After tomato, onion (Allium cepa) is the second important culinary vegetable in Uganda. Purple blotch disease affects productivity worldwide, with up to 100% losses. Eight onion varieties are grown in Uganda but no screening for resistance to this disease had been done. The objective of this study was to identify resistant varieties and establish effects of the disease on productivity. The Pathogen strains were obtained from three key onion producing regions: Mbale, Kabale and Kasese. Screen house experiments were conducted using six varieties: Bombay red, Hazera, Hybrid, Red coach, red creole and Tanzania. Trays 76 cm length x 36 cm breadth was used for the experiment. Each tray was planted with 25 seeds at 4-5 cm depth in sterile soil, and watered as required for 21 days. The seedlings were transplanted and inoculated with two virulent pathogen strains from each study region. After six weeks, disease severity was rated following 0-5 Lodha (1976) scale; Percent Disease Index (PDI) was calculated. Growth parameters: plant height, leaf length and number; bulb diameter, fresh and dry weight were recorded. Results indicated that none of the varieties showed immune resistant, moderately resistant or highly susceptible response to the disease: ratings 0, 1, 2 and 5 respectively. Red coach, Red creole and Hazera expressed Moderate susceptible response (Rating 3); Bombay red, Hybrid and Tanzania showed susceptible response (Rating 4). Tanzania was the most susceptible to all isolates with Kb17 giving the highest PDI and Red coach was the least affected with lowest PDI of 16.7. All the growth parameters were affected significantly by the disease (P < 0.05), and showed a considerable reduction compared with the control experiment. In conclusion, Red coach, Hazera and Red creole were recommended to farmers for planting.

“…Minimum plant height 45.87 cm was observed in T 3 (All Green H-1), while the remaining treatments were moderate in their growth habit. Similar findings were reported by Ahmad et al [3] in cucumber, Hossain et al [4] in Indian spinach, Varalakshmi and Devaraju [5] in indian spinach, Ali et al [6] in onion, Dunsin et al [7] in tomatoes, Malshe et al [8] in okra, Sharma et al [9] in beetroot, Karthick et al [10] in ridge gourd, Mshelia and Muhammad [11] in okra, Singh et al [12] in okra, Ddamulira et al [13] in onion, Gul et al [14] in cucumber, Ashraf et al [15] in okra, Khadijeh et al [16], Nath et al [17] in spinach, in beetroot and Kurre et al [18] in ridge gourd.…”

A field experiment was carried out at the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during the Rabi 2021-2022 with a view to determine the performance of different varieties of spinach beet (Beta vulgaris var. bengalensis) for its growth, yield under Prayagraj climate and to work out the economics of various treatments. Under this experiment, overall 7 varieties were sown under tags T1 (Pusa Jyoti), T2 (All Green), T3 (All Green H-1), T4 (Green Iron), T5 (Palak- Ashirwad), T6 (Sudevi Green Spinach), T7 (Supriya) which was laid out in randomized block design (RBD) with three replications. From the present investigation, it was concluded that variety Pusa Jyoti performed best in respect of all parameters specially yield (64.44q/ha) at Prayagraj climatic condition. The benefit-Cost ratio (1.61) of variety Pusa Jyoti was found to be the highest therefore, it can be suggested to farmers to adapt it in cultivation practices.
