Abstract

Sweet corn is one of the crops that has a fairly large role in provide the nutritional needs of the people. One of the effort that can  be do to improve the growth and production of sweet corn is fertilization. Bioslurry can be used as an organic fertilizer to plants. Application of bioslurry is neeed to combine with an anorganic fertilizer that rich of elements such as  N P K  like Urea, TSP, KCl. This study aimed to know the effect of bioslurry and Urea, TSP, KClinteraction  on the growth and production of sweet corn (Zea mays saccharata Sturt.) and get the best gift. This research was experimently using a Randomized Block Design (RBD), which are arranged in factorial, which consists of 2 factors and 3 replications. Parameters measured were plant height (cm), number of leaves (pieces), male flowers appear time, female flowers appear time (HST), weigth of cob with husk per plot (gram), weigth of cob without husk per plot (gram ), cob length (cm) and cob diameter (cm). The results showing the interaction of fertilizer application bioslurry and Urea, TSP, KCl fertilizer were not significant on all parameters observation. Bioslurry application significantly affected the number of  leaves and female flowers appear time, while the application of  Urea, TSP, KCl significantly affected plant height. Application 2.25 liter bioslurry and Urea 175 kg / ha of + TSP 125 kg / ha + KCl 75 kg / ha gives the best results. Keywords: sweet corn, bioslurry, Urea, TSP, KCl fertilizer.

The study was conducted in the experimental station of Agriculture Faculty of Riau University by using a randomized completely block design with 2 factors and3 replications. The first factor was water hyacinth compost consisted of 5 levels namely: 0 t.ha-1, 5 t.ha-1, 10 t.ha-1, 15 t.ha-1and20 t.ha-1water hyacinth compost. Meanwhile the second factor was plant spacing which consisted of 2 levels namely: (40 x 15) cm and (40 x 20) cm. The result of this study indicated that water hyacinth composting give effected on plant height, number of branches, number of pods per plant, number of filled pods per plant, seed weight per plant, seed weight per plot, seed weight per m2andweight of 100 seeds, while plant spacing give effected on seed weight per plot andseed weight per m2.

Abstract

This study aims to determine the effect of the interaction of corn waste compost and phosphorus fertilizer, corn waste compost, phosphorus fertilizer application, and get a better dose of corn waste compost and phosphorus fertilizer on the growth and production of sweet corn plants. This research was carried out experimentally in the field using a factorial randomized block design (RBD), namely corn waste compost (0, 2.5, 5, and 7.5 tons.ha-1) and phosphorus fertilizer (200, 300 and 400 kg.ha-1). The parameters observed were plant height, stem diameter, number of leaves, time appears the female flowers, age of harvest, weight per cob with cornhusk, production per ha, weight per cob without cornhusk, number of rows of seeds per cob, and number seeds per row. The data obtained were statistically analyzed by analysis of variance and continued with Duncan's New Multiple Range Test (DNMRT) at the level of 5%. The results showed that there was an interaction of corn waste compost and phosphorus fertilizer in the production parameters per ha of sweet corn plants. Corn waste compost can increase plant height, stem diameter, weight per cob with cornhusk, and production per ha. The best gave is in the treatment of 7.5 tons.ha-1. The application of phosphorus fertilizer can increase plant height, stem diameter, time appears the female flowers, age of harvest, weight per cob with cornhusk, and production per ha. The best gave is in the treatment of 400 kg.ha-1. The application of 7.5 tons.ha-1 corn waste compost with 400 kg.ha-1 phosphorus fertilizer showed better results in almost all parameters, except for the number of leaves,number of rows of seeds per cob, and number seeds per row. Keywords: sweet corn, corn waste compost and phosphorus fertilizer
