Abstract

The Annonaceae family exhibited a high level of diversity and is spread over many regions. The designation of the names of several species of the Annonaceae family varies in each region.  Therefore, characterization is needed to confirm and classify the taxonomy position of the species. This study aims to characterize the variation and analyze the clustering pattern of several species of the Annonaceae based on vegetative morphology characters. The type of method used in this research is exploratory descriptive, with seventeen specimen species consisting of ten Annonaceae studied in this research. Characters observed include tree age, stem diameter, plant height, stem color, type of sapling, type of branching, leaf shape, leaf tip shape, leaf base shape, leaf width, leaf length, leaf thickness, petiole length and thickness, leaf hairs , color of young and mature leaves, type of leaf edge, number of leaf veins, color of young branches, leaf hairs on young branches, and number of nodes on the stem per meter. These qualitative and quantitative characters were observed using Descriptors for Cherimoya (Annona cherimola Mill.) from Bioversity International and CHERLA. Data analysis was conducted in the Paleontological Statistics program with cluster analysis method (Bray-curtis similarity index) to produce a dendrogram topology. Results showed that there were variations in vegetative morphological characteristics among the ten species examined. Dendrogram topology was divided into 3 groups relatively following the tribe division, with similarity index 0.64 to 0.96. Xylopia sp. was separated from the others in Group 1 (Xylopiae). Group 2 (Uvariae) consisted of Fissistigma sp., Desmos chinensis, Artabotrys suaveolens, Uvaria purpurea, and Desmos sp. Group 3 (Annoneae) consisted of Annona muricata, Annona montana, Stelechocarpus burahol, and Annona glabra. Vegetative morphological characters have proven to be useful and effective in differentiating species in the Annonaceae family; it is recommended for initial identification of species, especially in the Annonoideae subfamily.

Abstract

Eggplant (Solanum melongena L.) is a favorable vegetable with high economic value. Its production is increased by using various growing media and liquid organic fertilizers (LOF) from household waste to produce organic products. This research aimed to study the interaction effect of the composition of the growing media and the dose of kitchen waste LOF on the growth and yield of eggplant. The experiment used a 3 x 3 factorial Completely Randomized Design (CRD) with three repetitions. The first factor was the composition of planting medium (M) consisting of 3 levels, namely: M1 (soil : cow manure), M2 (soil : cow manure : sand), and M3 (soil : cow manure : burned husk). The second factor was the dose of kitchen waste LOF (D) consisting of 3 levels, namely: D1 (0 cc/plant), D2 (10 cc/ plant), and D3 (20 cc/plant). The variables observed were plant height (cm), number of leaves (strands), stem diameter (mm), leaf area (cm2), number of branches, number of flowers (buds), and fruit production. The results of the observations were analyzed using Analysis of Variance (ANOVA). Once the results were significantly different, it would be continued with the Least Significant Difference (LSD) test at the 5% level. The results showed a significant interaction between the composition of the growing media and the dose of kitchen waste LOF on plant height at nine weeks after planting (WAP). Eggplant plant height at 3 WAP on the treatment of different planting media compositions had a significant effect, with leaf area at seven WAP, stem diameter at nine WAP, and number of branches at fourteen WAP. Treatment of kitchen waste LOF doses significantly affected the number of leaves and stem diameter of eggplant plants aged nine WAP. Terung (Solanum melongena L.) salah satu sayuran yang digemari masyarakat dan bernilai ekonomis cukup tinggi. Produksi terung ditingkatkan menggunakan media tanam beragam dan pupuk organik cair untuk menghasilkan produk organik. Tujuan dari penelitian adalah mempelajari pengaruh interaksi komposisi media tanam dan dosis POC sampah dapur terhadap pertumbuhan dan hasil tanaman terung. Percobaan menggunakan Rancangan Acak Lengkap (RAL) 2 faktor dengan pengulangan 3 kali. Faktor pertama adalah komposisi media tanam (M) terdiri atas 3 taraf, yaitu: tanah : pupuk kandang (M1); tanah : pupuk kandang : pasir (M2); dan tanah : pupuk kandang: arang sekam (M3). Faktor kedua adalah dosis POC sampah dapur (D) terdiri atas 3 taraf, yaitu: 0 cc/tan (D1), 10 cc/tan (D2) dan 20 cc/tan (D3). Variabel pengamatan adalah tinggi tanaman (cm), jumlah daun (helai), diameter batang (mm), luas daun (cm2 ), jumlah cabang, jumlah bunga (kuncup), dan produksi buah. Data pengamatan dianalisis menggunakan Analysis of Variance (ANOVA), dan apabila hasil berbeda nyata dilanjutkan uji beda nyata terkecil (BNT) taraf 5%. Hasil penelitian adalah terdapat interaksi yang nyata antara perlakuan komposisi media tanam dan dosis POC sampah dapur terhadap tinggi tanaman umur 9 MST. Tinggi tanaman terung umur 3 MST pada perlakuan komposisi media tanam yang berbeda memberikan pengaruh nyata, luas daun umur 7 MST, diameter batang umur 9 MST, dan jumlah cabang umur 14 MST.

