Abstract

AbstractThe research was carried out in the greenhouse of the Faculty of Agriculture, Islamic University of North Sumatra. Gedung Johor Village, Medan Johor District, Medan City, North Sumatra Province with an altitude of ± 25 m above sea level. This research will be conducted from December 2018 to February 2019. The aim of this study was to determine the effect of hydrogel and water on the growth of shallots (Allium ascolanicum L ). The design used was a factorial Completely Randomized Design (CRD) which consisted of two factors, namely: the hydrogel administration factor consisted of 4 levels, namely: Control, 1 g/pot, 2 g/pot, 3 g/pot and the volume of water sprinkling consisted of 3 levels, namely: 125 ml/pot (0.25 soil water content field capacity), 250 ml/pot (0.5 soil water content field capacity), 500 ml/pot (soil water content field capacity). The results showed that water spray affected growth, namely on plant height and plant wet weight. The hydrogel did not affect growth, but the combination of water spray and hydrogel affected the growth of plant height, plant wet weight and efficiency of watering as much as 250 ml where plant height and plant wet weight of the 250 ml watering treatment and the 3 g hydrogel were not significantly different from the 500 ml watering treatment and 3 g hydrogel.

Abstract

Bawang merah merupakan salah satu komoditas sayuran unggulan yang sejak lama telah diusahakan oleh petani secara intensif. Penelitian bertujuan untuk mengetahui pengaruh penyiraman terhadap pengelolaan air oleh hidrogel pada pertumbuhan tanaman bawang merah. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Non Faktorial dengan perlakuan interval penyiraman air yang terdiri dari 4 taraf yaitu A0 (2 x 1hari), A1 (1 x 3hari), A2 (1 x 2hari) dan A3 (1 x 1hari). Parameter yang diamati adalah tinggi tanaman, jumlah daun, jumlah anakan dan berat umbi. Data dianalisis dengan analysis of varian (ANOVA) dan apabila terdapat pengaruh nyata maka dilakukan uji lanjut menggunakan uji jarak berganda Duncan pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa perlakuan interval penyiraman berpengaruh nyata terhadap adalah tinggi tanaman, jumlah daun, jumlah anakan dan berat umbi. Aplikasi hidrogel dapat menghemat penyiraman dari satu satu hari menjadi satu kali hari, namun tidak efektif dalam mengatasi genangan akibat suplai air yang berlebihan.

Abstract

This study aims to determine the effects of applying papaya liquid organic fertilizer and varying the timing of application on the growth and yield of soybean (Glycine max L.) plants in Ultisol soil. The study employed a factorial randomized block design with two studied factors: 1. The first factor is papaya liquid organic fertilizer (P), which has four treatment levels: P1 = 75 ml/polybag; P2 = 150 ml/polybag; P3 = 225 ml/polybag; and P4 = 300 ml/polybag. The second factor is application time (W), which consists of three treatment levels: The second factor is application time (W), consisting of three treatment levels: W1 = at planting; W2 = one week before planting; and W3 = two weeks before planting. The observed parameters are plant height, number of branches, number of pods per polybag and filled pod weight. The research results indicate that applying liquid organic papaya fertilizer significantly affects the number of branches, number of pods per polybag and filled pod weight. However, it had no significant effect on soybean plant height. The timing of the application treatment non significantly affected plant height, number of branches, number of pods per polibag, filled pod weight. The interaction between the application of liquid organic papaya fertilizer and application time did not significantly affect plant height, number of branches, number of pods per polybag and filled pod weight.

Abstract

The research was conducted in the greenhouse of the Faculty of Agriculture, Universitas Islam Sumatera Utara. The aim of this research is to know the effect of chicken manure and N fertilizer on growth and production of mustard pakcoy plant with parallon vertikultur system. The design of this study used a Completely Randomized Design (CRD) Factorial consisting of two factors and repeated three times. The first factor is the provision of chicken coop (A) which consists of 4 levels, namely: A0 = 0 g / parallon (Control); A1 = 1000 g / parallon; A2 = 2000 g / parallon; A3 = 3000 g / parallon. The second factor is N (N) fertilizer consisting of 4 levels, namely: N0 = 0 g / parallon (Control); N1 = 1.8g / plant; N2 = 3.7g / plant; N3 = 5.6g / plant. The results showed that chicken manure gave a very significant effect on all parameters observed. The provision of chicken manure has a very significant effect on the parameters of plant height, the number of leaves, the diameter of the cob. The results showed that N fertilizer gave very significant effect on the parameters of plant height, leaf number, diameter of cob. The interaction of chicken manure and N fertilizer gave a very real effect on the diameter of the hump. However, the effect is not significant on the parameters of plant height, number of leaves.

Abstract

Rubber is a key plantation commodity in Indonesia, serving as a significant source of non-oil and gas foreign exchange. However, rubber productivity remains low, largely due to inadequate cultivation technology and the impact of pests and diseases. One of the most economically significant diseases affecting rubber plants is deciduous disease caused by Colletotrichum gloeosporioides, which spreads through spores carried by wind and rain. This study was conducted at the Sungei Putih Rubber Research Institute, North Sumatra, from February to June 2019, at an elevation of ± 25 meters above sea level. A factorial randomized block design (RBD) with three replications was employed. The treatments included three types of endophytic fungi (E1, E2, E3) derived from different isolates of PB 260 rubber clones, and four application methods (M0, M1, M2, M3). The observed parameters included latent period, disease occurrence, and disease intensity. The results indicated that the E2M2 treatment, which combined the second endophytic fungus with metabolite application, was the most effective in controlling C. gloeosporioides deciduous disease. This combination resulted in the highest average latent period (3.67%), the lowest disease occurrence (0.03%), and the most effective reduction in disease intensity (17.67% after 12 days). The study demonstrates the potential of specific endophytic fungi and application methods in managing rubber plant diseases, offering insights for improving rubber productivity in Indonesia.

Abstract

Rats are significant pests in oil palm plantations, attacking nearly all growth stages of the plants and causing damage that adversely affects productivity, leading to substantial losses. The protozoan Sarcocystis sp. is a parasite that infects rats and, in sufficient quantities, can cause death in these hosts. This protozoan is naturally present in rats but typically in small amounts. This study aimed to determine the prevalence of sarcosporidiasis (the presence of Sarcocystis sp.) in several rat species inhabiting smallholder oil palm plantations in Deli Serdang Regency, North Sumatra. Rat sampling was conducted from June to August 2025 using baited traps. The captured rats were then identified and categorized by species, sex, and weight. Sarcocystis sp. infection was detected by observing the presence of 'milky white threads' in the muscles, particularly in the rats' legs. The data obtained were analyzed both descriptively and quantitatively. Results showed that two rat species were captured: Rattus argentiventer and Rattus tiomanicus. Only 29.4% of the captured rats tested positive for the protozoan, of which 63.3% were male and 36.7% were female. All rats testing positive for the protozoan belonged exclusively to the R. tiomanicus species
