Yield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
متن کاملResponse of Maize to Nitrogen Application Methods and Row Configuration
A field study was conducted on sandy clay loam soil to evaluate the impact of row spacing and N application method on the productivity of maize (Zea mays L.). The experiment was conducted using four row spacings (60 cm spaced single rows, 90 cm spaced double row strips, 90 cm spaced single rows and 135 cm spaced double row strips) and two methods of nitrogen (N) application (broadcast and band ...
متن کاملDifferences in maize physiological characteristics, nitrogen accumulation, and yield under different cropping patterns and nitrogen levels
Intercropping and N fertilization play an important role in increasing crop yield. In order to further understand the advantage mechanism of intercropping and the effect of increasing N application on the advantage effect of intercropped crop, a field experiment was conducted to investigate the effects of different cropping patterns (i.e. M, maize monoculture; I1, maize-cotton intercrop; I2, ma...
متن کاملCorrelations between Nitrogen Content and Multispectral Image of Greenhouse Cucumber Grown in Different Nitrogen Level
Short fruit cucumber was chosen as object. Different nutrition conditions were applied to cultivate plants.CCD camera with special filters was used to gather images. Correlation analysis results shows that four indexes, CNDVI, GNDVI, NDGI and NDVI, had much higher correlation with nitrogen content of cucumber leaves. LS-SVM algorithm was proposed to construct models between vegetation indexes a...
متن کاملOptimum Leaf Removal Increases Nitrogen Accumulation in Kernels of Maize Grown at High Density
Increasing plant density is one of the main approaches of achieving higher yields for modern maize crop. However, there exists leaf redundancy for high-density maize, and leaves of the upper canopy shade more competent leaves at the middle strata. In a two-year field experiments, Jinhai5, a semi-compact corn cultivar, was grown at a density of 105,000 plants ha-1 grown until 3 days after silkin...
