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.

    VARIABILITY IN BIDI TOBACCO (NICOTIANA TABACUM L.) GERMPLASM
    (AAU, Anand, 1982) PATEL, K. R.; Patel, N. M.
    Tobacco is an important cash crop of India, which occupies third position in production and second for its export in the world. Gujarat ranks second in respect of hectarege but production and productivity-wise it is at the first position in the country. In Gujarat, bidi tobacco covers more than 90 per cent of the total tobacco hectarege. The genetic variability is the prime requirement for the Improvement of any crop as its proper management can produce permanent gain in the productivity of the plant. The information on variability existing in bidi tobacco is very much lacking. The present study, therefore, was undertaken during the year 1980-81 at the Bidi Tobacco Research station, Gujarat Agricultural University, Anand Campus, Anand to (i) estimate genotypic and phenotypic variances existing among the bidi tobacco genotypes, (ii) study interrelationship between yield and yield attributes and (iii) understand the degree of diversity existing among the bidi tobacco genotypes.

    ON THE ESTIMATION OF GENE EFFECTS IN LAL CHOPADIU TOBACCO
    (AAU, Anand, 1987) Patel, R. R.; Patel, N. M.
    Tobacco, the heighest revenue earning commodity among agricultural commodities, occupies hardly 0.3 per cent of the total cropped area of the country. Gujarat ranks second in respect of tobacco hectarage but from productivity view point it is at the first position in India. Chewing tobacco (tabacum type) is grown in about 10,000 ha of Petlad, Borsad and Khambhat talukas of Kheda district of Gujarat State. Practically no information on quantitative genetic aspect is available for chopadiu tobacco grown in Gujarat. Therefore, present investigation was undertaken during the years 1983-84 and 1984-85 at Tobacco Research Station, Dharmaj to (i) study the nature of gene effects govering yield and other agro-morphological characters, (ii) to study the influence of environment on gene effects governing yield and (iii) to evaluate the selected material of each cycle.

    PREDICTION OF LEAF AREA INDEX IN COTTON HYBRID 4
    (AAU, Anand, 1987) DARJI, VIJAY B.; Patel, N. M.
    The leaf area index (LAI) is one of the important crop growth parameters influencing yield. The estimation of leaf area and there by LAI consumes lot of time and is costlier. Prediction model for LAI can help in overcoming such difficulties. Keeping this in view, the present investigation was conducted during the year 1985-86. Cotton Hybrid ^- was used for the purpose. Crop was raised as irrigated crop at the Plant Breeding Research Farm, Gujarat Agricultural University, Anand Campus, Anand to work out prediction equation for leaf area index (LAI). The leaf area and other characters were studied at nine different stages of crop growth. The results revealed that the (i) leaf area, leaf area index (LAI), leaf number, leaf weight and stem weight of Cotton Hybrid 4 increased upto 120 days of crop age and thereafter these variables showed declining trend, (ii) leaf area and LAI showed quadratic trend while number of leaves showed linear as well as quadratic trend due to the age of crop, (iii) leaf weight accounted for maximum variability of LAI (but leaf weight is a variable of destructive in nature) and (iv) prediction equation for LAI based on number of leaves and days after sowing, both being non-destructive in nature, accounted about 92 percent of the variability in LAI. The equation obtained was LAI = 0.5595 + 0.0085 NOL - 0.0098 D (R2 = 92.2 %) (Where NOL = Number of leaves and D = DAS = Days after sowing) From utility view point, this prediction model is most simple and efficient one.

    IRRIGATION BORDER EFFECT IN BIDI TOBACCO (NICOTIANA TABACUM L.)
    (AAU, Anand, 1982) PATEL, JAYANTI K.; PATEL, N. M.
    The large variation in the treatments of the adjacent plots is likely to cause inter-plot competition affecting treatment means. In case of experiments on irrigation, large border areas around not plot is required because of lateral movement of soil moisture. Inclusion of border area increases plot-size. The large sized plots increases the total experimental area and thereby the experimental error and cost of conduct of the experiment. Considering this interesting aspect in mind, an experiment was conducted during 1981-82 at the Bidi Tobacco Research Station, Gujarat Agricultural University, Anand Campus, Anand, to assess irrigation border effect on bidi tobacco (Nicotiana tabacum L.) and if it is present, then to determine number of border row(s) required around net plot eliminate irrigation border effect.

