Cruciferous vegetables are very important agricultural commodities for increasing farmers income. The main obstacles in their cultivation involved among others high level of pathogen infestation that may cause reduction in farmer’s income. This research was conducted to determine the main pathogens and their impact on farmer income in Agropolitan area of Cianjur Regency, West Java Province. The research was conducted through three activities, i.e. farmer survey, identification of the main pathogens, and measurement of disease intensity. The results showed that there were three main pathogens on assessed cruciferous vegetables, i.e. Alternaria brassiccicola (alternaria leaf spot), Plasmodiophora brassicae (clubroot), and Xanthomonas campestris (black rot), with disease intensity of 16.7%, 18.7%, and 15.1%, respectively. Clubroot disease was the most affecting disease in decreasing the production of cruciferous vegetables and the farmer income. Incidence of clubroot disease with an average disease intensity of 16.67% might lead to the decrease of farming income about 24%–28%.
Terbatasnya varietas padi tahan kering merupakan salah satu masalah dalam budadaya padi di lahan kering. Genotype mutan tahan kering dari hasil iradiasi sinar gamma sebagai padi gogo penampilannya dapat diuji pada lahan sawah tanpa genangan. Penelitian ini bertujuan untuk menilai penampilan agronomi beberapa genotype mutan sebagai padi gogo di lahan sawah pada musim tanam kering. Penelitian dilasaksanakan di Kelurahan Turikale, Kecamatan Turikale, Kabupaten Maros, Sulawesi Selatan, berlangsung dari bulan Juli - Agustus 2019. Material percobaan adalah benih mutan padi gogo hasil iradiasi sinar gamma bersumber dari BB-Biogen Bogor sebanyak 8 nomor, menggunakan Rancangan Acak Kelompok dengan tiga ulangan. Hasil penelitian menunjukkan bahwa terdapat perbedaan penampilan beberapa karakter antar genotipe mutan padi gogo dengan varietas IR-64 dan Situ Bagendit sebagai pembanding. Genotipe dengan jumlah bulir per malai lebih banyak yaitu GT63-E25 (199,57 bulir), GT63-E11 (186,40 bulir) dan GT 73-E45 (189,43 bulir). Bobot 1000 biji lebih berat yaitu GT73-E45 (26,34 g), GT63-E07 (27,99 g) dan GT63-E25 (27,15 g). Genotype yang mempunyai bobot gabah KA 14 % GT73-E45 (8,99 t ha-1), GT63-E25 (8,53 t ha-1), dan GT63-E11 (8,24 t ha-1), sedangkan varietas IR 64 (6,60 t ha-1) dan Situ Bagendit (6,71 t ha-1).
