Effect of population level of various hybrid corn strains on growth and yield

[摘要] The success of plant breeding efforts is the availability of genetic diversity in the population so that people can choose what is preferred due to limited optimal land by utilizing sub-optimal land. The level of plant population is carried out to obtain information about a prospective maize variety that has a high productivity in land with limited / minimal level of sunlight. The higher level of plant population means the lower the reception of light by plants, therefore we need a variety that is shade resistant. The purpose of this study was to determine the effect of the population level of each unit area on various shade-resistant lines with high productivity which is expected to be applied on intercropping land (plantations / forests) that have high shade levels. The study was conducted at Cereals Plant Research Institute, Maros in August - November 2016. The study used a randomized block design in the form of a split plot with 3 replications. The main plot is the plant population, which is a medium population of 70 cm x 20 cm (population 71,428 plants/ha) and a population of height 70 cm x 15 cm (population 95,238 plants/ha). As subplots were 10 prospective varieties of hybrid corn strain. The results showed that the shade resistant strain of 70 x 15 cm plant spacing highest yields of 1044-9 x 1027-11 (7.75 t/ha) and 70 x 20 cm spacing yield (t/ha) the highest CY 15 x MAL 03 (10.07 t/ha).
