ABSTRACT Palm oil production depend on the rain and the age composition of plants. The purpose of this research was to determine the effect of rainfall and rainy day as well as the correlation of both on palm oil production in plants aged 7, 10 and 13 years. This research used primary data available in company administration, in the form data of production of fresh fruit bunches (FFB); componen production data as total bunches, average bunches weight, and total of productive trees in 2013, 2014,2015. Rainfall and rainy days data were taken a year before the production data in 2012, 2013, 2014. Analysis method used are double linier regression and correlation analysis. Model tested by classic asumption consists of normality test, heteroskedasticity test, multicollinearity, and autocorellations test by using statistic software SPSS.v.20 for windows. The result of t-partial test showed that rainfall variable had an effect not significantly on age 7, 10 and 13 years at alpha 5% (Sig > α 0.05). While on rainy day variable showed that rainy day had significant effect at age 7 year at alpha 5% (Sig < α 0.05) while at age 10 and 13 year rainy day had an effect not real. While on the regression analysis shows that rain fall and rainy day simultaneously variables unsignificanted with alpha 5% (Sig <α 0.05) to increase the production of FFB at the age of 7, and 10 years. While rain fall and rainy day variables significanted to increase the production of FFB at the age of 13 years. The influence of rainfall and rainy days the FFB production each from ages 7, 10 and 13 years was 50,4%, 44,7%, and 43,8% influence by other variables not included on the model. Correlation results in plants was 7, 10, and 13 years with two-way analysis test at 1% level showed variable rainfall and rainy days have a strong relationship, and positive direction. Keywords: FFB production, rainfall, rainy day.

ABSTRACT Taro tuber is one of the few commodities tubers that can be used as an alternative source of food other besides rice that is both healthy and safety. Cultivating of taro and increase production to do some of them use the alternative media composition suitable cropping and NPK fertilizer. This research was conducted in Jalan Klambir Lima Kecamatan Sunggal, Medan, with altitude ± 25 meters above sea surface began from April to Juli 2016. This research used factorial randomized block design with two factors. The first factor was growing media composition (top soil (control)); top soil : sand (1:1)); top soil : sand : empty bunches of palm oil compost (1 : 1: 1)); top soil : sand : empty bunches of palm oil compost (2: 1 : 1)); top soil : sand : empty bunches of palm oil compost (3: 1: 1)) and the second factor is doses of NPK fertilizer (0; 2; 4; 6 g/polibag). Parameter observed was plant height, total leaf area, plant fresh weight, shoot dry weight, and root dry weight. The result of this research showed that growing media composition were significantly effect to plant height parameter 2 week after planting, total leaf area, plant fresh weight, shoot dry weight, root dry weight, and ratio of shoot and root. doses of NPK fertilizer composition were significantly effect to total leaf area parameter, plant fresh weight, and shoot dry weight. Interaction of growing media composition and dose of NPK fertilizer were significantly effect to plant height 2-9 week after planting and plant fresh weight. Keywords : growing media, NPK fertilizer, taro

The availability of nutrients in the soil is a major factor affected the growth and production of plants. This study aims to determine the response of compost enriched chicken egg shell and beneficial microbes (rhyzobium + mycorrhiza) to some aspects of soil properties of Inseptisol as well as the growth and production of soybeans. This research was conducted in field trial UPT Balai Induk Palawija Tanjung Selamat and Soil Biology Laboratory Faculty of Agriculture University of North Sumatra. This research used was a Factorial Random Block Design. The first factor was chicken egg shell enriched consist of 4 treatments 0 ton/ha, 10 ton/ha, 20 ton/ha, 30 ton/ha and second factor was beneficial microbe (rhyzobium + mycorrhiza) consist of 2 treatmenst 0 g/polybag and 10 g/polybag. The results showed that the enriched compost enriched chicken egg shell increased the soil pH, C-organic, Ca-exchanged, shoot dry weight , the amoont of root nodule, percentage of degree of root infected by mycorrhiza, and weight of 100 seeds and the application of beneficial microbes increased root nodule and root infection degree.

This research was conducted to find out the effect of coconut water concentration and the duration of true shallot seed soaking on the growth and production of shallot. This research was conducted on community farm at Jalan Bunga Rampai II Gang Saudara, Kelurahan Simalingkar B, Kecamatan Medan Tuntungan, Medan, began from April to August 2017. The research used a Factorial Randomized Block Design with 2 treatment factors: coconut water concentration at 5 levels: 0; 25; 50; 75; 100 %, and duration of seed soaking at 3 levels: 60; 120; 180 minutes. The parameters observed were number of plant height at 2 to 7 weeks after transplanting (WAT), bulb diameter, and dry bulb weight. The result of this research showed that coconut water concentration had no significant effect on all observation parameter. The duration of seed soaking treatment had significant effect on plant height and dry bulb weight. The highest dry bulb weight was obtained at 120 minutes of seed soaking. The interaction of coconut water concentration and the duration of true shallot seed soaking treatment had no significant effect on all observation parameters.Keywords: coconut water concentration, duration of seed soaking, true shallot seed
