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.

    RESPONSE OF DIFFERENT LEVELS OF PLANTING DISTANCE AND NITROGEN ON GROWTH AND FLOWERING OF CHINA ASTER (Callistephus chinensis L. Nees) Cv. "Kamini"
    (AAU, Anand, 2005) PATEL, KETULKUMAR KACHARABHAI; Patel, H. C.
    A field experiment was conducted at college Nursery of B.A. College of Agriculture, Anand Agricultural University, Anand during the year 2003-04 with the objects to study the response of different levels of planting distance and nitrogen on growth and flowering of China aster Cv. 'Kamini' with 9 treatment combinations in Factorial Randomized Block Design which was replicated thrice, considering three levels of planting distance (30 x 10 cm, 30 x 20 cm and 30 x 30 cm) and three levels of nitrogen (100,200 and 300 kg/ha). The wider planting distance D3 (30 x 30 cm, 1,11,111 plants/ha) exerted the greatest influence on various growth parameters such as number of branches (31.00). Further, the wider planting distance also recorded maximum fresh weight of individual flower (1.83 g), number of flowers per plant (32.48), flower diameter (4.89 cm) and length of flower stalk (27.23 cm), minimum number of days required for first flowering (95.99 days), 50 % flowering (112.62 days) and increased nitrogen content of leaf (1.98 %). However, due to low plant density the widest planting distance had produced lowest flower yield (6.82 t/ha). On the other hand, the closest planting distance D1 (30 X 10 cm, 3,33,333 plants/ha) recorded the higher value for some of growth parameter such as plant height (55.54 cm) and lower value for individual flower diameter (4.47 cm) because of high plant density but same treatment has produced the maximum flower yield of 15.00 t/ha. An application of higher dose of nitrogen (300 kg/ha) produced maximum plant height. (54.16 cm) and number of branches (30.39). Further, it also recorded the maximum fresh weight of individual flower (1.96 g). number of flowers per plant (35.19), flower yield per plant (69.77 g) and flower yield per hectare (13.08 t/ha). This treatment also recorded minimum number of days taken for first flowering (97.92 days) and 50 % flowering (111.06 days). It also increased nitrogen content of leaf (2.41 %) as compared to lower levels (100 and 200 kg/ha). The optimum dose of nitrogen (200 kg/ha) gave maximum vase life of flowers (8.00 days). The interaction effect between different levels of planting distance and nitrogen were found to be significant on weight of individual flower, number of flowers per plant, flower yield per plant and per hectare. Treatment combination D3N3 (30 x 30 cm and 300 kg N/ha) produced highest weight of individual flower (2.23 g), number of flowers per plant (40.40) and flower yield per plant (90.71 g). However, the treatment combination D1N3 (30 X 10 cm and 300 kg N/ha) produced highest flower yield per hectare (18.83 t/ha). Finally, in commercially cultivated China aster crop Cv. Kamini grown at narrow planting distance (30 x 10 cm) alongwith adequate supply of nitrogen (300 kg/ha) could be recommended for highest flower production under Gujarat conditions.

    (AAU, Anand, 2005) SOLANKI, RAKESHKUMAR DASHRATHBHAI; PATEL, H. C.
