Oil palm plantation expansion in Indonesia continue to increase year by year. Several varieties of oil palm have been produced but not much information about the growth characteristics. Urea as nitrogen fertilizer has become a staple for the cultivation cycle of oil palm. The determination of nitrogen use efficiency (NUE) on palm oil varieties can be used to find out N requirement of each plant according to their needs. This research was aimed to analyze the growth response and NUE of palm oil varieties to fertilizer N at pre nursery. It was conducted in nursery area at Yos Sudarso Binjai Street and Pusat Penelitian Kelapa Sawit, Medan from November 2016 until March 2017 using Completely Randomized Block Design followed by Scott Knott test at α = 5%. There were 35 treatment combinations that used seven varieties of Dura x Pisifera Medan Palm Oil Research Center (AVROS, Simalungun, PPKS 540, Yangambi, PPKS 718, PPKS 239, and Langkat) with N consisting of 5 levels (0 ; 0,5 g ; 1 g; 1.5 g and 2 g). The results showed that the application of N fertilizer influence significant effect on the growth of stem circumference and the number of leaves. The highest of nitrogen use efficiency is found in Simalungun varieties with N application of 1,5 g/plant.

Introduction: This study aims to obtain concentration of shallot extract (Allium cepa ) and growth regulators to increase growth of Mucuna bracteata. Mucuna is a land cover plant that must be planted in oil palm plantation areas. It is very important to be able to cover the planting area. Materials and Methods: This study used two factorial in randomized block design. The first was concentration of shallot extract per 100 ml distilled water consists of 4 levels, such as control (B0), 10 cc (B1), 20 cc (B2), 30 cc (B3) and the second was the auxins-plant growth regulator consists of 4 levels: Control (G0), 100 ppm (G1), 200 ppm (G2), 300 ppm (G3). Data analyzed with ANOVA with a significant 5% and continued with the DMRT using SAS version 9.1.3. Results: It was found that effect of concentration of shallot extract had a significant effect on survival percentage of Mucuna bracteata at a concentration of 10 cc (B2) after opening the lid at four weeks after planting (WAP) and did not change until 8 WAP. Likewise, the number of leaves at the control concentration (B0) at the age of 6 WAP, and a concentration of 10 cc (B1) at the age of 7-8 WAP. The concentration of growth regulators and their interactions did not significantly affect the survive percentage and number of leaves in Mucuna bracteata.

<p>Os consórcios feitos de forma adequada podem resultar em inúmeros benefícios ao agroecossistema e ao produtor. O objetivo foi avaliar aspectos fitotécnicos do rabanete e alface cultivados em consórcio no oeste goiano. Foram testados 4 consórcios (com 8 plantas de alface e 20, 40, 60 e 80 plantas de rabanete, respectivamente, C I, C II, C III e C IV) em relação ao monocultivo de alface (16 plantas) e de rabanete (80 plantas) por metro quadrado. O delineamento foi em blocos casualizados, com quatro repetições. Avaliou o diâmetro, comprimento e massa média das raízes do rabanete; o diâmetro médio do coleto, número de folhas e massa média da parte aérea das plantas de alface e a produtividade de ambas as culturas. Calculou-se o índice de equivalência de área (IEA). O consórcio não afetou o tamanho e peso médio das raízes do rabanete, entretanto, a produtividade do C I (0,46 kg.m<sup>-2</sup>) foi inferior ao C III (1,97 kg.m<sup>-2</sup>), C IV (2,25 kg.m<sup>-2</sup>) e ao monocultivo (2,05 kg.m<sup>-2</sup>). Para a cultura da alface, houve diferença estatística apenas na produtividade, que foi maior no sistema em monocultivo (2,84 kg.m<sup>-2</sup>). Somente o consórcio II (0,82) apresentou IEA inferior ao monocultivo (1,0). Os consórcios apresentam potencial de uso pelos horticultores da região.</p><p align="center"><strong><em>Agronomic performance of intercropping between radish and lettuce in West goiano</em></strong></p><p><strong>Abstract</strong><strong>: </strong>Intercropping properly executed can result in many benefits to the agroecosystem and the farmer.

Oil palm plantations in Indonesia are the largest one in the world, reaching 12.3 million hectares, around 46% are smallholders with very low productivity couse  income of oil palm farmers is very low. One effort to take over the problems is to develop an intercroping pattern of soybean- oilpalm  by trimming  the tips of the midribs of oil palm plants on thewider side of interspace of palm stand rows, to increase light interception accepted by soy bean  plant surfaces. This study used a randomized block design (RBD) arranged in factorial 4x3 with three replications. The first treatment is cutting the edge of the oil palm midrib, namely P1 = 50 cm, P2 = 100 cm, P3 =  150 cm. The second treatment was low light intensity tolerant soybean varieties, namely: V1 = Dena 1, V2 = Anjasmoro and V3 = Detam 1. Other actions were carried out according to generally accepted standards. To see the effect of treatment carried out the F test at the level of 5%, and continued with the HSD test at the level of 5% to see the difference among treatments. The results showed that a hope of developing soybean plants as intercrops, although statistically did not show a significant difference. FFB results were not significantly affected by the act of  trimming the midrib as 150 cm.

This study aims to determine the effect of the concentration of ultra gene liquid biofertilizers and crowns compound NPK and to find out whether there is any interaction between the both of it on the growth of oil palm seedlings.This research was carried out at the main nursery land of Nusantara I Plantation Limited Company (PTPN I) Kebun Baru, Langsa City, Aceh Province from June to September 2017. This study used factorial randomized block design with 16 treatments repeated 3 times. This study consisted of two factors, namely the dose of ultra gene liquid biofertilizer 0.100, 200 and 300 ml and the dose of crowns compound NPK fertilizer 0,5,10 and 15 g. The results showed that the dose of Ultra Gen liquid biofertilizer significantly affected the stem diameter, leaf number and leaf area in almost all MSP and significantly affected the leaf area of 6 MSP. The dose of Ultra Gen liquid biofertilizer treatment has a very significant effect on the growth of oil palm seedlings, which is indicated by the parameters of the increase in stem diameter, number of leaves and leaf area, and only a significant effect on leaf area 6 weeks after observation. The dose of 200 ml of the Ultra Gen factor shows better growth than other doses. There is a real interaction on seedling growth as indicated by the parameters of the number of seedlings. The highest number of seed leaves was shown by the treatment of 100 ml / polybag ultra gen with NPK 5g/polybag (U1N1), and 200 ml / polybag with no NPK fertilization (U2N0), although not significantly different from the U0N0 and U3N3 treatment combinations, but significantly different with the combination of other treatments.
