To test the effect of N deficiency on maize, we grew Denghai 618 maize without N fertiliser (N0) and with N fertiliser (N1) and then measured parameters related to photosynthesis (Fig. However, amount of nitrogen to be applied for maize plant depends upon maize variety, soil type, crop fertility status, location and yield. Although a large number of studies have identified the expression changes of microRNAs (miRNAs) under N stress in several species, the miRNAs expression patterns of N-deficient plants under N resupply remain unclear. Maize (Zea mays) plants exhibit altered carbon partitioning under nitrogen (N) deficiency, but the mechanisms by which N availability affects sugar export out of leaves and transport into developing ears remain unclear.Maize was grown under field conditions with different N supply. Tel: +254 724255370/ 724255371 N deficiency effects on grain weight, plant weight, harvest index, leaf area and photosynthetic traits were studied in the field for six maize hybrids released during the … The demand of nitrogen fertilizer is greater than that of the other nutrients. Maize is an important crop in the world, nitrogen stress severely reduces maize yield. Citation: Nazir M, Pandey R, Siddiqi TO, Ibrahim MM, Qureshi MI, Abraham G, Vengavasi K and Ahmad A (2016) Nitrogen-Deficiency Stress Induces Protein Expression Differentially in Low-N Tolerant and Low-N Sensitive Maize Genotypes. Affected plants show stunted, sparse growth. 1 If nitrogen deficiency occurs at tasseling and silking stages may significantly affect crop failure. Front. Reasons Nitrogen deficiency Sulphur deficiency can cause similar chloroses but starts on the younger leaves, whereas paling due to N deficiency is detectable on older leaves first Different levels of nitrogen deficiency vs control (from left to right). Plant Sci. 1D–F) at the tasselling stage (VT), at 20 days after the tasselling stage (20 DAT), and at 40 DAT.We observed a significant decrease in the net photosynthetic rate (Pn) of ear leaves in plants … Nitrogen Deficiency in Maize: II. Carbon‐Nitrogen Interaction Effects on Kernel Number and Grain Yield. 7:298. doi: 10.3389/fpls.2016.00298 Potential Physiological Frameworks for Mid‐Season Field Phenotyping of Final Plant Nitrogen Uptake, Nitrogen Use Efficiency, and Grain Yield in Maize, Crop Science, 10.2135/cropsci2012.05.0305, 52, 6, (2728-2742), (2012). Plant growth, sugar movement, and starch turnover in source or sink tissues … The primary objective of this study was to identify miRNAs in response to nitrogen … The leaves turn uniformly pale green. Abstract. The present study was conducted to determine effective spectra ranges and significant component images of RGB intensities which restrict ineffective data to be processed in identifying N and K deficiency symptoms through image mining, … Low or high pH soils ... Maize: 200-400 lbs YaraVera® Amidas® 40-0-0/acre depending upon yield expectations and soil test. Yara East Africa Ltd. 12th floor, Crowne Plaza Hotel Annexe Longonot Road, Upper Hill. The leaves turn uniformly pale green. Nitrogen deficiency made worse by. Maize root samples from plants grown in nitrogen deficiency experienced an immense loss of methylated cytosines, especially in the symmetrical contexts, while phosphorus-deficiency samples showed only a much smaller loss in the symmetrical contexts, providing evidence for a nutrient-specific adaptation in DNA methylation. Therefore, the effects of N deficiency on the mass of plant and grain, harvest index, leaf area and photosynthetic traits were studied for six maize hybrids released during the past 50 years to explore the related physiological mechanisms that lead to the different responses to nitrogen deficiency of the newer and older hybrids. PO Box 50949-00200, City Square Nairobi – Kenya. Affected plants show stunted, sparse growth. Nutrients namely nitrogen (N) and potassium (K) management is an important agronomic practice to attain higher yield.
