Liquid-liquid extraction and solid phase followed by high-performance liquid chromatography (HPLC) connected with ultraviolet (UV) detection were used for the determination of phytohormones. The parameters influencing performance HPLC-UV method, including composition mobile gradient elution, column temperature, flow rate, wavelength, optimized. This method can simultaneously determine 11 phytoh...

The present investigation was conducted at the technology farmer field of district Shravasti during Kharif seasons 2021 and 2022. Six treatment viz., control (T1), 100% RDF (T2), 50% RDF+Geen Manure (T3), +Zn (T4), FYM+Green (T5), FYM+ Green (T6) were replicated in randomized block design Rice crop variety Rajendra Bhagwati. data recorded revealed that increased Number panicles hill-1, test wei...

Gene mutations conferring herbicide resistance may cause pleiotropic effects on plant fitness. Knowledge of these effects is important for managing the evolution of herbicide-resistant weeds. An Echinochloa crus-galli population resistant to acetolactate synthase (ALS) herbicides was collected in a maize field in north-eastern Italy and the cross-resistance pattern, resistance mechanism and fit...

Previous studies on the effects and interactions of atmospheric carbon dioxide concentration ([CO2]) and air temperatures have shown large differences in growth and yield responses among Asian rice (Oryza sativa L.) cultivars. Far less attention has been focused on rice cultivars commonly grown in the Southern US. This 2-year study was conducted to determine the effects of [CO2] and air tempera...

A single germinated rice (Oryza sativa L) seed can produce 350 grains with the sequential development of 15 leaves on the main stem and 7-10 leaves on four productive tillers (forming five panicles in total), using nitrogen (N) taken up from the environment over a 150-day growing season. Nitrogen travels from uptake sites to the grain through growing organ-directed cycling among sequentially de...
