Banana is one of the tropical fruits that people like because it tastes good and contains good nutritional value that beneficial for health.Ã‚Â The content of vitamin C and total sugar are an important character to complete the morphological characterization of banana accession that can be utilized by breeders in choosing accession as parent. The study aimed to determine the content of vitamin C and total sugar on 31 accessions of banana collection of Banana Germplasm Plants of Yogyakarta. The research was conducted at Banana Germplasm Plantation and Laboratory of Agricultural Technology Production of Gadjah Mada University, Yogyakarta from January to December 2016. The results indicated that 31 banana accessions showed their susceptibility to vitamin C content 60.42 + 39.22 mg / 100 g and total sugar 22.06 + 16.01%. High standard deviation values indicate the large diversity of banana accessions that were characterized, indicating that the accessions of each characterized banana were separate accessions of one another.

Penelitian bertujuan untuk mengetahui pengaruh pola tanam monokultur dan tumpangsari terhadap hasil jagung dan tiga varietas padi di lahan kering. Penelitian ini dilaksanakan di Trenggono Kidul, Gunungkidul, pada bulan Maret-Agustus 2020 dengan Rancangan Acak Kelompok Faktorial 3 ulangan. Perlakuan meliputi monokultur Nasa 29, monokultur Inpari 42, monokultur Inpari 43, monokultur Inpago 10, tumpang sari Nasa 29 dan Inpari 42, tumpang sari Nasa 29 dan Inpari 43, dan tumpang sari Nasa 29 dan Inpago 10. Variabel tanaman jagung meliputi: tinggi tanaman, bobot brangkasan basah, bobot brangkasan kering, bobot jagung dengan kelobot, panjang tongkol jagung, bobot jagung pipilan, bobot tongkol tanpa biji dan bobot 100 biji. Variabel pengamatan tanaman padi meliputi tinggi tanaman, jumlah anakan, panjang daun, lebar daun, panjang malai, jumlah gabah isi per malai, bobot 100 butir gabah, dan bobot gabah per rumpun. Analysis of Variance (ANOVA) pada α= 5% digunakan dalam analisis data dan untuk mengetahui perbedaan di antara perlakuan menggunakan uji DMRT pada α= 5%. Hasil penelitian menunjukan jagung Nasa 29 secara tumpang sari dengan ketiga varietas padi (Inpari 42, Inpari 43 dan Inpago 10) tidak berbeda nyata dengan hasil jagung Nasa 29 secara monokultur. Hasil monokultur padi (Inpari 42, Inpari 43, dan Inpago 10) dibanding dengan hasil padi secara tumpang sari dengan jagung Nasa 29 menunjukkan beda nyata, dimana hasil monokultur lebih unggul daripada tumpang sari. Paket tumpang sari yang dapat memberikan hasil jagung maupun padi yang terbaik diperoleh pada tumpang sari jagung Nasa 29-Inpari 43 dengan nisbah kesetaraan lahan (NKL) 1,24 artinya penerapan pola tanam tumpang sari masih tergolong menguntungkan karena memiliki nisbah kesetaraan lahan (NKL) lebih besar dari satu.

Rice is one of the essential daily commodity for most of Asian. However, the brown plant hopper (BPH; Nilaparvata lugens) infestation had been threatening the increasing demand of rice production. Evaluating resistance level of rice cultivars against BPH will help in managing BPH infestation. The feeding behavior monitoring of brown plant hopper (BPH; Nilaparvata lugens) by using an electrical penetration graph (EPG) was conducted to evaluate the resistance level of several rice cultivars against BPH, including pigmented rice (black rice cv. Sembada hitam; red rice cv. Sembada merah); and the commonly consumed white rice (cv. Ciherang). The EPG instrument allowed the monitoring of BPH feeding behaviors by quantifying three unique waveforms, namely, N3, N4, and N5, which represent BPH feeding activities in areas near phloem tissues, in phloem tissues, and in xylem tissues, respectively. EPG monitoring of BPH feeding activities in black rice revealed the absence of the N3 and N4 waveforms. Red rice showed the N3 waveform but not the N4 waveform. White rice showed all three waveforms occurring with high numbers and long total durations. The absence of the N4 waveform in the two pigmented rice cultivars indicated the failure of BPH to access phloem tissues. Overall, the results revealed that the resistance of rice against BPH based on feeding activity could be ordered as follows: black rice > red rice > white rice. This report provides essential information on the resistance mechanism of pigmented rice cultivars against BPH.

ARTICLE HIGLIGHTS- Sorghum nutrition varies across varieties and growing seasons- Dry season increases starch and amylose content in some varieties- Rainy season enhances protein levels in sorghum grains- Genotype-environment interaction affects sorghum nutritional quality- Sorghum adaptation supports food diversification and climate resilienceABSTRACTSorghum (Sorghum bicolor (L.) Moench) is a potential staple food in Indonesia, offering an alternative to rice and corn due to its adaptability to marginal lands and drought tolerance. However, research on the impact of environmental factors, particularly different growing seasons, to the nutritional composition of sorghum varieties are still lacking. This study aimed to analyze the proximate contents of tannin and amylose in six sorghum varieties cultivated in two different planting seasons (wet and dry seasons). A Completely Randomized Design with three replications was applied in this experiment. The tested varieties included three newly developed superior varieties (Bioguma, Samurai, and Kawali) and three local varieties (Black Bonteb, Red Glutinous Sorghum, and KD4). The results showed that proximate composition varied across varieties and seasons. Starch content was generally higher in the dry season, with the highest observed in Kawali (64.16%) and Bioguma (63.11%), while the lowest was in Black Wareng (11.99%). Similarly, protein content peaked in Black Wareng (7.68%) and Red Glutinous Sorghum (7.37%), but was the lowest in Samurai (4.48%). Tannin levels also fluctuated by season, where Bioguma, KD4, and Kawali exhibited higher tannin content in the dry season, whereas Samurai, Red Glutinous Sorghum, and Black Bonteb had lower tannin levels. Notably, amylose content was significantly higher in Red Glutinous Sorghum (4.72%) and Black Bonteb (4.62%) across both seasons, contributing to their fluffier texture when cooked. These findings highlight the influence of environmental conditions on sorghum nutritional quality, reinforcing its potential for food diversification, including processed sorghum flour as a substitute for wheat flour.

The local Segreng red rice has been recognized in Gunung Kidul since the 1940s. Testing was done by tracing Segreng's existence, then selecting, characterizing, and introducing its description during 2005-2007. Testing was done in six villages: (1) Ngeposari, in Semanu Sub-District, (2) Pacareja, in Semanu Sub District, (3) Genjahan in Ponjong Sub-District, (4) Genjahan in Ponjong Sub-District, (5) Sumberwungu, in Tepus Sub-District, and (6) Mulo in Wonosari Sub-District. Qualitative character observation was done on location based on rice plant characterization, vegetative characteristics (height, leaf length, flag leaf width) and generative characteristics (number of cluster number of solid grain, number of hollow grain) and laboratory testing. Research resulted that segreng differed to Aek Sibundong and was a sole variety as to be listed in the genetic resource collection.
