Realtime Contingency

NICRA Village: Warkhed, Akola District, Maharashtra

Rainfall Situation and Type of Contingency (Midseason Drought) : In 2011 in the  village,  a rainfall of 640 mm rainfall was received during kharif  which was deficit by 103.6mm compared to normal (743.6 mm) (Fig.) and the  deficit  was observed  during  June to September as a result cotton crop experienced dry spells during 38th and 39th  SMW (September).                                                                     

Normal and Actual (2011) monthly rainfall, Warkhed village

Contingency Plan  Implemented:  To mitigate the dry spells, a conservation furrow was opened across the slope after 30 DAS in cotton.

Performance: Opening conservation furrow across the slope after 30 DAS in cotton had   resulted in maintaining/enhancing soil moisture , better crop performance (Fig),  increase in seed cotton yield was  by  19 %, higher  RWUE (1.82 kg/ha-mm), additional net returns of  Rs. 10,753/ha with B:C ratio of 3.02   as compared to farmers' practice (without furrow opening) (Table) .
