Realtime Contingency(Centre:Arjia)

1.  NICRA Village:  Kochariya, Bhilwara District, Rajasthan

Rainfall Situation and Type of Contingency (Mid-season Drought) : In  2011, the  village received a rainfall of  ­­­­ 540.5 mm and there was a deficit of 117.2 mm compared to normal (657.7 mm). The onset of monsoon was normal. The crops experienced dry spells during third week of September onwards. Further, no rains were received during the post monsoon period against normal rainfall of 16.5 mm. The kharif crops experienced moisture stress during reproductive stages.

 

 

                                                                                           Normal and Actual (2012) monthly rainfall  at   Kochariya village

Contingency Plan Implemented: A supplemental irrigation from the stored rainwater in the farm pond was given to the vegetable crops.

Performance: The supplemental irrigation to vegetable crops resulted in higher pod equivalent yield upto 7083 kg/ha and water productivity, upto 1.58 kg/cu.m further by adoption of drip irrigation saved water up to 46 % as compared to surface irrigation. (Table)

2.  NICRA Villages:  Khalimati/Dholiya village, Banaskantha District and Chandank village, Mehsana District, Gujarat

Rainfall Situation and Type of Contingency (Excess rainfall and Midseason Drought) :The villages viz. Kalimati/ Dholiya and Chandanki received 1028.8 and 1110.3 mm, respectively  which were excess of 136.8 mm and 334.3 mm compared to normal 892 and 776 mm during kharif.                   Ccastor and cumin crops experienced moisture stress  during germination/ maturity stages.

Normal and Actual (2011) monthly rainfall in Kalimati  villages

Contingency Plan Implemented: The supplemental irrigation from the stored rainwater in the farm pond was given to castor and cumin at germination and reproductive stages.

Performance: The supplemental during dry spells resulted in better performance of  castor (GCH-7) and cumin (GC-4) (Fig)  Increased the yields by 41.7 % and 43.2 %, respectively with higher RWUE and BC ratio compared to no supplemental irrigation (Table).
