This study, titled " Enhancing Yield and Quality of Acid Lime through Integrated Nutrient Management in Punjab: A Strategic Approach " was conducted in an organic acid lime orchard in Khadoor, Tehsil Zira, Distt Ferozepur, Punjab, during the 2023-2024 season. The experiment aimed to evaluate the effects of various organic and inorganic nutrient combinations on the growth, yield, quality, and economics of acid lime cultivation. The treatments applied followed a Randomized Complete Block Design (RCBD) with eight treatments and three replications, including combinations of organic manures and recommended dose of fertilizers (RDF). Results showed that treatment T7 (RDF 50% + Vermicompost 50%) significantly enhanced vegetative growth, resulting in a 25.37% increase in tree height, 23.87% increase in tree spread, and a 7.16% increase in trunk diameter. Additionally, T7 produced superior fruit quality, exhibiting the highest fruit length, diameter, peel thickness, total soluble solids (TSS), and ascorbic acid content. The yield parameters were optimal in T7, with the highest number of fruits per tree (741) and the highest fruit yield per tree (47.66 kg). The study concluded that T7, which combines 50% RDF with 50% Vermicompost, is the most effective treatment for improving acid lime yield, quality, and profitability, and offers a sustainable option for acid lime production

Integrated Nutrient Management, Acid Lime and Sustainable Agriculture

In summary, the results of this study provide compelling evidence that integrated nutrient management markedly improves both the vegetative growth and yield attributes of acid lime, while also enhancing key quality parameters. The application of combined organic amendments and inorganic fertilizers, particularly the regimen incorporating 50% RDF with 50% vermicompost, yielded statistically significant improvements in tree height, trunk diameter, and canopy spread, as well as in fruit dimensions, weight, and overall yield. These enhancements are attributable to the synergistic effects of organic amendments, which improve soil structure, nutrient availability, and microbial activity, in conjunction with the rapid nutrient release afforded by inorganic fertilizers. Although certain quality parameters, such as ascorbic acid content, did not exhibit statistically significant differences, trends indicate that integrated nutrient management contributes to improved fruit juice content and total soluble solids. Collectively, these findings underscore the critical role of balanced nutrient management in optimizing crop performance and advancing sustainable production practices in acid lime cultivation, with potential implications for enhanced economic returns and long-term soil health
