Abstract

Uwi (Dioscorea alata) merupakan tanaman pangan lokal yang prospektif dan dapat digunakan sebagai pangan fungsional dan bahan diversifikasi pangan. Uwi mengandung karbohidrat dan protein tinggi namun rendah kadar gula. Berbagai penelitian telah mengungkapkan manfaat uwi bagi kesehatan, seperti dapat digunakan sebagai pengganti nasi untuk penderita diabetes, mengurangi risiko terkena kanker payudara dan penyakit kardiovaskular, serta dapat digunakan sebagai obat terapi pada penderita osteoporosis dan memelihara kesehatan usus. Budidaya tanaman uwi relatif mudah dan tidak memerlukan perawatan khusus, masa dormansi umbi yang panjang dapat dipersingkat hingga 1 bulan, satu umbi berukuran sedang dapat menghasilkan 16– 24 batang bibit. Untuk mempermudah proses pengolahan uwi, sebaiknya dilakukan perbaikan genetik ubi uwi yang memiliki bentuk seragam dan kandungan nutrisi yang baik. Prospek uwi sebagai pangan fungsional dan bahan diversifikasi pangan dapat dilakukan dengan proses pembuatan tepung yang memiliki kapasitas antioksidan yang baik selanjutnya dapat digunakan untuk pembuatan beragam produk olahan modern seperti roti, kue kering (cookies), flakes, muffin, mie atau bihun. Selain itu sosialisasi dan promosi mengenai keunggulan uwi dari segi kesehatan juga diperlukan untuk meningkatkan nilai ekonomi uwi.

Abstract

Sekitar 60% produksi kedelai nasional dihasilkan dari lahan sawah. Namun, budi daya kedelai di lahan sawah menghadapi berbagai masalah, antara lain cekaman genangan. Genangan menyebabkan penuaan dini sehingga daun klorosis, nekrosis, dan gugur serta pertumbuhan tanaman terhambat, yang pada akhirnya menurunkan hasil. Umumnya kehilangan hasil pada fase vegetatif lebih kecil dibandingkan pada fase reproduktif, yaitu 1743% pada fase vegetatif dan 5056% pada fase reproduktif. Besarnya penurunan hasil bergantung pada varietas kedelai yang ditanam, fase pertumbuhan tanaman, lamanya tergenang, tekstur tanah, dan kehadiran penyakit. Tersedianya varietas kedelai toleran genangan akan memberikan arti penting bagi upaya mempercepat peningkatan produksikedelai dalam negeri. Pengembangan kedelai toleran genangan tidak hanya bermanfaat dalam pengembangan kedelai di lahan sawah, tetapi juga wilayah yang sering mengalami cekaman genangan seperti lahan pasang surut. Luas lahan pasang surut di Indonesia mencapai 20,10 juta ha, sekitar 2030% di antaranya berpotensi sebagai lahan pertanian. Program perakitan varietas kedelai toleran genangan berpeluang dilakukan jika tersedia sumber gen dan metode skrining yang sederhana, mudah, dan cepat. Karakter morfologi dan fisiologi yang dapat secara cepat mendeteksi indikator toleransi kedelai terhadap genangan adalah perkecambahan, tinggi tanaman, perubahan warna daun menjadi kuning, kehadiran akar adventif, bobot kering akar, penutupan stomata, dan kadar N total. Kerja sama dengan lembaga internasional terutama dalam pertukaran sumber gen akan mempercepat program pemuliaan kedelai toleran genangan.

Abstract

Salinity is a major abiotic stress limiting mungbean production worldwide including Indonesia. Since mungbean plant is very sensitive to salt condition, selection of salinity tolerant genotypes becomes important for mungbean improvement. The objective of this study was to evaluate the tolerance of eight mungbean genotypes to salinity at seedling stage under different levels. The experiment was arranged in a randomized complete block design with two factors (mungbean genotypes and salinity levels) and triplicates. Observation variables were germination percentage, vigor index, germination rate, hypocotyls length, epicotyls length, root length, number of root, seedling fresh weight, and seedling dry weight. The result showed that increasing level of salinity concentration inhibited the speed of germination, germination percentage, vigor index, normal seedling fresh weight, and number of lateral roots. Murai and Vima 1 were identified as tolerant genotypes, while Vima-2 and MLGV 0180 were identified as salinity sensitive genotypes at seedling stage. Currently, mungbean varieties with special characters, such as saline-tolerant is not yet available. The availability of saline-tolerant variety of mungbean is a cheaper and easier technology for farmers to anticipate the expansion of the saline area. The tolerant genotypes may be further tested at the later stage to obtain promising genotype tolerant to salinity that effectively assist mungbean breeding program.

Abstract

In Indonesia, cowpea (Vigna unguiculata L. Walp) is widely cultivated in the dry climate area. Famers used the seeds from previous plants or traditional markets. The aims of the study were to determine the effect of seed position in the pods on seed viability and to study the seed and seedling characteristics regarding the genetic variation and seed position. The cowpea used in this study was from 18 Indonesian local varieties. Twenty-five matured pods were randomly detached from each variety. Each pod was divided into three parts, i.e. the lower third (base), the middle third, and the upper third (tip). The seeds of each part were germinated using sand media to evaluate their viability. Each local variety has different response to the percentage of seed viability in each seed position in the pod. The highest abnormal germination occurred in the seed from lower part of the pod, followed by seed in the middle of the pod and the tip of the pod. The variation of seed viability in pods was more determined by genetic differences in local varieties. The average seed viability from three parts of the pods was highest for seeds originated from local varieties of Lumajang and Sampang. Therefore, it is recommended that the seeds of both local varieties can be mixed to be used for optimum cowpea cultivation.

Abstract

Soil-borne disease caused by fungus infection is one of the disease that causes the death and crop failure of mungbean. The aim of this study was to identify the performance, yield component and respons of plant to the disease. Performance of 25 genotypes were observed in installations research and assessment of agriculture technology (IPPTP), Jambegede of Indonesian Legumes and Tuber Crops Research Institute (ILETRI)at dry season 2018 using RCBD with three replications. The result showed that each variety has different characteristic. The plant with the highest number of plant height was genotype 15 and 18, while the total branches of 25 genotypes were generally similar (4).The highest number of grown and harvested plant was genotype 15. The genotypes with shorter flowering, maturity and harvesting age were 23, 20, 18, 15 and 10. The highest average number of filled pods was genotype 11 and empty pods was genotype 13. There were 8,10 and 2 genotypes with seeds weight of >7, >6 and <6 respectively. The highest yields were obtained from genotype 19 and 3 by total of yield of 2.0 t/ha and 1,9 ton/ha respectively. Resistance test against soil-borne diseases resulted 5 genotypes that were moderate resistant observed at 2 DAP. This research contributed to gave information about new genotypes of mungbean that potentially produce new superior varieties.
