      Abstract
      Keberhasilan budidaya kelapa sawit sangat ditentukan oleh ketepatan strategi pemupukan yang disesuaikan dengan varietas dan kondisi fisiologis tanaman. Penelitian ini bertujuan menganalisis pengaruh perbedaan varietas terhadap serapan hara tandan buah segar (TBS) serta menghitung unsur hara makro yang terangkut keluar lahan sebagai acuan rekomendasi pemupukan. Studi observasional cross-sectional selama 4 bulan di Kawan Batu Estate, Kalimantan Tengah, menggunakan sampel brondolan dari varietas Dami dan Marihat. Hasil menunjukkan varietas Dami memiliki akumulasi hara makro lebih tinggi (N 0,46–0,51%; P 0,05%; K 0,48–0,53%) dibanding Marihat (N 0,41%; P 0,04%; K 0,40%), sehingga lebih optimal mendukung pengisian mesokarp dan pembentukan asam lemak. Sementara itu, varietas Marihat unggul dalam serapan Boron (6,17 mg/kg) yang berperan memperkuat dinding sel buah, dengan kadar Ca dan Mg pada kedua varietas tergolong seimbang (Ca 0,10–0,11%; Mg 0,05–0,06%). Temuan ini diharapkan menjadi pedoman dalam merancang rekomendasi pemupukan presisi yang spesifik lokasi dan varietas untuk meningkatkan produktivitas serta efisiensi input secara berkelanjutan.
       
      The success of oil palm cultivation highly depends on appropriate fertilization strategies tailored to plant physiological conditions and varieties. This study aimed to analyze the effect of variety differences on nutrient uptake in fresh fruit bunches (FFB) and to calculate macro-nutrient removal from the field as a basis for fertilization recommendations. A cross-sectional observational study was conducted over four months at Kawan Batu Estate, Central Kalimantan, using loose fruit samples from two superior varieties (Dami and Marihat). Macronutrients (N, P, K), secondary nutrients (Ca, Mg), and micronutrient (B) were analyzed. Results showed that Dami variety accumulated higher macronutrients (N 0.46–0.51%; P 0.05%; K 0.48–0.53%) compared to Marihat (N 0.41%; P 0.04%; K 0.40%), thus more optimally supporting mesocarp filling and fatty acid synthesis. Meanwhile, Marihat variety excelled in Boron uptake (6.17 mg/kg), which strengthens fruit cell walls, while Ca and Mg levels in both varieties were relatively balanced (Ca 0.10–0.11%; Mg 0.05–0.06%). These findings are expected to serve as a guideline for designing precise, site-specific and variety-specific fertilization recommendations to improve productivity and input efficiency sustainably.
