Effect of biochar particle size and biofertilizers on lentil (Lense culinarous M.) yield and available fractions of soil nutrients
Suitable management techniques are required to improve soil nutrient availability and crop yield. This study evaluated biochar particle sizes (<2 mm, 2-5 mm and 5-10 mm) in combination with rhizobia inocula (Biozote-N (Rhizobium leguminosarum (BZ)) and Rhizogold (a mixture of Rhizobium legumino...

| Summary: | Suitable management techniques are required to improve soil nutrient availability and crop yield. This study
evaluated biochar particle sizes (<2 mm, 2-5 mm and 5-10 mm) in combination with rhizobia inocula (Biozote-N (Rhizobium
leguminosarum (BZ)) and Rhizogold (a mixture of Rhizobium leguminosarum with other plant growth promoting bacteria
(RG)) for enhancing lentils yield and nutrients availability in a low fertility alfisol using randomized complete block split plot
design during Winter 2015-16. Biochar with lowest particle size (< 2 mm) showed the maximum 13, 17, 6 and 17% increase
in bundle weight, straw yield, grain yield and thousand grain weight, respectively, and 27, 43 and 18% increase in soil
mineral nitrogen (N), phosphorus (P) and potassium (K) status, respectively, compared to no Biochar plots. The Bizote-N
inoculation improved the grain yield by 4%. Combination of Bizote-N and the biochar smallest particle size (< 2 mm)
resulted in more mineral N content. The extractable K was highest at < 2 mm particle size and no biofertilizer treatment
followed by Bizote-N inoculation. It was concluded that the Biozote-N performance was consistent with the lowest biochar
particle size (< 2 mm) for enhanced lentil yield and soil fertility. |
