Penelitian ini bertujuan untuk 1) mengetahui pengaruh macam pupuk NZEO-SRPlus terhadap populasi dan intensitas serangan hama utama tanaman padi, dan 2) mengetahui pengaruh dosis pupuk N terhadap populasi dan intensitas serangan hama utama tanaman padi. Penelitian ini dilaksanakan di lahan milik petani Desa Purwosari, Kecamatan Baturraden Kabupaten Banyumas, dimulai dari bulan September hingga Desember 2020. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) pola faktorial yang terdiri dari dua faktor dengan 3 ulangan, sehingga ada 9 kombinasi perlakuan. Faktor pertama, yaitu macam pupuk NZEO-SR Plus, terdiri dari Urea, NZEO-SR Plus 1 % dan NZEO-SR Plus 3 %, kemudian faktor kedua, yaitu dosis pupuk N, terdiri dari 0 kg/ha, 100 kg/ha, dan 200 kg/ha. Variabel yang diamati, yaitu populasi dan intensitas serangan hama utama tanaman padi, pola sebaran hama padi, populasi predator, indeks keanekaragaman populasi, tinggi tanaman, jumlah anakan produktif, jumlah malai per rumpun, jumlah butir per malai, dan gabah kering panen (ton/ha). Hasil penelitian menunjukkan pupuk NZEOSR Plus 1 % menghasilkan rerata populasi terendah hama walang sangit (L. acuta) sebanyak 4,32 individu /rumpun dan intensitas hama beluk (S. incertulas) terkecil sebesar 14,09%, sedangkan pupuk NZEO-SR Plus 3 % menghasilkan intensitas hama sundep (S. incertulas) terkecil sebesar 7.91 %. Dosis pupuk N 100 kg/ha menghasilkan rerata populasi hama walang sangit (L. acuta) terendah sebanyak 4,65 individu per rumpun, intensitas serangan hama sundep terkecil sebesar 9.57 %, serta intensitas serangan hama beluk terkecil, sebesar 12.49 %.

This study aims to 1) determine the effect of NZEO-SRPlus fertilizer on the population and intensity of the main pests of rice plants, and 2) determine the effect of the dose of N fertilizer on the population and intensity of the main pests of rice plants. This research was carried out on land owned by farmers in Purwosari Village, Baturraden District, Banyumas Regency, starting from September to December 2020. This study used a factorial Completely Randomized Block Design (RAKL) consisting of two factors with 3 replications, so there were 9 treatment combinations. The first factor, namely the type of fertilizer NZEO-SR Plus, consisting of Urea, NZEO-SR Plus 1% and NZEO-SR Plus 3%, then the second factor, namely the dose of N fertilizer, consisting of 0 kg/ha, 100 kg/ha, and 200 kg/ha. The variables observed were the population and intensity of the main pests of rice, distribution patterns of rice pests, predator populations, population diversity index, plant height, number of productive tillers, number of panicles per clump, number of grains per panicle, and dry grain harvested (tons/clump). Ha). The results showed that 1% NZEOSR Plus fertilizer produced the lowest population mean of walang sangit (L. acuta) as much as 4.32 individuals/clump and the lowest pest intensity of outskirts (S. incertulas) was 14.09%, while NZEO-SR Plus 3 fertilizer % resulted in the lowest intensity of sundep (S. incertulas) at 7.91%. A dose of 100 kg/ha of N fertilizer resulted in the lowest average population of walang sangit (L. acuta) of 4.65 individuals per clump, the lowest intensity of sundep pest attack was 9.57%, and the lowest intensity of insect attack was 12.49%.
