e1“A field experiment was conducted in red sandy loamsoils of North Coastal Andhra Pradesh to study the effect of biochar on soil physical and hydrological properties, and on growth and yield of rabi groundnut (variety K-6) during 2018-19”
e7“Groundnut crop growth in the form of leaf area index at pod development stage was highest (3.16) in T5 (biochar 6 t /ha + 100% RDF)”
e6“both T5 & T4 were significantly higher than T6, T7, T8, T2 and T1”

Other claims from this paper (14)
- Intervention effect Biochar at 6 t/ha (T5 and T8) significantly lowered soil bulk density at sowing compared with control and 100% RDF.
- Intervention effect Biochar at 6 t/ha (T5 and T8) significantly raised total soil porosity at sowing compared with control and 100% RDF.
- Observation The control (T1) had the highest soil bulk density, 1.58 Mg/m3, at the sowing stage.
- Observation The control (T1) had the lowest total soil porosity, 40.38%.
- Intervention effect Biochar at 6 t/ha (T5 and T8) significantly increased soil maximum water holding capacity compared with control and 100% RDF.
- Intervention effect Increasing the biochar rate from control up to 6 t/ha increased soil water retention (MWHC).
- Intervention effect Biochar addition gave a slight, non-significant decrease in final infiltration rate and saturated hydraulic conductivity.
- Observation Soil bulk density, soil penetration resistance and soil temperature increased in groundnut fields from sowing to harvesting.
- Observation Percent pore space of the soil decreased from sowing to harvesting of groundnut.
- Intervention effect Biochar at 6 t/ha + 100% RDF gave the highest dry matter accumulation at peg penetration (2950.90 kg/ha).
- Intervention effect Biochar at 6 t/ha + 100% RDF gave the highest dry matter accumulation at pod development (6427.54 kg/ha).
- Intervention effect Biochar at 6 t/ha + 100% RDF gave the highest groundnut pod yield, 4020 kg/ha.
- Intervention effect Biochar at 4 t/ha + 100% RDF or 6 t/ha + 75% RDF increased nutrient availability in the soil.
- Intervention effect Biochar at 4 t/ha + 100% RDF or 6 t/ha + 75% RDF gave a better soil physical environment.
