Abstract:
Present investigation was conducted during 2010-11 and 2011-12 at Gandhi Krishi Vigyana Kendra, University of Agricultural Sciences, Bengaluru to study the effect of Bio-Digested Liquid Manures on Soil Fertility, Productivity and Quality of Onion (Allium cepa L.). Application of enriched biodigested liquid organic manure (EBDLM) at 25 kg N equivalent ha-1 + 3 sprays of panchagavya (PG) at 3 % produced significantly higher bulb yield (37.78 t ha-1) and was found on par with that of EBDLM @ 125 kg N equi.ha-1 + VW spray @ 3 % (36.01 t ha-1) and EBDLM @ 125 kg N equi.ha-1 (34.96 t ha-1). The treatment receiving recommended FYM 30 t + 125:50:75 kg N:P2O5:K2O ha-1 recorded the lowest bulb yield (25.59 t ha-1 ) as compared to other treatments. The onion quality parameters like TSS, reducing, non-reducing and total sugar, protein, ascorbic and pyruvic acid content of onion bulb (16.93, 3.66, 8.66, 12.32 1.36 %, 25.27 mg 100-1 g & 12.82 µ moles g-1, respectively) were significantly superior with EBDLM @ 125 kg N equi.ha-1 + PG spray @ 3 %. Further with respect to soil fertility significantly higher available nitrogen, phosphorus, potassium and sulphur (355.1, 78.3, 190.8 & 36.3 kg ha-1, respectively) was noticed with T6 as compared to other treatments and it was on par with T5 (342.6, 75.3, 197.1 & 32.7 kg ha-1, respectively) and T4 (324.9, 72.1, 185.2 & 32.2 kg ha-1, respectively).
