Variation of Plant Growth and Yield Based on Upland Rice on Dry Land in Maluku

Abstract

Upland rice-based cropping pattern is a form of multiple cropping including intercropping, sequential planting, and relay planting where upland rice as a base crop can be preceded and/or rotated with other food crops as a secondary crop. The research was aimed to provide recommendations for upland rice-based cropping pattern technology in dryland agroecosystems in Maluku that would be able to increase land productivity > 1.00 (MCI = Multiple Cropping Index > 100%) compared to existing cropping patterns. The study used a Randomized Block Design (RCBD) with four treatments and repeated five times (farmers as replications). Four treatments for upland rice-based planting pattern technology assemblies, namely: 1) Pattern-A (Farmer A Pattern); 2) Pattern-B (Farmer B Planting Pattern B); 3) Pattern C (Farmer Improvement Cropping Pattern); and 4) Pattern D (Introduced Plant Pattern). The results showed that upland rice was planted double (multiple cropping) through intercropping and/or sequential cropping, namely Improved Cropping Patterns (Pattern C = Upland Rice + Corn - Peanuts) and Introducing Cropping Patterns (Pattern D = Upland Rice + Corn/Cassava - Green Beans - Peanuts) can increase land productivity with a double-cropping index 1.35 - 1.80 (IPG = 135% - 180%) compared to upland rice grown in monoculture (Farming Patterns). Multiple cropping (Upland Rice + Corn/Cassava - Green Beans - Peanuts) can be recommended as Upland Rice-Based Planting Technology Package on dry land in Maluku, because it can increase land productivity> 1.00 with an MCI (Multiple Cropping Index) of 180%.

ABSTRAK

Pola Tanam berbasis padi gogo merupakan bentuk pola bertanam ganda meliputi tumpangsari, tumpang gilir (runtun) dan tanaman sisipan dimana padi gogo sebagai komoditi pokok (base crop) yang bisa didahului dan atau digilir dengan tanaman pangan lainnya sebagai komoditi ikutan (secondary crop). Tujuan dari penelitian ini adalah untuk mendapatan rekomendasi paket teknologi pola tanam berbasis padi gogo pada agroekosistem lahan kering di Maluku yang mampu meningkatan produktivitas lahan > 1.00 (IPG = Indeks Pertanaman Ganda >100 %) dibandingkan dengan pola tanam petani eksisting. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan empat macam perlakuan dan diulang lima kali (petani sebagai ulangan). Empat perlakukan rakitan teknologi pola tanam berbasis padi gogo, yaitu: 1) Pola-A (Pola Tanam Petani A); 2) Pola-B (Pola Tanam Petani B); 3) Pola C (Pola Tanam Petani Perbaikan); dan 4) Pola D (Pola Tanaman Introduksi). Hasil penelitian menunjukkan bahwa padi gogo ditanam secara ganda (multiple cropping) melalui tumpangsari dan atau tumpanggilir, yaitu Pola Tanam Petani Perbaikan (Pola C = Padi Gogo + Jagung - Kacang Tanah) dan Pola Tanam Introduksi (Pola D = Padi Gogo + Jagung/Ubikayu - Kacang Hijau - Kacang Tanah) dapat meningkatkan produktivitas lahan 1.35 – 1.80 (IPG = 135% - 180%) dibandingkan jika padi gogo ditanam secara monokultur (Pola Tanam Petani). Pola bertanam ganda (Padi Gogo+Jagung/Ubikayu - Kacang Hijau - Kacang Tanah) dapat direkomendasikan sebagai Paket Teknologi Pola Tanam Berbasis Padi Gogo pada lahan kering di Maluku, karena dapat meningkatkan produktivitas lahan >1.00 dengan nilai IPG (Indeks Pertanaman Ganda) 180%.
