Abstract:

The effect of Gibberellin Hormonal Response and Grafting methods on the Growth and Yield of Okra was investigated, with the aim of inducing variability that could be exploited in the improvement of some quality traits in Okra plants. Gibberellin, grafting and a combination of grafting with Gibberellin) were applied on to the Okra seeds. The seeds of Okra were treated at four different concentrations of Gibberellin (0.1mM, 1.0 mM, 2.0 mM and 0.0 mM as control) after which some of the mutants were grafted using tongue grafting method at seedlings stage. The other set of seeds were not treated with the hormone but were grafted at seedlings stage. The results obtained revealed highly significant difference (P≤ 0.01) in the effects of Gibberellin on survival rates, number of fruits, and fruit weight. Similarly, highly significant differences (P≤0.01) were found between the treatments in Survival rate, except on the number of fruits and fruit weight, where no significant differences exist. More so, significant differences were found in the traits between the seasons except in fruit number. The result showed that Gibberellin and grafting improve important quality traits of Okra. The mutants and grafted Okra could be grown both during the rainy and dry seasons, while 0.1 mM concentration of Gibberellin and grafting improve some important quality traits of Okra that could be utilized for further improvement of Okra. However, the response of Okra to grafting was higher. Based on the findings, the study concluded that, grafting improves some important quality traits of Okra that are of high economic value and possible recommendations that could be made.

Abstract:

Red cotton bugs [Dysdercus spp. (Hemiptera: Pyrrhocoridae] are among the most destructive pests of cotton and many other crops. Red cotton bugs (RCBs hereafter) damage cotton plants by sucking sap and deteriorate lint by staining. The incidence of RCBs causes boll injury along the field margins neighboring with various peripheral areas. The adjacent habitat/crops strongly mediate the population dynamics of RCBs. However, limited is known about the impact of adjacent habitat on population dynamics of RCBs and lint quality. This two-year field study evaluated the impact of adjacent habitat (okra, unpaved road, water channel and Eucalyptus trees) on population dynamics of RCBs and lint quality of cotton. The RCBs were sampled weekly from margins to 4 meter inside the cotton field. The RCBs’ populations were monitored and plucked cotton bolls were examined for internal damage. The highest incidence of RCBs was recorded for cotton field adjacent to okra and water channel. Similarly, the highest number of damaged bolls were observed for the field side neighboring with okra and water channel. Furthermore, the highest number of unopened bolls were recorded for okra and water channel sides with higher percentage of yellowish lint. Field sides bordering with Eucalyptus trees and unpaved road had lower RCBs incidence and lint staining. Nonetheless, RCBs incidence was higher at field margins compared to field center indicating that population was strongly affected by adjacent habitat. It is concluded that sowing okra and weedy water channels adjacent to cotton would support RCBs population and subsequent lint staining. Therefore, water channels must be kept weed-free and okra should not be sown adjacent to cotton. Nonetheless, detailed studies are needed to compute monetary damages caused by cotton pests to the crop. Furthermore, effective management strategies must be developed to manage RCBs in cotton to avoid lint-staining problem.

Abstract:

The use of saline water in agricultural production will be increasingly necessary in the next decades. However, postharvest quality may be compromised, as in okra, due to salt stress and/or factors inherent to storage and transportation. In this context, developing alternative methods of preservation, including lactic fermentation, may be a promising way to maintain and even improve the nutritional quality of okra. Thus, the objective was to evaluate the production components of okra subjected to different levels of water salinity and doses of potassium fertilization, and further to evaluate the preservation by lactic fermentation of okra fruits produced under water salinity. The first experiment was carried out in lysimeters under field conditions in Neossolo Regolítico (Psamment) of sandy loam texture in Pombal-PB, in a randomized block design in a 5 x 5 factorial scheme, testing 5 levels of irrigation water salinity (0.3; 1.3; 2.3; 3.3, and 4.3 dS m-1) and 5 doses of potassium fertilization (75; 112.5; 150; 187.5, and 225 mg of K2O kg-1 of soil), with three replicates. After that, the okra fruits produced under the different salinity levels were stored in six mixtures of salts present in lactic fermentation brine (100-0-0, 0-100-0, 0-0-100, 50-50-0, 0-50-50, and 50-0-50 of NaCl, CaCl2, and KCl, respectively), under a 5 x 6 factorial, with three replicates, in a completely randomized design. The post-harvest quality, after fermentation, was evaluated based on their physicochemical characteristics. Irrigation water salinity negatively affected the average length, average weight, titratable acidity, soluble solids/titratable acidity ratio, and pH of the okra fruits. Potassium doses increased the average diameter of okra fruits, minimizing the deleterious effects of irrigation water salinity. The vitamin C contents of pickled okra fruits were not compromised by salt stress. Among the lactic fermentation brines, the formulation containing the proportion NaCl:CaCl2 stands out as promoting the highest titratable acidity and soluble solids content in pickled okra fruits.

