Abstract

Bawang merah (Allium cepa var ascalonium L.) merupakan tanaman hortikultura yang banyak dibudidayakan oleh masyarakat Indonesia. Pemanfaatan lahan suboptimal sebagai lahan budidaya bawang merah bertujuan untuk meningkatkan area luasan panen dan produktivitas bawang merah yang mengalami fluktuasi hingga penurunan pada tahun 2022. Alternatif lahan suboptimal untuk budidaya bawang merah adalah pemanfaatan lahan kering dengan kondisi lengas lapang sebagai faktor pembatas utama. Upaya yang dapat dilakukan guna meningkatkan produktivitas lahan kering yaitu dengan pemanfaatan varietas unggul tahan kekeringan. Penelitian ini bertujuan untuk mengetahui pengaruh cekaman lengas tanah, jenis varietas, dan hubungan antara cekaman lengas tanah dengan jenis varietas terhadap pertumbuhan dan hasil bawang merah. Percobaan dilakukan dengan metode Rancangan Acak Lengkap (RAL) dua faktor yaitu kadar lengas tanah dan jenis varietas. Kadar lengas tanah terdiri dari 100% (L1); 75% (L2); and 50% (L3), sedangkan varietas bawang merah terdiri dari varietas Sanren (V1); varietas Lokananta (V2); dan varietas Maserati (V3). Varietas Maserati menunjukkan tinggi tanaman tertinggi yaitu 39,2 cm dengan jumlah daun yaitu 5,9 helai. Kadar lengas tanah 75% kapasitas lapang pada varietas Maserati memberikan jumlah daun terbanyak yaitu 8,33 helai. Produktivitas varietas Sanren sebesar 0,189 t ha-1, varietas Lokananta sebesar 0,2 t ha-1, dan varietas Maserati sebesar 0,222 t ha-1.

Abstract

Kedelai (Glycine max L.) merupakan komoditas strategis penghasil protein nabati, namun produktivitasnya sering terhambat oleh defisiensi nitrogen. Penelitian ini bertujuan mengevaluasi pengaruh pemberian Rhizobium sp. terhadap pertumbuhan dan produktivitas kedelai varietas Dering. Percobaan menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan tiga perlakuan dosis Rhizobium (0 mg, 5 mg, dan 10 mg per tanaman) dan lima ulangan. Hasil menunjukkan bahwa dosis 5 mg meningkatkan tinggi tanaman secara signifikan (81,28 cm), sedangkan dosis 10 mg meningkatkan jumlah daun (23,8 helai), cabang (2,8 cabang), dan polong (38 polong per tanaman). Analisis statistik (ANOVA pada taraf signifikansi 5%) mengonfirmasi perbedaan nyata antar perlakuan. Simbiosis Rhizobium-kedelai efektif mendukung fiksasi nitrogen dan mengurangi ketergantungan pada pupuk anorganik. Dosis 10 mg direkomendasikan untuk produktivitas optimal.

Abstract

Kemiri Village, Panti District, Jember Regency is one of the rice-producing villages but faces the problem of scarcity of subsidized fertilizers and ineffective management of agricultural waste. This needs to be overcome with simple but effective handling. This community service activity aims to empower farmers through the production of Local Microorganisms (MOL) and Plant Growth Promoting Rhizobacteria (PGPR) to increase rice productivity while supporting the potential of livestock in the village. The target partner in this activity is the Sidodadi farmer group consisting of 30 farmers. The implementation method includes training in making MOL and PGPR, applying PGPR to rice plants, and making silage as animal feed. The results of the activity show that the activities carried out related to the use of PGPR can help increase rice growth, improve yields, and reduce dependence on chemical fertilizers. In addition, making silage successfully processes green fodder into quality feed that supports food security for livestock in the village. In the future, this activity is expected to strengthen the sustainability of agricultural and livestock practices in Kemiri Village and improve the economy of farmers.

Abstract

This study evaluated the growth and yield of three soybean varieties in response to mycorrhizal dosage on coastal sandy soil in Purworejo Regency, Central Java, Indonesia. The experiment employed a Factorial Randomized Complete Block Design (RCBD) with Split-Plot analysis for growth variables. The first factor was soybean varieties–Grobogan (V1), Burangrang (V2) and Agro Mulyo (V3). The second factor was mycorrhizal dosages–0 g per plant (D1), 1 g per plant (D2) and 2 g per plant (D3). Each of the nine combinations was replicated three times. The observed variables ware Crop Growth Rate (CGR); Relative Growth Rate (RGR); Net Assimilation Rate (NAR); Chlorophyll a (Chl a); Chlorophyll b (Chl b); Harvest Index; Pods per Plant; Dry Weight of Seed per Plant (DSP); Dry Weight of Seed per Sample Area (DSS); Dry Weight of Seed per Hectare (DSH), and Protein Content (PC). Data were analyzed using Analysis of Variance (ANOVA), and significant differences were further examined using post hoc analysis by the Duncan Multiple Range Test (DMRT). The three soybean varieties showed differences in their CGR. The CGR at 59 days after planting showed variations among the three varieties. The most notable increase in CGR was observed in the Burangrang variety between 59 and 73 days after planting. Burangrang also produced the highest average number of pods per plant (67.71 pods), due to vigorous growth and optimal branching (1–2 branches per plant). However, the highest protein content at 42.88% was found in the Grobogan variety by 2 g per plant of mycorrhiza dosage.
