Abstract:

A study was conducted to determine the influence of seaweed saps [Gracilaria edulis (G sap) and Kappaphycus alvarezii (K sap) on germination, growth and Seedling Vigor Index (SVI) under laboratory conditions followed by a field experiment to examine its foliar application on growth and yield of hybrid maize. Bioassay results revealed that soaking maize seeds in various concentrations from 5% to 15% either with G or K sap significantly increased the germination percentage (96.67%) at 5% level. However, higher shoot length (7.66 and 8.67cm), SVI (3410 and 3661) at 7th and 15th days and dry weight of seedlings (0.92g) were recorded in 15% K sap soaked seeds. Field experiment involved in soaking of maize seeds in seaweed saps followed by foliar application at different intervals. Results revealed that application of seaweed sap for maize crop with G or K saps at varied concentration, significantly increased cob length (17.63cm), number of grains (568.33g) and grain weight cob-1 (56.22g), test weight (33.67g), grain and stover yield (4377.10 and 5764.31 kg ha-1 respectively), were recorded when seeds were treated with 15%G sap along with 10%G sap spray at 20, 40 and 70 days after sowing. This study clearly indicated the benefit of seaweed sap application to maize crop particularly, 15%G sap seed soaking followed by G sap spray in increasing the maize yield.
