Diversity in nutrient content and consumer preferences of sensory attributes of peanut (Arachis hypogaea L.) varieties in Ugandan agroecosystems
2021

The cultivated peanut (Arachis hypogaea L.) is one of the most widely consumed legumes globally due to its nutrient content, taste, and affordability. Nutrient composition and consumer preference were determined for twenty local farmer (landrace) and commercial peanut varieties grown in the Nakaseke and Nakasongola districts of the central wooded savanna of Uganda through sensory and laboratory evaluation. Significant differences in nutrient content (p < 0.05) among peanut varieties were found within and across sites. A significant relationship between nutrient content and consumer preference for varieties within and across sites was also realized (Wilk’s lambda = 0.05, p = 0.00). The differences in nutrient content influenced key organoleptic characteristics, including taste, crunchiness, appearance, and soup aroma, which contributed to why consumers may prefer certain varieties to others. Gender differences in variety selection were significantly related to consumer preference for the crunchiness of roasted peanut varieties (F = 5.7, p = 0.016). The results imply that selecting different varieties of peanuts enables consumers to receive different nutrient amounts, while experiencing variety uniqueness. The promotion of peanut intraspecific diversity is crucial for improved nutrition, organoleptic appreciation and the livelihood of those engaged in peanut value chains, especially for the actors who specialize in different peanut products. The conservation of peanut diversity will ensure that the present and future generations benefit from the nutritional content and organoleptic enjoyment that is linked to unique peanut varieties.

The objective of the research was to study the nutrition uptake (nitrogen, phosphorus, and potassium,) and the grain production of five rice varieties representing modern, new plant type and local varieties under application of inorganic, organic and combined inorganic-organic fertilization. Five rice varieties were Way Apoburu and IR-64 (modern varieties), Midun and Sarinah (local varieties from Sukabumi and Garut, respectively), and Fatmawati (new plant type variety). Five fertilizer treatments were (1) full recommendation dosage of inorganic fertilizer (250 kg urea/ha, 100 kg SP-36/ha, and 100 kg KCl/ha), (2) ¼ recommendation dose of inorganic fertilizer + rice straw, (3) ½ recommended dose of inorganic fertilizer + rice straw, (4) rice straw, and (5) green manure from Crotalaria juncea biomass. The results showed that there was no specific response of rice varieties to the fertilization treatments, even though there was specific nutrient uptake pattern and yield of each variety, and there was significant effect of fertilizer treatment to nutrient uptake and rice yield. Nutrient uptake and grain yield indicated that nutrient imobilisation occurred at 1stseason, however the availability of N, P, K nutrients increased at 2nd and 3rdseason on rice straw and green manure treatments. Rice straw application caused lower nutrient uptake and grain yield than full dosage inorganic fertilizer at 1st season but both were not significantly different at 2nd and 3rdseason. Application of rice straw with ½ dosage of inorganic fertilizers was not significantly different from full dosage of inorganic fertilizers in nutrient uptake and grain yield. Modern varieties showed higher level of N absorption than that of new type variety although it was not significantly different with that of local varieties, whereas the P and K uptake of modern varieties was lower than that of local and new plant type varieties. The modern varieties also showed higher level of dry grain per hill than that of local and new plant type varieties. However yield per ha of all varieties tended to be similar.
