This research was carried out using twenty five (25) mixed breed weaner rabbits to investigate the effect of replacing bone ash with fresh water snail (Pila ampullaceal) shell ash on the diet of weaner rabbits on the economics of production. Five experimental diets tagged T1 to T5 were formulated such that fresh water snail (Pila ampullaceal) shell ash replaced bone ash at 0%, 25%, 50%, 75% and 100% for treatments T1 to T5 respectively. The rabbits were randomly assigned to the five dietary treatments and replicated five times giving a total of one rabbit per replicate in a completely randomized design (CRD). The research showed that the diet affected the economics of production such that feeding dietary treatments resulted in positive profit per rabbit at 100% level of inclusion of the test ingredient. The cost of feed in gram of each treatment feed was lower in fresh water snail (Pila ampullacea ) shell ash based diet than the control diet. This research has shown that fresh water snail (Pila ampullacea) shell ash can serve as a substitute for bone ash in weaner rabbits diet up to 100% positively affected the economics of production parameters.

Seven hundred and twenty squabs raised from 180 couples of domestic pigeon were used to                 study the heritability, phenotypic and genetic correlations of body and egg traits. Body weight at hatch, 1- week, 2- weeks, 3- weeks, 4- weeks and at maturity were measured. Age at first egg               and weight of first egg were the egg traits considered. The mean mature bodyweight, Age at                first egg and weight of first egg were 416.39±1.77 g, 147.26±0.44 days and 18.06±0.10 g, respectively. Heritability estimates ranged from 0.24±0.03 to 0.57±0.07. Phenotypic and genetic correlations between bodyweights at different ages were positive and significant (P<0.05).                    It was concluded that the body and egg traits evaluated could be improved by mass selection method and any improvement in the bodyweight could lead to a concomitant increase in the associated trait.

The experiment was conducted during the period of March to August (Aus season), 2013 at the experimental farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, and Dhaka to evaluate the growth performance of some rice varieties in relation to their economic yield. The performance of BRRI hybrid dhan1, BRRI hybrid dhan2, ACI hybrid2, Jagoron and Panna1 were compared with check variety, BRRI dhan48. The experiment was laid out with Randomized Complete Block Design (RCBD) with three replications. Data were recorded on different growth parameters, grain yield, straw yield, biological yield and harvest index. The data were recorded at 30, 45, 60 and 75 days after transplanting (DAT) as well as at final harvest and obtained data were statistically analyzed for comparisons. In term of vegetative growth parameters, plant height, tiller hill-1, leaf area index, stem dry matter hill-1, leaves dry matter hill-1 and total dry matter hill-1 at different DAT, the ACI hybrid2 was superior over the check variety, BRRI dhan48 as well as BRRI hybrid dhan1 and BRRI hybrid dhan1. Highest and statistically significant grain yield (3.05 t ha-1) straw yield (4.20 t ha-1) biological yield (7.25 t ha-1) and harvest index (42.01%) was observed in ACI hybrid2 which was statistically identical with hybrid rice Jagoron and Panna. All test hybrid varieties were superior in vegetative and yield performance over inbreed BRRI dhan48 during Aus season.

The research was conducted using twenty five (25) mixed breed weaner rabbits to investigate the effect of replacing bone ash with fresh water snail (Pila ampullacea) shell ash on carcass parameters of weaner rabbits. Five experimental diets tagged T1 to T5 were formulated such that fresh water snail (Pila ampullacea) shell ash replaced bone ash at 0%%, 25%, 50%, 75% and 100% for treatments T1, T2, T3, T4, and T5 respectively. The rabbits were randomly assigned to the five dietary treatments and replicated five times giving a total of one rabbit per replicate in a completely randomized design (CRD). The treatments revealed a non- significant (P>0.05) effect on the dietary supplementation except for colon length. This study had shown that fresh water snail (Pila ampullacea) shell ash can serve as a substitute for bone ash in weaner rabbits diet up to 100% without adverse effect on the parameters determined.

Aims: Twenty accessions of sesame (Sesamum indicum) were screened for resistance to Cercospora leaf spot disease.

Sample: Twenty accessions of Sesamum indicum were used for the study. The sesame accessions were obtained from various localities and raised in a green house.

Study Design: Three to four seedlings were initially transplanted per hole and later thinned to two after establishment and arranged in a complete randomized design (CRD).

Place and Duration of Study: Cultivation of seedlings and transplantation were all carried out at a standard green house of the Molecular Biology Laboratory located at 124 MCC Road, Calabar, Cross River State of Nigeria in August, 2013.

Methodology: Isolation was made from leaves of diseased host plants. Test plants infected leaves with characteristic anthracnose symptoms were collected from the field. They were thereafter, subjected to pathogenicity test with Cercospora sesami to determine their levels of resistance to this debilitating pathogen.

Results: Plant height was strongly positively related to seed size (r = 0.85) and number of branches (r = 0.72) and had a significant correlation with the number of seeds per plant (r = 8.60). Correlation coefficient studies revealed that six out of the eight parameters were significantly (P = 0.05) correlated.

Conclusion: The results obtained indicate that accessions from Adagum and Ndok were immuned or highly resistant to Cercospora leaf spot (CLS) disease with disease severity of 0 (zero). Also, collections from Ogoja, Akim Market and Watt Market were resistant to CLS diseases with disease severity of 1.621, 1.820 and 1.545 respectively. Nwang, Mbube East, Bansara, Obudu Market, Obanliku Market, Gboko Market, Ukpa Market, Yahe Market and Ekpugrinya Market and Okpoma Market were either moderately susceptible or susceptible to CLS disease according to their mean disease severities.
