Abstract

Bawang merah (Allium ascalonicum L.) merupakan salah salah satu komoditas tanaman hortikultural yang banyak dikonsumsi manusia sebagai campuran bumbu masak. Rendahnya produktivitas bawang merah di Indonesia disebabkan oleh menurunnya kesuburan tanah karena aplikasi pupuk anorganik terus menerus dan penggunaan pupuk organik yang jarang dilakukan. Penelitian ini akan dilakukan mulai bulan desember 2020 hingga februari 2021 yang bertempat di Pendem, Junrejo, Batu, Jawa Timur. Penelitian menggunakan Rancangan Acak Kelompok Faktorial (RAKF) yang terdiri dari dua faktor dengan 3 ulangan. Faktor pertama yaitu pupuk kandang ayam (K) yaitu: K0 = Pupuk Kandang Ayam 0 t ha-1, K1 = Pupuk Kandang Ayam 10 t ha-1 dan K2 = Pupuk Kandang Ayam 20 t ha-1. Sedangkan faktor kedua yaitu pupuk anorganik (Nitrogen): N1 = 120 kg ha-1, N2 = 160 kg ha-1, N3 = 200 kg ha-1, N4 = 240 kg ha- 1 dan N5 = 280 kg ha-1. Analisis data menggunakan analysis of varian (ANOVA) dan pengujian menggunakan F tabel taraf 5%. Hasil penelitian ini menunjukan bahwa pupuk kandang ayam 20 t ha-1 dan pupuk anorganik (Nitrogen) dengan dosis 160 kg t ha-1 meningkatakan laju pertumbuhan tanaman (LPT) umur 28-14 hst sebesar 90,62% dibandingkan dengan pupuk kandang ayam 10 t ha-1 dan pupuk anorganik dengan dosis 160 kg t ha-1. Pupuk kandang ayam secara nyata meningkatkan panjang tanaman pada umur pengamatan 42 dan 56 HST, berat kering tanaman pada umur pengamatan 42 dan 56 HST, bobot berangkasan segar per rumpun (g), bobot berangkasan kering per rumpun (g), dan bobot umbi kering per rumpun (g), bobot kering (matahari) umbi (kg m2) dan hasil panen (t ha-1), namun tidak memberikan pengaruh terhadap komponen pertumbuhan tanaman bawang merah pada awal pengamatan. Pupuk anorganik secara nyata meningkatkan komponen pertumbuhan yaitu panjang tanaman, jumlah daun, jumlah anakan, berat kering tanaman pada akhir pengamatan dan bobot Berangkasan Kering (g rumpun-1) panen bawang merah

English Abstract

Shallots (Allium ascalonicum L.) is one of the horticultural plant commodities that is widely consumed by humans as a mixture of cooking spices. The low productivity of shallots in Indonesia is caused by the decline in soil fertility due to continuous application of inorganic fertilizers and the infrequent use of organic fertilizers. This research will be conducted from December 2020 to February 2021 at Pendem, Junrejo, Batu, East Java. The study used a factorial randomized block design (RAKF) consisting of two factors with 3 replications. The first factor is chicken manure (K), namely: K0 = Chicken Manure 0 t ha-1, K1 = Chicken Manure 10 t ha-1 and K2 = Chicken Manure 20 t ha-1. While the second factor is inorganic fertilizer (Nitrogen): N1 = 120 kg ha-1, N2 = 160 kg ha-1, N3 = 200 kg ha-1, N4 = 240 kg ha-1 and N5 = 280 kg ha-1. Data analysis using analysis of variance (ANOVA) and testing using F table 5% level. The results of this study showed that chicken manure 20 t ha-1 and inorganic fertilizer (Nitrogen) with a dose of 160 kg t ha-1 increased plant growth rate (PGR) aged 28-14 DAP by 90.62% compared to chicken manure 10 t ha-1 and inorganic fertilizer with a dose of 160 kg t ha-1. Chicken manure significantly increased plant length at 42 and 56 DAP, plant dry weight at 42 and 56 DAP, fresh root weight per clump (g), dry root weight per clump (g), and tuber dry weight per clump. Clumps (g), dry weight (sun) of tubers (kg m2) and yield (t ha-1), but did not affect the growth components of shallot plants at the beginning of the observation. Inorganic fertilizers significantly increased the growth components, namely plant length, number of leaves, number of tillers, plant dry weight at the end of the observation and dry weight (g clump-1) of shallot harvest
