ABSTRACT
Two varieties (Early Mustard and S-9) were evaluated against six Zn levels (0, 2, 4, 6, 8 and 10 kg Zn ha-1). Significant improvements in the plant growth, seed yield and oil contents increased with increasing Zn levels. The results revealed that there was a significant improvement in the growth, seed yield and oil content with increasing Zn levels, irrespectively. The highest Zn level of 10 kg ha-1 resulted 216 cm plant height, 10.86 branches plant-1, took 55.66 days to initiate flowering, 574.50 pods plant-1, 17.61 g weight of seeds plant-1, 3.63 g seed index, 2037.20 seed yield kg ha-1 and 36.80 percent oil as the highest output. In case of varieties, S-9 ranked 1st with 216.50 cm plant height, 10.84 branches plant-1, took 56.33 days to initiate flowering, 581.11 pods plant-1, 17.82 g weight of seeds plant-1, 3.66 g seed index, 1960.30 seed yield kg ha-1 and 36.80 percent oil content; while variety Early Mustard resulted 186.56 cm plant height, 9.25 branches plant-1, took 52.72 days to initiate flowering, 484.67 pods plant-1, 14.50 g weight of seeds plant-1, 2.90 g seed index, 1677.90 seed yield kg ha-1 and 35.13 percent oil content. It is suggested that for achieving economically higher seed yields in mustard, the Zn application to mustard may be done at the rate of 8 kg ha-1. Moreover, variety S-9 may preferably grow for obtaining higher seed and oil contact yields.
