Abstract
A field experiment was conducted during rabi season of 2015-16 and 2016-17 at Panwari village of Agra district to study the response of wheat (Triticum aestivum L.) to sulphur under balanced and imbalanced fertilizer application. Treatments consisted of application of balanced (NPK) and imbalanced (NP and NK) fertilizer application along with sulphur. The experiment was laid out in a randomized block design with six treatments and three replications. Results revealed that balanced fertilizers (NPK) application proved superior in respect of growth yield and utilization of nutrients over imbalanced fertilizer application. The application of NPKS (150 kg N + 60 kg P2O5 + 40 kg K2O + 30 kg S ha-1) significantly increased the plant height (95 cm) length of ear (103.cm grain/ear (51.8), ear/m2 (50.8) and test weight (40.4g) compared with other treatments. Significantly higher grain (56.39 q ha-1) and straw (71.15 q ha-1) yield were recorded with NPKS treatment over other treatments. Application of NPKS significantly increased the uptake of nitrogen by wheat crop over other treatments Protein content in grain (13%) and protein yield (733.0 kg ha-1) were also higher with NPKS treatment. The lowest values of all these parameters were recorded under NK treatment. However, NK and NP treatments statistically at par in respect of growth and yield of wheat crop.