Abstract

The composition of the growing medium and the application of moringa leaves liquid organic fertilizer (LOF) were investigated based on studies on the growth and yield of bok choy in Gondang Village, Plosoklaten District, Kediri Regency. The research was conducted for three months, from May to July 2022. The experiment was carried out in a factorial complete randomized design. The first treatment, namely: the composition of the planting medium, consisted of 3 levels with a ratio of soil to burned husk, respectively: 50, 30, and 10%. The second treatment consisted of LOF concentrations of moringa leaves at three levels: 10, 15, and 20ml per litre of water. Parameters observed within the scope of bok choy growth were plant height, number of leaves, and leaf area, while yield parameters were represented by fresh plant weight. Observation data were processed and analyzed based on variance tests. If the treatment affected the outcome significantly, additional tests with an LSD of 5% were performed. The study showed no interaction effect of the treatment of the composition of the planting medium with the LOF concentration of moringa leaves on all research parameters. The impact of the treatment on the composition of the growing media has a separate effect on the parameters of the number of leaves, leaf area, and plant fresh weight. Treatment of 50% M1 planting media composition gave the best results for each parameter. Komposisi media tanam dan aplikasi pupuk organik cair pada daun kelor diteliti berdasarkan kajian pertumbuhan dan hasil tanaman sawi.

Abstract

The people in Indonesia widely know cauliflower plants. In addition to their delicious taste, they also contain a high nutritional value for various kinds of dishes, both in restaurants and families. The purpose of this study was to determine the appropriate dose of liquid organic fertilizer (LOF) in order to obtain maximum growth and production of cauliflower (Brassica olerasea var Botritis). The study was conducted at the greenhouse of the Agriculture Faculty of Kadiri University. The experimental design employed a Completely Randomized Design (CRD), which consisted of six treatments repeated four times with a level test using the 5% Least Significant Difference test. Based on the results of observations and data analysis, it was found that the LOF dose treatment had no significant effect on the parameters of the average plant height, the number of leaves, and leaf area at the age of 9 days after planting (DAP). However, there was a highly significant difference in the observations of the average plant height, number of leaves and leaf area at the age of 16, 23 and 30 DAP. The average plant height, number of leaves, and leaf area were the largest in the D3 treatment (LOF dose of 75ml/plant). The observation of root wet-weight, root dry-weight, plant wet-weight, plant dry-weight, flower wet-weight, and flower dry-weight on different LOF dose treatment showed a highly significant difference, and the highest average was in the D3 treatment (75ml/plant). For the observation of harvest index, various doses of LOF showed a highly significant difference, and the highest average was in treatment D2 (50 ml/plant). However, it was not significantly different from D4 (100 ml/plant).

Abstract

Cucumber is one of the important vegetable commodities that have high nutritional value and is alternative medicine. To increase the productivity of both plants and the land where plants are grown, organic fertilization is needed. Manure is an organic fertilizer to increase soil fertility so that plant growth increases. Giving different types of manure with different doses will result in different plant growth and development. The purpose of this study was to determine the effect of the interaction between the type and dose of manure treatment on the growth and production of cucumbers. This study is a factorial experiment with two factors, which were arranged according to a completely randomized design (CRD) and repeated 3 (three) times. The first factor is the type of manure consisting of 3 levels, namely: chicken manure (K1), cow manure (K2), and goat manure (K3). The second factor is the dose of manure which consists of 3 levels, namely: 10 tons/ha (D1), 15 tons/ha (D2), and 20 tons/ha (D3). Observational data were analyzed by analysis of variance to determine the effect of the treatment on the observed parameters. After knowing the effect of treatment on the observed parameters, it is continued with the Least Significant Difference (BNT) test at the 5% level if it is significantly different. The combination of types and doses of manure significantly affected plant height, number, and leaf area at the age of observation 21 and 28 DAP, number of fruits, and fruit production per plant. The combination of the type of manure and the dose of manures did not significantly affect the number of leaves at 14 days of age, fruit length, fruit diameter, and fruit weight. The combination of goat manure at a dose of 20 tons/ha resulted in the best growth and production of cucumbers.
