Abstract

Introduction: This research was determined the growth response of cocoa (Theobroma cacao L.) in N-fertilizer and sugarcane bagasse compost. Materials and Methods: This research was conducted at agricultural area of ​​Sejati Street, Sari Rejo Village, Medan Polonia Sub-District, Medan. This research was conducted from August until December 2015. This research used therandomized block design in factorial. The first factor was N-fertilizer with 4 rates, 0 g.polybag-1 (P0), 2 g.polybag-1 (P1), 4 g.polybag-1 (P2),and 6 g.polybag-1 (P3). The second factor was the provision of sugarcane bagasse compost with 4 rates, 0 g.polybag-1 (K0), 2 g.polybag-1 (K1), 4 g.polybag-1 (K2) and 6 g.polybag-1 (K3). The observed data were analyzed by the F-test, and continued with the DMRT at level of 5%. Results: Composting bagase significantly affected the leaf area of cocoa seedling at 2 and 4 weeks after planting. The application of N-fertilizer had significant affected the number of leaves for cocoa seedling. The interaction of P2K2 (6 g.polybag-1 N and 4 g.polybag-1 of bagasse compost) showed the highest fresh- and dry-weight of cocoa seedling compared to other interactions, although the effect was not significant.

Abstract

Introduction: This research was aimed to determine the relationship pattern of rainfall, humidity, and rainy day on the increase in pepper yield in North Sumatra. Materials and Methods: This research used the time-series data on factors of rainfall, humidity, rainy day, and yield of pepper for 14 years (2005 until 2018). Data analysis used the multiple linear regression analysis with the Eviews 10 software. Results: The rainfall, humidity, and rainy day simultaneous significantly increased the pepper yield of 55.767% in North Sumatra. A 1% increase in humidity can increase the pepper yield by 0.455 ton, but a 1 mm.year-1 increase in rainfall and a 1 rainy day can decrease the pepper yield in North Sumatra by 0.503 and 1.866 ton, respectively. The humidity had the value positive, meanwhile rainfall and rainy day had the value negative in pepper yield.

Abstract

Introduction: Downy mildew control using pesticides has been used intensively and led to the onset of resistant strains. This research aims to find out the effect of bamboo vinegar administration on disease incidence, disease severity, disease progression, and growth of maize. Materials and Methods: This research was conducted from June to August 2020 in the laboratory and Screenhouse of the Faculty of Agriculture, Universitas Tidar. The experiment was experimentally conducted using a Completely Randomized Design (CRD) consisting of 3 treatments with 6. are plants. In each polybag used there are 3 maize so there are 54 plants tested. The treatment tested is of bamboo vinegar and maydis (negative control), of bamboo vinegar with inoculation P. maydis (positive control), application bamboo vinegar 2 ml l-1 with inoculation P. maydis. Observations on the agronomic influence of maize covering height, , and dry weight were analyzed using ANOVA at a significance of 5% followed by LSD test at the same real level using software R v. 4.0.2. Results: Bamboo vinegar showed lignification in the treatment of stronger bamboo vinegar in corn leaf tissue, did not decrease in disease incidence, but decreased the disease severity by 22.18% and decreased disease the progression by 34.74% based on AUDPC value. The growth of maize, bamboo vinegar-treated shows values are not significant negative control.
