Growth Response of Maize Plant Due to Biochar Rice and Fertilizer of Soil in Kwala Bekala, North of Sumatera

Abstract

Inceptisol of Soil in Kwala Bekala Deli Serdang is the dominant agricultural land cultivated corn crop. However, the results obtained currently do not meet the desired target by farmers. A greenhouse study has been conducted to evaluate the response of corn plant growth through the application of rice husk biochar and manure on Ultisol of Soil in Kwala Bekala, Deli Serdang, North of Sumatera. This research was conducted using Randomized Block Design of Factor (RBDF) with 2 treatments. Treatment I used by biochar rice husk (B) with 4 levels ie B0 (0 g / polybag), B1 (25 g/polybag), B2 (50 g/polybag) and B3 (75 g/polybag). The second treatment is cow manure (S) with 4 levels i.e. S0 (0 g/polybag), S1 (25 g / polybag), S2 (50 g/polybag) and S3 (75 g/polybag). Each combination of treatments. repeated 3 times so that there are 48 experimental units. The results showed that application of rice husk biochar of 50 g / polybag able to increase P uptake of plants by 9.96 mg / maize plant and increase plant height up to 176.17 cm. Application of cow manure of fertilizer of cow as much as 50 g/polybag can increase uptake of P, plant height, root dry weight and corn plant respectively 6.09 mg/plant, 185,78 cm, 17,06 g and 152,58 g. Meanwhile, rice husk (50 g/polybag) intrusion and cow manure (50 g/polybag) were also able to increase P uptake of corn plant up to 5.39 mg/plant.
