General package of practices of rice in Punjab

 

1. The non basmati cultivars, PR 113, PR 114, and PR 116 are of medium maturity group (140-145 days seed to seed) while PR 111 and PR 120 are mid early varieties (132-138 days).

2. PR 115 matures early (125 days) and PR 118 matures late (155-160 days). These cultivars fit well in rice-wheat rotation, the most predominant cropping system in the Punjab.

Planting seedlings in the main field for transplanted puddled lowland rice

1. Transplant 2-3 seedlings/hill for short duration and 2 seedlings/hill for medium

and long duration varieties.

2. Shallow planting (3 cm) ensures quick establishment and more tillers.

3. Deeper planting (> 5cm) leads to delayed establishment and reduced tillers.

4. Line planting permits rotary weeding and its associated benefits.

5. Allow a minimum row spacing of 20 cm to use rotary weeder. 6. Fill up the gaps between 7th and 10th DAT.

Root dipping for transplanted puddled lowland rice

1. Prepare the slurry with 5 packets (1000 g)/ha of Azospirillum and 5 packets (1000g/ha) of Phosphobacteria or 10 packets of (2000g/ha) of Azophos inoculant in 40 lit. of water and dip the root portion of the seedlings for 15 - 30 minutes in bacterial suspension and transplant.

Drying and Milling

2. Sun dry the harvested rice up to 12% moisture content for seed purpose and 14% for milling.

3. Cropping System: After harvest of the crop in the first week of December, mungbean

Crop stand establishment for transplanted puddled lowland rice

Optimum age of seedlings for quick establishment :

1. Optimum age of the seedlings is 18-22 days for short, 25-30 days for medium and 35-40 days for long duration varieties.

Pulling out the seedlings :

1.Pull out the seedlings at the appropriate time (4th leaf stage).

2. Pulling at 3rd leaf stage is also possible. These seedlings can produce more tillers, provided enough care taken during the establishment phase (See section 1.8 Integrated Crop Management (ICM) - Rice-SRI) through thin film of water management and perfect leveling of main field.

Insect Control in Medium deep water logged rainfed lowlands of costal

1. Possible insect pests that may attack variety Sarala are stem borer and green leaf hopper.

2. To control these, spray Metasystox @2 ml / litre of spray solution in the nursery, 15-20 days after planting and at the boot leaf stage.

3. Soak the seedlings with 0.2% Chlorpyriphos overnight before trans¬planting.

4. Early planting by the end of June reduces insect damage.

Disease Control of Medium deep water logged rainfed lowlands of costal

1. Possible diseases which may attack variety Sarala are bacterial leaf streak, bacterial leaf blight and RTV.

2. Early planting by the end of June reduces disease damage.

3. Bacterial leaf streak and bacterial leaf blight: Serious when high dose of N fertilizer is applied near the PI stage.

4. Avoid application of N fertilizer near PI stage.

5. Apply streptomycin or any other anti-bacterial chemical on observing the disease symptom.

Special technologies for problem soils for transplanted puddled lowland rice

1) For fluffy paddy soils: compact the soil by passing 400kg stone roller or oil-drum with stones inside, eight times at proper moisture level (moisture level at friable condition of soil which is approximately 13 to18%) once in three years, to prevent the sinking of draught animals and workers duringpuddling.

NPK: 60:30:30 kg/ha

FYM: 5t/ha.

Fertilizer Application

1. Direct seeding: Apply two-thirds N, entire P and half K as basal dose in furrow before seeding in waterlogged areas.

2. Apply the rest of one third of N and half K at panicle initiation as top-dressing.

3. Transplanting: Apply half N, entire P and half K as basal dose.

4. Apply one-fourth N three weeks after planting and remaining one-fourth N and half K at panicle initiation, seven to eight weeks after transplanting.
