The objective of this study was to evaluate the performances three cassava genotypes on yield, physiology and morphological traits under different fertilization regimes. A field experiment conducted in a split-plot design for two consecutive seasons Mansa district Luapula Province Northern Zambia highly weathered Chromi-haplic Acrisol soils. Four regimes, control-M3, lime-M1, NPK fertilizer-M4 ...

the aim of this study was to evaluate genotype×environment interaction (gei) of chlorophyll meter readings (spad) of ten durum wheat cultivars, using data obtained from multi-environment trials during two years, at eight locations. stability and genotypic superiority for spad reading was identified using anova and gge biplot analysis. furthermore, the interrelationships among spad reading and o...

A complete module for single-photon counting and timing is demonstrated in a single chip. Features comparable with or better than commercially available macroscopic modules are obtained by integration of an active-quenching and active-reset circuit in complementary metal-oxide semiconductor technology together with a single-photon avalanche diode (SPAD). The integrated SPAD has a 12-microm-diam...

ABSTRACT Powdery mildew is an important disease in tomato, which requires technologies for its control. Homeopathy a science that has been improved as alternative method agriculture. Thus, this study aimed to evaluate the homeopathic medicine Ferrum sulphuricum 6, 12, 24, 48, 72 and 96CH dynamizations on powdery The experiment was conducted from May June 2013 greenhouse, split-split- plot desig...

The first single-photon avalanche diode (SPAD) image sensor fully integrated on flexible substrate is reported. The design consists of an array of 1024 quenched pixels with CMOS readout and addressing circuitries. The flexible substrate was made compatible with sol-gel polymer, which will be used to imprint microlenses by quartz mold to improve fill factor. The SPAD pixel can operate both in fr...

We present a resonant-cavity-enhanced Single Photon Avalanche Diode (SPAD) fabricated on a reflecting siliconon-insulator (SOI) substrate. The substrate incorporates a two period distributed Bragg reflector fabricated using a commercially available double-SOI process. The resonant-cavity-enhanced (RCE) SPAD detectors have peak photon detection efficiencies ranging from 41% at 780nm to 32% at 85...

To facilitate the stable production of rice (Oryza sativa L.) in a changing climate, it is imperative to establish optimal N application rate via growth diagnosis. In this study, field experiments were conducted identify useful indicators white-back grains and protein content rice. During reproductive stages 2018 2019, we applied at different rates recorded soil plant analyzer development (SPAD...

Knowledge of the nitrogen nutrition status vine is essential for long-term management its with aim producing high-quality grapes. Measurement chlorophyll index a fast, non-destructive and relatively inexpensive method that provides good approximation during growing season. Several meters are available on market, each using own measurement unit. With popularizing use meters, interpretation thres...
