Production Problems

Dolpa is the largest district and one of the major apple-producing districts of Nepal. It had seemingly an increasing trend of production and productivity of apple despite having low productivity than the national average. A study was carried out to study the production and marketing status of the district. Preliminary studies were done and a household survey was carried out among 125 apple-growing farmers from different wards of Tripurasundari and Thulibheri Municipality. 10 commercial farmers in Juphal along with five wholesalers and retailers each based in Nepalgunj were also interviewed to observe the marketing status of apple. 16.59 % of the income was generated through apple production behind government jobs and other agricultural activities. Apple farming was found profitable with BC ratio of 1.39. Training, technical assistance, experience, and landholding were found to have a positive influence on the apple-growing farmers. The overall productivity of apple in the area was 7.55 MT per ha, which was lower than the national average. Improper Post-harvest handling and storage facility had created a post-harvest loss of 14.33 %. Most of the produce was marketed within the district only due to lack of good roads. Lack of irrigation and insect pest attack were the major production problems whereas lack of storage and poor transportation as the major marketing problems. Increasing the frequency of extension works, technical assistance and good transport of the produce were needed to be focused.

Leafy vegetables like lettuce and spinach are prone to significant post-harvest losses during handling and storage. The pre-harvest treatment of crops with biostimulants offers a sustainable strategy for reducing post-harvest losses. Earlier studies focused on the effect of plant biostimulants applied individually. In this study, we studied the efficacy of a combined application of two commonly used plant biostimulants: Ascophyllum nodosum extract (ANE) and humic acid (HA). Interestingly, the combination of both biostimulants improved early growth of lettuce and spinach compared to ANE and HA alone. Among the combinations used in this study, 0.25% ANE + 0.2% HA produced significantly higher fresh and dry biomass in lettuce and spinach compared to the other treatments and the control. Pre-harvest treatment of combination of 0.25% ANE and 0.2% HA significantly reduced the loss of fresh biomass during post-harvest storage. The combination of 0.25% ANE and 0.2% HA reduced lipid peroxidation during storage with an increase in total ascorbate, phenolic, and antioxidant capacity of spinach and lettuce. These results suggest that a combination of ANE and HA reduces post-harvest losses of spinach and lettuce more effectively than when applied individually.

Post Harvest Loss

The consumer demand for fresh fruits and vegetables increases every year, and farmers need a low cost novel method to reduce post-harvest loss and preserve the quality of fresh fruits and vegetables. This study identifies a method to induce soil bacteria to biosynthesize a nitrile compound that potentially enters the plants tissue and negatively affects climacteric ripening and delays the ripening process at 20-30˚C. This study used soil rich with soil microbes, to delay the ripening of climacteric fruit. The soil was treated with nitrogen, a heavy metal, and ethylene gas. Ethylene induced the soil to delay the ripening of organic bananas and peaches. A prototype transportation container maintained fruit fresh for up to 72 h at 20-30˚C. The fruit retained color, firmness, texture, no bruising and minimal spotting. The soil also prevented fungal infection in all samples. GC-MS analysis suggests ethylene induced the soil microbes to release an acetonitrile compound into the gaseous environment. The nitrile is released in low concentrations, but mature plants (fruits) contain very low levels of indole-3-acetonitrile (IAN) or indole-3-acetic acid (IAA). The nitrile may obstruct or modify the mature plants (fruit) late stages development process, thus delay the climacteric ripening process and retarding the physiological and phenotypic effects of fruit ripening. We believe this study may have strong applications for post-harvest biotechnology.

Vegetables are important in human diets as a side dish eaten either cooked or raw as in salads. They are important for their nutritional contribution as major sources of minerals, vitamins, nine essential amino acids, beneficial phytochemicals, fibre and interesting colour from an aesthetic point of view. Despite the immerse health benefits offered by vegetables there are challenges encountered in their post-harvest handling and storage up to consumption. Challenges include post-harvest losses due to diseases. Some losses occur even at household level when vegetables are not stored appropriately when stored under the sink where humidity can be high leading to an environment which promotes diseases. Diseases in the post-harvest chain are caused by bacteria and opportunistic pathogenic fungi. Post-harvest losses of vegetables are not only a threat to nutritional security but a threat to food security as well. The aim of this research study was to document major post-harvest diseases of vegetables found in the Kingdom of Eswatini and to suggest appropriate management strategies or ways of alleviating them.

