“…S3 and S4), which implies that further increases in these parameters through plant breeding and crop management strategies could increase stem strength and lead to stronger stem lodging resistance. This is also in alignment with previous reports that stem diameter and flexural rigidity of basal internode could be used as an important criteria for future variety improvement with robust stem breaking resistance (Liu et al., ; Niu et al., ; Wu & Ma, ; Zhang et al., ).…”

Ridge-furrow with plastic film mulching (RFPFM) is widely used as a water-saving strategy for the improvement of crop yield. However, lodging susceptibility under RFPFM practices has not yet been determined. A 2-yr field study comprising of three cultivation strategies (rain-fed flat planting [FP], RFPFM, and well-water planting [WW]) and two N application rates (75 and 225 kg N ha -1 ) was conducted to assess the risk of lodging and the relationship between lodging resistance and grain yields of two wheat (Triticum aestivum L.) varieties (Xinong979 as lodging resistant and Xiaoyan22 as lodging susceptible). The results showed that higher N application increased lodging index under FP and RFPFM, and the lodging index was 33% lower under RFPFM than under WW. In both years, there was a positive relationship between grain yield and lodging susceptibility (R 2 = 0.62** and 0.57**) implying that promoting crop yield by using RFPFM strategy accelerates the risk of lodging. When compared with WW, RFPFM significantly reduced the lodging index, while sustaining a comparable grain yield. Overall, RFPFM could be highly recommended as a promising strategy for winter wheat producers in dry, semi-humid regions. The close relationships of breaking resistance and lodging index with both mass density and stem wall thickness of basal internode suggest that selection for increased stem strength trait could lead to improved lodging resistance and higher yields in future programs for winter wheat cultivar improvement.Abbreviations: BM, bending moment; DAS, days after sowing; FP, rain-fed flat planting; LAI, leaf area index RFPFM, ridge-furrow with plastic film mulching; WW, well-water planting.

“…Crop lodging affects the rice yield and quality, and it is not easy with mechanical harvesting. Studies show that the varieties which plants are shorter, stems are sturdier, and root systems proliferate sufficiently, will have strong lodging resistance [91][92][93] . Most Chinese varieties currently adapt to transplant, and now some varieties with relatively strong lodging resistance and relatively high yield are selected for direct seeding.…”

Mechanized rice direct seeding is a cost-effective and efficient approach for rice cultivation. Recently, the use of rice direct seeding has been increasing rapidly owing to rural labour shortages and continuous increases in agricultural production costs. This article reviews the research and application progress of mechanized rice direct seeding including direct seeding technologies, precision rice seeding, precision rice seed-metering devices, key supporting agronomy technologies for mechanized rice direct seeding. South China Agricultural University developed precision rice hill-drop drilling (PRHDD) with synchronous furrowing and ridging technology and series machines for paddy that affords remarkable advantages in terms of saving time and labour, higher yield, and higher efficiency. In this approach, pre-germinated seeds are uniformly hill-dropped in the expected positions in puddled soil. It significantly improved the crop growth population and effectively solved the problems of high frequency of disease and pests caused by the irregular distribution of rice seeds with manual broadcasting, and generally reduces seed usage and increases the yield. Therefore, this technology has broad application prospects and great potential for promoting the development of mechanized rice direct seeding in China.

“…Tanaman padi sangat rentan terhadap kerebahan akibat cuaca ekstrim (Las, 2008). Fenomena rebah telah lama dikaji (Islam et al, 2007;Salasi et al, 2013;Zhang et al, 2014a), namun data kuantitatif kerebahan akibat cuaca ekstrim masih terbatas. Kashiwagi et al (2006) dan Weerakoon et al (2008) menyatakan bahwa rebah akan mengganggu transport air, unsur hara, dan asimilat akibatnya tanaman mengalami kehilangan hasil.…”

“…Dalam mengantisipasi dampak cuaca ekstrim, banyak peneliti menggunakan pendekatan genetik pada aspek kekeringan (Tubur et al, 2012), genangan (Hairmansis et al, 2012), dan tahan rebah (Mactal et al, 2015;Ookawa et al, 2010;Zhang et al, 2014a). IRRI (1988) mengembangkan pendekatan skoring nilai indek kerebahan yakni: 0, 1, 3, 5, 7, dan 9; nilai 0 menunjukkan tanaman sangat tahan rebah sedangkan nilai 9 sangat peka.…”

AbstractRice lodging due to incident of extreme weather, i.e., combination of strong winds and high rainfall is eviden in Indonesia. However, yield loss in the area is rarely studied. In order to estimate yield loss on rice, a model for calculating the yield reduction was developed. The objective of present study was to analyze the effect of strong winds and high rainfall incidents on yield loss of rice in the field. The study was conducted at the Sawah Baru IPB, Bogor, Indonesia from February to April, 2016 on rice plots severe from natural incident of strong wind and high rainfall. The results showed that rice lodging from strong wind and high rainfall formed patterns and specific formations. We determined four major lodging formations, five lodging degrees, and eleven different patterns due to wind direction. Overall, lodging occured on research area of 27.6% with production loss up to 11.89%. This research showed that estimation of yield loss due to incident of extreme weather could be conducted in the level of field based on area of coverage and degree of lodging. Application of the model on wider area needs further evaluation. Keywords: Agronomic character, extreme weather adaptation, modelling, lodging, rice variety
