Abstract

Efforts to increase the productivity and quality of tea shoots are strongly influenced by local climatic and weather conditions at each plantation location.  The existence of climate change globally causes climate change fluctuations and weather elements in almost all tea plantation locations in the world from year to year. Determination of the local climate at each tea plantation location is important in establishing a stable and sustainable production management program and the quality of tea shoots. The weather parameters used for the determination of the start of the local rainy season (AMH) and the start of the dry season (AMK) at the tea plantation location in Tritis hamlet are the amount of rainfall and basic rainy days determined by the Meteorology, Climatology and Geophysics Agency (BMKG).  Rainfall data and local dasarian days of rain for a period of one year were analyzed using subjective descriptive methods involving graphical analysis and spatial analysis. The results showed that the beginning of the rainy season (AMH) in Tritis tea plantation was included in scenario 4 where AMH occurred in October 3 with the amount of rainfall ˃ 50 mm and the number of rainy days ˃ 6 days while the beginning of the dry season occurred in May 2 with the amount of rainfall ˂ 50 mm and the number of rainy days ˂ 6 days.Key words:  AMH, AMK, Rainfall, Dasarian, Rainy Day, and Tea Plantation.

Abstract

Onion (Allium Ascalonicum L) are one of the leading horticultural commodities that have economic value. In cultivation, Fusarium wilt disease is often damaged caused by the fungus Fusarium oxysporum. This study aimed to examine the effect of biofertilizer application on fusarium wilt disease, growth and yield of onion. The treatments tested were Bion-up biofertilizer, KIBRT, Biostimulant, Azoto-Tricho, anthracol fungicide, and without biological fertilizer as a control. Using a randomized block design with three replications. Observation variables were the incidence of fusarium wilt disease, plant height, number and weight of tubers. The results showed that the application of biofertilizers (Bion up, KIBRT, Biostimulants and Azoto-Tricho) was effective in increasing plant height, number of bulbs, and bulb weight of onion bulbs, while controlling the development of fusarium wilt disease was more effective when using Bion up, KIBRT, and Azoto-Tricho.Keywords: Biofertilizer, Antracol, Shallots, Fusarium oxysporum

Abstract

 NaCl stress is one of the causes of inhibition and decreased growth of rice plants. The aim of the study was to obtain indicators of tolerance analysis and to analyze the tolerance of rice varieties Inpari-22 and mekongga to NaCl stress. The research was carried out at the Laboratory of Botany and Plant Physiology, Faculty of Agriculture, University of IBA in Palembang, in October-December 2021.The study used a completely randomized factorial design (RALF) 5 x 2. The first factor was the concentration of NaCl, which consisted of 0ppm (water), 2.500ppm, 5.000ppm, 7.500ppm and 10.000ppm. The second factor is rice varieties, namely Inpari-22 and Mekongga. The experiment consisted of 10 treatment combinations with 3 replications. Each experimental unit consisted of 50 seeds, so a total of 1,500 seeds. The results showed that soaking the seeds in a NaCl solution of 2,500-10,000 ppm for 48 hours could increase germination, vigor index, growth speed, growth synchronously and maximum growth potential. However, in subsequent growth there was inhibition and a decrease in plant height, root length, epicotyl length, plant weight and root weight at increasing NaCl concentration from 2,500 ppm -10,000 ppm. In this study, as an indicator of the analysis of seed tolerance to salinity stress, the observations of germination variables (germination, vigor index, growth speed, growth synchronously and maximum growth potential) and early growth half (plant height, number of leaves, root length, epicotyl length, plant weight and root weight) can be used.
