Abstract

The apple farming group is one of the built of Department of Plant Pests and Diseases, Agricultural Faculty, Brawijaya University. In 2019, this departmen received a request from apple farmers in Madiredo Village, Pujon District to held an assistance programs of apple cultivation and environmentally pest control. This is related with the increasing of fruit rot and other diseases which is caused a decrease of apple production especially in Malang Regency. In general, apple farmers still rely on disease control using chemical fungicides which can have a negative impact on the environment and create resistance to pathogenic fungi. Therefore, this research was carried out to explore and study the potential of biological agents in apple production centers in Malang Regency, specifically in Poncokusumo, Pujon, and Batu District on conventional fields and mixed fields. This research was held observationally through fields surveys and farmer interviews, took soil samples and disease samples then then isolating, identifying and testing for antagonism at laboratory. Based on interviews and observation of symptomology, two dominant diseases were found, namely fruit rot disease (Gloeosporium sp.) and marsonina leaf spot disease (Marssonina coronaria). The results of exploration of the rhizospheric apple plants obtained isolates on conventional fields in Kec. Pujon has the highest abundance of fungal colonies compared to other regions. Based on the results of the antagonism test for pathogenic fungi and biological agents, it was found that the isolate codes KH.C, KK.A, JK.B, JK.J, and BK.B had the highest percentage of inhibition or the most effective in controlling the pathogen Gloeosporium sp. So in the next, the species can be identified molecularly.

Abstract

Land in Tawangsari District, Sukoharjo Regency had a limiting factor in the form of water availability. One of the local commodities cultivated for generations on dry land in this region is gembili (Dioscorea sp.). However, the gembili cultivation process has not produced optimal productivity and is threatened with extinction. Therefore, gembili cultivation and use of dry land need to be optimized by carrying out integrated land management. The aim of utilizing dry land is to increase local food production and sustainability as alternative food and maintain national food security. This research was conducted using data on productivity, quantity and type of fertilizer obtained through interviews with gembili farmers and secondary data on soil types obtained from BPP Tawangsari District, Sukoharjo Regency. The results showed that grumusol and lithosol soil types had no significant effect (p > 0.05) on gembili productivity. Providing organic + inorganic fertilizer with giving organic fertilizer without a combination produced values that were not significantly different (p > 0.05). However, the average productivity results were sequentially from grumusol and lithosol (6.1 ton.ha-1 and 7.1 ton.ha-1). Meanwhile, the use of organic fertilizer is 8.06% higher compared to organic fertilizer + inorganic fertilizer. The results of the multiple regression test for organic fertilizer had a significant effect (p < 0.05) on the productivity of Dioscorea sp..

Abstract

ABSTRAKPola tanam dan perbedaan musim memberikan pengaruh pada keanekaragaman dinamika dan komposisi spesies tumbuhan bawah pada tanaman jati (Tectona grandis) yang merupakan tanaman deciduous. Penelitian ini bertujuan untuk mengetahui keragaman spesies, dinamika dan komposisi vegetasi tumbuhan bawah yang ada pada pola tanam agroforestri (AF) dan monoculture (MN) jati pada musim hujan (RS) dan musim kemarau (DS). Survei lapang telah dilaksanakan pada bulan Februari-Maret dan Juli-Agustus 2023 di kawasan hutan produksi jati Perum Perhutani Kecamatan Kalipare, Kabupaten Malang, Jawa Timur. Kami menggunakan frame ukuran 1 x 1 m dan meletakkannya secara sistematis. Total 117 petak diamati yang terbagi menjadi 27 petak untuk AF dan 90 petak untuk MN. Jarak antar Plot adalah 5 m yang di tandai posisinya dengan Global Positioning System (GPS) dan label penanda. Pada tiap plot dilakukan pengamatan dan di catat jenis spesies, persentase tutupan vegetasi serasah dan tanah terbuka serta menghitung Nilai Kesamaan Sorensen (IS). Adapun pengamatan faktor lingkungan meliputi faktor naungan (keterbukaan kanopi) dan air (curah hujan). Kami gunakan kamera hemisperical lens (Samsung gear 360°) yang diambil 1 m di atas titik petak kemudian dianalisis menggunakan GLA 2.0 untuk memperoleh keterbukaan canopy. Faktor curah hujan di peroleh dari data Stasiun klimatologi setempat. Hasil penelitian menunjukkan terdapat perbedaan spesies tumbuhan bawah di AF dan MN jati. Komposisi tumbuhan bawah MN meliputi 49 spesies dari 23 famili sedangkan di AF terdapat 35 spesies dari 16 famili. Vegetasi pada AF dan MN jati memiliki komposisi dan struktur yang berbeda. MN jati pada MK memiliki keragaman yang lebih tinggi dibanding pola tanaman AF karena AF di wilayah tersebut lebih mirip monokultur tanaman semusim yang intensif. Faktor keterbukaan kanopi dan curah hujan memiliki pengaruh signifikan terhadap tutupan vegetasi

Abstract

The development of hybrid sweet corn varieties involves the selection of parental lines with specific traits to ensure good yield potential. The selection of inbred lines of sweet corn is a critical aspect of breeding programs aimed at developing improved varieties. This research will provide useful information of sweet corn inbreed lines have the potential to be developed as parent lines in the development of hybrid varieties. The study utilized 24 inbred lines (G1-G24) of sweet corn and employed a Randomized Complete Block Design (RCBD). Data analysis involved the use of analysis of variance with a 5% significance level, path and dendrogram analysis. Based on the analysis of 24 inbreed line of sweet corn, the potential for selecting parents based on quantitative traits influencing the outcome is evident in inbreed line G18, G12, G4, G23, and G20. Identification of these potential parents is essential for the genetic improvement of the population. The correlation heatmap data indicates a 41% correlation between the number of rows and cob stag length, and correlation between number of rows and ear diameter by 48%. The path diagram indicates that fresh weight, a crucial measure of crop yield, is strongly influenced by several agronomic traits, including plant height, ear length, ear diameter, dry weight, number of plants, row length, brix, and ear stalk. G24 can indeed be used as one of the parents with other group in hybrid breeding programs.

Abstract

Cassava (Manihot esculenta) cultivation is often carried out with an intercropping pattern with upland rice (Oryza sativa L.) as an intercrop which is expected to increase production and maximize land use. Cassava and upland rice have the same land characteristics, which are planted on dry land so they are suitable for intercropping. The effort used to make land efficient in this system is to adjust the planting time between intercropping plants and the main crop. The purpose of this study was to determine the effect of planting time of upland rice (Oryza sativa L.) on cassava (Manihot esculenta) intercropping. This research was carried out from May to September 2021 in front of Universitas Brawijaya at Mrican Village, Mojoroto District, Kediri City with a place height of 67-100 meters. The study was conducted using a one factor Randomized Block Design (RBD), which is planting time with a combination of 5 treatments and replications. The treatments used included W1: upland rice planting time 14 days before cassava, W2: upland rice planting time 7 days before cassava, W3: upland rice and cassava planted together, W4: upland rice planting time 7 days after cassava , W5 : planting time of upland rice 14 days after cassava. Data were analyzed using variance (ANOVA), if there was a significant effect it was continued with a follow-up test of Honest Significant Difference (BNJ) at 5% significance level. The most appropriate treatment is planting time for upland rice 14 days after cassava, due to the low competition between cassava and upland rice so that cassava and upland rice yields will remain good.
