Drip Tandojam

Research and Experimental Farm

The DRIP has established a research farm on 25 acres of land which is located at Tando Jam; about 18 kilometers in the east of Hyderabad. The DRIP research farm has mild weather and low rainfall. The source of irrigation is skimming well and canal. A single bore skimming well at DRIP Campus has been installed. The tapped water is used for irrigation of the experimental crops, as well as serves the drinking needs of the staff colony and office block. Twenty three piezometers have been installed at different depths and locations to monitor hydraulic gradient, radius of influence and the groundwater quality etc. The farm has a piped irrigation network and lined watercourses. Irrigation techniques such as trickle and sprinkler, bed and furrow, basin and flood are being evaluated on wheat, cotton, sugarcane, mango, ber, lemon and guava.

Lysimeter Station

The DRIP Campus has a state of the art lysimeter research station which was made leakage proof by bitumen coating. It consists of 12 conventional type lysimeters, each measuring 3 m x 3 m x 5 m. and provided with filter screens, non calcareous spawls and graded gravel filter material, drainage outlet and water feeding arrangements. For the artificial maintenance of different water table depths, Mariotte graduated bottles are used on all the lysimeters. To ascertain the desired watertable depths, each lysimeter is provided with a pressure meter and a manometer for counter check of watertable depths. The drainage effluent is collected in containers for measurement.

Agro Meteorological Station

An agro-meteorological station was established in March 1986 at the Institute. Meteorological parameters such as minimum and maximum temperature, relative humidity, pan-evaporation, wind velocity, wind direction, sunshine hours, precipitation, wet and dry bulb temperatures etc. are recorded and compiled on regular basis. Potential or reference evapotranspiration (ETP) are calculated on daily and hourly basis using Modified Penman equation.

Activities at Research and Demonstration Centre, Mithi, Thar

  1. 1 No. Deep tube well installed
  2. 1 No. rainwater harvesting pond constructed
  3. High efficiency irrigation systems installed on 16 acres
Research Activities at Farmers/ Community Lands
  1. 7 Nos. rainwater harvesting ponds (200'x200'x20') constructed
  2. 1 No. check structure/ retention dam constructed
  3. High efficiency irrigation systems installed on 16 acres
Objectives
  1. To confirm the consumptive use of water or actual water requirement for papaya.
  2. To establish crop coefficient and crop coefficient curves for papaya crop using empirical formulae or modified penmen equation.
  3. Assessment of soil salinity under different watertable depths.

Treatment

T1 = 1.50 m (from ground surface)
T2 = 2.00 m (from ground surface)
T3 = 2.50 m (from ground surface)

Methodology

"Determination of consumptive use of water for papaya plant under different watertable depths" started in the lysimeter May, 2013. There are two soil series namely Sultanpur Silt Loam (Medium Texture) and Miani silty clay loam (Moderately fine texture) which are filled each in six lysimeters. Thus the total numbers of lysimeters are 12. Each watertable is replicated four times twice in each soil series. The watertable depths are kept at 1.5 m, 2.0 m and 2.5 m from ground surface.

The papaya plants were planted in May, 2013. The pits were prepared about 30 x 30 x 30 cm. The distances between plant to plant and row to row were kept as 6 ft. Four numbers of plants were planted in each lysimeter. Soaking dose of 3 inches (708) liters was applied and remaining 6 irrigations of 2 inches were applied. Total 381 mm irrigation was applied during the period. Recommended dose of N.P fertilizer was applied and all the cultural practices are being carried out.
