Effect of nutrient management through biomanuring on morpho-qualitative traits and productivity of turmeric. Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Ph. D. 2022. Print. xxii, 265p. (Unpublished).https://krishikosh.egranth.ac.in/handle/1/5810204839A field experiment entitled “Effect of nutrient management through bio-manuring on morpho-qualitative traits and productivity of turmeric” was conducted at Certified Organic Farm, Centre of Organic Agriculture Research and Training (COART), Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2020-21 and 2021-22. The soil of experimental site was clayey in texture and slightly alkaline in reaction, medium in organic carbon content, low in available nitrogen and phosphorous while very high in exchangeable potassium. The both year of experiment was same site and location. The turmeric plantation on broad bed furrow by using pair row system in which spacing of turmeric was kept as 30 cm with 30 cm. The promising turmeric variety PDKV waigaon was used for experimentation. The specific objective of the study was to investigate the best nutrient management through biomanuring combination for productivity and quality of turmeric. Said experiment was laid out in randomized block design replicated thrice with nine treatments consisting of nutrient management through biomanuring which equates with RDF levels of turmeric through various organic sources in combination viz., T1 – Absolute Control, T2 – 25% Neemcake + 25% Cowdung slurry + Biofertilizers, T3 – 25% Vermicompost + 25% Biogas slurry + Green manure at 60 DAS, T4- 25% Vermicompost + 25% Jeevamrut + Biofertilizers + Green manure at 60DAS, T5 – 25% Vermicompost + 25% Neemcake + 25% Biogas slurry, T6 – 25% Vermicompost + 25% Neemcake + 25% Jeevamrut, T7 – 50% Vermicompost + 50% Neemcake + Biofertilizers, T8 – 50% Vermicompost + 50% FYM + Biofertilizers and T9 - 100% Vermicompost. The both year experimentation results revealed that, application of 50% Vermicompost + 50% Neemcake + Biofertilizers which equated with 100% RDF registered significantly the highest growth attributes such as plant height (cm), number of leaves, leaf area (cm2), number of tillers, chlorophyll index and leaf dry matter (g) of turmeric than other treatments of nutrient management through bio-manuring and being parallel with application of 50% Vermicompost + 50% FYM + Biofertilizers and 100% Vermicompost which equated with 100% RDF. Through both year of experiment and in pooled data analysis, yield attributes such as number, length (cm), girth (cm) and weight (g) of mother rhizome, primary rhizome and secondary rhizome recorded significantly highest with application of 50% Vermicompost + 50% Neemcake + Biofertilizers than other treatments of nutrient management through bio-manuring and being corresponding with application of 50% Vermicompost + 50% FYM + Biofertilizers and 100% Vermicompost. Also, in both year of experiment and in pooled data analysis the yield attributes such as weight of tertiary rhizome (g), total weight of rhizome (g) per plant and dry matter (g) per plant recorded significantly highest with application of 50% Vermicompost + 50% Neemcake + Biofertilizers than other treatments of nutrient management through bio-manuring and comparable with application of 50% Vermicompost + 50% FYM + Biofertilizers and 100% Vermicompost. The fresh rhizome yield (q ha-1) and dry rhizome yield (q ha-1) found significantly maximum with application of 50% Vermicompost + 50% Neemcake + Biofertilizers than other treatments of nutrient management through bio-manuring and at par with application of 50% Vermicompost + 50% FYM + Biofertilizers and 100% Vermicompost during both year of experiment and in pooled data also. The quality attributes such as curcumin content (%), oleoresin content (%) and essential oil content (%) of turmeric differences among the various combination of nutrient management found to be significant. The combined application of 50% Vermicompost + 50% Neemcake + Biofertilizers recorded significantly higher soil biological and microbial activity than other application of biomanuring. The significant increase in organic carbon recorded with application of 50% Vermicompost + 50% Neemcake + Biofertilizers. The available macronutrients (N, P and K) and micronutrients (Fe, Zn, Cu and Mn) found to be significant among the different practices of nutrient management through biomanuring. The physical properties of soil in turmeric field such as bulk density, particle density, porosity, field capacity, permanent wilting point and available water capacity found to be non-significant during the both year of experiment. However, improvement observed over initial status due to practices of application of biomanures. The uptake of macronutrients (N, P and K) and micronutrients (Fe, Zn, Cu and Mn) by turmeric rhizome and plant recorded higher with combined application of 50% Vermicompost + 50% Neemcake + Biofertilizers and found significantly superior than other treatments of nutrient management through bio-manuring. The treatment with application of 50% Vermicompost + 50% Neemcake + Biofertilizers recorded highest gross monetary return, net monetary return and B: C ratio and found superior over other treatments of nutrient management through biomanuring. The energy parameters in turmeric were improved with application of nutrient management through biomanuring and maximum energy output and energy balance was obtained with application of 50% Vermicompost + 50% Neemcake + Biofertilizers. However, higher values of energy balance per unit input and energy output per unit input ratio were registered with application of 50% Vermicompost + 50% Neemcake + Biofertilizers.EnglishThesis
