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 INFLUENCE OF INTEGRATED NUTRIENT MANAGEMENT ON SOIL CARBON POOLS, SOIL PROPERTIES, YIELD, QUALITY AND NUTRIENT UPTAKE BY LABLAB BEAN (Lablab purpureus L.) IN ALFISOLS OF KONKAN REGION OF MAHARASHTRA(Dr.Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2022-11) KARWADE, SHIVANI GAGAN; Vaidya, K. P.; Dodake, S. B.; Salvi, B. R.; More, V. G.field experiment was conducted to study the influence of integrated nutrient management of fertilizers, manures and biofertilizers on soil carbon pools, soil properties, yield, quality and nutrient uptake by lablab bean (Lablab purpureus L.) in Alfisols of Konkan region of Maharashtra at Department of Agronomy, Dr.B.S.K.K.V, Dapoli during Rabi 2020-21 and 2021-22 in Split Plot Design (SPD) comprising fifteen treatment combinations replicated thrice and compared with an extra treatment of absolute control laid out of experimental plot to judge the fate of native nutrients of lateritic soil of Konkan. The results of the manures and fertilizers application indicated that the equal integration of RDN through fertilizers and RDN through poultry manure (F5) and in case of biofertilizers, seed inoculations of phosphorus solubilizing bacteria @ 5 mL kg-1 and vesicular arbuscular mycorrhiza @10 g kg-1 seed (B3) to lablab bean recorded the highest yield, growth attributing characters namely dry matter and nodulation, quality parameters namely protein and chlorophyll content, macronutrients (N and P) content and uptake by seed, stover and total uptake by lablab bean and nitrogen and phosphorus availability of soil. The significantly highest values of potassium (K) and micronutrients (Fe, Mn, Zn and Cu) content and uptake by seed, stover and total uptake by lablab bean as well as their availability, biological properties and organic carbon pools of soil were recorded in the treatment receiving the application of 100 % RDN through poultry manure (F3) and seed inoculation of phosphorus solubilizing bacteria @ 5 mL kg-1 and vesicular arbuscular mycorrhiza @10 g kg-1 seed (B3). Conjoint use of RDN through fertilizers and RDN through poultry manure with the blend of seed inoculation of phosphorus solubilizing bacteria @ 5 mL kg-1 and vesicular arbuscular mycorrhiza @10 g kg-1 seed (F5B3) recorded the significantly highest dry matter, available macronutrients (N and P2O5) status and macronutrients (N and P) content and uptake by seed, stover and total uptake by lablab bean. However, all the interactions of manures and fertilizers in conjunction with biofertilizers could not reach to the level of significance in case of particle density, bulk density, maximum water holding capacity (MWHC), mechanical composition of soil, pH, EC, organic carbon, available potassium, micronutrients (Fe, Mn, Zn and Cu) status, microbial population, acid phosphatase activity and organic carbon pools of soil. The result of the present investigation indicated that for getting maximum yield of lablab bean and fetching highest net returns as well as for improving the soil health, the equal integration of RDN through fertilizers and RDN through poultry manure (PM) with a blend of seed inoculations of phosphorus solubilizing bacteria (PSB) @ 5 mL kg-1 and vesicular arbuscular mycorrhiza (VAM) @10 g kg-1 seed (F5B3) was found to be beneficial in lateritic soils of Konkan during Rabi season.ThesisItem Open Access STUDIES ON EFFICACY OF ORGANICS THROUGH SOIL AND FOLIAR APPLICATION ON SOIL PROPERTIES AND YIELD OF CHILLI (Capsicum annuum L.) IN LATERITIC SOIL(Dr.Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2022-10-07) Mhetre, Akash Gajanan; Salvi, V.G.; Kasture, M.C.; Salvi, B.R.; Bodake, P.S.Field experiments entitled “Studies on efficacy of organics through soil and foliar application on soil properties and yield of chilli (Capsicum annuum L.) in lateritic soil” were conducted at Department of Agronomy, College of Agriculture, Dapoli during Rabi, 2020-21 and 2021-22. Chilli cv. Sitara was taken as test crop with a spacing of 60 cm x 45 cm with gross plot size of 4.5 m x 3.0 m. The experiment was laid out in Randomized Block Design (RBD) comprising sixteen treatment combinations which were replicated thrice. The vermicompost was applied to soil on the basis of 100 per cent recommended dose of nitrogen alongwith the foliar application of three levels of cow urine, vermiwash, moringa leaf extract, glyricidia leaf extract and pongamia leaf extract @ 0.02, 0.04 and 0.06 per cent N content. The foliar application was carried out at 30, 60 and 90 DAT and the observations were recorded at vegetative, reproductive and at harvest of chilli. The study was undertaken with the aim to assess the suitability of vermicompost as well as to find out suitable organic source for foliar application to chilli crop using different organic sources under organic farming practises. The results of the present investigation clearly indicated that, the different treatment combinations have not shown any significant differences on soil properties. However, those properties were found to be improved over initial content due to application of vermicompost and FYM. The application of 100 per cent RDN through vermicompost alongwith foliar application