Abstract
Field experiments were conducted during the kharif season of 2006 and
2007 at Tamil Nadu Agricultural University, Coimbatore. The main plot treatments
comprised of two factors viz., crop geometry (60 x 20 cm and 75 x 16 cm) and
intercropping systems (baby corn alone, baby corn + fenugreek (greens), baby corn
+ fodder cowpea). Four topping practices (detasseling alone, topping beyond 9th internode,
topping beyond 10th internode and topping beyond 11th internode) were assigned to
sub plots. Baby corn raised at 75 x 16 cm produced higher yield parameters and
yield over 60 x 20 cm spacing. Intercropping of fenugreek and fodder cowpea did
not reduce the yield of baby corn. Topping beyond 10th internode favourably influenced
the yield parameters viz., length, diameter of cobs and corns and green cob yield
of baby corn.
Keywords: Baby corn, crop geometry, intercropping systems, topping practices, yield
