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.

    EFFECT OF THE STUNT NEMATODE, Tylenchorhynchus vulgaris UPADHYAY et al., 1972 ON WHEAT AND ITS CONTROL
    (AAU, Anand, 1987) PATEL, PANKAJKUMAR NARANBHAI; Thakar, N. A.
    A pathogenicity study of the stunt nematode, Tylenchorhynchus vulgaris on wheat variety J-24 with different inoculum levels viz. 10, 100, 1,000 and 10,000 nematodes per plant/pot of 600 g soil keeping uninoculated control as check revealed the inoculum levels of 1,000 and above to reduce significantly the different growth attributes viz. shoot length, fresh shoot and root weights compared with control. In the growth character of root length, the inoculum level of 100 nematodes per plant was also significantly detrimental. The soil population at harvest in soil increased with increase in inoculum levels. However, the reproduction factor was found to increase with increase in initial inoculum levels up to 100 nematodes, while it was decreased with increase in initial inoculum levels of 1,000 and above nematodes per plant. Testing of four systemic granular nematicides viz, Phenarniphos Phorate, Carbofuran and Ethoprophos as soil application with their three doses of 1, 2 and 3 kg/ha against T, vulgaris on wheat variety sonalika resulted all the nematicides at their three doses to increase all the growth attributes under the study except productive tillers and reduced the nematode population significantly over control (no nematicidal treatment). Amongst 4 systemic nematicides under the study, Phorate was the raostp effective in increasing the growth characters except total and productive tillers while, ethoprophos was the least effective. The nematicides carbofuran and phenamiphos were in between these two in their effectiveness in improving the growth characters. The nematicide phenamiphos was found to be the most effective, while ethoprophos was the least effective in reducing the nematode popxilation, Nematicides phorate and carbofuran were moderately effective in reducing the nematode population. Amongst three doses tried, the growth characters of shoot weight and root weight were increased with an increase in doses from 1 to 3 kg/ha, the doses of 2 and 3 kg/ha being at par with each other. The nematode population at harvest decreased with an increase in the doses of different nematicides. Amongst twelve interactions (N x L) phenamiphos 1 & 2 kg, phorate 1, 2 & 3 kg, carbofuran 2 & 3 kg and ethoprophos @ 3 kg/ha were observed to be effective in increasing the shoot length, fresh shoot weight and fresh root weight, while the total and productive tillers were significantly not affected. Except phenamiphos, all the nematicides increased the growth characters with an increase in their doses. In case of phenamiphos, the growth characters were decreased with an increase in its doses which might be due to sane toxic effects of the same on wheat, Phenamiphos @3kg/ha was found to be the most effective in reducing the nematode population followed by phenamiphos 2 kg, phorate 3 kg and carbofuran @ 3 kg/ha. The treatments of ethoprophos 1 kg, carbofuran 1 kg, phorate 1 kg and ethoprophos @ 2 kg/ha were the least effective in nematode reduction. Testing of different organic soil amendments viz, neem cake, mustard cake, castor cake, piludi cake, karanj cake, poultry mainure, azolla dry and green and farm yard manure with urea as soil application @ 120 kg N/ha on the basis of nitrogen availability to control T. vulgaris on Wheat variety sonalika resulted green and dry azolla and mustard cake to increase different growth characters viz, shoot weight, root weight, total tillers and productive tillers significantly over control. Soil treatments with green and dry azolla were found to be the most effective in reducing the nematode population also in soil . The next most effective was mustard cake. Castor cake, Piludi cake. Poultry manure and Neem cake were the least effective, while the remaining treatments of karanj cake, farm yard manure and urea were moderately effective in reducing the nematode population.
