ThesisItem Open Access Content Analysis of Gram Jagat Programme Telecast by Doordarshan(Extension Education Department, N. M. College of Agriculture Gujarat Agricultural University Navsari, 1996-05) Jha, Dipeshkuamr Jitendrabhai; Patel, Ramanbhai B.Agriculture is the basis of village life in India. More than 70.00 per cent of the populat~on depend on agriculture for their livelihood. The overall development of the country wholly depends upon the development in agriculture. It plays a vital role in Indian economy, To increase the output of food production, it is necessary that farmers must use the improved techniques in agriculture. Communication media plays a pivotal role in transfer of agricultural technology to the farming community. It minimizes the gap between the invention of new agricultural technology and its diffusion among the farmers. Among the several mass communication media, due to its audiovisual nature, television is an effective mass media not only to provide agricultural information to the people, but also to provide them healthy entertainment. The message of television has universal appeal. Since 1988, Ahmedabad Doordarshan telecasts -GRAM • JAGAT' an agricultural programme from Monday to Friday between 6.30 and 6.55 p.m. with a view to make the farmers aware of the current trends in agricultural technology for their benefit.

CV. Kesar(Fruit Science Department, ASPEE College of Horticulture and Forestry Navsari Agricultural University, 2012-06) Dhirajlal, Thakar Priyesh; Shah, N. I.The present investigation entitled "Study on scion sticks storage methods on success of softwood grafting in mango (Mangifera indica L.) cv. Kesar" was carried out during August 2011 to February 2012 at Agriculture Experimental Station, Navsari Agricultural University, Paria. The investigation compn• sm• g thirty treatment combinations of three wrapping materials, two storage conditions and six storage periods was conducted in Randomized Block Design (RBD) in Factorial concept with three repetitions. Three wrapping materials were viz., Moist cotton cloth (T!), wrapping in Moist sphagnum moss (T2) , wrapping in Moist cotton cloth + Wax coating at cutting side (T3), wrapping in Moist sphagnum moss + Wax coating at cutting side (T4) , Control [without any treatment](T5); two storage conditions consisting refrigerator condition (CI) and room temperature condition (Co) and three storage periods comprising one day (PI), three days (Po), six days (P3) of scion storage after detachment from mother tree. The minimum days required to leaf emergence were recorded when softwood grafting made with scion sticks stored after wrapping in moist cotton cloth + wax coating at cutting side (T3). Consequently, the maximum growth of grafts in terms of total number of leaves, length of sprouted scion shoot, girth and maximum success and survival noted in same treatment where as leaves area and diseases incidence on scions found non-significant with respect to wrapping materials. When grafts were made with scion sticks stored at room temperature condition (Co), it took minimum days to leaf emergence and gave maximum growth of grafts in terms of total number of leaves, length of sprouted scion shoot, girth and maximum success and survival as compared to refrigerator condition (Cl) where as leaves area and diseases incide'lce on scions failed to reach the level of significance. When grafting was done with scion sticks stored for three days (Po) which took minimum days to leaf emergence and gave maximum growth of grafts in tel illS of total number of leaves, length of sprouted scion shoot, girth and maximum success and survival of grafts. It was decreased with increase in storage period where as there were non-significant difference in respect to leaf area and diseases incidence on scions.ThesisItem Open Access EVALUATION CHANGES IN MICRO WATERSHED OF NAU CAMPUS DURING LAST DECADES(NATURAL RESOURCE MANAGEMENT DEPT., ASPEE COLLEGE OF HORTICULTURE AND FORESTRY, NAVSARI AGRICULTURAL UNIVERSITY, NAVSARI, 2013-06) Sarve, Nilam V.; SHRIVASTAVA, P. K.To evaluate the changes in micro watersheds of the campus, initially, four micro watersheds that exist in the campus were demarcated and standard characterization procedure was adopted to make a comparative physiographic study and that was practically verified in the field. It was found the watershed ‘B’ has the largest area 240.8 ha, followed by watershed ‘C’ with an area of 109.25 ha. Due to large area and higher form factor of B and C; rectangular shape, there are high discharges from these two watersheds, which can be harvested and used for multipurpose uses. The Bifurcation ration varies from 1.65 to 5.3, the highest value of bifurcation ratio was 5.5, in watershed A, which suggests structural control in the area and low permeability. Watershed A and C have been affected due to land use changes either due to more building / roads or soil sodicity in the fields. This is evident on ground as most of the buildings in residential area have been constructed and also due to ingress of sea water in the northern side has made the soils saline sodic with comparatively lesser permeability. Water table measurements from different wells in the campus watersheds, during 2012-13, show that the water table A B S T R A C T varied from near soil surface, during monsoon, to more than 5 m BGL during summer. Rainfall analysis of 2012 monsoon shows that there is high intensity rains during later part of monsoon, when there is high water table, so all the rain fall went as runoff. To assess the overall changes in NAU watersheds, satellite imageries of University farm from past and present were compared. Ground truthing was done by collecting, verifying objects on fields with that of imageries and analyzing the raw data of crops, soil and water quality from different locations of watershed. The analysis shows that there is increase in infrastructure in the form of houses, roads and water bodies as compared to past images. Type of crop and soil cannot be differentiated from the available resolution of images. However, from the analyzed data on soil and water from different watersheds, the chemical constitution of soil, matches with the topographic land features. Chemical analysis of soil and water samples collected from different cropping systems within the watersheds are documented which would be of great help to assess the changes in future and plan strategies to overcome problematic situations. There is no such data base or bench mark available to gauge the present situation as far as quality of soil and water is concerned. Satellite imageries could only show the change in land use patterns. The dissertation also attempted to document the expenditure made on watershed activities in the University campus. Results indicate lot of developmental activities in NAU campus took place in watersheds in the form of water bodies, buildings and roads, after formation of separate University. Field verification proved that created water bodies, which are seen from the images, have increased the irrigation facility. It was also observed that well water from near the water bodies is being supplied for irrigation and drinking. Field observation also showed that lot of migratory birds hover around the water bodies in early morning hours and in evenings. Thus, it became evident several intangible benefits from water bodies are Bio diversity conservation, scenic beauty, human and animal’s physical and psychological health. After the formation of NAU the total expenses incurred for development of University watershed was around 46.5 lakh Rs. Major Watershed have well laid out network of drains, there are no waste lands in the watersheds, earlier waste lands were reclaimed wither by using for water conservation or growing fodder grasses, Jatropa, forest species as per the suitability of land and available water. Since the water bodies are under the control of different departments, supplementary irrigations are given from ponds for raising various crops are per the mandate of the respective departments. It was observed that water in most of the ponds get dried by the end of rabi, only two ponds receive water from canal escapes during summer season, which are effectively utilized for irrigating summer crops. In general, it is observed that for every 1 ha pond area, having a depth of 2.5 m, below ground level, it irrigates around 5 to 8 ha area annually. Based on the field observations regarding area irrigated from individual plots, PVB, NPW and B:C ratio was worked out for each pond, the results shows that all the water bodies giving tangible benefits that score more than 10 : 1 in terms of B:C ratio, thus proving the efficacy of water bodies. The highest returns are from PG hostel pond, as its water is used even during summer season, its B:C value is much higher if its benefits from increase in milk production had been considered. Evaluation showed that the developmental activities in cultivable watersheds in addition to giving high returns are permanent asset created for long term use. Further, the methodology adopted in the thesis may help the funding agencies and governments while assessing the performance of similar watershed projects in remote and inaccessible forest locations.
