Interaction Effects of different doses of Sulphur and Zinc with NPK on Growth of Yellow Mustard (Brassica compestris L.)

The field experiment was carried out at Department of Soil Science, Sam Higginbottom Institute of Agriculture, Technology and Science, Allahabad, India during rabi season. The experiment was laid out in 3×3 factorial randomized block design with 9 treatments in three replications. It was observed that the growth characters in treatment T9 (@ 45 kg Sulphur ha-1 + 5.5 kg Zinc ha-1) in respect to different day’s intervals i.e. 25, 50, 75 and 100 days after sowing (DAS). Plant height was 2.25, 26.26, 104.88 and 105.40 cm found to be significant at 25 and 75 DAS but non-significant at 50 and 100 DAS, no. of leaves plant-1 were 6.31, 10.97, 15.45 and 11.22 found to be non-significant at 25 DAS but significant at 50, 75 and 100 DAS, maximum dry weight of plant (g) was recorded as 0.99 in (T5), 19.49 in (T9), 19.62 in (T5) and 21.37 (T5) respectively at 25, 50, 75 and 100 DAS was found significant at 25, 75 and 100 DAS, whereas found non-significant at 50 DAS, maximum no. of primary branches plant-1 was 11.33 found to be significant. Highest no of secondary branches were found in T8 (@ 45 kg Sulphur ha-1 + 2.75 kg Zinc ha-1) which was 16.77 and found to be significant. However, since these findings are based on one year experiment and therefore, further research may be conducted to substantiate it under Allahabad agro climatic conditions.
