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.

ThesisItem Open Access SOLAR RADIATION, PHOTOSYNTHETICALLY ACTIVE RADIATION AND THERMAL TIME RELATIONSHIP WITH CROP GROWTH IN SUMMER GROUNDNUT (Arachis hypogaea L.)(AAU, Anand, 1989) GAJJAR, R. B.; Shekh, A. M.A field experiment with two dates of sowing (D1-2nd January and D2 - 5th February), two varieties (V1- Robut 3 and V2- GAUG-2) and three irrigation levels (I1- irrigatic at 10 days interval, I2-irrigation at 15 days interval a I3-when Tc-Ta = ± 0.5°C) was conducted during the summer season of the year 1989 with objectives of (i) determining the relationship between solar radiation, PAR, LAI, DM and days after sowing in groundnut crop, (ii) relating the PAR attenuation to dry matter production and (iii) studying tin phenological behaviour and thermal requirement of groundnu cultivars with two dates of sowing. The study revealed that pod yields and fodder yield were at par with plots irrigated at 10 days interval and when Tc-Ta = ± 0.5°C. Both the cultivars yielded higher po yield when planted on 5th February. However, cv. Robut 33- had higher pod yield than GAUG-2.LAI and DM increased wit days after sowing at a linear rate^ The mean air temperature of 25.5°C during the flowering initiation in both the cultivars during both the plantings seems to have favoured higher pod and fodder yleids. Flowering began from 4 to 5 weeks after planting. Nine to ten hours of photoperiod at the time of peg Initiation was observed for both planting dates of cultlvars.ThesisItem Open Access SOLAR RADIATION, PAR AND PHOTOSYNTHETIC EFFICIENCY IN RELATION TO GORWTH AND YIELD OF PIGEONPEA (Cajanus cajan [L.] Millsp.) BASED DIFFERENT INTERCROPS WITH DIFFERENT LEVELS OF FERTILIZER(AAU, Anand, 1989) PATEL, H. R.; Mehta, A. N.A field experiment with twenty eight different treatments was conducted in collaboration with Agronomy Department at Anand during the kharif season of the year 1987-88 with the broad-based objectives of evaluating the role of intercepted PAR in the most suitable companion intercrop, assessment of economics of fertilizer use under different intercropping systems and to determine growth, light use efficiency, attenuation of PAR and yield stability of different intercrops in pigeonpea based intercropping system in Middle Gujarat conditions. The statistical analysis on the data of grain yield of pigeonpea and pigeonpea equivalent revealed that different cropping systems had significant effect on grain yield. Intercropping with soybean, groundnut, cowpea, blackgram and greengram did affect pigeonpea yield in comparison to solid stand of pigeonpea, while pearlmillet competed with pigeonpea owing to being a C-4 type and reduced the pigeonpea grain yield. Pigeonpea equivalent grain yield analysis also revealed that pearlmillet, groundnut, cowpea, greengram, soybean and blackgram intercrops appears to be most remunerative with pigeonpea. For yield stability of both the component crops in terms of grain yield, the order of intercrops viz., pigeonpea + groundnut, pigeonpea + cowpea, pigeonpea + greengram and pigeonpea + blackgram is preferred, while for in terms of gross return (Rs/ha ), the same 6rder is found suitable for intercropping. In a solid stand of pigeonpea, due to absence of companion crop, LAI peak occurred earlier (85 DAS). But for intercropped pigeonpea, LAI peak attained in latter part of reproductive stage and seems to have resulted higher rate of assimilates and partitioned for higher pigeonpea grain yield except for pigeonpea + pearlmillet cropping system. Different cropping systems, growing periods and their interaction had a significant effect on absorption coefficient of PAR light interception for pigeonpea. Per cent interception dropped after 155 DAS for pigeonpea sole, while except pigeonpea + pearlmillet rest of the cropping systems achieved higher per cent PAR interception during reproductive stage and benefited for partitioning higher grain formation for intercropped pigeonpea. The periodic photosynthetic conversion efficiency (DM produced per unit of intercepted PAR (kg ha-1 /MJM-2 ) for intercropped pigeonpea observed more or less suppressed in early stage and after harvest of intercrop, the conversion efficiency of intercropped pigeonpea was highly accelerated with canopy development which seems to have contributed for partitioning higher grain formation compared to sole stand of pigeonpea, except pigeonpea + pearlmillet system. The conversion efficiency of sole pigeonpea, during reproductive stage remained more or less constant, resulted in highest straw and lower grain formation. Looking to the overall conversion efficiency of both the component crops, except pigeonpea + pearlmillet and pigeonpea + soybean, rest of the cropping systems found superior.ThesisItem Open Access ASSESSMENT OF CROP WATER STRESS IN WHEAT AND ITS RELATIONSHIP TO YIELD(AAU, Anand, 1986) SAILAJA, DEVI. T; Mehta, A. N.A field experiment with six different irrigation treatments was conducted during the rabi season of the year 1985-86 with the broad-based objectives of evaluating the foasibility of using canopy temperature as an indicator of crop water stress of wheat experiencing different stressed conditions by studying the relationship between canopy temperature and evapotranspiration and comparing the performance of the stress indices namely “Stress Degree Day (SDD) and Crop Water Stress Index (CWSI)” in relation to the yield of wheat in Anand conditions.ThesisItem Open Access STUDIES ON SOME ASPECTS OF PHYTO ETEOROLOGY OF WHEAT (Triticum aestivum L.) AT ANAND(AAU, Anand, 1985) SAVANI, M. B.; MISTRY, P. D.The changeability