This variety has high head rice recovery, above 67%, and is suitable for late sowing conditions.
  • Transplant 4-6 leaf age rice seedlings, but avoid tender seedlings in slightly saline soils.
  • Drain the main field frequently and perform inter-cultivation to prevent mortality due to salinity and cold.
  • Transplant minimum 44 hills/m2 at 2-3 cm depth with 2-3 seedlings/hill.

Water Management in Paddy Fields for RNR 15048 Rice Cultivation

Proper water management for successful RNR 15048 rice cultivation offers numerous benefits, like improved tillering, increased nutrient utilization, and reduced weed growth.

  1. Transplanting: Maintain a shallow water depth of 1-2 cm during transplanting to ensure optimal conditions for seedlings.
  2. Crop Establishment: After transplanting, gradually increase the water level to a depth of 5 cm to facilitate crop establishment.
  3. Tillering Phase: During the tillering phase, maintain a shallow water depth of 2-3 cm to support healthy growth.
  4. Panicle Initiation to Maturity: Maintain a water depth of 5 cm from panicle initiation until the physiological maturity stage, about ten days before harvest.
  5. Water Stress Prevention: Avoid water stress during critical stages like panicle initiation, flowering, and milk to ensure proper development and yield.

Nutrient Management and Fertilizer Application in Paddy Fields

  1. Balanced Fertilizer Use: To enhance soil fertility and productivity, integrate organic, inorganic, and biofertilizers in a balanced manner.
  2. Green Manures/Compost: Incorporating 25-30% of recommended nitrogen (N) through green manures, compost, FYM, or poultry manures can result in sustainable yields.
  3. Fertilizer Ratios: Apply N, P2O5, and K2O at a 120:60:40 kg/ha ratio. Apply all P2O5 and K2O as basal, and divide N into three equal splits (basal + active tillering + panicle initiation). For light-textured soils, apply K2O in two splits – half at basal and half at panicle initiation, along with the last top dressing of N.
  4. Nitrogen Topdressing: Drain the field before N topdressing and irrigate after two days only.
  5. Phosphorus Topdressing: Avoid topdressing phosphorus or phosphorus-containing complex fertilizers after 15 days of planting.
  6. Zinc Deficiency: Apply Zinc Sulphate at 50 kg/ha to prevent Zn deficiency. Correct deficiency in the standing crop by spraying zinc sulfate at 0.2% (2g/l of water) and repeat as needed based on the severity of the problem.
  7. RNR Paddy Variety Duration: RNR 15048 paddy variety is typically around 125 days, making it a short-duration rice variety suitable for kharif and rabi seasons.
  8. RNR 15048 Paddy Market Price: The market price of RNR 15048 paddy may vary depending on the region, demand, and supply. For the most accurate and up-to-date market price information, it is recommended to check with local agricultural markets, rice traders, or agricultural authorities.
  9. To obtain RNR-15048-Diafit paddy seeds, interested farmers and growers can approach reputable agricultural research institutions, state agricultural universities, certified seed suppliers, or government-approved seed agencies. They are reliable sources that can provide genuine and quality seeds of RNR-15048-Diafit paddy.