Abstract:

Okra (Abelmoschus esculentus), a fruit vegetable consumed in several countries, especially in Africa, contributes to the fight against poverty and malnutrition due to its nutritional value. However, in Burkina Faso, its cultivation during the dry season that lasts about 9 months remains dependent on the availability of water resources. Thus, during this period that lasts about 9 months, because of this situation, okra producers are dealing with very diversified sources of water. However, the rehydration of seeds, which is the first step towards germination, depends mainly of the water. Therefore, the aim of the present study was to test the germinability of okra seeds under different irrigation waters in order to propose alternative sources. Thus, seeds of three ecotypes of okra (B2, G259, and L2) were germinated using five water types (dam water, wastewater from the sewage treatment plant (WTP), well water, dishwashing greywater, and distilled water). The results showed a significant influence of the water type on the germination velocity and the growth speed of the radicle. Indeed, using wastewater from the WTP, the germination velocity was very significantly lower than those obtained with the other sources (P<0.0001). Furthermore, seeds irrigated with WTP wastewater germinated less than other water types. Nevertheless, the germination rate obtained with dishwashing greywater (86.93 ± 0.14%), which is not used generally in agricultural production, is comparable to the rates obtained with other water types. Furthermore, the study showed a significant effect of the ecotype on the germination rate (P≤0.001). In addition, dam water significantly enhanced root growth compared to WTP (P<0.0001). In view of the results and because of water scarcity in Sahelian regions, dishwashing greywater, which is generally discarded, could be collected and used for the germination of okra.

Abstract:

Cultivation of okra (Abelmoschus esculentus L.) which is a commonly grown vegetable crop in the tropics is constrained by depleting soil fertility. Use of foliar fertilizer as a supplement has been successfully reported in the temperate region hence there is need to determine the effect of foliar liquid fertilizer on okra growth and nutritional quality. Field experiments were conducted at the Abeokuta (Federal University of Agriculture [FUNAAB] ) and Ibadan (National Horticulture Research Institute [NIHORT] ), between May and August 2015 to evaluate the response of two okra varieties to types and rates of organic-based foliar fertilizer application. Experiment was a 2 × 2 × 5 factorial combinations laid out in Randomized Complete Block Design with three replicates at both locations. Factors were okra variety (LD88 and NHae47-4), the fertilizer types (D.I. Grow Green ® and D.I.Grow Red®) and four rate of foliar applications (0 [control], 300, 600 and 900 ml/ha) while NPK 15:15:15 served as check. The results showed that the D.I.Grow Red® at 300ml/ha produced the higher Ash (8.23%), fat (2.54%,), moisture (14.65%), and carbohydrate (47.31%) at Abeokuta while 600 ml/ha produced significantly the higher ash, crude fibre, moisture and carbohydrate (9.37%, 15.94%, 9.13%, and 52.02%), respectively in Ibadan. The study concluded that okra variety LD88 had superior growth performance. Application of D.I.Grow Red® at the rate of 300 ml/ha at Abeokuta and 600 ml/ha at Ibadan enhance fruit nutritional quality of okra. Therefore, 300 and 600 ml/ha is recommended to farmers in Abeokuta and Ibadan, respectively.

Abstract:

Okra fruit contains phenolic compounds as natural antioxidant. The aim of this research was to analyze the effect of different types of fertilizers on production and quality of two okra varieties. The experiment was conducted in October 2017 to February 2018 at Bogor Agricultural University experimental field at Leuwikopo, Darmaga, Bogor (-6033’49.3”SL, 106043’30.7’’EL). The experiment used nested randomized complete block design with 2 factors and 4 replications. The first factor consisted of two okra varieties with different colour (red and green okra). The second factor was fertilizer types consisted of no fertilizer, organic (cow manure), combination of organic + inorganic, and inorganic fertilizer. The results showed that fertilizer types significantly affected plant height and fruit N content but did not affect fruit production. Red okra had a higher plant height, lower number of leaves and leaf K content than those of the green okra. The interaction effect of both factors was significant on total phenolic content in fruit and P content in leaf. The highest total phenolic content in fruit was showed by red okra with inorganic fertilizer, although it was not significantly different to those of red okra with combination organic + inorganic fertilizer, and also to green okra with organic fertilizer. The highest P content in leaf was found in red okra without fertilizer, however it was not significantly different to red okra with combination organic + inorganic fertilizer, green okra with organic fertilizer, and green okra with inorganic fertilizer.Keywords: inorganic fertilizer, leaf nutrient, organic fertilizer, phenolic compound

