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 INFLUENCE OF LEVELS OF NITROGEN, PHOSPHORUS AND BIOFERTILIZER ON GROWTH, YIELD ATTRIBUTES, YIELD AND QUALITY OF RABI GREENGRAM (Vigna radiata L.) AND ITS RESIDUAL EFFECT ON SUCCEEDING SUMMER MAIZE (Zea mays L.) UNDER MIDDLE GUJARAT CONDITIONS(AAU, Anand, 2016) ANIKET ARVIND UMALE; Dr. N. P. Chauhan; Varanasi, UshabalaA field experiment was conducted at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat during rabi and summer seasons of the years 2013-14 and 2014-15 to study the “Influence of levels of nitrogen, phosphorus and biofertilizer on growth, yield attributes, yield and quality of rabi greengram (Vigna radiata L.) and its residual effect on succeeding summer maize (Zea mays L.) under middle Gujarat conditions”. The soil of the experimental field was loamy sand in texture (locally known as Goradu soil) having good drainage with pH 7.85. The soil was low in available nitrogen, medium in available phosphorous and high in available potash. The experiment consisting of eighteen treatment combinations comprising of three nitrogen levels such as N1: 10 kg Abstract ii N/ha, N2: 20 kg N/ha and N3: 30 kg N/ha, three phosphorus levels such as P1: 20 kg P2O5/ha, P2: 30 kg P2O5/ha and P3: 40 kg P2O5/ha and two biofertilizer levels such as B0: control and B1: Rhizobium + PSB were tested under Factorial Randomized Block Design (FRBD) with four replications. All the recommended agronomic practices were followed for raising the crop during both the years of experimentation. The results revealed that the different levels of nitrogen did not exert their significant influence on plant population at 25 DAS and at harvest. Significantly higher plant height at 30 DAS (21.89 cm), 60 DAS (41.91 cm) and at harvest (51.25 cm), number of branches per plant (4.73) and dry weight of root nodules per plant (26.82 mg) were recorded under treatment N3 (30 kg N/ha) and it was remained at par with treatment N2 (20 kg N/ha). Application of nitrogen @ 30 kg/ha (N3) produced significantly higher number of pods per plant (32.94) and test weight (44.28 g) and remained at par with level N2 (20 kg N/ha). Different levels of nitrogen did not exert their significant influence on number of seeds per pod and pod length. Among the different levels of nitrogen, treatment N3 (30 kg N/ha) produced significantly higher seed (1219 kg/ha) and haulm (2823 kg/ha) yields and it were remain at par with treatment N2 (20 kg N/ha). Different levels of nitrogen did not exert their significant influence on harvest index. Abstract iii Significantly maximum protein content (23.16%), nitrogen and phosphorus content in seed and haulm as well as uptake by seed and haulm were observed under the treatment N3 (30 kg N/ha) over the rest of nitrogen levels. The highest available nitrogen in soil was observed under the treatment N3 (30 kg N/ha) (248.62 kg/ha) than N2 (20 kg N/ha) and N1 (10 kg N/ha). Available phosphorus in soil after harvest of greengram was not influenced significantly due to different levels of nitrogen. Plant population recorded at 25 DAS and at harvest were non-significant due to levels of phosphorus. Results revealed that different levels of phosphorus did not show significant variation on plant height measured at 30 DAS, but significantly higher plant height [at 60 DAS (41.77 cm) and harvest (51.48 cm)], number of branches per plant (4.71) and it was remained at par with P2 (30 kg P2O5/ha). Significantly the highest dry weight of root nodules per plant (27.12 mg) were recorded under treatment P3 (40 kg P2O5/ha). Significantly the highest number of pods per plant (33.53) and significantly higher test weight (44.36 g) were recorded under treatment P3 (40 kg P2O5/ha), remained at par with P2 (30 kg P2O5/ha). Different levels of phosphorus did not exert their significant influence on number of seeds per pod and pod length. Application of treatment P3 (40 kg P2O5/ha) recorded significantly the highest seed (1240 kg/ha) and haulm (2863 kg/ha) Abstract iv yields in pooled result. Different levels of phosphorus did not exert their significant influence on harvest index. Pooled results revealed that treatment P3 (40 kg P2O5/ha) recorded significantly the highest protein content (22.56%), nitrogen and phosphorus content in seed and haulm. Same results were observed with respect to nitrogen and phosphorus uptake by seed and haulm. Significantly the highest values with respect to available phosphorus (32.76 kg/ha) in soil was found under the treatment P3 (40 kg P2O5/ha) as compared to lower levels. But, different levels of phosphorus did not show significant variation on available nitrogen