Performance of Sulphur and Boron on Growth and Yield of Black Gram (Vigna mungo L.)

Background: A field experiment entitled “Performance of Sulphur and boron on growth and yield of Urd bean (Vigna mungo L.) was carried out during Zaid season 2023 on the farms of Lovely Professional University Phagwara, Punjab. Methods: The experiment was carried out in Randomized Block design having ten treatments which are replicated three times. The treatments include T1: Control, T2: RDF + 0.1% Boron, T3: RDF + 0.2% Boron, T4: RDF + 0.3% Boron., T5: RDF + 17.5 kg ha-1 Sulphur, T6: RDF + 35 kg ha-1 Sulphur, T7: RDF + 52.5 kg ha-1 Sulphur, T8: RDF + 0.1% Boron + 17.5 kg ha-1 Sulphur, T9: RDF + 0.2% Boron + 35 kg ha-1 Sulphur, T10: RDF + 0.3% Boron + 52.5 kg ha-1 Sulphur. Result: The results of study indicated that the agronomic characteristics of Black gram (Vigna mungo L.) crop were significantly maximum in plots treated with 0.2% Boron + 35 kg ha-1 Sulphur along with RDF and gave maximum growth and yield. The seed yield of 10.95 q ha-1, stover yield of 24.03 q ha-1 and 31.30% harvest index with net return of Rs. 51668.67 ha-1 and B:C ratio of 1.62. Thus, it is suggested that the 0.2% Boron + 35 kg ha-1 Sulphur along with recommended dose of fertilizer (12: 25 kg NP ha-1) would be useful in achieving maximum growth and yield of black gram under similar agro-climatic conditions and soil properties.
