“…(1) Dimana: Yt= hasil jagung pada pupuk yang diuji (ton.ha -1 ), Ys= hasil jagung standar (ton.ha -1 ), dan Yo= hasil jagung pada perlakuan kontrol (ton.ha -1 ). Semakin besar persentase RAE, maka semakin efektif pupuk terhadap sifatsifat agronomis secara relatif (Nurdin et al, 2020).…”

“…Pada umur 28 HST, pertambahan jumlah daun jagung pulut terbanyak dicapai pada pemberian PO sebanyak 500 kg.ha -1 dengan persentase sebesar 0,41% sedangkan terendah dicapai pada pemberian PO sebanyak 0 kg.ha -1 dengan persentase sebesar 0,36% saja. Pola ini relatif berbeda dengan hasil penelitian (Nurdin et al, 2020) yang melaporkan bahwa semakin tinggi dosis pupuk, maka jumlah daun juga semakin meningkat.…”

Jagung pulut menjadi sumber pangan lokal bagi masyarakat sehingga dapat mewujudkan ketahanan pangan, tetapi ketersediaannya masih rendah. Selain itu, budidaya jagung pulut selama ini masih bergantung pada pupuk anorganik yang berpotensi membahayakan kesehatan masyarakat. Tujuan penelitian ini adalah menganalisa pertumbuhan dan produksi jagung pulut, serta menentukan efektivitas agronomi dan ekonomi dengan pemberian pupuk organik di Desa Bualo, Kabupaten Boalemo. Data yang diperoleh dirancang dengan rancangan acak kelompok yang terdiri dari 11 perlakuan dan 3 ulangan, sehingga terdapat 33 satuan percobaan. Hasil penelitian menunjukkan bahwa pemberian pupuk organik sebanyak 2.000 kg.ha–1 mampu meningkatkan pertumbuhan dan produksi jagung pulut terbaik. Pupuk organik baik secara agronomis dan ekonomis tergolong efektif meningkatkan produksi jagung pulut.

“…Coarse material was rock fragments measuring in 2 mm of diameter or more which affected to soil moisture storage, infiltration, erosion, and land use [21]. Slopes had a significant effect on local maize production, in which the steeper the slopes, the lower the production would be [22]. Likeweise for the soil erosion the more erosion increases, the lower the production of maize would be [23].…”

Increase national maize production has not been followed by an increase in maize productivity per unit area because maize was grown on land that was not suitable with these land quality. This study aims to determine the land quality that control of local maize production. This research was conducted at the Gorontalo Regency. A total of 33 mapping units had been established containing data of soil properties, climate and terrain divided into land quality, as well as data of local maize production. A partial least square of structural equation models (PLS-SEM) analysis was used to determine the land quality and characteristics that control of local maize production through testing the validity and reliability of variables, as well as testing structural models. The results showed that the all manifest variables were valid and able to explain well the latent variables, except for texture, cation exchange capacity, and base saturation. Furthermore, the latent variables temperature, water availability, oxygen availability, nutrient retention, nutrients availability, sodicity, erosion hazard, flood hazard, and land preparation used has good composite reliability and high reliability because of the composite reliability and alpha cronbach >0.6, except for rooting media. Land quality that control of the local maize production were the oxygen availability (X1), rooting media (X2), nutrient retention (X3), nutrients availability (X4), erosion hazard (X5), and land preparation (X6) with the best equation: Y = 1.805 + 0.276X1 + 0.303X2 + 0.353X3 + 0.346X4 -0.337X5 -0.303X6. The land characteristics that control of the local maize production were drainage (X1), coarse material (X2), effective depth (X3), pH KCl (X4), C-organic (X5), total N (X6), available K (X7), slope (X8), soil erosion (X9), surface rock (X10) and rock outcrop (X11) with the best equation: Y = 2.447 + 0.187X1 -0.212X2 + 0.153X3 + 0.349X4 + 0.166X5 + 0.169X6 + 0.313X7 -0.352X8 -0.230X9 -0.237X10 -0.187X11.
