(College of Horticulture, Bengaluru)., 2021-01) H. M. PRUTHVI RAJ; B. N. DHANANJAYA; ALUR, ASHOK S.; B. G. PRAKASH; R. L. RAGHUNATHA REDDY; B. R. PREMALATHAA study was undertaken to assess the fertility status of surface soils under different periods of eucalyptus cultivation (12, 24 and 48 years) and restoration (2, 6 and 10 years) and compared with adjacent croplands having no history of eucalyptus cultivation. The results revealed that the soils under eucalyptus plantation showed high bulk density and low water holding capacity as compared to restored and cropland plots. Further, bulk density was increased while water holding capacity was decreased with increasing the cultivation period of eucalyptus. Soils under eucalyptus plantation were acidic in reaction and contained less total soluble salts. The soil acidity was increased while total soluble salts content was decreased with prolonging the cultivation period of eucalyptus. The available major nutrients except sulphur and total bacterial and actinomycetes counts were low in soils under eucalyptus plantation and were decreased with prolonging the cultivation period of eucalyptus. The available Fe, Mn, Zn and Cu contents including total fungal counts were relatively more in soils under eucalyptus plantation than restored and cropland plots and were increased with prolonging the period of eucalyptus cultivation. A study on vertical distribution of nutrients in eucalyptus, restored and cropland plots indicated that the available major and micronutrients contents were decreased with depth except Mn content. A study on allelopathic effect of eucalyptus tree parts aqueous extracts on seed germination and seedling growth of finger millet and tomato revealed that the germination of tomato seeds was more inhibited than finger millet seeds. Further, fresh leaves aqueous extract has pronounced more inhibitory effect on seed germination and seedling growth attributes of finger millet and tomato followed by consortium of fresh leaves, juvenile stem bark and root extracts while least inhibition was noticed in root extract at all levels of concentration tried.ThesisItem Open Access EFFECT OF FOLIAR SPRAY OF POTASSIUM AND MICRONUTRIENTS ON GROWTH, YIELD AND QUALITY OF PAPAYA (Carica papaya L.) cv.

N., DHANANJAYA; A. P., MALLIKARJUNA GOWDA; K. J., DAYAMANIBiochar application in horticulture has been proved positive crop response, improved soil properties along with mitigation of climate change. The present study was conducted at Regional Horticulture Research and Extension Centre, UHS campus, GKVK, Bengaluru during kharif 2017-18. The study was aimed to standardize the biochar production methods by using different feedstock materials and its effect on performance of okra. Biochar was produced by adopting two methods, namely heap and drum method by using different feedstock materials viz., coconut husk, coconut midrib, arecanut husk and Prosopis juliflora. Among different production methods and feedstock materials, coconut husk was showed maximum recovery percentage and maximum water holding capacity in drum method compared to heap method. The coconut husk biochar was enriched with organics (Cowdung slurry and cow urine) and inorganics (NPK: 19:19:19 and NPK: 19:19:19+Zn+B) at 1:1 ratio and were analyzed for various physical and chemical properties. Among different materials, coconut husk biochar enriched with cowdung slurry was recorded statistically higher nutrient status compared to other enriched materials. Enriched biochar was incubated with different soils viz., acid, alkaline and experimental (neutral) soils at different doses viz., 2.5, 5.0 and 7.5 t ha-1 with control for 120 days at field conditions. The treatment which received enriched biochar @ 7.5 t ha-1 has shown the significantly higher nutrients content and possessed better physical properties after 120 days of incubation in all soils. Further, biochar acts as soil amendment in reclaiming both acidic and alkali soils by bringing the soil pH to neutrality. The application of enriched biochar @ 50% FYM + 100 % NPK has enhanced the growth and yield attributes of okra in field experiment. At harvest, it was also found that the treatment which received only biochar at all three levels has increased the available nutrients content of soil as compared to initial values of experiment.ThesisItem Open Access RESOURCE INVENTORIZATION FOR WATERSHED PLANNING OF MASKAL-1 AND SANTPUR MICRO-WATERSHEDS OF AURAD TALUK IN BIDAR DISTRICT(University of Horticultural Sciences, Bagalkot (COLLEGE OF HORTICULTURE, GKVK POST, BENGALURU), 2018-07) S., RASHMI; M., SHIVANNA; ALUR, ASHOK S.; M., ANJANAPPA; S., ANIL KUMAR; B. N., DHANANJAYA; NAIKODI, PRAVEEN