The Effect of Different Organic Sources on Growth and Yield of Sweet Potato

Abstract

The sweetpotato ( Ipomoeabatatas L.) or Irish potato is originated in tropical South America which was cultivated for its tuber production throughout the India occupying an area of 1,34,880 ha with production of 16 38,840 MT. Whereas in Andhra Pradesh, sweet potato is cultivated in an area of 530 ha with a production of 10,910 MT (NHB, 2018). In this article we have focused on the effect of different organic sources supplied from organic manures, vermicompost, Arka microbial consortium i.e., Nitrogen, Phosphorus and Potassium on growth and yield of sweet potato was expressed in kg/ha by performing standard methodology. Among organic manures application of vermicompost @ 8.3 t/ha recorded maximum uptake of nutrients with 37.47 kg/ha 8.31 kg/ha and 27.16 kg/ha of NPK respectively. Thereby indicating the vital role of these sources in the transformation reaction of these three nutrients in the soil.
