Anand Agricultural University, Anand
Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur
AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

ThesisItem Open Access Direct and Residual effects of different Fe-Carriers on the performance of wheat-maize sequence(AAU, Anand, 1988) Ramani, V. P.; Dangarwala, R. T.A field experiment was conducted on a loamy sand soil to evaluate the most effective Fe-carrier on the basis of direct and residual effects of Fe application on the periodical changes in Fe status at 30, 60, 90 days after sowing and at maturity both in soils and wheat plants, their interrelationship, the yield and chemical composition of wheat, the dry matter production of maize-stover and overall realization. The experimental soil was poor in N, medium in P, adequate in K and fairly adequate in Fe contents.ThesisItem Open Access CHEMICAL COMPOSITION AND SMOKE CHARACTERISTICS OF BIDI TOBACCO AS INFLUENCED BY ZINC LEVELS(AAU, Anand, 1988) PATEL, J. S.; PATEL, B. K.With a view to finding out the influence of different levels of Zinc on the yield , quality and chemical composition as well as smoke characteristics of bidi tobacco cv GT 5 and nutrient status after the harvest of crop, an experiment was undertaken at Bidi Tobacco Research Station , Gujarat Agricultural University, Anand Campus, Anand during the year 1986-87. The experiment consisted of four levels of Zinc, namely no Zinc (Zn0), 2.5 ppm (Zn1), 5 ppm (Zn2) and 7.5 ppm (Zn3) Zn. Zinc was applied inform of Zinc sulphate. The experiment was conducted in a randomised block design with six replications . The observations on yield and its attributes, spangle score, valuation and monetary returns were recorded. The net returns were also computed. The samples of leaf lamina, midrib, stalk and suckers were analysed for various chemical constituents and uptake of major, secondary and micronutrients was worked out. Bidis prepared out of the produce from different treatments were subjected to smoke analysis. Soil samples collected upto 15 cm depth after the harvest of the crop were analysed for major and micronutrient cations. Though yield differences were non-significant due to Zn application, Zn2 (5 Ppm Zn) treatment produced highest cured leaf and fetched the highest price of its produce thereby earning maximum gross realization. Cost : benefit analysis based on the price of Zn application showed that Zn1 and Zn2 treatments were comparable. Data on the chemical composition revealed that nitrogen, nicotine and reducing sugars contents were not significantly modified by Zn application. The content and uptake of N, K, Ca, Mg and Cu as well as their total uptake remained significantly unaltered due to different treatments . Phosphorus content of lamina was significantly changed by Zn application, wherein minimum P2O5 conxent (0.65 %) was recorded at the highest (Zn,) level of applied Zn, Indicating Zn-P antagonism at the higher levels of applied Zn. Sulphur content and uptake were significantly affected by Zn application in case of midrib.In general C1, Fe and Mn contents and uptake data showed synergistic relationship with Zn application. Zinc content of all the plant parts and the total uptake of Zn showed significant differences due to Zn application. Zn content and uptake increased as the rate of its application increased. Total particulate matter (TPM), CO, and smoke nicotine were minimum and number of puffs were maximum under Zn3 treatment, which showed significant differences due to Zn application. None of the major and micronutrients except Zn were significantly changed by Zn incorporation into soil. Zn application steadily increased available Zn status of soil . Above findings suggest that Zn application in a zinc deficient (0.45 Ppm Zn) loamy sand soil of Anand requires Zn supplementation for the improvement of yield and quality. Besides this Zn application at higher rates ( 5 and 7.5 Ppm Zn) has helped in reducing smoke toxicants, which has opened up new horizons for making bidi safer smoking product. However, these findings need to be confirmed by further experimentation before making any valid recommendation.ThesisItem Open Access EFFECT OF DIFFERENT MOISTURE REGIMES, LEVELS AND SOURCES OF PHOSPHORUS AND FYM ON THE AVAILABILITY OF NUTRIENTS IN THE SOIL OF WHEAT-GROWING AREA OF BHAL (GUJARAT)(AAU, Anand, 1988) PATEL, V. S.; PATEL, J. C.A laboratory incubation study was conducted during the year 1987, to evaluate the effect of different moisture regimes viz., 40, 30, 20, 10 and 40 (rewetting) per cent simulated due to depletion in moisture from flooded soil and again rewetting in presence (13.5 t/ha)/absence of FYM and different levels of P ( 0 , 4.87 and 9.74 ppm) applied through dicalcium phosphate and diammonium phosphate on the availability pattern of P, K, Fe, Mn, Zn, Cu and the changes in soil pH in a clay loam soil of wheat-growing area (Bhal). The study revealed that the value of soil