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.

    EVALUATION OF DIFFERENT STATISTICAL MODELS FOR PRE-HARVEST FORECASTING OF PEARL MILLET (Pennisetum glacum L.) PRODUCTIVITY IN KHEDA DISTRICT OF MIDDLE GUJARAT
    (DEPARTMENT OF AGRICULTURAL STATISTICS B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2017) Satvinder Kour; Dr. P. R. Vaishnav
    A timely and reliable forecast of yield of crop needs little emphasis for monsoon dependent country like India where, the economy is mainly based on agricultural production. Weather is a major factor affecting crop production in advanced agricultural systems. The large variation in yield from year to year and place to place is dominated by the weather parameters. In view of fluctuating weather effects, a timely and reliable forecast of crop productivity could help in deciding the policies.

    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.

    A BIOMETRICAL STUDY OF GENETIC DIVERGENCE IN MACRONI WHEAT UNDER IRRIGATED CONDITIONS
    (AAU, Anand, 1984) DIXIT, S. K.; Patel, Ramjibhai M.
    The present investigation was carried out with 144 genotypes of macroni wheat under three sowing periods during Rabi 1982-83 at Gujarat Agricultural University, Junagard Campus, Junagadh. The analysis of variance revealed highly highly significant genotypic variances for all the characters in each of the three sowing periods. The highest genotypic coefficient of variation (GCV) was observed for the number of tillers per plant followed by grain yield per plant, harvest index, plant height, grain yield per spike and number of days to flowering which indicated the presence of vast genetic variability for these characters.

    ASSESSMENT OF CROP LOSS IN OKRA (ABELMOSCHUS ESCULENTUS L.) DUE TO PESTS AND DISEASES
    (AAU, Anand, 1985) PATEL, JESANGBHAI K.; Patel, Ramjibhai M.
    The field experiment was conducted to assess the losses of fruit yield of okra crop due to pests and diseases during monsoon 1984 and summer 1985 at College Agronomy Farm, B. A. College of Agriculture, Gujarat Agricultural University, Anand Campus, Anand. The results revealed that the application of F.Y.M. at the rate of 20 tonnes/ha did not influence the jassid, aphid, mite and shoot and fruit borer population compared to that without F.Y.M. during both the seasons under study. Likewise, it was not found beneficial in reducing either yellow vein mosaic disease or root-imot disease caused by nematodes in both the seasons. However, it was found beneficial in increasing total fruits amounting to 40.27 and 2.94 per cent which on weight basis worked out to 44.44 and 11.35 per cent more compared to that with out F.Y.M. in monsoon 1984 and summer 1985, respectively.

    ON COMPARISON OF PLANT BREEDING DESIGNS FOR GENETIC ANALYSIS
    (AAU, Anand, 1997) Patel, Jayantibhai Sankabhai; Patel, N. M.
    The progenies developed through North Carolina designs I, II and III in two F2 populations of crosses GT 5 X A 119 and GT 7 x A 145 of bidi tobacco alongwith the progenies developed through a 5 x 5 diallel mating design in all possible ways were used to study the genetic variances. The mean performance of the progenies of all NC designs and their selfed progenies of parent plants (F3s) were also studied. Among the progenies developed through North Carolina designs I, II and III, the progenies of NCD II recorded higher mean performance for cured leaf yield and leaf length in both the crosses, while they were superior in plant height and leaf breadth in cross 2. They also showed early flowering in both the crosses. In cross 1 progenies of NCD I showed higher mean performance for plant height and number of leaves. Higher mean performance for cured leaf yield and leaf length with early flower initiation in both the crosses and for plant height in cross 2 was observed in NCD II and III than their selfed progenies (F3). NCD I progenies were superior for plant height and number of leaves/plant in cross 1 than their F3s. Mean performance of leaf breadth was higher in all NC designs than their respective Fas in both the crosses. Additive variances for all the characters were found nonsignificant in NCD I (both the crosses) and in NCD II in cross 2. Number of leaves/plant in NCD II and days to flower in NCD III in cross 1 and cured leaf yield and plant height in both the crosses exhibited significant additive variances. Barring leaf breadth all the additive variances in diallel were significant. In cross 1 none of the dominance variances in NCD II and III was significant. In NCD I dominance variances for cured leaf yield and leaf length in both the crosses, number of leaves and leaf breadth in cross 1 and days to flower and plant height in cross 2 were significant. In cross 2 cured leaf yield in NCD II and plant height in NCD III exhibited significant dominance variance. Dominance variances for plant height, leaf length and leaf breadth were significant in diallel design. Dominance ratio were inconsistent in different NC designs within crosses barring the plant height which showed partial dominance in all NC designs. Barring the plant height in cross 1 all characters in NCD III and diallel design expressed partial dominance of genes. The highest percentage of significant additive and dominance variances were observed in diallel design and NCD I, respectively. All the additive variances were positive in NCD II and diallel design. The highest percentage of variances with SE lower than their estimates was observed in diallel and NCD I for additive and dominance variances, respectively. Significance and standard errors of both the variances and signs of additive variance were found to be dependent on the type of mating design. Considering significance, signs and SE of the estimated variances and practical application in field diallel design was found to be most suitable design for the study of genetic variances in quantitative traits.

    NORTH CAROLINA DESIGNS IN ANALYSING GENETIC VARIATION
    (AAU, Anand, 1997) SUNDAR, R. M.; PATEL, N. M.
    Information involving various experimental designs on the estimates of genetic variance on a number of populations is available in literature. Practically, no information is available on relative efficiency of various genetic experimental designs. Therefore, the present study was undertaken to study the genetic variance obtained in North Carolina designs I and II for yield and yield attributes of bidi tobacco and also to compare relative efficiency of both the designs. The present investigation was conducted at the Bidi Tobacco Research Station (BTRS), Gujarat Agricultural University, Anand during the years 1994-95 and 1995-96. Crosses using North Carolina designs I and II were made in F2 populations of GT5xA119 (cross 1) and GT7xA145 (cross 2). The field experiment was conducted in the Compact family block design with two replications. Each experimental plot had two row of ten plants each, the inter and intra row spacing being 90cm and 75cm, respectively. The characters studied were days to flower, plant height, number of leaves per plant, leaf length, leaf width, leaf thickness and cured leaf yield. On the basis of resuhs obtained through statistical analysis of North Carolina designs I and 11 on bidi tobacco, it can be generalized that gene actions differed with different characters in cross 1 of NCD I and II barring cured leaf yield which was solely governed by non-additive gene action. In case of cross 2 under both the designs, cured leaf yield was governed by additive and dominant gene actions, number of leaves by additive gene action and average leaf length by non-additive gene action. Other characters showed differential response. The comparison of designs showed preference to NCD 11 for estimating genetic variances. The present study is based on two crosses under two designs. Therefore, there is a need to confirm the results by taking large number of crosses in various crops under different environmental conditions.
