Abstract

ABSTRACTChili grows well both in lowland and highland, and as a high economic vegetable chili is widely grown by farmers. Nevertheless, there are still many obstacle in its management among others is pest and disease attack. Antracnose disease by Colletotrichum sp. causes yield decrease even harvest failure as it attacks the fruits. The objective was to find out kinds of biopesticides and its concentration to control antracnose disease. The experiment was conducted in Faculty of Agriculture garden from July until February 2017. A Randomized Block Design was used consisted of 9 treatments i.e. A (control), B (1% soursop extract), C (2% soursop extract), D (1% siam weed extract), E (2% siam weed extract), F (1% galangal rhizome extract), G (2% galangal rhizome extract), H (1% mixture of soursop, kirinyuh, and galangal rhizome extract), and I (2% mixture of soursop, siam weed, and galangal rhizome extract). The results that the efficacy of application of 1% to 2% extracts of soursop leaf, siam weeds, and galangal rhizome, both independently and in mixture, were in the range of ineffective and less effective categories in controlling antracnose disease on red chilli.

Abstract

The purpose of this study was to  determine the accuracy of the method of long width method for measurement of corn leaf area (Zea mays L.) and soybean (Glycine max L) compared to method of leaf area meter. This study use  designed by comparing the two methods, then the statistical test was done with the t-test. The result of this study showeed  that correction factor (k) of leaf area length method obtained with Agustina (1988) version is not significantly different from Sitompul and Guritno version (1995). The k values used in the calculation of the leaf area with the long-width method of Sitompul & Guritno's (1995) version can be used at any age of observation on both corn and soybean crops, for Agustina (1988) the k value on corn leaves can be used every age of observation, but in soybean crop needs to be made a new k value at the age of the plant further (eg 5 MST) with the number of leaves more. The accuracy of the long-width method for measuring leaf area in maize compared with LAM method is quite high, Sitompul & Guritno (1995) version reaches 100% and Agustina's version is slightly lower that is 75%. The accuracy of Sitompul & Guritno (1995) and Agustina (1988) long-range method for measuring leaf area on soybean crops compared with very low LAM method is 25%. The accuracy of the method of length method times compared to LAM method toward measurement of corn leaf area is higher than in soybean crop Keywords: Leaf area, of corn and soybean leaf, Length method times width, Leaves

Abstract

ABSTRACTCocoa (Theobroma cacao L.) is one of the large plantations after oil palm. Theincrease in cocoa nursery can be accompanied by the utilization of waste derivedfrom palm oil, namely oil palm empty fruit bunches (OPEFB). oil palm emptyfruit bunches can be useful as organic fertilizer because it can improve soilphysical, chemical and biological properties. The use of OPEFB as organic fertilizer will also reduce excessive use of NPK. Utilization of OPEFB into organic fertilizer can be in the form of compost or raw OPEFB organic matter plus cellulolytic and lignolytic microbes. This study aims to determine the effectof NPK fertilizer and OPEFB compost on the growth of cocoa seedlings. Thisresearch was conducted experimentally using a completely randomized designconsisting of nine treatments and three replications. Parameters of observationwere plant height, stem diameter, number of leaves, root canopy ratio, dry weight of seedlings and age of planting. The results showed that the provision of 100 g polybag-1 OPEFB compost plus 50% NPK fertilizer (2 g polybag-1) could provide good growth in cocoa seeds (Theobroma cacao L.).
