Abstract

Organic farming has been advocated as a more environmentally sound and ecologically balanced alternative to the dominant agricultural model. This study compared the decomposition of plant biomass in organically and non-organically managed soil properties. The treatments consisted of   non-organic land (A) and organic land (B). Non-organic land used chemical fertilizers as the main fertilizer, and organic fertilizers were not always given. In organic land, all fertilizers given were organic fertilizers, and organic pesticides have been carried out over the last five years. The area of ??each land studied was approximately 1,000 m2 divided into five points diagonally. Observations were made on soil pH, organic C, total N, and P Bray, as well as the amount and weight of soil macrofauna. The decomposition rate of the dried Edamame soybean biomass in the soil was estimated using the litterbag method. A litterbag measuring 30 x 20 cm with a pore size of 2-3 mm was used for this study. Seventy grams of plant biomass were put into the litterbag and buried in the soil to a depth of 10-20 cm. Analysis of C and N contents in plant biomass was carried out before and after incubation in the soil. The results showed that soil chemical properties are better, and soil macrofauna is more abundant in organic than non-organic land. Soil fertility in organic land was characterized by a larger decomposition rate constant (k) and a faster decrease in C/N ratios. The decomposition rate constant (k) in organic soil was 0.171, and that in non-organic soil was 0.105.

Abstract

Composting organic waste is significantly gaining attention as a sustainable and environmentally friendly material. This is because the use of microorganisms or microbial consortia in the composting process can enhance the quality of compost. Therefore, this study aimed to examine the impact of microbial consortia on cow manure composting efficiency and nutrient content. The experiment was conducted at the Polinela Organic Farm, Department of Food Crop Cultivation. A randomized block design was used with multiple treatments combining fresh cow manure and microbial inoculants, including catalyst, Bacillus, and Trichoderma. The parameters evaluated were the effects of water content, pH, temperature fluctuations, and macronutrient levels on composting, including nitrogen, phosphorus, and potassium. The results showed that microbial consortia significantly improved composting parameters such as moisture retention and temperature as a function of higher doses?of the inoculum. The highest total nitrogen (3.6%) and potassium (1.67%) content were obtained from Trichoderma treatment,?while the highest phosphorus (0.47%) content was obtained from Bacillus treatment. This?implied that microbial consortia could improve the quality and availability of composted nutrients in addition to the effectiveness of agricultural waste management and soil fertility practices. However, more research should be conducted?to determine the optimal microbial mixtures for various conditions of composting and the quality of the best compost produced.

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

Soil fertility is a key factor in agricultural success; however, poor soil quality often hindersproductivity. One solution is the use of soil amendments to improve soil's physical, chemical,and biological properties. This study aims to analyze research trends on soil amendments inIndonesia based on agricultural journals from 2015 to 2024. Data were collected throughGoogle Scholar, with a total of 24 articles analyzed based on publication count, research design,indicator plants, treatments, and data analysis methods used. The analysis results indicatefluctuations in research trends, with the highest number of publications in 2021 and 2022. The Factorial Randomized Block Design was the most commonly used method, while the mostfrequently studied indicator plants were soybean, rice, and maize. The most common treatmentinvolved combining soil amendments with organic and inorganic fertilizers. The dominant dataanalysis method was ANOVA, followed by post hoc tests such as LSD and Tukey HSD todetermine significant differences between treatment groups. This study recommends furtherresearch on the effectiveness of soil amendments in supporting sustainable agriculture andexploring their use across various plant species and environmental conditions.

