PENGARUH JENIS TANAH TERHADAP PERTUMBUHAN DAN HASIL TANAMAN JAGUNG (Zea mays L.) VARIETAS PULUT SULAWESI
Abstract
A purpose of this research was the effect of soil type and determine the type of soil that is most appropriate for the growth and yield of corn (Zea mays L.) varieties of pulut. This research was conducted with experimental method in field experiment using a Completely Randomized Design (CRD) with single factor and consisting of 4 treatments that is corn (Zea mays L.) varieties of pulut planted on Regosol soil (S1), Grumusol soil (S2), Latosol soil (S3), and Mediterranean soil (S4). The Parameters observed included plant height, leaf number, root length, root fresh weight, root dry weight, leaf area, fresh weight of plant, dry weight of plant, net assimilation rate, plant growth rate, fresh weight of cobs weighted, fresh weight of cob without the cob, diameter of cob, long ear of corn cob, number of rows of seeds, weight of 1,000 seeds, potential yield of plants. The results showed that the treatment of soil types gave potential results in the treatment of hill-sand Regosol soil of 2.6 tons, Latosol soil of 2.46 tons, Grumusol soil of 2.05 tons, and Mediteran soil of 2.04 tons. Various types of soil tend to produce relatively the same results, so that various types of soil are said to be appropriate in the growth and yield of corn (Zea mays L.) varieties of pulut.
