Abstract

Chili consumption in Indonesia has increased. Efforts to increase chili production need fertilization through roots and leaf fertilization. The research aimed to obtain optimum intervals of NPK (nitrogen, phosphor, potassium) fertilization and kinds of foliar fertilizer for the growth and yield of chili. The research was conducted from April to August 2020 in Gayam Village, Sukoharjo Regency, Central Java, Indonesia. This study used an experiential method with a Randomized Complete Block Design (RCBD) of 2 factors. The first factor was an interval of NPK fertilization (16-16-16) with a concentration of 25 g.L-1 with a dose of 240 mL.plant-1. The interval of NPK fertilization consists of 4 levels, NPK fertilizer which was applied every 5, 10, 15, and 21 days. The second factor was foliar fertilizer which consists of A foliar fertilizer, B foliar fertilizer, and C foliar fertilizer. The results showed that the interval of NPK fertilizer affected the number of dichotomous branches, dry stove weight, cumulative fruit, cumulative fruit weight, and fruit length at 1st harvest. NPK fertilization every 15 days increased the dichotomous branches by 23.16%, dry stove weight by 37.98%, cumulative fruits by 37.41%, and cumulative fruit weight by 41.46%. B foliar fertilizer and A foliar fertilizer gave the same performance in dichotomous branches. There was no interaction effect between the interval of NPK fertilization and the kind of foliar fertilizer on all growth and yield variables. NPK fertilization optimum intervals as supplementary fertilizers should be given every 15 days. This research can be used as a reference for farmers in fertilizing chilies.

Abstract

The productivity of red ginger in Indonesia has decreased by 9,174 tons compared to 2017. The decrease is due to the very limited area of red ginger production, the method of red ginger cultivation, which is still very conventional, and the low amount of organic matter in the soil. This study examines the effect of planting media composition on the growth and production of red ginger. The study used a Completely Randomized Block Design (RCBD) with six treatments, namely control (soil without manure), cow manure: green manure: soil (1:1:1), P2 = goat manure: green manure: soil (1:1:1), green manure: soil (1:2), cow manure: soil (1:2), and goat manure: soil (1:2) and repeated four times. Composition media of goat manure: green fertilizer: soil with a ratio of 1:1:1 could increase the growth of red ginger in variable plant height, number of leaves in the clump, leaf area, and the weight of fresh stover with a yield of 52.7 cm; 10,75; 148,5; 2952.59 cm2; and 307.33 g. Composition of green fertilizer media: soil with a ratio of 1:2 could increase the weight of dry stover with a value of 39.32 g, and red ginger production includes fresh weight of rhizomes 111.32 g, storage weight of rhizomes 107.87 g, and rhizome volume 124.12 cm3.

Abstract

Cabai merupakan komoditas yang penting secara ekonomi bagi Kelompok Tani Sidoluhur dan Kelompok Wanita Tani Puteri Petani Mandiri di Desa Cabeyan, Kecamatan Bendosari, Kabupaten Sukoharjo. Minimnya pengetahuan petani tentang pengendalian OPT menyebabkan pertanaman cabai terkendala berbagai penyakit terutama virus kuning yang dapat menurunkan hasil hingga 100%. Akhir-akhir ini berkembang formulasi nanoteknologi yang dapat meningkatkan efektivitas pestisida nabati. Nanoteknologi pestisida adalah formulasi partikel nanopestisida yang meningkatkan kelarutan, tingkat disolusi, dan dispersi saat aplikasi sehingga meningkatkan efikasi pestisida. Salah satu jenisnya yaitu nanovirusida yang berfungsi menekan infeksi virus pada tanaman. Kegiatan pengabdian ini bertujuan memperkenalkan nanovirusida nabati untuk mengatasi masalah penyakit pada pertanaman cabai. Metode kegiatan berupa penyuluhan mengenai cara mengendalikan berbagai organisme pengganggu tanaman (OPT) pada cabai, pembuatan demplot pembibitan, serta pelatihan teknis budidaya cabai dengan nanovirusida nabati. Aplikasi nanovirusida di lahan cabai lokasi mitra terbukti efektif menurunkan intensitas penyakit kuning lebih dari 50% dibandingkan tanpa pengendalian. Hasil kegiatan yang diperoleh berupa peningkatan keterampilan petani pada pengendalian virus kuning dan serangga penularnya dengan nanovirusida.
