ThesisItem Open Access EFFECT OF DIFFERENT LEVELS OF N AND P FERTILIZERS WITH BIOFERTILIZERS ON YIELD, BIOCHEMICAL PARAMETERS, SOIL PROPERTIES AND NUTRIENT UPTAKE BY CHILLI (Capsicum annum L.) IN LATERITIC SOILS OF KONKAN(dbskkv., Dapoli) DHOPAVKAR, RAJESH VISHNU; Gokhale, N.B.An investigation entitled “Effect of different levels of N and P fertilizers with biofertilizers on yield, biochemical parameters, soil properties and nutrient uptake by chilli (Capsicum annum L.), in lateritic soils of Konkan” was undertaken during Rabi seasons of 2016-17 and 2017-18 at the Research Farm of the Department of Agronomy, College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra. The effect of different levels of N and P fertilizers with biofertilizers on yield, biochemical parameters, soil properties and nutrient uptake by chilli at different growth stages was studied. The field experiment was laid out in the factorial strip plot design, comprising of thirty six treatments replicated three times, comprising of three levels of nitrogen viz. 0 kg N ha-1, 112.5 kg N ha-1 and 150 kg N ha-1, three levels of phosphorus viz. 0 kg P2O5 ha-1, 37.5 kg P2O5 ha-1 and 50 kg P2O5 ha-1and four sources of bio fertilizers viz. No biofertilizer (B0), N fixer- Azotobacter chroococcum (B1), P solubilizer- Aspergillus niger (B2) and N fixer + P solubilizer (B3), with potassium @ 50 kg ha-1 and FYM @ 15 t ha-1 was applied to all the treatments. From field experiment, treatmentwise surface soil samples (0 to 22.5 cm) and plant samples were collected at 30, 60, 90 days after transplanting and at harvest stage. Green pods were collected at maturity stage. The physico-chemical properties of soil such as pH, EC,OC, major nutrients like available N, P2O5, K2O, micronutrients like DTPA extractable Fe, Mn, Zn and Cu and soil biological properties such as microbial count, microbial biomass carbon, microbial biomass nitrogen, urease activity, acid phosphatase activity, dehydrogenase activity, CO2 evolution rate were determined. The plant and pod samples were analyzed for the major nutrients like N, P, K and micro nutrients like Fe, Mn, Zn and Cu. The matured fruits were collected and analyzed for various quality parameters viz., ascorbic acid and capsaicin content. The effect of recommended doses of nitrogen and phosphorus with dual inoculation of biofertilizers increased the plant height, dry matter production, green pod yield over no application of fertilizers. From the interaction effect among the N and P fertilizers and biofertilizers, maximum green pod yield to the tune of 119.8 q ha-1 and 112.7 q ha-1 was obtained in the treatment receiving both the biofertilizers and recommended doses of N and P fertilizer during the year 2016-17 and 2017-18, respectively. Application of doses of N in graded levels significantly increased the ascorbic acid content of chilli pods from 77.82 to 97.33 mg 100g-1 during 2016-17 while it was increased from 76.84 to 96.32mg 100g-1during 2017-18. The application of N @ 150 kg ha-1 and P @ 50 kgP2O5 ha-1 significantly increased the capsaicin contents of chilli fruit over their no application during both the years. Application of recommended doses of nitrogen, phosphorus with inoculation of N fixer and P solubilizer registered maximum available N, P2O5, K2O and micronutrients Fe, Mn, Zn and Cu in soil. Maximum