Growth and yield of summer groundnut (Arachis hypogaea L.) under the influence of biochar and organics

Abstract

A field experiment was carried out during summer season of 2019-20 on organic plot having black calcareous clayey soil at Junagadh (Gujarat) to study the effect of biochar on growth and yield of summer groundnut (Arachis hypogaea L.). The results indicated that the highest values of growth attributes viz., plant height, number of branches per plant, days to 50% flowering, number of root nodules and dry weight of root nodules and SPAD meter reading and yield attributes viz., peg to pod ratio, number of mature pods per plant, 100-pod weight and 100-kernel weight, pod weight per plant and shelling percentage along with the highest pod yield (2201 kg/ha) and haulm yield (4219 kg/ha) were recorded with application of enriched biochar 0.25 t/ha + vermicompost 1 t/ha, followed by microbial enriched biochar 0.25 t/ha + FYM 1.25 t/ha + vermicompost 0.5 t/ha.
