Abstract:

Context: -Overuse of chemical fertilizers reduces soil fertility, which highlights the need to
switch to integrated farming practices for sustainable growth.
Purpose: – A field experiment was conducted to analyse the effects of various integrated
nutrient management strategies on soil fertility generally, nutrient level fluctuations in the
soil, plant uptake, and nutrient content and economic consequences in lentil farming.
Method: – Eight different treatments representing various nutrient sources were used in the
experiment, which used a Randomized Block Design. Each treatment had three replications.
Result: – The results indicated that there was no significant difference among 8 different
treatments for soil pH and EC. The available nitrogen, available phosphorus and available
potassium in soil and content in straw and seed were found highest in T 8 while protein
content in seed was also found highest in T 8 (24.85 %) followed by T 7 (24.50 %). But the
economics of cultivation indicated T 4 to be the best with the highest B:C ratio (1.96).
Conclusion: – The proper and balanced usage of organic and inorganic sources of nutrient
increased soil accessible nutrient pool and there was abundant of the remainder of nutrient in
the soil. The impact of combined RDF, rhizobium, vermicompost and FYM may be the
reason in higher nutrient content in soil, plants and quality of lentil.
Implication: – The practice of integrated nutrient management strategies are for improving
lentil cultivation's soil fertility, nutrient uptake, protein content, and overall economic
viability.
