After the blackgram cultivation failed to fetch lucrative returns, farmers in the Delta region switched over to gingelly cultivation anticipating a good profit. So, this year, they cultivated gingelly in an area of 1,450 ha against the usual 500 ha under chithirai pattom. Gingelly, a 90-day crop, could give yield between 200 and 300 kg per acre. Since it was sold at Rs 120 per kg last year, farmers were keen on cultivating the crop.
