Abstract

Vetiver (Vetiveria zizanioides L.) plants are able to protect the soil from erosion and are tolerant of salinity stress. However, at high salinity levels, vetiver plants show a decreasing growth. The application of gibberelin is expected to increase the growth of vetiver in salinity stress conditions. The purpose of this study was to evaluate the growth responsiveness and production of vetiver the application of gibberelin under salinity stress conditions. This research was conducted in the green house of the Faculty of Agiculture, Universitas Sumatera Utara, Medan. This study used a non-factorial completely randomized design, namely the salinity stress (S) which consisted of 3 levels, each treatment was repeated 3 times, so that 9 treatment combinations were obtained: the concentration of gibberelin was 0 (no treatment), 50 ppm and 100 ppm.

Abstract

The rice productivity in Panai Tengah was still relatively low, producing 4.75 Mg ha-1, compared to the national production of 5 to 6 Mg ha-1. Low rice productivity was caused by limiting factors in land use, namely, physical and biological factors, soil chemistry, and agricultural systems. Providing organic fertilizer or municipal waste compost is one way to overcome the constraints on the soil’s physical, biological, and chemical characteristics. This study aims to determine the response to the growth and yield of rainfed rice fields in Kecamatan Panai Tengah with a dose of Municipal Solid Waste Compost (MSWC). This research was conducted by taking soil samples in the rainfed rice fields and then analyzing them in the experimental field at the Faculty of Science and Technology, Labuhanbatu University. The analysis stage was for six months, from seeding to harvesting. The methodology for this study was a non-factorial randomized block design consisting of 7 treatments. The result showed that applying MSWC at a dose of 18 Mg ha-1 showed high yields. The recommendation to farmers was to give 18 Mg ha-1 of MSWC to increase the yields of their rice fields.

Abstract

The aims ofthis research is to determine the response of growth and production of sweet corn (Zea Mays Saccharata Strurt) to the application of liquid organic fertilizer coconut water and tea waste compost. The research cobducted in Trial Garden of Agriculture Faculty of Medan Area University, Kolam Street no 1 Medan Estate with height 22 m above sea level. Plat topografi and alluvial soil type was done since June up to September 2018. The research is using Random Designing Group Factorial with two factors, such as coconut water POC (K0 = Control (purn); K1 = coconut water POC 50 ml/L; K2 = coconut water POC 100 ml/L; K3 = coconut water POC 150 ml/L), and the giving factors of tea pulp compost (K0 = Control (purn); K1 = tea pulp compost 5 Ton/Ha; K2 = tea pulp compost 10 Ton/Ha; K3 = tea pulp compost 15 Ton/Ha). Repeatedly twice. Parameter which observed are the height of the plant, leaf amount, diameter of the stem, the sample each plot of plant production, plant production each plot. The result of this research is two show that the giving of coconut water POC is not really influencing to the treatment and giving of the tea pulp compost to the treatment and giving of the tea pulp compost is really influencing to the height of the plant, the sample of plant production each plot, plant production each plot but not really influence to the leaf amount and diameter of stem as well as combination among coconut water POC and tea pulp compost is not influencing to all treatments.