    The present investigation entitled "Effect of biofertilizers and nitrogen on growth, yield and quality of cabbage {Brassica oleracea var. capitata L.) cv. 'Golden Acre' under middle Gujarat agro-climatic conditions" was conducted during the year 2004-05 at the Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand. A field experiment was laid out in Randomized Block Design with ten treatment combinations and three replications consisting of different levels of nitrogen along with Azospirillum, Azotobacter and Azospirillum + Azotobacter. The recommended dose of N (200 kg ha-1) was taken as control. The results revealed that treatment Tg (175 kg N ha-1+ Azospirillum +Azotobacter) gave significantly the highest plant height (32.07 cm) and fresh weight of plant (1608.00 g), which was followed by treatment T, (Recommended dose of nitrogen i.e. 200kg/ha (control)). Treatment T8 (175 kg N ha-1+ Azospirillum + Azotobacter) also gave the highest number of leaves per plant (19.95) and plant spread (2260.20 cm2) and they were at par with the treatments T1 (Recommended dose of nitrogen i.e. 200 kg/ha (control)), T2 (175 kg N ha-1 + Azospirillum) T5 (175 kg N ha-1 + Azotobcter) and treatment T9 (150 kg N ha-1 Azospirillum +Azotobacter). However, dry weight of plant was found to be non-significant. Treatment T8 (175 kg N ha-1+ Azospirillum +Azotobacter) recorded the highest average weight of cabbage head (1321.88 g), diameter of cabbage head (15.50 cm), volume of cabbage head (1293.65 cm3), yield per net plot (22.29 kg), yield per hectare (364.10 q) and minimum days to 50% head formation (43.33), and it was at par with treatment T1 (Recommended dose of nitrogen i.e. 200 kg/ha (control)). In quality aspects, head compactness (86.06 %) was significantly influenced by Treatment T8 (175 kg N ha-1+ Azospirillum +Azotobacter) but it was at par with treatment T1 (Recommended dose of nitrogen i.e. 200 kg/ha (control)). However, moisture percent in cabbage head was found to be non-significant. Looking to the economics of various treatments, it is revealed that treatment T8 (175 kg N ha-1+ Azospirillum +Azotobacter) recorded the highest net realization (Rs.62, 195 ha-1) as well as highest cost benefit ratio (1:3.15) and it was followed by treatment T1 (Recommended dose of nitrogen i.e. 200 kg/ha (control)) i.e.1: 2.90. In nutshell, it can be concluded from the present study that the treatment T8 (175 kg N ha-1+ Azospirillum +Azotobacter) recorded the highest values in growth, yield and quality attributes. Though, treatment T8 (175 kg N ha-1+ Azospirillum +Azotobacter) recorded higher values in all the characters, which was at par with T1 (Recommended dose of nitrogen i.e. 200 kg/ha (control)). Thus, it would be appropriate to use treatment T8 (175 kg N ha-1+ Azospirillum +Azotobacter) for potential yield and better quality of cabbage cv. 'Golden acre' as it reduces the use of nitrogen 25 per cent by using biofertilizers without adversely affecting on growth, yield and quality parameters as well as economic return.

Taub) cv. Pusa Navbahar" with ten treatments in a Randomized Block Design, which are replicated three rimes. The results indicated that the growth and yield parameters were significantly affected by different biofertilizers and chemical fertilizers. The treatment T9 (25 kg N/ha + 50 kg P2O5/ha + Rhizobium + PSB inoculation) recorded significantly the highest plant height (56.48 cm), (151.85 cm) at 50 % flowering and at harvest, respectively. The treatment T9 had also recorded highest RGR i.e. 0.06 and 0.04 g/g/day) at 45 DAS and 75 DAS, respectively. Different yield parameters vi%., emergence of first flower, days to 50 % flowering per plot, green pod yield per plant, per net plot and per hectare were found to be significant with different combinations of bio fertilizers and chemical fertilizers. The treatment T9 (25 kg N/ha + 50 kg P2O5/ha Rhizobium + PSB) recorded the minimum days for emergence of first flower (30.33 days), which was found at par with treatments T3 and T6. Further this treatment had also recorded minimum days taken for 50 % flowering (38.00 days) followed by treatment T3. The significantly maximum no. of pods per cluster (11.04), maximum no. of clusters per plant (19.72) was also recorded under treatment T9 which was followed by treatments T3, T8, T6 and T2 respectively. Further maximum pod length (13.03 cm) was obtained under T9, which was followed by treatment T3. The green pod yield per plant (396.00 g) per net plot (9.05 kg) and per hectare (22.88 t) were found significantly maximum under the treatment T8 which was followed by T3, T6 and T8, respectively. The maximum net realization of Rs. 51291 per hectare was recorded with the treatment. T9 (25 kg N/ha + 50 kg P2O5/ha + Rhizobium + PSB) with highest C.B.R. (1 : 2.28) as compared to rest of the treatments. Results obtained from this investigation, it is reveled that the seeds of cluster bean should be inoculated with Rhizobium and Phosphorus Solubilizing Bacteria (PSB) along with the application of 25 kg N ha-1 and 50 kg P2O5 ha-1 for getting maximum green pod yield and net profit for vegetable purpose cluster bean under middle Gujarat agro-climatic condition.

