    Studies on Oil Content and Quality of Eucalyptus pellita In Agro-Climatic Zone-9 of Karnataka
    (UAS, Dharwad, 2011) Shambulingappa M. Utalenavar; H.M. Vamadevaiah
    A study was conducted in the established 4 year old Eucalyptus pellita F. Muell plantations in four sites of Agro-climatic Zone-9 of Karnataka in 2010-11 which comes under two districts Shimoga and Uttar Kannada which known for extensively established plantations of E. pellita. Being Hilly Zone it provides a wide variation in climatic, topographic and edaphic factors. The present study was aimed at assessing the growth and productivity, soil properties and quantity and quality of leaf oil under different site conditions. All the sites were classified based on the rainfall and altitude. The analysis of variance showed significant effect of site conditions on various growth and productivity parameters, Teerthahalli plantations showed superiority in growth (DBH 23.44 cm) and also good performance in productivity viz., basal area (35.35 m2/ha) and total volume (360 m3/ha) as compared to other experimental sites. The soil under plantations exhibited better physical and chemical properties as compared to their respective control sites. The highest leaf oil yield was from Sorab (0.44%). The colour of oil from Sammasagi and Sorab was yellow, while it was pale yellow for Sagar and Teerthahalli. The leaf yield varied from 5.685 (Sammasagi) to 13.115 t/ha (Teerthahalli) in all the sites. The Sagar site had highest leaf oil (41.25 lit/ha) as compared to other sites. Sagar recorded highest value of Rs.78,299/ha as compared to other sites. The Eucalyptol leaf oil content was highest in Sagar (71.68%) as compared to other sites. Among the experimental sites, Sagar site showed superiority in total height (14.80 m), bole height (12.71 m), leaf biomass (10,355 kg/ha), oil yield (41.5 lit/ha), 1,8- Cineol (71.68%). At the Sagar site, eight chemical components were determined from E. pellita leaf oil, which contained Eucalyptol (71.68%), a–Pinene (17.43%), a-terpeniol (3.29%), Geraniol (2.05%), b–Pinene (1.25%), bi-Fenchol (1.24%), b-Selinene (0.94%) and Globulol (0.49%).

    Biochemical Studies on Homa Organic Farming Practices in Cabbage (Brassica oleracea var. Saint)
    (UAS, Dharwad, 2011) Hattalli Sachin Amrutraya; P.W. Basarkar
    A field experiment laid out in Completely Randomised Block Design with 13 treatments replicated thrice was conducted during kharif 2010 to study the biochemical studies on Homa organic farming practices in cabbage (Brassica oleracea var. Saint). The conventional control (CC) and control without homa (CWH) were maintained almost 1 km away. The soil type was red black. All the seedlings were grown on raised beds, transplanted after one month and were given fresh cow dung and cow urine as basal treatment except absolute control, CC and CWC. The non-homa ash was collected after burning the agricultural waste. Agnihotra homa (AH) was performed at sun rise and sun set and Om Tryambakam homa (OTH) was performed for 3-4 h daily during experimental period. A special bio-digester called Gloria Biosol was prepared which contained AH ash. The non-homa ash, AH ash, OTH ash and Gloria Biosol were used for soil and foliar application. Soil and foliar application of Gloria Biosol was significantly superior over organic control in plant height, number of outer leaves per plant, leaf area, number of inner leaves per head and yield attributes, microbial population in soil, increase in the activities of soil dehydrogenase (15-54%) and soil phosphatase (6-18%), soil N, K, Cu and Mn and cabbage TSS (41%), ascorbic acid (11%), phenols (18%), crude protein (16%), N (16%), S (71%), K (22%), P (22%), Cu (13%), Zn (8%), Mn (9%) and Fe (4%) showed significant increase over organic control. Soil and foliar application of AH ash significantly increased soil P, Zn and Fe. Significant reduction was observed in the incidence of black rot (29-55%), black spot of leaf (39-73%), insect attack (head borer(18-69%), diamond back moth larvae (25-64%) and Spodoptera litura larvae (40-62%) per plant due to soil and foliar application of Gloria Biosol and different homa treatments.

    Response of Tomato (Solanum lycopersicum L.) to Homa Organic Farming Practices
    (UAS, Dharwad, 2011) Brunda R.; P.W. Basarkar
    A field experiment laid out in completely randomised block design with 11 treatments exposed to Homa atmosphere replicated thrice was conducted during kharif 2010 to study response of tomato (solanum lycopersicum L.) to homa organic farming practices. The conventional control (CC) and control without Homa (CWH) were maintained almost 1 km away. The soil type was sandy loamy. All the seedlings were grown on raised beds, transplanted after one month and were given fresh cow dung and cow urine as basal treatment except absolute control, CC and CWC. Nonhoma ash was collected after burning the agricultural waste. Agnihotra homa (AH) was performed at sun rise and sun set and Om Tryambakam homa (OTH) was performed for 3-4 h daily during experimental period which yielded smoke and ash. A special bio-digester called Gloria Biosol was prepared which contained AH ash. The Non-homa ash, AH ash, OTH ash and Gloria Biosol were used for soil and foliar application. Soil and foliar application of Gloria Biosol was significantly superior over organic control in plant height, number leaves, number of branches, root length, yield attributes, microbial population in the soil, increase in the activities of soil dehydrogenase (5-52%) and soil phosphatase (2-34%), soil N and K and micronutrients, Cu and Mn and quality parameters like lycopene (40.69%), phenol (7.28%), ascorbic acid (49.05%), TSS (10.2%) and total sugar (9.68%) showed significant increase. Soil and foliar application of AH ash increased soil phosphorus and micronutrients, Zn and Fe. Shelf life of tomato fruits increased by 7-12 days due to different homa treatments as compared to organic and conventional control. Incidence of Leaf spot and insect attack was reduced significantly (37.2% - 40.17%, respectively) due to soil and foliar application of Gloria Biosol which was superior over homa ashes and control.
