In the present study, we examined the relationship between UAV-NDVI and NDVI measured with the GreenSeeker handheld crop sensor (GS-NDVI), and between grain yield and UAV-NDVI or GS-NDVI at the reproductive stage in the plant communities at 4–1 week (wk) before heading in 2018 and 2019 and in 2020 and 2021, respectively. In the data of each measurement day in 2018 and 2019, the relationship between UAV-NDVI and GS-NDVI was strongly positive. However, in the pooled data of different measurement days, the relationship between UAV-NDVI and GS-NDVI was weakly positive. This was because GS-NDVI was more constant under various climatic conditions and across various time of day than UAV-NDVI at the reproductive stage. Furthermore, in the pooled data of different years in 2020 and 2021, GS-NDVI correlated more strongly with grain yield than UAV-NDVI between 3 and 1 wk before heading. To increase the efficiency of growth diagnosis and yield prediction in the numerous farmers’ fields, UAV-NDVI could be used with correction by a few measurements of GS-NDVI determined on the same day.</div>","PeriodicalId":100340,"journal":{"name":"Crop and Environment","volume":"2 2","pages":"Pages 59-65"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49708269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Replacing summer fallow with a legume grown as a green manure would help reduce soil erosion, improve precipitation use efficiency, and add nitrogen (N) credits for the subsequent wheat crop. A two-year field experiment evaluated the capabilities of three summer pulses: soybean [Glycine max (L.) Merr.], moth bean [Vigna aconitifolia (Jacq.) Marechal], and tepary bean [Phaseolus acutifolius (A.) Gray] to serve as green manures and soil cover. We examined their performance across two row spacings (38 and 76 cm) and two moisture regimes (rainfed and irrigated). Narrow row spacing (38 cm) provided greater canopy cover, aboveground biomass, and N accumulation than the broad row spacing (76 cm) during the early growing season. Among species, tepary bean demonstrated consistent and higher canopy cover early in the season. Soybean produced the highest aboveground biomass (5,327–8,855 kg ha−1) and N accumulation (115–269 kg ha−1) among the three pulses. Multilinear regression (MLR) models suggested that canopy height and canopy cover could estimate both aboveground biomass (R2 = 0.62) and N accumulation (R2 = 0.55) for tested pulses. Based on results, soybean was the most promising choice among tested pulses, considering its higher aboveground biomass and N accumulation.

Experiments were conducted in a high-yielding environment with total N applied up to 180 kg ha−1 and three application times to determine its effect on N uptake, grain yield and grain protein content of rice grown under aerobic (AR), delayed permanent water (DPW) and flooded (FD) conditions. Grain yield increased by 3.50–4.50 t ha−1 with total N application rate of 180 kg ha−1 in AR and 120 kg ha−1 in both DPW and FD. Maximum yield was about 10.5, 12.0 and 13.0 t ha−1 in AR, DPW and FD, respectively, and the difference was mostly reflected in the grain yield difference obtained under 0 N application. Apparent recovery of fertilised N and agronomic N use efficiency were similar between AR and FD, but DPW took up a higher proportion of N fertiliser applied before commencement of flooding and had slightly higher grain yield response to total N application up to 120 kg ha−1. It is concluded that the limitation for grain yield for rice grown in the AR condition was the crop's inability to take up N from the soil, rather than the inability to take up N fertiliser or to convert the N uptake to grain yield.</div>","PeriodicalId":100340,"journal":{"name":"Crop and Environment","volume":"2 1","pages":"Pages 37-45"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49732252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key practices for achieving high yield in mechanized rice ratooning system are variety selection, optimization of planting date, proper water and fertilizer management, and optimal straw cutting height. With implementation of those key practices, the grain yield of ratoon rice has increased significantly, especially in the ratoon season.

Optimization of antenna size of photosynthetic systems is one strategy to increase plant photosynthetic efficiency. However, applying this strategy to improve photosynthesis received conflicting results, and the reasons behind these conflicts are unclear. In this study, we constructed transgenic rice with amiRNA targeting to YGL1, which encodes a key enzyme of chlorophyll a/b synthesis in chlorophyll biosynthesis pathway, to generate different lines with different leaf chlorophyll contents and antenna sizes to test under what conditions reduction of antenna size can improve photosynthesis. We found that leaf photosynthesis, canopy photosynthesis (Ac), biomass and grain yield of the heterozygote were not significantly different from those of wild type (WT) while the Ac, biomass and yield of the homozygote were lower than those of WT. Further, when the maximal quantum yield of photosystem II (Fv/Fm) was larger than 0.8, decreasing antenna size by reducing chlorophyll biosynthesis didn't affect leaf photosynthesis. In view of this phenomenon, we proposed that the accumulation of protoporphyrin and the reduced photoprotection capacity might be the cause of the decrease in Fv/Fm and Ac. Therefore, this study shows that reduction of antenna size by inhibiting chlorophyll synthesis can lead to improved light distribution and photosystem efficiency, as long as photodamage and photobleaching can be avoided to maintain the photosystem II efficiency. The double-edged sword effect of inhibiting chlorophyll synthesis on photosynthetic efficiency should be considered when the antenna size is manipulated to gain higher photosynthesis.</div>","PeriodicalId":100340,"journal":{"name":"Crop and Environment","volume":"2 1","pages":"Pages 46-58"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49708410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
