Abstract

Rice – Blackgram was the major adopted cropping system of Tamil Nadu. Increasing the productivity of blackgram by reducing the usage inorganic fertilizer, in view of improving soil fertility without affecting the productivity of the crop with a proper residue management practice was the main objective of this research. The field experiment was conducted in blackgram Vamban (VBN 8) during January – June, 2020, to study the influence of crop residue, inorganic fertilizers and vermicompost on the growth, yield and yield attributes of blackgram under rice - blackgram cropping system. Blackgram with and without incorporating preceding rice crop residue were taken as vertical factors V1 – blackgram with incorporation of rice residue, V2 – blackgram without incorporation. Different fertilizer recommended doses in combination with vermicompost as an integrated approach were taken as horizontal factors H1- 100 per cent recommended dose of fertilizer alone, H2- 75 per cent recommended do

Keywords

Blackgram, fertilizer, rice residue, vermicompost, yield.

Conclusion

The study concluded that without incorporation of rice residue and the application of 100 per cent recommended dose of fertilizer alone (V2H1) recorded higher growth and yield of blackgram Vamban (VBN 8). This was found on par with no rice residue incorporation and 75 per cent recommended dose of fertilizer plus 25 per cent application of vermicompost (V2H3) and blackgram without rice residue incorporation with 75 per cent recommended dose of fertilizer alone (V2H2). Incorporation of rice residue with the application of 100 per cent recommended dose of fertilizer alone (V1H1) was also found on par with the same trend. And least of all the attributes (plant height, leaf area index, dry matter production, number of pods per plant, number of seeds per pod, grain and haulm yield) were recorded in blackgram with rice residue incorporation treatment along with 50 per cent recommended dose of fertilizer alone (V1H4).
