Indo-Dutch Network Project on Drainage and Water Management, Bapatla (1996-2003)

ObjectivesTo control salinity and waterlogging problems underNSP right canal command and Krishna Western DeltaNSP right canal command and Krishna Western Delta

ActivityDeveloped sub-surface drainage technologies Cl d b f t i t ll d i f 8Closed sub-surface systems were installed in areas of 8 ha and 7 ha with pipe spacing of 30 m, 60 m and 30, 45, 60 m at Konanki and Uppugunduru pilot areas respectivelyrespectively

OutcomeSoil salinity considerably reduced after introduction of

b f d i tsub-surface drainage systems

World Bank aided AP III irrigation project – SRSP & SRBC (1998-2004)SRBC (1998 2004)

ObjectivesApplied research and demonstrationApplied research and demonstration a) to improve irrigation practices and crop yields b) to promote high value horticulture crops c) Upgrading of agricultural extension servicesc) Upgrading of agricultural extension servicesActivity

Demonstrations were conducted on - irrigation methods and scheduling of irrigation for different crops - profitable crops and cropping systems- INM and IPM practicesConducted field days and trainings to the line department officials and farmersofficials and farmers

OutcomeEfficient use of canal waterIdentified efficient crops and cropping systems for canal p pp g ycommandsAwareness among the farmers in efficient utilization of water

Agricultural Research, Demonstration and Training under Tankfed Areas of Andhra Pradesh

(2003 2006)(2003-2006)

Objectives1 To demonstrate improved water management techniques1. To demonstrate improved water management techniques2. To develop optimal crop planning under limited water

availability 3. Conjunctive use of surface and ground water to improve the

t ffi iwater use efficiencyActivity

Demonstrated water saving technologies − irrigation at critical stages and rotational irrigationirrigation at critical stages and rotational irrigation

Successfully introduced ID crops − Kharif - maize, cotton, castor, bajra, greengram and green

i d d di imanuring crops and dry seeding rice − Rabi - vegetables and sunflower

OutcomeEfficient use of rain, surface and ground waterEfficient use of rain, surface and ground water Cropping intensity was increased >60% tank command area was brought under cultivation

AP Water Management ProjectImplementing in AP in collaboration with WUR, Netherlands

and monitoring by FAOand monitoring by FAO

Objectives:1. To enhance implementation of integrated water resources

management (IWRM)2. Improve the water use efficiency in agriculture3. Bring equity in water distribution in the command areas4. Promoting less water consuming technologies5. Capacity building to stake holders, line departments and

i tifi t ffscientific staff.Activity:

Demonstrated on pilot project mode in farmers fields of selected command areasselected command areas

to improve agricultural water management knowledge and empowerment of farmers’ organizations (WUA) to implement water management practices(WUA) to implement water management practices capacity building in IWRM.

Water Requirement of cultivars under aerobic and t l t d diti d i Kh if 2007transplanted conditions during Kharif 2007,

ANGRAU, Rajendranagar, Hyderabad

Salient observations:1. The available cultivars/varieties developed for transplanted andrainfed upland conditions and hybrids perform better both underp y paerobic (4.07-4.57 t/ha) and transplanted conditions (3.68-4.6 t/ha).Hence, there is a need to evaluate suitability of some of popularvarieties for aerobic condition.2. Around 200 mm of rainfall during kharif can be effectively utilizedfor rice production in aerobic rice.3. There was a saving of 31-37 percent of water under aerobic

diti d t t l t d diticondition as compared to transplanted condition4. The water productivity is higher in aerobic rice than that oftransplanted rice5 The aerobic rice can be successfully adopted in paddy grown areas5. The aerobic rice can be successfully adopted in paddy grown areasunder wells and canals by adopting proper varieties

Salient observations:

•The aerobic rice responds to applied nitrogen upto 150 Kg N/ha.•With increase in N levels, the water productivityWith increase in N levels, the water productivity increases.•All the varieties/cultivars responded similarly under aerobic conditionsaerobic conditions.•The grain yield was higher under aerobic condition than that under transplanted conditions•The response to applied nitrogen was higher in transplanted rice due to late planting than in aerobic rice
