Effect of Nitrogen and Zinc on Growth and Yield of Maize (Zea mays L.)

Abstract

The experiment was laid out on the effect of nitrogen and zinc on growth and yield of maize (Zea mays L.) at Research Farm of the Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab, India during kharif (July to October) season of 2017. The experiment was laid out in randomized block design three replication with eight treatments. The soil of the experimental field was Gangetic alluvial having clay loam texture with pH 7.5. It was moderately fertile, with available nitrogen (285.24 kg ha-1), available phosphorus (26.15 kg ha-1), available potassium (250.84 kg ha-1) and available zinc (1.42 mg kg-1). The maximum growth parameter viz. plant height (cm), LAI (%), dry matter accumulation (g) and the highest yield attributes and yield parameters viz., number of cob-1, length of cob (cm), test weight (g), number of grain cob-1, grain yield (q ha-1), stover yield (q ha-1), biological yield (q ha-1) and harvest index (%) was recorded at 30, 60, 90 DAS and at harvest stage with the application of nitrogen @150 kg ha-1++zinc @30 kg ha-1 which was at par with the treatments namely; nitrogen @150 kg ha-1++zinc @15 kg ha-1 and nitrogen @150 kg ha-1. All the treatments significantly influenced the growth and yield attributes as compared to control. The maximum net returns (` 89977 ha-1) and benefit:cost ratio (1.58) has been recorded with application of nitrogen @150 kg ha-1++zinc @30 kg ha-1.

Yield, profitability and agronomic efficiency of nitrogen in rainfed maize with complementary foliar fertilization of Zn and Mo

“…En la Tabla 4 se presenta detalladamente los resultados del análisis del beneficio económico neto de la fertilización complementaria con Zn y Mo. Durante la temporada 2020, la fertilización complementaria con Zn y Mo alcanzó el mayor beneficio económico total del maíz y neto de la Singh et al (2021), alcanzaron mayores retornos económicos cuando la fertilización nitrogenada del maíz fue complementada con aplicaciones foliares de Zn. El mayor rendimiento, eficiencia agronómica de nitrógeno y beneficios económicos alcanzados con la fertilización edáfica complementada con nutrición foliar de Zn y Mo, en relación a la fertilización edáfica convencional, pueden relacionarse con las funciones fisiológicas que desempeña en Zn en especies C4 como el maíz, y el rol del Mo en el metabolismo del nitrógeno.…”

Impact of Nutrient Management on Soil Chemical Properties and Maize (Zea mays L.) Yield

“…Singh et al [25] studied the effect of nitrogen and zinc on growth and yield of maize and concluded that higher grain yields (66 q ha -1…”

Effect of sulphur nutrition on growth parameters, yield parameters, yield, nutrient uptake, quality and economics of maize: A review

“…Dhananjaya and Basavaraj (2002) [10,11] documented that application of sulphur at 45 kg ha -1 increased the plant height compared to no application. Ram et al, (2003) [38,39,51] registered significant increase in plant height with application of sulphur at 60 kg ha. Maurya et al, (2005) [25] observed a significant increase in growth parameters such as height of the plant, no.…”

“…Rahul (1975) [37] concluded that application of sulphur at 90 kg ha -1 gave maximum yield in maize compared to control. Singh et al, (1987) [8,13,14,18,20,25,32,39,43,48,51,53] registered a significant increase in maize yield with application of sulphur at 22.4 kg ha -1 significantly increased the maize yield of maize up to 43.4% over control. Leary and Rehm (1990) [21] reported that sulphur application at 10 kg ha -1 gave higher yield than lower and higher levels from his study.…”
