Nutrient Management

APPLICATION OF FERTILIZERS

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 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).

Foliar spray of 1% urea for yield improvement in black 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.

Foliar spraying to mitigate moisture stress

Foliar spraying of 2%KCl + 100 ppm Boron during dry spell as mid season management practice in black gram during Rabi season is recommended to increase the yield over KCl spray alone .

Economizing the use of micronutrients through seed treatment for blackgram

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

Nitrogen substitution by organic sources for pulses

50 per cent nitrogen can be substituted through organic source (850 kg of vermicompost per hectare).
Lime application is recommended for pulses with soil pH less than 6.0.

Nutrient Management :: Redgram

TREATMENT OF THE SEEDS WITH BIOFERTILIZER Fungicide (or) bio control agents treated seeds should be again treated with bacterial culture after 24 hours. Treat the seeds required for sowing 1 ha with Rhizobial culture CRR 6 / CPR 9, phosphobacteria (Bacillus megaterium) and PGPR (Pseudomonas sp.) developed at TNAU, with one packet each (200g). For red lateritic soil, Rhizobial culture VPR 1 is effective. Using rice kanji as binder, Rhizobium should be given as seed treatment only. For PSB and PGPR, if the seed treatment is not carried out, apply 10 packets (2 kg) of Phosphobacteria (Bacillusm megaterium) and 10 packets (2 kg) of PGPR (Pseudomonas sp.) with 25 kg of FYM and 25 kg of soil before sowing.

SPRAYING OF DIAMMONIUM PHOSPHATE OR UREA, NAA AND SALICYLIC ACID Foliar spray of NAA 40 mg/l once at pre-flowering and another at 15 days thereafter Foliar spray of DAP 20 g/l or urea 20 g/l once at flowering and another at 15 days there after Foliar spray of salicylic and 100 mg/litre once at preflowering and another at 15 days there after PERENNIAL REDGRAM Fertilizer application : Urea 15 g and superphosphate 30 g / pit.
