Abstract<br />
<strong>The</strong> study investigated the difference in productivity of small scale farmers that made use of organic<br />
fertilizer and otherwise in the study area. A total of a hundred and twenty(120) farmers were interviewed<br />
using simple random sampling technique. Sixty(60) copies of questionnaires were administered on each of<br />
organic and in-organic fertilizer small scale farmers. Descriptive Statistics(DS) was used to identify socioeconomic<br />
characteristics of respondents. <strong>The</strong> technical efficiency of individual farmers’ farm,<br />
determinants of the said efficiency and the level of productivity were the objectives upon which the<br />
research was launched to base the findings on. Stochastic Frontier Production Function(SPFS) was used to<br />
determine the impact of organic fertilizer or otherwise on efficiency frontier attained by each of the arable<br />
crop farmers under study. Also, Tobit regression model was used to identify the factors among factors<br />
responsible for the degree of efficiency score attained by each of the groups under study. <strong>The</strong> tested<br />
hypothesis revealed that organic fertilizer improves the efficiency and productivity of farmers<br />
tremendously at a very high significant level.<br />

Abstract<br />
Modified irrigation technique that poor resource farmers can afford and use easily is urgently needed in<br />
order to produce on a continuous basis to meet the demand of ever-increasing population globally.<br />
<strong>The</strong>refore, a field experiment was conducted at University of Ibadan, during the dry season in 2011 to<br />
evaluate the performance of organic okra under modified bucket kit-drip and watering-can methods of<br />
irrigation.<br />
<strong>The</strong> plots under bucket kit-drip irrigation system produced higher fresh fruit weight (88.9 kg ha -1 )<br />
compared to the watering-can system (77.8 kg ha -1 ). <strong>The</strong>re were significant differences in the mean values<br />
of 49.6 and 41.5, for number of leaves; 5.3 cm and 4.0 cm, for stem diameter; and 246.3 cm and 186.9 cm,<br />
for plant height under the drip and watering-can system respectively, with the drip system having higher<br />
values. Bucket kit-drip irrigation treatment had a higher mean percentage plant survival (88.9 %) than those<br />
under the watering-can method (86.7 %). <strong>The</strong> study showed that the drip system is more effective in<br />
making the environment suitable for plant survival that resulted to improved plant growth and yield.<br />
Key words: Bucket kit-drip irrigation, Watering-can irrigation, Okra yield<br />
