Research Accomplishment :

Drip irrigation and Fertigation in different crops

  • In sugarcane (C0 7219) drip irrigation at 2days interval saved 43.2% water with 19.7% more cane yield as compared to surface irrigation. Application of water-soluble fertilizer with three major plant nutrients through drip in twenty times out yielded urea application alone.
  • In tomato drip irrigation at 2 days interval produced 8.1% higher fruit yield with 33.4% saving of water over surface method when irrigation was applied at 60 mm CPE.
  • In tomato f ertigation of 58 kg/ha N in ten splits at 7 day interval with 31% during vegetative and 69% during reproductive and fruiting stage produced 41.0 t/ha fruit yield and saved 27.5% nitrogen as compared to 80 kg N/ha applied in equal splits in which fruit yield was slightly higher (43.8 t/ha) but saved 28.5 % nitrogen.
  • In pointed gourd irrigation applied at 80% PE saved water by 18.6% and enhanced irrigation water use efficiency by 16.3% over 100% PE. Fertigation with 75% of the recommended dose (180:90:90 kg N, P 2 O 5 and K 2 O /ha respectively) in 8 equal splits produced maximum fruit yield of 5.46 t/ha with net saving of 25% fertilizer dose.
  • In bitter gourd , irrigations applied at two days interval through drip @100% PE produced maximum yield of 5.72 t/ha and saved 24.2 % irrigation water over surface irrigation methods at IW/CPE 1.20 .
  • In case of Brinjal and Capsicum, irrigations provided through drip @80% PE at 2days interval produced slightly higher fruit field i.e3.2 and 5.9% but saved 41and 37% irrigation water over surface irrigation.
  • In Aswagandha ; Irrigation at 80 % PE through drip has proved better than 100 and 60 %PE.
  • In Stevia and Mint: Irrigation at 100 % PE through drip has proved better than 80 and 60 %PE.
  • Intercropping of ginger and turmeric in between two rows of banana irrigated through drip produced additional income without further investment of drip system. So in wider spaced row crops intercropping should be followed wherever feasible.

Micro- Irrigation status in India from AICRP on WM : Worked in Coordinating unit of AUICRP on Water Management and assisted Project Coordinator in terms of technical matter with respect to pressurized irrigation systems , and salient achievement are reflected in the following text.

  • Pressurize irrigation with fertigation : At Rahuri in Maharashtra sugarcane yield of 146.4 t/ha (19.9% higher yield) with 29.5% saving of water was recorded when irrigation was provided through drip at 2 days interval as against surface irrigation at 75 mm CPE (IW=6 cm) in which the cane yield was 122.11 t/ha and water applied was 231 cm. Among with irrigation in drip system application of required amount of fertilizer is highly beneficial. The results showed that application of nitrogen in 20 splits at weekly interval up to six months crop age produced 172.51 t/ha in four row planting pattern followed by 171.11 t /ha in two row plantings. In case of furrow irrigation when four splits of nitrogen was applied, the cane yield was only 138.0 t/ha. Saving of water in four and two rows of planting was 54.5 and 48.7%, respectively over furrow method in which the amount of water applied was 198 cm. At Navsari (Gujrat) sugarcane yield in drip method on alternate day irrigation was 7.3% higher with 42.5% saving of water than furrow method of irrigation wherein irrigation was applied at IW/CPE 0.75.
  • The importance of pressurized irrigation system on horticultural fruit crops, vegetable crop, has been synthesized from AICRP on WM centres and showed substantial saving of irrigation water .

Rain water harvesting and use during rabi \ summer season

  • The runoff recycling system was evaluated for multiple use of runoff water through ponds. The B:C ratio with crop alone was 1.89. When horticultural crops and fisheries production was taken then the B: C ratio went up to 2.27 and 2.80, respectively. Due to high income generating technology, this system was implemented in I)TIFAC project, ii)AGRAGAME(NGO),in consultancy mode, iii) MoU signed with XIM, Bhubaneshwar

Water requirement in Medicinal plant

  • Coleus ;Coleus forskolii is high value medicinal plant, Its ingredients .Forskolin is powerful medicine . Control heart failure, glaucoma, and broanchial asthama. It lowers blood pressure, it improve circulation of blood to the brain. Optimization of crop geometry has been done and found that 75x 45 cm crop geometry gives better performance. This can be fitted in to rice based cropping system as well as drip irrigation when it is grown during rabi season

Conjunctive use of water:

  • Due to non availability of canal water in proper time in middle and tail reach, the provision was made to exploit ground water through bore wells and open well on participatory mode by involving 23 farmers in first year and 54 farmers in second year. Instead of taking one crop, they have taken two and three crops in a year with rice-groundnut, rice-wheat and rice- potato-sunflower. The increased their rabi and summer crop yield substantially with 200-300 % cropping intensity.
  • In canal command area , seepage loss is very high and it goes in to drainage nala, if this return flow is pumped and used during rabi and summer season, the cropping intensity is increased. In Chaukinala watershed (28,000 ha) in Hirakud command, the study was made to measure irrigation return flow, water quality, water table fluctuations etc. The water quality of return flow was good; ground water table was also at shallow depth during rabi season. The tail end farmer can manually lift the shallow water of open well and irrigate their rabi crop without much difficulty.
  • Canal command area particularly in tail reach, creation of auxiliary storage tank help the farmers to store canal water during canal on period and use during canal off period. At WTCER research Farm near minor irrigation storage tank has been created as model for other irrigation. Study was made to evaluate irrigation efficiency of the system i.e pressurized with surface irrigation with different vegetable, flower and horticultural fruit crop on embankment of the ponds. The system performed well and increase overall income of the system by cultivation of additional rabi and horticultural crops and fish in ponds.
  • Conjunctive use of bad and good quality water in a specified proportion can helps the farmers to harvest crop yield to some degree of crop yield. Use of Emami paper mill sludge with good quality water in ground nut and maize produced good yield in acid soils of Balasore (Orissa) districts . As in eastern region substantial acid soil is available which needs immediate reclamation process. In Sakti Sugar Industries, Dhenkanal (Orissa) sugar effluents with different proportion has been used in ground nut and sugarcane and sugar beet during rabi 2005-06 and very good response with respect to crop growth and yield has been achieved.

  Ground Water Resources appraisal

  • Resources appraisal of eastern states revealed that the eastern states is rich in water and soil resources, however the utilization is very low due to several constraints. The ground water development in eastern part is very low ( Orissa 18.71%, West Bengal 32. 99 %, Bihar 35.99 %, Jharkhand 21.64%, Chhattisgarh 21.4% Tripura 33.43%, Assam 7.46%) , which is far below than the national average. So further exploitation of ground water in this region is quite essential to increase cropping intensity to the extent of 200 to 300%.

Water Resources development and utilization

  • Under TIFAC project, water resources has been developed in five villages in Odegaon block of Nayagarh district and farmers are growing rabi as well as summer season, Due to water resources structures the farmers are also using harvested rain water during dry spell period. So the cropping intensity has gone more than 200 %. (Detail result is available in DST –TIFAC website /autoinst/tifac.htm).
  • In Keonjhar district also, water resources has been created by constructing series of 8 open well along the drainage nala as well as small bund across nala. The embankment across the nala is acting to recharge ground water The farmers are pumping the recharge water for irrigation during rabi season. In this way they are harvesting good yield of rabi crop. The cropping intensity has gone up to 132% with good yield in both season crops
