GREENGRAM ( Vigna radiata L. )      

Seed Treatment With Biofertilizer

Treat the seeds with one packet (200 g/ha) of Rhizobial culture CRM 6 and one packet (200 g/ha) of Phosphobacteria one packet (200 g/ha) of PGPR developed at TNAU using rice kanji as binder. If the seed treatment is not carried out apply 10 packets (2 kg) of Phosphobacteria and 10 packets (2 kg) of PGPR with 25 kg of FYM and 25 kg of soil before sowing.

Fertilizer Application

  • Apply fertilizers basally before sowing.
       Rainfed  : 12.5 kg N + 25 kg P2O5 + 12.5 kg K2O +10 kg S*/ha
       Irrigated : 25 kg N + 50 kg P2O5 + 25 kg K2O + 20 kg S*/ha

*Note : Applied in the form of gypsum if Single Super Phospate is not applied as a source of phosphorus

  • Soil application of 25 kg ZnSo4/ha under irrigated condition   
  • Soil application of 25 kg ZnSo4/ha under irrigated condition
  • Soil application of TNAU micronutrient mixture @ 5 kg/ha as Enriched FYM (Prepare enriched FYM at 1:10 ratio of MN mixture & FYM ; mix at friable moisture &incubate for one month in shade).

Multi-blooming technology for irrigated green gram in new delta region of Thanjavur

For higher yield and income, apply 25:50:25:20 kg NPKS/ha.+25 kg N/ha. in 3 equal splits on 30, 45 and 60 days after sowing + 2% DAP spray on 45 and 60 days after sowing.

Foliar spray of 1% urea for yield improvement in green gram

For yield improvement through increasing the physiological, biochemical attributes, foliar spray of urea 1% on 30 and 45 days after sowing is recommended. For rice fallow pulses in Delta area, the present recommendation of foliar spray of 2% DAP may be continued.

Economizing the use of micronutrients through seed treatment for greengram

Seed coating with biofertilizers and micronutrients viz., Zn, Mo & Co @ 4,1,0.5 g/kg of seed is recommended.

Multi Bloom Technology

A special technology being practiced in Pattukottai block of Tanjore district for blackgram and greengram.

The soil is alluvial and rich in organic matter and nutrients. The crop is sown during early summer (Jan.-Feb.) as  normal crop and fertilizer is applied as per the recommendation for irrigated crop. In addition to that, top dressing of Nitrogen is done with an extra dose of 25 to 30 kg through urea. Since pulses are indeterminate growth habit and continue to produced new flushes, the top dressing will be done on 40-45 days after sowing.

The crop complete its first flushes of matured pods during 60-65th day and put further second new flush within 20-25 days. Therefore two flushes of pods can be harvested at a time within the duration of 100 days.

RICE-FALLOWS

Foliar Spray

  • Foliar spray of  NAA 40 mg/litre and Salicylic acid 100 mg/litre once at pre-flowering and another at 15 days thereafter
  • Foliar spray of pulse wonder @ 5 kg/ha once at flowering or DAP 20 g/lt once at flowering and another at 15 days thereafter
