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.

Organic amendments role in reducing drought stress in Alcea Rosea L.

“…Chekanaia et al (2018) showed that the appli cation of nitrogen (ammonium phosphate) and phos phorus (superphosphate) in beans doubled the dry weight and plant yield in both treatments compared to the control. Lubis et al (2021) stated that dry weight of rice and plant height that received ele ments increased under manure medium. Potassium reduces the negative effect of drought stress on leaf area index and plantʼs dry weight by increasing the ability of photosynthesis, the rate of CO 2 stabilizing with interference in osmosis, the activity of the enzyme Rubisco, and improving the synthesis and transport of dry matter (Wang et al, 2013).…”

Biochar and compost amendment to enhance sweet corn growth

“…Thus, nutrients on the soil surface are available for plant uptake (Zwieten, 2012). Besides, Lubis et al (2021) found that treatment with 50 g/polybag of biochar increased the corn plant height up to 176.17 cm. Adding biochar may retain more water and alter the pore space of the soil, allowing roots to grow freely and absorb many nutrients.…”
