“…Ali et al, (2015) recorded that seed yield of onion in the ranged of 370 -500 Kg/ha. Ahmed et al, (2018) reported highest onion seed yield i.e 580 kg/ha against purple blotch of onion. Zakirul islam (2013) observed maximum seed yield (649.40 kg/ha) with low incidence and intensity of purple blotch of onion.…”

“…Meanwhile, cultural practices, including crop rotation, field sanitation, intercropping, optimal spacing, good drainage, and the utilization of resistant varieties like Red Star F 1 , Red Pinoy F 1 , and Red Passion F 1 , have demonstrated effectiveness in manag-ing purple blotch disease (Ahmed et al, 2018;MOA, 2019).…”

Onion (Allium cepa L.) is the second most produced vegetable globally, following tomato and plays a vital role in both cuisines and daily diets. However, the threat of diseases, such as purple blotch caused by Alternaria porri, poses a substantial risk to onion production, particularly in Nyeri County, Kenya. Despite its critical impact on farming, there is a lack of information on farmers' knowledge of purple blotch in this region. This study aimed to assess the onion farming practices and farmers' understanding of purple blotch disease across various agro-ecological zones (AEZs) in Nyeri County. Specifically, the study examines farmers' demographics, cultivated onion varieties, and their knowledge of purple blotch disease. Farms were selected using cluster random sampling. Data were collected from 100 onion farmers through semi-structured questionnaires, and statistical analysis was performed using the chi-square test in Scientific Analysis System (SAS) version 9.4 at α=0.05. The findings revealed that while the Rucet F1 onion variety was popular among the farmers (52%), there is no significant association (X2 (6, 100) = 11.947, p = 0.063) between the choice of variety and AEZs. Similarly, the preferred source of onion seeds, mainly Agroshop (84%), showed insignificant association (X2 (9, 100) = 7.153, p = 0.621) with AEZs. Despite 65% of farmers reporting knowledge about onion diseases, there is no significant association (p > 0.05) between their awareness of purple blotch and AEZs. In conclusion, the study highlights a significant gap in farmers' understanding of purple blotch disease, emphasizing the need for training programs to enhance disease identification skills. Early detection can empower farmers to implement proactive measures, ultimately improving onion productivity. This study recommends diversifying onion varieties for disease resilience, promoting awareness and training on purple blotch identification, engaging women and youths in farming, and fostering collaborative networks for ongoing knowledge exchange and improvement in onion cultivation in Nyeri County.

One of the important factors in the success of True Seed of Shallot (TSS)-based shallot production is the right seeding technology. The study aimed to obtain appropriate nursery techniques for producing high-quality seedlings to increase shallot productivity. The experiment was conducted in Cirebon Regency, West Java, Indonesia, from May to October 2021, using a factorial randomized block design with three treatment factors and three replications. They consisted of shallot varieties (V) (Trisula, Bima, Lokananta, and Maserati); seedlings age (U) (45 and 60 days); and seedling population density (P) (5, 7.5, and 10 g m−2 of TSS). The results revealed that seedling performance was negatively correlated to the bulb yield and revenue cost ratio (R/C). The use of young seedlings enhanced bulb production and R/C ratio in all varieties but had varied effects on cluster alterations in Maserati, Bima, and Trisula varieties. Young Lokananta seedlings prepared in the nursery at a seed density of 7.5 g m−2 proved to be the best treatment to generate the highest bulb production (39.92 t ha−1) and the highest R/C (3.62). Farmers are expected to implement seedling preparation techniques using young seedlings and managing seed populations in diverse varieties to maximize bulb production and R/C.
