Abstract

Phosphate solubilizing fungi (PSF) from paddy soil can used as biofertilizer to increase P availability.Aimed this experime nt was to increase P availability, growth and paddy rice production. The randomly complete block design used that consist two factors, eg. Dosage of PSF (A) and anorganic P fertilizer (F). Factor dosage of PSF (A) with four levels: without PSF; 2 kg PSF/plot; 4 kg PSF/plot and 6 kg PSF/plot. Factor anorganic P fertilizer with three levels: without anorganic P fertilizer; 50% anorganic P fertilizer and 100% anorganic P fertilizer. Experiment result showed that application of PSF increased P availaibility, growth and plant production more high than without application of PSF. Application of anorganic P fertilizer increased P availability, growth and plant production more high than without application of anorganic P fertilizer. Interaction between  application of PSF with anorganic P fertilizer (4 kg PSF/plot + 100%  anorganic P fertilizer)  increased P availibility, growth and plant production more high  than without  application of  PSF and anorganic P fertilizer (control).

Abstract

The research was conducted to evaluate the performance of tomatoes varieties on growth, yield and quality through the application of partial rootzone drying. The study was conducted in green house at the Faculty of Agriculture Universitas Islam Sumatera Utara (UISU) Medan in May 2014 until September 2014. The planting media used were straw compost mixed with top soil enriched withUrea, SP ─ 36 and KCL fertilizer filled into polybeg up to 10 kg in weight. Observation variables are: the growing, yield  and quality of tomato
