Abstract

Laboratory bioassays were conducted to compare the effects of the leaf extract of Acalypha indica  L. (Euphorbiaceae) with synthetic insect growth regulators (IGRs) triflumuron and buprofezin against Spodoptera litura (F.). The experiment was set up as a randomized complete block design (RCBD). The treatments were two concentrations of  A. indica extracts 1000 and 2000 ppm, two concentrations of  buprofezin 100 and 200 ppm, two  concentrations of triflumuron 120 and 240 ppm and control. Each treatment was replicated three times. Second instar larva of  S. litura  were used for the bioassays.  Mortality and biological variables of treated and control larvae were recorded daily. The results indicated that the application of A. indica extracts  and synthetic IGRs (buprofezin & triflumuron) significantly caused the S. litura  mortality throughout the experimental period. At first, the toxicity of triflumuron on larval S. litura was significantly higher compared to those of buprofezin and Acalypha indica leaf extract. However, at the end of experimental period all treatments caused high mortality on S. litura, and those all were significantly different from control. The treatments also caused abnorrmal growth in larval, pupal, and adult stages. While in the control, larvae molted into normal adults. The results indicated that the use of biorational control agents such as synthetic insect growth regulators (IGRs) and those based on naturally derived products such as botanical insecticides show promise as a potential tool in S. litura management programs.

Abstract

Peningkatan produksi tebu banyak terkendala seperti rendahnya bahan organik dan hara makro N, P, K, Ca, dan Mg di tanah ultisol.  Karena di tanah ultisol kandungan kadar Al3+ yang cukup tinggi, dan kejenuhan basa yang rendah.  Penambahan pupuk organonitrofos dan anorganik merupakan salah satu cara untuk mengatasi hal ini.  Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi pupuk organonitrofos dan pupuk NPK terhadap produksi, populasi, dan hara terangkut dan hara terangkut tanaman tebu ratoon 2, dan korelasi antara N-total tanah dan P-tersedia tanah dengan N dan P yang diserap oleh tanaman tebu ratoon 2.  Penelitian ini terdiri  5 perlakuan dan 3 ulangan, disusun dalam Rancangan Acak kelompok (RAK).  Perlakuan terdiri dari: A. 100% NPK (300 kg ha-1 urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl), B. 100% organonitofos (10.000 kg ha-1 organonitrofos), C. 100% NPK + 50% organonitrofos (300 kg ha-1 urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl, 5000 kg ha-1 organonitrofos), D.50% NPK + 100% organonitrofos (150 kg ha-1 urea,  75 kg ha-1 TSP, 150 kg ha-1 KCl, 10.000 kg ha-1 organonitrofos), dan  E. tanpa pemupukan.  Hasil penelitian menunjukkan bahwa Pemberian pupuk anorganik NPK, pupuk organonitrofos dan kombinasi berpengaruh nyata terhadap produksi dan hara terangkut C, N, P tanaman tebu ratoon 2, namun tidak berpengaruh nyata terhadap populasi tanaman tebu ratoon 2. Pemberian 100% NPK, 50% NPK + 100% organonitrofos 100% NPK +50% organonitrofos dan memberikan produksi dan hara terangkut C, N, P tanaman tebu yang tidak berbeda nyata, namun nyata lebih tinggi dibandingkan dengan perlakuan 100% organonitrofos dan tanpa pemupukan. Korelasi positif  N-total tanah dan P-tersedia dengan N dan P yang diserap oleh tanaman tebu ratoon 2, sehingga kandungan N-total tanah dan P-tersedia tanah menentukan jumlah N dan P yang dapat diserap oleh tanaman tebu ratoon 2.

Abstract

Rampai tomato (Lycopersicon pimpinellifolium) is one important vegetable in Indonesia.  The production of rampai tomato increases every year, indicating a good opportunity for the tomato  in market. In the process of cultivation, fertilization is a very important aspect.  Advances in technology have invented some importantagricultural inputsespecially for chemical fertilizers such as Urea, TSP, KCl, NPK, and others.  Nowadays, small scaled farmers frequently face difficulty to get chemical fertilizers on market because ofeither scarcity or high price.  This condition needs to be well anticipated.  Reducing the use of chemical fertilizers by using organic fertilizers which isproduced from local and cheap natural resources is a somewhat promising solution.The organic fertilizer tested in this study is an alternative fertilizer called Organonitrofos.  Organonitrofos fertilizer is made from 70-80% cow dung and 20-30% phosphate rock, in the previous research.  Both the materials are locally available in Lampung.  This fertilizer then needs to be tested to ensureits consistency on plant production.  In this study, Organonitrofosfertilizerwas testedon rampai tomato plantsin pots (pot experiment).The study aimed  (1) to test the Organonitrofos fertilizer on the response of rampai tomato plants in pots (2)reduce the useof chemicalfertilizersin the production oframpai tomatoplants.The pot experiment was conducted in the Integrated Field Laboratory of the Faculty of Agriculture University of Lampung on January - April 2012.  The experiment used Completely Randomized Design (CR) with 7 treatment (7 combinations between chemical fertilizer and Organonitrofos), 4 replicates each.  Data collected was analyzed by using ANOVA and followed by LSD.  The variables observed were agronomic aspects (such as plant height, biomass, and production) and water consumption.  The results showedthat,based on theplant responsevariablessuch asplant height, upper and biomasses, andcrop production, treatmentC(100% Organonitrofos with 5000 kg/ha dose) was significantly different and better from every other treatment. Based on the water consumption (evaporationand irrigation), all the treatments were not significantly different.  However, the research showed that the use of 100% Organonitrofos fertilizer (5000 kg/ha); resulted in the highest water productivity (yield/water consumption).  This research also showed that the use of chemical fertilizersbe could significantly reduced by using combination between chemical fertilizers and Organonitrofos. Keywords: Rampai tomato , fertilizer, organonitrofos, plants response.
