Cassava (Manihot esculenta Crantz) is a local food that has long been cultivated and consumed by almost all people in Sikka Regency. In cultivating cassava, farmers generally still use traditional techniques so that it has not had an impact on increasing cassava production. Cassava production can be improved through several efforts, namely using superior varieties, setting planting distance, and fertilizing activities according to plant needs. This study aimed to determine the effect of planting distance and types of inorganic fertilizers on cassava production in the Sikka Regency. This research was designed using a factorial randomized block design, namely planting distance (T) and type of fertilizer (P). Each factor consists of several levels that combine six treatments, including T2P0, T2P1, T2P2, T3P0, T3P1, and T3P2. Each treatment was repeated three times to obtain 18 experimental units. Observation variables include the number of tubers per plant and tuber wet weight per plant. Observation data were analyzed using analysis of variance (ANOVA). The results showed that the addition of Urea, SP36, and NPK Phonska (complete) fertilizers could increase the wet weight of cassava at a planting distance of 2x1 m. and the planting distance of 2x1 m had a significant effect on the number of tubers/plant, and at the planting distance of 1x1 m supported by fertilization was able to increase the wet weight of tubers/plants.

Corn is a food crop commodity that has an important and strategic role in national development. The demand for corn continues to increase in line with the increase in population as a result of the increased need for food. Increasing maize production can be done through spacing and fertilization. This study aims to determine the effect of the interaction between planting distance and fertilizer type as well as the effect of every single factor. This study was designed using a factorial randomized block design consisting of two factors, namely spacing (T) and type of fertilizer (P). Each factor consists of several levels that are combined to produce 9 treatments including T1P0, T1P1, T1P2, T2P0, T2P1, T2P2, T3P0, T3P1, and T3P2. Each treatment was repeated three times in order to obtain 27 experimental units. The observation variables included plant height and number of leaves as measured at 52 days after planting, as well as maize production per plot. Observation data were analyzed using analysis of variance (ANOVA) and continued with the LSD test at the 5% level. The results showed that the interaction between spacing and application of fertilizers had a significant effect on maize production per plot with the highest yield found in the T2P2 treatment interaction of 7.57 kg/plot. Whereas for the number of leaves and height of maize plants aged 52 DAS, the interaction between the two factors had no effect. A single treatment of spacing and application of fertilizers did not affect all the observed variables.