    (AAU, Anand, 2005) PALIWAL, TRIPTI; PATEL, H. C.
    A field experiment was carried out at the College Nursery, B. A. College of Agriculture, Anand Agricultural University, Anand during Kharif to Rabi season of the year 2004-05 to study the "Effect of GA3 on growth, flowering, yield and vase life of chrysanthemum (Chrysanthemum morifolium Ramat) cultivars". Nine treatment combinations comprised of three cultivars of chrysanthemum (V1: 'IIHR-6', V2: 'Shyamal' and V3: 'Sharad Mala') and three levels of gibberellic acid (G0: Control, G1: 75 ppm GA3 and G2: 150 ppm GA3) were tried in Randomized Block Design with factorial concept and replicated three times. The results revealed that among the three cultivars, the cultivar 'IIHR-6' was the tallest (68.08 cm at 90 DAT) and gave maximum number of suckers per plant (18.47), whereas maximum number of branches per plant (18.83 at 90 DAT) was observed in the cultivar 'Sharad Mala' and maximum plant spread (37.88 and 36.79 cm in N-S and E-W directions) was achieved by the cultivar 'Shyamal'. The cultivar 'Sharad Mala' was early cultivar which required minimum days to flower bud appearance (46.96 days), to first flowering (88.20 days) and for full blooming (114.86 days) after transplanting, while the cultivar 'IIHR-6' was right time flowering cultivar and the cultivar 'Shyamal' was late cultivar. The duration of flowering was also found maximum in the cultivar 'Sharad Mala' (67.04 days). Number of flowers per plant (104.65) flower yield per plant (119.80 g) and flower yield per hectare (12.64 t) were found maximum in the cultivar 'Sharad Mala' and minimum in the cultivar 'Shyamal' i.e., 30.03 flowers per plant, 91.28 g flower yield per plant and 10.01 t flower yield per hectare. Flower quality parameters like, flower diameter (6.89 cm) and individual flower weight (3.05 g) were found maximum in the cultivar 'IIHR-6', while maximum length of flower stalk (14.42 cm) was found in the cultivar 'Shyamal'. Shelf life of flowers without pedicel was found maximum in the cultivar 'Sharad Mala' (8.36 days), whereas shelf life of flowers with pedicel (9.96 days) and vase life of flowers (12.29 days) were found maximum in the cultivar 'Shyamal'. Looking to the economics of the three different cultivars, the cultivar 'Sharad Mala' recorded maximum net realization (Rs. 73,088 ha-1) with the highest C. B. R. (1:2.37) followed by the cultivar 'IIHR-6' with net realization (Rs. 65,888 ha-1) and C.B.R. (1:2.24). The results revealed that the treatment G2 (150 ppm GA3) produced significantly maximum plant height (65.71 cm at 90 DAT), number of branches per plant (16.78 at 90 DAT), plant spread (34.43 and 33.39 cm in N-S and E-W directions) and number of suckers per plant (18.98) in chrysanthemum. The plants under the treatment G2 (150 ppm GA3) required significantly minimum days for flower bud appearance (60.16 days), for first flowering (96.57 days) and for full blooming (115.49 days) after transplanting. Maximum duration of flowering (67.29 days) was also recorded under the treatment G2 (150 ppm GA3). The treatment G2 (150 ppm GA3) produced significantly maximum number of flowers per plant (67.55) and flower yield per plant (119.80 g). Maximum flower yield per hectare (12.77 t/ha) was obtained under the treatment G2 (150 ppm GA3), which was found at par with the treatment G1 (75 ppm GA3). The treatment G2 (150 ppm GA3) also recorded maximum flower diameter (6.35 cm) as well as length of flower stalk (13.39 cm) which was found at par with the treatment G1 (75 ppm GA3), while individual flower weight was found maximum (2.63 g) under the treatment G1 (75 ppm GA3) which was found at par with the treatment G2 (150 ppm GA3). The treatment G2 (150 ppm GA3) produced flowers with