Investigation was carried out on air layering in guava as influenced by growth regulators and Azospirillum was carried out in the Orchard, Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar during 2013-14 aimed to find out suitable ischolar_main inducing treatment in mature shoot air-layers of guava cv. L-49. There were 14 treatment combinations with three replications laid out in Randomised Block Design. In general, both growth regulators viz., IBA, NAA alone and in combination with Azospirillum favoured ischolar_maining in air-layers. Among the different combinations, the layers which had received Azospirillum 37.5g + IBA (Indole butyric acid) 3000 ppm + NAA (Naphthalene acetic acid) 3000 ppm (T12) recorded significantly higher percentage (91.68%) of ischolar_maining with desirable ischolar_main characters such as higher number of primary and secondary ischolar_mains, longer length of primary ischolar_mains and higher girth of primary ischolar_mains. Next to this treatment, the other favorable treatments were IBA, 3000 ppm + NAA, 3000 ppm (T6), IBA, 2000 ppm (T1), Azospirillum37.5g + IBA, 4000 ppm (T8), Azospirillum37.5 g + IBA, 6000 ppm (T9), Azospirillum 37.5 g + IBA 2000 ppm + NAA 2000 ppm (T11). The use of medium concentration (3000 ppm) of both the growth regulators (IBA and NAA) with Azospirillum 37.5g was more effective as compared to either lower (2000 ppm) or higher (6000 pm) concentrations of IBA and NAA.

An investigation was carried out at the Department of Horticulture, Faculty of Agriculture, Annamalai University during 2014-2015 to evaluate the performance of eight sapota cultivars, viz., PKM 1, Virudhunagar, Kirthibarthi Round, Cricket Ball, CO 2, Pala, Oval and Kirthibarthi Oval was studied in two seasons viz., February to April (peak season I) and July to September (peak season II). The experiment was laid out in Randomized Block Design (RBD) in three replications. With regard to quality characters, the cultivar Virudhunagar was found to be superior followed by CO 2.

The experiment was laid out in Randomized Block Design (RBD) in three replications. The per se performance of the cultivar Cricket ball excelled the other cultivars upon evaluating for growth characters like tree height, tree circumference, shoot length, shoot girth, number of leaves per shoot, leaf length and leaf breadth followed by CO 2 and Virudhunagar.

Investigation was carried out on air layering in guava as influenced by growth regulators and Azospirillum was carried out in the Orchard, Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar during 2013-14, aimed to find out optimum concentration for maximum survival percentage in mature shoot air-layers of guava cv. L-49. There are 14 treatment combinations with three replications laid out in Randomised Block Design. With regard to survivability of ischolar_mained layers, maximum survival percentage (98.14%, 60 days after separation) was noted in the layers treated with Azospirillum 37.5g + IBA 3000 ppm + NAA 3000 ppm (T12).

A field experiment was carried out to study the effect of plant growth regulators on growth and yield of brinjal cv. ANNAMALAI. The growth regulators were applied in three different concentrations viz., NAA (25, 50 and 100 ppm), GA3 (50, 100 and 200 ppm) and ethrel (50, 100 and 200 ppm). The experiment was laid out in Randomized Block Design (RBD) with ten treatments and three replications. The earliness in flowering, number of flowers, fruit set percentage, fruit length, fruit girth, fruit weight and yield per plant were registered in the plants sprayed with GA3 @ 50 ppm. The fruits obtained from the plants that were sprayed with GA3 @ 200 ppm also recorded highest total soluble solids and ascorbic acid content, which ultimately had better taste than the other treatments. Among the growth regulators tested, GA3 @ 50 ppm was found to produce best results in improving the growth and yield of brinjal cv. ANNAMALAI.Keywords

A field experiment was carried out to study the effect of plant growth regulators on growth and yield of brinjal cv. ANNAMALAI. The growth regulators were applied in three different concentrations viz., NAA (25, 50 and 100 ppm), GA3 (50, 100 and 200 ppm) and ethrel (50, 100 and 200 ppm). The experiment was laid out in Randomized Block Design (RBD) with ten treatments and three replications. The results of this experiment revealed that the plants that was sprayed with GA3 @ 200 ppm evinced better performance for the production of plant height, number of primary branches, number of secondary branches, number of leaves, leaf area and leaf area index.Keywords
