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.

    RADIATION REGIME OVER ROW ORIENTATION IN WINTER WHEAT (Triticum aestivum L.)
    (AAU, Anand, 2004) LUNAGARIYA, MANOJKUMAR MAVJIBHAI; Shekh, A. M.
    A field experiment was conducted during the rabi season of 2003-2004 at Anand. The experiment was laid out in Split Plot Design with the two dates of sowing as main plot and four treatment combinations of two row orientation and two row spacing as sub-plots, replicated four times. The objective was to study solar radiation regime with respect to the row orientation, row spacing and leaf geometrical parameters for Wheat crop (cv. GW- 496). The experiment was planned with the objectives to determine the influence of the treatments on the RUE, Extinction Coefficient (k), Direct beam radiation interception, soil surface temperature and soil moisture lost/evapotranspiration (as influenced by radiation penetration between rows). Comparison of the season encountered by the crop during the experimental period with that normally found in the region was made by comparing the seasonal values of different weather parameters with their normal for Anand. The nonsignificant differences in respect of each of the weather parameters established that the experimental season was identical to the normal one. Hence these results could be applicable to any normal wheat growing season around Anand region. The experimental findings obtained during the course of the present investigation revealed that the highest interception was recorded during the morning hours and there was negligible difference among the treatments in this respect. The difference in the interception was higher during noon time and narrow NS rows intercepted higher PAR (0.92). Wide NS rows and wide EW rows had higher solar radiation interception than that narrow EW rows at noon hours. The seasonal average of the fraction F indicated more or less identical results that representing different treatments, narrow NS oriented row had highest F value i.e.0.86 and while in narrow EW rows had the poorest value (0.77). There was low RUE in early growth stages because more solar energy was used up being incident on the soil surface rather than on the plants due to inadequate development of plant canopy. The RUE showed maximum value at booting stage. There was no significant difference in the RUE among the treatments and also among interactions. The difference in the RUE was found negligible. Slightly high RUE was found in the widely spaced EW rows during in second sowing (i.e.2.07 g MJm-2) as compared to the general mean (i.e.2.01 g MJm-2). The lowest RUE was observed in wider NW rows (i.e. 1.96 g MJm-2 and 1.97 g MJm-2 for respective sowing times). There was no statistically significant difference among HI values corresponding to different treatments revealed that there was no difference in fraction of radiant energy used for grain biomass. High averaged LAI was recorded in narrow NS rows during both sowing dates (3.26 and 3.7, in respective sowing dates). Wide NS rows (2.67 and 3.38, in respective sowing dates) succeeded this treatment. The EW rows produced lower LAI. The NS rows (narrow and wide) did not show much fluctuation in the values of k (extinction coefficient), while EW rows (narrow and wide) showed comparatively more fluctuations, indicating the changes in canopy structure. The average value of leaf orientation over the entire study indicated that leaves usually preferred N (16.6 %), S (16.1%) and W (13.2%) direction. General results showed the leaves were randomly oriented with different times. The seasonal average of direct beam interception fraction (I/I0) indicated that the in general, highest direct beam interception occurred on the first leaf and lowest on the second leaf while third leaf had intermediate direct beam interception. Maximum average interception fraction was 0.63 over the third leaf and minimum (0.22) over second leaf of the wider NS rows during second sowing. While, in case of the narrow NS rows of the first sowing, second leaf had high interception with 0.61 fraction, first leaf had value 0.24 and third leaf had fraction 0.41. Except these two. values for NS oriented treatments the leaves of the other treatments showed intermediate direct beam interception fraction ranging from 0.31 to 0.51 over the entire season. Soil surface temperature was observed to be slightly high at morning hours (1000 h) in the wider EW rows during both the sowings. Those for narrow EW rows followed these values. During noon time (1300 h), wide NS rows had higher soil surface temperature than respectively that for other treatments. In afternoon, the soil surface temperature did not show much difference among treatments. The difference in the temperature was considered as the function of the radiation penetration in the rows. Wide NS rows had higher evapotranspiration, in general after early growth period. Other treatments showed no distinct pattern in this respect. The moisture loss pattern had almost parallel trends for narrow and wide rows in particular orientation. This indicated that there was influence of spacing on evapotranspiration. The results revealed that NS rows and wider spacing had high radiation penetration.

