Growth study of pandemics durian (Durio zibethinus L.) based on nutritional analysis

Abstract

Background and Objective: Durian pandemic can be planted in lowland to highland because it has high adaptive character. However, further studies on durian cultivation techniques are needed because durian is an annual plant and did not have continuous growth but cyclical. The purpose of this study was to know the relationship of nutrient content with growth of durian. Materials and Methods: The research was conducted in Ngembal village, Tutur Nongkojajar district, Pasuruan city. The research was conducted from May, 2016 until October, 2016. This research was informative without any treatment but samples were collected 4 leaves on the upper, middle and lower stratum. Then quantitative analysis was conducted on carbon and nitrogen total content. Each sample taken from plants durian (Montong, Matahari and Kani) has been fruitful. The results were analyzed with SPSS 17.0 software processed by correlation analysis. Results: The results showed on the generative phase (flowering) in durian Kani and Montong is characterized by the absence of growth in stem diameter but in durian Matahari, there is still increase in the number of stem diameters. The decrease of shoot quantity is also characteristic of the inclusion of generative phase at Kani, Montong and Matahari. Conclusion: The flowering phase indicated a decrease in the number of shoots, total nitrogen content and an increase in the organic carbon content in the leaves.
