Biological inputs through seed and foliar nutrition are ideal for improving crop yield and are environmentally safe. It is also gaining more attention in recent past years because of its biosafety nature. Hence, an experiment was conducted to study the influence of herbal extracts (sweet basil and Lantana) and DAP singly and in combination on the biochemical parameters of green gram (Vigna radiata L.).There were six treatments T1(DAP – 2%),T2(Sweet basil leaf extract (10%)),T3(Lantana leaf extract (10%)), T4(DAP 2% and sweet basil leaf extract (10%)),T5(DAP 2% and Lantana leaf extract (10%)) and T6(DAP 2% and Lantana leaf extract (10%) and sweet basil leaf extract (10%)) with control red soil. The biochemical parameters observed indicated that chlorophyll ‘a’ was maximum in T6 plants on 45 DAS T1 plants on 60 DAS and T4 plants on 75 DAS. Chlorophyll ‘b’ was more in T5 on 45 DAS and on 60 and 75 DAS it was more in T2 plants. Total chlorophyll was more in T2 on 45 DAS, and T5 showed more contents on 60 and 75 DAS. Protein content was more in T6 plants on 45th and 60th DAS and T4 plants showed maximum protein content on 75 DAS. Total carbohydrates content was maximum in T3 on 45 and 75 DAS and on 60 DAS it was in T6 plants. Highest content of ascorbic acid was observed in T5 on 45 and 60 DAS and in T6 on 75 DAS. From the investigation it is concluded that the foliar application of herbal extracts of Lantana and sweet basil could be an ideal and suitable green manure for green gram.
