Abstract

Kacang panjang merupakan komoditas hortikultura yang tumbuh menjalar dan banyak dimanfaatkan oleh masyarakat Indonesia sebagai sayuran yang dikonsumsi sehari hari karena nilai gizi yang cukup tinggi. Namun, hasil produksi tanaman kacang panjang di Indonesia masih rendah dibandingkan dengan negara-negara lain. Penyebab rendahnya produksi tanaman kacang panjang dan penurunannya dari tahun ke tahun meliputi teknik bertanam yang kurang optimal, keterbatasan pengetahuan petani dalam budidaya, penggunaan varietas lokal dengan produktivitas rendah, serta pemupukan yang tidak tepat sehingga produktivitas tanaman kacang panjang menjadi rendah. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi paclobutrazol dan dosis pupuk NPK terhadap pertumbuhan dan hasil tanaman kacang panjang. Penelitian dilakukan di Desa Dander, Kecamatan Dander, Kabupaten Bojonegoro, Jawa Timur, dari Desember 2023 hingga Maret 2024. Rancangan penelitian menggunakan Rancangan Petak Terbagi (RPT) dengan 2 faktor yang diulang sebanyak 3 kali. Faktor pertama adalah konsentrasi paclobutrazol (P) dengan 4 tingkat perlakuan: 0 ppm (P0), 125 ppm (P1), 150 ppm (P2), dan 175 ppm (P3). Sedangkan faktor kedua adalah dosis pupuk NPK (N) dengan 4 tingkat perlakuan: 300 kg/ha (N1), 350 kg/ha (N2), 400 kg/ha (N3), dan 450 kg/ha (N4). Hasil penelitian menunjukkan bahwa konsentrasi paclobutrazol berpengaruh signifikan terhadap panjang tanaman, jumlah daun, umur muncul bunga, jumlah bunga, berat polong total per tanaman, berat polong total per petak, berat polong per hektar, diameter polong, dan daya simpan. Sementara itu, dosis pupuk NPK berpengaruh signifikan terhadap panjang tanaman pada 42-63 HST, jumlah daun pada 21 HST, 35 HST, dan 42 HST dan diameter polong. Interaksi antara konsentrasi paclobutrazol dan dosis pupuk NPK yang paling optimal terjadi pada perlakuan dengan konsentrasi paclobutrazol 150 ppm dan dosis pupuk NPK 450 kg/ha, yang dapat meningkatkan diameter polong.

Abstract

This research aims to determine the effect of concentrations of Paklobutrazol and SP-36 fertilizer on the growth of peanut plants (Arachis hypogaea L.). This research was carried out in October 2023 – January 2024 at the Dsn Baban Barat Land in Blega Bangkalan, East Java. This research is a factorial experiment which was prepared using a Completely Randomized Design (CRD) with 3 replications. The first factor is the provision of Paklobutrazol ZPT and the second factor is using SP-36 fertilizer Factor I: Paclobutrazol (P) concentration which consists of 4 levels: P0 = 0 ppm, P1 = 100 ppm, P2 = 200 ppm, P3 = 300 ppm and Fakor II = SP-36 fertilizer dose consisting of 3 levels: S0 = 150 kg/ha, S1 = 200 kg/ha, S2 = 250 kg/ha. The parameters observed were plant height, number of leaves (strands), age at flower emergence, number of pods planted, number of filled and empty pods, weight of pods planted, weight of seeds planted. The research results showed that the Paklobutrazol concentration treatment gave a positive response to the specified parameters, including plant height, number of leaves (strands), age at flower emergence, number of pods planted, number of filled and empty pods, weight of pods planted, weight of seeds planted. The highest average yield of pod weight per plant was in the P1 concentration treatment, namely 100 ppm (33.78 gr). The Paklobutrazol concentration treatment also produced a very significant effect on seed weight per plant. The highest was in the P1 concentration treatment, namely 100 ppm 28.50 gr. The SP-36 fertilizer dose treatment had a significant effect on the number of pods, the weight of the pods planted and the weight of the seeds planted. However, the parameters of plant height, number of leaves (strands), age at flower emergence, number of filled and empty pods, had no real influence. The results of the combined data analysis from both gave a positive response to observations of the number of pods, the weight of the pods planted and the weight of the seeds planted.

Abstract

The aim of this study is to examine the influence of Indole Butyric Acid (IBA) concentration and planting media on the growth of grapevine cuttings (Vitis vinifera L.). The research was conducted from September to November 2023 at the Greenhouse Block E, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang. The treatments were arranged in a factorial design (4x3) using a completely randomized design with three replications. The first factor was IBA concentration with four treatments: 0 ppm (Control), 1000 ppm), 2000 ppm), and 3000 ppm. The second factor was planting media with three treatments: soil:sand (1:1), soil:sand husk charcoal (1:1:1), and soil:sand (1:1). The observation variables included the time of shoot emergence, shoot length, number of leaves, number of roots, root length, and root volume. The observation data were analyzed using analysis of variance (ANOVA) and further tested with Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results showed that the 3000 ppm IBA concentration treatment had a significantly higher effect compared to the 0 ppm, 1000 ppm, and 2000 ppm concentrations on the parameters of shoot emergence time, shoot length, number of leaves, number of roots, and root volume. The planting media treatment had a significant effect on the parameters of shoot emergence and shoot length. The soil:sand media was the most effective for the shoot length parameter. There was a significant interaction between IBA concentration treatment and planting media on the parameters of shoot length, number of leaves, and root length. The conclusion of this study is that the 3000 ppm IBA concentration had the best effect on all parameters. The soil:sand planting media had the best effect on shoot length, number of leaves, and root volume. The 3000 ppm IBA concentration in the soil:sand planting media was the most effective for shoot length and number of leaves.

Abstract

Pepper plant propagation generally uses stem cuttings. Choosing the maturity level of the cutting will determine the subsequent growth of the cutting, because the body parts of the plant contain different food reserves and endogenous auxin. The growth regulator Indole Acetic Acid is used to stimulate the growth of roots and shoots of cuttings. The research aims to determine the effect of the level of maturity of the cutting material and IAA concentration on the growth of pepper seedlings and to determine the effect of the interaction between the two treatments. Research was carried out in the Greenhouse and Plant Science Laboratory, Faculty of Agriculture, University of Lampung. The experimental design used a completely randomized design (RTS), homogeneity was tested with the Bartlett test, non-additivity was tested with the Tukey test. Analysis of variance and least significant difference test (LSL) were carried out at the 5% level. The research results concluded (1). Cuttings originating from the middle part grew faster, namely in sprouting shoots, length of cutting shoots, number of leaves, and dry weight, but there was no significant difference in the dry weight of cutting roots. (2). An IAA concentration of 500 ppm gave the best response to shoot sprouting, shoot length of cuttings, number of leaves, and root dry weight. (3). Cuttings originating from the middle section that were applied with IAA 500 ppm were the best combination in terms of shoot emergence, shoot length, number of leaves, and shoot dry weight. Key words: cuttings, indole acetic acid, black pepper