    EVALUATION OF VARIABILITY IN EXAMINATIONS OF FACULTY OF AGRICULTURE IN GUJARAT AGRICULTURAL UNIVERSITY
    (AAU, Anand, 1989) GOLAKIA, PREMJIBHAI NANUBHAI; VAISHNAV, M. R.
    The students evaluation reports for different courses taught at the colleges of Agriculture during the years 1984 to 1986 and the result notifications of eighth semester-end examination of B.Sc. (Agri.) for the years 1986 to 1988 served as the material for the study. The abstract of the general findings are as under : 1. In almost all courses the average marking in the internal evaluation was higher as compared to marks in the semester-end examination evaluation, 2. The marking in the internal evaluation for some courses for different colleges were high, in general, the overall ranking in internal and external evaluations over different courses for majority of the disciplines remained more or less consistent for all the colleges. 3. The introduction of external examiners during 1986 did not change the overall ranking of different colleges for different disciplines as compared to the single examiner semester-end evaluation during the year 1985. 4. Eventhough the differences in the average marks scored by the students at different colleges were significient in almost all course during the year 1985 and 1986, the differences in overall weighted scores obtained by the students of these colleges in the semester-end examinations were only marginal. The differences were not as large as they were in the internal evaluations. 5. The large variation in the overall weighted score in the internal evaluation had reflected on the total evaluation of different colleges. 6. It was also observed that internal evaluation in the practicals had a significant influence on the overall internal evaluation. The differences in the average weighted scores in the practicals were high for some of the courses at some of the colleges thereby resulting to higher internal evaluation. 7. The correlation coefficients between internal and external evaluations for almost all courses during the years under study were positive and highly significant.

    PLOT TECHNIQUE IN LUCERN
    (AAU, Anand, 1990) Ramani, C. V.; Patel, N. M.
    The uniformity trial on lucern (variety Anand 2) was conducted during the years 1988-89 and 1989-90 for collecting green fodder yield data to workout optimum size and shape of the experimental plot, to compare efficiency of different experimental designs and to develop statistical technique(s) for the estimation of total green fodder yield per unit area using partial harvest data. The cut-wise yield data of 1200 plots (basic units; the size of each basic unit was 1 m x 1 m i.e. 1 m length x 4 rows) and 400 plots collected during the first and second year respectively were subjected to statistical analysis. In all six cuts were obtained during both the years. The results revealed the followings. The variability as judged by coefficient of variation per unit area (C.V.%) decreased with the advancement of the crop age upto the fourth cut, thereafter it increased. The sixth cut had maximum variability. The C.V. % decreased with the increase in size of the plot. This relationship when expressed in equation form indicated that the predictability of C.V. % was high (R2 > 0.93) when the variable plot size was transformed to log scale. The rate of reduction in C.V. % was more with the increase in width of the plot (i.e. no. of rows) than that with the increase in length of the plot. Ten units size plot (1 m x 10 m) was found optimum for field experiments on lucern. The estimates of soil heterogeneity index, b', showed large variation from cut to cut in both the years indicating the need of in depth study on casual variables. For any given size of the plot, the block of size 10 plots had comparatively lower C.V. % than block of size 5 plots suggesting that the block size influences the precision of the estimate. The block, shape also influenced the precision. The Simple and Balanced lattice designs were comparatively more efficient than Randomized Block design for field experiments on lucern. Thus use of confounding concept in field experiments on lucern crop could improve the efficiency of the treatment estimates. The correlation coefficients between yield of the individual cuts and the total yield and contribution of individual cuts to the total yield were influenced by the seasonal variation. Hence use of prediction model for estimating total green fodder yield on the basis of single cut yield or total yield of two or three adjacent cuts could not be advocated. Component Sampling and Stratified random Sampling proved efficient in comparison to simple random sampling for the estimation of total green fodder yield per unit area on the basis of partial harvest data. Component Sampling was better than Stratified random sampling, while doubling sampling was not recommended for estimating total yield on the basis of partial harvests which were influenced by seasonal fluctuation. From the present investigation, following recommendations ' could be made for field experimentation/survey on lucern crop (variety Anand 2) to be studied under Middle Gujarat condition. - The net plot size for field experiments should be 10 sq.m. covering 40 rows (spaced 25 cm. apart) each of one meter length. For agronomic convenience, 20 rows each of two meters length i.e. 10 sq.m can be taken as net plot. This shape is slightly less efficient than former shape. - While planning field experiments, confounding concept should be used (wherever feasible) for improving efficiency of the treatment estimates. - Component sampling should be used for the estimation of total green fodder yield on the basis of partial harvests.
