EFFECTS OF NEEM SEED OIL SPRAY REGIMES ON CERCOSPORA LEAF SPOT DISEASE (Cercospora sesami Zimm) OF SESAME (Sesamum indicum L.) IN THE SUDAN SAVANNAH ZONE OF NIGERIA

Z. H. Mohammed, F. K. Mohammed

Abstract


Field trials were conducted in 2016 and 2017 cropping seasons at the University of Maiduguri Teaching and Research Farm to evaluate the effects of varieties of sesame (E8, NCRIBEN-01M, NCRIBEN-03L, NCRIBEN-04E and NCRIBEN-05E) and Emulsified neem seed oil (ENSO) spray regimes (No spray, once at 3WAS, twice at 3 and 5WAS and thrice at 3, 5 and 7WAS) to control Cercospora leaf spot disease on sesame. Sesame varieties were the vertical factors, spray regimes were the horizontal factors. Data were collected on disease incidence and severity, number of capsules per stand, number of seeds per capsule, one thousand seed weight and seed yield per hectare. Analysis of variance was conducted to determine the significant difference among treatments. Sesame variety NCRIBEN-05E sprayed thrice had significantly (p<0.05) lower percentage disease incidence and  severity. However, NCRIBEN-04E and E8 produced higher number of capsules per stand and higher  number of seeds per capsule and therefore more seed yield per hectare compared with the other varieties of sesame. ENSO at three spray regimes. The use of ENSO spray at three spray regimes and NCRIBEN-04E gave the best combination in terms of seed yield of sesame in both seasons and therefore could be recommended to farmers in the Sudan savannah agroecology of Nigeria.
