Analysis of leaf characteristics of local moringa (moringa oleifera lam.) Germplasms in Sri Lanka Kodikara, C. M.; Weerasekara, D.; Sujanthika, V.; Hettiarachchi, Pradeepa; Mubarak, A. N. M. Moringa (Moringa oleifera Lam.) is one of the most popular vegetable crop species cultivated throughout the tropics with a high medicinal and nutritive value. However, there were no evidences regarding crop improvement, breeding or germplasm evaluation programmers reported for this valuable crop. Hence, this study was conducted in Grain Legume and Oil Crop Research and Development Center, Angunakolapelessa to identify the best Moringa accessions with desirable morphological characteristics. Twenty accessions representing 4 districts which were maintained in field plots with 3 replications per accessions, were arranged in a Randomized Complete Block Design (RCBD). At 90 days after field planting, the 4 leaf morphological characters were recorded and hierarchical cluster dendrogram was generated to reflect their relatedness using cluster analysis. Our results revealed that the leaf dry matter content ranged between 22.1% and 26.4%. The maximum value of 26.4% was recorded in the M94 accession, which was collected from the Kurunegala district. Mean tripinnate leaf length ranged between 62.5±0.5 mm and 82.0± 4.68mm whilst the tripinnate leaf width ranged between 52.3 mm and 69.3 mm. Accordingly, the highest leaf dimensions were recorded in accession no. M14 and M97 collected from Batticaloa and Jaffna districts respectively. According to the dendrogram, accessions M14 and M97 were resulted as the most distinctive accessions in the study. Conversely, M14, M94 and M97 were clustered in one group depicting that the moringa leaf traits subjected to vary according to the geographical location within the country.

Factors affecting the performance of artificial insemination in cattle at the Kalmunai veterinary range Thaiuba, Assanar; Nikzaad, R. M. Artificial insemination has created a great deal of interest in genetic circles during the last few years. The objective of this study was to find the success rate, and factors affecting the AI performance of the smallholder, and to expand the efficiency of AI services. The research revealed that in the last five years the total number of AI was 65 to 70 and it’s covering the average 55 of the total cattle population of the government veterinary range Kalmunai. And the total conception rate was 79.4%, with crossbreeds having a higher conception rate. The frequency of repeated AI was relatively low, and norepeat AI performance was observed in 2017. Last five years, most AI performed with Jersey (34.2 %), Sahiwal (32.8 %) and Friesian (27.4 %). Further, the overall success rate of AI and its impact on genetic variation of the breed-able cattle population were low in the studied area. Performance and efficiency were influenced by poor infrastructural facilities, low motivation and mobility of field staff, inadequate veterinary coverage and resources and farmers' ignorance and low motivation. These results suggested the need for farmer awareness, training, and extension in this region. This is a result of farmers' lack of knowledge of the significance of the proper time of service and inadequate communication across smallholding farms. Therefore, emphasis must be placed on resolving these defects
