Cassava has gained prominence in the world and has become economic crop in the Nigerian agricultural sector. Secondary data was used for this study. The required variables were extracted from General Household Survey Panel Data (GHS-P). The GHS-P is a nationally representative survey of households across Nigeria covering urban and rural sectors. Analytical tools used included Total factor productivity and Markov chain. 82% of populations of Cassava farmers are in the rural areas and close to 73% were young adults including both male and female involved in cassava production. Approximately 65% of the cassava based farmers were single that not yet married and most of the farmers were educated and about 80% and 98% of the cassava based farmers did not have access to credit facilities and extension personnel respectively. Generally, the cassava productivity growth was erratic and very small proportion of cassava farmers that were in lower productivity reduced overtime, while the minimal proportion of cassava farmers that moved into both moderate and high productivity increased overtime respectively.  Generally, there is more to be done to increase and attain sustainable high level cassava productivity growth in Nigeria.

Nothing is more important than quality nutrition and adequate feeding of fish in captivity. Undernourished fish in terms of nutrient deficiency, cannot maintain its health for proportionate growth regardless the intense of feeding and quality of the environment. A 49 day-feeding trial was carried out to investigate nutritional quality differential, growth and economics efficiency of some sampled commercially extruded floating feeds, based on frequency of usage among fish farmers in the study area. The sample feeds were sourced from respective distributors covering the zone of study. The feeds were designated as Fd1, Fd2, Fd3, Fd4, Fd5 and Fd6(control), with 3 replicates for each treatment. The examined growth performance, feed utilization and economic efficiency of feeds followed particular trend pattern and significantly different (p<0.05) across the sampled feeds (FW, MWG, SGR, TPI, PER and FCR). Finally, the control diet was least consumed, sustained positive allometry growth pattern  and concomitant marginal profits; than feed 1 and 2 which had sharp drops in the growth pattern of fish after four( 4) weeks.
