Increasing atmospheric temperature can significantly reduce global wheat productivity; despite a mounting demand for grain supplies. Developing genotypes with superior performance under current and future hot climates is key challenge breeders. Multidimensional tools have supported plant breeders in increasing the genetic stability rate of agro-physiological indices that influence productivity....

Slotted Meander-Line Resonator (SMLR) is implemented by creating defect in the microstrip structure. This resonator is designed to block the surface current at the resonant frequency of the two patch antennas coupled along H-plane operating at 3.6 GHz. The proposed configuration provides an improvement in isolation by 10 dB (measured value) with a reduced edge-to-edge spacing of 7 mm (λ0/9). Th...

Two multivariate models were compared to assess their yield predictability based on long-term (1980–2021) rice and weather datasets over eleven districts of Karnataka. Simple multiple linear regression (SMLR) artificial neural network (ANN) calibrated (1980–2019 data) validated (2019–2020 data), yields forecasted (2021). An intercomparison the revealed better with ANN, as observed deviations sm...

The ability of hyperspectral image (HSI) data to provide estimates of soil electrical conductivity (ECa) and soil fertility levels without requiring extensive field data collection was investigated. The relationships between HSI spectral reflectance signatures and soil properties were analyzed to evaluate the usefulness of HSI for quantifying within -field spatial variability. Bare soil images ...

To extract the sensitive bands for estimating the winter wheat growth status and yields, field experiments were conducted. The crop variables including aboveground biomass (AGB), soil and plant analyzer development (SPAD) value, yield, and canopy spectra were determined. Statistical methods of correlation analysis, partial least squares (PLS), and stepwise multiple linear regression (SMLR) were...
