Strategi Pemupukan Tanaman Karet Dalam Menghadapi Harga Karet Yang Rendah

Abstract

Pemeliharaan tanaman karet melalui pemupukan merupakan salah satu langkah penting yang harus dilakukan untuk mencapai pertumbuhan dan produksi yang optimal. Akhir-akhir ini ketersediaan pupuk yang terbatas, harga yang terus meningkat, dan harga karet yang rendah menyebabkan kegiatan pemupukan pada perkebunan karet sering tertunda. Selain penundaan kegiatan pemupukan juga terjadi pengurangan dosis dan bahkan meniadakan kegiatan pemupukan. Tulisan ini bertujuan untuk mengkaji hasil-hasil penelitian dalam upaya peningkatan efisiensi pemupukan pada tanaman karet sehingga biaya pemupukan dapat dikurangi. Hasil-hasil penelitian sebelumnya menunjukkan bahwa pemupukan dapat dikurangi sampai 75% dari dosis pupuk tunggal apabila menerapkan teknologi pemupukan menggunakan pupuk majemuk dengan tambahan slow release agent yang sering disebut dengan Slow Release Fertilizer (SRF) dan upaya lain dengan menggunakan kombinasi pupuk tunggal dengan pupuk hayati. Selain itu penentuan dosis rekomendasi harus mempertimbangkan sifat tanah sehubungan dengan kapasitas tanah dalam menyediakan unsur hara untuk tanaman, faktor lingkungan yang mempengaruhi efisiensi pemupukan, serta kebutuhan tanaman akan unsur hara sesuai dengan umur, produksi, dan kesehatan tanaman. Pada kondisi pekebun yang mengalami kesulitan melakukan pemupukan akibat harga karet yang rendah maka penundaan pemupukan selama dua tahun belum memberikan efek kerugian finansial bagi pekebun.

Optimizing Nutrient Management: Slow-Release NPK Granule Fertilizer Enhanced with Zeolite and Humic Acid for Sustainable Plantation Crops

“…In the effort to improve fertilization efficiency in rubber and coconut kopyor plantations, [19] suggests employing compound fertilizers with the addition of a slow-release agent commonly known as SRF. Zeolite and humic acid play a significant role in regulating nutrient release dynamics from NPK Granule Plus fertilizer.…”

Factors Affecting the Productivity of Rubber Plantations in West Kalimantan Province

“…Rubber plant wood can also be utilized for construction materials, such as houses, furniture, and other structures, if the rubber garden is to be revitalized. [8] Investment Domestic and international investment can be described as the expenditure or expenditure of investment or corporations to buy production products in order to expand the ability to manufacture goods and services accessible in the economy. Increased investment will support a rise in output volume, resulting in more productive employment options and an increase in per capita income while at the same time increasing people's welfare [9] Investment activities in the region have so far played an important role, among others, in increasing people's income and being labor intensive, which ultimately led to the creation of economic transformation [10].…”

Relationship between Economy and Environment of the Natural Rubber Plantation in Major Producers

“…One of the aspects is the soil nutrient which is related to soil capacity to provide nutrients for plants, environmental factors such as weed conditions that affect fertilization efficiency, and the need for a specific nutrient according to age, production and condition of a plant. Therefore, [25] explained the importance of the analysis of soil and plant leaves in a certain area which is often called the LSU (Leaf Sampling Unit). The fertilizer recommendations for a better rubber plant cultivation can be made based on the general dosage of experimental results, soil nutrient index, leaf nutrient index, disease attack index, wind disturbance index and nutrients depleted due to increased production [26].…”