maximum shelf life without pedicel (8.22 days), shelf life with pedicel (10.53 days) and vase life (12.90 days). The treatment G2 (150 ppm GA3) also recorded the highest net realization (70,821 Rs./ha) as well as the highest C. B. R (1:2.25). The interactions between the different cultivars of chrysanthemum and various levels of GA3 were found significant for the number of branches per plant at 90 DAT and the individual flower weight. Results revealed that the treatment combination V3G2 (Cultivar 'Sharad Mala' with 150 ppm GA3) produced significantly higher number of branches per plant (24.60 at 90 DAT) as compared to rest of the treatment combinations. While the treatment combination V1G1 (Cultivar 'IIHR-6' with 75 ppm GA3) gave the highest individual flower weight (3.39 g), which was found at par with the treatment combinations V1G2 (Cultivar 'IIHR-6' with 150 ppm GA3) which gave 3.15 g individual flower weight and V2G1 (Cultivar 'Shayamal' with 75 ppm GA3) which gave 3.13 g individual flower weight and significantly superior over rest of the treatment combinations.

    The present investigation entitled "Effect of biofertilizers and chemical fertilizer on growth, yield and quality of chilli (Capsicum annuum L.) cv. 'S-49' under Central Gujarat agro-climatic condition" was conducted during Kharif 2004-05 at the Horticultural Research Farm of Horticulture Department, B. A. College of Agriculture, Anand Agricultural University, Anand. A field experiment was laid out in Randomized Block Design with eleven treatment combinations and three replications consisting of different levels of nitrogen and phosphorus along with Azospirillum, VAM and Azospirillum + VAM. The result revealed that treatment T8 (75 kg N ha-1 + 37.5 kg P2O5 ha-1 + Azospirillum + VAM) produced significantly maximum number of branches plant-1 and plant height, which is followed by treatment T2 (75 kg N ha-1 + 50 kg P2O5 ha-1 + Azospirillum) and treatment T5 (100 kg N ha-1 + 37.5 kg P2O5 ha-1 + VAM) in number of branches at 2nd and 4th picking. While in case of plant height treatment T8 was at par with T2, T5, and T1 (100 kg N ha-1 + 50 kg P2O5 ha-1). It was also observed that treatment T8 registered minimum days taken for 50 per cent flowering, maximum yield per plant, yield per plot, yield per hectare, which is followed by treatment T2 and T5. Further, the maximum total numbers of fruit per plant was obtained under T8, which was followed by treatment T2 and T9 (50 kg N ha-1 + 25 kg P2O5 ha-1 ' + Azospirillum + VAM). The maximum fruit length and girth was observed under the treatment T8, which is followed by treatment T2 for length of fruit at 2nd and 4th picking and for fruit girth T2, T5 and T1, was at par at 2nd and 4th picking. However, initialplant stand at the time of 50 per cent flowering and final plant stand at harvest were found to be non significant. Looking to the finit quality aspects the highest TSS, capsaicin and acidity were recorded in treatment T8 followed by treatments T2, T9, T1, and T3 (50 kg N ha-1 + 50 kg P2O5 ha-1 + Azospirillum) for TSS, T2, T9 and T1 for capsaicin content and T2, T9, and T5 for acidity. as, moisture percentage which was found to be non significant. The economics of the various treatment combinations revealed that treatment T8 recorded the highest net realization as well as the highest cost benefit ratio as compared to rest of treatments. From the forgoing results, it can be concluded that, the seedlings should be inoculated with Azospirillum and soil application of VAM along with the application of 75 kg N ha-1, 37.5 kg P2O5 ha-1 gave the superior vegetative growth, higher fruit yield with good quality and net profit for vegetable purpose chilli under Central Gujarat agro-climatic condition.

