Effects of Nitrogen and Sulfur Fertilizers on Nitrogen Content in Soil, Ear Leaf, Flag Leaf and Grain of QPM Maize Varieties at Samaru Zaria

Abstract

Field trial was conducted in 2006, 2007 and 2008 wet seasons, at the Institute for Agricultural Research Farm, Samaru in the Northern Guinea savanna of Nigeria to determine the effects of nitrogen and sulfur fertilizers on nitrogen uptake of quality protein maize (QPM) varieties. Treatments consisted of four (4) rates each of nitrogen (0, 60,120 and 180 kg N/ha) and sulfur fertilizer (0, 5, 10 and 15 kg S/ha) and two QPM varieties (Obatampa and EV -99), laid out in a split plot design with variety and nitrogen in the main plots and sulfur in the sub plots and replicated three times. The results show that varietal differences influenced soil and flag leaf nitrogen in 2006 and 2008 respectively. Nitrogen application did not affect nitrogen content in the soil at all the three years of the trial. However, Ear, Flag and Grain nitrogen content was affected by nitrogen application. Sulfur application influenced soil, ear leaf, flag leaf and grain nitrogen content in different years of the study.

Effect of NPKS and Zn Fertilization on, Growth, Yield and Quality of Baby Corn-A Review

“…Srinivasarao et al, (2010) significantly higher sulphur uptake with increasing levels of sulphur application up to 20 kg S ha -1 . Application of increasing levels of sulphur up to 15 kg S ha -1 produced significantly higher N content in flag leaves of maize (Jaliya et al, 2012). Jeet et al, (2012) noticed that application of 45 kg S ha -1 significantly increased N, P, K and S content over 15 kg S ha -1 but it remained at par with 30 kg S ha -1 .…”

Effects of phosphorus and sulphur on dry matter yield of maize (<i>Zea mays</i>) in some soils at Abeokuta, Ogun State, Nigeria

“…It has beneficial effects by lowering soil pH and improving physical condition of the soil (Choudhary and Das, 1996). Increasing level of S progressively enhanced the average total N uptake by maize and this increase in N uptake may be attributed to increase in N content of plant and dry matters yield due to increasing S levels (Jaliya et al, 2012). Ray and Mughogho (2000) reported that S is a secondary nutrient taken up by most grain crops in amount namely 10 to 30 kg ha -1 .…”

Growth, Yield-Related Traits and Yield of Lowland Maize (Zea mays L.) Varieties as Influenced by Inorganic NPS and N Fertilizer Rates at Babile, Eastern Ethiopia

“…is clearly showed that the application of 150 kg NPS with 87 kg N could be optimum growth resource to assimilate more photosynthates to properly fill the kernels. On the other hand, the presence of adequate N and S nutrients within the plant tissue plays a great role in biochemical processes, which contributed to more photosynthetic activities and thus resulted in the production of optimum assimilate for subsequent translocation to the plant parts for economic grain yield [43]. Besides, an increase in 1000-grain weight might be due to enhancement in source efficiency as well as sink capacity [44].…”
