Abstract:
The experiment entitled “Impact of Sulphur and Zinc fertilization on the growth and yield of Blackgram (Vigna mungo L.) under the rainfed condition” was laid down factorial randomized block design with tree replication and sixteen treatments. The plant spacing was kept 40X10sqcm in T9 variety. In relation to growth parameters the best treatment interaction was 20kg. S plus 15kg Zn/ha which recorded the maximum height i.e., 11.80cm. at 20 days, 29.86 cm at 40 days and 68.73cm at 60 days stage. This treatment interaction was found significantly superior to most of the remaining having S level only up to 10kg/ha with all the Zinc level. However, the second best interaction was 30kg S plus 10kg. Zn/ ha. In contrast to this, the significant lowest plant height was recorded in case of without S and Zn application (absolute control). Among the yield parameters, the best treatment combination appeared to be S₂₀Zn₁₅ producing 10.90q/ha grain. This was followed by S₂₀Zn₁₀ and S₃₀Zn₁₀ interactions producing equal grain (10.48 to 10.35/ha) on the other hand the lowest yield only 7.30q/ha ware recorded in case of absolute control (S₀Zn₀).
