    Density of Population Test of Yellow Stem Borer S. incertulas (Walker) (Lepidoptera: Pyralidae) and Varieties Rice to Preferences and Levels of Crop Damage on SRI Cultivation
    (2016-11-07) Ria, Elly Roosma; Turmuktini, Tien
    Research has been carry out to study the density of population test of yellow stem borer S incertulas and varieties Rice to preferences and levels of deadheart and whiteheart attack on SRI cultivation is done in the home screen Experimental Station Department of Plant Pests and Diseases Jatinangor Faculty of Agriculture, Padjadjaran University, from October 2011 until January 2012. The design used was a randomized block design with two factors factorial pattern and replicated three times. The first factor is the density population of yellow stem borer consists of four levels ie p1: 5 pairs of moth, p2 : 10 pairs of moth, p3: 15 pairs of moth, and p4 : 20 pairs of moth. Second factor is a rice varieties consists of four levels, namely: v1: Inpari-1 varieties, v2 : Inpari-13 varieties, v3 : Sarinah varieties, and v4 : Ciherang varieties. The results showed that 5 pairs moth of yellow stem borer can caused deadheart and whiteheart attack on the varieties Sarinah lowest and the varities Inpari-1 highest.

    Response of Rice Growth as The Results of Phosphate Fertilizer in Different Planting System Applications
    (2016-11-07) Kantikowati, Endang; Antralina, Merry; Turmuktini, Tien
    The study aimed to evaluate the effect of phosphate fertilizers and planting systems on plant height, shoot/root ratio, and root length. The experiment has been conducted at Experimental Station and Training Center for Agriculture Development, Padjadjaran University at Jelekong distric, Bandung Regency, West Java, at 628 m above sea level, from May 2012 until August 2012. It was arranged in Factorial Design with three replications. The first factor was planting system (conventional, legowo 2:1 , and twin seedling ) and the second factor was phosphate fertilizer (0 kg ha-1 ; 25 kg ha-1; 50 kg ha-1; 75 kg ha-1; and 100 kg ha-1).The experimental results has indicated that there are no interaction on shoot/root ratio and root length, but there was an independent effect on plant height in twin seedling system.
