Organic Package for Rice- Barley+Mustard- Summer Moong System is given below:-
1.Rice
Suitable varieties:
‘Saket-4’ and other low input requiring and resistant varieties to insect pest and diseases.
Sowing time:
The appropriate time for transplanting of rice is the first week of July.
Seed rate and nursery raising:
Optimum seed rate for nursery raising of rice is 25 kg/ha.
Transplanting and Spacing:
Normally 25-day old seedlings should be transplanted in the well-puddled field at the row to row /plant to plant distance of 20 and 15 cm, respectively.
Nutrient management:
- Well rotten FYM @ 10.0 t/ha should be incorporated into the soil at least 20 days
before puddling. - Vermicompost @ 5.0 t/ ha should be top dressed before second irrigation.
- Biofertilizers like Azotobactor (nitrogen fixer) and Phosphorus Solubilizing. Bacteria (PSB) each should be added @10 kg/ha in the soil after final land preparation.
Water management:
Depending upon the amount and frequency of rains during the growing season 10-12 irrigations (5 cm water/ irrigation) should be applied intermittently.
Weed management:
To control the weeds effectively in rice, the field should be well puddled. The weeds can be effectively controlled manually by two hand-weeding at 20 days interval.
Plant protection:
- Solar seed treatment for 2-3 hours during May-June for seed borne diseases like bacterial leaf blight.
- Seedling treatment with Pseudomonas fluorescence culture @ 4 kg/ha and Trichoderma harzianum culture @ 5 kg/ha for soil borne diseases.
- Foliar application of garlic + green chillies paste (1:1) @10 kg/ha for the gundhi bug.
- Field release of Tricho-cards (Tricogramma japonicum) 5-6 times @ 30 cards/ha for stem borer and leaf folder.
- Foliar spray of Pseudomonas fluorescence at dough stage for sheath blight.
2.Barley + mustard (4:1)
Suitable varieties:
Barley variety ‘Azad’ with mustard variety ‘Pusa Bold’ and other low input requiring and resistant varieties of crops to insect pest and diseases.
Sowing time:
In the rice-barley + mustard-summer moong cropping system, barley + mustard can be sown optimally up to the first week of November.
Seed rate:
Optimum seed rate for sowing barley is 80 kg/ha and for mustard is 4 kg/ha. In intercropping (4:1) 60 kg seed of barley and 2 kg seed of mustard will be sufficient. Organically certified seed should be preferred for sowing.
Spacing:
In barley, row to row 20 cm and plant to plant 5 cm distance should be maintained while, in each 5th row in the field at same row distance mustard can be sown keeping plant to plant spacing of 10 cm.
Nutrient management:
- Well rotten FYM @ 8.0 t/ha should be incorporated into the soil at least 20 days
before puddling. - Vermicompost @ 4.0 t/ ha is top dressed before second irrigation.
- Biofertilizers like Azotobactor (nitrogen fixer) and Phosphorus Solubilizing.
Bacteria (PSB) should be applied each @10 kg/ha in soil after final land
preparation.
Water management:
The crop should be irrigated at critical crop growth stages. Five irritations including pre-sowing irrigations are sufficient for raising barley+ mustard intercrops.
Weed management:
Weeds under organic cultivation of barley + mustard can be
easily managed by two manual intercultural operations depending upon the severity of
weeds.
Plant protection:
- Use certified seeds and grow resistant varieties for covered smut
- Early/timely sowing of mustard to avoid white rust.
- Spray neem based insecticides for mustard aphid.
3.Summer moong
Suitable varieties:
Variety ‘Pusa Vishal’ and other low input requiring and resistant varieties to insect pest and diseases can also be grown.
Sowing time:
Followed by barley + mustard, summer moong can be sown optimally up to the second week of April.
Seed rate:
20 kg/ha.
Spacing:
Row to row 30 cm and plant to plant 10 cm distance should be maintained.
Nutrient management:
- Vermicompost @ 2.0 t/ha should be top dressed before second irrigation.
- Biofertilizers like Rhizobium @ 200g/10kg seed as seed treatment and Phosphorus
Solubilizing Bacteria (PSB) @10 kg/ha should be applied as a soil treatment.
Water management:
Besides the pre-sowing irrigation moong crop can be raised successfully by applying 2-3 irrigations during summer.
Weed management:
Being weed smothering crop, weed in summer moong is not a problem. However, need basing one manual intercultural operation can be done.
