Sweet corn is a horticultural crop that is widely cultivated and consumed by Indonesian people. Meeting the demand for sweet corn is still reliant on imports; therefore, increasing production by improving soil properties through proper fertilization. Cow manure with a content of N 2.33%, P 0.61%, and K 1.58% is able to add nutrients to the soil. This research aimed to obtain an optimum dose of organic fertilizer for sweet corn growth and yield. The doses of cow manure consisting of 5 levels: control, 10, 20, 30, and 40 tons ha⁻¹ were assigned in the randomized complete block design with 5 replications. Data analysis deployed analysis of variance (Anova) at 5% level, and if there were significant differences, it would be proceeded to Duncan Multiple Range Test 5% and orthogonal polynomial. The results showed that a dose of 20 tons ha⁻¹ was able to increase growth in plant height, stem diameter and number of leaves by 12.92%, 26.29%, and 15.67%, respectively, compared to the control. A dose of 35 tons ha⁻¹ can produce a weight of cob-husk and cob without-husk per plot, respectively, 4.38 kg plot⁻¹ and 2.64 kg plot⁻¹, and a productivity of cob-husk of 5.30 tons ha⁻¹. A dose of 38 tons ha⁻¹ can produce a cob without-husk productivity of 3.29 tons ha⁻¹.

Dendrobium are one of the most cultivated ornamental orchids plants. However, orchids as genetic resources have not been optimally utilized as parents in crossing to produce offspring according to the characteristics desired by consumers. This study aims to study the similarities between the Hybrid results of crosses compared to their parent orchids and obtain a new variety of Hybrid from crosses of Dendrobium bigibbum and Dendrobium lineale. This research was conducted at the Bogor Botanical Gardens and Plosorejo Village, Matesih District, Karanganyar Regency, Central Java. The materials used were 14 samples of orchid plants, including three examples of D. bigibbum orchids, three samples of D. lineale orchids, four samples of Hybrid plants resulting from crosses of ♀ D. bigibbum X ♂ D. lineale, and four samples of Hybrid plants from crossing ♀ D. lineale X ♂ D. bigibbum. Observation variables include quantitative variables. The quantitative morphological variables use the guideline developed by BALITHI. To analyze the data using the program of NTSYSpc 2.02i version. The results showed that based on quantitative observations, Dendrobium lineale as a female parent can change the size of the dorsal sepal width, flower arrangement length, lateral sepal length, and flower length. And Dendrobium bigibbum as the female parent can change the size of the petal length, lateral sepal width, flower width, pseudobulb thickness, pseudobulb length, leaf length, and leaf width.

Black rice generally has problems in cultivation such as relatively long plant life, high habitus and low productivity. Plant breeders use several methods in hybridization activities, such as backcross method that can lead to the development towards emphasizing the superiority of each parent. This research aimed to study and determined the success rate of the black rice lines F1 backcross and the parents’ performance. This research was conducted using F1 of promising lines, parental lines and the Jeliteng variety with 9 sets of crosses. Each line and variety were repeated 3 times, in total there were 57 experimental units. The observation parameters of this research were plant height, crossing success, weight of seeds, length and width of grain, flowering age, harvesting age also number of grains and unfilled spikelet. The results of this study showed that parents plant height was positively correlated with the number of productive tillers. The taller the plant, the more productive tillers and the more flowers can be crossed. The success of the cross can increase with the number of flowers crossed. The success of crosses between F1 black rice promising lines and their parents has a success rate range of 10.82% to 33.75%. The findings imply that F1 crossbreeding of black rice promising lines with their parents can be carried out to produce backcross offspring.

Desa Wisata Samiran berada di Kecamatan Selo Kabupaten Boyolali, mempunyai luas 663,329 ha dengan elevasi 1.400-2.550 m dpl, serta jenis tanah Andosol (lereng Merbabu) dan Regosol (lereng Merapi). Secara agroklimat cocok untuk pengembangan agrowisata tanaman perkebunan (teh dan kopi Arabika), tanaman buah (tledung, apel, dan jeruk), tanaman hias, serta sayuran. Kegiatan PKM (Program Kemitraan Masyarakat) ini bertujuan untuk introduksi tanaman Teh (Camellia Sinensis L.O. Kuntze) dan tanaman Apel India (Ziziphus Muritania) pada kelompok tani di Desa Wisata Samiran. Tanaman Teh Varietas Gambung-7 diintroduksikan sebagai tanaman pagar (hedgerows) dikiri-kanan lorong jalan desa, sedangkan tanaman Apel India sebagai tanaman buah di pekarangan petani. Mitra yang dipilih yaitu Kelompok Tani Taruna Subur (Dukuh Samiran, Desa Samiran, Kec. Selo) dan Agrowisata Tretes Taman Tani (Dukuh Tretes, Desa Samiran, Kec. Selo). Metode yang digunakan meliputi : (a) penyuluhan dan sosialisasi program PKM; (b) pemberian bibit dan penanaman Teh sebagai tanaman pagar di lorong kiri-kanan jalan desa; (c) pemberian bibit dan penanaman Apel India sebagai tanaman buah di pekarangan rumah; serta (d) pemberian bibit Teh dan Apel India di Agrowisata Tretes Taman Tani. Seluruh anggota kelompok tani dilibatkan dari kegiatan penyuluhan, pemberian bibit, penyiapan lahan dan penanaman, serta perawatan tanaman. Target dari PKM ini untuk meningkatkan atensi akademisi Riset Grup Pengelolaan DAS dan Agroekosistem Fakultas Pertanian UNS, bersama kelompok tani untuk ikut berpartisipasi di dalam pengembangan Desa Wisata Samiran yang lebih asri dan sejahtera.