Abstract:

Post-harvest is an activity processed from harvesting to becoming a product. Post-harvest handling aims to maintain the quality and minimize the loss of the agricultural product. Post-harvest loss of okra is the reduction of the okra harvest amount from picking up to transporting process. Many factors can cause the post-harvest loss of okra. This study aimed to determine the causal sources of the okra loss. This study used FMEA and fishbone diagram. Fishbone diagram was used to identify the causes of the okra loss in a fishbone skeleton. FMEA was used to give the value on the causes of the okra loss by assessing the severity, occurrence and detection to get the RPN value. The RPN value was used to rank the potential causes of the loss. From the result of the study, it was found that there were 4 main factors causing the okra loss which had the RPN value above the RPN critical value. It were lack of picker accuracy and training or counseling, handling pets and diseases, and age factor of picker. Keywords: fishbone diagram, FMEA, okra, post-harvest loss

Abstract:

Soil properties are very important to be well understood before planting any crop. Different types of soil will possess different properties. The properties of soil will influence the yield and quality of crops. For instance, poor soil properties will produce low quality of okra, thus reducing consumer demand. It is necessary to find conditions that are suitable for soil in order to get the best okra quality to fulfil the demand of consumers. The purpose of this research is to determine the physiological quality of harvested okra on different types of soil which are peat soil (T1), mineral soil (T2) and alluvium soil (T3). Each treatment was replicated five times and was applied with the same amount of fertilizer (NPK 12: 12: 17: 2); 10 g. Parameters in term of quality of physical appearances were taken once after the fruits were harvested. The parameters taken include the length of fruit (cm), the diameter of fruit (mm), the colour of fruits and fruit tenderness. Parameters for growth performance were also taken for each treatment. The result obtained shows a high significant difference in term of physical features of okra such as length of fruit (cm), the diameter of fruit (mm) and fruit tenderness for each treatment. Harvested alluvium soil -based okra was found to be the most promising for fruit yield, physical quality and quantitative characteristics. This is because the result of parameters of alluvium soil (T3) is higher than peat soil and mineral soil in term of length of fruits; 17.18 cm, diameter of fruit; 19.42, yield produced; 9.8 and tenderness; 9.2. The T3 soil also has rich in micronutrients especially potassium. In conclusion, properties of soil whether chemically or physically will influence the yield and quality of crops either directly or indirectly.

Abstract:

The purpose of this paper is to investigate the impact of vacuum microwave drying on the quality of okra. The curves of colour, fracture resistance, rehydration ratio and the content of vitaminC were obtained at various drying times, vacuum degrees and microwave powers. Results showed that an increase in drying time and microwave power resulted in serious colour change when compare the dry product to fresh okra. However, the higher the vacuum, the slighter the colour changed. The fracture resistance decreased and the brittleness was good when drying time was increased to high level of 14min and 16min. Increasing vacuum degree also made fracture resistance decreased; rehydration ratio increased with the time and microwave power increased, but decreased if the time exceeds 14min. The rehydration ratio of okra is also affected by the vacuum degree, increasing which led the rehydration ratio increased significantly at the beginning of drying and then slowly; the greater the drying time and microwave power, the more lost of vitaminC, however, higher vacuum degree was found to be beneficial to save the vitaminC.

Abstract:

The fruit thinning treatment is known to be able to improve seed quality. This research aimed to increase the yield component and seed quality on two okra varieties (Naila and Zahira) through fruit thinning. This experiment was conducted in May until September 2018 at the Leuwikopo IPB Field, Postharvest Laboratory, and Seed Testing Laboratory, Department of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural University. This experiment conducted using the two-factors nested design, which is a fruit thinning factor as subplots consisting of five levels and okra varieties consisting of two levels. The results showed that the fruit thinning factor influenced the parameters of yield components (fruit length and weight per fruit) and 1,000 seeds weight. The variety factor influenced most of the yield component parameters and seed quality in okra plants. The thinning treatment of the first two fruits and elimination of one fruit interval resulted in the highest physical quality of seed based on 1,000 seeds weight (67.99 g).

