Abstract
The present study “Effect of different SSP formulations on growth, yield and quality parameters” was conducted. Different formulations of SSP were taken as treatment combinations. Trial was laid with six treatments and was replicated four times following a randomized block design. Treatments taken were namely SSP-C, SSP-L, SSP-1, SSP-2, SSP-3 and SSP-4. Their effects on potato were studied in context to growth, yield and quality parameters. Observations were taken on intervals at various growth stages. It was found that treatments with higher phosphorus releasing effeciency showed highest plant height, shoot emergence %, leaf area, chlorophyll content, stem diameter, yield, marketable yield, weight of tubers. Quality parameters like TSS, starch content, protein content, fiber content etc did not show much of variation. The process of manufacturing SSP is generally inorganic based. Organic acidulation of SSP with various acids increased its relative effeciency and showed better results in accordance to other sources. In control plot plant stand was good but due to lack of nutrition growth was stunted and yield was reduced. It can be concluded that potato variety grown with proper management practices and organic acidulated source of SSP gives better results in growth, yield and quality aspects. All the data were analyzed and overall it is found that treatment SSP-4 gave better efficacy than other group of SSP fertilizer.
