Abstract

Penelitian ini bertujuan untuk mendapatkan dosis pupuk NPK yang paling baik untuk mempercepat pemulihan tanaman karet pasca musim kemarau pada lahan kering. Penelitian ini dilaksanakan di Kebun Warga di Desa Putak, Kecamatan Gelumbang, Kabupaten Muara Enim, Sumatera Selatan. Koordinat lokasi 3°10'32.1"S 104°28'53.8"E. Penelitian dilaksanakan dari Oktober 2024 sampai Januari 2025. Penelitian disusun menggunakan rancangan acak kelompok (RAK). Ada lima perlakuan dan lima ulangan sehingga diperoleh 25 tanaman sampel yang terdiri dari P0 = 0 g NPK/pokok (sebagai kontrol), P1 = 350 g NPK/pokok, P2 = 700 g NPK/pokok, P3 = 1050 g NPK/pokok, dan P4 = 1400 g NPK/pokok. Tanaman karet yang dijadikan sampel penelitian adalah karet yang berusia lebih dari 14 tahun. Semua data dianalisis menggunakan analysis of varians (ANOVA). Hasil penelitian menunjukkan bahwa pemberian pupuk NPK berpengaruh nyata terhadap pemulihan tanaman karet terhadap volume lateks dan berat basah lateks beku dan mempercepat pertumbuhan daun baru. Selanjutnya, perlakuan pemupukan NPK tidak menunjukkan pengaruh nyata terhadap lama aliran Lateks, berat kering lateks beku, kadar kering karet, lilit batang, dan tebal kulit. Di duga aplikasi pupuk NPK 1400 g pada tanaman karet pasca musim kemarau pada akhir penelitian dapat memulihkan volume lateks 36% lebih tinggi dibandingkan 0 g NPK (kontrol).
