Pengaruh Pemberian Dosis Trichoderma SP dalam Bentuk Pelet pada Berbagai Media Terhadap Pertumbuhan dan Hasil Tanaman Sawi Caisim (Brassica Juncea L.)

Abstract

This study aims to determine the increase in productivity of caisim mustard plants by applying Tricoderma sp. pellets. with different ingredients and doses. This research was conducted at the Laboratory of Observation of Pests and Diseases of Food Crops and Horticulture, Jl. Tanggul-Lumajang, Tekoan, Tanggul Kulon, Kec. Tanggul, Jember Regency for the production of Trichoderma sp pellets, and the pellet experiment was carried out in the yard of the house on Jl. Whale 3 No. 5, Sempusari, Kaliwates District, Jember Regency uses polybags. The experiment started in October 2022 until December 2022. The experimental method used the basic factorial randomized block design 2 factors with 3 replications. The first factor is the provision of pellets from different materials which consist of 3 levels, namely P1, P2, P3. The second factor was giving different pellet doses consisting of 4 levels, namely D0, D1, D2, D3. The data obtained were analyzed using ANOVA analysis of variance and if there was a significant difference then a further test was carried out using Duncan's Multiple Range Test at the 5% level. The variables observed included plant height, number of leaves, leaf area, chlorophyll content, root volume, plant fresh weight and plant dry weight. The results showed that the interaction treatment between the type of pellet making material and pellet dosage had no significant effect on the growth and yield of caisim mustard plants in all observational variables. The pellet dose treatment had no significant effect on the growth and yield of caisim mustard plants, except for the variable fresh weight and dry weight of the plants which had a highly significant different effect. The treatment of the type of pellet making material had no significant effect on the growth and yield of caisim mustard plants in all observational variables
