Abstract

Ketersediaan air untuk tanaman dapat dipertahankan dengan pemberian irigasi dan penggunaan mulsa. Penelitian ini dilakukan untuk mendapatkan volume irigasi pada berbagai jenis mulsa yang efisien untuk tanaman bawang merah varietas Bima Brebes. Rancangan penelitian tersusun secara acak kelompok dengan dua faktor dan tiga ulangan. Faktor pertama adalah tingkat volume irigasi berdasarkan evaporasi panci (Eo) yang terdiri dari 6 taraf yaitu 0.25 Eo, 0.50 Eo, 0.75 Eo, 1.00 Eo, 1.25 Eo, dan 1.50 Eo. Faktor kedua adalah jenis mulsa yang terdiri dari 3 taraf yaitu tanpa mulsa, mulsa plastik hitam perak, dan mulsa jerami. Interaksi antara volume irigasi dan jenis mulsa meningkatkan pertumbuhan tinggi tanaman, jumlah daun, jumlah anakan, volume akar, jumlah akar, bobot kering, diameter umbi, dan bobot basah umbi per rumpun. Kombinasi volume irigasi 1.50 Eo dengan mulsa plastik menghasilkan bobot basah umbi tertinggi dan tidak berbeda nyata dengan volume irigasi 0.50 Eo dan 0.75 Eo pada mulsa plastik serta volume irigasi 1.00 Eo dan 1.50 Eo tanpa pemberian mulsa. Kombinasi volume irigasi 0.50 Eo dengan pemakaian mulsa plastik direkomendasikan untuk alasan efisiensi pemakaian air dan penggunaan air yang lebih sedikit. Kata kunci: diameter umbi, evaporasi, mulsa plastik plastik hitam perak, mulsa jerami

Abstract

The objective of this research was to study the effect of irrigation system on production and organoleptic quality of tobacco. The treatments were conventional irrigation, drip irrigation with mulch and drip irrigation without mulch.  Conventional irrigation was the irrigation system that was usually applied by farmer.  Plastic pipe was used for conveying water from water resource to field, and the irrigation was given twice a week. Drip irrigation was given once in two days. Drip irrigation with mulch resulted higher sun cured leaf weight and water used efficiency than conventional irrigation, but it was not significantly different compared with drip irrigation without mulch.  Drip irrigation without mulch resulted 5.505 ton/ha of sun cured leaf and water use efficiency as much as 3.4 g of sun cured leaf/kg of water.  Organoleptic quality resulted by three irrigation systems were mild to medium, fairly smooth and low irritant.   Key words :  Drip irrigation, mulch, water use efficiency, organoleptic quality, tobacco

Abstract

Dioscorea was a member of Dioscoreaceae, ordo of liliales and class of Monocotyledoneae, Two types of Dioscorea were annual and perennial. As much as 50-60 species of 600 species was cultivated as food source. This research was conducted to study tuber characters and nutrition content of Dioscorea sp. Plant material was Dioscorea collection from some places in Indonesia. Five accessions of Dioscorea alata. Dioscorea esculenta and Dioscorea hispida. were analyzed for the content of fat, protein and starch. Tube characters observed were tuber number, tuber weight, length and diameter. There were significant differences of tube character, protein and starch content between Dioscorea accession. The highest tuber weight and starch content were resulted by D.alata especially accession number 49. The highest protein content was resulted by accession number 67 of D. esculenta. Positive correlation between tuber diameter and tuber weight of D. alata showed that higher accumulation of fotosynthate was followed by increasing tuber diameter. In other words, sink capacity was determined by tuber diameter. Key words: Tuber, Dioscorea spp., Nutrition content

Abstract

The research was conducted to study the correlation between deficit of evapotranspiration and yield decreasing.   Factorial experiment was arranged in Randomized Block Design.  First factor was irrigation frequency of 1, 2, 4 and 6 days.  Second factor were nine upland rice lines.  Evapotranspiration was measured with simple lysimeter based on water balance. There was positive correlation between deficit of evapotranspiration and yield decreasing. Defisit of evapotranspiration as much as 240.06 mm caused yield decreasing of 90% and dry matter weight decreasing of 72.5%. The relation between total evapotranspiration (E, mm) and dry matter weight (DM, g/plant) was DM = 0.0245 E + 13.85.  Water use efficiency or yield and evapotranspiration ratio correlated with leaf width and sum of seed each panicle  positively .  Increasing leaf width and sum of seed each panicle could increase water use efficiency.    Key Words : evapotranspiration, water use efficiency, upland rice, lysimeter.

Abstract

This experiment was aimed to study the effect of tap root length and storage duration on growth of Sengon stump. The field experiment was carried out as a two factors factorial experiment. The treatments were arranged in Randomized Block Design with three replications. The tap root length of 25 %, 50 %, 75 %, and 100 % of original tap root length were the levels of first factor. The storage duration 0 hours, 24 hours, 48 hours, 72 hours, and 92 hours after revoking were the levels of second factor. The tap root length affected shoot to root ratio. The least damage root gave the lowest shoot to root ratio. The root length 25 % gave the highest shoot to root ratio, but the difference between 50 %, 75 %, and 100 % were not significant. At 18 weeks after planting, the shoot diameter, shoot height, leaf number, shoot dry weight and root dry weight were not affected by tap root length and storage duration after revoking. Interaction between two factors did not effect all of the observed variables.

Abstract

The research was conducted to investigate the effect of copper (Cu) levels in irrigation water on the growth and production of rice variety IR64. The experiment was arranged in randomized complete block design with six replications. The Cu treatments were: 0, 300, 600 and 900 mg Cu L-1of irrigation water. The results showed that Cu content significantly decreased rice growth and production. Copper level of 600 mg L-1 decreased plant height, tiller number and leaf number. Copper level of 300 mg L-1 decreased panicle length, number of grains per panicle, empty grain weight, 100 grains weight, milled grain weight, and shoot dry weight. This experiment implies that remediation treatments should be considered when Cu level in irrigation water was more than 300 mg Cu L-1. Copper level of 300 mg L-1 could be used as a critical level for rice screening for Cu tolerant varieties in the plant breeding program. Keywords: copper toxicity, low land rice, rice growth and production, water quality
