Description An incubation experiment was conducted under green house
conditions at UAS, GKVK, Bangalore and a field experiment conducted at
farmer?s field, Somsettyhalli, Doddballapur Taluk, Bangalore Rural
district to study the effect of human urine enriched biochar on soil
properties, growth and yield of French bean crop during summer 2013.
The incubation experiment was conducted for preparation of nutrient
rich biochar using human urine at different ratios (1:0.75, 1:1, 1:1.25,
1:1.5, 1:1.75 and 1:2). The increase in nutrient composition of coconut
shell biochar was observed due to addition of human urine by preventing
the loss of ammonia during incubation with H2SO4 treatment. The field
experiment was conducted with nine treatments and three replications.
The design was RCBD. Application of enriched biochar 1(1:2) to supply
50% recommended N and 50% N through fertilizer and 100% P and K
through fertilizer (T4) has resulted in better plant growth and nutrient
uptake by crop and also the vegetable yield of French bean. Significant
differences in Physical, chemical and biological properties of soil were
observed except bulk density and pH of the soil. Among chemical
properties of soil, the Zn, Cu and B content did not differ significantly
between the treatments. The findings of this study clearly showed that
application of enriched biochar using human urine has resulted in better
crop growth and yield of French bean, reflecting and confirming the
improved nutrient availability in soil.