Abstract:

In this study, the phenolic profiles and bioactivities of five representative cultivars of okra collected in China were investigated. Noticeable variations of phenolic compounds and their bioactivities were observed among these different cultivars of okra. The contents of total flavonoids (TFC) in “Shuiguo”, “Kalong 8”, “Kalong 3”, “Wufu”, and “Royal red” ranged from 1.75 to 3.39 mg RE/g DW, of which “Shuiguo” showed the highest TFC. Moreover, five individual phenolic compounds were found in okra by high performance liquid chromatography analysis, including isoquercitrin, protocatechuic acid, quercetin-3-O-gentiobioside, quercetin, and rutin, while isoquercitrin and quercetin-3-O-gentiobioside were detected as the main phenolic compounds in okra. Moreover, all tested okra exhibited significant antioxidant activities (2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity, 2,2’-azino-bis (3-ethylenzthiazoline-6-sulphonic acid) radical scavenging capacity, and ferric reducing antioxidant power) and inhibitory effects on digestive enzymes (lipase, α-glucosidase, and α-amylase). Indeed, “Shuiguo” exhibited much better antioxidant activities and inhibitory activities on digestive enzymes, which might be attributed to its high TFC. Results suggested that okra, especially “Shuiguo”, could be developed as natural antioxidants and inhibitors against hyperlipidemia and hyperglycemia in the fields of functional foods and pharmaceuticals, which could meet the increasing demand for high-quality okra with health-promoting properties in China.

Abstract:

ABSTRACT Okra, Abelmoschus esculentus (L.) Moench, is a vegetable with annual fruit native to hot regions of Africa, well adapted to the conditions of the Northeast and Southeast regions of Brazil, where it is widely used by small farmers. This study aimed to evaluate the effect of mineral and organic fertilization on the production and quality of okra fruits. The experiment was conducted in randomized block design, with three replicates and eleven treatments defined according to a Baconian matrix. Treatments consisted of doses of N (0, 100, 200 and 300 kg ha-1), P (0, 100, 200 and 300 kg ha-1) and K (0, 80, 160 and 240 kg ha-1), as well as absence and presence of organic compost (30 t ha-1). The following parameters were evaluated: plant height, stem diameter, number of leaves, production of fruits plant-1, number of fruits plant-1, fruit length and diameter and fruit quality (pH, soluble solids, titratable acidity, vitamin C and electrical conductivity). The crop is demanding in terms of K and N fertilizations, with increments of 15.8 and 36% in the mean number and diameter of fruits, respectively. Organic fertilization did not influence the vegetative growth of okra, but was beneficial to the production of fruits with higher vitamin C content, 52% higher than the contents found in fruits produced without such input.

Abstract:

Little information is available on the influence of temperature on plastic films wrapped okra (Albelmoschus esculentus) for their postharvested conservation. This works investigated the influence of the temperature and PVC film on the development of chilling injury and storability from one of the most popular Brazilian cultivar of okra cv. Amarelinho in fruits stored at 5, 10ºC and at 25ºC. Fruits were harvest at commercial maturity stage with length ranging from 8 to 12 cm, and immediately wrapped in PVC over a polystyrene tray and than stored until visible deterioration or wilting symptoms. Lowering the temperature of storage room from 25 to 10 or 5ºC decreased the weight loss in both PVC wrapped and control fruits, with a lower rate at 5ºC. By reducing the temperature to 5 or 10ºC and wrapping the fruits in PVC film, the relative water content of the fruit pericarp was maintained throughout the storage, while at 25ºC the high weight loss was associated with significant reduction of the water content. The development of chilling symptoms was delayed by the presence of PVC film in fruits stored at 5ºC. However, at 10ºC symptoms of pitting were not developed in PVC wrapped or control fruits up to tenth day of storage. The rate of chlorophyll degradation was diminished by reducing the temperature and by wrapping the fruits with PVC film. The appearance of severe chilling symptoms at 5ºC was associated to less chlorophyll in the fruit pericarp on the control as compared to their content in the PVC wrapped fruits.

