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.
3. PR 115 is suitable for multiple cropping systems, where three crops, including one of rice are grown.
4. Optimum time of sowing of medium maturity rice varieties is the second fortnight of May. Early maturing rice cultivars can give optimum yield even under late sowing conditions.
5. One month old nursery is recommended for transplanting. Among the basmati cultivars, Bas. 370 and Bas. 386 should be sown in the second fortnight of June while Super Basmati, Pusa Bas 1, Punjab Bas. 2 and Pb Mehak 1 are recommended for sowing in the first fortnight of June. Seed rate for nursery sowing is 20kg /ha.
6. Thirty three hills per m2 at a spacing of 20x15cm are recommended for transplanting in well puddled fields. Under late sown conditions higher plant population of 44 hills/m2 at a spacing of 15 x 15cm is recommended.
7. Weeds can be controlled effectively by the recommended application of herbicides. Optimum fertilizer doses have been recommended for non-basmati and basmati rice cultivars.
8. Nitrogen fertilizer doses of 120 kg/ha in three splits (1/3 basal, 1/3 at maximum tillering and 1/3 at panicle initiation stage) is recommended for non-basmati cultivars.
9. For tall basmati varieties, 18 kg urea in two splits and for others basmati cultivars; 36kg urea in two splits (three weeks after transplanting and six weeks after transplanting) is recommended.
10. Keeps water standing for 2 weeks after transplanting for better establishment and higher efficacy of applied herbicides in the fields? Thereafter, apply irrigation after 2 days when the ponded water has infiltrated in the soil upto 15 days before harvesting.
11. The frequency of irrigation should be adjusted with the rainfall. In no case, the depth of water should exceed 10 cm. 12. Integrated pest management (IPM) is being followed for protecting the crop against pests. Economic threshold level (ETL) is taken into consideration for application of insecticides.
