Abstract

Rice field management plays a crucial role in successfully increasing rice production. This research aims to assess the fertility status of rice fields situated at varying altitudes in Giri Village, Nagrak District, Sukabumi Regency. The research comprises three stages, which include: Field research, Laboratory research, encompassing the analysis of soil chemical properties. Data analysis, conducted both descriptively and quantitatively. Composite soil samples from rice fields were collected at three different elevations (top, middle, and bottom) at a depth of 1-20 cm in the surface layer of the rice field soil. Analysis of paddy soil samples involved measuring pH H2O using the electrometric method, total N, and cation exchange capacity (CEC) using the titrimetric method, potential K2O using the flame photometric method, potential P2O5 and organic C using the spectrophotometric method, K-dd and Na-dd using the flame photometric method, and Ca-dd and Mg-dd using the AAS method. Data obtained from soil analysis at different elevations were compared based on soil type for each observed parameter. The research results indicate that the evaluation of nutrient status is influenced by altitude. Land situated at lower elevations exhibits better soil fertility status, followed by land at the upper and middle elevations. Keywords: Altitude, Andisols, Erosion, Rice fields, Soil fertility.

Abstract

The content in banana peels, namely protein, calcium, phosphorus, magnesium, sodium, and sulfur, has the potential to be used as liquid organic fertilizer (LOF). This study aims to evaluate the application of various doses of LOF derived from kepok banana peel on the growth and production of okra plants. The experiment was carried out at the Experimental Garden of the Faculty of Agriculture, University of Muhammadiyah Jakarta, from March to July 2021. The experiment used a Randomized Group Design (RAK), with six treatments and four repeats. The treatments are P0 (inorganic fertilizer as a control), P1 (50 mL LOF), P2 (75 mL LOF), P3 (100 mL LOF), P4 (125 mL LOF), and P5 (150 mL LOF). The results showed that the application of kepok banana peel LOF did not affect the growth and production of okra plants compared to the application of inorganic fertilizers. The cause is the low nutrient content in LOF banana peel of kepok. Keywords: as liquid organic fertilizer, inorganic fertilizer, kepok, liquid organic fertilizer, okra

Abstract

Padi hitam (Oryza sativa L. indica) merupakan pangan lokal yang kaya antioksidan dan mengandung pigmen paling baik serta memiliki aroma dan rasa yang baik. Salah satu varietas padi hitam yang memiliki penampilan yang spesifik dan unik adalah varietas Jeliteng. Varietas ini memiliki potesi yang tinggi namun kemampuan untuk berproduksi masih rendah. Oleh karena itu dilakukan upaya untuk meningkatkan produksi dengan pupuk silika cair. Penelitian telah dilakukan pada tanah Jenis Andisol di Desa Cibunar, Kabupaten Garut, Jawa Barat. Penelitian disusun menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan 5 konsentrasi pupuk silika cair yang berbeda (0 ml/L air (kontrol), 5 ml/L air, 7,5 ml/L air, 10 ml/L air, dan 12,5 ml/L air). Masing-masing penelitian diulang 5 kali dan setiap satuan percobaan terdiri dari 3 tanaman sehinggan ada 75 tanaman. Pupuk silika cair diaplikasikan saat tanaman berumur 2 Minggu Setelah Tanam (MST), 4 MST. 6 MST dan 8 MST. Penelitian menunjukkan bahwa pemberian pupuk silika cair memberikan respons positif terhadap tinggi tanaman, jumlah anakan, panjang malai, dan jumlah gabah per malai namun tidak berbeda nyata diuji secara statistik. Penggunaan 10 ml/L air pupuk silika cair cenderung memberikan hasil yang lebih bagus dibandingkan dengan penggnaan konsentrasi lainnya baik pada parameter pertumbuhan maupun hasil tanaman. Pemberian pupuk silika cair dapat mempengaruhi pertumbuhan dan produksi tanaman padi hitam varietas Jeliteng dengan konsetrasi 10 ml/L air. Kata Kunci: Andisol; Padi Hitam; Silika Cair AbstractBlack rice (Oryza sativa L. indica) is a local food that is rich in antioxidants and contains the best pigments and has a good aroma and taste. One of the black rice varieties that has a specific and unique appearance is the Jeliteng variety. This variety has high potential but the ability to produce is still low. Therefore, efforts are being made to increase production with liquid silica fertilizer. Research was carried out on Andisol type soil in Cibunar Village, Garut Regency, West Java. The research was structured using a Randomized Complete Group Design (RKLT) with 5 different concentrations of liquid silica fertilizer (0 ml/L water (control), 5 ml/L water, 7.5 ml/L water, 10 ml/L water, and 12 .5 ml/L water). Each study was repeated 5 times and each experimental unit consisted of 3 plants so there were 75 plants. Liquid silica fertilizer is applied when the plants are 2 weeks after planting (MST), 4 WAP. 6 MST and 8 MST. Research shows that application of liquid silica fertilizer provides a positive response to plant height, number of tillers, panicle length, and number of grains per panicle but there is no significant difference in statistical tests. Using 10 ml/L of liquid silica fertilizer water tends to give better results compared to using other concentrations both on growth parameters and plant yields. Providing liquid silica fertilizer can influence the growth and production of black rice plants of the Jeliteng variety with a concentration of 10 ml/L of water.
