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

Glasshouse experiment was conducted to study the effect of mycorrhizae inoculation and it's interaction with P supply on P leaf content and quality of oil palm seedling. Factorial experiment was arranged in Randomized Block Design with three replications. The first factor were mycorrhizae inoculation : without inoculation, mixed mycorrhizae, Acaulospora sp, Glomus manihotis, Glomus sp.1, Glomus sp. 2, Glomus sp. 3, The second factor were level of Roch Phosphate fertilizer : 0 g/seedling, 2 g/seedling, 4 g/seedling and 6 g/seedling. Mycorrhizae inoculation affected the P leaf content and percentage of infection significantly, Glomus sp decreased P leaf content. Acaulospora sp. gave the best quality of seedling, but Glomus sp. 3 gave the bad one. The Rock Phosphate application did not affect on P leaf content absorption efficiency and inoculation percentage due to high soil phosphorus content.

Abstract

The objective of research was to know effective concentration of surfactant and kind of herbicide. Research was conducted at young rubber plantation of PTPN VIII, Sukabumi, West Java. Factorial experiment was arranged in Randomized Block Design with three replication. The first factor was kind of herbicide, glyphosate 2.5 l/ha, sulphosat 1 .5 l/ha and paraquat 2 l/ha. The second factor was surfactant concentration of 0 %, 0.1 % and 0.2 %. Glyphosate that was mixed with 0.2 % of surfactant controlled weed at young rubber plantation effectively. It was showed by low persentage of weed covering. Paraquat without surfactant controlled Borreria alata, and Commelina benghalensis. Glyphosate without surfactant controlled Ottochloa nodosa and Ischaemumti morense.

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.