Abstract:

This study aimed to evaluate the yield and the quality of the fruits of two okra cultivars (Abelmoschus esculentus), due to the varying doses and types of biofertilizers. The experiment was conducted the period September to December of 2017, at the experimental Piroás Farm, in the city of Redenção-CE, Brazil. The experimental design used was entirely randomized, in factorial design 5 × 2 × 2, referring to the five doses of the biofertilizer (0, 0.5, 1, 1.5 and 2.0 L plant-1 week-1), versus two types of liquid biofertilizers (bovine and caprine under aerobic fermentation) and two okra cultivars: Santa Cruz 47 and Clemson Spineless. The number of the fruits per plant, the average mass of the fruits, yield, the length and diameter of the fruit and peel thickness of the okra fruit, were increased according to the increase on the biofertilizers doses. The cultivar “Santa Cruz 47” presented higher values in the length of the fruit, whereas the cultivar “Clemson Americano 80” was superior in the variables “average fruit mass” and “diameter of the fruits”.

Abstract:

<p>Okra is a vegetable widely grown in the tropics, sub-tropics and warmer areas of the temperate zones. Fruit quality plays an important role in marketability and it is mainly related to the characteristic pod length. This work was intended to classify okra fruits belonging to different genotypes (a local variety - LV - and the cultivars Emerald, Clemson Spineless and Annie Oakley II) according to their length and to compare certain quality attributes. LV fruits were considerably firm although they were smaller, thus they should be more suitable for canning or pickling. The hybrid material (Annie Oakley II) yielded high quality fruits. These fruits may be destined for fresh consumption, given that they showed lower fibrousness. At the same time, they had high dry matter content, being suitable for dehydration. Okra fruits highlighted for their contribution of phenolic compounds.Total phenols levels significantly increased with fruit size in LV fruits, meanwhile no significant difference was observed for Annie Oakley II samples. Total flavonoids content showed a similar tendency although values did not differ significantly. Total flavonoids represented between 18-22% of the total phenols contents for the analyzed samples.</p>

Abstract:

Abstract Field experiments were carried out at the Teaching and Research Farm, Landmark University, Omu-Aran, Kwara State, Nigeria, in the cropping seasons of 2015 and 2016. The soil at the site of the experiment is an Alfisol classified as an Oxichaplustalf or a Luvisol. The trial consisted of sole and combined applications of urea fertilizer (U) applied at 0, 60, and 120 kg·ha−1 and maize cob ash (M) applied at 0, 3, and 6 t·ha−1. The results showed that U and M alone or in combinations increased the soil chemical properties, growth, yield, and mineral composition of okra compared with the control. M alone at 3 t·ha−1 produced optimum soil chemical properties, yield, and mineral composition of okra fruit. U alone at 60 kg·ha−1 produced optimum yield of okra, while growth and mineral composition were increased when urea fertilizer was applied at 120 kg·ha−1. The treatment with U applied at 60 kg·ha−1 in combination with M applied at 3 t·ha−1 (U60M3) produced the highest values of okra yield, while U applied at 120 kg·ha−1 in combination with M applied at 3 t·ha−1 (U120M3) has the highest growth and highest N, K, Ca, Cu, and Fe contents of okra fruit. Compared with the control and using the mean of the two years, U60M3 increased okra fruit yield by 93.3%. Therefore, for viable production of okra in low nutrient soil of the Nigeria derived savanna or similar soils elsewhere, 60 kg·ha−1 U + 3 t·ha−1 M (U60M3) is recommended. However, for improved mineral quality of okra, 120 kg·ha−1 U + 3 t·ha−1 M (U120M3) is recommended.

Abstract:

The effects of temperature, storage time and water pH on the coagulation performance of okra seed protein in water treatment were assessed. In a jar test experiment, okra salt extract achieved a notable improvement in treatment efficiency with storage time and showed good performance in quality after thermal treatment at 60, 97 and 140 °C temperatures for 6, 4 and 2 hours, respectively. The performance improvement of more than 8% is considered to be due to the denaturation and subsequent removal of coagulation-hindering proteins in okra seed. Furthermore, the results of a sodium dodecyl sulphate polyacrylamide gel electrophoresis analysis show two distinctive bands of protein responsible for the coagulation process after denaturation. It was further shown that at optimal coagulant dose, the pH of the treated water remained unaffected as a result of the protein's buffering capability during coagulation. Therefore, denatured okra seed exhibited improved performance compared to the native crude extract and offers clear benefits as a water treatment coagulant.

