Potatoes (Solanum tuberesum, L) are one of the main foods for the needs of the world community. Therefore, increasing potato crop production is considered important. For this purpose, the utilization of a mixture of rice husk biochar with compost can provide the best results up to three times the planting season. Coffee skin can also be found in form of compost for the utilization process. However, due to the lack of farmer’s knowledge about the benefits that can be provided by skin compost to maintain the level of soil fertility. This study aims to analys the effect of biochar and coffee skin compost on the growth and yield of potato crops. Plant height, number of shoots, number of tubers per clump, and per plot tuber weight was a parameter of observation. This experiment used a factorial randomized planting block design using several doses of biochar and coffee skin compost.  The treatment of biochar dosage did not significantly affect all parameters observed. The treatment of the effect of doses of coffee skin compost had a very significant effect on plant height at all ages of observation. The average plant height increases with the higher doses of red coffee skin compost given has a very significant effect on the number of tubers per clump and the weight of per plot tubers. There was no real interaction between the biochar dose and the red coffee skin compost dosage against all observed parameters.

Tomato (Solanum lycopersicon) is an important crop cultivated and consumed worldwide. It provides wide variety of nutrients with many health-related benefits like, protection against cancer, maintains blood pressure and reduces blood glucose level in people with diabetes. Despite the importance of tomato, its growth and yield is limited by choice of cultural practices mainly earthing up and pruning system. There is also limited knowledge on the effect of integrating pruning and earthing up on tomato growth and yield. This study investigated the effect of integration of pruning and earthing up on the growth and yield of tomato. A split-plot experimental design, arranged in a Randomized Complete Block Design, with three replications was used. The study investigated two factors i.e. pruning system in the main plot (single stem, double stem, and triple stem) and earthing up in sub-plots. (0 cm, 10 cm, 20 cm, and 30 cm. The findings of the study revealed that earthing up and pruning system had a significant (p ˂ .05) effect on plant height and stem girth diameter at 45, 52, and 59 days after transplanting. The single stem pruning system and earthing up to 30 cm gave the tallest plant height with an average plant height of 69.80 cm in cultivation 1 and 71.50 cm in cultivation 2. Single stem pruning system and earthing up to 30 cm gave the largest stem girth diameter with mean stem girth diameter of 2.16 cm in cultivation 1 and 2.25 cm in cultivation 2. Triple stem pruning system, earthing up to 30 cm recorded the highest number of marketable fruits with 64500 fruits/hectare in cultivation 1 and 64333 fruits/hectare in cultivation 2. To improve tomato growth and development which consequently improves marketable yields, farmers are encouraged to consider triple stem pruning system with earthing up to level 30 cm.
