Issues

Interventions

Lack of improved varieties and quality seeds.

· Development of varieties suited for rice fallows for which the University has already submitted a project under RKVY.

· For quality seed production four Seed Hubs and Enhanced breeder seed production programme are now operating to produce seeds as per the demand of the state.

· The present recommended varieties are OUM 11-5, OBGG-52, IPM 02-3 and IPM 02-14 of greengram; Prasad, Ujala and PU-31 of blackgram and JG-11, JAKI-

9218 and JG-14 of bengal gram in rice fallows.

Poor crop

stand and establishment

· Proper land leveling at the time of rice planting has to be done to have uniform residual soil moisture for better crop stand.

· Sowing by Zero-till planter or Line sowing behind the plough.

· Seed priming by 3-4 hours soaking in water followed by shade drying or treating the seeds with 100 ppm Manganese Sulphate or sowing overnight soaked seeds.

· Increasing seed rate by 25% (12.5 kg greengram, 12.5 kg blackgram and 25 kg bengalgram).

· Adjusting planting time of kharif rice or growing rice varieties of lesser duration.

· Seed treatment with fungicide like carbendazim (2g/kg of seed) or Thiram (3g/kg of seed) along with Ammonium molybdate @ 3g /10 kg of seeds, treating seeds by

appropriate Rhizobium culture @ 50 g/kg of seed.

Weed menace

· Application of post emergence herbicides like Quizalofop ethyl @ 50 g a.i/ha at 3 weeks crop growth stage to control monocot weeds or Imazethapyr @ 75 g a.i/ha at 15-20 days crop stage to control weeds in pulses.

Nutrient management

· The recommended N, P and K of pulses in shape of DAP and MOP should be applied to rice at PI stage.

· Foliar spray of DAP (2%) or 1% DAP + 1% MOP at 20

and 40 days after sowing to supplement N, P and K to the crops.

Micronutrient deficiencies

· Seed treatment with Ammonium molybdate @ 3g/10 kg seeds.

· Foliar application of borax@ 0.2% at flower initiation

stage in Boron deficient soil.

Terminal moisture/ heat stress

· Locally available organic mulching @ 5 t/ha.

· Conservation tillage with minimum 30% residue which act as mulching.

· Life saving irrigation to save the crop.

Lack of

mechanization

· Land leveling by laser leveler.

· Zero till seed drill / planter is to be popularized.

Diseases & pests

· Spraying Acetamiprid (60 g/acre) or Imidacloprid (50 g/acre) or Thiomethoxam (80 g/acre) with 200 lit of water against sucking pests such as white fly, aphids, thrips etc.

· Spraying 600 ml neem oil followed by Indoscacarb (200 ml) with 200 lit of water/acre to control pod borer.

· Application of 2 trichocard/acre twice for a crop, once at pod initiation stage and ten days after first application.

· Spraying Redomil MZ (400 g) alongwith Streptocyclin (20 g) in 200 lit of water to root zone of the crop to control wilt diseases.

· Spraying Sulphur wettable powder @ 800 g with 200 lit of water to control powdery mildew disease.

· Select resistant varieties for various insect pests and diseases.
