Seeds and Seeding

  • In Kharif mid June to mid September is optmum for sowing.
  • Seed rate of 10kg ha-1 is adequate for a spacing of 90x20 or 180x10cm.
  • In light soils, adopt 60x20cm spacing.
  • For long duration varieties a seed rate of 5-6kg/ha with a spacing of 180x10cm to 150x12cm should be adopted to facilitate intercropping depending on soil type.
  • For short duration varieties adopt a spacing 90x20cm in black soils and 60x20cm in light soils.

Fertilisers

  • Apply 20N + 50 P2O5 kg ha-1 as basal dose. Treat the seed with Rhizobium culture.

Weed Management

  • One or two hoeings keep the crop from weeds up to 60 DAS or application of fluchloralin @ 2.5 /ha-1 as pre-sowing incorporation checks the weeds (or) spray pendimethalin @ 3.3 – 5.0/ha immediately after the sowing or the next day.

Pest Management

  • Follow IPM for Heliothis on Redgram

Cultural

  • Summer ploughing
  • Avoid monocropping
  • Follow crop rotation
  • Avoid staggered sowing
  • Adopt wider row spacing (more than 2 meters)
  • Use recommended dose of fertilisers.
  • Cultivate tolerant / recouping varieties (ICPL 332, ICPL 84060, LRG 30, MRG 66, LRG 41).
  • Grow Intercrops.

Kharif : Sorghum, Soybean, gingelly, greengram, blackgram, greengram, dry paddy and bajra.

Mechanical Methods

  • Monitor with Pheromone traps @ 10nos ha-1.
  • Dislodge the larvae by jerking the plants.

Biological Methods

  • Release Trichogramma twice at weekly intervals @ 65000 ha-1
  • keep bird perches @ 50 ha-1
  • Spray NPV and B.T (NPV @ 500 LE /ha or B.T@ 1kg ha-1)

Plant products

  • Use Neem oil @ 5ml l-1 or repelin @ 10ml l-1 or NSKE @ 50g l-1.

Chemical Methods

Follow need based application

  • Mixtures should not be used
  • Aim the sprayings at early instars
  • Apply endosulfan @ 2.0 /ha-1 or chlorpyriphos @ 2.5 / ha-1 or Quinalphos @ 2.0/ha-1 or acephate @ 1.0kg ha-1 alternatively during the flowering and pod formation stage.
  • Use Hydraulic / Pneumatic hand compression sprayers (900-1000 Lha-1).
  • Ensure thorough coverage (900-1000 L ha-1).
  • Discourage synthetic pyrethroids
  • Avoid sublethal dosages
  • Adopt community approach

Pod fly : Monocrotophos 1.6ml l-1 or acephate 1g l-1 at the time of seed development on need basis.

Disease Management

  • Wilt : Grow resistant varieties, ICPL 87119 and ICPL 8863, PRG 100 and ICPL 227. In endemic areas crop rotation with sorghum or tobacco.
  • Sterility mosaic virus : Grow resistant varieties, ICPL227 and ICPL 87119. Spray wettable Sulphur 3g or dicofol 3-5 ml l-1 twice at weekly intervals against eriophid mite to avoid disease spread. Avoid perennial pigeonpea.
  • Macrophomina Blight : Grow resistant variety, MRG 66
  • Harvesting : Properly dried produce can be stored in nylon bag, polythene lined gunny bag or compactly knitted gunny bag up to a period of 180 days.

Recommendations :

  • Grow medium duration pigeonpea only as intercrop in groundnut, sorghum, maize, bajra, greengram, blackgram, and soybean (1:7 to 1:2) to reduce Helicoverpa pod borer damage. Increase proportion of pigeonpea in groundnut (1:7).
  • Grow wilt and wilt + sterility mosaic resistant varieties such as ICP 8863, ICPL 222, PRG 100, ICPL 87119 in disease endemic areas especially in S.R.Zone. Select PRG 100, ICP 8863 for light soils.
  • Medium duration pigeonpea (180 days) is a good contingency crop for late sowings.
  • Use Helicoverpa pod borer tolerant line LRG 41 as component of IPM for pod borer. Follow intercropping and plant shaking. Erect bird perches and pheromone traps and use botanical (Neem-based) and bio-pesticides (NPT, Bt).
  • Grow pigeonpea on paddy field bunds in single paddy crop areas.

Recommendations for increasing the production of Kharif pulses in the A.P State

Crop

Recommendations

Pigeonpea

Grow short varieties such as ICP 8863, PRG-100 in light soils and low rainfall areas.

Follow optimum spacing 1.8-2.4m x 30cm in heavy soils and 1.5mx30cm in light soils

Conserve soil moisture by intercultivation at the end of the rainy season

Control pod borer through IPM

Greengram

Sow at optimum time June 15 to July 15

Blackgram

Follow seed treatment with carbosulfan (30g/kg seed), against sucking pests and viral diseases.

Critical interventions in major pulse crops in different districts and campaign issues to reduce cost of production and increase income.

Major pulse crops

Critical Interventions

District / Zones

Stage of Intervention

Pigeonpea

1. Select short duration varieties of 150-175days (PRG-100 Maruti) for light soils and low rainfall areas to escape from terminal moisture stress.

Scarce Rainfall Zone, Southern Telangana Zone and Southern Zone.

  5. Erection of bird perches during reproductive stage (20/acre).
  6. Use of bio-control agents such as NPV (200 LE /acre), Bt (400 g/acre). Need based use of pesticides such as endosulfan, chlorpyriphos or quinalphos.
