The row spacing system on varieties of rice (Oryza sativa L.) in rain fed field, guided by Lisa Mawarni and Rosmayati. This research is to know the differences effect of row spacing system to growth and production of rice plant in rain water paddy field. This research had done at Desa Sendang Rejo, Kecamatan Binjai, North Sumatera with the 50 meters of sea level, from April until August 2015. This research used split-plot design with two factors and three replicates. The first factor was row spacing system (square, row spacing 2:1, row spacing 4:1). The second factor was varieties (Ciherang, Mekongga, and IR 64). The result show that the planting system effect was not significant to all parameters but the varieties significantly influence the high plant, tiller numbers, leaf length , weight of panicle per sample, weight of 1000 grain, weight of grain per panicle and production per plot. The interaction significantly influence for plant height 2,3 and 6 weeks after planting (wap), numbers of tillers 2,5 and 6 wap, and weight of grain per panicle. The highest production variety was Ciherang 3,84 kilograms per areas (4,5 m²) and the lowest production was IR 64 variety 2,92 kilograms per areas.

Kacang tanah merupakan tanaman pangan yang memiliki nilai ekonomi dan kandungan lemak serta protein yang tinggi. Penelitian ini bertujuan meningkatkan pertumbuhan dan produksi kacang tanah (Arachis hypogea L.) dengan beberapa sistem olah tanah dan pemberian konsorsium mikroba. Penelitian dilakukan di lahan masyarakat, Kelurahan Mencirim, Kecamatan Binjai Timur, Kota Binjai, Sumatera Utara pada bulan Januari sampai dengan April 2016. Penelitian ini menggunakan rancangan petak terbagi (RPT), sebagai petak utama yaitu pengolahan tanah dengan 2 taraf; pengolahan tanah konservasi dan pengolahan tanah konvensional, anak petak yaitu aplikasi konsorsium mikroba dengan 4 taraf; 0, 6, 12, 18g/kg benih. Dari perlakuan tersebut terdapat 8 kombinasi perlakuan dan 3 ulangan. Hasil penelitian menunjukkan bahwa perlakuan pengolahan tanah, pemberian konsorsium mikroba, dan interaksi kedua perlakuan berpengaruh tidak nyata terhadap pertumbuhan dan produksi kacang tanah. Kata kunci : kacang tanah, konsorsium mikroba, pengolahan tanah.

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.
