“…A field experiment was carried out during kharif 2013, 2014, 2015 and 2016 at Mandya to study the performance of cowpea under organic production system. The benefit: cost ratio was higher with application of jeevamrutha (2.81) in comparison with other treatments (Yogananda et al, 2019).…”

Correct input use not only aids in achieving higher levels of sustainable production but also,serves to enhance the concentration of organic matter in soils. This reduces the bulk density and compaction. Organic liquid formulations such as jeevamrutha assist in the rapid development of soil fertility by increasing the activity of soil microflora and fauna. These act as both a fertilizer and a biopesticide, and they are crucial in fostering plant growth as well as providing immunity. Jeevamrutha is a type of organic liquid formulation, which is made with readily availableingredients like water, jaggery, pulse flour, and farm wastes like cattle dung and urine. When applied to soil, it creates a friendly microorganismenvironment, which supports the availability of essential nutrients for plant growth. Therefore, this experiment aims to provide an alternative to chemical farming by utilizing jeevamrutha. The experiment was conducted to see how varying concentrations of jeevamrutha affected the growth parameters and yield attributes of the tomato plant. Five treatments with different combinations were laid out with three replications in a factorial randomized complete block design. The results obtained from the experiment revealed that jeevamrutha at a 50% concentration significantly influenced crop growth parameters such as plant height, the total number of leaves, leaf area index, root length, and shoot length. Owing to the improvements in yield attributes such as the total number of fruits per plant, weight, length, and diameter of fruits, using jeevamrutha at 100% increased tomato fruit yield significantly.

“…Whey based jeevamrutha formulation J 4 noted markedly higher number of leaves (8.93 and 12.22) over other treatments of jeevamrutha formulation except J 2 (8.88 and 12.06) at 30 DAS and harvest, respectively. The beneficial effect with application of organic fertilizer such as FYM and jeevamrutha on number of leaves was also shown by Yogananda et al (2020).…”

A split plot experiment was conducted at research farm of Agronomy Section, ICAR–National Dairy Research Institute, Karnal, Haryana during kharif 2018–19 to evaluate various jeevamrutha formulations under the varying nutrient levels in fodder maize (Zea mays L.). In main plot four nutrient levels [Control (0), 50, 75 and 100% RDF] and in sub-plot, five jeevamrutha formulations [Control (without jeevamrutha), water based jeevamrutha @1000 l/ha, water based jeevamrutha @1500 l/ha, whey based jeevamrutha @1000 l/ha and whey based jeevamrutha @1500 l/ha] were taken as treatments and replicated thrice. Better growth attributes, viz. plant height, number of leaves per plant, stem girth and leaf:stem ratio were observed with increased nutrient levels. Application of 50, 75 and 100% RDF resulted in 35.01, 61.21 and 74.19% higher green fodder yield (GFY) over control. Jeevamrutha (whey/water based) formulations significantly improved growth. Significantly higher dry matter yield (DMY) (11.65 t/ha) was obtained with 100% RDF. Whey based jeevamrutha formulation @1500 l/ha ((52.83 and 11.09 t/ha) closely followed by water based jeevamrutha formulation @1500 l/ha (51.38 and 10.79 t/ha) resulted in higher GFY and DMY, respectively. The highest gross returns and net returns were obtained in 100% RDF with whey based jeevamrutha @1500 l/ha (`94.89 and 70.32 × 103/ha, respectively). Maximum benefit:cost ratio (2.89) was recorded in 100% RDF and water based jeevamrutha formulation @1500 l/ha. Interaction effect between jeevamrutha formulation and nutrient levels suggested that application of jeevamrutha formulation @1500 l/ha in both forms (Whey and water) can save 25%nutrient dose.

“…promoted the nutrient supplying capacity of the soil and build-up of more and more soil microorganisms and mineralized organic nitrogen resulting in the production of auxins and gibberellins by PSB which might have also helped in increased root growth, N absorption and higher N content in black gram seed. Additionally, Rhizobium inoculation helped the plant in effective atmospheric N fixation, resulting in higher seed nitrogen content substantially (Bhalu et al 1995;Yogananda et al, 2020).…”

Background: Concerning fertilization, the pulse crops are more responsive to organic manures but indiscriminate and continuous use of chemical fertilizers has venomous effects on physical, chemical and biological properties of the soil thereby affecting the sustainability of crop production, besides causing environmental pollution. Methods: The study aimed at understanding the effect of different organic amendments on nutrient dynamics of black gram (Vigna mungo), which was carried out at the IFS unit, College of Agriculture, Vijayapur, during Kharif-2019 to study the effect of different combinations of organic sources on nutrient availability, nutrient uptake and soil microbial load in black gram. Result: The application of vermicompost + ghanajeevamrutha @ 100% RDP + Rhizobium + PSB recorded significantly higher soil organic carbon (SOC) (0.70%), soil available nitrogen (291.39 kg ha-1), phosphorus (36.30 kg ha-1) and potassium (580.53 kg ha-1) and significantly higher uptake of nutrients i.e., nitrogen (52.07 and 75.43 kg ha-1), phosphorus (10.12 and 16.08 kg ha-1) and potassium (37.67 and 55.42 kg ha-1) at 45 and 75 DAS compared to all other treatments. Similarly, application of FYM + vermicompost @ 100% RDP + Rhizobium + PSB has recorded the highest microbial count of bacteria [24.40 × 106 CFU (Colony Forming Units) g-1], fungi (17.0 × 103 CFU g-1) and actinomycetes (7.50 × 103 CFU g-1), demonstrating the importance of usage of organics for improving the nutrient availability, uptake and microbial load in black gram.
