Husni, Julia (2019) Respon Tanaman Selada (Lactuca Sativa L.) Terhadap Pemberian Mulsa Dan Periode Penyiangan Gulma. Sarjana thesis, Universitas Brawijaya.
Abstract
Selada (Lactuca sativa L.) ialah salah satu komoditi sayuran hortikultura yang memiliki nilai ekonomi tinggi dan banyak di konsumsi masyarakat. Salah satu kendala yang sering terjadi di lapangan yang menyebabkan turunnya produktifitas selada adalah keberadaan gulma di lahan. Gulma dapat menurunkan kuantitas maupun kualitas produksi karena berkompetisi dalam mendapatkan kebutuhan pertumbuhan. Salah satu cara yang dapat digunakan untuk memanipulasi lingkungan tumbuh adalah dengan penggunaan mulsa dan penyiangan gulma. Penelitian bertujuan untuk mengetahui pengaruh mulsa jerami padi dalam hubungannya dengan periode penyiangan gulma pada tanaman selada. Penelitian dilaksanakan di kebun percobaan Jatimulyo Fakultas Pertanian Universitas Brawijaya Malang, Jawa Timur pada ketinggian antara 440-667 mdpl. Penelitian ini dimulai pada bulan Oktober – Desember 2017. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktorial yang terdiri dari dua factor. Faktor 1: Mulsa (M) Faktor 2 : Periode (P) Penyiangan Pengamatan pertumbuhan dilakukan secara destruktif serta analisis vegetasi gulma pada umur 14 hst,21 hst, 28 hst, 35 hst. Pengamatan dekstruktif, meliputi komponen pertumbuhan: tinggi tanaman, jumlah daun, indeks luas daun, bobot segar konsumsi, CGR (Crop Growh Rate), komponen gulma: berat kering gulma dan analisis vegetasi gulma dan komponen hasil: indeks luas daun, bobot segar konsumsi, bobot kering total tanaman. Hasil penelitian menunjukkan bahwa ukuran mulsa dan penyiangan yang dilakukan berpengaruh nyata pada beberapa komponen pengamatan pertumbuhan selada (tinggi tanaman dan jumlah daun) dan pengamatan gulma (bobot kering total gulma, dominansi gulma) namun tidak berpengaruh nyata terhadap komponen hasil produksi selada yang diamati (indeks luas daun, bobot segar konsumsi, dan bobot kering total).
English Abstract
Lettuce (Lactuca sativa L.) is a horticultural vegetable commodity that has high economic value and is widely consumed by the public. One obstacle that often occurs in the field that causes a decrease in lettuce productivity is the presence of weeds in the field. Weeds can reduce the quantity and quality of production because they compete in gaining growth needs. One method that can be used to manipulate the growing environment is by using mulch and weeding. The study aims to determine the effect of rice straw mulch in relation to weeding periods of weed in lettuce plants. The research was carried out in the Jatimulyo experimental garden, Faculty of Agriculture, Brawijaya University, Malang, East Java, at an altitude between 440-667 masl. This study began in October - December 2017. This study used a factorial randomized block design (RCBD) consisting of two factors. Factor 1: Mulch (M), Factor 2: Period (P) Weed weeding. Growth observation is done destructively and analysis weed vegetation at the age of 14, 21, 28, 35 day after plant. Decstructive observation, including growth components: plant height, number of leaves, leaf area index, consumption fresh weight, CGR (Crop Growh Rate), weed component: weed dry weight and weed vegetation analysis and yield components: leaf area index, fresh weight consumption, total dry weight of plants. The results showed that the size of mulch and weeding had a significant effect on several components of lettuce growth observation (plant height & number of leaves) and weed observations (total weed dry weight, weed dominance) but had no significant effect on the components of lettuce production observed (index leaf area, consumption fresh weight, and total dry weight)
