Effect of Sea Weeds Saps on Growth Yield and Economics of Sesamum

Abstract

A field experiment was conducted at Agricultural Research Station, Yelamanchili with nine treatments comprised of T1- 2.5 % K Sap + RDF, T2- 5 % K Sap + RDF, T3- 10 % K Sap + RDF, T4- 15 % K Sap + RDF, T5- 2.5 % G Sap + RDF, T6- 5 % G Sap + RDF, T7- 10 % G Sap + RDF, T8- 15 % G Sap + RDF, T9- Control only RDF (With water spray) to identify suitable sea weed sap and concentration for obtaining higher yields in sesamum. The experimental results on growth parameters like Plant height, number of branches, LAI and crop growth rate revealed that significant improvement in these parameters was observed with spraying G Sap and K-Sap at 2.5 to 15 % concentrations. The maximum values of growth parameters was recorded with 10% G Sap spraying followed by K-Sap at 10% Conc. Followed by and G-Sap and K-Sap at 5% Concentration. The number of capsules higher with 5 % K Sap + RDF followed by 10 % G Sap + RDF and 5 % G Sap + RDF. The highest sesamum yield was recorded with 10% G-sap (325 kg/ha) followed by 10% K-Sap (314 Kg/ha), which were significantly superior over rest of all other treatments. Highest gross returns, net returns and BC ratio was recorded with 10 % G Sap and 10%K-Sap. The study can be concluded as along with recommended dose of fertilizers spraying G Sap or K-Sap of sea weeds at 10 concentrations is required for realizing higher seed yield and returns in sesamum.
