The Effort to Increase Waxy Corn Production as the Main Ingredient of Corn Rice through the Application of Phosphate Solvent Extraction and Phosphate Fertilizer

This research aims to find out the effect and functional relationship of coconut ash organic fertilizer application on the increasing yield and quality of waxy corn. There are seven treatments of coconut ash fertilizer dosage, i.e. 0.00 ton/ha, 0.75 ton/ha, 1.50 ton/ha, 2.25 ton/ha, 3.00 ton/ha, 3.75 ton/ha, and 4.50 ton/ha. Data is analyzed using one way anova, t test for 2 independent samples, and simple linear regression analysis. Fertilizer dosage has significant effect on ear height position from soil surface, the number of seed row on ear, ear weight with and without dried husk, waxy corn production with and without dried husk, and starch, amilose, and amilopectin contents. The highest average of ear height position and the amount of seed row is obtained at dosage 0.75 ton/ha. Dosage 2.25 ton/ha gives highest average for ear weight with and without dried husk, while dosage 3.75 ton/ha results highest average for variables of waxy corn production with and without dried husk. Dosage 3.75 ton/ha also gives highest average for starch and amilopectin contents and lowest average for amilose content. One way relationship happens between fertilizer dosage with ear height position, the amount of seed row, ear weight, waxy corn production, starch and amilopectin contents.

ABSTRACT Melon producers, in Chapada do Apodi, Rio Grande do Norte State, Brazil, located between the states of Ceará and Rio Grande do Norte, have cultivated corn in succession to the melon crop. However, this crop rotation is not yet evaluated on the extent to which the residual effect of nitrogen and phosphate fertilization carried out in melon can supply partially or completely the corn demands of nitrogen and phosphorus. This work aimed to evaluate the effect of nitrogen (N) and phosphorus (P) in the production of corn in succession to the cultivation of melon (Cucumis melo) irrigated in an Alkaline Inceptisol of Chapada do Apodi. Ten treatments from the combinations between five N rates (0; 45; 90; 160 and 220 kg/ha) and four levels of P2O5 (0; 40; 80; and 120 kg/ha) were compared. The experimental design was a randomized block with four replications. The corn cultivar was the hybrid AG 1051 and the characteristics evaluated were number and total weight of ears, number and weight of marketable unhusked ears and concentrations of N and P in plant and P in the soil. This study also estimated critical levels of N and P in the plant and P in the soil. Producing green corn in succession to melon is viable, in this experiment conditions, without application of nitrogen and phosphorus to the soil. However, for maximum corn productivity, application of 90 kg/ha N combined with 40 kg/ha P2O5 is recommended. The average critical level of N and P in the plant for corn production was 32.29 and 4.31 g/kg, respectively. This value for P in the soil was 20.7 mg/dm3.

Rice bran oil is the oil extracted from rice bran. This is edible oil that is very good for health so that potential as a functional food, and can be develop the agroindustry. Solvent extraction process is done using n-heksane and ethanol. The purpose of this study was to determine the best ratio of rice bran with n-heksane and ethanol to obtain the highest percentage of the oil. The main ingredient of this study is rice bran, n-heksane and ethanol. The extraction process is done at a temperature of 55° C, 200 rpm for 5 hours. The results showed that the best ratio of bran and n-heksan to produce the ultimate percentage of oil is 1: 7 that is equal to 7,53%, as well as the best ratio of bran and ethanol to produce the ultimate percentage of oil is 1: 6 that is equal to 8,49%.
