“…While in 2018, the gross margin decreased by 16.9% in the 60cm x 30cm, 31.0% in the 60 cm x 40 cm plant spacing, 32.6% in the 70cm x 30cm plant spacing and 64.2% in the 70 cm x 40 cm plant spacing. Variation in gross margins due to plant spacing in okra has also been reported by the study [14]. The higher gross margin from the 50 cm x 40 cm plant spacing could be associated to the higher pod yield which contributed to higher revenue generated.…”

Okra is a very important vegetable in the field of nutrition and health care in Sierra Leone. The major limiting factors in okra production are incidence of insect pests and improper plant spacing. The present field research was undertaken at the Department of Crop Protection, School of Agriculture, Njala University to evaluate the effect of plant spacing on insect pest population, growth and yield, and profitability of okra production in Sierra Leone from 2017 to 2018 main cropping seasons. Five levels of plant spacing 50 cm × 40 cm (50,000 plants per hectare), 60 cm × 30 cm (55,556 plants per hectare), 60 cm × 40 cm (41,667 plants per hectare), 70 cm × 30 cm (47,619 plants per hectare), and 70 cm × 40 cm (35,714 plants per hectare) were adopted as treatments with three replications in randomized complete block design. The results of analysis of variance revealed that plant spacing were significant (P < 0.05) on insect population, plant height, leaf area, damage leaves, yield and yield components of okra at 4 and 8 weeks after planting (WAP) during 2017 and 2018 main cropping seasons. Okra cropped in plant spacing 50 cm x 40 cm (Recommended rate) inclined the highest number of insects, plant height, leaf area, damage leaves and yield at 4 and 8 WAP in both years followed by 60 cm x 40 cm plant spacing, while the reverse also holds true with 70 cm x 40 cm plant spacing. The profitability analysis revealed that the recommended plant spacing of okra (50 cm x 40 cm) produced the highest gross margins of Le 18,333,000.00 plants per hectare (ha-1) and Le 21,363,000 plants per hectare (ha-1) respectively during 2017 and 2018 main cropping seasons of okra production. In conclusion, increasing the plant spacing above the recommended plant spacing (50 cm x 40cm) could reduce insect population and leaf damage on okra, but will significantly decrease okra growth and yield, and profitability. Hence, in order to achieve maximum productivity of okra in the Njala area, the Clemson spineless variety of okra should be planted at a plant spacing of 50 cm x 40 cm. However, integrating plant spacing with other cultural methods of controlling insect pests of okra should be investigated in order to determine a sustainable and cost-effective method of controlling insect pests of okra.

“…Sampling began 45 DAP with the presence of flower visitors. As described by [33], the traps consisted of 16 oz squat polypropylene deli bowls (BioServ, Frenchtown, NJ, USA) painted with UV-bright fluorescent blue paint (blue trap) or yellow paint (yellow trap) and unpainted 12 oz white Styrofoam bowls (white trap) (Uline, Pleasant Prairie, WI, USA). The trap setup was carried out by gluing individual unpainted 16 oz polypropylene deli bowls onto a 36 plant prop and three of these were placed 0.2 m apart between the two rows of the PDC and cowpeas for each treatment for the entire sampling period.…”

“…For example, cowpea intercropped with corn [29], maize-cassava [30], and okra [31,32] resulted in increased crop yield compared to sole cropping. On the other hand, intercropping cowpea with tomato and okra resulted in a 45-55% loss in marketable fruit yields in both vegetables [33,34]. Most often, the ability of cowpea to fix atmospheric nitrogen and its contribution to the replenishment of soil fertility has been associated with the increase in crop yield [35].…”

Evaluation of Cowpea (Vigna unguiculata) in an Intercropping System as Pollinator Enhancer for Increased Crop Yield

Production of pollinator-dependent crops (PDCs) is increasing. However, pollinators are declining partly due to loss of floral resources. There is urgency to mitigate this decline and the potential risks to the production of PDCs and food security. One way is by promoting farming systems that enhance flower-rich habitats. In a two-year study, Pinkeye Purple Hull and Whippoorwill cowpea varieties attractive to pollinators were intercropped with three PDCs (squash, okra, and watermelon). We evaluated whether cowpea intercrop increases the abundance and diversity of pollinators, other beneficial insects, and crop yield, and decreases the abundance of the brown marmorated stink bug (BMSB). Diverse pollinators were recorded in both years for a total of 80,379, representing seven pollinator families (Andrenidae, Apidae, Crabronidae, Formicidae, Halictidae, Tachinidae, and Vespidae) captured in pan traps, six families (Apidae, Crabronidae, Halictidae, Pyralidae, Tachinidae, and Vespidae) from sticky traps, and five pollinator types (bumble bees, carpenter bees, honeybees, butterflies and moths, and wasps) through direct visual count. Pollinator abundance and diversity was highest on the cowpea-intercropped treatments than controls. PDCs intercropped with cowpea recorded more beneficial insects than BMSB. Okra, squash, and watermelon intercrops produced 7%, 27%, and 54% more fruits than the control, respectively. Our findings indicate that intercropping cowpeas with PDCs attracted more and diverse pollinators and resulted in increased crop yield. However, to optimize pollination, factors such as planting dates to synchronize the flowering of both cowpeas and PDCs should be taken into consideration.

“…However, growth and yield of okra depend on factors such as seed quality, soil nutrition, climatic condition and cultural practices as well as on the use of plant growth regulators (Shahid et al, 2013). Low yield resulting from poor nutrient status of the soil has been identified as one of the major factors limiting okra production (Ajayi et al, 2017).…”

Purpose : Fruit peels waste is one of the waste accumulate in huge quantity every day. It is a serious problem and need to be managed to make environment free from pollution. Fruit peels are very rich in macro and micro nutrients that are beneficial for plant growth. By using fruit peel as fertilizer we can reduce load of wastes and can get more benefits than inorganic fertilizer. Research Method : The experiment was carried out in a Completely Randomized Design with six treatments having twenty replicates. Treatments were, recommended fertilizer application at basal and topdressing (T1, control), half dose of recommended fertilizer application at basal and topdressing times with 1g of banana peel powder (T2), 1g of pomegranate peel powder (T3), 1g of orange peel powder (T4), 0.5g each of banana and pomegranate peel powders (T5) and 0.5g each of orange and banana peel powders (T6) at both times. All agronomic practices were followed as per Department of Agriculture, Sri Lanka except fertilizers. Findings : The results reveals that application of fruit peel powder at basal and top dressing had significant differences (P<0.05) on plant height, number of leaves per plant, leaf area, chlorophyll content, days to 50% and 100% flowering, dry weights of leaves, stem, root and fruit, fruit length and girth. At 1st, 2nd, 3rd and 4th picking, and the highest value was obtained in T6 and lowest value in T1. Originality/ Value : Application of fruit peel powder into the soil leads to improve growth and yield of okra in sandy regosol compared to recommended inorganic fertilizer and present study suggested that, among the all tested treatments, half recommended fertilizer application at basal and topdressing times with 0.5g each of orange and banana peel powders at both times would be the most suitable fruit peel powders to get higher growth and yield of okra in sandy regosol.
