Abstract

The objective of this research was to study the change of vegetative growth of root on some genotypes soybeanof aluminium toxicity, drought stress, and double stress (Al toxicity and drought stress). Research in rooting systemof soybean is hoped to get more attention, especially for supporting concept of new plant type for high yieldingpotential. Six genotypes of soybean (Slamet, Sindoro, Dieng, Sinyonya, Lumut, and Wilis), treated with aluminiumsaturated (Al 25%, Al 50%, and Al 75%) and field capacity (80% FC and 40% FC). Response of growth vegetativeidentified perception by root dry weight. Result of the study show that only one from six that is genotype Wiliswas tolerant at aluminium toxicity, drought stress, and double stress.

Abstract

Water availability is a major factor affecting rice production especially in upland.  The Production of upland rice is low because of the low of  water availability in upland.  Roots play an important role in upland rice adaptation to drought conditions. This study aimed to identify the characteristic of upland rice variety root development under  soil moisture gradients. This study use  randomized  factorial design consisting of 2 factors and 3 replicate.  Factor I : 12 upland rice variety, ie: Silumut, Batutegi, Limboto, Situpatenggang, Situbagendit, Towuti, Cirata,  Danau Gaung, Gajah Mungkur, Inpago 4, Inpago 5, Inpago 6. Factor II :  gradien of soil moisture level, ie: 20 %, 40 %, 60 %, 80 % field capacity. The Result of research indicate all the upland rice variety were classified tolerance based on relative value of root leght. The highest root lenght and the heaviest root dry matter were generally from combination uplandrice varieties with 60 80 % field capacity except Inpago 4 and Situbagendit showed  the highest root lenght at 20 % field capacity and combination The heaviest root dry matter at 40 %were Inpago 4 and Jatiluhur generally from characteristic of  root gro field capacity

Growth Response of Soybean with Mycorrizal Inoculation at Critical Condition of Aluminium and Draying DoubleABSTRACT. High level of aluminium in acid soil can restrict nutrient and water. Arbuscular Mycorrhizal Fungi (AMF) have been shown to decrease plant yield losses in acid soil. The objective of this study was to examine the growth responses of green house-grown soy bean colonization by AMF. The experiment was conducted at Cikabayan experimental of Bogor Agricultural University from August 2003 to February 2004. Six genotypes soy bean that result of root bioassay treated by Al by saturated (Al 25 %, Al 50 %, and Al 75 %), field capacity (80 % and 40 % FC) and Inoculated by mycorrhizae (without AMF and by AMF). Root and shoot dry matter were higher in mycorrhizal than in non mycorrhizal plants.

Abstract

ABSTRAKKedelai adalah tanaman yang membutuhkan fosfor (P) lebih banyak untuk pembentukan bijinya dibandingkan denganleguminosa lain. Fosfor merupakan faktor pembatas utama di daerah tropis karena sering difiksasi oleh aluminium danbesi. Salah satu upaya meningkatkan kesuburan tanah adalah melalui penambahan bahan organik dan manajemen fosfor.Tujuan penelitian ini adalah untuk mempelajari pengaruh pupuk organik dan fosfor terhadap pertumbuhan, hasil dan mutubiji kedelai. Percobaan dilakukan mulai April sampai September 2011 berupa percobaan pot (isi 10 kg tanah kering udara)menggunakan rancangan kelompok lengkap teracak dua faktor. Faktor pertama adalah pupuk organik yang terdiri atas tigajenis, yaitu kotoran sapi, tandan kosong kelapa sawit (TKKS), dan blotong, masing-masing dengan dosis 180 g tanamandan  tanpa  pupuk (kontrol).  Faktor  ke-2  adalah dosis P yang terdiri atas 4 taraf, yaitu 0, 0.45, 0.90, dan 1.35 g Ptanaman. Pupuk P tidak berpengaruh nyata pada seluruh peubah amatan, sedangkan pupuk organik berpengaruh nyata.Kompos blotong meningkatkan jumlah bintil akar efektif (77.0%), bobot kering akar (94.7% ), bobot kering  biji (50.3%),dan  kandungan protein biji (0.9%) dibandingkan tanpa pemberian. Kandungan lemak biji kedelai meningkat 4.2% denganpemberian blotong atau TKKS. Bobot kering tajuk tertinggi diperoleh pada pemberian kompos blotong dan pupuk P dengandosis 0.45 g tanaman-1-1.Kata kunci: blotong, Glycine max, kotoran sapi, tandan kosong kelapa sawit, lemak kedelai, protein kedelai

Abstract

Sugarcane (Saccharum officinarum.L) is the main material in sugar industry. An effort to improve the quality of dry land for sugarcane cultivation is important. One of the effort than can be done is the additional of organic metter to the soil. The objective of this research was to determine the effect of vertical mulching techniques for soil organic matter content and soil chemistry fertility and its relationship with the vegetative growth of the ratoon sugarcane. This research was conducted at Agricultural High School Practice (STPP) Medan-Binjai KM.10 districts Sunggal Deli Serdang, North Sumatra, from May -December 2013. This study was conducted using a randomized block design non factorial with four treatments, were: horizontal mulch (M1), vertical mulch (M2), vertical mulch with Trichoderma sp. (M3), Vertical mulch mixed with cow manure (M4). The result from the research showed, that vertical mulch mixture with manure can increase the level of C-organic, N-content, and the lower of Ratio C/ N . Vertical mulching treatment mix with manure, increasing the shoot length of sugarcane 21.9%, the number of plants per clump 6.8%, the number of plants per meter 50%, wet weight 68.28% and dry weight 41.9%, compared with horizontal mulch.Key words: sugarcane ratoon, mulch vertical, horizontal mulch, soil fertility

Abstract

The spesies composition of arthropods on agro-ecosystem can be seen as a general indicator for ecosystem stability and ecological resilience. Agricultural intensification has been linked with losses of biodiversity and disruption of key ecosystem services in farmed landscapes. This study aimed to determine how cropping system and farming systems able to increase the diversity of insects on potato field, that can be used as an integrated pest management strategy. The result showed that insect diversity index and population of natural enemies in polyculture cropping system is higher than monoculture cropping system, while the pest population is lower. Insect diversity index and population of natural enemies in organic farming systems is higher than conventional farming systems, in general the pest population was lower in conventional farming systems, but not significant with organic farming system. The polyculture cropping potatoes+cabbage+mustard+celery, potatoes+cabbage, potato+mustard respectively which grown by organic farming systems provide the highest insect diversity index, the lowest percentage of crop damage, the lowest populations of pest, and the highest natural enemy populations when compared with the same polyculture cropping with conventional farming systems. Keywords: Cropping system; farming system; insect diversity; potato

Abstract

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.
