Effects of Liquid Nano-Carbon Bio-Fertilizer on the Growth of Spinach

In order to compare the effects of liquid biological nano-carbon fertilizer, humic acid and urea on the growth of Spinach, a field plot experiment was conducted to study the effects of five different treatments on root length, yield and quality of annual Spinach. Fertilizer had a significant effect on root length of annual Spinach. The order of root length was T3 > T5 > T4 > T2 > T1. The growth rates of roots were 21.69%, 18.94%, 14.26%, 3.76% and 0.0%, respectively. Fertilizer significantly increased the yield of annual Spinach. The order of yield increase was T5 > T3 > T4 > T2 > T1. The yields were increased by 16.66%, 14.71%, 10.55%, 6.44% and 0.0%, respectively. Potato liquid nano-carbon bio-fertilizer has a significant effect on maintaining the growth and increasing yield of Spinach.
