[GROWTH AND LETTUCE YIELD (Lactuca sativa L.) BY GIVING MANURE AND RICE HUSK ASH IN INCEPTISOL]. Increasing market demand for lettuce (Lactuca sativa L.) makes the prospect of developing lettuce very promising. Bengkulu Province is dominated by inceptisol soil types which have low soil fertility, making it less optimal for lettuce growth. Giving organic matter can increase soil fertility through improving soil physical, chemical and biological properties so that it can support the growth of lettuce. This study aims to determine the dosage of manure, the dose of rice husk ash and the optimal dose interaction for lettuce growth and yield. This research was conducted from May 2018 to July 2018 in Medan Baru, Muara Bangkahulu Subdistrict, Bengkulu City. The research design used was a Completely Randomized Design (CRD) consisting of two factors and repeated 3 times. The first factor is the dosage of cow manure with three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha. The second factor is the dose of rice husk ash which consists of three levels, namely 0 tons/ha, 3 tons/ha, and 6 tons/ha. Data from the observations were analyzed statistically by Analysis of Variance (ANOVA) using the F test at the level of 5%. To determine the dosage of manure, the dose of rice husk ash and the optimal combination of doses for growth and yield of lettuce used the Polynomial Orthogonal method. The results showed that there was no interaction between cow manure and rice husk ash on the growth and yield of lettuce. The effect of cow manure has not shown the optimum dose for growth and yield of lettuce. The addition of manure doses up to 30 tons/ha was able to increase the value of plant height, number of leaves, leaf area, and fresh weighted plant weight of 0.189, 0.038, 0.931 and 0.104 respectively. Giving rice husk ash up to a dose of 6 tons/ha did not have a significant effect on all observed variables.
生长和莴苣产量(Lactuca sativa L.)用粪肥和稻壳灰混合。市场对生菜需求的增加使得生菜的发展前景十分广阔。明古鲁省以土壤肥力较低的土壤类型为主，使其不适合生菜生长。给予有机质可以通过改善土壤的物理、化学和生物特性来提高土壤肥力，从而支持生菜的生长。本研究旨在确定肥料用量、稻壳灰用量及其对生菜生长和产量的最佳交互作用。本研究于2018年5月至2018年7月在明库鲁市Muara Bangkahulu街道的Medan Baru进行。研究设计采用完全随机设计(CRD)，由两个因素组成，重复3次。第一个因素是牛粪的投加量，有3个等级，分别是0吨/公顷、15吨/公顷和30吨/公顷。二是稻壳灰分0吨/公顷、3吨/公顷、6吨/公顷三个层次施用。观察数据采用方差分析(ANOVA)，在5%的水平上使用F检验进行统计学分析。采用多项式正交法确定肥料用量、稻壳灰用量及对生菜生长和产量的最佳用量组合。结果表明，牛粪与稻壳灰对生菜的生长和产量没有交互作用。牛粪对生菜生长和产量的影响尚未显示出最佳剂量。施用30 t /ha时，株高、叶数、叶面积和鲜重分别增加0.189、0.038、0.931和0.104。给予稻壳灰高达6吨/公顷的剂量对所有观察到的变量没有显著影响。

[CHANGE IN SOIL CHEMICAL CHARACTERISTICS AND YIELD OF MAIZE IN AN INCEPTISOL AS AMENDED WITH COMPOST]. Vast area of inceptisol in Indonesia is a potential natural resource for improving the domestic maize production. The amendment of organic material is expected to make correction on the fertility problem inherent in the soil. Objective of this study was to determine the optimum dose of compost for some soil chemical properties and maize performances. The doses of compost consisted of 0, 2.5, 5, 7.5, 10, and 12.5 ton/haa were allotted randomly on the experimental plots according to completely randomized design with three replications. Observations were made on the exchangeable Aluminum (Al-dd), pH, organic carbon, water content, plant height, unhusked and husked ear weight, and grain yield. Analysis of variance showed that the dose of compost had significant (P?0.05) effects on pH and C-organic in soil. Giving compost at a dose about 12.5 ton/ha could increase the pH about 4.9, whereas giving compost at a dose about 10 tonha-1 could increase C-organic about 3.09 %. In other hand, the giving of compost with various dose did not give significantly (P>0.05) affect towards Aluminium (Al-dd), pH, C-organic, water content, height of plants, weight of without husk, weight of cob with husk, weight of dry corn beans. The highest grain yield (2,415.75 kg/ha) was observed on compost applied at dose 12.5 ton/ha.

