The objective of this study was to determine the effects on grain yield of growing cultivars in mixtures of different proportions. Two maize (Zea mays L.) hybrids, Pride 116 and United 106, were grown for 2 yr in pure stand and in seven mixtures of different proportions (7:1, 6:2, 5:3, 4:4, 3:5, 2:6, 1:7) at plant densities of 61 500, 99 400, and 136 000 plants per hectare. The total number of mixture combinations was 42, i.e. 2 years × three densities × seven proportions. All but one mixture yielded as expected based on the yield of component hybrids in pure stand. The higher yielding hybrid (United 106) yielded significantly less grain per plant in mixtures than in pure stand. The lower yielding hybrid (Pride 116) yielded more in mixtures than in pure stand, although the difference was not significant. These data support previous observations that the ability of a hybrid to yield in pure stands is not necessarily related to its ability to yield in mixtures. High plant densities appear to enhance the likelihood of interactions occurring among hybrids. For United 106, the number of proportions yielding less grain per plant than in pure stand was highly significant at the two higher plant densities. For Pride 116, the number of proportions yielding more than in pure stand was highly significant at the highest plant density.Key words: Corn, grain yield, mixtures of different proportions, high plant densities, Zea mays

The results revealed that parents namely, TSK-10, TSK-27, New Blue-II, Kurara and TSK-109 were found highly genetic diverse for days to 50% tasseling, days to 50% silking, days to 755 dry husk. The parents namely, TSK-109, Kurara, New Blue-II and TSK-10 were found highly genetic diverse for plant height (cm), cob height, number of cobs per plant and number of grains per cob. The parents namely, Kurara, TSK-109, TSK-10, New Blue-II and TSK-27 were found highly genetic diverse for shelling percentage, grain yield per plant, grain yield per cob and 100-grain weight.

The investigation evaluated the effect of fertilizers potásicos with fosfitos on the yield of grain of hard corn (Zea mays L.), in the Property "Santiago", located in the Km 26 way Babahoyo-San Juan, county of Los Ríos. A rehearsal settled down in the hybrid corn DK-7088, measuring the answer from the corn to the application of fertilizers potasic and fhosphite, to determine the dose with more effect on the production. 19 treatments were proven with Chloride of potassium, Sulfate of potassium and Nitrate of potassium, with fhosphite of Calcium, Magnesium and Potassium, more a witness without applications. The used experimental design was complete Blocks at random in three repetitions, the evaluated variables were subjected to the variancia analysis, and the test was applied from Tukey to 95% of probability. The evaluated parameters were: plant height, days to flowering, longitude and ear diameter and yield for hectare. Found increases in grain yield with three treatments, highlighting the treatment with the application of muriate of potash in conjunction with Calcium phosphide (9451,65 kg ha1 ). The results indicate the possibility of increases of more than 49% in relation to the witness (6339 kg ha1 ) where there was applied the treatments.
