Abstract

The study was conducted to determine the effects of dosage and frequency of applying single fertilizers (N,P, K) and compound NPK fertilizers on total nitrogen (N-total) using lowland rice (Oryza sativa L.) grownin Inceptisols. The research was carried out in rice fields located in Ciparay, Jelekong Subdistrict, BaleendahDistrict, Bandung Regency. A Randomized Complete Block Design (RCBD) was employed, consisting of seventreatments with three replications: (1) Control, (2) Single NPK fertilizer (grade 123,75-36-50), Frequency3, (3) Compound NPK Pelangi fertilizer (grade 80-40-40), Frequency 3, (4) Single NPK fertilizer (grade 8040-40),Frequency 3, (5) Single NPK fertilizer (grade 123,75-36-50), Frequency 2, (6) Compound NPKPelangi fertilizer (grade 80-40-40), Frequency 2, and (7) Single NPK fertilizer (grade 80-40-40), Frequency2. The results indicated that, in general, fertilization applied twice yielded the highest N-total values.Meanwhile, fertilization applied three times resulted in higher available phosphorus (P-available) levels.However, differences in fertilization treatments did not significantly affect exchangeable potassium (K) inInceptisols.

Abstract

Arjasari merupakan daerah yang memiliki kondisi geografis yang mendukung masyarakatnya untuk berprofesi sebagai petani ubi dan jagung. Hal ini dibuktikan dengan tingginya produktivitas ubi dan jagung yang mampu menambahkan peluang pada pasar ekspor yang menjanjikan. Metode pelaksanaan yang digunakan pada program ini memakai metode wawancara secara langsung untuk merekap data dari hasil wawancara. Program ini mencakup kegiatan koordinasi dengan petani, persiapan pertanyaan, dan wawancara secara langsung. Hasil survei menunjukkan bahwa lahan jagung di desa Arjasari memiliki produktivitas lahan yang realtif rendah Petani jagung rata-rata memiliki kesulitan akses modal dan pasar¸. Sehingga petani masih tergantung kepada para tengkulak.
