Assessment of Postharvest Management of Frafra Potato (Solenostemon rotundifolius (Poir.) J. K. Morton) | Chapter 09 | Current Topics in Agricultural Sciences Vol. 5

 The Frafra potato (Solenostemon rotundifolius (Poir.) J.K. Morton) is an underutilised tuber crop grown in Ghana, Nigeria, Benin, Togo, Burkina Faso, and Mali's interior Savanna areas. When compared to other tuber crops, the crop has agronomic advantages in low soils and yield advantages with limited production inputs. The study focuses on the crop's most important integrated agricultural production and postharvest management strategies. The focus was on existing and prospective areas to improve postharvest quality and shelf-life, which is still a relatively new subject. Due to their high moisture content, vulnerability to physical damage, and high metabolic activity, tubers, like other root and tuber crops, suffer significant postharvest losses (PHL). Primary physio-chemical deterioration (such as weight loss, respiration, compositional alterations, and sprouting) and decay induced by microbial invasion and physiological problems are the main causes of PHL. PHL losses result in a drop in quantity and quality, as well as price reductions. The extent of PHL in Frafra potato and crop-specific postharvest management approaches are both unknown. PHL, on the other hand, may fall within the global estimate of 30 to 60% across root and tuber crops. To reduce PHL, integrated crop management strategies like as variety selection, planting material quality, soil fertility management, field pest and disease control, excellent harvesting and handling practises, suitable storage, and postharvest treatments must all be taken into account. This chapter includes background knowledge and key technology for effective Frafra potato postharvest management. Access to enhanced storage and processing technology can certainly boost production to commercial levels. As more study information and recommendations are developed in future studies, such bits of information can be updated.

Effects of Thermal and Non -Thermal PreProcessing Methods on Physical Attributes of Jackbean (Canavalia ensiformis) Seed | Chapter 7 | Challenging Issues on Environment and Earth Science Vol. 6

 On the physical properties of Jackbean (Canavalia ensiformis) seed, the impacts of thermal and non-thermal pre-processing procedures were investigated. Roasting and autoclaving as thermal pre-processing methods and sprouting as a non-thermal pre-processing method were used on jackbean seeds received from the germplasm unit of the International Institute of Tropical Agriculture (IITA) in Ibadan, Oyo State, Nigeria. A digital venier calliper was used to measure length, width, and thickness, while a formular was used to calculate the sphericity index and the aspect ratio, which is the ratio of length and width. The results of physical characterization revealed that all of the pre-processing procedures studied have the seed's effects All of these metrics decreased in connection to roasting, save the sphericity index: length 19.00- 15.00 mm, breadth 13.00- 11.00 mm, thickness 10.75- 10.55 mm, and sphericity index 72.88- 80.20 percent. For all of the treatments used, the aspect ratio declined from 1.46 to 1.33 as pre-processing time increased. For the untreated seed, the kernel density (g/cm3), bulk density (g/cm3), and density ratio were 1.24, 0.73, and 0.59, respectively. However, following sprouting and autoclaving, the length increased from 19.00 to 24.00 mm, the width increased from 13.00 to 18.00 mm, and the thickness increased from 10.75 to 11.10 mm, while the sphericity index decreased from 72.88 to 67.46 percent. These outcomes are a crucial in the development of seed processing equipment, hence promoting the seed's industrial application. Other underutilised legumes on the point of extinction can benefit from these techniques.

Studies on Different Substrates and Container Volumes in the Emergence and Ministumps Formation of Physalis peruviana L. | Chapter 7 | Cutting-edge Research in Agricultural Sciences Vol. 9

 To obtain high-quality seedlings, good production techniques must be used. The container and the mode of propagation are important considerations. The goal of this study was to see how two substrates and container volumes affected the emergence and formation of Physalis peruviana L. mini-stumps. This research was conducted from September to November 2019 in a greenhouse owned by the Federal University Network of the Holy Spirit. completely randomized, in a factorial scheme with three containers (R1 = tube with a volume of 50 ml; R2 = tube with a volume of 280 ml; and R3 = plastic cups with a volume of 500 ml) and two substrates (S1 = Bioplant® and S2 = Provaso® + soil 1:1), totaling six treatments, four replications, six plants per experimental unit, and 144 plants After 90 days of experimentation, it is recommended to use a volume of 280 ml, combined with the substrate Provaso® + soil, for better emergence and emission of the shoots of Physalis peruviana L.