Abstract

Lahan organik memiliki ketersediaan nutrisi yang berbeda dengan lahan konvensional, karena praktik pemupukan yang kurang, sehingga cekaman unsur hara terjadi ketika tanaman tidak mendapatkan cukup nutrisi yang diperlukan. Faktor-faktor seperti keberadaan bahan organik, dekomposisi, topografi, dan struktur tanah mempengaruhi ketersediaan unsur hara bagi tanaman. Tanaman jagung merupakan salah satu tanaman yang sensitif terhadap kekurangan unsur hara. Oleh karena itu perlu dilakukan penilaian untuk mengetahui pengaruh cekaman unsur hara di lahan organik terhadap pertumbuhan tanaman jagung dan varietas jagung yang mampu bertahan terhadap cekaman tersebut. Penelitian dilakukan di lahan organik Polinela Organic Farm pada bulan September hingga Desember 2023. Varietas jagung yang  digunakan dalam penelitian ini, yaitu varietas F1 jagung putih Arumba dan varietas F1 jagung manis Exotic Pertiwi. Parameter pengamatannya antara lain tinggi tanaman, jumlah daun, leaf area index, waktu bunga jantan keluar, bobot batang basah, dan bobot batang kering. Analisis data hasil penelitian menggunakan Rancangan Acak Kelompok (RAK) dan Uji T-Test. Hasil menunjukkan tidak ada perbedaan signifikan antara kedua varietas pada parameter jumlah daun, leaf area index, bobot batang basah, dan bobot batang kering, kecuali pada tinggi tanaman dan munculnya bunga jantan memiliki perbedaan yang signifikan. Rata-rata tinggi tanaman varietas F1 jagung putih Arumba sebesar 148,75 cm, sedangkan varietas F1 jagung manis Exsotic Pertiwi sebesar 111,3 cm. Sedangkan  rata-rata waktu  muncul bunga jantan varietas F1 jagung putih Arumba lebih cepat yaitu 45,5 hari. Sedangkan rata-rata varietas F1 jagung manis exsotic pertiwi 51,3 hari.

Abstract

The objectives of this study were to determine whether the application of kasgot organic fertilizer can increase the growth and yield of edamame, determine whether the effectiveness of kasgot organic fertilizer is better than non-kasgot organic fertilizer, and determine the best combination of kasgot organic fertilizer and non-kasgot organic fertilizer in increasing the growth and yield of soybeans. The treatments used: no organic fertilizer (control) (P0), non kasgot solid organic fertilizer (P1), non kasgot liquid organic fertilizer (P2), kasgot solid organic fertilizer (P3), kasgot liquid organic fertilizer (P4), non kasgot solid and liquid organic fertilizer (P5), kasgot solid and liquid organic fertilizer (P6), and non kasgot organic fertilizer and kasgot organic fertilizer (P7). The research findings indicate that the application of organic fertilizer enhances the growth and yield of soybeans compared to the control. Specifically, the combination of solid kasgot organic fertilizer (5 t ha-1) with liquid kasgot (50 ml L-1 water) produced the best plant growth and number of pods plant-1. It was also reported that the variables of number of branches, plant height, and plant wet weight significantly positively correlate with the number of pods plant-1.

Abstract

Determining the harvest time of rice plants is one of the determining factors for the success of rice production. Calculation of harvest time can be done using the heat unit method. This study aims to calculate the accumulation of heat units of several rice genotypes (Oryza sativa L.) in organic and non-organic cultivation systems. This study was conducted in September-December 2023 at Polinela Organic Farm (POF), Lampung State Polytechnic (5°21'10"S 105°13'43"E, 114 m above sea level using a Randomized Complate Block Design (RCBD) with four rice genotypes (PTP 01, Inpari 24, Jaliteng, and Pandan Wangi), which were planted in two different cultivation systems and replicated three times. The results showed that the four rice genotypes used showed significant differences in the accumulation of heat units between organic and non-organic cultivation systems. Organic cultivation systems require a higher average heat unit (1193.1°C days) than non-organic systems (1146.3°C days). Organic cultivation systems provide more stable growth in grain weight per panicle, the number of filled grains per panicle, and fewer empty grains. This demonstrates the importance of genotype selection and cultivation system in optimizing production and harvest time.
