The present investigation was carried out during two successive seasons 2016/2017 and 2017/2018 to determine the impact of two growth regulators (IAA and IBA) either solely or in combination as well as studying the effect of offshoot weight on rooting of date palm offshoots Cv. Sakkouti. The best results concerning the number of roots, root dimeter, the length of longer roots and new leaves were resulted from treating offshoots by IAA or IBA each at 4000 ppm or in combination between them each at 2000 ppm. The highest weight of offshoots (8-10 kg) presented the best results concerning any investigated parameter.

Fungal and bacterial plant diseases cause major losses in agricultural activities and food production through damaging plants and/or crops. This study was conducted to evaluate the antagonistic effect of some fungal, bacterial and yeast biocontrol agents (BA) (Trichoderma harzianum, Pseudomonas fluorescens, mycorrhizae Glomus sp. and Saccharomyces serivisae ) and a mixture of them against damage of corn (Zea mays L.) caused by three isolates of Fusarium moniliforme. In the current experiment, significant reduction in the disease incidence such as number of infected plants and ears was observed in BA treatments in comparison with untreated control accompanied with enhancement of growth features such as plant height and weight, root length and weight and average weight of ears. The obtained results revealed that applying of Mycorrhizae Glomus sp. and Sacchromyces serivisae (Yeast) together showed significant superior effect to reduce diseases incidence and improving growth parameters followed by the BA mixture then Trichoderma harzianum and Pseudomonas fluorescens, respectively. Treatments increased peroxidase and polyphenol oxidase in corn leaves. Mycorrhizae was the most effective in this respect.

The study involved the recycling of gmelina fruit pulp to animal feed to reduce environmental pollution by evaluating the feed intake and body weight changes of rabbits fed diets incorporated with Ripe Gmelina Fruit Pulp (RGFP) at 0, 25, 50, 75 and 100% in replacement of maize as groups I, II, III, IV and V, respectively. Sixty (60) rabbits in five groups of 12 animals each were used for the eight-week study in completely randomized design experiment. Initial weight, final weight, weight gain, feed intake (concentrate + forage), concentrate intake and forage intake ranged from 575–575.02g, 1605–1900g, 1029.98–1324.99g, 8130–7569.85g, 5711.33–1177.11g, 6392.74–2418.67g, respectively. All these parameters were significantly affected (p<0.05) by inclusion of RGFP except initial weight. Feed conversion ratio (FCR), water intake (ml), water–feed ratio and protein efficiency ratio ranged from 7.35–6.14, 278.34–203.36, 0.034–0.027 and 0.8–0.53, respectively. These parameters were also significantly affected (p<0.05) by inclusion of RGFP in diets except water–feed ratio and protein efficiency ratio. Weight gain, total feed intake (concentrate + forage), concentrate intake and water intake of rabbits fed 0% RGFP were the highest (p<0.05) while the 100% RGFP group recorded the least (p<0.05). Weight gain and total feed intake of 0% RGFP group was similar to those of groups 25%, and 50%. The 100% RGFP fed rabbits had the highest (p<0.05) forage intake but least (p<0.05) FCR while 0% RGFP fed group had the least (p<0.05) forage intake and highest (p<0.05) FCR. Weight gain, total feed intake (concentrate + forage), concentrate intake and water intake significantly (p<0.05) decreased as RGFP increased while FCR and forage intake increased significantly (p<0.05) as RGFP increased. This study suggests that RGFP could replace up to 50% of maize, beyond which the animals start losing weight. Keywords: Hindgut fermenter, Gmelina fruit waste, rabbit nutrition, recycling

Roots of orange fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and important remedy for vitamin A deficiency. The cream or white fleshed varieties on the other hand, have sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. The objectives of this study were to examine the quantitative inheritance of important traits in sweet potato by means of a diallel analysis with a view to estimating the GCA and SCA components of genetic variance, and to determine the associated type of gene action controlling β-carotene content and root dry mass. A diallel crosses experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out. Resultant thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria during the cropping season of 2012 and 2013. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for all the tested traits. The average β-carotene content for the progenies was 2.86 (mg/100 g f.w.) while the dry matter content was 31.89%. The cross combination 199024.2 x Excel recorded the highest beta carotene (14.37 mg/100 g f.w) and dry matter content (40.10%), this candidate is therefore suggested for further evaluation.

