Effect Of Combination Of Organic Fertilizer And Inorganic Fertilizer On The Growth And Production Of Hybrid Corn Of Variety JH37

The longer the nutrients in the soil will decrease. Lack of nutrients needed by plants can be overcome by fertilization. Fertilizers used can be in the form of organic fertilizers and inorganic/chemical fertilizers (NPK). This study aims to determine the effect of a combination of organic and inorganic fertilizers on the growth and production of hybrid corn JH37. This study used a randomized block design (RBD) consisting of 12 combinations of organic and inorganic fertilizers. The treatment was repeated 3 times. The treatment factors that were tried were as follows: A0B0 (No Manure, No NPK Fertilizer), A0B1 (No Manure+150 kg/ha NPK), A0B2 (No Manure+200 kg/ha NPK), A0B3 (No Manure+250 kg/ha NPK), A1B0 (10 tonnes/ha of manure + without NPK fertilizer), A1B1 (10 tonnes/ha of manure + 150 kg/ha of NPK), A1B2 (10 tonnes/ha of manure +200 kg/ha of NPK), A1B3 (10 tonnes /ha Manure +250 kg/ha NPK), A2B0 (20 tons/ha Manure + Without NPK Fertilizer), A2B1 (20 tons/ha Manure +150 kg/ha NPK), A2B2 (20 tons/ha Manure +200 kg/ha NPK), A2B3 (20 tonnes/ha of manure +250 kg/ha NPK). The variables observed were: plant growth and production. Plant growth includes plant height measured every 2 weeks starting at 14 days old until the final vegetative phase, leaf length, leaf width, and stem diameter (measured in the late vegetative phase). Production (cob diameter, fresh cob weight, cob dry weight, dry shell weight, and production per hectare were measured after harvest). Data were analyzed using analysis of variance. If the effect of the treatment is obtained, it is continued with the Least Significant Difference Test (LSD) at the 5% level. The results showed that the combination of organic and inorganic fertilizers increased the growth and production of hybrid maize Var. JH37. A dosage of 20 tons/ha of organic fertilizer + 200 kg/ha of the best inorganic fertilizer increases the growth and production of JH37 hybrid corn. Production of hybrid corn var. The highest JH37 was in the A2B3 combination (20 tonnes/ha of manure + 250 ...