of vermiwash @ 0.06 per cent N content (T7) significantly improved growth, yield and yield attributing characters viz., plant height, weight of fruit per plant and green pod yield of chilli. Treatment T7 was followed by treatment T4 receiving application of 100 per cent RDN through vermicompost alongwith foliar application of cow urine @ 0.06 per cent N content and treatment T10 comprising 100 per cent RDN through vermicompost alongwith foliar application of moringa leaf extract @ 0.06 per cent N content in improving growth, yield and yield attributing characters of chilli. Regarding the quality parameters viz., ascorbic acid, capsaicin and anthocyanin content as well as nutrient content and uptake of chilli were significantly enhanced due to the application of vermicompost on 100 per cent N equivalent basis alongwith foliar application of vermiwash @ 0.06 per cent N content (T7). It was followed by the treatment T6, T4 and T10 consisting application of 100 per cent RDN through vermicompost to each treatment alongwith foliar application of vermiwash @ 0.04 per cent N content, cow urine @ 0.06 per cent N content as well as moringa leaf extract @ 0.06 per cent N content, respectively with few exceptions. From the above results, it was also observed that the application of 100 per cent RDN through vermicompost to soil alongwith foliar application of animal originated organic sources viz., vermiwash @ 0.06 per cent N content followed by cow urine @ 0.06 per cent N content improved the soil properties and plant growth parameters as compared to the plant leaf extracts. As far as the different plant leaf extracts were concerned, the application of 100 per cent RDN through vermicompost and foliar application of moringa leaf extract @ 0.06 per cent N content was found as a good source for plant nutrition. From the overall study it could be concluded that, the application of 100 per cent recommended dose of nitrogen through vermicompost alongwith the foliar application of vermiwash @ 0.06 per cent nitrogen content was the best combination to provide optimum plant nutrition. It has potential to improve soil properties and to exploit the maximum growth, yield attributing characters, yield and quality of chilli as well as to get profitable income under organic farming practises in Rabi season on lateritic soils of Konkan region.ThesisItem Open Access Periodical changes in nutrient status under different cultivation practices and various crops in alfisols of konkan region(2022-11-29) Syeda, N.S.; Salvi, V.G.; More, S.S.; Rejemahadik, V.S.; Rathod, R.R.; Khobragade, N.H.ThesisItem Open Access STUDIES ON CARBON SEQUESTRATION UNDER BAMBOO BASED AGROFORESTRY SYSTEM IN ALFISOL(Dr.Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2022-11-30) MORE, DEVESH DILIP; MESHRAM, N.

Tu-Ss + Cs (8 m X 8 m Alpinia) and Ti-Ss+ Ca(8 m X 8 m + Finger millet). The results S emerged out indicated that the carbon sequestration, soil fertility. growth parameter, ix x yields of crops and economics were significantly influenced by the spacing and crops levels within different treatments combination. Among the treatment combination, (T9) S3-8 x 8 m2 + C1-Turmeric + bamboo based agroforestry system was found to be significantly superior to other agroforestry system. Build-up of more carbon sequestration was achieved by the spacing 8 x 8 m2 with turmeric crops under bamboo based agroforestry system for developing bio-stability in soil and environment which helps to maintain soil health and balancing environment. Less carbon sequestration, soil fertility, growth parameter, yields of crops and economics as compare to others by may be due to crop competition and less productivity. The more carbon content under agroforestry system and maximum gain of diameter at breast height (DBH) of bamboo. Height and all the yields of intercrops (Turmeric, Ginger, Alpinia, Finger millet) were recorded more by the treatment combination, (T9) S3-8 x 8 m2 + C1-Turmeric + bamboo based agroforestry system than other. However, the maximum equivalent yield of bamboo was achieved by bamboo based turmeric agroforestry system with wider standard spacing of bamboo 8 x 8 m2 . Overall improvement in physicochemical properties of soil (BD, MWHC, pH. EC, OC, NPK), carbon sequestration (components viz. TOC, TC, Plant carbon, TSC, TCSR, PCS, SCS, respectively) and yield by bamboo based turmeric agroforestry system with wider standard spacing of bamboo 8 x 8 m2 . The maximum influenced of growth parameter and crop yields were recorded by wider spacing of bamboo 8 x 8 m2 may be due to optimum photosynthesis and less crop competition. As per the market demand and high value products, bamboo based turmeric agroforestry system is economically most feasible for the farmers. Overall, among the agroforestry systems, bamboo based turmeric agroforestry system with 8 x 8 m2 spacing was found to be significantly superior with respect to carbon sequestration, soil fertility, growth parameter, biomass, yield of crops, equivalent yields and economics than alpinia, ginger and finger millet + bamboo based agroforestry systems in Alfisol.ThesisItem Open Access Studies on different forms of potassium under cluster bean (Cyamopsis tetragonoloba (L.)
