Abstract

Optimal rice production is very important to meet national food needs amid a decline in harvest area and production yields. This study aims to analyze the influence of rice planting methods and genotype on the growth and yield of rice plants (Oryza sativa L.). The research was conducted on the Lampung State Polytechnic Experimental Land using a factorial Group Random Design (RAK) with two factors: the planting method (legowo row 2:1, planting distance 25x25 cm, and transplanter 2:1) and rice genotype (PTP 01, Inpari 24, Jeliteng, and Pandan Wangi) each method was repeated 3 times. The results of the study show that the interaction of planting methods and rice genotype has a significant effect on the growth and yield of rice plants. The combination of the 2:1 transplanter planting method and the Inpari 24 genotype gave the best results in terms of plant height (101.33 cm), number of saplings (29.33), number of productive saplings (25.00), and yield per hectare (12.48 tons/ha). The 2:1 transplanter planting method and the Inpari 24 genotype can be recommended as the best combination in increasing rice productivity.

Abstract

This study looks at how to use biofertilizers to help sweet corn grow and yield well in an organic farming environment. The biofertilizers used were Trichoderma sp. fungus, Paenibacillus polymyxa bacteria, and a combination of the two with manure. The research was arranged in a Randomized Group Design (RAK) with four treatments and five replications. The treatments were control, manure and Trichoderma sp., Trichoderma sp. and P. polymyxa, and P. polymyxa alone. Parameters observed included plant height, number of leaves, stem diameter, cob length, cob diameter, cob weight, and sweetness level. The results showed that the biofertilizer treatment did not affect the growth and yield of sweet corn. However, the P. polymyxa treatment produced the tallest plants. The biofertilizer treatment did not affect yield components. It was concluded that biofertilizers did not significantly increase sweet corn growth or yield in organic farming.

Abstract

The presence of weeds in paddy rice crops results in a decrease in yields. Appropriate weed control methods are needed as an effort to reduce potential production losses. The first step to find out the right way to control weeds is by identifying the dominance and diversity of existing weeds. This study aims was to determine the dominance and diversity of weeds in organic and conventional paddy fields. This research was conducted in organic and conventional paddy fields of Lampung State Polytechnic, Lampung Province from October to December 2022. Weeds were observed on the 0.5 m2 quadrant method with 10 replications. The data were analyszed to find the Summed Dominance Ratio (SDR) value to determine the dominant weed and the Shannon - Wiener index (H') value to determine weed diversity. The identification results showed there were 11 weed species in organic land and 7 weed species in conventional land. Broadleaf weeds were the most dominant weeds in both land areas, namely Monochoria vaginalis in organic rice fields and Spenochlea zeylanica in conventional rice fields. The results of the weed diversity index analysis showed that in both land areas fall into the category of moderate diversitywith the value of  2.31 in organic rice fields and 1.93 in conventional rice fields.

Abstract

The presence of weeds can result in a reduction in the productivity of rubber plants, necessitating the implementation of control measures. Among the various control methods, the use of herbicides derived from paraquat dichloride has been identified as a more effective and efficient approach in terms of cost and time. However, the application of weed control measures can lead to alterations in the structure and composition of weeds. The objective of this study was to ascertain the prevalence of weeds and the impact of paraquat dichloride herbicide on the composition of weeds in rubber plantations. This study employed a randomized group design with six treatments and four replications. The treatments consisted of doses of paraquat dichloride, including 310.5 g/ha (P1), 414 g/ha (P2), 496.8 g/ha (P3), 621 g/ha (P4), mechanical control (P5), and control (P6). The results demonstrated that paraquat dichloride herbicide was efficacious in the control of weeds with a rapid onset, yet exhibited a limited duration in comparison to crop-translocated herbicides. This was evidenced by the diversity of weed species dominance at SDR 4 WAA < 8 WAA < 12 WAA. The application of paraquat dichloride herbicide and mechanical control were found to induce alterations in weed composition.

Abstract

Pertanian berkelanjutan menjadi fokus penting dalam memenuhi kebutuhan pangan tanpa merusak lingkungan, terutama di Indonesia yang memiliki kontribusi sektor pertanian yang besar terhadap perekonomian pedesaan. Penelitian ini bertujuan untuk meninjau penerapan praktik pertanian berkelanjutan di SAGA Farm di Bogor dan Tani Organik Merapi Yogyakarta. Studi ini dilakukan pada bulan September-Oktober 2024 dengan menggunakan metode wawancara mendalam, observasi lapangan, analisis laboratorium, dan studi literatur. Hasil penelitian menunjukkan bahwa terdapat perbedaan dalam pengelolaan kesuburan lahan dan kandungan unsur hara tanah. SAGA Farm memiliki keunggulan dalam produksi pupuk organik secara teratur, sedangkan TOM unggul dalam keragaman tanaman refugia dan rotasi tanaman yang lebih bervariasi. Keduanya menunjukkan tingkat hara tanah yang mendukung produktivitas tanaman, dengan kandungan fosfor yang tinggi di TOM (616,35 ppm) dan kalium yang tinggi di SAGA Farm (4099,10 mg/kg). Praktik pertanian berkelanjutan yang diterapkan oleh SAGA Farm dan TOM berkontribusi dalam meningkatkan kesuburan tanah, mengurangi ketergantungan pada bahan kimia dan mendukung keanekaragaman hayati. Dari perspektif sosial-ekonomi, kedua lokasi tersebut memberdayakan masyarakat lokal dan menurunkan biaya produksi petani. Meskipun pendekatannya berbeda, praktik pertanian di SAGA Farm dan TOM memberikan manfaat ekologi dan sosial ekonomi yang signifikan, menjadikan pertanian berkelanjutan sebagai solusi strategis dalam menjaga keseimbangan ekologi.

Abstract

Bercak daun dan karat daun menjadi dua penyakit utama yang paling sering ditemukan pada tanaman kacang tanah. Trichoderma sp. digunakan sebagai alternatif pengendalian penyakit tersebut. Tujuan dari penelitian ini adalah untuk mengkaji efektivitas aplikasi agens hayati Trichoderma sp. dalam menekan intensitas serangan penyakit bercak daun dan karat daun pada sejumlah varietas kacang tanah. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial yang terdiri atas dua faktor, yaitu: Faktor I (varietas kacang tanah) terdiri dari Talam-1 (V1), Takar-2 (V2), Kelinci (V3), Katana-2 (V4), dan Jerapah (V5). Faktor II berupa perlakuan tanpa Trichoderma sp. (H0) dan perlakuan dengan pemberian Trichoderma sp. dosis 6,4 g/tanaman (H1). Trichoderma sp. diaplikasikan satu kali kemedia tanah dilubang tanam. Data dianalisis menggunakan ANOVA (Analysis of Variance) dan dilanjutkan dengan uji BNT 5%. Dari hasil analisis yang telah dilakukan, dapat disimpulkan bahwa perbedaan yang terjadi tidak menunjukkan signifikansi secara statistik antar varietas (V1–V5) maupun antar perlakuan (H0 dan H1). Pada penyakit bercak daun, nilai intensitas berkisar antara 0,43 hingga 0,64, sementara pada karat daun berkisar antara 0,22 hingga 0,52.
