The resistance rice genotypes against bacterial leaf blight (Xanthomonas oryzae pv. oryzae). The research was conducted to analyze genotypes of rice that were resistant to bacterial leaf blight (BLB) disease. The experiment was conducted at the screen house

This study aims to determine the effect of tillage systems on the growth and production of corn. Materials and tools used in this study were: Corn seeds used in this study were Bonanza F1 Varieties, the basic fertilizer used was NPK BASF (15:15:15) 300 kg ha-1. The tools that will be used in this study are Scales, Caliper, Machetes, Hoes, Knives, Meters, Gembor, Buckets, Hend spayers and stationery. The experimental design used in this study was a non factorial randomized block design (RBD) 3 treatments with 3 replications. The factors studied include: Soil processing system (T) which consists of 3 (three) levels including: No Soil (T1), Minimum Soil (T2) and Maximum Soil (T3). Observation parameters observed were plant height, stem diameter, ear length, ear diameter, ear weight, ear weight per plot and ear weight per ha. The results showed that the tillage system had a very significant effect on plant height at the age of 21 HST, weight of crop cobs, weight of cobs per plot and weight of cobs per hectare. Significantly affected plant height at ages 28, 35 and 42 HST, stem diameter age 21.28, 35 and 42, but had no significant effect on cob length and ear diameter. The best treatment is found in the maximum tillage system (T3). Keywords: tillage system, corn, Bonanza F1 variety

This research aimed to observe the appearance of Coix lacryma-jobi L. as affected by number of seeds and plant spacing. Randomized Blok Design comprised of 2 factors (number of seeds, J; plant spacing, T) with 3 replications was arranged, while the parameters included plant height, stem diameter, number of leaf, length and width of leaf. The experiment was conducted at experimental field of Agriculture Faculty in Teuku Umar University, Meulaboh, from March to October 2017. The results showed that the number of seeds significantly affected plant height in 49 days after planting, 63 days after planting, and also showed a significant effect on leaf length in 77 days after planting. Statitical analysis showed the interaction effect among the factors. The most significant effect was observed in plant height and leaf length in 21 days after planting.

Aceh Province has many local varieties that are still cultivated by farmers, especially in the South-West Region of Aceh, the local rice needs to be identified and used as a source of genes in the assembly of new improved varieties to support food security and sustainable agriculture. Bacterial leaf blight (HDB) is one of the limiting factors in rice production. HDB disease is caused by Xanthomonas oryzae pv. oryzae (Xoo), which can reduce rice yield by 30-40%. However, the potential of these varieties as sources of resistance genes against HDB has not been evaluated. This study aims to determine and obtain the potential genotypes of local rice in the West-South Region of Aceh that are resistant to Bacterial Leaves Disease. The research was carried out at the Experimental Garden of the Faculty of Agriculture, Teuku Umar University, Meulaboh, West Aceh from January to completion. The research was carried out starting from the treatment and seeding, preparation of planting media, planting, observation variables: Plant height and number of tillers per age 60 HST, incubation period and length of the observed lesio: 21 HSI: Test results of potential local rice resistance in the West- South Aceh obtained 9 genotypes that are resistant to bacterial leaf blight. The genotypes are used as genetic sources for assembling new high yielding varieties Keywords : Bacterial, Bacterial leaf blight, rice of local varieties,
