Plant spacing arrangement might benefit hill strength from the impact of strong wind velocity during extreme weather situations. Here, a loading test to evaluate rice hill strength was performed on Ciherang variety grown in square and double row spacing 2:1. The research was conducted at Cilubang village, Dramaga, Bogor, West Java, Indonesia from March to May 2017. Weight holding capacity was evaluated in 85 days after transplanting on four levels of hill height, i.e., 80 cm, 60 cm, 40 cm, and 20 cm above soil level with three-time replication. The results showed that double-spaced hills had 66.0 % ± 3.1 % stronger than those of square spacing at all height measurement. To lodge a hill into 20 cm to 40 cm from soil level, it required 346.7 g to 741.7 g in square spacing, and 555.2 g to 1149.2 g in double row spacing. Stronger hills in double row spacing seemed to correlate with a higher number of tiller and hills architecture; it requires further study in the role of both factors on the hill strength improvement. The present study recommends applying double row spacing to improve rice hill strength especially at a time with a high chance of lodging by strong wind incident.
在极端天气情况下，植物间距的安排可能会受益于强风速的影响。以慈和让品种为试验材料，以2:1的双行间距和方行间距种植，进行了水稻山强评价的加载试验。该研究于2017年3月至5月在印度尼西亚西爪哇茂物Dramaga的Cilubang村进行。在离土80 cm、60 cm、40 cm和20 cm 4个坡地高度上进行定植后85 d的保重能力评价，重复3次。结果表明，在所有高度测量中，双间距丘陵比方间距丘陵强66.0%±3.1%。要使一座小山离地20厘米至40厘米，在正方形间距上需要346.7至741.7克，在双行间距上需要555.2至1149.2克。双行间距的强丘似乎与较高的分蘖数和丘结构相关;这两种因素在提高坡道强度中的作用有待进一步研究。本研究建议采用双行间距来提高水稻的山强，特别是在强风事件极易倒伏的时候。

Moringa plants grow in Sumenep with semi-intensive planting at the moor and several planting sites. Sumenep is one of the districts in Madura Island, which is categorized as a dry area based on the Oldeman climate classification. Based on the color of the leaf stalk, moringa plants growing in Sumenep area are categorized as green and purple moringa. The study aimed to examine the differences in physiological characteristics of two accession of moringa plants at different planting sites in Madura. The study was arranged in Oversite Sub-sampling Design with planting site as first factor consisting of Bluto with E5 climate type and Guluk-guluk with D3 climate type. Meanwhile, the second factor was the type of moringa consisting of moringa with green and purple leaf stalks. The results showed that the different planting sites represented the differences in environmental elements, which influenced the physiological characteristics of moringa plants. Based on the observation in September 2016, moringa plants with green stalks planted in Guluk-guluk had high ANR content. The stomatal opening on moringa leaves with green stalks was larger than that on moringa plants with purple stalks, whereas ANR content in green-stalked moringa was lower than in the purple-stalked ones. Meanwhile, in February 2017, the purple-stalked moringa plants planted at Bluto had the highest transpiration rate and proline content compared to the others.
