  An experiment was conducted in Rampur, Chitwan, Nepal, in a Randomized Complete Block Design (RCBD) with five treatments: T1 (sand:soil, 1:1) [control], T2 (sand:cocopeat:perlite, 1:1:1), T3 (perlite:sand, 1:1), T4 (sand:cocopeat, 1:1), and T5 (peat moss:perlite, 1:1). Each treatment was replicated four times with a total of 300 planted cuttings. The key parameters evaluated were sprouting percentage, shoot growth (length, leaf number, and branch number), and root development (length, number, fresh, and dry biomass). Analysis of data was done using R-Studio, and Duncan’s Multiple Range Test (DMRT) was performed at a 5% significance level. The results revealed that peat moss:perlite (1:1) demonstrated the highest shoot growth with shoot length of 6.00, 14.38 and 28.78 cm at 30, 60, and 90 Days After Planting (DAP) respectively. Leaf number were 6.25, 13.12, and 19.57, while branch numbers were 1.76, 2.00, and 2.18 at the same intervals., Additionally, the fresh root weight was recorded 8.74 g. Sand:cocopeat:perlite (1:1:1) recorded the highest sprouting percentage (81.66%) and root length (17.11 cm), while sand:cocopeat (1:1) achieved the highest root number (18.37) and dry root weight (0.99 g). Perlite:sand (1:1) exhibited moderate performance with sprouting percentage 69.99%, and root length 12.56 cm. In contrast, control (sand:soil) showed the least favorable results with the lowest sprouting percentage (58.33%), the fewest number of roots (7.81), and the minimum root length (9.73). This study concludes that peat moss:perlite (1:1) is the most effective growing medium for bougainvillea propagation, offering a practical solution to enhance rooting success and growth performance. Sand:cocopeat (1:1) with maximum dry weight of root and maximum number of roots emerged as a reliable alternative, proving the effectiveness of the medium.

  A two trial greenhouse experiment was carried out at Rwanda-Israel Horticulture Centre of Excellence located at Mulindi Station to evaluate seedling quality on growth, yield and quality of tomato. The seedlings were grown in different growing media and produced seedlings with varying quality indices. The growing media of peat moss 100% (T2) and sand + goat manure + carbonized rice husks 50%: 10%: 40% (T8) were revealed in seedlings with the highest mean quality indices of 31 and 28 respectively, while sand 100% (T2) presented the lowest quality indices during both trials. The transplants were planted in polybags filled with 2:1 of topsoil and kitchen manure arranged in a randomized complete block design (RCBD) with four replications. Collected data were subjected to analysis of variance and means were separated using HSD test at a 5% level of significance. The results revealed that the seedlings grown in T1 (S1) and T8 (S8) consistently presented tomatoes with better growth performance and yield. S1 and S8 produced mean yield of 93.59 and 92.35 t/ha respectively while S2 had the lowest yield with 53.86 t/ha. The fruit produced from seedlings grown in T4 (S4) had the highest mean sugar acid ratio of 5.88 but not significantly different from 5.61 and 5.44 of S1 and S8 respectively. Hence, there was a positive relationship among seedling quality and growth and yield performance of tomato but not in fruit quality.
