Abstract

It was evaluated the impact of soil and foliar application of zinc on growth and yield of rocket seed. The experimental design was randomized complete block design with three replications. There were 9 treatments including control (No Zn). Soil applied Zn at 7.5 and 15 kg ha-1 (Sowing), Foliar applied Zn at 0.1% and 0.2% (30 and 60 days after sowing), Soil applied Zn at 7.5 kg ha-1 (Sowing) + Foliar applied Zn at 0.1% and 0.2%, Soil applied Zn at 15 kg ha-1 (Sowing) + Foliar applied Zn at 0.1% and 0.2% respectively. The results demonstrated that the maximum growth and yield parameters of rocket seed were obtained by soil + foliar application methods of zinc significantly (P<0.05). The plots receiving soil + foliar applied Zn at 15 kg ha-1 + at 0.2% produced maximum plant population (41.5 m-2), branches plant-1 (15.7), pods plant-1 (587.3), plant height (95.3 cm) and seed yield (2300.0 kg ha-1). Other treatments produced more or less equal plant population, braches plant-1, pods plant-1, plant height and seed yield (kg ha-1). In contrast, minimum growth and yield parameters were recorded in control. Hence, it is concluded that although Zn applied at higher rates either through soil or foliar resulted in higher numerical values, but integration of Soil applied Zn at 7.5 kg ha-1 (Sowing) + Foliar applied Zn at 0.2% (30 and 60 DAS) was observed very economical for getting profitable yield of rocket seed because it showed non-significant results with higher rate treatments.
