“…Plant nutrients are very influential on the development of tissues to plant organs, namely the vegetative and generative components so that they affect production [2]. Deficiency of one of the nutrients can cause inhibition of vegetative growth and can also reduce the production of oil palm [3]. Oil palm require more macro nutrients than micro nutrients.…”

The potential oil content in oil palm plants is influenced by genetic and environmental factors. Several factors affect the quality of palm oil, including variety and nutrition, such as macro nutrients, especially N, P, K, and Mg. These nutrients play a role in fruit formation, increase in average weight bunches (BJR), plant health and play a role in increasing oil content. This study aims to the relationship of leaf, stalk, spikelet, and mesocarp nutrients to oil content. This exploratory study uses a quantitative descriptive method on 3 varieties of DxP Oil Palm: Socfindo, Topaz and Damimas: with year of planting 2014, each covering an area of ± 10 Ha and the observation period 2018-2019. The results showed that there was a relationship between leaf K nutrient on the Damimas variety, leaf Ca nutrient on the Socfindo variety and leaf B, leaf Zn, K rachis and Mg rachis nutrient on the Topaz variety to the O/B value. The regression model for this relationship sequentially is Y = 13.68 + 10.97 K_ leaf (R2 = 0.336); Y = 14,917 + 13,915 Ca_leaf (R2 = 0.314); and Y = 39.645 - 0.519 B_ leaf + 0.728 Zn_ leaf - 9.519 K_rachis - 41.434 Mg_rachis (R2 =0.595). In addition, only the Socfindo variety found an effect of stalk and spikelet nutrient content on the O/B value. These nutrients are K stalk nutrients with the regression model Y = 0.42 + 6.29 K_stalk (R2 = 0.372), and P, K, Mg and Ca spikelet nutrients with the regression model Y = 6.851 - 233.372 P_Spikelet + 14.585 K_Spikelet + 141.326 Mg_Spikelet - 66.348 Ca_Spikelet (R2 = 0.635).

The rapid development of oil palm replanting areas will lead to ecological problems such as plant disturbing organisms. Pest and disease attacks are obstacles farmers face when developing their farms, especially in smallholder oil palm plantations. This study aims to examine the components of cultivation techniques, environmental factors, and human resources that influence the application of IPM on smallholder oil palm replanting land in Pangkalan Kuras District, Pelalawan Regency, Riau Province. The methods used in this study included the purposive determination of 60 respondents, data collection through interviews with farmers, field surveys, and data analysis. The results showed that socio-economic aspects influenced farmers' actions in implementing IPM. Farmer knowledge about pests and diseases of oil palm plants was 36%. Farmers have applied several pest and disease control techniques in oil palm cultivation on replanting land. However, most farmers (60%) are still unfamiliar with the term IPM, need to learn the role of natural enemies in pest control in the field, and lack regular monitoring.