    CROP WEATHER RELATIONSHIP OF ONION (Allium cepa L.)
    (AAU, Anand, 2001) CHAUHAN, VIKRAM SINGH; Savani, M. B.
    An experiment was conducted during the rabi season of the year 1998-99 at Anand to study the crop weather relationship of onion. The field experiment was laid out in split plot design with four replications. The treatments were three dates of transplanting, two plant spacing and three irrigation levels. Plant height, number of leaves per plant, fresh, weight of bulb, bulb diameter, total soluble solids (TSS) and bulb yield increased with earlier transplanting and bolting, doubling decreased with late transplanting and bulb dry weight was increased with late transplanting of the crop. Plant height, number of leaves, fresh weight of bulb, bulb diameter, TSS and bulb dry weight were higher with wider spacing whereas bolting, doubling and neck diameter decreased with closer spacing and bulb yield was increased with narrow spacing of the crop. Higher IW/CPE ratio increased plant height, number of leaves, fresh weight of bulb, bulb diameter, TSS bulb dry weight and bulb yield whereas lower IW/CPE ratio decreased bolting, doubling and neck diameter of the bulb. The crop required nearly 2270 GDD, 22000 PTU, 13600 HTU and 500 mm of water. Water use efficiency varied with the variation in the irrigation regimes and ranged between 30.25 Kg ha-1 mm-1 and 169.57 Kg ha-1 mm-1.

    (Anand Agricultural University, Anand, 2006) V.R.Parmar; Dr. VYAS PANDEY
    Pearl millet is an important cereal crop of rainfed area of India. The cultivar of the pearl millet crop has been found to be highly remunerative under kharif season and hence gaining popularity among the cereal - growing farmers of Gujarat state. Crops require certain cardinal levels of various factor of environment like air temperature, intensity and duration of radiation, humidity of air and soil moisture etc. for optimum physiological functioning. Since, the effects of weather on grain yield and fodder yield are complex. It will need the deeper and clear understanding of the climatic factors affecting the growth and yield of pearl millet. The field experiment during kharif season of year 2004 was laid out in a split plot design with four replications. The three dates of sowings were assigned as main plot treatment, four spacings as sub plot treatments.

    STUDY OF CROP WEATHER RELATIONSHIP IN SOYBEAN AND EVALUATION OF CROPGRO-SOYBEAN MODEL UNDER VARYING ENVIRONMENT AT ANAND
    (Anand Agricultural University, Anand, 2006) ANIL KUMAR; Dr. Vyas Pandey
    Soybean (Glycine max. [L] Mirrll.) is one of the leguminous pulse grain and oil seed crops in tropical and sub-tropical regions of India. It, being short duration and thermo-sensitive crop and its response to yield varies with variety and temperature, is successfully raised in kharif as well as in summer where adequate irrigation facilities are available. Since the effect of weather on crop yield is complex, it needs deeper and clear understanding of climatic factors affecting the growth and yield of soybean. A field experiment during the kharif season of the year 2004 was laid out in a split plot design with three dates of sowing (D1, D2 and D3) as a main plot treatment, four levels of spacing (S1, S2, S3 and S4) as sub-plot treatment with four replications. The results obtained during the course of study revealed

    SIMULATION OF kharif GROUNDNUT (Cv. ROBUT 33-1 and GG-2) YIELD USING DSSAT MODEL UNDER VARIED ENVIRONMENTAL CONDITION IN MIDDLE GUJARAT REGION
    (Anand Agricultural University, 2008) Mukesh Kumar Ujinwal; Dr. H. R. Patel
    In order to sustain the higher production and minimize the degradation of crop production by varied environmental conditions, an understanding of crop growth in relation to varying resource input and agro-environments is required for management options. Improved production technology at the farm level is the most crucial starting point for future improvement of productivity of groundnut by employing and adapting suitable crop growth simulation models. In addition to this, the use of crop growth simulation models comes handy to the government agencies, trade and industry and for planning about the distribution, storage, processing, and export/import of crop produce besides taking timely policy decisions on fixing levy prices as they provide accurate advance estimation of yields

    SPECTRAL CHARACTERISTICS OF WHEAT AS INFLUENCED BY NITROGEN STRESS AND VARIETY
    (Anand Agricultural University, Anand, 2009) DEEPTI VERMA; Dr. Vyas Pandey
    Wheat (Triticum aestivum L.) is the most important crop of India grown both in rain fed and in irrigated regions. The biotic and abiotic factors affect the growth, development and yield. The moisture and N-stress at different stages of the wheat are the main cause of lower productivity of wheat in Gujarat. Remote sensing is an effective tool to monitor and assess the crop conditions, its growth and development and thereby its yield. A field experiment was conducted during, rabi season of the year 2007-08 at Agronomy Farm, Anand Agricultural i
