ThesisItem Open Access BIOREMEDIATION OF METHANE EMISSION USING METHANOTROPHIC BACTERIA IN PADDY(Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2024-02-23) CHOUDHARY JYOTI; More S. S.; Kasture M. C.; Rajemahadik V. A.; Kadam J. J.An investigation entitled, “Bioremediation of methane emission using methanotrophic bacteria in paddy” was undertaken during kharif, 2022-23 at experimental farm, department of Soil Science and Agricultural Chemistry, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth Dapoli, Dist. Ratnagiri. The field experiment was laid out in the factorial complete randomised design, consisting 16 treatment combinations comprising two factors i.e. four different nutrient source viz, control, recommended dose through chemical fertilizer, recommended dose through konkan Annapurna briquette and gliricidia application and four different methanotrophic consortium viz, control, type I, type II, and type Ib which were replicated three time to study the effect of different nutrient source and methanotrophic bacteria on methane emission, growth, yield parameters, as well as chemical properties and nutrient availability in soil. The experimental soil was lateritic, sandy loam in texture and moderately acidic in reaction. The soil was very high in organic carbon content, medium in available nitrogen, low to medium in available phosphorus and high in available potassium content. The sole application of Konkan Annapurna Briquette (34:14:6 N:P2O5:K2O) along with vermicompost significantly reduced methane flux followed by recommended dose of fertilizer 100:50:50 N:P2O5:K2O kg ha-1. On the other hand, the sole application of glyricidia as green manure along with vermicompost to fulfil the nutrient requirement, encouraged methane flux. The combine effect of nutrient source and methanotrophic bacteria also significantly reduce methane flux in that type I and Konkan Annapurna Briquette (34:14:6 N:P2O5:K2O) application effectively reduce methane flux. On the other hand, application of glyricidia organically without application of methanotrophic bacteria encouraged methane flux. The significantly highest yield attributes like highest grain yield and straw yield was found were application of recommended dose of fertilizer 100:50:50 N:P2O5:K2O kg ha-1 through chemicals fertilizer. Also growth parameter viz. number of tillers, plant height and number of panicles were recorded highest in the treatment recommended dose of fertilizer 100:50:50 N:P2O5:K2O kg ha-1 through chemicals fertilizer was applied. The highest available nitrogen was recorded where 34:14:6 N:P2O5:K2O kg ha-1 through Konkan Annapurna Briquette was applied. The application of recommended dose of fertilizer significantly recorded the highest available potassium content (30 DAT) in soil. Based on the experimental findings, concluded that the application of methanotrophic consortium effectively mitigate methane emission by reducing methane flux, in that Type-I methanotrophic consortium more effectively reduced the methane flux @ 13% compared to green organic manuring and it could be concluded that, the recommended dose of fertilizer through chemicals followed by Konkan Annapurna Briquette can improve nutrient availability, thereby improving yield of the paddy under submerged condition in lateritic soil of Konkan region.ThesisItem Open Access SUPPLEMENTATION OF MODIFIED AMRASHAKTI MULTINUTRIENT SOLUTION THROUGH FOLIAR APPLICATION FOR IMPROVING THE YIELD AND QUALITY OF ALPHONSO MANGO (Mangifera indica L.)(Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2023-12-13) PATIL DIPIKA SUHAS; Deshmukh S. V.; Kasture M. C.; Parulekar Y. R.; More S. S.The present investigation entitled, “Supplementation of modified Amrashakti multinutrient solution through foliar application for improving the yield and quality of Alphonso mango (Mangifera indica L.)” was conducted during June 2022 to May 2023 at Centre of Excellence for Mango, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Ratnagiri (M.S.). The ten treatments; RDF, previous Amrashakti spray and eight modified Amrashkti multinutrient solutions were distributed among three replications and were repeated three times in the experiment. The different combinations of water soluble fertilizers were tested for compatibility and the results were divided into three categories: compatible, least compatible and incompatible.The final8 compatible and clear multinutrient solutions were formulated by using different water-soluble fertilizers and used for the experimental research on mango to attain higher yield. Further, the application of modified Amrashakti multinutrient solution @ 0.5% (Urea, SOP, each) + 0.15% (Phosphoric acid) + 0.25 % (ZnSO4, Borax, CuSO4 each) + 0.0075% (Ammonium molybdate) along with RDF (T4) recorded significantly superior yield (5.56 t ha-1) rest of the treatments. The primary nutrients in leaves viz.,nitrogen, phosphorus and potassium content were discovered to be non-significant during all stages of mango growth but there were numerical differences, which affected the mangoyield and quality. The maximum total zinc and copper content of leaves at marble stage were reported in treatment T2 comprising RDF + Foliar spray @ 0.5% (Urea, SOP, SSP each) + 0.25 % (ZnSO4, Borax, CuSO4 each) + 0.01% (Sodium molybdate) and T6 comprising foliar application of modified Amrashakti @ 1% (Calcium nitrate) + 0.1% (Phosphoric acid) + 0.55% (Potassium nitrate) + 0.25 % (ZnSO4, Borax, CuSO4 each) + 0.0075% (Ammonium molybdate), respectively. At egg stage, the total calcium content of leaves was observed in the treatment T6 receiving foliar application of modified Amrashakti @ 1% (Calcium nitrate) + 0.1% (Phosphoric acid) + 0.55% (Potassium nitrate) + 0.25 % (ZnSO4, Borax, CuSO4 each) + 0.0075% (Ammonium molybdate). However, the maximum total zinc and copper content was observed with the application treatment T9 i.e. foliar application of0.5% (Urea, SOP, each) + 0.1% Phosphoric acid + 0.25 % (ZnSO4, FeSO4, MnSO4, CuSO4 each) + 0.2% (Microsil) + Water soluble Calcium @ 0.2 %. Treatment T4, which consisted of foliar spray of 0.5% (Urea, SOP, each) + 0.15% (Phosphoric acid) + 0.25% (ZnSO4, Borax, CuSO4 each) + 0.0075% (Ammonium molybdate), considerably enhanced the nutritional content of total iron and manganese in fruit pulp.Since the treatments were applied by foliar feeding, the non-significant effect was observed on the soil properties.ThesisItem Open Access In vitro shoot development from callus and other explants in teak (Tectona grandis Linn.f.)(Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2023-12-27) Shinde Pratik Suresh; Deshpande R. S.; Mane A. V.; Sawardekar S. V.; Rane A. D.The present investigation on “In vitro shoot development from callus and other explants in Teak (Tectona grandis Linn.f.)” was carried out at the Plant Biotechnology Centre, College of Agriculture, Dapoli, Dist. Ratnagiri 415 712 (Maharashtra). Among the matured and juvenile explants used, apical buds and nodes from juvenile plants were found best for shoot induction.
