NICRA Village: Muthukrishnapuram, Thoothukkudi district, Tamil Nadu

Rainfall Situation and Type of Contingency (Delayed onset of monsoon) : In 2012, the onset of north-east monsoon was delayed  i.e. second fortnight of October

Contingency Plan Implemented: In the village, due to delayed onset of monsoon, as contingency crops, maize, sorghum, pearlmillet and pulses were sown during 15th to 30th October.

            During crop growing season, only 97.7 mm was received (76.6 mm from seedling to vegetative stage), (12.1 mm flowering to grain filling) and  (9.1 mm grain filling to harvesting stage).

DSC06631Performance: Pearlmillet performed better while maize, sorghum and pulses failed. Pearlmillet gave a grain yield of 2300 kg/ha with income of Rs 8,500/ha (Fig..)

NICRA Village: Nakkalamuthanpatti, Thoothukkudi  District, Tamil Nadu

Rainfall Situation and Type of Contingency (Mid-season Drought) :  The village received 503 mm which was 26 % excess compared to the normal ( 399 mm ). There were  dry spells during 41st and 52nd SMW in 2011 and 1st  to 13th  SMW in 2012

Normal and actual (2011) monthly rainfall at Nakkalamuthanpatti Village

Contingency Plan Implemented: The cotton crop experienced dry spells during 41st (8th – 14th October) and 52 nd SMW (24th – 31st  December) in 2011 and 1st to 13th SMW in 2012 (except 6th and 11th SMW) which coincided with boll opening, ripening and maturity stages.  A supplemental irrigation of 5 cm from farm pond was given during these stages.

Performance: The supplemental irrigation mitigated dry spells during flowering and reproductive stages in cotton and resulted in  increased seed cotton yield  by 18 % (1860 kg/ha) with a BC ratio of 1.88 and additional net returns  of Rs 8975  compared to no supplemental irrigation  (Table7).
