Rice is China’s main crop and its output accounts for 30% of the world’s total annual rice production. growth status closely related to chlorophyll content (called Soil Plant Analyzer Development (SPAD) values). The determination a SPAD value great significance health rice, agricultural irrigation regulated fertilization. traditional measurement method not only time-consuming, laborious expensi...

Heat stress is a major production constraint of wheat in South Asia, particularly the Gangetic plains India and Bangladesh. The leaf chlorophyll status key determinant for high rate photosynthesis under stress. present experiments included 238 genotypes 2016-2017 321 2017-2018 optimum heat conditions. Subsequently, set 100 selected on basis susceptibility index was evaluated 2018-2019 condition...

Late blight caused by Phytophthora infestans is a destructive disease in potato production, which can lead to crop failure severe cases. This study combined visible/near-infrared (Vis/NIR) spectroscopy with machine learning (ML) and chemometric methods for rapid detection of late blight. The determination severity was accomplished two directly or indirectly based on differences reflectance. One...

ELECT A fast tracking system is demonstrated that is based on single laser illumination and a few single-pixel single photon avalanche diode (SPAD) detectors that improves on the previous tracking of non-line-of-sight motion by a factor of 300 in laser power. With an average illumination power of only 2 mW, a 15 cm ×15 cm object located up to 2.5 m away is tracked whilst outside of the direct l...

A field experiment was conducted at Bangladesh Agricultural Research Institute (BARI) farm, Gazipur to evaluate the effect of foliar application of potassium orthophosphate on grain yield and kernel quality of wheat under the terminal heat stress imposed by late sowing for two consecutive years (2008-09 and 2009-10). Five combinations of foliar applications of potassium orthophosphate and Tilt ...

There is a growing interest in photoplethysmography (PPG) for the continuous monitoring of cardio-respiratory signals by portable instrumentation aimed at early diagnosis cardiovascular diseases. In this context, it conceivable that PPG sensors working different wavelengths simultaneously can optimize identification apneas and quantification associated heart-rate changes or other parameters dep...

To impart sustainability to modern intensive farming systems, environmental pollution caused by nitrogenous fertilizers in needs be reduced optimizing their doses. estimate the grain yield and nutrtional quallity of wheat, normalized difference vegetation index (NDVI) chlorophyll content (SPAD) are potential screening tools identify N deficiency screen out promising cultivars. The two-year fiel...

Abstract Wheat productivity is severely hampered by drought, owing to its negative impacts on crop growth and development. For obtaining better yield, the of drought should be ameliorated. Therefore, current study scrutinizes potential different silicon (Si) forms minify drought-associated reduction in yield changes nutrients accumulation. In a strip plots design based randomized complete block...

Oat has been gaining renewed interest due to its role in a healthy human diet, animal feed, and as source of high value compounds with industrial applications. Nitrogen fertilization planting density are two the most important crop management practices that affect formation yield components final oat. A 2 year 3 × 5 factorial field experiment was conducted investigate effects nitrogen (N) ferti...

In recent years, there has been a growing interest in exploring the application of single-photon avalanche diode (SPAD) optical wireless communication (OWC). As photon counting detector, SPAD can provide much higher sensitivity compared to other commonly used photodetectors. However, SPAD-based receivers suffer from significant dead-time-induced non-linear distortion and signal dependent noise....