Abstract:

Okra (Abelmoschus esculentus L. (Moench) is one of the most important vegetable crops grown in Nepal. The crop is susceptible to various insect pests of which jassids (Amrasca biguttula biguttula Ishida.) is most predominant which reduces production and deteriorates seed quality of okra. A field study was conducted at Horticulture Farm, Agriculture and Forestry University, Rampur, Chitwan, Nepal to elucidate the effect of sowing date and nitrogen levels on the population and damage of jassids from April to September 2018. Three levels of nitrogen (100, 200 and 300 kg N ha-1) and five sowing dates (8th April, 20th April, 2nd May, 14th May and 26th May, 2018) were evaluated in randomized complete block design with three replications. Results indicated that the highest damage score was recorded in okra which was sown on 8th April (2.39) followed by 20th April (2.31) and 2nd May (1.26). The highest damage score of jassids was obtained with the use of nitrogen at the rate of 200 kg ha-1 (1.94) followed by 300 kg/ha (1.72) and 100 kg ha-1 (1.54). Mean population of jassids was maximum with okra sown on 20th April (29.91) and minimum with okra sown on 26th May (6.95). This study showed that late planting i.e. 26th May and applying low level of nitrogen i.e. 100 kg N ha- 1is an effective approach for reducing the jassids population and its damage in okra.

Abstract:

Okra is a vegetable crop that has a high selling value and the production of okra is more exported than sold domestically. The demand for okra from year to year continues to increase from various countries, especially Japan, which imports the most okra from Indonesia. Fertilization of phosphorus (P) fertilizer to fulfill nutrients and provision of arbuscular mycorrhizal fungi (CMA) for more efficient and maximum absorption by plants. Phosphorus (P) fertilizer can increase the production and quality of okra. The aim of this study was to determine the combination of treatment of arbuscular mycorrhizal fungi and which dosage of P fertilizer was best to increase the yield of okra production. The design used was a completely randomized design (CRD) with factorial treatment consisting of two factors. The first factor is the dose of arbucular mycorrhizal fungi (CMA) consisting of 4 levels, namely (0; 160; 320; 480) and the second factor is the dose of P fertilizer (75; 100; 125; 150). Parameters observed were plant height, number of leaves per plant, volume of roots, number of fruits per plant, weight of fresh fruit per plant and weight of plant dry corpse. Based on the analysis of variance, it showed that the interaction was significantly different on the variables of root volume, plant height, number of fruits and fruit weight. Based on research, the CMA dose of 320 kg / ha and the dose of 125 kg / ha gave the highest production results.

Abstract:

The present study was conducted on okra (Abelmoschus esculentus (L.) Moench) genotypes collected from Benishangul Regional State of Western Ethiopia. The objective of this study was to assess the genetic diversity of okra within a regional state based on qualitative traits at Melkassa Research Center during the rainy season of 2019. The results showed that the okra genotypes collected from the regional state had a wide variation in growth habits, leaf, fruit, flower, and seed in their qualitative traits, namely, shape, color, and other quality factors like pubescence which is a determinant factor in consumer preference. Therefore, the result of this study is an indicator for the presence of a higher chance to develop okra varieties highly preferred by domestic and foreign markets through selection/crossing of okra genotype collected from Benishangul Gumuz regional state; as an example, accession 29622 had a smooth texture of fruit with green fruit color which is preferable by consumers. However, the genotypes showed greater variability for plant branching habits that has its effect mainly related to contamination of branches and fruits by soilborne microorganisms and the soil itself during irrigating fields. Finally, it is better if molecular characterization is to be followed by the current morphological characterization and evaluation work.

Abstract:

Okra possesses a short shelf-life which limits its marketability, thereby, the present study investigates the individual and combined effect of 1-methylcyclopropene (1-MCP) and modified atmosphere packaging (MAP) on the postharvest storage life of okra. The treated/ untreated okra samples were stored at ambient (i.e., 27 °C) and low (i.e., 7 °C) temperatures for eight and 20 days, respectively. Results revealed that the 1-MCP and/or MAP treatment successfully inhibited fruit softening, reduction in mucilage viscosity, and color degradation (hue angle, ∆E, and BI) in the product resulting in a longer period of shelf-life. However, MAP with or without 1-MCP was more effective to reduce weight loss in okra stored at both ambient and cold storage conditions. Additionally, ascorbic acid and total antioxidants were also retained in 1-MCP with MAP during cold storage. The 1-MCP in combination with MAP effectively suppressed respiration rate and ethylene production for four days and eight days at 27 °C and 7 °C temperature conditions, respectively. According to the results, relatively less chilling injury stress also resulted when 1-MCP combined with MAP. The combined treatment of okra pods with 1-MCP and MAP maintained the visual quality of the product in terms of overall acceptability for four days at 20 °C and 20 days at 7 °C.