A study conducted for a period of fifty (50) days to determine the growth performance, carcass and organ weight of growing boars fed graded dietary levels of raw Icacinia manni tuber meal. Four experimental diets were formulated with Icacinia manni (Earth ball) replacing maize at 0, 5, 10 and 15% levels designated as T1(control), T2, T3 and T4, respectively. Forty-eight (48) young boars (Landrace x Large white) each weighed 7.72+ 0.35kg were assigned to the four dietary treatments and replicated three times of four boars each in a completely randomized design. Carcass traits and relative organs weights were evaluated. These traits were; dressed weight, dressing percentage, head, shank, trotter, belly, thick rib chop, rib chop, loin, chump chop, leg fillet end, Leg shank end, liver, lungs, kidney spleen and heart. The results indicated that apart from T4, diets T1, T2 and T3 did not differ significantly (P>0.05) in terms of feed intake, weight gain and feed conversion ratio. This implies that Icacinia manni did not affect growth performance except at 15% level of inclusion Similarly, Pigs fed diets T2 and T3 showed significant (P 0.05) across dietary treatments except the lungs in T4 (15%) signifying the non-deleterious effect of raw icacinia manni, at 10%. To attain optimum performance and carcass characteristics in young boars therefore, inclusion of raw Icacinia manni in young boars’ diet at 10 percent is recommended.

The storage of sweet potato tuberous roots in tropical countries is a major challenge to farmers and retailers due to unfavourable climatic conditions. In this study, the storage performance of sweet potato roots in an ambient condition was investigated over a 12-week duration. The three different pre-storage treatments used were ash, alkaline solution (1.5 mol dm-3) and Siam weed (Chromolaena odorata) extract – to evaluate their effects on weight loss, shrinkage, weevil damage and sprouting. The control comprised tubers with no pre-treatment. It was observed that weight loss increased linearly from the inception of storage while shrinkage became apparent only after two (2) weeks. The percentage shrinkage of the tuber pre-treated with Siam weed increased at decreasing rate from 8 WAP. Treatment of tuber with Siam weed extract provided significantly higher protection against weevil damage (p > 0.05). After this, sprouting was initiated. By the 12th week, the Siam weed (Chromolaena odorata) extract treatment yielded better results. The Siam weed (Chromolaena odorata) treatment also recorded the lowest weight loss of 28% and lowest shrinkage of 2.8%. It also sustained less weevil damage at 33.5% compared with the other treatments. Sprouting was higher in the tuber without pre-storage treatment. The alkaline solution and ash treatments had varied degree of performance for all the indicators. Keywords: Sweet potato storability, Ambient condition, Pre-storage treatment, Chromolaena odorata

The study assessed the marketing activities of ducks in Akinyele Local Government Area. The study was carried out in three selected main markets (Ojoo, Moniya, and Shasha). Information was generated from ninety-four (94) duck marketers in the study area using structured questionnaire to determine the socio-economic characteristics of duck sellers, profitability, market performance and problems militating against duck marketing. The data were analyzed using descriptive statistics, Gini coefficient, budgetary analysis and marketing margin. The result showed that 52.1% of respondents were males while about 47.9% of respondents were females. Age range of 40-50 (38.3%) is the majority which means that adult dominate the duck business. Majority of them are married (63.8%), with no formal education (31.9%) and with marketing experience (40.4%) of less than five years. The result of the Gini coefficient was 0.52 which implied that the degree of income inequalities is high in sales revenue of the respondents and hence high level of concentration. Moniya market is more efficient among the other market visited. Duck selling business in Moniya is more profitable as sellers on the average realized gross revenue of ₦280,700; followed by Ojoo, ₦147,582; and Shasha, ₦116,640. The problems encountered include, low patronage, low price, disease infestation, mortality and theft. It was recommended that there should be general awareness of the business as a means of employment which would serve as poverty alleviation in the society. Key words: Market structure, Market performance, Profitability, Ducks

The study investigated the media use preference among coconut farmers in the western zone of Lagos state, Nigeria. A total number of 120 coconut farmers were selected for the study. Data were collected with the use of interview schedule and analyzed with frequency count, percentage, mean and Chi-square statistics. The usage mean rank showed that mobile phone (mean=4.49), radio (mean=4.47) and television (mean=4.09) were ranked first, second and third respectively. The highest ranked preferred media were radio (mean=4.63), agricultural extension officers (mean=4.43) and fellow farmers (mean=4.36). Chi-square analysis showed that there was no significant relationship between the coconut farmers’ media preference and their socio-economic characteristics. The study conclude that mobile phone, radio and television are the most frequently used media by coconut farmers in the study area. The study further averred that coconut farmers preferred radio, agricultural extension officers, television, family and friends as a medium of communication. The government and non-governmental organizations should intensify the dissemination of information to the coconut farmers using media such as radio, agricultural extension officers, television since that is the most preferred media.
