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.

    EPIDEMIOLOGY AND MANAGEMENT OF ROOT ROT [Macrophomina phaseolina (Tassi) Goid.] OF DESI COTTON (Gossypium herbaceum L.)
    (DEPARTMENT OF PLANT PATHOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY, ANAND, 2020) Patel Sanket V.; Dr. N. M. Gohel
    Cotton is a globally important crop used for both its natural fiber and seed. Cotton, “The White Gold” or the “King of Fibers” enjoys a pre-eminent status among all cash crops in the country. In Gujarat, cotton growing areas are divided in to four well-defined zones based on agro-climatic conditions among that the desi cotton grown specifically in Wagad cotton zone, which is spread over seven lakh hectares in six districts viz., Ahmedabad, Surendranagar, Patan, Kutch, Morbi and Botad. Among the diseases of cotton, root rot caused by Macrophomina phaseolina (Tassi) Goid. is widely distributed and highly destructive right from the seedling stage or after wood formation stage of crop causing up to 90 per cent or more disease incidence infield resulting in heavy yield losses. To overcome such issues, biological control is one of the best, low-cost and ecologically sustainable methods for managing plant diseases caused by soil-borne pathogens.

    STUDIES ON WILT COMPLEX OF CHICKPEA (Cicer arietinum L.) AND ITS MANAGEMENT
    (DEPARTMENT OF PLANT PATHOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY, ANAND, 2020) Parmar Harshil V.; Dr. N. M. Gohel
    Pulses constitute an important dietary ingredient of the oriental food due to their high protein content. The importance of pulses is much more in a country like India, where the majority of the people are vegetarian. Chickpea is a major source of protein for millions of people. To meet the ever-increasing demand for this legume crop, it is essential to manage the various stresses impacting the crop yield. The crop is affected by a number of diseases of which, chickpea wilt complex is considered the most important, devastating and challenging one, being responsible for seed rot, seedling blight, root rot and mature plant wilt. The disease usually caused by two or more pathogens is referred to as multipathogenic disease or disease complex. Management of wilt complex of chickpea is difficult to achieve as the pathogens are soil-borne, surviving through resistant structure i.e. chlamydospores and sclerotia in the soil for years even in the absence of host and the crop remains susceptible throughout all the growth stages. To overcome such issues, biological control is one of the best, low-cost and ecologically sustainable methods for managing plant diseases caused by soil-borne pathogens.

    INVESTIGATIONS ON BIOEFFICACY OF Trichoderma asperellum AND Pseudomonas fluorescens IN SUPPRESSION OF BIOTIC AND ABIOTIC STRESSES IN CHICKPEA [Cicer arietinum L.] AND MUNGBEAN [Vigna radiata (L.) Wilczek]
    (DEPARTMENT OF PLANT PATHOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY, ANAND, 2019) Jaisani Pratik; Dr. N. M. Gohel
    Chickpea and mungbean accomplish protein-rich human diet for the eradication of malnutrition worldwide. However, the yield of chickpea and mungbean are greatly reduced due to various biotic and abiotic stresses. Among the biotic stress, major fungal diseases which infect the chickpea and mungbean in common are dry root rot [Macrophomina phaseolina (Tassi) Goid.] and wet root rot [Rhizoctonia solani Kuhn] causing considerable quantitative and qualitative losses. Among the different stresses, soil salinity and drought are major abiotic stresses leading to adverse effects on the phenology and physiology of the crop plants and ultimately yield losses. The usage of fungicides against plant pathogens produces a negative impact on the nodulation of legumes and adverse effects on survival of microflora within the soil as well as enhance resistance problems in pathogens. The use of antagonistic fungi and plant growth-promoting rhizobacteria has been realized due to their potentiality of competition, antibiosis and plant growth promotion. Therefore, the biocontrol efficacy of fungicide tolerant antagonists i.e. Trichoderma asperellum and Pseudomonas fluorescens on suppression of biotic and abiotic stresses were studied.

    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.
