Different nursery growing systems and growth media improved germination and seedling growth of fever tea (Lippia javanica)

An experiment was set up in a Completely Randomized Design (CRD) to examine the influence of nursery growing methods and growth medium on fever, tea germination, and seedling development. Two nursery growth methods (Conventional-CON and Float tray system FTs) and six different growing medium (pine bark, peat moss, coco peat, vermiculite, sand, and cattle manure) were used. ANOVA was used to compare treatment means, and means were separated using the Least Significant Difference (LSD) at a 5 % significance level. The nursery growing method and growth material exhibited a strong interaction regarding the germination index, germination percentage, seedling height, leaf area, root length, density, and final crop stand. The float tray approach yielded the greatest germination index for peat moss and the lowest for cattle manure. In the float tray method, peat moss and coco peat had the highest germination percentages, whereas cattle manure had the lowest. Under the float tray technique, the tallest seedlings emerged in peat moss and the smallest in coco peat. Peat moss had the most leaf area in the float tray system, whereas coco peat had the least in the conventional technique. Peat moss in the float tray system had the highest root length density while coco peat in the conventional technique had the lowest. Peat moss in the float tray system had the highest final crop stand, whereas seedlings in the conventional and float tray systems had nothing. based on the findings, it is recommended that fever tea seedlings be grown on peat moss using the float tray metho

Hydropriming improves seed germination in horned melon (Cucumis metuliferus E. Mey. Ex Naudin) landraces

The global popularity of horned melon highlights the need of sound crop establishment processes, since uniform and quick seed germination has a substantial influence on crop yield and quality. Using a Completely Randomised Design (CRD) with a factorial structure, the effects of hydro priming durations (0, 8, 16, 24, 32, and 40 h) on seeds of two horned melon landrace (L1&L2) were investigated. Hydro priming had significant (P>0.05) influence on several germination indices (germination percentage, relativized percentage, mean germination rate, germination index, synchronization, duration to 50 % germination, mean daily germination, peak value, and germination value). Among the germination indicators tested, landrace (L2) exhibited a considerably stronger germination response than L1. The findings also reveal a curvilinear relationship between priming length and germination percentage, with 24 hours being greatest proportionately. The mean germination rate, germination index, mean daily germination, peak value of germination, and germination value all rose as the hydro priming duration increased. Primed seeds germinated more quickly than unprimed ones. With increasing priming duration, the synchronization index fell linearly. The interaction between landraces and hydro priming was not significant (P>0.05) for final seed germinated, relativized germination, and synchronization indices, but it had a significant impact on all other indices. Because the efficacy of hydro priming tends to lessen with extended soaking, we recommend using it for a maximum of 32 hours. Future study should concentrate on alternative priming chemicals and the applicability of various priming solutions for various agroecosystem
