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.

    RENIFORM NEMATODE, ROTYLENCHULUS RENIFORMIS LINFORD AND OLIVEIRA, 1940 IN TOBACCO
    (AAU, Anand, 1982) Patel, Davabhai Jethabhai; Desai, M. V.
    The experiments on reniform nematode, Rotylenchulus reniformis, in bidi tobacco conducted to study the life cycle, effect of temperature and pH on hatching of eggs, nematode survival and virulence/ histopathology, effect of nematode on seed germination and seedling development, inoculum potential in relation to growth of tobacco seedlings and reaction of tobacco.varieties to nematode revealed that R. reniformis completed its life cycle from egg to egg in 27 to 32 days at 30 to 32°C on bidi tobacco variety Anand 119, The fecundity of nematode was on an average 83 eggs per egg mass and reproduction was amphimitic. Among the different temperatures (5 to 45°C with an increment of 5°C) studied, egg hatching of nematode was significantly more a t 30°C as compared to the rest, while per cent nematode survival was significantly-more at 15°C than at the remaining temperatures. But the nematode virulence on castor variety Anand 6-4 was significantly more when incubated at 5°C as compared to the remaining temperatures. As regards the different pH levels (2 to 10 with an increment of one), nematode egg hatching was significantly more at 7 pH than the remaining levels. The nematode survival was significantly more at 9 pH than the rest, while nematode virulence on castor variety Anand 6-4 was significantly more at 9 pH than the rest barring 8 pH. Histopathological studies indicated that young female penetrated the epidermal and cortical parenchyma tissues and reached the endodermal layers intracellularly through parenchyma. The orie third anterior portion of the female remained embedded in the root. Several cells of pericycle layer surrounding the head of the nematode formed giant cells. R. reniformis reduced 36,36, 57.56, 7.91, 64.32 and 23.91 per cent reduction in seed germination, green and oven dry seedlings weights as well as number of transplantable and total seedlings over sterilized soil. The nematode also retarded the nutrients uptake by tobacco seedlings to the tune of 9.83 (Nitrogen) ,1.75 (phosphorus), 5.93 (Potassium), 10.70 (Calcium) and 1-8.59 (Magnesium) per cent under infected soil. The nema population increased from the initial level of 250 to 1400 per 100 g of soil in 45 days. Among different levels of inoculum (o, 10, loo, 1,000 and 10,000 nematodes per pot), the inoculum level of 100 nematodes per pot and above reduced the green shoot weight and plant height of tobacco seedlings. The level of 10,000 nematodes per pot while being at par with the level of 1,000 nematodes per pot had significant depressing effect on green root and green as well as dry shoot weights of tobacco seedlings as compared to the rest barring the level of 100 nematodes per pot. The level of 10,000 nematodes per pot reduced significantly less plant height as compared to the rest. The soil population per pot and total number of nematodes per plant increased significantly upto 1000 nematodes per pot, thereafter, the population did not increase significantly in the level of 10,000 nematodes per pot. similarly the reproduction of R. reniformis increased with an increase in nema population upto 3,000 nematodes per pot (0 to 5.14), It was low (0.69) in the level of 10,000 nematodes per pot. Likewise nutrients uptake also decreased with an increase in nema population and inverse correlationship observed between inoculum levels and nutrients uptake was very high with the variation in coefficient from -0.865 to -0.706. Ihe reaction of tobacco varieties viz. Anand 2, Anand 119, Dharmaj Kaliu (DK), S 20, GT 4, K 49, K 20 and Kumkumathri (Bidi types), Anand 145, and 47-75 (Chewing types) and CTRI Special, 16-103 and VaSCR (VFC types) to R. reniformis revealed none to be free from R. reniformis infestation. Varieties GT 4, Anand 145 and Anand 2 were less preferred hosts while VaSCR was highly preferred by R. reniformis. The rest of the varieties were intermediate.

