Influence of Various Organic Sources on Soil Nutrient Status and Nutrient Uptake of Ragi under Guni Method

A field experiment was conducted during the kharif-2019 at the farmers field of Mylandahalli in Chikkaballapura distict of Karnataka, to study the effect of organic nutrient sources on soil nutrient status of finger millet under Guni method. The trial was framed out in randomized blocked design with twelve treatments replicated thrice. The results showed that supplement of SWC @ 50% N eq. + EBDLM @ 50% N eq. ha-1 + PG spray @ 3% (T9) had a significant effect on nutrient uptake, fertility status in soil and their values were statistically higher than all the other treatments. The findings of study reported that supplement of SWC @ 50% N eq. + EBDLM @ 50% N eq. ha-1 + PG spray @ 3% (T9) recorded significantly higher uptake of total nitrogen (124.7 kg ha-1), phosphorus (27.2 kg ha-1) and potassium (84.9 kg ha-1). Likewise, the same treatment had recorded superior in available soil nitrogen, phosphorus and potassium (413.8, 44.6 and 223.1 kg ha-1, respectively) compared to other treatments and recommended FYM (10 t)+100:50:50 kg N: P2O5: K2O ha-1 found to be least in soil nutrients and uptake during cropping period of kharif 2019.
