Abstract

The Effect of Spacing Between Rows of Several Varieties of Sweet Corn and Kidney Beans Growth and Yield for Intercropping SystemABSTRACT. The research was to find the effect of  planting distance and some varieties on intercropping system of sweet corn and kidney beans to improve growth and   yield.  The experimental design was Complete Block Randomized with two factors and two replications. The first factor was planting distance between rows of sweet corn intercropping system (J1=60cmx30cm; J2=80cmx30cm; J3=100cmx30cm).  Then the second factor was variety (V1= Kumala F1; V2= King Sweet F1; V3=Super Bee). The results indicated that the best planting distance on intercropping some varieties of sweet corn and kidney bean was 100cmx30cm for sweet corn and 80cmx30cm and 100cmx30cm for kidney bean. The varieties treatment showed that the best variety of sweet corn was Super Bee and kidney bean was King Sweet F1. There was significantly different interaction between planting distance and varieties on intercropping system of sweet and kidney bean on the corn husk weight of sweet corn.

Abstract

Land evaluation is the process of estimation of the potential of the land for a variety of alternative uses. Land evaluation involves conducting a survey or research shapes the landscape, nature and distribution of land, and the distribution of vegetation types and aspects of other land. This research aims to determine the level of suitability for irrigated rice in Air Hitam                             Village Lima Puluh District Batubara Regency. This research was conducted in                                    Air Hitam Village Lima Puluh District Batubara Regency and Technology Laboratory                           of  Agriculture Faculty in May 2011 - April 2012. This research uses the method of limits                refers to the level of the limiting factors of land characteristics. The data observed in the               field (the physical environment) and the data matched the results of laboratory analysis            (matching) with the criteria of suitability class irrigated rice land. The results showed that the limiting factor on irrigated land is soil depth, soil texture, and base saturation.

Abstract

Rice and Watermelon cropping pattern has been always applied at Air Hitam Village, Lima PuluhSubdistrict, Batu Bara District. The selected cropping pattern was choosed because of rice productiondid not increase in rice and rice cropping pattern, and it will be expected that rice and watermeloncropping pattern will increase the farmer income. The difference in cropping pattern and supply oforganic matter changes in soil properties of fields. The objective of this study was to know the changesin some chemical properties of paddy soil at Air Hitam Village, Lima Puluh Subdistrict, Batu BaraDistrict which is lacated at about 18 m above sea level (asl). Parameters measured were pH usingElectrometric method, organic carbon by using Walkley and Black method, available phosphorus byusing Bray II method, exchangeable potassium NH4OAc with method, total-N by using Kjeldahl methodand available SiO2 by using ammonium acetate extraction. The results of this study showed that rice andwatermelon cropping pattern didn’t affect the paddy soil chemical properties including pH, organiccarbon, total-N, available phosphorus, and exchangeable potassium, except soil available SiO2, is higherat rice and watermelon cropping pattern compared to that rice-rice cropping pattern.Key words : cropping system, soil chemical properties.

Hasil Penelitian menunjukkan bahwa, perlakuan urea memberikan pengaruh sangat nyata terhadap tinggi tanaman umur 30 HST dan 45 HST,  gabah per plot,  dan memberikan pengaruh nyata terhadap jumlah anakan umur 30 HST. Perlakuan arang aktif memberikan pengaruh nyata terhadap jumlah anakan padi umur 30 HST dan berat gabah per plot sedangkan zeolit berpengaruh terhadap jumlah anakan padi umur 30 HST. Terjadi Interaksi yang nyata antara ; urea dan arang aktif terhadap jumlah anakan umur 15 HST ; urea, arang aktif dan zeolit terhadap jumlah anakan umur 30 HST ; arang aktif dan zeolit terhadap jumlah anakan produktif.Effect of Urea, Active Charcoal, and Zeolite on Growth and Yield of Rice(Oryza sativa L.)ABSTRACT. The objectives of the research were to study effects of urea, active charcoal and zeolite on growth and yield of rice. The experiment was arranged in a factorial randomized block design with three replications. Factor of urea consisted of three levels, i.e. treatment without urea, urea 150 kg ha-1 and urea 200 kg ha-1. Factor of active charcoal consisted of two levels i.e. treatment without active charcoal and active charcoal 40 kg ha-1. Factor of zeolite consisted of two levels i.e. without zeolite and zeolite 200 kg ha-1. Results showed that urea exerted  highly significant effects on plant height at age 30 days after transplanting (DAT) and 45 DAT, grain per plot, and exerted a significant effect on tiller numbers at 30 DAT. Active charcoal exerted  significant effects on tiller numbers at 30 DAT and grain weight per plot, while zeolite exerted significant effect on tiller numbers at age 30 DAT. Significant interaction occurred between urea and active charcoal on tiller numbers at age 15 DAT; urea, activated carbon, and zeolite on tiller number at age 30 DAT; active charcoal and zeolite on productive tiller numbers.

Abstract

Konsepsi tentang perempuan adalah salah satu isu yang paling sering dibicarakan  khususnya diantara berbagai konsepsi sosial yang ada. Salah satu isu yang berkaitan dengan perempuan yang sering dibahas adalah poligami yang menimbulkan berbagai respon yang berbeda dari berbagai pihak dalam menyikapi isu tersebut. Perdebatan panjang tentang praktek poligami di masyarakat berdasar pada legalitas poligami dan dampaknya terhadap perempuan. Praktek poligami juga menarik perhatian banyak kalangan terutama ketika terjadi pro dan kontra. Bagi kelompok yang berpihak pada praktek poligami selalu berusaha mengemas alasan klise untuk mendukung argumen mereka. Sebaliknya, bagi kelompok yang menyuarakan isu-isu gender dan perempuan terus membangun argumen yang berusaha membuktikan bahwa poligami berpeluang untuk memberikan dampak yang negatif bagi perempuan. Terlepas dari kedua kutub tersebut, poligami merupakan suatu isu yang terus mengabadi sebagai wacana yang bersifat polemis yang nampaknya tidak mudah untuk berujung pada suatu kesepakatan dalam tataran konsep dan realitas.
