| Abstract: | Penelitian ini bertujuan untuk menjelaskan respon pertumbuhan dan hasil
galur mutan padi Payo terhadap perlakuan dosis pupuk NPK. Penelitian
dilaksanakan di green house Badan Riset dan Inovasi Nasional (BRIN), Pasar
Jumat, Lebak Bulus, Jakarta Selatan pada bulan Maret-Agustus 2023. Percobaan
ini disusun menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) secara
faktorial, yaitu faktor genotipe dan dosis pupuk NPK. Perlakuan genotipe terdiri
atas 10 galur mutan padi Payo dan 2 varietas pembanding Induk Payo dan Inpari
32. Perlakuan dosis NPK terdiri dari tiga taraf yaitu 0%, 50% dan 100% dari dosis
anjuran 350 kg ha-1 . Hasil penelitian menunjukkan bahwa perlakuan genotipe
berpengaruh sangat nyata terhadap seluruh karakter yang diamati. Perlakuan dosis
pupuk NPK berpengaruh sangat nyata pada karakter tinggi tanaman, jumlah anakan
produktif, jumlah anakan total, jumlah gabah total permalai, gabah isi, gabah
hampa, bobot gabah per rumpun dan dugaan hasil. Interaksi antara perlakuan
genotipe dan dosis NPK berpengaruh sangat nyata hanya pada tinggi tanaman dan
jumlah anakan total. Perlakuan dosis pupuk NPK 50% dari anjuran tidak berbeda
nyata dengan dosis 100% untuk peubah komponen hasil jumlah gabah total, gabah
hampa, gabah isi, bobot gabah per rumpun dan dugaan hasil (produktivitas).
Seluruh galur yang diuji memiliki nilai dugaan hasil lebih tinggi dibandingkan
varietas pembanding payo dan Inpari-32. Galur PY-09 dan PY-10 mampu
berproduksi di atas 7 ton ha-1 dengan nilai dugaan hasil masing-masing 7,34
ton ha-1 dan 7,29 ton ha-1. Seluruh galur mutan padi Payo, terutama PY-09 dan PY 10, perlu dikembangkan lebih lanjut sebagai varietas unggul untuk pertanian
organik yang adaptif terhadap input rendah pupuk NPK. This study aimed to determine the growth response and yield of the Payo rice mutant lines to the treatment of NPK doses. The study was carried out in the green house of the National Research and Innovation Agency (BRIN), Pasar Jumat, Lebak Bulus, South Jakarta in March-August 2023. The experiment was arranged using a Randomized Complete Block Design (RCBD) with 2 factors, namely genotype and dose NPK. The genotype treatment consisted of 10 Payo rice mutant lines and 2 check varieties, Payo and Inpari 32. The NPK doses consisted of three levels, namely 0%, 50% and 100% of the recommended dose of 350 kg NPK/ha. The results showed that the treatment of genotype had a very significant effect on all of characters observed. The treatment of NPK dosage had a very significant effect on plant height, number of productive tillers, total tiller number, total grain number per panicle, filled grain, empty grain, grain weight per clump and estimated yield. The interaction between genotype and NPK dosage had a very significant effect on plant height and total number of tillers. The 50% recommended dose of NPK was not significantly different from the 100% dose for the total amount of grain, empty grain, filled grain, weight of grain per clump and estimated yield (productivity). All lines tested had higher estimated yield than the check varieties Payo and Inpari-32. The PY-09 and PY-10 lines were able to produce more than 7 tonnes/ha with estimated yields of 7.34 and 7.29 tonnes/ha. All Payo mutant lines, especially PY-09 and PY-10, need to be developed further as superior varieties for organic farming that are adaptive to low inputs of NPK fertilizer. |
