Asian vegetable crops are rapidly expanding in Florida in the last decade due to their health benefits combined with their high profitability. These crops can help increase vegetable growers’ income and diversify Florida’s crop production, and they are new to most Floridians. This new 5-page article provides a general overview of bok choy for vegetable growers, crop consultants, certified crop advisors, Extension agents, and graduate students.

Penelitian ini bertujuan untuk mempelajari variabilitas genetik, heritabilitas, dan menyeleksi penampilan genotipe karakter agronomi unggul pada 57 galur sawi untuk digunakan dalam bahan baku konsumsi dan industri. Penelitian ini dilaksanakan di Seed Bank and Nursery, Agrotechno Park Universitas Brawijaya, Desa Jatikerto, Kecamatan Kromengan, Kabupaten Malang pada bulan Desember 2018 – April 2019. Metode yang digunakan untuk penelitian ini adalah rancangan acak kelompok diperluas (augmented design). Perlakuan yang diberikan adalah 60 genotipe sawi yang terdiri dari 57 genotipe yang diuji dan 3 varietas sebagai cek. Genotipe yang diuji akan disebar kedalam 5 blok, sedangkan tiga varietas cek akan ditanam pada setiap blok, sehingga terdapat 72 satuan percobaan. Variabel pengamatan karakter agronomi terdiri dari 15 karakter kualitatif dan 24 karakter kuantitatif. Variabilitas yang luas terdapat pada karakter biji per polong, jumlah polong per tanaman, dan berat segar. Heritabilitas tinggi terdapat pada karakter panjang kotiledon, jumlah daun konsumsi, berat segar, umur panen benih, jumlah polong per tanaman, panjang polong, lebar polong, dan jumlah biji per polong. Terdapat galur-galur sawi yang mempunyai karakter unggul untuk bahan baku konsumsi dan industri.

Indian mustard (Brassica juncea L. Czern) cultivation is suggested for regions with short seasons and low rainfall. Although there have been many studies conducted on agronomic production of mustard in Iran, the information regarding the interactive impact of cropping seasons and nitrogen fertiliser on growth characteristics and yield quality of mustard plant is still insufficient and requires further investigation. This study focused on the possible implications of different cropping seasons and different nitrogen levels on selected agronomic traits in mustard. In this experiment, five different doses of nitrogen and two sowing periods were used to assess for their combined effects on the growth parameters, seed yield and agronomic characteristics of mustard in the semi-arid climatic conditions of Takestan. The results revealed that cultivation seasons and nitrogen rates had a significant effect on plant height, biomass yield, number of siliques per plant, seed oil content and seed yield.

<p>Vietnam is a country that is suffered from frequent natural disasters. The most common types of natural disasters experienced are typhoon and flood. From 1951 to 2010, there were 166 typhoons come to Vietnam, of which 67 % hit the central region, 25 % to the north and 8 % to the south of the country. Typhoons bring heavy rains and high tides which accelerate floods, particularly in the coastal and lagoon areas of Central Vietnam. Identification of vulnerability to flooding and coping behavior of local people is required in the efforts to strengthen local capacity related to livelihood security in the study area. This study aims at characterizing the vulnerability of housing condition to flooding and the coping behaviors of local people after experienced big floods in Tam Giang lagoon area, Central Vietnam. Measurement of house’s foundation, observation of types of housing, interview to collect information about the water level during the events of big floods, year of construction and change of people’s behavior after the 1999’s flood were conducted with 427 households in Van Quat Dong village where four big flooding occurred in 1983, 1999, 2007 and 2009 during the last 30 years. The study shows that the 1999’s flood was the biggest flood with water height reached to 148.7 ± 23.9 cmfrom house floor and 222.6 ± 15.4 cmfrom ground level. The households located in the eastern part of the village are recognized more vulnerable to flood due to the lower altitude. The temporary and semi-permanent houses, which share 77.0 % to the entire houses, are considered to be relatively vulnerable to flooding due to weak housing materials and low height of foundation. The houses which categorized to permanent and semi-permanent types constructed after the 1999’s flood have higher foundation than the other houses constructed before the 1999’s flood. The raising of foundation height of permanent and semi-permanent houses, as well as an increase in numbers of two-storey houses, are recognized to be a behavior of local people to cope with flooding. The study also shows the relationship between the poverty level and the coping behaviors of households. Some of poor households in the village are still not in good preparedness to flooding. It suggests that poverty level of household concerns to the vulnerability to flooding and, therefore, rural development assistance to improve household economy for poverty alleviation is required in the efforts to strengthen local capacity related to livelihood security.<strong></strong></p>
