Effect of Nitrogen and Sulphur Levels on Yield, Economics and Quality of QPM Hybrids under Dryland Condition of Eastern Uttar Pradesh, India

Abstract

The effect of four nitrogen levels {0 kg N ha -1 (N 0 ), 50 kg N ha -1 (N 1 ), 100 kg N ha -1 (N 2 ) and 150 kg N ha -1 (N 3 )} two QPM hybrids {Shaktiman-2 (G 1 ) and Shaktiman-4 (G 2 )} and three levels of sulphur { 15 kg S ha -1 (S 1 ), 30 kg S ha -1 (S 2 ) and 45 kg S ha -1 (S 3 )} in quality protein maize (QPM) production for two years on an experimental field (Sandy clay loam) located at Agricultural Dryland Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India. Each treatment was replicated three times in split plot design. The aim of research was to determine the influence of nitrogen and sulphur levels on yield, quality and economics of QPM hybrids under dryland condition.The significantly highest plant height, leaf area index (LAI), yield, net returns, benefit: cost ratio (B: C), lysine and tryptophan content were recorded with 150 kg N ha -1 (N 150 ) as compared to N 100 , N 50 and N 0 . On average QPM hybrids, Shaktiman-4 produced significantly taller plant (171.68cm), higher LAI (5.49), grain yield (60.54 q ha ), net return (Rs. 39825.09 ha -1 ), B: C ratio (2.26), tryptophan content (0.79%) and lysine content (3.91) than Shaktiman-2× S 15 .

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

“…However, length of cobs with and without husk recorded maximum values in treatment T 11 may be due to optimum availability of nitrogen and sulphur and better translocation of these nutrients to the reproductive parts. These findings are in accordance to those of Rasheed et al, (2004), Jeet et al, (2012), Qahar and Ahmad (2015) and Alam et al, (2003).…”

Effect of Nitrogen and Phosphorus Fertilizers on Growth and Yield of Quality Protein Maize (QPM)

“…Application of phosphorus with 100 kg P 2 O 5 ha -1 produced significantly the taller plants (185.95 cm), maximum LAI (3.17), dry matter production (10572 kg ha -1 ) while these growth parameters was minimum in unfertilized plots and significantly higher than other "p" levels (60, 80 kg P 2 O 5 ha -1 ). The nitrogen has beneficial effect on plant metabolism which affect physiological process of the crop and thereby increases the growth parameters [Jeet et al, 2012]. Likewise effect of high phosphorus levels on growth parameters were probably due to better development of root system and nutrient absorption [Masood et al, 2011].…”

Production Potential and Nutrient Uptake of Quality Protein Maize Hybrid as Influenced by Nitrogen and Sulphur Fertilization

“…The effect of sulphur fertilization appears to vigorous plant as it presence in plant suggest greater availability of metabolites and nutrients ( ). Table 1 Kumar and Bohra 2014and Jeet et al, 2014Kumar et al, 2016Shivran et al 2013 Fig . 1-4 Jeet et al, Shivran et al 2013 Kumar and Bohra 2014 and Rs.80,310 ha ), was found to be higher with application of 150 kg N/ha( ).…”

“…The experiment results at various places indicated that highest grain yield was obtained with applied of 120 kg N/ha ( ). In recent past high yielding single cross hybrid of quality protein maize were Zea mays L. Kumar et al, 2015Jeet et al, 2014Baral et al, 2016Kumar et al, 2015and Kumar et al, 2016Jeet et al,2014Kumar et al, 2016Meena et al, 2011 bread by additional of opaque-2 mutant gene, which improved the lysine and tryptophan and reduced lucine and isoleucine content and produced quality protein with balanced composition of amino acids The quality protein maize has widely adopted for cultivation in developing world to fight malnutrition. The hypothesis of undertaken experiment assumed that nitrogen and sulphur, whose deficits are found in majority of loamy sand soil, can exert an effect on yield ( ).…”