    (AAU, Anand, 2005) PATEL, CHIRAG GIRISHBHAI; JOSHI, K. I.
    The present investigation entitled "Efficacy of biofertilizers and nitrogenous fertilizer on growth, yield and quality of tomato (Lycopersicon esculentum Mill.) cv. 'Gujarat Tomato-1' in Central Gujarat Agro-climatic condition" was conducted during rabi 2003 - 2004 at the Horticultural Farm of B. A. College of Agriculture, Anand Agricultural University, Anand. Field experiment was laid out in Randomized Block Design with 10 treatment combination and three replications consisting of three levels of nitrogen i.e. 25 kg N ha-1, 50 kg N ha-1 and 75 kg N ha-1 along with Azospirillum, Azotobacter and Azospirillum + Azotobacter. The results revealed that treatment T10 (75 kg N ha-1 + Azospirillum + Azotobacter) produced significantly maximum plant height and number of branches plant-1' followed by treatment T9 (50 kg N ha-1 + Azospirill um + Azotobacter). It was also observed that treatment T10 (75 kg N ha-1 + Azospirillum + Azotobacter) registered significantly the highest length and girth of fruits, average fruit weight, fruit yield plot-1 and fruit yield hectare-1 followed by treatment T9 (50 kg N ha-1 + Azospirillum + Azotobacter) while number of fruits plant-1 was at par with treatments T9 (50 kg N ha-1 + Azospirillum + Azotobacter), T6 (50 kg N ha-1 + Azotobacter), T7 (75 kg N ha-1 + Azotobacter), T4 (75 kg N ha-1 + Azospirillum), T3 (50 kg N ha-1 + Azospirillum) and Tg (25 kg N ha-1 + Azospirillum + Azotobacter). However, days taken to 50 percent flowering and days taken for first picking were found to be non - significant but there was a positive trend observed. Quality aspects like,pulp / juice ratio and ascorbic acid content were significantly influenced by treatment T10 (75 kg N ha-1 + Azospirillum + Azotobacter) followed by treatment T9 (50 kg N ha-1 + Azospirillum + Azotobacter) except TSS which was found to be non - significant. Looking to the economics of various treatments revealed that treatment T10 (75 kg N ha-1 + Azospirillum + Azotobacter) recorded the highest net realization as well as highest cost benefit ratio and it was closely followed by treatment T9 (50 kg N ha-1 + Azospirillum + Azotobacter). In nutshell, it can be concluded from the present study that treatment T10 (75 kg N ha-1 + Azospirillum + Azotobacter) recorded highest values in terms of growth, yield and quality attributes. However, performance of all the highest values in treatment T10 (75 kg N ha-1 + Azospirillum + Azotobacter) was at par with treatment T9 (50 kg N ha-1 + Azospirillum + Azotobacter) which is significantly superior over control i.e. treatment T1 (75 kg N ha-1 alone). Thus, it would be appropriate to use treatment T9 (50 kg N ha-1 + Azospirillum + Azotobacter) for potential yield and better quality of tomato cv. 'GT-l' as it reduces the use of chemical nitrogenous fertilizer by 33.33 % using microbial inoculants without affecting growth, yield and quality parameters.

    Variability and Stability in Senna (Cassia angustifolia Vahl.)
    (Anand Agricultural University, Anand, 2005) P.N.Pandya; Dr. R.A.Khimani
    Senna (Cassia angustifolia Vahl.) is a well known purgative in Ayurvedic and Unani system of medicine and has been included in Indian, British and many other pharmacopoeias of the world. Senna is native to Saudi Arabia. However, it has been cultivated as a seasonal crop in Tinnevelly and Ramnathpuram districts of Tamil Nadu and hence known in the trade as ‘Tinnevelly Senna’. It has established its own position in the international market. The leaves and pods are the economic parts containing sennosides; which are responsible for the laxative properties. As the work on genetic parameter is scarce in literature, the present investigation was undertaken to generate information on genetic variability and stability in Senna
