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.

    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.

    SOME STUDIES ON PREDATORY SPIDERS IN HYBRID COTTON-6 AT ANAND
    (AAU, Anand, 1988) DHULIA, F. K.; YADAV, D. N.
    Studies were made on various predatory spiders associated with insect pests of hybrid cotton-6 at Anand Campus of the Gujarat Agricultural University during 1986-87. In all thirteen species of predatory spiders belonging to nine different families were recorded. These included five species of hunting spiders viz., Oxyopes ratnae, Glubiona sp., Castianeira sp., Plexippus sp. and Hippasa sp., four species of web-building spiders viz., Neoscona theisl, Neoscona sp.,. Uloborus khasiensis and Argiope pulchella, three species of ambushing spiders viz., Thomisus sp., T. cherapunjeus and T. projectus and one species of Olios sp. Hunting spiders dominated over other species and accounted for 63.15 per cent of the total population. Amongst these O. ratnae was found to be most important and predominant. Seasonal activity of O.ratnae, Glubiona sp., A. pulchella, Castianeira sp.. Olios sp., N, theisi, Thomisus sp. and U. khasiensis was also studied and were found predatory on insect pests such as Heliothis armigera Hxibner,, Spodoptera litura Fab., Anomis flava F., Earias vittella F., Dysdercus cinqulatus Fb., Aphis qos sypii Glover,, Ainrasca biguttula biguttula Ishida, and Bemisia tabaci Gennadius, Observations on biology of O. ratnae show that, the spider laid on an average 2.8 egg-raasses during her life span. The incubation period was 9-11 days (the average being 10.1 days) and numbers of spiderlings emerged per egg-mass varied from 30-42, with an average of 35.6. Male and female pass through 10 and 11 instars respectively to reach maturity. Male spiderlings took 157-215 days (the average being 187.20 days) whereas the female took 221-295 days (the average being 259.50 days) to complete the development. Total life span from the emergence of the spiderlings to the death of the adult varied from 260-349 days in case of male (The average being 305.8 days) whereas it varied from 323-418 days in case of female (The average being 358.80 days). The male and female mated readily under laboratory conditions, the mating lasted for few seconds. Mortality during different instars varied from 4,00 to 17.64 per cent, it was more in the 12 instar spiderlings (17.64%), The female spins silken cocoon before laying eggs and then covers them with silken threads. It was also found to take care of the eggs by sitting over them. Just hatched spiderlings were able to survive for 9.6 days when starved. The residual toxicity of fenvalerate (0.015%), endosulfan (0.07%), phosphamidon (0.03%) and monocrotophos (0.04%) was found to be high to the second instar spiderlings of 0. ratnae. Amongst them endosulfan was found having greater residual toxicity. Thus, fairly rich fauna of predatory spiders occurred in hybrid cotton-6. In view of their abundance, longer activity, long longevity and predation on variety of insects, it is suggested that as far as possible the spiders should be conserved by minimizing the apolication of pesticides such as fenvalerate, endosulfan, phosphamidon and monocrotophos. It would also be worthwhile attempting mass rearing of species like Oxyopec ratnae and Clubiona and utilizing them against insect pests of cotton. It would be interesting to study their occurrence on other crops, to know wheather these species show some affinity for particular habitat.
