Abstract

Rumput gandum atau wheatgrass (Triticum aestivum L.) merupakan tanaman gandum muda yang berasal dari benih gandum. Konsumen seringkali tidak dapat menghabiskan langsung benih gandum untuk dijadikan rumput gandum, sehingga benih gandum sisa harus disimpan yang akhirnya menyebabkan kemunduran kualitas rumput gandum. Tujuan penelitian ini adalah untuk mengetahui pengaruh suhu  penyimpanan benih dan konsentrasi nutrisi terhadap hasil dan kualitas wheatgrass secara hidroponik yang diperoleh dari benih pada dua kondisi suhu  penyimpanan selama empat bulan. Penelitian ini dilaksanakan di Laboratorium Teknologi Produksi Tanaman Pangan, Fakultas Pertanian Universitas Padjadjaran, Jatinangor. Percobaan menggunakan Rancangan Acak Lengkap (RAL) yang diberi enam perlakuan kombinasi suhu penyimpanan dengan konsentrasi nutrisi yang diulang lima kali. Perlakuan suhu penyimpanan terdiri dari suhu ruang (23-28°C) dan suhu rendah (5-6°C), sementara konsentrasi nutrisi AB mix yang digunakan sebagai perlakuan yaitu 0 ppm, 500 ppm, dan 1000 ppm. Hasil penelitian ini menunjukkan bahwa suhu penyimpanan dan penambahan nutrisi memberikan pengaruh terhadap  persentase daya kecambah, tinggi bibit, bobot segar pupus, bobot kering pupus, dan kandungan klorofil, namun tidak berpengaruh nyata terhadap jumlah daun. Penyimpanan benih pada suhu rendah dan penambahan AB mix 500 ppm menunjukkan peningkatan daya kecambah, tinggi bibit, bobot segar pupus, dan bobot kering pupus, serta kandungan klorofil wheatgrass dari benih dibandingkan perlakuan lainnya.

Abstract

Black rice (Oryza sativaL.) is a health-beneficial food crop. No studies have investigated the ideal agroecosystem for achieving black rice's highest growth and yield. This study aimed to contrast the physiological characteristics, growth, and yield of black rice plants within two distinct agroecosystems: wetland and dryland. The study was conducted in a controlled screen house situated at an elevation of 750 meters above sea level, with a C3 agroclimatological zone according to the Oldeman classification. The research was conducted in April – November 2020. The research used quantitative methods without an experimental design. Two populations of black rice were planted in two agroecosystem treatments, conditioned as wetland and dryland. Observations were made on physiological characters (chlorophyll content index and stomatal conductance), growth components (plant height, number of tillers, shoot root ratio, dry weight, and leaf area index), and yield components (number of productive tillers, panicle length, number of grains per panicle, percentage of filled grain, and weight of 1000 grains). The results revealed that black rice plants in dry land had better growth, but had worse in physiological characteristics, yield components, and yields than in wet land.ABSTRAKPadi hitam (Oryza sativa L.) merupakan satu dari banyak tanaman pangan yang memiliki manfaat untuk kesehatan. Penelitian mengenai agroekosistem yang optimal bagi pertumbuhan dan hasil tanaman padi hitam belum dilakukan hingga saat ini. Penelitian ini dilakukan dengan tujuan untuk mengetahui perbandingan fisiologi, pertumbuhan, dan hasil tanaman padi hitam pada dua agroekosistem, yaitu lahan basah dan lahan kering. Penelitian dilaksanakan dalam screen house pada ketinggian 750 m di atas permukaan laut dan merupakan zona agroklimatologi C3 berdasarkan klasifikasi Oldeman. Penelitian dilakukan pada bulan April – November 2020. Penelitian menggunakan metode kuantitatif tanpa rancangan percobaan. Dua populasi padi hitam ditanam pada dua perlakuan agroekosistem, dikondisikan sebagai lahan basah dan lahan kering. Pengamatan dilakukan pada karakter fisiologi (indeks kandungan klorofil dan konduktansi stomata), komponen pertumbuhan (tinggi tanaman, jumlah anakan, nisbah pupus akar, bobot kering tanaman, dan indeks luas daun), dan komponen hasil (jumlah anakan produktif, panjang malai, jumlah gabah per malai, persentase gabah isi, dan bobot 1000 butir gabah). Hasil penelitian mengungkapkan bahwa tanaman padi hitam di lahan kering menghasilkan pertumbuhan yang lebih baik, namun memiliki karakter fisiologi, komponen hasil, dan hasil yang lebih buruk daripada di lahan basah.

