in order to investigate the effects of nitrogen fertilizer on yield and yield component of potato, (solanum tuberosum l.) and researching for direct and indirect effects of some important agronomic traits, an experiment was conducted based on randomized complete blocks design with three replications at the agricultural research station, ferdowsi university of mashhad, iran, during 2008. chlorop...

Prolonged drought of cowpea at the seedling stage can affect survival and productivity. This study sought to evaluate genotypes for their resistance seedling-stage stress. Fifteen were used in this study. The experiment was a factorial arranged Completely Randomized Design with three replications. Drought stress imposed 4 weeks after full expansion first trifoliate leaf. Soil Plant Analysis Dev...

In many parts of the world, limited water and climate change are significant challenges to future peanut production, much work remains in developing heat- drought-tolerant cultivars. To this end, we evaluated 21 accessions U.S. mini-core under water-limited conditions 2018 2019 Oklahoma, Texas, Virginia. These were identified as potentially exhibiting phenotypic extremes for ten drought stress ...

The effects of potassium fertilizer (K2SO4) levels K0, (0), K1,(150) and K2,(250 kg/ha) in two species of Brassica napus (Hyola 401 Hybrid) and Brassica juncea (landrace cultivar), under three irrigation regimes, control (irrigation after 50%,), moderate stress, (irrigation after 70%), and severe stress (irrigation after 90% soil water depletion) were studied in a factorial experiment laid out ...

The objective of this experiment was to study of water relations and chlorophyll in different wheat genotypes and their correlations with grain and biological yields. 21 genotypes of bread wheat were compared in a field experiment as randomized complete blocks design with four replications. The results showed that relative water deficit, relative water loss, excised leaf water retention, cell m...

Iron deficiency chlorosis (IDC) under calcareous and alkaline soils is a significant abiotic stress affecting the growth yield of peanut. In this study, genomic regions governing IDC tolerance were mapped using recombinant inbred line (RIL) population derived from TMV 2 (susceptible to IDC) 2-NLM (tolerant IDC), which was phenotyped during rainy seasons 2019 2020 in iron-deficient plots. The be...

Ex situ conservation plays an important role in maintaining global plant biodiversity and protects thousands of wild plants. Plant botanical gardens is part ex conservation; however, little attention has been given to whether ecophysiological traits change goals are reached following conservation. In this study, tree shrub plants were selected from Shanxi, Beijing China Botanical Garden, with g...

The first signal model for a single photon avalanche diode (SPAD)-array communication receiver multilevel modulation schemes is reported. This paper proposes novel, generalised SPAD array and noise both digital analogue, synchronous asynchronous readout arrays, which includes the competition between input photons, dark counts after-pulsing counts. With this contention model, signals including v...

Water limitation is a major yield limiting factor in groundnut and transpiration efficiency (TE) is considered the main target for improvement, but TE being difficult to measure it has mostly been screened with surrogates. The paper re-explore the contribution of TE to grain yield in peanut by using a novel experimental approach in which TE is measured gravimetrically throughout the crop life c...