[RELATIONSHIP OF SLOPE STEEPNESS TO SOIL WATER CONTENT, SOIL PH, AND PERFORMANCES OF GERGA ORANGE AT LEBONG REGENCY]. In Lebong Regency, gerga orange is commonly grown in hilly areas and many of the crop stands were found on steep sloped land. Objective of this study was to determine the pattern of relationship of slope steepness to soil water content, soil pH, and the overall plant performances. Soil samples were collected from the area below the canopy of 300 gerga orange trees differing in the slope steepness for for soil water content (SWC) and soil pH. The observation of plant performances were also made from the same tree as used for the soil properties observations. The analysis of regression indicated that relationship of slope steepness to both the observed soil properties and plant performances could be represented by the linear models suggesting that all the observed variables were reduced along with the increasing slope steepness.

[GROWTH OF OIL PALM SEEDLINGS IN PRE-NURSERY UNDER DIFFERENT MEDIA COMPOSITIONS AND CONCENTRATIONS OF Azolla pinnata LIQUID FERTILIZER]. Vigourous seedling is prerequisite to successful production of oil palm. Aside from the genetic quality of the planting material, supply of nutrients during early growth of the seedling play an important role in determinting the overall seedling performances. This study was performed to determine the best combination of media composition and concentration of liquid fertilizer made of Azolla pinnata for oil palm seedling growth during pre-nursery. A factorial arrangement of the treatments involving growing media consisted of different composition of oil palm empty fruit bunches compost and soil (1: 1, 1: 2, and 2: 1 v/v) and different concentration of Azolla pinnata liquid fertilizer applications (0, 20, 40, and 60 mL/L) were arranged in a randomized complete block design with three replications. Data were collected for leaf number, stem diameter, seedling height, and leaf greenness at 30, 60, and 90 days after sowing (DAS). A significant interaction effect between the treatments was observed on leaf number at 60 and 90 DAS. A further regression analysis revealed that the highest number of leaves (4.3 at 60 DAS and 6.9 at 90 DAS) were attained on the media composition of 1:1 with liquid fertilizer application at 37.5 and 56 mL/L, respectively. Seedling height and stem diameter at 90 DAP showed quadratic responses to the increasing concentration of the liquid fertilizer applications. The maximum seedling height (26.22 cm) was attained at the liquid fertilizer concentrations of 36.21 mL/L. Similarly, the maximum stem diameter (7.43 mm) was attained at the concentration of 51.00 ml/L. The leaf greeneess at 60 DAS was increased in a linear fashion with the increasing concentration of the liquid fertilizer.

The application of synthetic pesticides can be effective in controlling the pest but it may not be the best solution for the human health and environment. Botanical pesticides have long been known for their potential as the alternative to synthetic pesticides for crop protection with reduced risk to human health and environmental hazard. Objective of this study was to compare the efficacy of papaya leaf extract solutions in controlling cotton aphid and their effect on the vegetative growth of eggplant. Papaya leaf extract solutions differing in concentration (0%, 10%, 20%, 30%, 40%, and 50%) were sprayed onto aphid infested eggplants to observe the insect mortality, crop damage, and the lethal concentration at LC50 and LC90. The mortality of aphid was significantly increased following the application of papaya leaf extract, with the highest mortality (91.33%) was found on the concentration of 50%. The lethal concentrations of the extract causing 50% (LC50) and 90% (LC90) aphid mortality were 9.98% and 41.99%, respectively. As compared to the control treatment, the crop damage was significantly reduced by the application of the papaya leaf extract solution.
