Nunik Eka Diana, Sujak Sujak, Djumali Djumali

Abstract


Peningkatan produktivitas tebu diantaranya dapat dilakukan dengan pemupukan yang tepat. Penggunaan pupuk majemuk masih belum banyak digunakan pada tanaman tebu. Penelitian bertujuan untuk mengevaluasi efektivitas pupuk majemuk NPK terhadap produktivitas tebu dan pendapatan petani dilakukan di Desa Pakiskembar, Kecamatan Pakis, Kabupaten Malang pada November 2014 sampai dengan Oktober 2015. Efektivitas aplikasi pupuk majemuk (PM) dilakukan dengan menguji tujuh dosis pupuk yakni (1) PM 1 (100 N + 50 P2O5 + 60 K2O) kg/ha + pupuk tunggal (40 N) kg/ha, (2) PM 2 (120 N + 60 P2O5 + 72 K2O) kg/ha + pupuk tunggal (40 N) kg/ha, (3) PM 3(140 N + 70 P2O5 + 84 K2O) kg/ha + pupuk tunggal (40 N) kg/ha, (4) PM 4 (100 N + 50 P2O5 + 60 K2O) kg/ha + pupuk tunggal (60 N) kg/ha, (5) PM 5 (120 N + 60 P2O5 + 72 K2O) kg/ha + pupuk tunggal (60 N) kg/ha, (6) PM 6 (140 N + 70 P2O5 + 84 K2O) kg/ha + pupuk tunggal (60 N) kg/ha, dan (7) PM 7 (80 N + 40 P2O5 + 48 K2O) + pupuk tunggal (100 N) kg/ha, (8) PM 8 (60 N + 60 P2O5 + 60 K2O) + Pupuk tunggal 120 N kg/ha (pembanding) dan (9) tanpa dipupuk (kontrol).  Pengujian menggunakan Rancangan Acak Kelompok dan diulang empat kali. Pengamatan dilakukan pada parameter pertumbuhan dan produktivitas. Hasil penelitian menunjukkan bahwa dosis pupuk majemuk (140 N + 70 P2O5 + 84 K2O) kg/ha + pupuk tunggal (60 N) kg/ha menghasilkan efektivitas agronomis relatif (RAE) 144,27%, pendapatan bersih Rp.66.720.000,-/ha, nilai R/C ratio 1,84, dan peningkatan produktivitas tebu 36% lebih tinggi dibandingkan dengan aplikasi dosis pupuk pembanding.


Effectivity of compound fertilizer application on sugarcane productivity and
farmer’s


Increased productivity of sugarcane can be done through balanced fertilization. In this case, the usage of compound fertilizers is still not use widely on sugarcane crops. The research aims to evaluate the effectiveness of compound fertilizer N20P10K12 on sugarcane productivity and farmer’s income. The research was done in Pakiskembar; subdistrict Pakis, Malang in November 2014 to October 2015. Seven doses of N20P10K12 fertilizers namely (1) 100 N + 50 P + 60 K +40 N single fertilizer kg/ha, (2) 120 N + 60 P + 72 K + 40 N single fertilizer kg/ha, (3) 140 N + 70 P + 84 K + 40 N single fertilizer kg/ha, (4) 100 N + 50 P + 60 K + 60 N single fertilizer kg/ha, (5) 120 N + 60 P + 72 K + 60 N single fertilizer kg/ha, (6) 140 N + 70 P + 84 K + 60 N single fertilizer kg/ha, dan (7) 80 N + 40 P + 48 K + 100 N single fertilizer kg/ha, (8) 60 N + 60 P + 60 K + 120 N single fertilizer kg/ha (a standard fertilizer application) and control (without fertilization) arranged in a randomized block design and replicated four times. Observations were made on parameters of growth and productivity. The results showed that the fertilizer application with dose 140 N + 70 P + 84 K (compound fertilizer) + 60 N single fertilizer kg/ha gave reltive agronomic effectiveness (RAE) 144.27%, net income Rp. 66.72 million/ha, R/C 1.84, and increased productivity of sugarcane 36% higher than that of standard fertilizer application.
