Objective

          The Regional Research and Technology Transfer Station, Keonjhar was established in 1978 to cater to the research needs of the North Central Plateau Zone comprising of Keonjhar and Mayurbhanj districts of Orissa.

          The climate of the zone is hot and sub-humid with mean summer maximum temperature of 36.6oC and mean winter minimum temperature of 11.1oC. The mean annual rainfall is 1591 mm of which about 80% is received during June to September. Out of the total annual rainfall about 6% is received during Rabi (October to January) and about 14% during summer (February – May). The cultivated area is 18.71 lakh. The cropping intensity of the zone is 131%. The irrigated area is about 22% in kharif and 11% in Rabi seasons. The lead function of the zone is Rainfed farming.

          The soils of the zone are red (75%),mixed red and black (5%) and red and yellow. These soils are mostly acidic, light textured and with low fertility.

Crop Production Technology Generated For Rainfed Uplands

  1. Groundnut, arhar and maize are most suitable for substitution of upland rice and yielded 15.2, 17.0 and 31.9 q/ha, respectively,while rice under favourable weather could yield upto 16.5 q/ha. with risks of its failure under drought situations.

  2. Promising arhar based intercropping system with their planting pattern for rainfed high lands are :

Intercropping   system 

Row ratio

Planting pattern(cm)

Inter and intra row spacing intercrop(cm)

Arhar + groundnut

2 : 8

50-180-50

20 cm x 10 cm

Arhar + runnerbean

2 : 1

30-120-30

60 cm x 22.5 cm

Arhar + rice

2 : 10

50-165-50

15 cm solid row

  1. In rainfed uplands where rice and arhar are sown together in mixed cropping, a seed rate requirement of 60% rice and 40% arhar is the ideal combination. Rice and arhar when broadcasted in the above proportion have yielded 11.5 and 12.2 q/ha, respectively but when line sown in paired rows (2:10) in planting pattern of 50-165-50cm gave an additional yield of 3.5 and 2.5 q/ha for the corresponding crops, respectively.

  2. Upland rice yield increased by 10% with the use of Azospirillum.
  3. Fertilizer management schedule for upland rice :

Full P2O5 and K2O @ 20 kg/ha each to be applied basally in furrows during sowing. N is to be applied @ 40 kg/ha in two splits (50% N at 15 and rest at 40 days after sowing).

  1. Maximum green fodder yield of 470 q/ha is obtained in rainfed uplands with mixed cropping of maize and cowpea.

  2. For non-irrigated uplands, horsegram (15.0 q/ha) and castor (9.5 q/ha) are two important pre-rabi crops following kharif rice(16.5 q/ha), maize (35.0 q/ha) and greengram (6.5 q/ha).

For Rainfed Medium Lands

  1. Fieldpea and bengalgram are most remunerative as paira crop after rice in rainfed medium land. Two percent DAP spray twice (45 and 60 DAS) in paira fieldpea resulted in 15% yield advantage (23.0 q/ha) over control.
  2. Continuous application of 10 kg BGA /ha to medium land rice renders grain yield advantage equivalent to 20 kg N/ha.
  3. Application of 40 kg P2O5/ha to green manure crop dhanicha preceeding rice and 39 kg N/ha to rice gave satisfactory grain yield (5 t/ha) with 25% yield advantage over full dose of N (@ 60 kg/ha) applied to rice. Alternatively, application of FYM @ 5t/ha with 35 kg N/ha to rice also enhanced the productivity of rice (4.5 t/ha).
  4. Productivity of local medium land rice cv. Suryakanti can be enhanced from 2.6 to 4.0 t/ha with application of sub-optimal dose of 30 kg N, 15 kg P2O5 and 15 kg K2O/ha.
  5. Direct sown medium land rice cv. Lalat to be most productive, full P2O5 and K2O along with 25% recommended N should be applied basally. Rest N can be topdressed in two splits i.e. 50% at beusaning/ khelua and 25 % at PI stage.
  6. In medium land rice (135 days duration) N can be applied in 3 splits (25% as basal, 50% at tillering and 25% at PI) for attaining maximum N use efficiency and yield.
  7. Cultural practices for rainfed medium land rice :

i) In direct sown medium land rice if beusaning is not possible due to low rainfall, the crop as such can be weeded and fertilized without much reduction in yield..

ii) Direct dry seeding gives as good yield as that of transplanting if plant population is kept optimum .

iii) With optimum plant population, random and line transplanted rice are found equally productive .

  1. The optimum time of sowing of wheat was observed to be second fortnight of November. The crop sown during this period yielded 4.5 t/ha but with delay in sowing (i.e. December) 28-38% reduction in yield was noticed.
  2. Optimum fertilizer requirement for maize under rainfed situation has been worked out to be 120 kg N, 40 kg P2O5 and 40 kg K2O/ha for achieving a grain yield of 4.2 t/ha.
  3. Optimum time for sowing, kharif and pre-rabi greengram are first fortnight of June (with cv. Hyb. 12-4 yielding 7.5 q/ha) and first fortnight of September (with cv. Nayagarh local yielding 7.6 q/ha) respectively.
  4. Inoculation of Rhizobium culture to grain legumes viz., arhar, blackgram, soybean and groundnut enhanced the yield by 20% and saved N by 50% in groundnut and soybean.
  5. The optimum fertilizer dose for arhar was found to be 20 kg N and 40 kg P2O5 / ha which resulted in 8.3 q/ha extra yield over control.
  6. Optimum time of sowing runner bean is 15th June in kharif and 30th October in Rabi.
  7. In rainfed medium land lentil cv. B 77 sown during 1st fortnight of December with optimum seed rate (40 kg/ha), spacing (22.5 cm x 5.0 cm) and fertilizer dose (25 : 30 : 30 kg of N: P2O5 : K2O/ha) can yield 5.5 q/ha.
  8. Optimum fertilizer dose (60:30:30 kg N:P2O5 : K2O/ha) has been worked out for mustard cv. RLM 514 under irrigated conditions with a yield of 12.0 q/ha.
  9. Sowing kharif sunflower cv. Morden on second fortnight of June at spacing 60 cm x 30 cm was found to be quite ideal in respect of yield (14.5 q/ha).
  10. In moisture retentive rice fallows, safflower cv. A. 300 sown during first week of December at 30 x 15 cm spacing and fertilized with 60 :40:20 kg N:P2O5 : K2O/ha showed reasonable yield of 10 q/ha.
  11. Promising linseed cv. T-397 can yield upto 4.0 q/ha when sown with optimum seed rate (30 kg/ha) and spacing (25 cm x 10 cm) in moisture retentive rice follows.
  12. Among maize based intercropping systems, Maize + Arhar(2:1) and Maize + Groundnut(2:3) in a paired row planting pattern(30-120-30 cm)gave a combined maize equivalent yield of 49.9 and 46.3 q/ha for the corresponding systems, yielding a net profit of Rs.14,156.00 and Rs.13,393.00, respectively.
