Abstract
A field experiment was conducted during 2011–12 and 2012–13 on sandy loam soil at Uttar Chandamari village (22°57 ’N, 88° 20 ’E), Kalyani, District Nadia, West Bengal, to study the effect of seaweed (Kappaphycus and Gracilaria) saps on crop growth, yield and nutrient uptake and monetary advantages in rice (Oryza sativa L.)-potato (Solanum tubersoum L.)-blackgram [Vigna mungo (L.) Hepper] sequence. Pooled results indicated that foliar application of seaweed extracts at different concentrations (2.5, 5.0, 10.0 and 15.0% V/V) significantly enhanced the growth, yield and nutrient uptake of all the crops. Application of 15% Kappaphycus sap with 75% recommended dose of fertilizer (RDF) resulted in the highest productivity in terms of rice-equivalent yield (REY) with annual net monetary returns of 231, 686/ha and benefit: cost ratio of 2.61. The highest N, P, K uptake in all the crops was also observed in the same combination.
