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

Morphological observations were a preliminary identification for plant adaptation to shading stress. This research was conducted at Cengkeh Turi, North Binjai Subdistrict (32 meters above sea) from April to June 2017, used Split Plot Design. The main plot was shade (0, 25, 50 and 75%) and the sub plot was pepper varieties (Bengkayang and Lokal Binjai). The results showed that two varieties of pepper used have the same responses on the shoot dry weight, root dry weight, number of leaf area. Shading stress treatment had a significant effect on shoot dry weight and the number of leaf areas. Lokal Binjai was more adaptive to shading stress compared to Bengkayang. Light intensity 25% it is a good condition for two varieties of pepper
