This study assessed the influence of promotional methods on the adoption of improved rice varieties in Wadelai Subcounty, Pakwach district. It specifically aimed to assess the knowledge gap of farmers on improved rice variety production, to evaluate the influence of promotional methods on the adoption of improved rice varieties and to examine the agronomic practices employed by the farmers for improved rice varieties. A sample size of 94 respondents including rice farmers and key informants was used. Data was collected with the aid of questionnaires and interviews. Data was analysed using SPSS version 23 statistical tool. The study established that rice production in Wadelai subcounty was largely caried out by females, married, relatively large households, less educated farmers who engaged in farming and fishing with less experience (<5 years). SUPER (64.8%), NAMUCE (42.9%) and NERICA (48.4%) were improved rice varieties cultivated while Sidani (14.3%) was the least produced local variety. Production was relative at an average of 4.2 acres with farmers producing more than one rice variety at the same time. Specifically, the rice farmers experienced knowledge gaps in soil and water conservation (83.5%), pest management (81.3%), seed bed preparation (76.9%), planting methods 975.8%), management of invasive weed species such as striga (72.5%) and physiological properties of matured rice (60.4%). The study determined that promotional methods including; trainings, demonstrations, farmer filed visits, radio talk shows and price discounts were significantly(p<0.05) associated with complete adoption of improved rice varieties for farmers who adequately participated in them and partial adoption among farmers who had moderate engagement. Agronomic practices; pests and disease management (86.8%), proper tillage (81.3%), timely planting (75.8%), timely weeding (74.7%), harvesting (65.9%) were largely practiced in the production of improved rice varieties however, there was reluctance in using new rice seeds in every planting (47.3%) and fertilisers (15.4%) in production. It can be concluded that adoption of improved rice varieties was high, this was because the promotional methods used were effective in influencing complete and partial adoption. Subsequently farmers followed most of the recommended agronomic practices however, recycling of the improved seeds and non-utilisation of fertilisers in improved rice production was a hinderance for optimum rice performance. Farmers in Wadelai subcounty need to be trained on better agronomic practices in production of improved rice varieties.

An experiment was set up in Kapir sub-county, Ngora district to evaluate the effect of Bradyrhizobium Mak-biofixer inoculum on seedling vigor, seed germination and nodulation ability of NAROGRAM 2 variety. A completely randomized block design was set up to evaluate different nodulation attributes including; nodule color, nodule number and nodule position from the second week of seedling emergence till the sixth week of seedling emergence. Two treatments were used for this study (10g of inoculum/1000g of seeds and 12g of inoculum/1000g of seeds) and the control involved the seeds which were not inoculated with the rhizobium. The field experiment had twelve replicates in total. Another experiment in a screen house was set up following a completely randomized design. Two treatments (10g of inoculum/1000g of seeds and 12g of inoculum/1000g of seeds) and the control involved the seeds which were not inoculated with the rhizobium were used. The screen house experiment had twelve replicates/petri-dishes in total. Data on seed germination was collected on 100 seeds for 30 days. Data on seedling vigor (root and shoot length) were collected on ten plants per petri-dish for 3 days, 6 days and 9 days after germination. The treatment of 12g of inoculum/1000g of seeds had a higher seed germinability than a treatment of 10g of inoculum/1000g of seeds. On the 9th day of germination, the treatment of 12g of inoculum/1000g of seeds had the non-significantly (P˃0.05) longer root and shoot length compared to a treatment of 10g of inoculum/1000g of seeds. Application of different treatments of rhizobium inoculation had varying effects on nodulation of NAROGRAM 2. In the 4th week of data collection, the treatment of 12g of inoculum/1000g of seeds had a non-significantly (P˃0.05) higher value of nodule color score, nodule number and nodule position scores relative to the treatment of 10g of inoculum/1000g of seeds. The rhizobium application of 12g of inoculum/1000g of seeds had higher seed germination and seedling vigor therefore, enhances rapid field seedling emergence and establishment which in turn result in higher yields. Application of 12g of inoculum/1000g of seeds had higher nodule color compared to 10g of inoculum/1000g of seeds implying more effective nitrogen fixation. Furthermore, the application of 12g of inoculum/1000g of seeds had higher nodule number and nodule position score implying presence of both lateral and crown nodules which enhances efficient nitrogen fixation.

This book is the result of twenty years of puzzle collecting. For these many years I have endeavored to gather everything belonging to the realm of mathematical entertainment from all available sources. As an editor of newspaper columns on scientific entertainment, I found my readers keenly interested in this kind of pastime, and these readers proved to be among my best sources for all sorts of problems, both elementary and intricate. Puzzles seem to have beguiled men in every civilization, and the staples of scientific entertainment are certain historic problems which have perplexed and diverted men for centuries. Besides a number of these, this book contains many problems never before published. Indeed, the majority of the problems have been devised by me or have been developed out of suggestions from readers or friends. This book represents only a relatively small selection from an inexhaustible reservoir of material. Its purpose is to satisfy not only mathematically educated and gifted readers but also those who are on less good terms with mathematics but consider cudgeling their brains a useful pastime. Many puzzles are therefore included, especially in the first chapters, which do not require even a pencil for their solution, let alone algebraic formulas. The majority of the problems chosen, however, will appeal to the puzzle lover who has not yet forgotten the elements of arithmetic he learned in high school. And finally, those who really enjoy the beauties of mathematics will find plenty of problems to rack their brains and test their knowledge and ingenuity in such chapters as, for example, "Whimsical Numbers" and "Playing with Squares" The puzzles in this book are classified into groups so that the reader with pronounced tastes may easily find his meat.

Cornerstone is a proposed company that shall provide services for concrete fabrication, utilizing formwork, laying foundations, concrete placement, and excavation. The company has worked on several projects in the Norman and Southwestern Oklahoma areas, and plans to bid on contracts for commercial concrete projects at all levels throughout the state. The company plans to develop into the leading formwork-services provider for reinforced concrete in the state. This means always having the best and most efficient facilities, processes, and people. To achieve this, Concrete Fabricators will invest in ways that will pay off in competitive advantages for its customers, such as structural plan review, including pre-job conferencing upon request, equipment, and a full line of forming, reinforcing, and aftermarket products. The company has developed a client evaluation form to gather feedback from our clients. The ultimate goal is to meet these needs and better the company. The biggest concern within the concrete work industry is the health and safety of its employees. Concrete Fabricators has made safety its number one concern; our employees and our customers expect to be safe on the job. The company has recognized the need to keep taking steps to develop a comprehensive infrastructure designed to make us not just a company with a safety policy, but a “safe company.” Concrete fabricators participate in the concrete work industry.
