Effect of Zinc Application on Growth, Yield Parameters, Nutrient Uptake, Yield and Economics of Maize

Abstract

Maize, referred as Queen of cereals is the third most important cereal crop after rice and wheat in India. Maize serves as both human food as well as animal feed and for. Productivity of maize can be increased by proper nutrient management practices. Maize is a zinc responsive crop and found deficient in soils. Zinc as an essential micronutrient that has significant role in basic plant metabolic processes and enhances the growth, yield and quality of maize by stimulating chlorophyll production, photosynthetic activity, nutrient uptake and protein biosynthesis. The zinc application to maize crop either by seed treatment, soil application or by foliar spray by using inorganics have shown significant impact on growth, yield, nutrient uptake, quality and economics from investigations of eminent researchers with increasing trend in productivity. Application of zinc at 20-25 kg ha-1 to maize gave maximum grain yield (7500 kg ha-1) and benefit cost ratio ( 2.4 ) in maize.

Implications of Meteorological Forecasting for Accelerating the Success Rate in Sericulture: New Avenues in Seri-industry: A Review

“…Approximately 45% of the world's total population relies on agriculture for sustaining their livelihood and about 26% of working sector is also associated to the agricultural aspects (W MO, 2001). In addition to major micronutrients (NPK), micronutrients like zinc also play important role for enhancing crop yield (Ariraman et al, 2022). W ith the rampant increase in the world population the demand of agriculture production has also been increased automatically.…”

Detection and molecular identification of a 16SrI group phytoplasma associated with sisal purple leafroll disease

“…The symptoms of SPLD, including purple margins and yellowing and rolling of the leaves, are simi-lar to several other plant diseases caused by viruses (Trenado et al 2011;Li et al 2012;Chen et al 2018;Byarugaba et al 2020), phytoplasmas (Holguín-Peña et al 2007;Sabaté et al 2014;Babaei et al 2019;Gamarra et al 2022), or nutrient deficiency (Yoneda et al 1997;Ariraman et al 2020). In 1964, a disease called "purple leaf tip roll" with similar symptoms to SPLD was reported in sisal in Tanzania; it was suggested to be caused by manganese deficiency (Muller 1964).…”

Effect of Organic Manures on Yield and Quality Characteristics of Pomegranate (Punica granatum L.) Cv. Bhagwa

“…Improvement in nutrient availability [3], soil physical conditions and enzymatic activity have been reported by vermicompost application in fruit crops. Vermicompost is rich in organic carbon, which plays a key role in soil fertility and contains all essential plant nutrients in appropriate proportion.…”