of meterological factors in time and space is diverse. The most important weather variables which have to be considered as limiting plant growth and development are temperature, moisture and light (or solar radiation). The distribution of these meteorological parameters during the growing season of the crop shows great variation in the different locations of the same region and consequently, a great variability in the crop production.ThesisItem Open Access ASSESSMENT OF GROWTH AND YIELD OF MUSTARD (Brassica Juncea (L.) Czern & Coss) IN RELATION TO HEAT UNITS(AAU, Anand, 1985) PATEL, JASHUBHAI G.; Mehta, A. N.A study was undertaken to re-examine experiments already carried out at three different research stations of Gujarat Agricultural University viz., Anand (1976-77), Jagudan (1977-78) and Gardar Krushinagar (1979-80 and 1980-81) in Randomized block design, with a broad-based objective of ascertaining meteorologically the appropriate sowing date for mustard (Varuna) for the region and also to predict crop yield in relation to meteorological parameters. The treatments were different dates of sowing viz., October 10, October 25, November 9, November 24, December 9 and December 24 at Anand, October 15, October 25, November 4, November 14 and November 24 at Jagudan and October 5, October 15, October 25, November 4, November 14 and November 24 at Sardar Krushinagar.The optimum yield in kilograms per hectare were obtained for October 25 date of sowing at all the research stations.ThesisItem Open Access STUDIES ON THE ASSESSMENT OF THE PERFORMANCE OF SOME CROP-WEATHER MODELS UNDER ANAND CONDITIONS(AAU, Anand, 1985) SHEKH, A. M.; MISTRY, P. D.Crop yield forecasting is quite important to monitor the economy of any country which is predominantly agricultural. Crop-weather Hodles are formulations which mathematically relate the crop yield with the agrometeorological parameters like evapotranspiration or crop transpiration (Tc). Very little information is available on the performance of available crop-weather models under the Indian conditions. With this background, a study was planned and conducted to test and validate the performance of different crop-weather models, during the rabi season of the years 1981-82, 1982-83 and 1983-84 with Sonalika (HDM-1553) variety of wheat. The evapotranspiration (ET) losses were measured by gravimetric soil moisture measurements which were termed actual evapotranspiration (AET) and were also estimated by Priestley-Taylor (1972) approach for obtaining potential evapotranspiration (PET).ThesisItem Open Access EVAPOTRANSPIRATION STUDIES ON A BIDI TOBACCO (Nicotiana tabaccum L.) FIELD AT ANAND(AAU, Anand, 1984) BADAWE, SATISH C.; MISTRY, P. D.A field experiment was conducted over the bidi tobacco crop for the two growing seaaons in the years 1980-81 and 1981-82 for studying the water utilisation pattern of crop, ascertaining use of lysimetears in respect of their utility in crop water use studies and a comparative the study of the ET losses measured by gravimetric soil moisture measurements (ETG), the lysimetric ET losses (ETL) and the estimated ones by using the modified Penman approach (Doorenbos and Pruitt, 1975) (ETp). The studies on water utilization patterns of the bidi tobacoo crop indicated that in both the years of study the per day losses of water reduced from the initial rates, for a short period and then shooted to the highest ET rate which occurred at the period when the crop had reached the topping phase. Later on the ET rates fell and subsequently declined upto the end of the seasons.ThesisItem Open Access ASSESSMENT OF YIELD OF PIGEONPEA (Cajanus cajan (L.) Millsp.) IN RELATION TO HEAT UNITS(AAU, Anand, 1989) NIHALANI, ASHOK L.; Mehta, A. N.A study was undertaken to re-examine experiments already carried out in kharif seasons at three different research stations of Gujarat Agricultural University viz., Navsari, Bharuch and Vadodara with a broad based objective of ascertaining meteorologically the appropriate sowing date for the region and also to predict crop yield in relation to meteorological parameters. The study revealed that the total growing days (GDD) and energy degree units (EDU) were found to decrease as the sowing date was delayed. Moreover the crop yields were also found to decrease as the GDD and EDU decreased with the delay of the sowing date at all the locations. This type of trend was also found in the phases viz., secondary branches to flower bud initiation (III), flower bud initiation to 50 per cent flowering (IV) and 50 per cent flowering to 50 per cent podding (V), respectively. The significant correlations between heat indices and crop yield were obtained in the phases III, IV and V which cover the entire flowering period of the crop for Navsari and Vadodara. No significance was found for Bharuch location.ThesisItem Open Access STUDIES ON WATER BALANCE AND ITS SIGNIFICANCE IN AGRICULTURE IN YEMEN ARAB REPUBLIC(AAU, Anand, 1985) SAEED, ABKER N.; MISTRY, P. D.An attempt has been made through the agroclimatic approach (water balance technique) to know the soil moisture status of various regions of the Yemen Arab Republic to provide basis for crop planning in different seasons and areas under the rainfed conditions of the country. The monthly and yearly water balances were worked out according to Thornthwaite (1955) procedure for 10 stations viz., Alzohra, Amran, Dhamar, Gumesha, Hodeidah, Marib, Mokha, Sana’s, Tais and Wadi Zabid for a period ranging from 2 years to 12 years. Also weekly water balances were worked out for 3 stations viz., Hodeidah, Sana’s and Tais for a period ranging from 3 years to 5 years.
