Title: Soil fertility status of major nutrients, micronutrients and mapping in Nicchapura-2 micro watershed of Davanagere district, Karnataka
Biography:
Parashuram Chandravasnshi has expertise in Soil Nutrient Management, and having experience in teaching, research and extension methodology adopted for soil sampling and developed soil information system for nutrient and cropping pattern. In 11 years of experience, he has published more than 25 research papers and attended 15 international and national conferences especially on soil fertility and sustainability.
Abstract:
The investigation was conducted to study the soil fertility status of available macro and micronutrient in Nicchapura-2 micro watershed of Davanagere district. 103 soil samples were collected grid-wise by using cadastral map of study area and were analyzed for their fertility. The value of pH, electrical conductivity, and organic carbon was ranged from 6.2 to 8.7, 0.11 to 0.84 dS m-1 and 3.1 to 5.6 g kg-1 respectively. The available N, P2O5, K2O, was ranged from 135 to 236 kg ha-1, 10 to 34 kg ha-1,130 to 415 kg ha-1, 8.1 to 38.1 cmol (p+) kg-1, 6.3 to 26.2 cmol (p+) kg-1 and 6.3 to 12.1 ppm respectively. Available micronutrients iron, manganese, zincs and copper was ranged from 0.58 to 5.92 mg kg-1, 0.60 to 10.83 mg kg-1, 0.01 to 0.41 mg kg-1, 0.06 to 4.81 mg kg-1 respectively. Available micronutrients such as zinc and iron are deficient but copper and manganese were sufficient in these soils of micro-watershed. The study concluded that available nutrients content are low to medium in red soils. The black soils show high phosphorus than red soils. These variations of phosphorus in soils may be due to variation in soil properties like clay content, CEC and P fixation capacity. The exchangeable Ca and Mg content were sufficient surface samples. Low in available sulphur content may be because of acidic reaction, low EC and OC values in both black and red soils. Available micronutrients such as zinc and iron are deficient but copper and manganese were sufficient in these soils of micro-watershed.

Title: Site specific major nutrient variation maps through GIS and recommendations for coconut gardens of farmers in different agro climatic situations
Biography:
Dinesh Kumar M is working as a Professor and Head in Department of Agronomy. He has been serving for the university for the past 30 years. He got vast experience in research and teaching along with extension work. He has expertise in nutrient management aspects and guided more than 10 students. Presently, he is working in precision aspects of inputs for crop management. He has published 100+ papers in national, international journals and also participated in national and international symposiums.
Abstract:
Karnataka state stands third in India for coconut accounting 13.83 per cent of the country's production. At present, there is uniform recommendation of major nutrients (170:120:400 and 330:200:800 g NPK for young and old palm) across soils of various agro-climatic zones. Farmers are practicing blind application of fertilizers based on many other considerations than plants requirement leading to mismatch of fertilizers, loss of resource management also higher incidence of pests and diseases. A study was undertaken to assess the nutrient variability in the farmer’s field to derive site specific recommendations for readdressing the major nutrient recommendations for improving the garden fertility status for sustainable yields. Spatial distribution of nitrogen, phosphorus and potassium were studied from 99 coconut farmers covering 195 acres of 20-25 years old representing different irrigation situations. The standard technique of grid method with a spacing of 50x50 m was employed to drawn soil samples from the selected study area in 0-30 and 30-60 cm depth with geographical identity by GPS. The standard lab techniques are used to find major nutrients in samples and mapped on GIS environment. Across all locations nitrogen status remained low, phosphorus shared medium to high status in equal proportion and top soil depth of 0-30 cm remained high status with 68 percent for potassium. Based on these site specific variations, rescheduling of major nutrients emphasized slightly higher application of nitrogen, less application of potassium with almost no perceptible change in application of phosphorus. Re-allocation of major nutrients based on site specificity in different study area encourages sustainability production.