in soil. The results indicated that effects of different levels of biofertilizer on plant population recorded at 25 DAS and at harvest were non-significant during both years and in pooled result. Results revealed that biofertilizer did not show significant influence on plant height measured at 30 DAS, but significantly the highest plant height at 60 DAS (41.53 cm) and at harvest (50.82 cm) were observed under treatment B1 (Rhizobium + PSB) over control. Significantly the highest number of branches per plant (4.58) and dry weight of root nodules per plant (27.15 mg) were recorded under the same treatment. Yield attributes i.e. number of pods per plant (32.76) and test weight (43.60 g) were remarkably improved by biofertilizer treatment. These values were recorded significantly the highest under Abstract v treatment B1 (Rhizobium + PSB) over the treatment B0 (without Rhizobium + PSB). Pod length and number of seeds per pod did not differ statistically due todifferent levels of biofertilizer. Application of treatment B1 (Rhizobium + PSB) recorded significantly the highest seed (1212 kg/ha) and haulm (2816 kg/ha) yields as compared to treatment B0 (without Rhizobium + PSB). But, different levels of biofertilizer did not show significant variation on harvest index of greengram. The biofertilizer treatment recorded significantly the highest protein content (22.30%) in greengram seeds under treatment B1 (Rhizobium + PSB). The highest values with respect of nitrogen and phosphorus content in seed and haulm as well as nitrogen and phosphorus uptake by seed and haulm was recorded under the same treatment. Available nitrogen in soil after harvest of greengram was not influenced significantly due to biofertilizers. Application of treatment B1 (Rhizobium + PSB) recorded significantly the highest available phosphorus (30.82 kg/ha) in soil after harvest of greengram on pooled basis. Interactions between phosphorus and biofertilizer brought out significant variations in dry weight of root nodules per plant, number of pods per plant, seed yield, nitrogen uptake by haulm and phosphorus uptake by seed and haulm. The interaction between nitrogen and phosphorus also showed significant difference in case of nitrogen content in haulm. Abstract vi Significantly the highest seed yield (1322 kg/ha) was produced under the treatment combination of P3B1 (phosphorus @ 40 kg/ha + seed treatment of Rhizobium and soil application of PSB). Whereas, significantly the lowest seed yield (998 kg/ha) was observed under treatment combination P1B0. Significantly the highest values with respect to grain (2094 kg/ha) and stover (3868 kg/ha) yields of succeeding summer maize were observed under residual effect of treatment N3 (30 kg N/ha) applied to preceding greengram crop followed by treatments N2 (20 kg N/ha) and N1 (10 kg N/ha). Residual effect of treatment P3 (40 kg P2O5/ha) recorded significantly the highest grain (2080 kg/ha) and stover (3874kg/ha) yields of succeeding summer maize over treatments P2 (30 kg P2O5/ha) and P1 (20 kg P2O5/ha). Residual effect of biofertilizer did not exert their significant influence on seed and stover yields of succeeding summer maize. The highest net realization of ` 85112/ha with maximum BCR of 1.98 was secured under treatment N3 (30 kg N/ha). In case of different levels of phosphorus, treatment P3 (40 kg P2O5/ha) recorded the highest net realization of worth ` 84652/ha with BCR of 1.88. While in case of biofertilizer, the maximum net realization of ` 83620/ha with BCR value of 1.95 was accrued under treatment B1 (Rhizobium + PSB). Abstract vii On the basis of two years field experimentation. It can be concluded that greengram fertilized with nitrogen @ 20 kg/ha from Urea, phosphorus @ 40 kg/ha from SSP at the time of sowing along with seed inoculation of Rhizobium (AAU native isolated GG-1, Spp. selenitroreduces) @ 5 ml/kg seed and soil application of PSB (PAB-16, Bacillus coagulans) @ 1 L/ha gave higher production of greengram. However, application of 30 kg N + 40 kg P2O5/ha coupled with seed inoculation of Rhizobium @ 5 ml/kg and soil application of PSB @ 1 L/ha to preceding greengram along with 50% RDF (50 kg N + 25 kg P2O5/ha) to succeeding summer maize gave higher yield and net realization of greengram-maize sequenceThesisItem Open Access “Influence of dates of sowing and irrigation scheduling (IW:CPE Ratios) on growth, yield attributes and seed yield of Cress (Lepidium Sativum L.) under middle Gujarat conditions”.(Anand Agricultural University, Anand, 2013) ANIKET ARVIND UMALE; Dr. J.J.PatelA field experiment was conducted during rabi season of the year 2011-12 at College Agronomy Farm, B.
