Abstract

Kadar hara merupakan proses untuk mengetahui kandungan unsur hara yang ada didalam jaringan tanaman. Kadar hara diperoleh melalui survey lapangan dan analisis unsur hara di laboratorium. Penelitian ini bertujuan untuk mengetahui Kadar hara N, P dan K serta merekomendasi penggunaan hara N, P dan K untuk tanaman kelapa sawit sehingga dapat meningkatkan produksi kelapa sawit. Penelitian ini dilakukan di PT. Peniti Sungai Purun Kabupaten Mempawah. Hasil Analisis menunjukkan bahwa kadar hara N, P dan K pada Blok G50 tergolong defisiensi sampai optimum, Blok H34 tergolong defisiensi sampai optimum, Blok I26 tergolong defisiensi sampai optimum, dan Blok J26 tergolong defisiensi sampai optimum. Pada masing-masing Blok di Rekomendasikan dosis pemupukan N, P dan K untuk blok G50 (1,73 kg urea/pohon/tahun, 1,50 kg Rock Phospate/pohon/tahun, dan 2,50 kg KCl/pohon/tahun). Blok H34 (3.00 kg urea/pohon/tahun, 3,50 kg Rock Phospate/pohon/tahun, dan 3,50 kg KCl/pohon/tahun). Blok I26 (1,73 kg urea/pohon/tahun, 1,50 kg Rock Phospate/pohon/tahun, dan 2,50 kg KCl/pohon/tahun). Blok J26 (3,00 kg urea/pohon/tahun, 3,50 kg Rock Phospate/pohon/tahun, dan 3.50 KCl/pohon/tahun). Dosis rekomendasi digunakan untuk meningkatkan produksi tanaman Kelapa Sawit di PT. Peniti Sungai Purun.Kata Kunci : Kadar Hara, Rekomendasi Pemupukan

Abstract

This research was aimed to identify the physical properties of land which includes the level of maturity and the thickness of peat, soil color, texture, structure, consistency, drainage, groundwater depth, soil effective depth, the depth of sulfidik, and the maturity of soil (n-value) as well as recommending the management of soil to support the development maize on peat land. The research was carried out in the Rasau Jaya III area Kubu Raya Regency, with an area of 2,490 Ha. The Soil physical analysis done in the laboratory of Soil Physics and Conservation the Faculty of Agriculture Tanjungpura University.

Abstract

Cadmium is a heavy metal and non-essential element but easily absorbed by plants and transferred to the shoots. Cadmium accumulation in various plant species showed varying responses. This research aimed to study the availability of Cd, the toxicity symptoms and growth of three species of Brassicaceae (Brassica rapa var. parachinensis, Brassica rapa var. pekinensis, Brassica oleracea var. alboglabra) on Cd-contaminated peat soil. Contaminant Cd and soil were mixed in different dosages i.e. 2 mgkg-1 Cd, 4 mgkg-1 Cd, 8 mgkg-1 Cd, 16 mgkg-1 Cd and 32 mgkg-1 Cd and used to fill growth pot (5kg/pot). The results showed that the addition of Cd contaminant produces Exchangable-Cd in growth media on range 0.1477 mgkg-1 up to 2.8459 mgkg-1 and influenced fresh weight of shoot of crops used except Brassica oleracea var. alboglabra. Brassica oleracea var. alboglabra showed more tolerant to high Cd exposure, no symptoms of toxicity found so far, while Brassica rapa var. parachinensis and Brassica rapa var. pekinensis showed stunting and chlorosis symptoms as excess of Cd in growth media

Abstract

Nutrient levels is the process to determine the present nutrient content in tissue plant. Nutrient levels obtained through field survey and nutrient analysis in the laboratory. This research aims to determine levels of N, P and K as well as recommend the use of N, P, and K for oil palm plants so as to increase the production of palm oil. This research was conducted at PT. Peniti Sungai Purun, MempawahRegency. The analysis results showed that the levels of N, P, and K on all blocks belonging to deficiency until optimum. In each block, the dose recommend of fertilizer N, P, and K to block G50 (1,73 kg urea/tree/year, 1,50 kg Rock Phospate/tree/4 times/year, and 2,50 kg KCl/tree/year) Blocks H34 (3,00 kg urea/tree/year, 3,50 kg Rock Phospate/tree/year, and 3,50 kg KCl/tree/year). Block I26 (1,73 kg urea/tree/year, 1,50 kg Rock Phospate/tree/year, and 2,50 kg KCl/tree/year). Block J26 (3,00 kg urea/tree/year, 3,50 kg Rock Phospate/tree/ year, and 3,50 kg KCl/tree/year). This dosage recommendations are used to increase the production of oil palm plants in PT. Peniti Sungai Purun.Keywords : Nutrient levels, recommendation of fertilization .