A survey was conducted to assess the export supply and value chain analyses of okra (<i>Abelmoschus esculentus</i> L.) in Bangladesh. The survey was consisted of primary and secondary data from semi-structured interview of key persons involved in the supply chains of export market of okra and from the review of relevant reports and literature. Primary data were collected from 40 middlemen (from Ulokhola-10, Kawranbazar-7, Shambazar-8, Jatrabaribazar-5, Chandina-10), 5 service providers and 20 okra exporters of Dhaka city. It was found that the supply chain was fragmented and complex. The middlemen predominantly controlled the supply chains. Post-harvest management was poor, resulting low quality of the produce and low prices in the export market. The supply chain indicated that, the growers consumed 7.8% of their own product while 92.2% was sold out. About 28% farmers sold their okra at the field/farm-gates and 72% was sold in the local markets. The value chain analyses (VCA) revealed that, the net profit margin was 15.77 Tk/kg for both the UK and the Middle East markets whereas the net profit was 5.86 Tk/kg in local markets. The cost of airfreight was highest (63.97%) of all costs followed by the production cost of okra (16.85%) and the cost of packing (13.40%).The Agriculturists 2015; 13(1) 133-139

Abstract:

The production of okra using seedlings is a practice increasingly used by farmers. However, this system still lacks further research involving substrates, tray types, cell volume, pest control and disease. For this it is important to determine the optimum size of the plots, in order to reduce the experimental errors and the expenses with the experiment. The objective of this work was to determine the optimum plot size for experiments involving okra seedlings produced in Styrofoam trays of 128 cells using different methods. The methods were the maximum curvature, the maximum curvature with bootstrap simulation and the maximum curvature of the coefficient of variation. The evaluated characteristics were aerial part height, stem diameter, aerial dry matter, root dry matter, total dry matter and quality of seedlings as measured by Dickson quality index. The results showed that the optimum plot size is different between the evaluated characteristics and for characteristics there is no significant difference in the optimum plot size between the three different methods. The optimum size for evaluating okra seedlings produced in Styrofoam trays of 128 cells is 10 seedlings per plot and is indicated the use of the maximum curvature method using a bootstrap simulation.

Abstract:

A combination of room cooling and the use of thermal insulation materials to maintain okra quality under simulated storage and transportation was evaluated. Okra pods were packed in plastic baskets and either cooled at 18 °C or not cooled in a room for 2 h. After either room cooling or no cooling, the okra pods were covered with three different materials: (1) perforated linear low-density polyethylene (P-LLDPE), (2) two layers of heat-reflective sheet with thin nonwoven (HRS+TNNW), and (3) metalized foam sheet (MFS). Typical handling (TP) without cooling and covering with P-LLDPE was used as the control. The six treatments were conducted during simulated storage (18 °C for 48 h) and transportation (30 °C for 15 h). Results showed that MFS gave the best insulation properties (Qx and R-values), followed by HRS and TNNW. After room cooling, both HRS+TNNW and MFS materials delayed the time for pulp temperature to reach 18 °C (10 h), compared to P-LLDPE (2 h). TP presented the highest mass loss (17.8%) throughout simulated conditions, followed by cooling plus P-LLDPE (15.2%) and either of the thermal insulation materials with or without room cooling (3.6% to 5.2%), respectively. TP, cooling plus P-LLDPE, and no cooling plus MFS (44% to 56%) showed the highest percentage of decay, while cooling combined with both HRS+TNNW and MFS gave the lowest decay incidence (11–21%). Findings demonstrated that room cooling combined with HRS+TNNW had the highest efficiency for preserving cool temperature and reducing decay, compared to TP and room cooling plus MFS.

Abstract:

A field experiment was conducted during kharif season of 2012 to study the biochemical efficacy of Homa organic farming practices in okra (Abelomoschus esculentus var. Arka Anamika) and laid out in randomized block design with 18 treatments replicated thrice. The treatments consist of control treatments i.e. conventional control and homa control; homa treatments (Agnihotra and Om Tryambakam homa) and non-homa treatments; and liquid organic manures viz, Panchagavya, Jeevamruta and Gloria Biosol for soil and foliar application. Among the control treatments, organic control recorded highest growth, yield and quality parameters than other controls. Soil and foliar application of Gloria Biosol was significantly superior over all the treatments in terms of growth, yield and quality attributes and recorded 20.28% more plant height and 21.41% more yield than organic control treatments. Ascorbic acid and free total phenol content of okra fruits in homa treatments were also significantly superior over all the treat-ments and recorded 15.45% and 5.33% more over organic control, respectively. Thus, it may be recommended that soil and foliar application of Gloria Biosol, among all the Homa organic treatments, will give the better crop produc-tivity and its produce quality.