increase in soil biological properties such as microbial count, microbial biomass carbon, microbial biomass nitrogen, urease activity, acid phosphatase activity, dehydrogenase activity, CO2 evolution rate are due to application of both the biofertilizers i.e. N fixer plus P solubilizer along with higher doses of nitrogen and phosphorus. During both the years at harvest of crop significant increase in quantity of CO2 evolution rate to the tune of 37.4 mg CO2/g/h was recorded in the treatment N2P2B2 and 41.80 mg CO2/g/h was in the treatment N2P2B3. Uptake of major as well as micronutrients were increased due to inoculation of both biofertilizers with recommended dose of N and P fertilizers. Potassium uptake was significantly increased due to interaction effects of NP levels and biofertilizers on 30, 60 DAT and A. H. maximum P uptake to the tune of 9.56, 19.26 and 63.66 kg/ha was noticed on 30, 60 DAT and harvesting stage, respectively. Maximum uptake of iron by chilli plants was recorded to the tune of 181.5 g ha-1 in the treatment N2P2B3 receiving recommended doses of both the fertilizers and dual biofertilizers. In general, the study indicated that the application of 150 kg N + 50 kg P2O5 + 50 kg K2O + 10 tons FYM per hectare with the inoculation of N- fixer (Azotobacter chroococcum) and P solubilizer (Aspergillus niger) @ 0.250 kg per hectare each by seedling dip method resulted in yield, and uptake of major and micronutrients with improvement in soil fertility and higher B:C ratio.ThesisItem Open Access EFFECT OF DIFFERENT LEVELS OF N AND P FERTILIZERS WITH BIOFERTILIZERS ON YIELD, BIOCHEMICAL PARAMETERS, SOIL PROPERTIES AND NUTRIENT UPTAKE BY CHILLI (Capsicum annum L.)

Chemistry, Dr.BalasahebSawant Konkan KrishiVidyapeeth, Dapoli, during kharifseason2017. The field experiment was laid out in Factorial Randomized Block Design with 4 levels of nitrogen and silica application viz. N0-0 per centRDN, N1-40 per cent RDN, N2-60 per cent RDN, N3-80 per cent RDN through KAB and Si0-0 kg Si ha-1, Si1-50 kg Si ha-1, Si2-75 kg Si ha-1 andSi3-100 kg Si ha-1through potassium silicate which were replicated three times and total sixteen treatment combinations were taken in the experiment. The initial experimental soil was well drained, sandy clay loam in texture, acidic in reaction with low electrical conductivity and very high organic carbon content. It was very high inavailable N and K2Oand low in available P2O5. The study indicated that, theapplication of 80per cent RDN through Konkan Annapurna Briquettes (KAB) in combination with silica @ 100 kg ha-1placedat7 to 10 cm depth @ one briquettes and one paper packet of potassium silicate for every four hills of rice was founduseful to increase the yield and yield attributing characteristics, grain and straw content of rice, total N, P, K and Si uptake and available N, P2O5, K2O, and Si status of soil. It is therefore concluded that, the placement of Konkan Annapurna Briquettes during kharif season in lateritic soils of Konkan region can reduce the recommended dose of fertilizer to the extent of 20 per centalong with 100 kg silica ha-1 to rice as a basal dose for increasing crop productivity as well as soil fertility.ThesisItem Open Access EFFECT OF DIFFERENT SOURCES OF ORGANIC MANURES AND THEIR COMBINATION ON YIELD AND NUTRIENT UPTAKE BY CHILLI (Capsicum annum L.)

