Description |
A field experiment entitled “Study on weed dynamics in wheat under long term FYM and fertilizer nitrogen application in soil” was conducted during rabi season of 2014-15 at Soil Science Research Farm of CCS Haryana Agricultural University, Hisar. The experiment consisting a combination of two level of FYM (0, 15 t/ha) and three mode of application (kharif, rabi and both kharif and rabi) in main plots whereas, two level of nitrogen (0 and 120 kg/ha) and two weed control treatment (weed free and weedy check) in sub plot was laid out in split-plot design with three replications. Based on the research investigation, it was observed that highest values of crop growth parameters like plant population, LAI and plant height were recorded under the application of FYM 15 t/ha in both the seasons which were significantly superior to FYM 0 t/ha (control) while statistically at par with FYM 15 t/ha applied either in rabi or in kharif. Crop dry matter accumulation, number of tillers/m 2 , yield attributing characters, wheat yield (grain yield, straw yield and biological yield), nutrient uptake by crop were significantly higher where FYM 15 t/ha was applied in both rabi and kharif season as compared to addition of FYM 15 t/ha either in rabi or kharif and control. Similarly, application of 120 kg N/ha significantly increased growth parameter, yield and yield attributes as compared to treatment where no nitrogen was applied. Application of FYM 15 t/ha along with 120 kg N/ha also significantly improved the growth and yield of wheat. The density of A. arvensis and M. Indica decreased with increasing fertility level having highest number of these weeds under control treatments, whereas, density of C. didymus, R. dentatus and miscellaneous weeds, total dry matter of weeds along with uptake and content of NPK in weeds increased with increasing fertility level having highest values of these with application of FYM 15 t/ha along with 120 kg N/ha. Gross returns, net returns and B: C were maximum under application of 15 t/ha in both rabi and kharif season along with 120 kg N/ha and weed free treatment. The combined application of FYM 15 t/ha in both rabi and kharif season along with 120 kg N/ha and weed free treatment gave significantly higher value of growth and yields of wheat and its economic returns. |
