Abstract:
Introduction: The research was aimed to obtain the dosage of NASA liquid organic fertilizer (LOF), goat manure (GM) and combinations are appropriate to support the growth and yield of wax apple. Materials and Methods: This research was conducted at Payaroba Street, Binjai City, North Sumatra Province from Juni to December 2018. This research used the randomized block design factorial within the first factor was NASA LOF (C0= 0 ml.l-1; C1= 1 ml.l-1; C2= 2 ml.l-1; C3= 3 ml.l-1 in water), and the second factor was GM (K0= 0 kg.polybag-1; K1= 0.5 kg.polybag-1; K2= 1.0 kg.polybag-1; K3= 1.5 kg.polybag-1) using three replications. Parameters were analyzed using the ANOVA and continued with the least significance different at rate of 5%. Results: GM significantly increased the plant height, stem diameter, number of flower, and fruit weight of wax apple along with increasing doses until 1.5 kg.polybag-1 of 11.76%; 16.70%; 12.90%; and 7.55% respectively, and accelerating the flowering of 2.98 days compared to un-treated. The application of NASA LOF significantly increased the plant height, stem diameter, and number of flower by wax apple along with increasing doses until 3 ml.l-1 water by 7.51%; 46.61%; and 11.04%, and accelerating the flowering of 5.16 days compared to un-treated. The combination of NASA LOF at 2 ml.l-1 water and GM at 1.5 kg.polybag-1 significantly increased the stem diameter by 52.89% compared to the control combination. However, it did not show a significant effect on plant height, flowering, number of flower, and fruit weight of wax apple.

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: The purpose of this study was to determine the dosage of inorganic fertilizers, soaking time of the inoculation of the legume bacteria strains which were suitable for the growth and yield of peanut in tidal lowland. Materials and Methods: This research was conducted at tidal lowland in Sei Ular Village, Secanggang sub-District, Langkat District, North Sumatra from September to December 2019. The research used randomized block design in factorial. The first factor is the dose of inorganic fertilizers consisting of P0 = un-fertilizer (control), P1= urea 50 kg.ha-1 + TSP 180 kg.ha-1 + KCl 50 kg.ha-1, P2= urea 75 kg.ha-1 + TSP 205 kg.ha-1 + KCl 75 kg.ha-1, P3= urea 100 kg.ha-1 + TSP 230 kg.ha-1 + KCl 100 kg.ha-1. The second factor was the soaking time of the Bradyrhizobium japonicum bacterial strain consisting of T0= un-soaking time, T1= soaking time for 3 minutes, T2= soaking time for 6 minutes, and T3= soaking time for 9 minutes. Parameters were analyzed using ANOVA and BNJ analysis 5%.· Results: The application of urea 50 kg.ha-1 + TSP 180 kg.ha-1 + KCl 50 kg.ha-1 significantly increased the plant height, number of leaves, and root volume and showed the highest number of active nodules, dry pods.plot-1 and seed weight.plot-1 compared to other doses. The seed soaking time with the Bradyrhizobium japonicum strain and their interactions showed insignificant differences in all parameters of peanut plants in tidal lowland.

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: 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.
