Effect of seaweed saps on growth, yield, nutrient uptake and economic improvement of maize (sweet corn)

Journal Title: Journal of Applied and Natural Science - Year 2015, Vol 7, Issue 2

Abstract

A field experiment was conducted during the rabi season of 2012-13 at Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) to study the effects of seaweed saps on growth, yield, nutrient uptake and economic of maize (sweet corn) in Matasi soil of Chhattisgarh. The foliar spray of two different species (namely Kappaphycus and Gracilaria) was applied thrice at different interval of crop with different concentrations (0, 2.5, 5.0, 7.5, 10.0 and 15% v/v) of seaweed extracts. Foliar applications of seaweed extract significantly enhanced the growth, yield, nutrient uptake and B:C ratio parameters. The green cob yield (189.97 q ha-1) and fodder yield (345.19 q ha-1) were recorded highest under treatment (T8) 15% G Sap + recommended dose of fertilizer (RDF) which was significant similar with treatment 15% K Sap + RDF (185.24 q ha-1) in case of green cob yield. The highest N, P and K uptake by green cob and fodder were observed under 15% G Sap + RDF (T8). Treatment 15% G Sap + RDF (T8), recorded maximum gross return (Rs. 2,07,230 ha-1), net return (Rs. 1,38,756 ha-1) and B:C ratio (2.0), which was followed by treatment 15% K Sap + RDF (T4) with net return (Rs. 1,33,199 ha-1) and B:C ratio (1.95). Treatment 15% G Sap + RDF (T8) gave Rs. 45,996 ha-1 more as compared to Water spray + RDF (T9).
