Abstract

Celery is a plant that produces secondary metabolites, known as flavonoids, with distinctive taste and smell. Flavonoids are synthesized in leaves and mainly accumulate in vacuoles of cells. Water deficit is one of the abiotic stress factors that affect the increase of several amino acids as cofactors that form secondary metabolites. Moreover, nitrogen nutrients have an essential role in the formation of amino acids and chlorophyll. The research results show that the total fresh weight increased at around 450 g by applying 200 kg N ha-1 under 100% field capacity (FC). Consequently, there was an increase in fresh weight, followed by the biomass of celery, which was 1/15 of fresh weight. Meanwhile, the accumulated flavonoid concentration was higher at 50% field capacity and 100 kg N ha-1. Surprisingly, the content of proline and flavonoids in leaves of the same age had higher concentrations at 100 kg N ha-1 and 50% FC compared to the concentration of proline and flavonoids at 200 kg N ha-1 in the form of urea fertilizer, namely 0.25 µmol g-1 and 67.84 ppm, respectively. At 50% FC and 100 kg N ha-1, it is slightly higher on proline and flavonoids than the application of 100% FC and 200 kg N ha-1. The highest accumulation of phosphorus in leaves is interestingly at around 0.51 ppm at 50% FC, compared to the application of 100% FC at 100 and 200 kg N ha-1 half bellows at around 0.3.

Abstract

This study contributes to understanding ecological changes in land use following slash-and-burn land clearing. This study aimed to compare the richness and density of plant species and soil fertility in farmland cultivated for one year (1 Y), three years (3 Y), and five years (5 Y) after slash-and-burn, with the conditions in the secondary forest (SF) in Berau Regency of East Kalimantan. Understory plant taxon types, numbers, and soil organic matter were measured in each region using a series of nested plots. The size of each observation plot was 20 x 100 m. Data on understory vegetation composition was collected using 1 x 1 m mini plots at 20 sampling points and divided into five blocks, with a 10 m spacing between sampling points on each property. Understory vegetation species and cover percentage, litter cover percentage, open soil percentage, and soil fertility were measured for each observation plot. The results showed that the land cover percentage increased each year during the 5 years transition from secondary forest to farmland. Furthermore, within the 5 years, there was a change in understory species, particularly the presence of grasses and sedges at 3 and 5 years after the land use change. However, the transition from secondary forest to farmland within 5 years did not alter soil organic matter and total nitrogen.

Abstract

Mung bean production in Indonesia has experienced a decline was caused by the decline in agricultural land area. The planting area in Indonesia for mung bean in 2017 was 206.832 ha, then it decreased to 189.298 ha in 2021. The agroforestry planting pattern is an effort to increase mung bean production, which has decreased due to the reduction in agricultural land area. The aims of this research are to test the growth and yield of three varieties of mung bean that are suitable for planting under mahogany and teak stands using an agroforestry system. The research used combined randomized block design (RBD) Nested Design consisted of 2 treatments, namely types of stands (mahogany and teak stands) and mung bean varieties (Vima 5, Vimil 2, and Kutilang). The results showed that the dry weight of seeds of the varieties of Vima 5 (2.60 ku ha-1), Vimil 2 (1.69 ku ha-1), and Kutilang (2.54 ku ha-1) planted under teak stands had higher yield than under mahogany stands.

Abstract

Perkembangan pertanian konvensional memunculkan kekhawatiran akan keberlanjutan sistem pertanian akibat ketergantungan input luar yang mengganggu efisiensi dan efektivitas lahan. Konsep Complex Rice System (CRS) memberikan alternatif pilihan keberlanjutan dari aspek pengelolaan lahan yang lebih terpadu. Mengombinasikan tanaman padi dengan tanaman refugia sebagai tanaman pematang, azola sebagai penambat unsur N, ikan dan itik/bebek untuk pengendali organisme pengganggu tanaman di samping itu kami juga menghitung keuntungan finansial petani. Kami melakukan diseminasi melalui kegiatan pengabdian masyarakat kepada warga dusun Klitik desa wajik Kab. Lamongan di Gapoktan gemah ripah sejumlah 46 petani terlibat dengan luasan mencapai 30 ha dengan menerapkan sekolah lapangan yang dilangsungkan pada Juni-September 2022 di satu musim tanam padi. Kegiatan diawali Survei dan Diskusi Kelompok (FGD) dilakukan sebagai kegiatan awal untuk memahami konteks lokal sistem pertanian padi dan mempersiapkan implementasinya. Kemudian kegiatan CRS berlangsung di ladang petani, berukuran ±1000 m2 dan terdiri dari 2 pengulangan perawatan. Perawatan terdiri dari, monokultur padi dan CRS. Evaluasi terhadap kegiatan dilakukan dengan diskusi kelompok, dan evaluasi terdiri dari peningkatan antusiasme dan keuntungan dari CRS dengan menanam refugia dibanding monoculture. Hasil menunjukkan produktivitas petani yang menerapkan sistem CRS lebih tinggi dibanding produktivitas sebelumnya. Hasil FGD menunjukkan lebih dari 55% petani setuju mengembangkan CRS karena pendapatan yang diperoleh meningkat dan dapat memenuhi kebutuhan hidup petani.

Abstract

Sweet corn is recognized as one of the plants with relatively high economic value and potential for expansion, increasing from 8.31 to 18 million tons. Arranging planting distance and applying potassium when conditions are stressed by drought can be one of the efforts to modify the environment for plant growth.  This study employed a split-plot design repeated three times, consisting of a main plot and three levels of sub-plots. The main plot is J1 = 75 x 20 cm, J2 = 50 x 30 cm, and J3 = 60 x 25 cm. While the sub-plots are K1 = 100 kg.ha-1, K2 = 200 kg.ha-1, dan K3 = 300 kg.ha-1. The results obtained show that the arrangement of closer planting distances between rows 60 x 25 cm with increasing doses of Potassium 200 kg.ha-1 results in an interaction with increased growth and optimal sweet corn yields. The microclimate conditions of sweet corn, including soil moisture, were influenced by spacing and potassium dosage. The relationship between plant distance and potassium dosage to soil moisture is directly proportional or linear. Plant distance of 60 x 25 cm with increasing potassium dose, such as at a potassium dose of 300 kg.ha-1 produces the most moist soil moisture under drought stress conditions.
