This paper analyses the resource-productivity, technical efficiency (TE) and allocative efficiency of rain fed farmers in nigeria. The results of the parameters that enter the production function shows that herbicide has the highest elas-ticities, then seeds, followed by fertilizer and land while labour has the least contribution to output. Also, the result for the allocative efficiency based on the computed MVP x = P x show that none of the respondents optimally allocated the inputs. however, a greater number of the respondents were found to underutilized variables like land, seeds, fertilizer and herbici-de (MVP x < P x) while a greater number of the farmers over utilized labour (MVP x > P x). But in both cases, it was revealed that the use of more labour decreased the rice production from the study faster than any of the selected variables. The mean TE index was found to be 0.75. This suggests that 0.25 of rice yield is forgone due to inefficiency. The significant gamma (γ) value of 0.873 establishes the fact that a high level of technical inefficiency exists among the sampled farmers. Extension contact and access to credit are found to be significant determinants of TE among the farmers. hence, agricultural policy makers in nigeria should focus on how farmers could follow appropriate farm practices in the course of technology adoption to prevent under utilization of farm inputs via the intensification of extension activities in the country and accessibility to credit by farmers should be given more priority. Pursuing these will raise the productivity and efficiency of rice production in the country in the long run. Abstrakt: Příspěvek je zaměřen na analýzu produktivity zdrojů, technické efektivnosti (TE) a alokační efektivnosti pěs-titelů nezavlažované rýže v nigérii. Výsledky parametrů vstupujících do produkční funkce ukazují, že nejvyšší elasticita se projevuje u herbicidů, následně u osiv, hnojiv, půdy a práce s nejnižším příspěvkem k outputu. obdobně výsledky alokační efektivnosti založené na vztahu MVP x = P x ukazují, že žádný z respondentů nealokoval inputy optimálním způ-sobem, přičemž značný počet respondentů nevyužíval v dostatečné míře proměnné jako je půda, osiva, hnojiva a herbicidy (MVP x < P x) a současně velký počet farmářů nadměrně využíval vstupy práce (MVPx > Px). V obou případech však bylo zjištěno, že využití vyšších vstupů práce snižovalo produkci rýže ve sledovaných podnicích rychlejším tempem než v přípa-dě jakékoliv jiné zkoumané proměnné. Průměrná hodnota indexu TE byla 0,75. To naznačuje, že 0,25 potenciálního výnosu rýže je ztraceno díky neefektivnosti. hodnota významnosti gama (γ = 0,873) potvrzuje skutečnost, že mezi sledovanými farmáři převládá vysoká míra technické neefektivnosti. Poradenství a přístup k úvěrům byly shledány jako významné determinanty TE farmářů. z uvedených zjištění vyplývá, že tvůrci zemědělské politiky nigérie by se měli zaměřit na to, aby farmáři při implementaci technologií sledovali metody správného hospodaření, aby se tak předešlo nedostatečnému využívá...

This study was carried out to estimate the technical and economic efficiencies of poultry farmers in Imo State, Nigeria. The data was collected with semi-structured questionnaire from 140 randomly selected poultry farmers. A stochastic frontier production function was estimated by using the maximum likelihood estimation technique to obtain the technical and economic efficiencies of poultry farmers. The mean technical efficiency of poultry farmers was 75 percent, while their mean economic efficiency was 21 percent. The generalized likelihood test indicated that, the poultry farmers are not fully technically and economically efficient in resource use. There is 79% allowance to increase economic efficiency of poultry farmers by improvement in technical efficiency.

Profitability of rice production in different production systems in Ebonyi State, Nigeria was evaluated. Rice is critical for food security in Nigeria, hence, farmers need to make appropriate choices of rice production systems to optimize production and ensure an adequate domestic supply. This study used 2015 survey data from rice farming households. Rice farmers in swamp, lowland and upland rice production systems showed variability in profit. Swamp production systems had the highest return per hectare (29.37%) followed by lowland production systems (20.10%) and upland production systems (13.03%). Poor access to production credit and climate change were constraints to rice production in the area. Rice production using the swamp production system is profitable and would ensure increased production and higher returns to the farmers. It is recommended that farmers should form cooperative groups to enable them to pool resources together to boost their production.

Technical inefficiency among food crops farmers in Imo State was estimated using stochastic translog production frontier. The mean output of food crops farmers was 20.3 tons/ha, which is 9.6 tons/ha less than the expected food crops output of 30 tons/ha, and the mean level of technical inefficiency was 61.5 percent with a wide range from 21.24-98.13 percent. Major determinants of technical inefficiency were education, household size, farm size, access to credit, extension contact, farming experience and family labour use. There are still opportunities for increasing technical efficiency, productivity and farm income in food crops production in Imo state if these factors and given the desired attention.

Micro-level assessment of vulnerability to climate change creates basis for policy formulation. The study specifically ascertained the levels and determinants of vulnerability to climate change among selected food crop farmers. Data collected were analysed using descriptive statistics and ordinary least square regression analysis. The result revealed that 15.95%, 68.97% and 15.08% of the households were highly vulnerable, moderately vulnerable and less vulnerable to climate change respectively. This implies a varied effect on crop farmers. The result also showed that amount saved, extension contacts, household expenditure and value of crop were significant at 1% level. The study recommended the provision of basic amenities and soft loans to farmers as well as an improvement in extension services. It also advocated the introduction of effective climate change mitigation and adaptive measures to boost agricultural output in their area.
