Tanggap Pertumbuhan dan Hasil Tiga Varietas Kacang Hijau terhadap Lama Genangan

Abstract

The objective of this research was to determine growth and yield responses of three mungbean varieties to waterlogging duration. The experiment was conducted at a screenhouse of ILETRI, Malang, East Java, from October to December 2016 using Alfisol soil from Probolinggo, East Java. The experiment consisted of two factors that were laid out in a factorial randomized complete block design with three replications. The first factor was mungbean varieties, namely Sriti, Vima 1, and Vima 2. The second factor was waterlogging durations, namely 0, 2, 4, and 6 days. The waterlogging treatments started at 20 days after planting. Mungbean plants fertilized with 250 kg Phonska ha-1 at the time of planting. The results showed that waterlogging treatments had negative effects on growth of the three varieties, indicated by a reduction in stem dry weight and leaf dry weight of the plants. Sriti variety was tolerant to waterlogging, Vima 1 was moderate tolerant, and Vima 2 was sensitive.Keywords: Alfisol soil, Vigna radiata, waterlogging stress

Pengaruh Durasi Penggenangan terhadap Pertumbuhan Vegetatif dan Waktu Berbunga Cabai Merah Keriting Capsicum annum (L.) Varietas Jacko

“…Beberapa penelitian mendukung hasil dari penelitian ini terkait penurunan kandungan klorofil akibat cekaman genangan. Lestari et al (2019) melaporkan bahwa cekaman genangan dapat menurunkan kandungan klorofil pada tanaman kacang hijau. Cekaman genangan juga menurunkan kandungan pigmen fotosintesis pada tanaman Capsicum frutescens L. (Raras et al, 2021).…”

“…Pada tanaman jarak pagar juga dilaporkan terjadi peningkatan jumlah daun dan luas daun setelah fase pemulihan (Verma et al, 2014). Pertumbuhan akar dan daun juga terjadi pada tanaman kacang hijau setelah fase pemulihan (Lestari et al, 2019)…”