Abstract:

Okra [Abelmoschuscaillei (A. Chev.) Stevels] drying was studied by a factorial experiment under randomized complete block design using a laboratory-scale hot-air dryer. Two osmotic solution concentrations (40 and 60 oBrix of sucrose), three osmotic process durations (60, 120 and 180 min) and four drying temperatures (50, 60, 70 and 80 oC) were considered with each trial conducted in triplicates. Drying rate was determined as the ratio of change in mass of okra to the change in drying time as drying progresses. The ash content, crude fibre, crude fat, crude protein, bulk density, least gelation concentration and water absorption capacity were investigated as quality parameters. Model equations were developed using Essential Regression (ESSREG) analysis and Statistical Package for Social Sciences (SPSS) to relate output parameters to process variables. The results showed that an optimum drying rate of 16.69 g/h could be achieved by subjecting okra to osmotic dehydration pretreatment using a solution of 40 oBrix sucrose for 149.10 min and dried with a temperature of 80 oC. The ash content of 3.76% could be obtained at 40 oBrix, 180 min and 50 oC. An optimum value of 29.65% was obtained for crude fibre at an osmotic solution concentration of 60 °Brix, osmotic process duration of 180 min and drying temperature of 80 oC. Crude fat content of okra has 4.03% as its optimum value and this corresponds to a combination of 60 oBrix osmotic solution concentration, 180 min osmotic process duration and 74.60 oC drying temperature. An osmotic solution concentration of 60 °Brix, osmotic process duration of 60 min and drying temperature of 80 oC should be selected to give the optimum crude protein of 14.12%. Predicted values of drying rate, ash content, crude fibre, crude fat, crude protein and water absorption capacity (WAC) compared favourably with the observed values. This implies the models reliably predicted the drying characteristics of okra very well in terms of these output parameters. It could be inferred from this study that the drying process of okra can be optimized under different drying conditions. Further studies should be carried out on the factors that affect the storability of dried okra for long-time storage and preservation. An investigation into the use of sodium chloride for osmotic dehydration pretreatment as a means of improving the post-drying palatability of okra should be considered for further study.

Abstract:

A field experiment was conducted to evaluate the effect of light reflecting colored mulches and only one time spraying with selected insecticides to control the insect vector of Okra Yellow Vein Mosaic Virus (OYVMV) whitefly (Bemisia tabaci) at the central farm of Sher-e-Bangla Agricultural University, Dhaka-1207. The experiment was carried out in three blocks layouted with RCBD comprising eight treatments viz. T0 (control/no spray), T1 (1 time spray with imitaf), T2 (1 time spray with protect), T3 (1 time spray with tiddo plus), T4 (1 time spray with terbine), T5 (light reflecting silver color mulch), T6 (light reflecting red color mulch) and T7 (light reflecting black color mulch) with three replications. The mulches were used before sowing and insecticides were sprayed at 30 DAS. It was observed that among the light reflecting colored mulches, the lowest disease incidence (11.48%) was recorded in the plots which mulched with red color mulch (T6). Among the insecticides, the lowest disease incidence (30.17%) was recorded in plots that was sprayed with terbine (one time). Yield and yield contributing characters, morphological and physiological features of okra plant that changes due to disease infection which cause damages in okra production and reduce the fruit quality as well as market value was also the part of this study. Yield and yield contributing characters showed significant variance among the selected treatments. In the relationship study, it was noticed that the yield and plant height was showed negative relationship with disease incidence. However, considering all measuring parameters, spraying with terbine (one time) and used red color mulch may be recommended as good management approaches that will give higher okra production and lower disease incidence of Okra Yellow Vein Mosaic Virus (OYVMV).

Abstract:

SUMMARYDifferences in the age at which okra pods were harvested (4, 7, 10 or 13 days after pod set) had no effect on vegetative growth or pod yield, but pods harvested more than seven days after pod set were of poorer quality. The reduction in pod quality arose mainly from an increase in crude fibre and a reduction in the moisture, crude protein and ash content of older pods.