KUMAR B.A study was undertaken to inventorize, characterize and map the soil resources of two micro- watersheds derived from basalt in North Eastern Transitional Zone of Karnataka (Zone -1 ) in order to assess their land capability and suitability for crops and also to assess soil fertility constraints.ThesisItem Open Access RESOURCE INVENTORIZATION FORWATERSHED PLANNING OF HUMNABAD SUB-WATERSHED OF HUMNABAD TALUK IN BIDAR DISTRICT(University of Horticultural Sciences, Bagalkot (COLLEGE OF HORTICULTURE, BENGALURU), 2018-07) C., THEJASWINI; ALUR, ASHOK S.; M., SHIVANNA; S., ANIL KUMAR; S. J., PRASHANTH; B. N., DHANANJAYA; NAIKODI, PRAVEEN KUMAR B.A study was undertaken to characterize and map the soils under Humnabad sub-watershed in North Eastern Transitional Zone (Zone- 1) of the Karnataka in order to assess their resource potential i.e., land capability, suitability for different crops, resource conservation plans and also to assess soil productivity constraints of the area. Eighteen representative soil series were studied in detail. The soil were described in the field for their morphological properties and later analyzed in laboratory for their physical and chemical properties and further classified up to series level. The identified land capability sub-classes namely; IIse, IIwe, IIIse and IVse have been differentiated and mapped. Based on the Land Capability Classification (LCC) conservation measures were recommend like crescent bund, trench cum bunding, bench terracing etc., for shallow soils with severe erosion and undulating topography. Whereas, for more deep to very deep soils, clayey in texture and prone to slight to moderate erosion graded bunds or strengthening of bund were recommended. The mapped soils from the study area were matched with the soil suitability criteria for few important crops like pigeonpea, soybean, mango, guava, sapota and cashewnut. According to different soil series some of them were not suitable, highly suitable, marginally suitable, and moderately suitable due to the limitations of rooting depth, texture and slope. Surface samples (464) were collected from at a grid interval of 320 m and analyzed for fertility status. The soil pH content was neutral to moderately alkaline in reaction and non-saline in nature. Soil organic content was low to high. Available nitrogen, phosphorous and sulphur were low to medium. All micronutrients were sufficient except zinc.ThesisItem Open Access RESPONSE OF TOMATO (Lycopersicum esculentum) TO PHOSPHORUS AND SULPHUR APPLICATION IN CALCAREOUS SOIL(University of Horticultural Sciences, Bagalkot, 2014-09) P. R., KALPANA; R., SUMA; M. S., NAGARAJA; ALUR, ASHOK S.; N., BASAVARAJ; GANDOLKAR, KANTESHTomato is an important commercial vegetable crop of Bagalkot, is also known to tolerate the calcareous soil conditions. Phosphorus (P) availability is one of the major constraints affecting its quality and productivity. Application of sulphur (S) is known to enhance P availability through bio-chemical reactions and desorption process. Hence, to study the quantity of P and S required to enhance the productivity of tomato (Arka Ananya), a field experiment was conducted in calcareous clay loam soil at RHREC, Bagalkot during kharif 2013. The treatments comprised of five levels of P2O5 (125, 100, 75, 50 and 0% RDP) and four levels of S applied at the rate of 2.5, 1.5, 0.5 and 0 per cent (w/w) equivalent to active CaCO3. Application of S with or without P resulted in increased availability of P, S and DTPA- Fe, Zn, Mn and Cu in soil upto 40 DAP. However, later they decreased with advancement of crop growth. But, application of P without S enhanced the availability of P alone, while all other nutrients decreased. Application of 100% RDP + 2.5% S increased the concentration of total S, K, Mg, Fe, Zn and Mn in both leaves and fruits. However, application of 125% RDP + 2.5% S recorded highest total P, N and Cu, while, lower rates of P and S recorded higher concentration of Ca. Application of 125% RDP + 2.5% S enhanced tomato plant height (86.53 cm), internodal length (7.54 cm), number of branches (9.75) and flower per cluster (7.49). However, fruit setting rate (69.37%), number of fruits per cluster (4.94), fruits per plant (41.17), fruit weight (77.60 g) and fruit diameter (5.17 cm) were found highest in 100% RDP + 2.5% S. Present study indicated that the application of 100% RDP + 2.5% S was best to obtain maximum tomato fruit yield (3.19 kg plant-1 and 42.30 t ha-1) and quality viz., TSS (4.17°Bx), ascorbic acid (17.43 mg 100 g-1) and b-carotene (3.61 mg 100 g-1).ThesisItem Open Access STUDIES ON REGULATION OF ALTERNATE BEARING, FRUIT YIELD AND QUALITY IN MANGO (Mangifera indica L.) cv.
