Abstract

The low productivity of soybean in Indonesia was caused by natural factors, biotics, cultivation techniques and soybean plant physiology. Extensification program to meet the needs of soybeans can be solved by using dry land, of drought stress. The study was conducted at the Screen house Faculty of Agriculture, Universitas Sumatera Utara, Medan (± 32 meters above sea level), on July to October 2017, using a randomized block design with 2 treatment factors. The first factor is drought stress with 3 levels ie 80% ; 60% and 40% field of capacity(FC) . The second factor is an ascorbic acid with 4 levels of concentration ie: 0 ; 100 ; 200 and 300 ppm.. The observed of variables ie number of leaves, total leaf area, dry seed weight per plant, 100 seed weight and harvest index. The results showed that the increased treatment of drought stress (80 – 40% FC) had the significant on all observed variables. The Ascorbic acid treatment no significant on all observed variable with the average number of leaves and the highest total leaf area at use 200 ppm ascorbic acid and the lowest at control treatment. The interaction no significant on all observed variable.

Abstract

The aims of this study was to determine the effect of organic liquid fertilizer concentration and varieties on the growth and production of several varieties rice. This research had done at Desa Sendang Rejo, Kecamatan Binjai, North Sumatera with the 50 meters of sea level, from August until November 2016. This research used randomized block design with 2 factor treatments. The first factor was organic liquid fertilizer concentration with 4 levels 0 cc/ litre of water, 3 cc/liter of water, 6 cc/ litre of water and 9 cc/liter of water. The second factor was varieties with 3 levels Ciherang, Inpari 30 and Inpari 32. The result showed that the concentration organic liquid fertilizer significantly effect the plant height, tillers, 1000 grain weight and production per plant. Best result is obtained in treatment 9 cc/litre of water.

Abstract

Sweet corn is a crop has a very good nutrient and tastes sweet and Calsium influenced contain. Ultisol is one of the soil that spreaded vastly in Indonesia, up to 25% of Indonesian total terrestrial area. Ultisol is an acidic soil, hence clacification can be applied to deal with it. The purpose of this research was to determine the growth response of sweet corn in two sources of calcium nutrients application to Ultisol soil. This research was conducted in the gauze of the Faculty of Agriculture, University of Sumatera Utara with an altitude of ± 32 m above sea level starting from October 2017 to December 2017. This research used a Non Factorial Completely Randomized Design with 7 treatments and 4 repetition, the treatment of which was calcium nutrient, shell egg (9.22 g / 15 kg soil), eggshell (13.84 g / 15 kg soil), eggshell (18.45 g / 15 kg soil), dolomite 1 x Aldd (equivalent to 9.22 g / 15 kg of soil), dolomite 1.5 x Aldd (equivalent to 13.84 g / 15 kg of soil), dolomite 2 x Aldd (equivalent to 18.45 g / 15 kg of soil). The results showed that the two sources of calcium nutrients (eggshell or dolomite) applications had no significant effect on plant height, leaf number, stem diameter, canopy and root wet weight, and canopy and root dry weight.
