Abstract

The experiment was conducted to assess the impactofZn and B application on sunflower growth, yield and oil content in sub-tropical condition. The experiment was laid out in randomized complete block design (RCBD) with twelve treatmentsand replicated thrice. The treatments comprised viz; T1: Without fertilizers (absolute control), T2: RDF (N80P40K40), T3: N80P40K40Zn0.5%, T4: N80P40K40Zn4, T5: N80P40K40B0.2%, T6: N80P40K40B2, T7:N80P40K40Zn0.5%B0.2%,T8: N80P40K40Zn4B2, T9:N80P40K40Zn4Zn0.5%, T10: N80P40K40Zn4B0.2%, T11: N80P40K40B2B0.2%, T12: N80P40K40B2Zn0.5%.From the experimental results recorded it can be concluded that the growth and yield components of the tested crop were significantly influenced by the application of micronutrients as compared to the control (without fertilizer) and recommended dose of fertilizer alone. Among the treatmentsapplication of N80P40K40Zn4B2foundhigher diameter of capitulum (17.72 cm), number of seeds per capitulum (763), seed weight per capitulum(48.98 g), seed yield (2563 kg/ha) and oil yield (1097 kg/ha) of hybrid sunflower (variety KBSH 78) accounting 35.49%,43.25%, 26.66%, 46.50% and 51.32% more than control.

锌和硼营养对杂交向日葵生长、产量和含油量的影响

本试验研究了在亚热带条件下施用锌和硼对向日葵生长、产量和含油量的影响。实验采用随机完全区组设计(RCBD)， 12个处理，重复3次。处理方法包括:T1:不施肥(绝对对照)，T2: RDF (N80P40K40)， T3: N80P40K40Zn0.5%， T4: N80P40K40Zn4, T5: N80P40K40B0.2%， T6: n80p40k40b40b2, T7:N80P40K40Zn0.5% b0.2%，T8: N80P40K40Zn4B2, T9:N80P40K40Zn4Zn0.5%， T10: N80P40K40Zn4B0.2%， T11: N80P40K40B2B0.2%， T12: N80P40K40B2Zn0.5%。从所记录的实验结果可以得出结论，与对照(不施肥)和只施用推荐剂量的肥料相比，施用微量营养素对受试作物的生长和产量构成有显著影响。施用n80p40k40zn4b2处理后，杂交向日葵(KBSH 78)的头状花序直径(17.72 cm)、单株种子数(763颗)、单株种子重(48.98 g)、籽粒产量(2563 kg/ha)和含油量(1097 kg/ha)分别比对照高35.49%、43.25%、26.66%、46.50%和51.32%。
