The experiment was laid out in the Randomized black design (RBD) with three replications, various micronutrients viz., chelated potassium @ 1% , ZnSo4 @ 0.5% , Mo @ 0.5% , B @ 0.5% were sprayed on plants 30, 60, and 90 DAP to formulate nine treatments combination including one control. The tuberose cultivar prajwal used for this study. The various treatments significantly influenced the growth attributes of tuberose. Among the different treatments, T9 ( chelated potassium humate @ 1% + Zn @ 0.5% + Mo @ 0.5% + B 0.5% on 30, 60,and 90 DAP) was found to be the best in all growth and physiological characters viz., plant height (48.12 cm), number of side shoots per plant (8.92), number of leaves per plant (35.16), plant spread (27.95 cm2), leaf area (52.15 cm2) , chlorophyll content (0.99 mg g-1) and dry matter production ( 24.18 g plant -1). From the above results, it is concluded that T9 (chelated potassium humate @ 1% + Zn @ 0.5% + Mo @ 0.5% + B 0.5% on 30, 60,and 90 DAP) was found to be beneficial and economically feasible for the effective cultivation of tuberose (Poliyanthes tuberose) cv. prajwal under open field condition in the coastal ecosystem.

It belongs to the family Liliaceae. Aloe contains cathartic anthraglycosides as its active principles. These are mostly c-glucosides, notably barbaloin, which is a glucoside of aloe emodin. The concentrations of these glucosides vary with the types of aloe ranging from 4.5 to 25 per cent of aloin. Considering the imperativeness of the crop, a study was conducted in view of improving the quality and therapeutic value which could benefit the farming community and pharmaceutical industry. The present research work was carried out at the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar, Tamil Nadu. The experiment was laid out following the principles of Factorial Randomized
Block Design with 9 treatment combinations replicated thrice by adopting the spacings of (60 x 30 cm, 60 x 45 cm and 45 x 45 cm). The field lay out was prepared with a plot size of 3 X 3 m (9 square meters). Calculated quantities of farmyard manure, decomposed coir pith and vermicompost were applied as per the treatments to the different plots after field preparation. The results of the experiment revealed that the application of vermicompost @ 5 t ha-1 + Azospirillum @ 2 kg ha-1 and a spacing of 60 x 45 cm significantly increased the growth characters such as plant height, plant spread, number of leaves, leaf length, leaf width, leaf circumference
and total chlorophyll content. The nutrient uptake by the plants and post harvest soil nutrients were also found to be maximum by the application of vermicompost @ 5 t ha-1 + Azospirillum @ 2 kg ha-1.

At Puthur village, Thalaivasal taluk, Salem district, from February to May 2022, a group of 33 germplasm lines were tested using a Randomised Block Design with three replications. The findings indicate that the clustering of genotypes revealed that Cluster I comprises highest number of genotypes (19) followed by cluster III comprising of 6 genotypes.Cluster IV had the greatest intra-cluster distance, which was followed by clusters II, III, I and V. The genotypes found in clusters IV and III had satisfactory values for the intercluster distance and the cluster mean. As a result, that genotype belongs to cluster IV, and cluster III may be utilised as parents in a hybridization programme to produce hybrids that are ideal for tropical climates.

It is thought to have originated in tropical Africa. The experiment comprises of 33 genotypes of muskmelon collected from various location. During the months of February to May 2022, the plants were raised in three replications with spacing of 3 m x 60 cm using a Randomized Block Design (RBD) at Puthur village, Thalaivasal taluk, Salem district. The result shows, estimates of high PCV and GCV (>20%) were recorded in fruit yield per plant (60.16 & 60.09) followed by seed yield per fruit (41.70 & 41.62), average fruit weight per plant (41.56 & 41.49), seed yield index (39.50 & 39.42) respectively. Highest heritability (>60%) along with high genetic advance as per mean (>20%) were noticed in fruit yield per plant (99.79 & 98.55) followed by average fruit weight per plant (99.66 & 85.32), seed yield index (99.59 & 81.03) and seed yield per fruit (99.58 & 85.55) respectively.

Breeders select parents with high mean values as an added benefit for crossing programmes. The present investigation was carried out to evaluate the performance of muskmelon genotypes for growth and earliness attributes. Muskmelon (Cucumis melo L.) is one of the most well-known desert vegetables, belong to the Cucurbitaceae family. Thirty-three germplasm lines were collected from different regions of India. The experiment was conducted at Puthur village, Salem district, and evaluated under Randomised Block Design with three replications during February to May 2022. The findings indicate that the genotypes CM 2, CM 16, CM 11, CM 19, CM 7, CM 13 and CM 22 reported as elite genotypes were exhibited higher values for different traits like days to first female flower opening, first female flowering node, number of vines per plant, vine length (cm), sex ratio and days to first fruit harvest. As a result, the above mentioned seven genotypes are used in the hybridization programme, could be exploited to develop elite cultivars with maximum growth and earlier in flowering and harvest.

Micronutrients are essentially as important as macronutrient to have better growth, yield and quality in plants. Micronutrients play a prime role in the production of any crop because of it is direct influence on crop physiology. Micronutrients are involved in all metabolic and cellular function. Plants differ in their need for micronutrients such as boron (B), iron (fe), zinc (zn), copper (cu), chloride (cl), Manganese (Mn), Molybdenum(Mo), and Nickel (Ni). Foliar application of nutrients is particularly a useful technique which can be designed to meet plants specific needs for one (or) more micro (or) macro nutrients especially
trace minerals and enable to correct deficiencies, strengthen weak (or) damaged crops, speed up growth and to grow better (Said-Al Ahl and Mahmoud, (2010). The literature pertaining to the effect of micronutrients of zinc, boron, molubdenum, potassium humate and some combinations on flower crops is reviewed here under.

Among the parents, maximum GCA effect was found in EC 102605 and Kashi Kranti for days to first flowering, EC 112112, and Kashi Kranti for days to first fruit harvest and EC 109454 and Arka Anamika for number of immature seeds per fruit. The cross combinations EC 102605 x Aruna, EC 112112 x Kashi Kranti and EC 169335 x Aruna exhibited maximum significant negative sca effects for days to first flowering, days to first fruit harvest and number of immature seeds per fruit respectively. The SCA variance was higher than the GCA variance that indicates the presence of preponderance of non-additive gene action for days to first harvest and number of immature seeds per fruit. The GCA variance was higher than the SCA variance that indicates the presence of preponderance of additive gene action for days to first flowering.

Micronutrients are essentially as important as macronutrient to have better growth, yield and quality in plants. Micronutrients play a prime role in the production of any crop because of it is direct influence on crop physiology. Micronutrients are involved in all metabolic and cellular function. Plants differ in their need for micronutrients such as boron (B), iron (fe), zinc (zn), copper (cu), chloride (cl), Manganese (Mn), Molybdenum(Mo), and Nickel (Ni). Foliar application of nutrients is particularly a useful technique which can be designed to meet plants specific needs for one (or) more micro (or) macro nutrients especially
trace minerals and enable to correct deficiencies, strengthen weak (or) damaged crops, speed up growth and to grow better (Said-Al Ahl and Mahmoud, (2010). The literature pertaining to the effect of micronutrients of zinc, boron, molubdenum, potassium humate and some combinations on flower crops is reviewed here under.
