- Abstract
Sweet corn (Zea mays L. saccharata Sturt.) is a horticultural commodity that has a fairly high nutritional content such as fiber, calories, vitamins, minerals. Based on data from the Central Bureau of Statistics (2018) the average sweet corn production in East Java in 2017 was 5.04 tons/ha, while the potential yield of sweet corn could reach 25 tons/ha. So it is necessary to make efforts to increase the production of sweet corn. The aim of this study was to obtain the optimum dose of inorganic N fertilizer and combination of organic N doses for the growth and yield of sweet corn (Zea mays L. saccharata Sturt.).The study was conducted using a factorial Randomized Block Design (RBD) consisting of 2 factors. The first factor is the dose of inorganic N fertilizer consisting of 3 levels: F1 = 100% inorganic N fertilizer; F2 = 75 % inorganic N fertilizer; F3 = 50% inorganic N fertilizer. The second factor is inorganic N sources consisting of 4 levels: P1 = Manure 10 t ha-1; P2 = Manure 20 t ha-1; P3 = Manure 10 t ha-1 + PGPR P4 = Manure 20 t ha-1 + PGPR. The results showed that there was no interaction between the doses of inorganic N fertilizer and the combined doses of organic N. Separately, the dose of inorganic N fertilizer had a significant effect on the variables of plant height, stem diameter, leaf area, chlorophyll content, cob weight, and sweetness level. The application of inorganic N fertilizer of 75% resulted in a higher weight of sweet corn cobs per hectare of 17.52 tonnes ha-1. The combination of organic N doses had a significant effect on the variables of plant height, stem diameter, leaf area, chlorophyll content, cob weight, and sweetness level. Application of 10 tons ha-1 of manure + 10 ml-1 PGPR resulted in a higher weight of sweet corn cobs per hectare of 17.16 tons ha-1. [ABSTRACT FROM AUTHOR]
