This study was aimed to determination of seed treated humic acid effects to yield and some yield characteristics of corn plant (Zea mays L. indentata) as grown second crop conditions. Study was set up according to randomized complete blocks experimental design with 3 replicates under Harran Plain conditions in 2012, Sanliurfa, Turkey. Motril hybrid corn variety was used as a plant material. Humic acid seed treatments were 0 (control), %2.5, %5, %7.5, %10, and %12 humic acid concentrations. Humic acid concentrations were applied to corn seed before sowing. Some yield and yield characteristic of corn plant such as tassel flowering duration, plant height, leaf number per plant, grain weight of ear, thousand kernel weights and grain yield were evaluated in the study. As a result of research; statistical significant differences were seen among humic acid seed treatments at tassel flowering duration and leaf number per plant (P≤0.05). Also, humic acid seed treatments were significant at grain weight of ear, thousand kernel weights and grain yield (P≤0.01). Tassel flowering duration decreased with humic acid seed treatment whereas leaf number per plant, grain weight of ear, thousand kernel weights and grain yield values increased with humic acid seed treatment. The highest values were found in % 7.5 humic acid seed treatment

Impact of Vermicompost to Dent Corn (Zea mays L. indentata)

Corn is the most cultivated cereal plant in the world after wheat and rice. Grain yield of corn depends of genetic factors but the application of various nutrients to the soil is also effective for increasing yield. Vermicompost is used for increasing grain yield at the some plants recently. Worm fertilizer which is known as vermicompost is an organic fertilizer which fertilizer is digested by worms and converted into fertilizer. Vermicompost includes all enzymes, soil antibiotics, vitamins, growth hormones and humic substances for plant growth. In this study, it was aimed to determine the effects of various levels of vermicompost on the yield and some characteristics of corn plant. The study was conducted in 2017 growing season of Harran Plain second crop conditions. In the study, DKC-6120 corn variety was used as plant material. Different levels of vermicompost were applied as a supplementary to standard inorganic fertilizer. Vermicompost dosages were 0, 50, 100, 150, 200 kg da-1. The research was conducted according to the randomized complete block design with three replicates. Row spaces were 70 cm and intra row space was 20 cm. Seeds sown in 2-4 cm depth. Each parcel was built from 14 m2. In the study, hectoliter weight, ear weight, ear diameter, ear length, grain numbers of ear and grain yield values were determined. The highest hectoliter weight (80.37 g), ear weight (302.67 g), ear length (23.33 cm), grain number of ear (802.47 number) and grain yield (976.67 kg da-1) values were obtained from 200 kg da-1 vermicompost applications while the lowest values were seen at control parcels (77.87 g, 260 g, 21.79 cm, 710.27 number, and 895.24 kg da-1, respectively).
