The study investigated the growth and yield of cucumber cultivars under the influence of the organic fertilizers application.

A 4 x 5 factorial combination of four cucumber cultivars (Poinsett, Marketer, Marketmore, and  Darina hybrid) and four organic fertilizers (Sunshine, Aleshinloye, Gateway, KWASU organic-based fertilizer-KOBF, and the control) in a completely randomized design at the screen house and a randomized complete block in split-plot fashion in the field were replicated three times.

At 8 WAP in the screen house, the leaf areas and vine length at the control were significantly (p< 0.05) lower compared to the treated plots with the application of organic fertilizers. The  Darina hybrid had significantly longer fruit (17.8cm), thicker fruits (13.70 cm), and a higher Fruit yield per hectare (10083.23 kg) compared to other cultivars. In the field, regardless of the organic fertilizer applied, leaf area, fruit length, fruit circumference, and fruit yield per hectare produced at the control were significantly lower than where there were soil amendments. The treated plots with the application of KOBF had significantly more leaf area, longer and thicker fruits, and fruit yield per hectare compared to the application of other organic fertilizers. The fruit length (12.74 cm), fruit circumference (12.30 cm), and fruit yield per hectare (4048.29 kg) obtained with the application of Aleshinloye organic fertilizer were significantly (p< 0.05) lower compared to other organic fertilizers.

The  Darina hybrid was superior to other cultivars with the application of KOBF organic fertilizer.Highlights ·   The growth and fruit yield of cucumbers were enhanced with the application of organic fertilizers and varied among the fertilizers and cucumber cultivars. Regardless of cucumber cultivar, KOBF ranked first, followed by Gateway, Sunshine, and Aleshinloye.· Among the four cucumber cultivars, the darina hybrid was found to be the best in both the field and screen house studies.·  Application of KOBF fertilizer and Darina cultivars is recommended for organic cucumber production.

To evaluate the effect of palm bunch ash and mycorrhiza on soil properties and the performance of cucumber in Calabar.

Factorial combination of five levels of palm bunch ash – PBA (0, 3, 6, 9 and 12 t/ha) and two mycorrhiza treatments (inoculated and non-inoculated), laid out in randomized complete block design (RCBD) with three replications. Data were collected on crop growth and yield indices, soil properties (physical, chemical and biological) each year, then combined and analyzed. Duncan’s Multiple Range Test (DMRT) at 5% probability was used to compare the means.

There was increase in soil pH, organic carbon, phosphorus, potassium, calcium and magnesium as a result of PBA and mycorrhiza applications. PBA, mycorrhiza and their interactions significantly (p <.0. 05) influenced the vegetative growth and fruit yield of cucumber. Cucumber treated with 12 t/ha PBA had the highest vegetative growth and fruit yield values, which however were similar with those obtained from cucumber treated with 9 t/ha of PBA. Cucumber inoculated with mycorrhiza had superior growth and fruit yield than non-inoculated cucumber. The interaction of mycorrhiza and 12 t/ha PBA produced the highest values of vegetative growth and fruit yield indices, though similar with the interaction of mycorrhiza and 9 t/ha PBA.

Palm bunch ash was sufficient at 9 t/ha and is therefore recommended with mycorrhiza for effective soil nutrient enhancement and optimum cucumber production in Calabar.

This study evaluated the response of hot pepper (Capsicum annuum var. Red chili) towards cow vermicompost application under field conditions.

Cow vermicompost was supplied in four levels (0, 5, 10, and 15 t ha-1) across the two growing seasons in 2017 and 2018.

Vermicompost application significantly increased the plant height, internode distance, and the number of lateral branches in both seasons. It was noticed that manuring with 15 t ha-1 of cow vermicompost resulted with enhanced chlorophyll contents, fruit yield, and fruit number in both years. In both seasons, the highest leaf number, fruit weight, and total soluble solids are related to the third treatment (10 t ha-1 of cow vermicompost). The results showed that 1000-seed weight and vitamin C content were affected by cow vermicompost. Data showed that manuring with vermicompost (5 t ha-1) caused the best quality components in 2017 and 2018.

It was concluded that the application of vermicompost had a significant impact on vegetative and reproductive growth and fruit quality of hot pepper.
