Production of Sweet Corn on Sand Pit Soil Using Phosphate Solubizing Bacteria and Weed Bokhasi

Sand pit soil which poor physical, chemical, and biology soil properties can be used for planting media of horticulture crops through adding beneficial microbe and organic matter. The aim of the research was to know the effect of Phosphate Solubizing Bacteria and Bokhasi on growth and yield Sweet Corn at sand pit soil. A field trial at 750 m above sea level had been carried out from Juni to October 2018 using randomized block design two factors with factorial pattern and three replications. The first factor was Phosphate Solubizing Bacteria (0 ml, 20 ml polybag-1, 25 ml polybag-1, 30 ml polybag-1, while the second factor was bokhasi type (Tithonia diversifolia, Imperata cylindrica, and Eichornia crassipes). The results showed that Phosphate Solubizing Bacteria and bokhasi had interaction effect on harvest index, Phosphate Solubizing Bacteria and bokhasi had main effect on crop height , dry and wet corn cob with out corn straw, and bokhasi had main effect shoot root rasio. So application of weed bokhasi of T. Diversifolia and I. cylindrica can be used to promote corn crop growth and crop yield. While application PSB dosage 25 ml polybag-1 increase growth and yield of the corn crop
