Abstract

Upaya untuk meningkatkan produksi dan kualitas tanaman jagung manis dapat dilakukan dengan beberapa cara, salah satunya dengan cara pemupukan baik pupuk organik maupun pupuk kimia (anorganik). Kecenderungan penggunaan pupuk kimia secara berlebihan dapat menyebabkan pencemaran lingkungan, Tujuan penelitian ini untuk mengetahui pengaruh Trichoderma dan Kompos Ampas Tahu serta interaksinya terhadap Pertumbuhan dan Produksi Tanaman Jagung Manis (Zea mays L. Saccharata). Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor yang diteliti, yaitu Trichoderma (T) 4 taraf dan Kompos Ampas Tahu (A) 3 taraf yang terdiri dari 12 kombinasi dengan 3 ulangan dimana faktor pertama adalah Trichoderma (T) yang terdiri dari 4 taraf yaitu T0 = 0 g tanaman-1, T1 = 10 g tanaman-1, T2 = 20 g tanaman-1, T3 = 30 g tanaman-1. Faktor kedua adalah kompos ampas tahu (A) yang terdiri dari 3 taraf yaitu A0 = 0 kg  plot-1, A1 = 2 kg plot-1, A2 = 4 kg plot-1. Parameter yang diamati adalah tinggi tanaman (cm), Luas daun (cm2) dan berat tongkol berkelobot plot-1 (g). Hasil penelitian menunjukkan bahwa pemberian Trichoderma berpengaruh tidak nyata terhadap semua parameter. Pemberian kompos ampas tahu berpengaruh nyata terhadap tinggi tanaman dan berpengaruh sangat nyata terhadap luas daun pada umur 6 minggu setelah tanam, tetapi berpengaruh tidak nyata terhadap bobot tongkol per plot. Sedangkan interaksi perlakuan Trichoderma dan kompos ampas tahu berpengaruh tidak nyata terhadap semua parameter.

Abstract

Customers venerate the commercial fruit plant known as Guava Madu Deli Hijau, which provides superior benefits to guava in general. This research seeks to determine the influence of growing medium, immersion time in young coconut water, and their interactions on the development of Syzygium aqueum stalk cuttings. The investigation was conducted between March and June of 2023. This study used a factorial randomized block design with two examined variables and three iterations. The first component was the availability of planting media (M), which came in four levels: sand, peat moss, vermiculite, and soil M0 = control, M1 = soil + cocopeat, M2 = soil + compost, M3 = soil + burnt husks. The second factor was the soaking time of the shoot cuttings in young coconut water (A) which consisted of 3 levels, namely A0 = control, A1 = 90 minutes, A2 = 180 minutes. The results showed that the growing medium treatment had no influence on the proportion of surviving cuttings but had a substantial effect on plant height, number of leaves, number of branches, root volume, and root length. The amount of time spent immersed in young coconut water had an effect on the number of leaves, seedlings, root volume, and root length, but not on the proportion of cuts that developed or plant height. The interaction between different planting media and the period of immersion in juvenile coconut water had no influence on any of the characteristics measured.

Abstract

The purpose of this study is to analyze the effects of decomposition, eco-farming, and their interactions on the development and harvest of shallots (Allium ascalonicum L.).This research used a two-factor, three-cycle randomized factorial block design. Compost (K) application came first, and that was done on three different stages.: K0 = no treatment (control), K1, K2, and K3., K1 = 1.5 kg plot-1 and K2 = 3 kg plot-1. The second factor of Eco Farming (E) consists of 4 levels, namely E0 = no treatment (control), E1 = 1.5 ml L-1 of water, E2 = 3 ml L-1 of water and E3 = 4.5 ml L-1 of water. Parameters observed were plant height , number of tillers per clump and tuber weight per plot .The results showed that compost application significantly impacted plant height and tuber weight per plot, but not tillers per cluster. Eco-farming's inclusion has a highly significant effect on plant height, a noticeable effect on tuber weight per acre, but no discernible effect on tillers per cluster. None of the measured variables were affected significantly by the composting and sustainable agriculture interaction treatment.

Abstract

Pakcoy (Brassica rapa L.) is a vegetable plant belonging to the Brassicaceae family. This study aims to determine the application and interaction of liquid organic fertilizer (poc) onion skin on Pakcoy (Brassica rapa L.) plants. This investigation was conducted between February and April of 2022 at Jl. Eka Suka Gg. Eka Suka XI Gedung Johor Kecamatan Medan Johor Provinsia Sumatera Utara. This investigation utilized a Factorial Group Randomized Design with 2 studied factors and 3 replicates, where the first factor was Hen house (A) with 3 levels and the second factor was replicate A0 = no treatment (control), A1=1.5 kg plot-1, A2 = 3 kg plot-1. The second factor is the concentration of Liquid Organic Onion Skin fertilizer (B) consisting of 4 levels, namely B0 = without treatment (control), B1 = 50 ml L-1 water, B2 = 100 ml L-1 water, B3 = 150 ml L-1 water. As parameters, plant height (cm), number of leaves (strands), leaf length (cm), leaf breadth (cm), and fresh weight of plants per sample (g) and per plot (g) were measured. The results revealed that the use of poultry house had a significant effect on plant height, leaf number, leaf length, leaf width, the fresh weight of plants per sample, and the fresh weight of plants per plot. Shallot peel liquid organic fertilizer has a very real effect on leaf length and fresh weight of plants per sample, a real effect on plant height and leaf width, but no real effect on leaf number and fresh weight of plants per plot. The interaction of hen house and onion peel liquid organic fertilizer has a significant impact on leaf length, leaf width, and fresh weight per plot, but no effect on plant height, number of leaves, and fresh weight per sample

Abstract

Peanuts (Arachis hypogaea L.) are the second most important legume crop in Indonesia after soybeans. Providing Vermicompost and Petrobiofertil Biological Fertilizer can increase plant growth and production and can also improve the chemical and biological properties of the soil. This research aims to determine the response to the application of vermicompost fertilizer and petrobiofertile biological fertilizer and their interaction on the growth and production of peanuts (Arachis hypogaea L.). The research was carried out on the land of Karang Rejo Pasar I Village/Subdistrict, Stabat District, Langkat Regency, North Sumatra Province with an altitude of ± 25 meters above sea level. This research was conducted from April to July 2023. This research used a Factorial Randomized Block Design with 2 factors studied and 3 replications where the first factor was Vermicompost (K) with 3 levels, namely: K0 (Control), K1 (2 Kg/ plot), K2 (4 Kg/plot) and the second factor is Petrobiofertil Biological Fertilizer (H) which consists of 4 levels, namely: H0 (Control), H1 (12 g/plot), H2 (24 g/plot), H3 ( 36 g/plot). The parameters observed were plant height (cm), pod weight per plot (g), pod weight per sample plant (g), weight of 100 dry seeds per plot (g). The results of the research showed that the application of vermicompost fertilizer had a very significant effect on the observed parameters such as plant height, pod weight per plot, pod weight per sample plant. The application of Petrobiofertil Biological Fertilizer had a very significant effect on all observed parameters such as plant height, pod weight per plot, pod weight per sample plant, weight of 100 dry seeds per plot. Meanwhile, the interaction of Vermicompost and Petrobiofertil Biological Fertilizer only had a significant effect on the parameters of plant height and pod weight per plot
