Analysing the effect of paddy rice variety on fluorescence characteristics for nitrogen application monitoring.

ABSTRACT: Paddy rice is one of the most important cereal crops worldwide, so it is very important to accurately monitor its growth status and photosynthetic efficiency. The nitrogen (N) level is a key factor closely related to crop growth. In this study, laser-induced fluorescence (LIF) technology combined with multi-variate analysis was applied to investigate the effect of paddy rice variety on N fertilizer level monitoring. Principal components analysis was conducted to extract the variables of the main fluorescence characteristics to identify N levels. Experimental results demonstrated that no nitrogen fertilizer can be completely identified for each paddy rice variety. In addition, other N levels can also be well classified based on the fluorescence characteristics. The relationship between the fluorescence ratio (F735/F685?:?F735, and F685 denote the fluorescence intensity at 735?nm, and 685?nm, respectively) and leaf N content of different paddy rice varieties is also discussed. Experimental results revealed that LIF technology is an effective method of monitoring the N fertilizer and leaf biochemical components of paddy rice.

Project description:Combined application of biochar and nitrogen (N) fertilizer could offer opportunities to increase rice yield and reduce methane emissions from paddy fields. However, this strategy may increase nitrous oxide (N2O) emissions, hence its interactive effects on GHG emissions, global warming potential (GWP) and GHG intensity (GHGI) remained poorly understood. We conducted a systematic review to i) evaluate the overall effects of combined application of biochar and N fertilizer rates on GHGs emissions, GWP, rice yield, and GHGI, ii) determine the quantities of biochar and N-fertilizer application that increase rice yield and reduce GHGs emissions and GHGI, and iii) examine the effects of biochar and different types of nitrogen fertilizers on rice yield, GHGs, GWP, and GHGI using data from 45 research articles and 183 paired observations. The extracted data were grouped based on biochar and N rates used by researchers as well as N fertiliser types. Accordingly, biochar rates were grouped into low (≤9 tons/ha), medium (>9 and ≤ 20 ton/ha) and high (>20 tons/ha), while N rates were grouped into three categories: low (≤140 kg N/ha), medium (>140 and ≤ 240 kg N/ha), and high (>240 kg N/ha). For fertiliser types, N rates were grouped as: low (≤150 kg N/ha), medium (>150 and ≤250 kg N/ha), and high (>250 kg N/ha) and N types into: urea, NPK, NPK plus urea (NPK_urea) and NPK plus (NH4)2SO4 (NPK_(NH4)2SO4). Results showed that biochar and N fertiliser significantly affected GHGs emissions, GWP, GHGI and rice yield. Compared to control (i.e., sole N application), co-application of high biochar and medium N rates significantly decreased CH4 emission (82 %) while low biochar with low N rates enhanced CH4 emission (114 %). In contrast, high biochar combined with low N decreased N2O emission by 91 % whereas medium biochar and high N rates resulted in 82 % increase in N2O emission relative to control. The highest GWP and GHGI were observed under co-application of medium biochar and low N rates. Highest rice yield was observed under low biochar rate and high N rate. Regardless of N fertiliser type and biochar rates, increasing N rates increased rice yield and N2O emissions. The highest GWP and GHGI were recorded under sole NPK application. Combination of low biochar and medium N produced low GHGs emissions, high grain yield, and the lowest GHGI, and could be recommended to smallholder farmers to increase rice yield and reduce greenhouse gas emissions from paddy rice field. Further studies should be conducted to evaluate the effects of biochar properties on soil characteristics and greenhouse gas emissions.

Project description:The age of rice seedling at transplanting and application of nitrogen fertilizer are important husbandry practices for improved rice growth. The data showed the effect of variety, seedling transplanting age and nitrogen fertilizer rates on the growth of rice. Agronomic field trial was conducted during 2015 and 2016 planting seasons at National Cereals Research Institute Farms of Edozhigi and Badeggi located in the Southern Guinea Savannah of Nigeria. To assessed the effect of variety, seedling transplanting age and nitrogen fertilizer rates on the growth of rice. Treatments were laid out as split-split plot arrangement fitted into Randomized Complete Block Design (RCBD) with three replications. The main plot consisted of two rice varieties (FARO 44 and FARO 52), four seedling transplanting ages (7, 14, 21 and 28 days after planting) and five inorganic N fertilizer rates (0, 60, 120, 180 and 240 kg N/ha) constituted the sub-plot and sub-sub plot respectively. Growth data viz plant height, number of tillers and leaf area index were measured at 30 and 45 days after transplanting (DAT) during the two planting seasons. Plant height was taken from five randomly selected and tagged plants from ground surface to the tip of the leaf or panicle of the main stem using measuring tape. The number of tillers per plant was counted from five randomly selected and tagged hills in each plot from two middle rows. .The leaf area (cm2) of the leaves was obtained from five randomly selected tagged plants by measuring the leaf length from the base to the tip with a ruler also the widest part of the leaf. The leaf area (LA) was estimated using the equation: LA = length × breath × 0.75 [1]. The leaf area value obtained was used to calculate the leaf area index (LAI), which describes the efficiency of the photosynthetic process on the photosynthetic surface and calculated as the total leaf area/ground area. Data collected were subjected to one way analysis of variance (ANOVA) using GenSTAT 11th edition and the difference between treatments mean tested using least significant difference (LSD) at 5% probability level. The data are of value to agronomists in search of reference. It has the potential to be used to predict seedling age of rice at transplanting and the appropriate nitrogen fertilizer rate for rice growth.

Project description:Rice (Oryza sativa L.) is an important crop in China. Although it is known that its yield is restricted by nitrogen (N) supply, the response of the root system to N supply specifically has not been systematically explored. This study aimed to investigate the effect of N uptake on grain yield to clarify the relationships between root morphophysiological traits and N uptake, and to understand relation between phytohormones and root morphophysiological traits. Two N-efficient absorption cultivars (NEAs) and two N-inefficient absorption cultivars (NIAs) were grown in the field, and three N conditions, deficient N (60 kg ha-1), intermediate N (180 kg ha-1), and sufficient N (240 kg ha-1), were applied during the growing season. The results showed higher dry matter and grain yield in NEAs than in NIAs, which was mainly attributed to increased N uptake in the mid- and late growth stages under all N conditions. And NEAs have different root regulation methods to obtain higher N accumulation and yield under different N supply conditions. Under lower N conditions, compared with NIAs, NEAs shown greater total root length, root oxidation activity, and root active absorbing surface area and smaller root diameter owing to higher indole-3-acetic acid and cytokinin content and lower 1-aminocyclopropane-1-carboxylic acid content in the early growth stages to respond to low N stress faster, laying a morphophysiological basis for its high N-uptake capacity in the mid- and late growth stages. Under higher N conditions, NEAs had higher root oxidation activity and root active absorbing surface area for N uptake and yield formation owing to higher abscisic acid and cytokinin content in the mid- and late growth stages, which improved the seed setting rate, thereby increasing the rice grain yield. These results suggest that NEAs can optimize the morphophysiological characteristics of roots through phytohormone regulation to adapt to different nutrient conditions, thereby promoting N accumulation and yield formation in rice.
