The students of Sri Krishnadevaraya College of Horticulture Sciences in the district, using crop rotation method, have grown a crop of marigold flowers and are reaping good results.
On the same farm under a shade net, the students had previously grown solanaceous crops like tomato and cucumber but there were severe incidences of disease as well as soil-borne pathogens, especially nematodes(worms) affecting the crop.
To tackle this problem, the college dean had suggested adopting the crop rotation technique with marigold, and selected a new variety known as Arka Agni from the Indian Institute of Horticulture Research in Bangalore.
