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.

    INFLUENCE OF DECAPITATION AND PGR's ON GROWTH, YIELD AND QUALITY OF CLUSTER BEAN SEED (Cyamopsis tetragonoloba L. Taub.) CV. PUSA NAVBAHAR
    (AAU, Anand, 2010) NARSHI, SATODIYA BAKUL; Patel, H. C.
    A field experiment was conducted at Main Vegetable Research Station, Anand Agricultural University, Anand during the years 2008-09 and 2009-10 in summer seasons on sandy loam soil with a view to study the "Influence of decapitation and PGR's on growth, yield and quality of cluster bean seed (Cyamopsis tetragonoloba L. Taub.) cv. Pusa Navbahar" under middle Gujarat conditions. There were twenty one treatment combinations comprising three decapitation treatments i.e. D1-Without decapitation (control), D2-Decapitation at 70 DAS and Ds-Decapitation at 85 DAS and seven different PGR's treatments along with control i.e. G1 -Water spray (Control), G2-NAA 20 mg/l, G3-NAA 40 mg/l, G4-GA3 20 mg/l, G5-GA3 40 mg/l, G6-Thiourea 500 mg/l and G7-Thiourea 1000 mg/l in a Randomized Block Design (Factorial) with three replications. Growth parameters viz. plant height and number of leaves per plant were found non-significant at 30 and 60 DAS. Whereas, without decapitation (control) treatment recorded significantly the highest plant height i.e. 112.07 and 115.72 cm and number of leaves per plant i.e. 50.70 and 45.15 at 90 DAS and harvest stage, respectively. The effects of decapitation on physiological parameters viz. LA, LAI, CGR, NAR and dry weight of plant were found non-significant at 30 and 60 DAS whereas, at 90 DAS all the physiological parameters and at harvest only LA and dry weight of plant recorded significantly, higher values in control treatment (Without decapitation). Decapitation of plant at 70 DAS registered significantly the highest number of pods per cluster (7.55), number of clusters per plant (18.29), number of pods per plant (138.00) and weight of 1000 seeds (37.00 g) in pooled analysis. However, dry pod length (9.59 cm) and number of seeds per pod (7.05 cm) were found maximum in treatment decapitation at 85 DAS. Decapitation of plant at 70 DAS produced significantly the highest seed yield (917.7 kg/ha) in pooled analysis as compared to without decapitation (889.13 kg/ha), which was 9.26 % higher than without decapitation. Root and shoot ratio (0.057) and harvest index (627.04) were also found significantly superior in treatment decapitation at 70 DAS. Seed quality parameters viz. seedling length, seedling dry weight, vigour index-I and II were recorded the highest values in treatment decapitation at 70 DAS at 6th 8th and at 10th day on pooled basis. Plant growth regulators treatments significantly influenced growth parameters viz. plant height and number of leaves per plant at various growth stages of crop except at 30 DAS. At 60, 90 DAS and harvest stage treatment GA3 40 mg/l recorded significantly maximum plant height and number of leaves per plant as compared to rest of treatments. Physiological parameters viz. LA, LAI, NAR and dry weight of plant at 60 and 90 DAS registered significantly the higher values in treatment GA3 40 mg/l in pooled analysis. At harvest, LA, LAI and dry weight had recorded significantly maximum values in treatments Thiourea 500 mg/l and GA3 40 mg/l which remained at par with each other. Yield attributing characters viz. number of pods per cluster (7.25), number of clusters per plant (18.75), number of pods per plant (136.01), dry pod length (9.86 cm) and weight of 1000 seeds (37.22 g) were significantly the highest in treatment Thiourea 500 mg/l on pooled basis. The significantly maximum seed yield was recorded by the treatment Thiourea 500 mg/l (1030.36 kg/ha) in pooled analysis, which was at par with treatment GA3 20 mg/l (992.81 kg/ha) which was 26.67 and 22.05 %, higher than control, respectively. The treatment GA3 20 mg/l recorded the highest harvest index (638.80). Seed quality parameters viz. germination percentage, seedling length, seedling dry weight and vigour index-I and II were recorded the maximum values in treatments of GA3 and Thiourea at all the three stages i.e. 6th, 8th and 10thday. Interaction effects between decapitation and PGR's treatments on growth parameters viz., plant height and number of leaves per plant showed significant differences at 60, 90 DAS and harvest stage except for number of leaves per plant at harvest. Different combination of decapitation and PGR's treatments recorded significant results on physiological parameters at various growth stages viz. LA, LAI, CGR, NAR and dry weight of plant. At 60 and 90 DAS LA, LAI, NAR and dry weight of plant recorded significant results in different combinations except CGR at 60 DAS. At harvest stage, CGR, NAR and dry weight of plant were found significant due to interaction between decapitation and PGR's treatments. At all the growth stages, interaction between without decapitation and treatments of GA3 and Thiourea recorded significantly higher values of all the physiological parameters. Yield attributing parameters viz. number of seeds per pod and weight of 1000 seeds significantly affected by interaction between decapitation and PGR's treatments which, were the highest in combinations D'aGe (8.20) and D2G6 (41.40 g), respectively. Seed quality parameters like, seedling length, seedling dry weight and vigour index-I and II recorded the maximum values in combinations of decapitation at 70 DAS with treatments of GA3 and Thiourea at all the three stagesi.e. 6th 8th and10th day. The higher net return of 47,849 Rs./ha along with B.C.R. of 1: 2.60 was obtained by decapitation at 70 DAS, whereas, the lowest net realization (41,935 Rs. /ha) and B.C.R. (1:2.43) was obtained when plant decapited at 85 DAS. The treatment Thiourea 500 mg/l recorded the maximum net realization of Rs. 52,277 per hectare with 1:2.73 B.C.R., followed by treatment GA3 20 mg/l.
