Although studies on the balance between yield and quality of japonica soft super rice are limited, they crucial for cultivation. In order to investigate effects nitrogen application rate grain quality, two varieties, Nanjing 9108 (NJ 9108) 5055 5055), were used under seven N levels with rates 0, 150, 187.5, 225, 262.5, 300, 337.5 kg ha−1. With increasing level, both varieties first increased then decreased. The highest was obtained at 300 milling protein content increased, while appearance...
Abstract Normalized difference vegetation index (NDVI) is one of the most important indices in crop remote sensing. It features a simple, fast, and non-destructive method has been widely used monitoring growing status. Beer-Lambert law calculating leaf area (LAI), however, it time-consuming detection low output. Our objective was to improve accuracy LAI through sensing by integrating NDVI law. In this study, firstly modified construct model with as independent variable. Secondly,...
Nitrogen fertilizer is an important agronomic measure to regulate rice yield and grain quality. Grain filling crucial for the formation of However, there are few studies on effects excessive nitrogen application (ENA) rate A two-year field experiment was conducted reveal difference in characteristics quality superior grains (SG) inferior (IG), as well their responses fertilizer. We determined appearance, yield, SG IG, found that with increasing level, both varieties first increased then...
Nitrogen management (nitrogen application ratio at transplanting, tillering, and panicle initiation growth stages) is an important parameter in crop cultivation closely associated with rice yield grain quality. The physicochemical structural properties of starches separated from two varieties grown under three different nitrogen ratios (9:1; 7:3; 6:4) were investigated. As the percentage used stage increased, content small starch granules improved, whereas large decreased. Amylose decreased...
Side deep placement of nitrogen plays an important role in improving rice yield and use efficiency. Few studies have examined the effects reducing times (RTN) application rate (RNR) on efficiency under side paddy fields. Therefore, a field experiment RNT RNR treatments was conducted with nine fertilization modes during 2018–2019 growing seasons rice–wheat cropping system lower reaches Yangtze River, China. Rice were investigated nitrogen. We found that same rate, RTN3 increased by 9.64...
In recent years, the delay in sowing has become a major obstacle to high wheat yield Jiangsu Province, one of producing areas China; hence, it is necessary screen varieties are resilient for late sowing. This study aimed provide an effective, fast, and non-destructive monitoring method soil plant analysis development (SPAD) values, which can represent leaf chlorophyll contents, late-sown winter variety screening. acquired multispectral images using unmanned aerial vehicle (UAV) at...
Numerous papers studied the relations between nitrogen rate and rice yield in saline soils, whereas root morphological physiological characteristics mediating rates formation under varied salinity levels remain less concerns. Through a field experiment applied with five (0, 210, 255, 300, 345, 390 kg ha –1 ) land, we found that peaked at 7.7 t 300 nitrogen, excessive N was not conductive for increasing yield. To further elucidate its internal mechanism, pot designed three (210 [N1], [N2],...
Leaf area index (LAI) is one of the indicators measuring growth rice in field. LAI monitoring plays an important role ensuring stable increase grain yield. In this study, canopy reflectance spectrum was obtained by ASD at elongation, booting, heading and post-flowering stages rice, correlations between original (OR), first-derivative transformation (FD), reciprocal (1/R), logarithmic (LOG) with were analyzed. Characteristic bands spectral data then selected based on successive projections...
Controlled-release urea (CRU) is widely adopted to improve yields and nitrogen use efficiencies (NUEs) in rice. However, there are few studies on the effects of mixed application CRU normal (at different N ratios) rice yield, efficiency, grain quality. A series simplified fertilization modes (SFMs) were set up 2018–2019. with release periods 80 days 120 at ratios 7:3, 6:4, 5:5, 4:6, 3:7 applied during rice-growing season. We determined dry matter accumulation, NUEs, The SFM_80_6/4 (CRU 6:4)...
Several studies have demonstrated the effect of planting methods on rice yield, but information climate resources is limited. This study aims to reveal effects associated with yield in a rice-wheat rotation system lower reaches Yangtze River, China. Field experiments were conducted 2014 and 2015 two japonica, indica hybrid, japonica-indica hybrid varieties grown under three mechanized methods: carpet seedling mechanical transplanting (CT), direct seeding (DS), pot-hole (PT). The total dry...
Understanding the differences in yield traits of rice among pothole seedling mechanical transplanting (PSMT), carpet (CSMT) and direct seeding (MDS) is great importance not only for scientists but also farmers to develop a high-yield production system under conditions rice-wheat rotation system. However, such are yet be studied varieties japonica-indica hybrid (JIHR), japonica conventional (JCR) indica (IHR). Field experiments were conducted 2014 2015, where six cultivars three types JIHR,...
Abstract Background and objectives Temperature during the grain filling stage is critical environmental factor affecting rice quality starch physicochemical properties. Two soft japonica varieties were used to investigate morphological structure, gelatinization, pasting properties, as well overall sensory of cooked under different ripening dynamic temperatures. Findings Compared normal temperature (NT), low (LT) increased amylose content significantly influenced crystalline structure starch....
Soil moisture plays an important role in rice (Oryza sativa L.) root development and grain quality. However, little is known about the effects of soil type on morphophysiological traits (RMTs) quality under different irrigation modes. A soil-grown experiment was conducted during 2016–2017 growing seasons Yangzhou city with three types, namely, clay soil, loamy sandy regimes, conventional (CI, 0 kPa), alternate wetting moderate drying (AWMD, −15 severe (AWSD, −25 kPa). The AWMD regime...
The simultaneous stresses of salinity and drought often co-occur during rice-growing periods in saline lands, due to inadequate water resources poor irrigation facilities. Hence, combined salinity-drought stress poses a major threat rice production. This study performed with two levels (NS, non-salinity; HS, high salinity) three treatments (CC, control condition; DJ, imposed at jointing; DH, heading) was conducted investigate the influences on leaf photosynthetic characteristics, biomass...
