An increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(Prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. Information on this subject is limited at the present time. In search of superior nectarines, a trial was conducted to study growing degree days (GDD), ful...

Herbicide resistance is an example of plant evolution caused by an increased reliance on herbicides with few sites of action to manage weed populations. This micro-evolutionary process depends on fitness, therefore the assessment of fitness differences between susceptible and resistant populations are pivotal to establish management strategies. Loose silky bentgrass (Apera spica-venti) is a ser...

Abstract Yellow nutsedge is one of the most widely distributed and troublesome weeds in world. Field greenhouse studies were conducted to optimize strategies for increased yellow control turfgrass with halosulfuron sulfentrazone. In field study perennial ryegrass mixture, single or sequential applications (3 wk after initial) sulfentrazone made on June 3, 23, July 15, August 5 2013, 2014, 2015,...

A forward estimate of mango (Mangifera indica L.) harvest timing is required for farm management (e.g., organization labour and marketing). This can be based on accumulated growing degree days (GDD) from an early stage flowering to fruit maturity, with maturity judged a destructive assessment flesh colour dry matter content. The current study was undertaken improve GDD targets Australian cultiv...

Abstract Two species of cleavers, Galium aparine L. and spurium L., are known to inhabit croplands in western Canada. The latter is the more abundant two species. An increased abundance these over most recent decades warrants a comprehensive understanding their developmental phenology cause this increase. This study aimed identify base temperature emergence characteristics spp. across different...

Background: Selection of a suitable planting time is one the key factors for obtaining desirable rice grain yield. This study focuses on effect date agronomic traits and provides useful information an optimal window to maximize yield Bangabandhu dhan100 in cold-prone Rangpur region, Bangladesh Methods: The was conducted at regional station farm Rice Research Institute from October 2021 June 202...

Forecast of tree fruit yield requires prediction harvest time size as well number. Mango (Mangifera indica L.) mass can be estimated from correlation to measurements length (L), width (W) and thickness (T). On-tree individually tagged were undertaken using callipers at weekly intervals until the past commercial maturity, judged growing degree days (GDD), for mango cultivars ‘Honey Gold’, ‘Calyp...

Unfavorable weather conditions and lack of appropriate farm machinery often delay N application. This results in nitrogen (N) deficiency during the vegetative early reproductive growth stages winter wheat. The objective this study was to evaluate impact application timings (from tillering flag leaf stages) on wheat grain yield protein. conducted across 12 site–years Oklahoma, US. treatments inc...

velvetleaf (abutilon theophrasti) is one of the most important weeds of soybean fields in golestan province. a field experiment was conducted in gorgan agricultural research station in 2007 to determine the critical period for velvetleaf control in williams soybean (glycine max (l.) merr.) cultivar using a randomized complete block design with 4 replications. treatments were included two sets o...

Genotype, environmental temperature, and agronomic management of parents influence seed yield in three-way cross hybrid maize production. The objective this research was to generate information on the production six hybrids their progenitors, adapted tropical lowlands. Data days to—and duration of—flowering, distance spike stigmas, five female single crosses male inbred lines were recorded for ...
