Ten treatment combinations viz., T1- 100% RDN, T2- 90% RDN + Panchagavya (5%), T3- 90% RDN + Jeevamrut (5%), T4- 90% RDN + Panchagavya (5%) + Jeevamrut (5%), T5- 80% RDN + Panchagavya (5%), T6- 80% RDN + Jeevamrut (5%), T7- 80% RDN + Panchagavya (5%) + Jeevamrut (5%), T8- 70% RDN + Panchagavya (5%), T9- 70% RDN + Jeevamrut (5%) and T10- 70% RDN + Panchagavya (5%) + Jeevamrut (5%) which were comprised of three bulky organic manures viz., farm yard manure, vermicompost, sheep and goat manure and two liquid organic inputs i.e. Panchagavya and Jeevamrut and two biofertilizers i.e. Azotobacter and phosphorus solubilizing bacteria arranged in randomized block design have three replications. One hundred eighty plants were accommodated in a 2 m x 2 m plots at a spacing of 20 cm x10 cm. Good quality garlic cloves were selected from the seed material and were sown on in thirty plots. Maximum plant height (67.23 cm) , days to harvest (214.33) , clove size (3.08 cm2), number of cloves per bulb (13.82) , bulb weight (53.36 g), bulb diameter (5.03 cm), bulb yield per plot (9.22 kg), bulb yield per hectare (184.33 q) and dry matter content (48.17 %) were observed under T4comprising of 90% RDN + Panchgavya @5% + Jeevamrut @ 5%. Similarly, the maximum soil pH (6.90), EC (0.22 dSm-1), OC (1.66 %), available N (356.33 kg ha-1), available P (53.50 kg ha-1) and available K (443.00 kg ha-1), were recorded under T4. The highest benefit cost ratio of 2.86 was obtained in T4 - 90% RDN + Panchagavya (5%) + Jeevamrut (5%) where Rs. 2,38,628.12 incurred on cost of cultivation and Rs. 6,83,038.55 received at net returns. Therefore the developed nutrient module emphasized in T4 may be adopted and recommended in garlic crop getting for higher productivity and as well as sustained soil healthennullThesis
