Abstract

Purpose: This research aims to analyze the effect of organic and inorganic fertilizer packages on the growth of Tejakula tangerine plants and changes in soil chemical properties after being given organic and inorganic fertilizer packages. Research methods: The method used in this research was a Randomized Block Design (RAK) with 1 (one) factor. The treatment tested was the fertilizer package dose (P), consisting of 3 levels, namely organic fertilizer/cow manure (Po), organic cow manure + 22.6 g Urea fertilizer + 4 g KCl fertilizer + Phonska Plus 15 fertilizer -15-15 dose 84 g (Ph), and organic cow manure fertilizer + Urea fertilizer dose 22.6 g, KCl fertilizer dose 4 g, Phonska Plus fertilizer 15-15-15 dose 84 g + mycorrhizal biofertilizer + liquid organic fertilizer (POC) probiotics (Pc). Each treatment was repeated 8 times to obtain 24 treatments. Findings: The response to the fertilizer package had a significant to very significant effect on plant growth, such as increasing plant height, increasing the number of primary branches, increasing stem diameter and number of leaves. The fertilizer package that gave the highest response to plant height, number of leaves, while the increase in stem diameter had the same effect. Primary branch augmentation is the most influential Ph package but is not significantly different from PC. The effect of fertilizer packages on changes in soil chemical properties is that pH is neutral, DHL is classified as low to very high, C-org is classified as high, N-tot is classified as medium, P-available and K-available is classified as very high. Implication: The effect of mixed organic, inorganic and biological fertilizers and probiotic POC provide the best response to plant growth and increase DHL in the soil.

Abstract

Padi gogo (Oryza sativa L. var. gogo) ialah sebuah varietas padi yang dapat ditanam pada lahan kering yang sumber airnya hanya mengandalkan curah hujan. Cekaman kekeringan pada budidaya padi gogo di lahan kering terjadi karena irigasi berbasis curah hujan dan adanya perubahan iklim secara global, curah hujan jatuhnya tidak menentu sehingga padi gogo yang ditanam sering kali mengalami kekeringan pada fase-fase kritis akibat kurangnya kadar air tanah. Penggunaan arang jerami padi bisa mendorong efektivitas pupuk, memasok unsur hara makro, meningkatkan kesuburan, serta memperbaiki karakteristik fisik tanah. Studi berikut menerapkan Susunan Acak Kelompok Faktorial dalam 2 faktor, faktor ke-1 tersusun atas “cekaman kekeringan 100% kapasitas lapang (C0), 80% kapasitas lapang (C1), 60% kapasitas lapang (C2), dan 40% kapasitas lapang (C3)”, faktor ke-2 terdiri dari dosis biochar jerami padi “0 ton/ha (D0), 5 ton/ha (D1), 10 ton/ha (D2), dan 15 ton/ha (D3)”. Variabel pengamatan terdiri dari tinggi tanaman, KAR daun, banyaknya anakan produktif, banyaknya gabah isi per malai, berat segar gabah per polybag, serat berat kering gabah per polybag. Perolehan studi memuktikkan bahwasannya pemberian perlakuan cekaman kekeringan amat mempengaruhi pertumbuhan serta perolehan tanaman padi gogo. Semakin besar perlakuan cekaman kekeringan yang diberikan akan menurunkan nilai masing-masing variabel pengamatan. Pemberian dosis biochar jerami padi pada kadar 10 ton/ha terbaik pada variabel kandungan air relatif daun senilai 77,12%, banyaknya gabah isi per malai 23,30 g, berat segar gabah per polybag sebesar 4,74 ton/ha, dan berat kering gabah per polybag sebesar 3,79 ton/ha
