Growth, Yield and Nutrient Use Efficiency of Corchorus olitorius under Irrigated and Rain-fed Conditions in Northeastern Benin (West Africa)

Abstract: Aims: Investigated the influence of organic manures (municipal solid waste compost [MSWC] and cow dung) and N-fertilizer on growth, yield and nutrient use efficiency of jute mallow (Corchorus olitorius L.) under two water regimes (rain-fed and irrigated). Original Research Article Katé et al.; AJAHR, 5(3): 32-44, 2020; Article no.AJAHR.55173 33 Study Design: Randomized complete block. Place and Duration of Study: Farm of Faculty of Agricultural Sciences, University of Parakou, Northern Benin (latitude 09°20’16.8’’N and longitude 002°38’54’’ E, 353 m asl), during 2013 rainy (June to August) and dry seasons (October to December 2013). Methodology: Ten treatments derived from a factorial combination of five levels of organic manures (control, MSWC at 10 t/ha, MSWC at 20 t/ha, cow dung at 10 t/ha and cow dung at 20 t/ha) and two levels of N-fertilizer (0 kg and 50 kg urea/ha), arranged in a randomized complete block with three replicates were considered. Results: Results showed that water regime significantly (p<.001) affected growth and yield of jute mallow. In addition, the growth and yield parameters showed significant differences (p<.001) in relation to different rates of organic manures. The integrated use of organic manure and urea increased plant height, number of leaves, stem diameter, number of branches, leaf growth parameters and leaf yield. The maximum amount of leaf yield (7554.88 kg/ha) was obtained with 20 tons/ha of MSWC and 50 kg urea/ha. Conclusion: Fertilizer types also had highly significant effects on nutrient use efficiency. Application of these treatments could help to enhance yield and growth of the jute mallow.

Influences of Seeding Dates and Pinching Height on Tender Shoot Productivity of Moloheiya (Corchorus olitorius L.)

Abstract: This study was conducted to seek optimum sowing time and pinching height for tender shoots production of moloheiya (Corchorus olitorius L.), which is a subtropical leaf vegetables, under an unheated greenhouse in the south of Korea. Seeds of moloheiya did not germinate at all at 10oC, but germinated well at 18~30oC with 95.5~98.5% germination rate. Germination rate was 75.0% at 15oC, but germination speed was very low. The pods of moloheiya sown before April 28 was matured after late-August, but those sown after May 7 was not matured in that year. In tender shoot production and harvest frequency, treatment sown on April 14 was most plentiful among sowing time treatments, and showed marketable yield increase by 14~42% compared to other sowing times. Meanwhile, pinching at 100cm high from soil surface was more effective than other heights for increment of branches and tender shoot. All above suggest that it was suitable to sow seed on mid-April and to pinch at 100cm high from soil surface for increment of tender shoots in the south of Korea.

Core collection of two important indigenous vegetables; Gboma eggplant (Solanum macrocarpon L.) and jute mallow (Corchorus olitorius L.) in Africa: an important step for exploitation of existing germplasm and development of improved cultivars.

Abstract: Gboma eggplant (Solanum macrocarpon L.) and jute mallow (Corchorus olitorius L.) are important indigenous vegetables of Africa. Even though these two indigenous vegetables are important in terms of nutrition, medicine and resilience of livelihoods, they have been neglected by scientific research and their value chain has not been developed. To ensure effective management and utilization of these important genetic resources in breeding programmes, it is important to collect their core collections. Therefore, eighteen different accessions of gboma eggplant and one hundred and six accessions of jute mallow were evaluated using RCBD with three replications. Results revealed diversity and significant variation among the various agronomic traits of both jute mallow and gboma eggplant. Correlation analyses between morphological traits of both species revealed positive and negative relationships, indicating predictable success for eventual breeding activities. Principal component analyses revealed traits of agronomic importance such as plant height, leaf length and number of leaves per plant as the most important traits for the distinction and separation of Corchorus olitorius accessions. The leaf blade length, leaf blade width, fruit colour at ripeness, plant height and fruit length were the most important traits for the distinction and separation of Corchorus olitorius accessions. Furthermore, hierarchical cluster analysis grouped the accessions into distinct clusters and accessions from the same geographical origin were classified separately. Nineteen accessions and six accessions were selected to constitute core collections of one hundred and six and eighteen accessions of jute mallow and gboma eggplant, respectively. Examination of the phenotypic traits showed that the genetic variation expressed for each trait in the entire collection has been preserved in the core collection. Core collections of these indigenous vegetables have many potential uses for the development of improved cultivars and should increase the utilization of germplasms of these important indigenous vegetables of Africa.

Effect of Storage Method on Nutrients Composition, Antioxidant Content and Consumer Acceptability of Corchorus Olitorius

Abstract: Corchorus olitorious is a vegetable that is popularly consumed in West Africa. It is also known to be rich in nutrients. The effects of market storage methods of vegetables on nutrient composition, antioxidant contents and consumer acceptability of Corchorus olitorious were assessed at Owo, Ondo state, Southwest Nigeria. The vegetable was displayed inside a plastic basin and at 6 pm were sprinkled with water, placed inside polypropylene bag and left outside at room temperature of 27±1 o C. This process was carried out for 4 days. The colour and the taste of the vegetable (fresh and stored) were not significantly different (p>0.05) during the first two days of storage. Overall acceptability of Corchorus olitorius stored for four days by the panellist, ranked significantly (p 0.05) in the fresh Corchorus olitorius and those stored for two days. There was no significant (p>0.05) difference in the nutrient composition of Corchorus olitoriu s in the first two days of storage but reduced significantly (p 0.05). Corchorus olitorius had a scavenging ability of 0.05) as the storage period increased. These results show that based on the storage method available to the market women in the study area, Corchorus olitorius vegetable should be sold within the first two days of harvesting.