Abstract

Job's tears (Coix lacryma-jobi L.) is a carbohydrate source functional food crop that can be developed as a substitute for rice. This study aims to determine the best application frequency of phosphate (P) fertilizer and paclobutrazol for supporting the growth and yield of job's tears in both rainy and dry seasons. The research was conducted from November 2021 - November 2022 at the Ciparanje research station and Laboratory Centre Universitas Padjadjaran, Jatinangor, Sumedang. The experiment used a randomized block design (RBD) consisting of P fertilizer application frequency (once, twice, and thrice) and paclobutrazol application frequency (once, twice, and thrice) and three replications.. The best season was determined using the T-test. The results showed that there was no interaction between growth components and job's tears yield in both rainy and dry season planting. P fertilizer application had a significant effect on lateral branch per tiller in the rainy season and root-shoot ratio in the dry season. Paclobutrazol application had a significant effect on the number of tillers per plant and number of seeds per plant in the rainy season, and the lateral branch per tiller in the dry season. Planting in the rainy season had the best growth and yield components compared to the dry season.

Abstract

The balance between growth and crop yield can be manipulated by exploiting nutrient and retardant interactions. This study is aiming to assess the effects of various combinations of NPK 16-16-16 fertilizer in different doses, along with the application of multiple concentrations of paclobutrazol on the growth and yield of hanjeli. This experiment was carried out in the experimental field of Ciparanje, Faculty of Agriculture Universitas Padjadjaran, Jatinangor, Sumedang from February 2021 to August 2021. This research was conducted in a split-plot design with three replications. The main plot consisted of 200 kg ha-1, 250 kg ha-1, and 300 kg ha-1. The subplot consisted of 2000 ppm, 3000 ppm, and 4000 ppm. The results show that there were interaction effects between different doses of NPK fertilizer and paclobutrazol concentrations on plant height and 100-grain weight. The best combination came from the application of 200 kg/ha NPK fertilizer with 3000 ppm of paclobutrazol, which gave higher results in plant height and 200 kg/ha NPK fertilizer with 2000 ppm of paclobutrazol on 100-grain weight.

Abstract

This study aims to determine the best interaction of potassium (K) fertilizer dose and retardant concentration on the growth, yield, and seed quality of G0 potato grown in the medium land of Jantinangor. The experiment was conducted at Screen House Station Ciparanje, Jatinangor, Faculty of Agriculture Universitas Padjadjaran from November 2022  until January 2023 at an elevation of ± 685 meters above sea level. The experimental design used was the Factorial Randomized Block Design (RBD). The first factor was the K fertilizer dose including 50%, 100%, and 150%. The second was the retardant concentration including without retardant, 100 ppm paclobutrazol, 100 ppm prohexadione-Ca, and 150 ppm prohexadione-Ca. The experimental results showed that there was an interaction effect between the K dose and retardant concentration. The interaction effect of 150% K and 100 ppm prohexadione-Ca showed the highest percentage of L class seed tuber and the lowest tuber weight loss. Independently, 150% K improved growth rate, number of tubers (6.67 knol/plant), and weight of tubers (73.33 g/plant). Independently, 100 ppm paclobutrazol concentration increased the chlorophyll content index. 150 ppm prohexadione-Ca concentration suppressed leaf area and plant height but increased stomatal conductance, fast emergence shoot time, and shoot length. 100 ppm prohexadione-Ca concentration produced the highest number of tubers and the weight of tubers, i.e., 6.78 knol/plant and 74.33 g/plant, respectively.

Abstract

The demand for soybeans as one of cereal commodities increases every year, however, to meet the production and demand level is still challenging in Indonesia. One of the causes of low soybean production is stress during cultivation, lack of nutrients, or poor quality of soybean seeds. One solution is to increase seed protection by coating the seeds with an environmentally friendly biological seed coating. This study aims to obtain the best biological seed coating for increasing soybean seed viability, vigor, and yield. The research was conducted at the Faculty of Agriculture Experimental Station of Universitas Padjadjaran, Jatinangor from August to November 2021. Two sets of experimental design were employed in this study, a Completely Randomized Design for the viability and vigor parameters in laboratory, and a Randomized Block Design with four replications for evaluation of the yield components in the field. The experiment was carried out with a combination of soybean cultivar and biological seed coating. The cultivars used in this study were Anjasmoro cv. (yellow) and Detam-4 cv. (black) and the biological seed coatings were B. subtilis, Trichoderma sp., and Rhizobium sp. Post-hoc test after F-test used Least Significance Different (LSD) with a significant level of 5%. The results showed that the application of the three biological seed coatings was not significantly affect seed physiological traits. However, the seed coating treatments increased the number of seeds per plant and seed weight per plant in yellow soybeans. Meanwhile, the application of B. subtilis and Rhizobium sp. in black soybeans increased the number of seeds per plant and the weight of seeds per plant. The best biological seed coating in this experiment was B. subtilis.
