- Five splits of nitrogen at 20%
basal, 25% at 4- leaf stage, 30% at 8- leaf stage, 20% at tassel emergence and
remaining 5% at early grain filling stage is best nitrogen utilization, higher
yield and net returns.
cropping system is suitable for improvement of organic carbon, available N and
available P in zero tillage than conventional tillage.
- Intercropping of two rows of
groundnut in paired row maize (45/90 cm) is more profitable compared to
intercropping of mungbean, urdbean, cowpea and soybean.
optimum plant population for rabi
maize is 80 thousands/ha and row distance is 60 cm with 150 kg N, 60 kg P2O5
and 40 kg K2O/ha for productivity optimization.
spring season, application of rice straw mulch @ 5 t/ha after 2nd
irrigation is effective in increasing productivity, net return and irrigation
water use efficiency.
bed with or without residue conservation is better than conventional tillage
method on Mollisols of tarai region
application of recommended dose of N, P and K through chemical fertilizers
along with farm yard manure 5 t ha-1 increases productivity and
nutrient uptake by maize and wheat, increases soil organic carbon and
sequestration and maintaining soil health in maize-wheat rotation in mollisols.
stalk rot of maize can be managed efficiently by soil application of bleaching
powder @ 25 kg/ha at the time of flowering followed by second application after
10 – 12 days. Through irrigation water, bleaching powder (3%) @ 16.5 kg/ha at
the time of disease appearance or at flowering is recommended for BSR.
- For the
management of Brown stripe downy mildew, 4 – 6 foliar spraying of mancozeb
(0.3%), Captan (0.2%) at 7 to 10 days intervalor three foliar spray of Zinc Sulphate + Lime
(0.5% + 0.25%) and Copper sulphate (0.1%) at 7 days interval. Seed treatment
with Metalaxyl 35% WS @ 7 gm/kg seed followed by foliar spray of mancozeb 75%
WP or Metalaxyl 8% + Mancozeb 64% WP @ 2 – 2.5 kg/ha is also effective for managing Brown stripe downy mildew.
- Chopped green paddy stem with 10%
sucrose and peptone was found the best substrate for mass production of Rhizoctonia solani for artificial
inoculation under field conditions
chemical management of banded leaf and sheath blight, two foliar spraying of
Propiconazole 25 EC/ Dinfenconazole 25 EC @ 0.1% at 10-15 days interval was found effective.
Newer compounds Pencycuran 250 SC @ 0.1% or Azoxystrobin 250 Sc @ 0.05%
was found effective for the management of BLSB. Soil application of Trichoderma
harzianum impregnated FYM @ 100kg/ha and seed dressing with the same @
2.5g/ka seed gave the highest disease control and yield.
management of Post flowering of stalk rot seed treatment with Benlate (2 gm/kg
seed), drainage of water at the time of flowering and irrigation in case of
moisture stress was found effective in minimizing the disease incidence.
- For the
management of Maydis leaf blight two spraying of mancozeb 75WP or Zineb 75WP @
2 – 2.5 kg/ha at 10 to 15 days interval is recommended.