PH was increased from 7.54 to 7.57, 7.51 and 7.65 when moisture depleted from 40 (M1) to 30 (M2) 20 (M3) and 10 (M4) per cent, respectively. Application of FYM markedly decreased the soil pH from 7.73 to 7.40. The availability of P and K in the soil was decreased significantly when the moisture was depleted from 40 to 10 per cent. Again on revetting the soil , availability of nutrients was restored. Application of diammonium phosphate at higher level significantly increased the availability of P in the soil over dicalcium phosphate. Application of FYM significantly increased the available P and K contents in the soil. The contents of DTPA-extractable Pe and Mn significantly decreased with depletion in inoisttire from 40 to 10 per cent, however, the reverse was true for Zn and Gu. Again on rewetting the soil , availability of nutrients was restored. Application of P at higher level significantly decreased the availability of Fe, Zn and Gu, while reverse was true for Mn. The magnitude of adverse effect of P on the avalbility of Fe, Zn and Gu was significantly reduced when it was applied through DAP over DCP, while the availability of Mn was significantly enhanced by DAP over DCP. The availability of Fe, Mn, Zn and Cu was significantly increased due to FYM application. The results of the present investigation clearly showed that at higher moisture level, application of FYM significantly enhanced the availability of different nutrients. DAP was observed a better source in increasing the Olsen's P and maintaining the micronutrients availability as compared to DCP, The pattern of nutrient availability also remained more or less same on rewetting the treated soil.ThesisItem Open Access MINERAL UPTAKE AND YIELD OF WHEAT (Triticum aestivum L.) AS INFLUENCED BY NITROGEN, PHOSPHORUS AND ZINC FERTILIZATION(AAU, Anand, 1988) Patel, Khushvadan C.; Patel, J. C.The present investigation was carried out with a view to studying the effect of different levels of nitrogen (80, 120, 160 and 200 kg/ha), phosphorus (40, 60 and 80 kg P2O5 / ha ) and zinc (0. 5 kg/ha) on yield , content and uptake of nutrients by wheat (Sonalika) grown on goradu soil of Anand in rabi season (1986-87). Split plot design was followed for laying out the experiment. The present study revealed that application of 120 kg N/ha significantly increased the grain (10.5%) and straw (6.3%) yields over 80 kg N/ha, being at par with 160 kg N and 200 kg N per hectare in case of grain and 160 kg N/ha in case of straw. Application of phosphorus @ 60 kg P2O5/ha significantly increased the grain (4.0%) and straw (2.0%) yields over 40 kg P2O5/ha. Application of 5 kg Zn/ha (ZnSO4 ) significantly increased the grain (3.6%) and straw (2.8%) yields over no zinc. The highest straw yield was recorded under N2OOZn5. which was significantly higher over minimum yield under N80Zn0. treatment combination. Application of 120 kg N/ha significantly increased the N, S and Zn contents in grain and straw over 80 kg N/ha except Zn content of grain which was significant upto 160 kg N/ha and Zn contents of grain and straw which were significant upto 200 kg K/ha. Application of 60 kg P2O5/ha significantly enhanced the content of N and P of grain and S content of straw over 40 kg P2O5/ha. However, Fe and Zn contents of grain and straw (except Zn in grain) were significantly reduced due to 80 kg P/ha over 40 kg P2O5/ha. Application of 5 kg Zn/ha (ZnSO4) significantly increased Zn and Mn contents of grain and straw (except Mn in straw) over no zinc. However, Fe and Cu contents of grain and straw were significantly reduced due t o application of 5 kg Zn/ha. Interaction of N x Zn showed significant effect on Zn content by straw. Uptake of N, P, K, S, Pe and Zn by grain and straw as well as total removals were significantly enhanced due to application of 120 kg N/ha over 80 kg N/ha (except uptake of P by straw and total removal, uptake of Fe and Zn by grain ) . However, total Fe uptake significantly decreased at N160 over N120 level. Application of 60 kg P2O5/ha significantly enhanced the uptakes of N, P and S by grain and straw as well as total removals over 40 kg P2O5/ha (except uptakes of N and P by straw) . However, total uptake of Fe and Zn uptake by straw were significantly reduced at 80 kg P2O5/ha over 40 kg P205/ha. Uptakes of N, S, Mn and Zn by grain , straw and total removals were significantly enhanced with the application of 5 kg Zn/ha except N uptake by straw. However, uptakes of Fe and Cu by grain , straw and total removal were significantly reduced due to zinc application except Fe uptake by straw. Interaction of N x Zn showed significant effect on Zn uptake by straw. In general , it can be concluded that for getting optimum wheat yields and larger utilization of nutrients, application of 120 kg N/ha and 60 kg P2O5/ha alongwith 5 kg Zn/ha (ZnSO4) appears to be optimum dose for wheat (Sonalika) grown on goradu loamy sand soil of Anand.
