Impact of pre-sowing red laser irradiation of corn seeds on quality and quantity of harvest yield

As the population increases, more people need to be fed. In order find a physical method that influence corn production, this work is dedicated evaluating impact of pre-sowing red laser irradiation (Zea mays L.) seeds on harvest yield. The aim was analyze radiation seeds, quantity and quality yield, large-scale open field production. It hypothesized at least one treatment could improve crop radiation, diode 660 nm with power 100 mW used, two densities were used (D1: 2 cm-2 D2: 4 cm-2), applied during exposure times (T1: 15, T2: 30, T3: 60 T4: 120 s) control group without (C). A random arrangement in x factorial scheme, totaling 8 treatments control, four replications. data subjected an ANOVA means compared Tukey test (HSD; p ≤ 0.05). D2-T4 produced most significant concerning improving yield by 19±1% (3 t ha-1), cob length 18±1%, diameter 22±3%, weight (16±2%) kernels size (14±2%). We also negative effects D2-T1 decreased around 16±1% (2.24 ha-1). results show way include technique as can increase or decrease Keywords: Cob length; Maize; field; Thousand kernel weight.
