Strike Mbulawa (2017). Accelerating Agricultural Productivity to Enhance Economic Growth in Botswana. Current Research in Agricultural Sciences, 4(1): 14-31. DOI: 10.18488/journal.68.2017.41.14.31
The need to diversify the economy so as to ensure sustainable economic growth has been of great concern. Accelerating productivity in agriculture is seen as one of the alternatives to support the diversification initiatives by the government and drive growth in Botswana. This study discusses the factors contributing to increased long term agricultural productivity and hence its subsequent impact on growth in the short. The study employs the vector error correction model and annual data to explain the connection between key variables. This paper concludes that there is unidirectional causality from agricultural productivity to growth. This study shows that economic growth can be improved in the short term by improvements in agricultural productivity. Agricultural productivity can be enhanced by providing adequate infrastructure, additional farming machinery per hectare of arable land and having a targeted approach in the provision of funding towards agricultural oriented initiatives.

Contribution/ Originality
This study’s primary contribution is the finding that the agricultural led growth hypothesis applies to Botswana. The study is one of the few that use the vector error correction model to analyze the determinants of long term agricultural productivity.

One of the consequences of intensive floating net cage fish farming is that it needs large amounts of manufactured feeds for the consumption of all the primary freshwater species reared. However, in trophic-level-based fish cultures, the population of fish that feed on plankton, periphyton, and detritus is larger than that of high-trophic-level carnivorous fish. This research aims to discover the ability of barb (Osteochilus hasselti) as a water purifier biological agent in Cirata Reservoir by find the Average daily Gains of the fish, Efficiency and Cost Reduction in production. The experiment ranges from September to November 2014 at Cirata Reservoir’s Floating Net Cage, starting by acknowledging the genus and the number of periphyton from week 1 to week 6. To analyze Growth Rate (GR),  a Complete Randomized Design is used by applying five treatments, namely Treatment A: not fed (control), Treatment B: feeding level 1% of the fish’s weight, Treatment C: feeding level 2%, Treatment D: feeding level 3%, and Treatment E: feeding level 4%. The data are then collected in Variant Analysis; if a significant difference is found, it is proceeded to F Duncan Test. The economic parameter are Efficiency and Cost Reduction in production. The results show that there are 20 kinds of periphyton from phytoplankton genus. Twenty types of periphyton of the phytoplankton were of Bacilloriophyceae, Chlorophyceae, and Cyanophiceae classes. As for periphyton of the zooplankton genera, it consisted of Euglenoidea, Rhizopoda, and Rotifer classes. The number of periphyton is not different among the treatments, the GR is not significantly different for every treatment. We found that increased efficiency in the treatment of A (not feed) and decreased production costs as 3 %.

Contribution/ Originality
The paper's primary contribution is finding that there are Economic Efficiency and Cost Reduction at Net Cage which Monosex Barb (Osteochilus Hasselti ) Cultured With Reduction Feed in Cirata Reservoir.

Technical efficiency of resource use is imperative for increased rice production in Nigeria. The study attempted to determine the technical efficiency of swamp rice farmers in Ebonyi south  agricultural zone, Ebonyi state, Nigeria. Specifically, the study analyzed the socio-economic characteristics of the swamp rice farmers, determined the technical efficiency of the swamp rice farmers as well as the distribution of technical efficiency among swamp rice farmers in the study area. Purposive and random sampling technique were used to select sixty respondents for the study. Structured questionnaire was the instrument of data collection. Data collected were analyzed using descriptive statistics and stochastic production frontier. Results showed that the swamp rice farmers were in their active age (47years), predominantly male (70%), had average education (8 years spent in school) and married (86.7%). The maximum likelihood estimates showed that the variables of farm size, seed and labour were determinants of technical efficiency. The mean level of technical efficiency was 75.9% suggesting that an estimated 24.1% of the output is lost due to technical inefficiency in swamp rice production.

Contribution/ Originality
This study contributes in the existing literature on technical efficiency of Swamp Rice Farmers in Nigeria. The paper’s primary contribution is finding that the mean level of technical efficiency was 75.9% suggesting that an estimated 24.1% of the output is lost due to technical inefficiency in swamp rice production.