    ECOMOMIC THRESHOLD OF INSECTICIDAL SPRAYINGS AGAINST BOLLWORMS (Heliothis armigera (Hb.) and Earias spp.) ON HYBRID-4 COTTON AT ANAND. (Comparison of need-based and calendar-based treatments)
    (AAU, Anand, 1980) Mulchandani, Lachmandas Nassanand; Patel, H. K.
    In a split plot designed experiment carried out during the years 1977-78 and 1978-79 the three treatment levels (damage thresholds) of 10, 15 and 20 percent bollworm damage to fruiting bodies of selected size-group (from full grown squares to young bolls) were evaluated on calendar-based and need-based schedules for their effects on yield, number of undamaged bolls, bollworm damage to retained bolls and loculi, shedding of fruiting bodies, and earliness in maturity. The applications of carbaryl 0.25 percent + DDT 0.25 percent mixture at 10 and 15 percent treatment levels were found to be equally effective in giving a maximum yield of (good seed cotton) when they were continued on need basis (Average 3506 and 3117 kg/ha at 10 and 15 percent levels respectively) and weekly basis (Average 3852 and 3409 kg/ha at 10 and 15 percent levels respectively). Amongst three frequencies of application under fixed schedules, the weekly-based frequency of application was the best.

    NUTRIENT STATUS OF THE SOILS OF GUJARAT AND ITS CROP RESPONSE RELATIONSHIPS
    (AAU, Anand, 1982) PATHAK, J. H.; Patel, Ramjibhai M.
    In the present study, efforts have been made to obtain the ready picture of the overall soil fertility of the districts/talukas of Gujarat State. The results of about 3.48 lakh soil samples analysed over a course of three years (1975, 1976 and 1977) have been used to work out district/ talukawise indices for soil reaction (pH), salt content (Electric Conductivity), available N, P and K by using the method suggested by Parker et al. (1951). Soil reaction (pH) The soil reaction viewed on district basis has been found to be normal in 10 districts and alkaline in 8 districts while only one district (viz. Dangs) possessed acidic soils. When soil reaction was examined talukawise, it was found that out of 184 talukas of the State, the soils were normal in 111 (60.33%) talukas and alkaline in 72 (39.13%) talukas while only one taluka (Ahwa taluka of Dangs district) has had acidic soils.

    INFLUENCE OF DECAPITATION, PARTIAL ROOT PRUNING AND EXOGENOUS APPLICATION OF PLANT GROWTH REGULATORS ON THE GROWTH, YIELD AND QUALITY OF POTATO
    (AAU, Anand, 1980) PATEL, BABUBHAI MAGANBHAI; Majmudar, A. M.
    The response of potato var Up-to-date in respect of its growth, yield and quality was studied by altering the natural hormonal balance through pruning treatments as well as hormonal sprays. The three pruning treatments were - (A) normal plants (intact I.e. without any pruning treatment), (B) decapitated plants (pinching off of the apex of each sprout) and (C) partly root pruned plants (cutting the roots from all the four sides of the sprout at a distance of 10 cm from the main stem). The level of KIN used were 0, 15, 30 and 60 ppm; those of IAA were 50, 100 and 200 ppm and those of GA were 50, 100 and 150 ppm. Pruning treatments were given at 7-9 leaf stage, while single spray of IAA and GA was given at 10-12 leaf stage and that, a single foliar spray of KIN was superimposed (over IAA and GA) at 15-17 leaf stage.

    BLOOD SERUM PROFILE IN CALVES AND POSTPARTUM BUFFALOES (SURTI BREED) WITH ASSOCIATED PERIDATA RELATED TO REPRODUCTIVE EFFICIENCY.
    (AAU, Anand, 1982) DEVARAJ, M.; Janakiraman, K.
    The study involved calves from birth to maturity and postpartum buffaloes. The experiment on calves indicated the potentially of Surti buffalo calves - both sexes - to attain puberty and sexual maturity between 14 to 17 months of age, with sufficient body weight and growth of reproductive. In such calves 13 biochemical characteristics were studied from birth to maturity. The serum alkaline phosphatase (AKP), protein bound iodine (PBI), calcium and inorganic phosphorus showed decrease towards puberty and sexual maturity. Total cholesterol, ester cholesterol and total protein increased towards puberty and maturity. An increasing trend around maturity was shown by serum copper and iron. Serum chlorides tended to decrease towards puberal age.
