Abstract

Field trials were conducted at two locations in Samaru (110 11' N, 070 38' E and 686m above sea level) and Maigana (110 10' N, 070 37' E and 675m above sea level) both in Northern Guinea Savannah ecological zone of Nigeria during the 2018 wet season to determine the effects of three intra row spacing (40cm, 45cm and 50cm) on damage to cotton (SAMCOT 9) by bollworms. The experimental design was randomized complete block design. Data were recorded on the number of damaged shed squares, number of damaged shed cotton bolls and number of matured green bolls damaged by bollworms at two weeks interval beginning from 9WAS at the
different phenological stages until about 90% of bolls were open, which was a period of about 16WAS before the commencement of the first picking. Significant reduction in the number of shed cotton squares, shed cotton bolls and matured green bolls damaged by bollworms were observed on the 50cm and 45cm intra row spacings than the 40cm intra row spacing.
