Influence of seaweed sap on growth yield and nutrient uptake of Maize Zea mays L cultivars

Abstract

Agronomic research has focused on multiple management interventions such as newlineplant density, mineral fertilization, water management, resource conservation, and diverse newlinemaize-based cropping systems across different ecologies in order to fully exploit the newlinepotential of better cultivars. Maize is a heavy feeder of nutrients, there is a significant newlinedemand for fertilizer in maize-growing areas with hybrid cultivar. The lack of crop newlinenutrients in adequate levels and forms is one of the key crop productivity restrictions in newlinethe developing countries. In this case, seaweed sap were good choice with inorganic newlinefertilizer, chemical fertilizer which degrades soil health and the ecosystem the use of newlineorganic and natural fertilizers that are readily available help to maintain soil fertility in newlinethe intensive cropping systems. Hence, it was realized to evaluate promising maize newlinecultivars and seaweed sap foliar application under condition to boost maize production. newlineKeeping this in view, an experiment entitled Influence of seaweed sap on growth, yield newlineand nutrient uptake of maize (Zea mays L.) cultivars was carried out during the zaid newlineseason in two successive years of 2020 and 2021 at the Crop Research Farm, newlineDepartment of Agronomy, Sam Higginbottom University of Agriculture, Technology newlineand Sciences, Prayagraj. The experiment was laid out in Split Plot Design along with two newlinefactors viz., four maize cultivar (VMH-27, VMH-53, VLMH-57 and VLQPMH-59) as newlinemain plot and two seaweed (Kappaphycus sp. and Sargassum sp) sap at different newlineconcentration (5%, 7.5% and 10%) as sub-plot factor treatment along with one water newlinespray and their combination of 28 treatments replicated thrice. Treatments were randomly newlinearranged in each replication, divided into eighty four plots and results of the investigation newlineare summarized below. newlineResults revealed that the productivity of maize was influenced by cultivars and newlineseaweed sap foliar concentration. On pooled analysis of both the year experiment, it was newlineclearly evaluated that among cultivars VLMH-57 produced higher
