Abstract

Weed-Crop Growth Analysis and Yield of Corn with Groundnut and Mungbean of Varying Plant Population in Intercropping SystemABSTRACT. The present experiment is designed to evaluated the weed-crop growth of intercrop between corn with mungbean and groundnut of varying plant populations. The experimental used the single factor field experiment that arranged with randomized completely block design with three block as replication. Intercropping followed additive series system, i.e.: (A) corn 100% + mungbean 25%, (B) corn 100% + mungbean 50%, (C) corn 100% + mungbean 75%, (D) corn 100% + groundnut 25%, corn 100% + groundnut 50%, (F) corn 100% + groundnut 75%. Experimental result showed that: Intercropping corn with groundnut and mungbean of able to weed growth suppressed of sedges, and Intercropping crop with groundnut at 75% rate of recommended population weed growth suppressed of total weeds compared to the other three mungbean populations. Intercropping corn with groundnut at 25% of recommended rate gave the highest sweet corn yield per hectare.

Abstract

Effect of Inoculation of Indegenous Population of Arbuscular Mycorrhiza Fungi and Tillage Systems of Mycorrhiza Effectiveness, Yield Components, and Yield of Upland Rice (Oryza sativa L.) on UltisolsABSTRACT. The field experiment was conducted to study the growth characteristics, agronomy characteristics, and yield of upland rice on ultisols with various dosages of AMF inoculants on three tillage systems. The experiment was carried out Kampung Baru village, Bandar Lampung City from April until August 2005. The experiment used a spilt plot pattern in randomized block design. The main plot was soil tillage systems with consisted of three levels, those were intensive tillage, minimum tillage, and no tillage; and sub plot was AMF inoculants dosages with consisted of four levels, those were 0, 6.0, 13.0, and 19.50 ton ha-1. The result of experiment showed that tillage systems and AMF inoculants affected produces the highest yield for rice, and this yield depend on tillage systems. The highest yield of rice was 3,559.03 g 8m-2 obtained of optimum dosage 13 ton ha-1 AMF inoculants in minimum tillage.

Abstract

Root Growth, Development and Yield of Mungbean in Various Soil Tillage Systems on Irrigated Low Land Fertilized by PABSTRACT. The experiment was carried out to observe root growth and development, and yield of mungbean (Vigna radiata (L.) Wilczek) on irrigated low land as a result of P dosages application and various soil tillage systems. Field experiment was carried out at Kedaloman village, Tanggamus regency of Lampung Province. Field experiment used a split plot pattern in randomized block design. The main plot were soil tillage systems which consisted of tree levels, those were intensive tillage, maximum tillage and no-tillage; and subplot was P dosages which consisted of four levels, those were 0, 9.9, 19.8, and 29.7 kg ha-1 P. The experiment result showed that soil tillage system had no significant effect on length and number of root, volume of root nodule. The highest yield of dry grain was 1.545,1729 g (1,9315 ton ha-1) obtained at optimum dosage 18,0740 kg ha-1 P.

Abstract

Effect Inoculation of Indigenous Population of Arbuscular Mycorrhiza Fungi and Dosage of Mulch on Mycorrhiza Effectiveness and Agronomy Characteristics of Upland Rice (Oryza sativa L.) in Green HouseABSTRACT. The experiment was conducted to study agronomy characteristics and mycorrhiza effectiveness of upland rice in green house with various levels of AMF inoculants and mulch dosage application. The pot of experiment was carried out in the green house of Agricultural Faculty, The University of Lampung from October 2004 untill February 2005. The experiment used randomized complit block design arranged in factorial pattern with two factors. The first factor was dosages of mulch (0, 5, 10, and 15 ton ha-1) and the second factor was AMF inoculants dosages which consist of four levels, those were 0, 25, 50, and 75 g pot-1. The result of this experiment showed that dosages of mulch and AMF inoculants affect to agronomy characteristics and mycorrhiza effectiveness of upland rice in the green house. Up to the certain dosages, inoculants of AMF and mulch raised P content in plant, shoot dry weight, root dry weight, harvest index, and mycorrhiza effectiveness.
