Abstract

The Persistence of Clomazone and Pendimethalin Herbicides in Soybean Cultivar of Argo MulyoABSTRACT. A field research has been conducted in PT. Syngenta RD Station Cikampek, Karawang to investigate the persistence of clomazone and pendimethalin herbicides in soybean cultivar of Argo Mulyo. The dosage of clomazone and pendimethalin herbicides used were: 0.75; 1.50; and 2.25 kg a.i. ha-1. The persistence of clomazone and pendimethalin herbicide varied from 28 to 96 days and 43 to 75 days, respectively. The persistence of clomazone herbicide was longer than the of pendimethalin.

Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengetahui pengaruh dosis pupuk N dan P serta media tanam terhadap pertumbuhan dan hasil tanaman kacang tanah. Ada 2 faktor yang diteliti yaitu dosis pupuk N dan P terdiri dari 4 taraf: tanpa pupuk, 0,21 + 0,21, 0,26 + 0,32, dan 0,32 + 0,42 g/pot. Faktor media tanam terdiri atas 3 taraf yaitu: tanah Entisol tidak tercemar tanpa isolat bakteri, tanah Entisol tercemar tanpa isolat bakteri dan tanah Entisol tercemar diberi isolat bakteri. Peubah yang diamati yaitu tinggi tanaman, diameter pangkal batang, jumlah polong, berat polong dan jumlah polong bernas pertanaman, berat basah dan kering berangkasan tunas, berat basah dan kering berangkasan akar. Hasil penelitian menunjukkan bahwa pertumbuhan tanaman kacang tanah terbaik dijumpai pada perlakuan dosis pupuk N dan P 0,32 + 0,42 g/pot (90 kg urea + 120 kg SP36/ha). Selanjutnya pertumbuhan dan hasil tanaman kacang tanah terbaik dijumpai pada media tanam tanah entisol tidak tercemar tanpa isolat bakteri. Pertumbuhan dan hasil kacang tanah pada tanah tercemar hidrokarbon diberi isolat bakteri lebih baik bila dibandingkan dengan tanah tercemar hidrokarbon tanpa isolat bakteri. The Growth and Yield of Peanut (Arachis hypogeal L.) by Affected Nitrogen and Phospate Fertilizers on Growing Media of Hydrocarbon ContaminatedABSTRACT. This study aims to determine the effect of N and P fertilizers and growing media on the growth and yield of peanut plants. There are 2 factors studied were N and P fertilizer consists of 4 levels : no fertilizer , 0.21 + 0.21 , 0.26 + 0.32 and 0.32 + 0.42 g / pot. Factors planting medium consisting of 3 levels: Entisol uncontaminated soil without bacterial isolates, entisols contaminated soil without bacterial isolates and soil contaminated Entisol given bacterial isolates. Parameters observed that the plant height, stem diameter, number of pods , pod weight and number of pods pithy planting, wet and dry weight of shoots, wet and dry weight of roots. The results showed that the best peanut plant growth observed in the treatment of N and P fertilizer dose of 0.32 + 0.42 g / pot ( 90 kg urea + 120 kg SP36/ha). Furthermore, growth and yield of peanut plants best observed in growing media entisols uncontaminated soil without bacterial isolates. Growth and yield of hydrocarbon contaminated peanuts given bacterial isolates better when compared with hydrocarbon contaminated soil without bacterial isolates.

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.