Title: Evaluation of pre and post emergent herbicides for control of weeds in Castor (Ricinus communis L.) under rain fed conditions of central dry zone of Karnataka, India
Biography:
Kumar Naik A H is serving as an Agronomist with a research experience of five years in the area of Castor and Groundnut. He is currently working on ICAR-All India Coordinated Research Project at Hiriyur University of Agricultural and Horticultural Sciences, Shivamogga (India). He has expertise in castor and groundnut and noted for his contributions in the field of castor and released five technologies in castor and published more than 30 research papers in the research journals
Abstract:
Acquiring knowledge on weed control in castor crop is still limited, and new research into this area is necessary. A field experiment was conducted during 2012, 2013 and 2014 to find out most suitable and cost effective weed management practice for rain fed castor on the medium black soils of Central Dry Zone of Karnataka. The experiment consist of ten treatments involving two pre-emergence herbicides (trifluralin and pendimethalin) alone and in combination with hand weeding/inter-cultivation, inter-cropping of castor+groundnut (1:3 ratio), three weeding (20, 40 and 60 DAS), farmers’ practice (one weeding at 20 DAS fb two inter-cultures at 45 and 60 DAS), two post emergence herbicides (Quizalofop ethyl and fenoxaprop-p- ethyl, both at 50 g/ha at 25 DAS) and weedy check. The pooled results of three seasons revealed that pre-emergence application of pendimethalin at 1.0 kg/ha fb one inter-cultivation at 40 DAS resulted in better weed control efficiency and seed yield (1612 kg/ha) and B:C ratio (4.3) comparable to farmers’ practice (1332 kg/ha) and three weeding (1995 kg/ha). Herbicides controlled grasses gave moderate yield comparable to farmers’ fields. Weedy check reduced the yield by 76% due to severe competition offered by grasses and broad leaf weeds. The large scale demonstration on five farmers’ fields in Chitradurga district also revealed that pendimethalin at 1.0 kg/ha fb one inter-cultivation at 40 DAS (1477 kg/ha and 3.90) gave seed yield and B:C ratio comparable to farmers’ practice of weed control (1493 kg/ha and 3.70).

She has published more than 10 papers in reputed journals and has been serving as an editorial board member of reputed journals. She has a wide experience of working in nutritional quality of maize with specialization in carotenoids.
Abstract:
The present investigations were done to standardize the storage techniques for total carotenoids and B-carotene in maizes as carotenoids are subject to destruction on storage. Thirteen public and private hybrids as well as composites taken for the study were stored using different storage techniques. Total catoenoids were estimated using standard procedure whereas b-carotene which is a precursor for vitamin-A was standardized by using Ultra-Performance Liquid Chromatography on an interval of 2 months and its degradation was modelled during storage. The results showed that lyophilized seed showed minimum destruction of carotenoids and highest nutritive value and metal bin was the next strategic option to be followed to check the carotenoids destruction. In contrast, mud bin was having highest level of destruction. Carotenoids content and hence vitamin-A activity decreased markedly with time. Rate of degradation of b-carotene was less in lyophilized seeds as compared to other storage techniques. The average shelf-life at room temperature was approximately six months for total carotenoids while much less for b-carotene.

Abstract:
Maize is the third most important cereal crop of the world. Maize silk (Zea mays L.) refers to the stigmas from the female flower of the maizeand present in abundance after maize harvest. It contains carbohydrates, proteins, Ca, K, Mg, vitamins fixed and volatile oils, steroids such as sitosterol and stigmasterol, saponins, alkaloids, tannins, and flavonoids. Methanolic extract of corn silk has very high antioxidant activity. The male wistar rats were orally administered with corn silk extract and their blood glucose was significantly decreased in streptozotocin-induced hyperglycemic mice in Type-II diabetes, whereas the level of insulin secretion was increased markedly in streptozotocin-induced hyperglycemic. The streptozotocin -damaged pancreatic β-cells were partly recovered gradually after the rats were administered with maize silk extract. However, maize silk extract increased the level of hepatic glycogen in the streptozotocin-induced hyperglycemic rats; there was no significant difference in the control group. The study suggests that maize silk extract can be a potential hypoglycemic or antidiabetic agent in terms of this modern pharmacological industry and can acts as a connection between agriculture and medicine.