The field experiment was laid out in Randomized Block Design comprising of thirteen treatments replicated thrice. Treatments comprised of T1 [25% N through FYM + 75% N through Urea], T2 [50% N through FYM + 50% N through Urea], T3 [75% N through FYM + 25% N through Urea], T4 [25% N through Vermicompost + 75% N Urea], T5 [50% N through Vermicompost + 50% N through Urea], T6 [75% N through Vermicompost + 25% N through Urea], T7 [25% through N Poultry manure + 75% N through Urea], T8 [50% through N Poultry manure + 50% N through Urea], T9 [75% N through Poultry manure + 75% N through Urea], T10 [25% N through Groundnut cake + 75% N through Urea], T11 [50% N through Groundnut cake + 50% N through Urea], T12 [75% N through Groundnut cake + 25% N through Urea] and T13 [Absolute control]. The initial experimental soil was sandy clay loam in texture, slightly acidic in reaction and low in electrical conductivity. The soil was to be found very high in organic carbon and was low in available N and P2O5. The soil was 47 high in available K2O. DTPA extractable micronutrients (Fe, Mn, Zn and Cu) were found to be 28.86, 114.0, 0.372 and 2.752 (mg kg-1), respectively. It was observed that the substitution of N through poultry manure to the extent of 50 per cent (and remaining 50 per cent through urea) was observed to be the best treatment amongst different combinations of organic manures with urea. It produced highest yield (Green, dry matter of green chilli pod and stover) of chilli and weight of fruit per plant while application of 75 per cent N through Poultry manure and 25 per cent N through urea recorded highest plant height at different stages (i.e. 30, 60 DAT and at harvest). The quality parameter as indicated by ascorbic acid and capsaicin content, the NPK uptake by green pod and stover was also recorded maximum in combined application of organic and inorganic fertilizers. It was also observed that the residual available nutrients in soil also significantly influenced due to integrated nutrient management. It could be concluded from the above investigation that the different combination of poultry manure with urea (50 per cent through poultry manure and 50 per cent N through urea, 75% N through poultry manure and 25% N through urea) was found to be the best treatments in increasing yield (stover and pod) of chilli Var.

MILK, HONEY AND ENRICHED WITH MANGO (Mangifera indica L.) PULP CV. ALPHONSO(2022) SURVE, SHAMIKA VIKAS; Dandekar, V. S.; Desai, B.G.; Gokhale, N.B.; Kasture, M.C.; Joshi, M.S.An investigation was carried out at Dairy Science Laboratory of Department of Animal Husbandry and Dairy Science, College of Agriculture, Dr. B.S.K.K.V., Dapoli (M.S.) to determine the different quality parameters of designed colostrum cake prepared by using milk, coconut milk, white of egg, skim milk powder, honey and mango pulp. The trials were conducted in two phases, in first phase most optimum level of coconut milk and buffalo milk for preparation of colostral mix was determined. In this phase proportion of white of egg and skim milk powder were kept constant (20 & 25%) respectively. Where a sugar was used as sweetening agent. The most acceptable level was determined on the basis of sensory evaluation of product. In second phase this optimum level was used to prepare colostrum cake. However instead of sugar (sucrose) honey was used as sweetening agent and mango pulp was utilized to enhance sensory attributes of product. Factorial Completely Randomized Design (FCRD) was employed by using four treatment combinations viz CH1M1: Most optimum level of colostrum mix + honey @ 20% and Alphonso mango pulp @ 10%, CH1M2: Most optimum level of colostrum mix + honey @ 20 % and Alphonso mango pulp @ 7.5%, CH2M1: Most optimum level of colostrum mix + honey @ 22.5% and Alphonso mango pulp @ 10%, CH2M2: Most optimum level of colostrum mix + honey @ 22.5% and Alphonso mango pulp @ 7.5%. The highest total solids percentage was recorded in treatment combination CH2M2 (45.80%), whereas, lowest (44.70%) in case of CH1M1. Fat content for fresh designed colostrum cake sample was highest (4.86%) in CH1M2 and lowest (4.69%) in CH2M1. Protein content for fresh designed colostrum cake sample was highest (10.27%) in CH1M2 and lowest (9.91%) in CH2M1. Highest total sugar percentage was recorded in CH2M2 (26.11%), and lowest in (25.65%) CH1M1. Highest ash percentage was