The study analyzed the economic of rice production in Gassol local Government area of Taraba State. Data were collected using structured questionnaires administered to 140 respondents’ selected using multi-stage random sampling technique. The analytical tools employed were descriptive statistics and inferential statistics. The finding revealed that, majority (70%) of the respondents were male and married. Most (55%) of them were in their prime age and 62% had farming as a primary occupation. The gross margin per hectare of land was N72, 914.1655 implying that rice production is profitable in the study. Multiple regressions result revealed that, the Linear function gave the best fit, and was selected as the lead equation; farm size (X2 ), Seeds (X3 ), Hire labour (X6 ), agro-chemicals (X5 ) and Farming experience (X8 ) contributed significantly to rice farmers’ output in the study area. High cost of inputs, lack of contact with extension agents, poor storage facilities and high cost of transportation were the major production challenges. The study recommended among others; the creation of opportunities for enhanced farmers’ accessibility to inputs and as well extension agents should be giving incentive so that they can education farmers’ using different mass media communication strategies.
In the present investigation, in vitro propagation of Jatropha curcas L. was achieved employing nodal explants. Axillary shoot bud proliferation was best initiated on Murashige and Skoog’s (MS) medium supplemented with 20 μM N6-benzyl- adenine (BA) and 50 μ M adenine sulphate, in which cultures produced 8.2 ± 0.56 shoots per nodal explant with 3.0 cm length after 3-5 weeks. The rate of shoot multiplication was significantly enhanced after transfer to MS medium supplemented with 2.5 μ M 6-furfuryl amino purine (Kn), 0.5 μ M indole- 3-butyric acid (IBA) and 25 μ M adenine sulphate for 4 weeks. Internode explant segments of Jatropha curcas plants responded in vitro and formed callus tissue when cultured on Murashige-Skoog (MS) full strength nutrient medium supplemented with 2,4-Dichlorophenoxyacetic acid (2,4-D – 4 mg/L) and N6-Benzyl adenine (BA- 4 mg/L). The internode-derived callus tissues were found non-embryogenic and hence did not regenerate into shoot and root, respectively. The internode segments when cultured on MS (full strength) media supplemented with BA – 5 mg/L) were found to grow forming two to three buds. However, these shooting explants did not form roots upon hormonal regulation. On the contrary, endosperm tissue cultured on full strength MS media supplemented with 3 mg/L BA and 1 mg/L Indole-3-butyric acid (IBA) along with activated charcoal (100 mg/L) and ascorbic acid (50 mg/L) yielded simultaneous shooting and rooting response after four weeks of incubation.