In response to increased pest and disease problems, potato farmers use pesticides, which could raise environmental and health concerns. This study sought to promote proper and safe pesticide-handling practices by providing data needed to guide pesticide regulation policy and training for extension staff and farmers. A household survey was conducted in three major potato-growing agroecological zones of Uganda. Two hundred and four potato farmers were interviewed about the type and source of pesticides they use in potato cultivation, the frequency of applications, the use of protective clothing, and cases of pesticide poisoning. The types of pesticides used in potato were fungicides (72%), insecticides (62%), and herbicides (3%). Overall, use of personal protective equipment was low, that is, gumboots (73%), gloves (7%), face masks (16%), and long sleeve shirts (42%). Forty-three percent of farmers who applied pesticides reported having experienced skin itching, 25% skin burning sensation, 43% coughing, 60% a runny nose, 27% teary eyes, and 42% dizziness. An IPM approach involving only moderately to slightly hazardous pesticides when pest and disease incidence has reached economic injury levels and by considering all safety measures during application and storage would be environmentally recommendable and result in reduced health risks.

Além disso, o intuito deste trabalho foi comparar o ângulo de repouso das sementes em diferentes protótipos. O estudo foi realizado no laboratório da Universidade Federal Rural da Amazônia, Tomé-Açu (PA), para verificar: teor de água, biometria, esfericidade, volume unitário, porosidade e ângulo de repouso. O teor de água utilizou cinco amostras (50 sementes), biometria obteve eixos ortogonais de 100 sementes, e utilizadas 20 sementes para esfericidade e volume unitário. Ainda, obtidas médias em 3 equipamentos de ângulo de repouso, (5 repetições). Como resultado, o teor de água (b.u.) foi baixo, (0 a 10%); a esfericidade variou de 61,45 a 90,66%; volume unitário foi de 0,03 a 0,13 cm3 e as porosidades foram (0,69, 0,77 e 0,78). Os ângulos de repouso nos equipamentos (A- adaptado em relação a B; B- equipamento estabelecido e C- protótipo alternativo) foram, respectivamente: 38,85; 31,92 e 32,14°, não diferindo estatisticamente. Ademais, o estudo buscou trazer informações sobre a espécie e colaborar com trabalhos de construção, operação e adaptação de equipamentos de secagem e armazenamento.   Palavras-chave: esfericidade, porosidade, volume unitário.   PHYSICAL CHARACTERIZATION OF ANNATTO (Bixa orellana L.) SEEDS, AIMED POST-HARVEST PROCESSES   ABSTRACT: Annatto demonstrates economic importance in the commercialization of ground grains for color and dye production; however, there are few studies on their physical characteristics in post-harvest processes. In addition, the aim of this work was to compare the rest angle of seeds in different prototypes. The study was carried out in the laboratory of Federal Rural University of the Amazon, Tomé-Açu (PA), to verify: water content, biometrics, sphericity, unit volume, porosity and angle of repose. The water content used five samples (50 seeds), biometrics obtained orthogonal axes of 100 seeds, and 20 seeds were used for sphericity and unit volume. Still, averages were obtained in 3 equipment of angle of rest (5 repetitions). As result, the water content (b.u.) was low (0 to 10%); sphericity ranged from 61.45 to 90.66%; unit volume was 0.03 to 0.13 cm3 and porosities were 0.69, 0.77 and 0.78. The rest angles in the equipment (A- adapted in relation to B; B- established equipment and C- alternative prototype) were, respectively: 38.85; 31.92 and 32.14°, not differing statistically. In addition, the study sought to bring information about the species and collaborate with construction, operation and adaptation of drying and storage equipment.   Keywords: sphericity, porosity, unit volume.
