Title of On farm Trial

Management of Fall Army worm Spodopterafrugiperda in maize.

2.

Problem diagnosed

Fall Army worm Spodopterafrugiperda is the most dreaded invasive insect pest associated with maize. It causes heavy losses up to 80 percent. Some times their infestation level is so high that farmers don’t get return even whatever they spend on seeds. Therefore it is needed for management of Fall Army worm.

Title of On farm Trial

Assessment and performance of plant growth regulator for synchronized flowering in pineapple (Var-Kew)

2.

Problem diagnosed

The pineapple requires higher cost of cultivation (Rs about one lakh per acre). Traditionally farmers use imbalanced and non-judicious use of hormones due to desynchronize flowering and low yield of pineapple.
