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 ...

Waterlogging is an important abiotic stress constraint that causes significant yield losses in maize grown throughout south and south-east Asia due to erratic rainfall patterns. The most economic option to offset the damage caused by waterlogging is to genetically incorporate tolerance in cultivars that are grown widely in the target agro-ecologies. We assessed the genetic variation in a popula...

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...

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...

The elevating temperature makes heat stress one of the major issues for wheat production globally. To elucidate genetic basis and map tolerance QTLs agroecology State Bihar under NEPZ, a set 166 doubled haploid lines (DHLs) derived from cross between PBW343/IC252874 was used. population evaluated normal sown (NS) late (LS) conditions two cropping seasons. canopy (CT) showed positive correlation...

Silicon, which is widely used in different fields, has been plant production vivo and vitro studies recent years. Especially studies, it seen that its effect on growth development examined. In this study, the of three silicon sources their four concentrations micro-propagation 140 Ru grape rootstocks was investigated. as explants one-node micro cuttings rootstock MS (Murashige Skoog) nutrient m...

the objectives of this study were to evaluate the effects of nitrogen fertigation frequency on lint yield, lint properties, chlorophyll content (spad readings), and the photosynthesis rate (pr) of cotton. this study was carried out in the southeastern anatolia region of turkey in 2011 and 2012 with drip-irrigated cotton. the maximum lint yield (1,856 kg ha-1) was obtained with one lateral for e...

in order to study the effects of conventional and conservation tillage with management residue on wheat physiological properties, a field experiment was conducted in 2013-2014 at mashhad agricultural and natural resources research center of razavi khorasan province. this experiment was carried out as split plot design based on a randomized complete block design with three replications. main plo...

Hydroponic experiment was conducted to investigate the sole and combined effects of cadmium and salinity on growth and photosynthesis of Brassica napus (cultivar Abasin) and Brassica juncea (cultivar NIFA-Raya). Cadmium (as CdCl2; 3 and 6 μmol L) and NaCl (100 and 200 mM) were added either alone or in combination in Hoagland solution along with non-treated controls. Cd and NaCl treatments impos...

We present a novel method for the robotized probing of plant leaves using Time-of-Flight (ToF) sensors. Plant images are segmented into surface patches by combining a segmentation of the infrared intensity image, provided by the ToF camera, with quadratic surface fitting using ToF depth data. Leaf models are fitted to the boundaries of the segments and used to determine probing points and to ev...
