Abstract

Glyphosate is a widely used herbicide in the world, including in Indonesia. Many studies have reported that the use of glyphosate is harmful to soil microorganisms and, few reports on the effect of glyphosate on the growth and yield of corn. This study investigated the growth and yield of sweet corn cultivated on Ultisols under the effect of Glyphosate application. This study used a completely randomized design with four treatments and three replications in the greenhouse from July to November 2022. The treatments were the volume of herbicide consisting of 0, 5, 6, and 7 L/ha (equivalent 0, 2.43, 2.91, 3.4 Kg glyphosate-isopropyl ammonium/ha). The height of corn with the treatment 5 L/ha before 50 DAS got the highest value among all treatments with statistical differences. The 5 L/ha treatment also gave the best weight on corncob and corn roots at harvest time. The yield in the treatment 5 L/ha was 8.72 tons/ha, which was higher than the other treatments with no herbicide application, 6 L/ha and 7 L/ha, that gave 7.82, 6.89, and 6.33 tons/ha, respectively. From the results of this study, we can conclude that glyphosate affects the yield of sweet corn, which tends to decrease when glyphosate is used more than 6 L/ha.

Abstract

Penelitian bertujuan untuk mengetahui pengaruh pupuk organik dan dolomit terhadap pertumbuhan Mucuna bracteata di tanah masam. Penelilitan ini dilakukan pada bulan Desember 2022 sampai dengan April 2023 dilaksanakan di kebun pendidikan dan penelitian (KP2), Institut Pertanian Stiper di Desa Maguwoharjo, Kecamatan Depok, Kabupaten Sleman, DIY. Pada ketinggian tempat 118 mdpl. Penelitian dengan metode percobaan yang menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 2 faktor. Faktor I dosis pupuk organik yang terdiri dari 5 aras dosis (%volume) atau perbandingan volume pupuk organik : tanah yaitu : 0 % atau 0:1, 20 % atau 1:4, 25 % atau 1:3, 33 % atau 1:2, dan 50 % atau 1:1. Faktor II adalah dosis dolomit yang terdiri dari 4 aras dosis, yaitu : 0, 10, 20, dan 30 g/polybag. Data hasil pengamatan disnalisis dengan Sidik ragam (Anova) pada jenjang nyata 5%, Perlakuan yang berpengaruh nyata diuji lanjut dengan DMRT 5%. Hasil penelitian menunjukkan bahwa pemberian pupuk organik dosis 0%, 20% ,25%, 33% dan 50% volume berpengaruh sama terhadap pertumbuhan dan nodulasi tanaman Mb. Pemberian dolomit dosis 0 g, 10 g, 20 g dan 30 g berpengaruh sama terhadap pertumbuhan dan nodulasi tanaman Mb.

Abstract

This study aims to determine the status of soil fertility and provide fertilization suggestions based on soil fertility status in four types of overflow in Pusaka Village, Tebas District, Sambas Regency. The method used in this research is a survey method. The research starts from November 18 2022 to December 5 2022 and until the presentation of the results. For each location, 5 sampling points were determined outside the reef and 5 sampling points outside the reef. The distance is 100 m between the 4 sample points at a depth of 0-30 cm. Composite soil samples are from 5 points on the citrus reef and outside the oranges so that the total number of soil samples taken is 8 samples. The results of the study showed Assessment of soil fertility status in Pusaka Village, Tebas District, Sambas Regency has low criteria. The available P nutrients in the soil at the study site were very high, so there was no need to apply P fertilization. The recommendations for fertilizing urea and KCl at the study site were A =171,52 kg/ha dan 295,73 kg/ha, lokasi B = 179,33 kg/ha dan 1.318,17 kg/ha, lokasi C = 168,72 kg/ha dan 215,67 kg/ha, lokasi D = 156,8 kg/ha

Abstract

Plants, water, and peat soil interact to form peatland ecosystems, which are composed of these three interrelated elements. The water balance of peatlands is significantly influenced by the capillarity of the peat soil. This study attempts to ascertain the impact of depth on applying subsurface water retention technology (SWRT) membrane on capillary action based on moisture of peat soil in different    land uses. A completely nested randomized design was utilized in this investigation to avoid bias of the different degree of decomposition between land uses. The type of land use—namely, shrubs (PL1) and agricultural land (PL2) was the first account. The position of the membrane (its depth), which was set at -20 cm (D1), -30 cm (D2), and -50 cm (D3) and in addition to a control treatment without membrane installation (D0), was the second account. Three times each experimental unit was repeated. The YL-100 soil moisture content sensor, which is powered by Arduino, presented the research results. Arduino can produce digital values with a range of 0 to 1023 by converting moisture values that were  output as analog signals into digital values using an analog to digital converter (ADC) with a resolution of 10 bits. The outcome revealed that soil moisture content increasing up to the peat soil layer of 5 to 10 cm until the fifth day of observation due to rainfall along our study that increased the flux of water flow into the peat soil.