recorded in CH1M2 (2.12%), and lowest in (2.05%) CH2M1. Highest acidity was recorded in CH2M2 (0.46%) and lowest in case of CH1M2 (0.39%). The highest score for colour and appearance, flavour, body and texture, overall acceptability was observed in CH1M2, (8.41), (8.57), (8.52) (8.63) and lowest in case of CH1M1 for colour and appearance, flavour, body and texture, over all acceptability, (8.10), (8.22), (8.02), (8.14). In the phase II most acceptable product in the present study was observed to be designed colostrum cake prepared by using 20 per cent level of honey and mango pulp @ 7.5 per cent, with overall acceptability score of 8.63. On the basis of sensory evaluation, it has been found that treatment CH1 M2 i.e. colostrum cake prepared by using buffalo milk, coconut milk, white of egg and skim milk powder in proportion of 35, 20, 20 and 25, respectively and blending with honey @ 20% and Alphonso mango pulp @ 7.5% provided best results. Highest Standard plate count was observed in treatment combination CH1M2 increased from initial count of 0.41×104 cfu/g to 15.55×104 cfu/g showed increasing trend and lowest (0.35 x 104 cfu/g to 14.15 x 104 cfu/g ) in CH2M1. Highest yeast and Mould count (0.40 x 101 cfu/g to 5.40 x 101 cfu/g) was observed in CH1M2 and lowest (0.15 x 101 cfu/g to 4.33 x 101 cfu/g) in CH1M2. E. coli was not observed in designed colostrum cake during storage period. As regards to cost of production for best treatments CH1M2 (₹ 210.3/kg) was recorded in case of designed colostrum cake prepared by 20 per cent level of honey and 7.5 per cent mango pulp.ThesisItem Open Access STUDIES ON PHYSIOLOGICAL AND BIOCHEMICAL ASPECTS OF CROP REGULATION IN ALPHONSO MANGO (Mangifera indica L.) UNDER KONKAN CONDITION(Dr.Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2022) PACHPOR, NAGESHKUMAR SAKHARAM; Shinde, A. K.; Mane, A.V.; Savardekar, S. V.; Haldankar, P.M.; Gokhale, N.B.The present study entitled ’Studies on Physiological and Biochemical Aspects of Crop regulation in Alphonso mango under Konkan Condition” was undertaken at Centre of Excellence for Mango, Department of Horticulture Dr. BSKKV, Dapoli, during 2016-2017 and 2017-2018. The experiment was laid out in Randomized Block design consisting of three replications. The investigation consists of three trials to study Effect of foliar feeding of nutrients, plant growth regulators and irrigation on induction of post-harvest vegetative flush, to study effect of foliar application of plant growth regulator and cultural practices on suppression of post monsoon vegetative flush and to study effect of foliar application of nutrients and plant growth regulator to hastening maturity of post monsoon vegetative flush. The present investigation concluded that the foliar application of nutrients and plant growth regulator along with irrigation beneficial for induction of post-harvest new vegetative flush in summer and early harvesting with higher yield. Increase in vegetative flush, flowering intensity and fruit yield over control due to foliar application of 19:19:19 (Foliar grade) 2% with irrigation could be attributed due to the highest rate of photosynthesis (8.43 µ mole CO2/m2/sec), high C:N ratio (21.66) and higher water potential (-1.40 bar). The present investigation helps to conclude that adoption of various cultural practices and plant growth regulator is beneficial for suppression of post monsoon vegetative flush and early induction of flowering and early harvesting. Basin exposure twice in last week of Sept. and Oct (T10) recorded maximum (63.68%) flowering intensity followed by T2- CCC @ 2500 ppm (61.83%) and highest fruit yield (4.90 t/ha), followed by T2- CCC @ 2500 ppm (4.74 t/ha) whereas, minimum flowering intensity (40.72%) and lowest fruit yield (2.34 t/ha) were observed in T1-Control. The foliar application of plant growth regulators after induction of new vegetative shoots after monsoon was beneficial to hastened the maturity of post monsoon vegetative flush and induction of early flowering, better flowering intensity and early harvesting. Among various treatments foliar spraying of PBZ 1000 ppm (T11) was best for early flowering and early harvesting with promising yield. This could be attributed due to the highest rate of photosynthesis (9.69 µ mole CO2/m2/sec), more negative leaf water potential (-2.59 bar) and lowest soil moisture (19.17%), respectively.
