Abstract

The objective of this study was to determine characters of several drought tolerance and high yield upland rice variety under low soil water content in intercrops rice – grass system. The study was carried out in rain water irrigation area of Banjaranyar village. Experimental design was Split Plot Design with three replicates. The  Main plot was grass i.e no grass, elephant grass and lemon grass while  sub plot was upland rice variety i.e. Situ Patenggang, Kalimutu, Danau Gaung, Jatiluhur dan Cisokan. Under very low soil water content (<12%), there was growth and yield differenc between rice varieties grown in intercrops system with grass. Eventhough there was no effect of this intercrop system on plant growth of upland rice, elephant grass promote  higher rice yield, 0.88 t/ha than that without grass (0.39 t/ha) and with lemongrass (0.60 t/ha). Kalimutu variety showed the higher yield (1.38 t/ha)  with plant height  up to 46.27 cm and leaf area up to 4.63 cm2.

Abstract

Drought is one of natural disaster that is commonly difficult to avoid and become a serious problem in crop production in Indonesia. Therefore, this study was conducted to determine the probability of dry spell during several days and its used to determine  safety growing season in Ambon City. Data analyse was conducted in three steps, that is (1) determination of growing season by FAO (1978); ( 2) analysis of dry spell probability; and (3) determination safety growing season. Result of analysis indicated that the growing season in Ambon City took place during 10 months from December to September next year. During the growing season, the probability occuring of long dry spell  (as much as 10, 15, and 20 days) was relatively smaller, less than 45%. The Probability of the dry spell as much as 10 days was equal to 13% on Juli and up to 42% on September; more than as much as 15 days was equal  to 3% on April and May; and up to 19% on September, and as much as 20 days was  equal to 0% on April and May; and up to 13% on September. High dry spell probability was generally occurred by the end of the growing season in September, whereas the lowest probability of dry spell occured in April and May when almost has no long dry spell.

Abstract

Organochlorine insecticide was banned for agriculture but nowadays its residue was still found  in some agricultural soil. One of ways to lowering organochlorine residue in soil is by used of degrading-organochlorine microbial consortia accompanied with compost application. However, application of exogenous microbes might affect bacterial and fungal population in soil. The pot experiment has been set up to verify the influence of Pseudomonas mallei and Trichoderma sp. and compost on total bacteria and fungi on rhizosphere of Cai Sim (Brassica juncea L.) grown on Andisols which were contaminated with organochlorine insecticide of heptachlor, endosulfan, dieldrin and DDT. Experimental design was Factorial Randomized Block Design with three replicates. The first factor was microbial consortia of P.mallei and Trichoderma sp., and the second one was kind of compost. The result showed that effect of microbial consortia on total bacteria population was determined by kind of compost. Total bacterial population in rhizosphere of Cai Sim grown with cow manure compost and microbial consortia was more increased.  However, microbial consortia as well as any kind of compost did not influence total fungal population in Cai Sim rhizosphere. In this experiment, total bacterial and fungal population in rhizosphere reached 109 cfu g-1 and  104 cfu g-1 respectively, indicating that major microbial population in rhizosphere was  in the normal range.

Abstract

Plutella xylostella L. (Lepidoptera: Plutellidae) is one of the major pests on chinese cabbage (Brassica pekinensis). It damage the  2-6 week old plants. Larvae damage  crops by biting, chewing and then eating the lower surface of the leaves. The leaves will become transparent white, severe damage leaves behind only leaf bone. Papaya leaf (Carica papaya) could be used as a pesticide for crops because it contains substances that can inhibit eating even to kill insects pests. The purpose of this study was to verify the efficacy of  the papaya leaf extract against Plutella xylostella. The study was conducted in the laboratory of Plant Pests Faculty of Agriculture, Pattimura University. The design used was a completely randomized design with four papaya leaf extract concentration at 3 instar larvae through the  contact and stomach poison test. Observations were made on the early symptoms of poisoning, the percentage of larval mortality, and further Plutella xylostella stadium. The results showed that the highest mortality in the treatment of stomach and contact poison was occured at a concentration of 40 g/100 ml of water by 100%, while the lowest mortality at a concentration of 10 g / 100 ml of water, respectively by 35% and 20%.

Abstract

Land use is the element that changes very dynamic area. This is due to various human activities depend on the elements of this land. One of the most influential factor in the speed of change in land use or land use change is the increase of population in an area. Fulfillment of human needs (food, clothing and shelter) is influenced by the availability of land. This study aims to identify and analyze the rate of land conversion in conjunction with the growth of population in the peninsula Leitimur Ambon Island. The method used is descriptive with population growth comparing data (statistics) with patterns of changes in land use map data obtained from Ambon city land use remote sensing and data. The rate of population growth in the city of Ambon Leitimur Peninsula in the last 10 years (2000-2010) shows the percentage figures are quite high, 179,78 percent and with a population density of 1.145,436 inhabitants/km2. Land conversion that occurred in the Peninsula Leitimur of the Year 1984 - 2010 are as follows: (1) forest becomes 3.008,06 to  1.057,69 ha; (2) be mixed farms 5.533,46 to 8.671,97 ha; (3) vacant land 0,00 ha to 94.67 ha; (4) settlements be 2.768,58  to 3.129,83 ha; (5) bushes and reeds 4.113,39  to 1.372,58 ha;  and (6) other use 0.00 ha to 1.150,75 ha. From these results show that the rate of change (conversion) of land is directly proportional to the growth of population.

Abstract

Nezara viridula is one of the major pests which attack  bean (Vigna sinensis) plants. Crop damage due to  attack of N. viridula depend on the number of pests, the availability of nutrition as well as  biotic and abiotic factors. The useof synthetic insecticides continuously with inappropriate dose and time application cause negative impact on the environment, therefore the use of insecticide plant is one alternative to reduce pesticide dose. The purpose of this study was to determine the concentration of papaya leaf extract and verify application method which promote  mortality of N. viridula ninfa. Experiment was set up in completely randomized block design with four treatments, i.e 40 g/100 mL of water, 50 g/100 mL of water, 60 g/100 mL of water and 70 g/100 mL of water. Observations were made on early symptoms of toxocity, the percentage of mortality, mortality rate and advanced stages of N. viridula. The results showed that application of papaya leaf extract with at 70 g / 100 mL of water through feed or contact caused 100%  mortality of N. Viridula,  with  mortality rate of 4.75 days and 5.50 days. It is sugeested that  vegetable-based insecticide could be used to decrease N. viridula attack on string bean pod.

Abstract

Agricultural activity is largely determined by the local climate. Climate plays a vital role in  planning agricultural production systems because all of  climate elements has a major influence on various physiological processes, the growth and productivity of plants. In determining the suitability of land for food crops, especially rice plant, level slope data and average values of several weather elements such as rainfall, humidity, temperature and dry months that occurred within a year were requires. Having earned an average values of some elements of the weather,the land suitability analysis can be determined by some criteria. Based on the result of land suitability analysis, there is no area with high land suitability (S1), but more than 50% of the area qualifies as a moderate land suitability (S2). This area lies in the western and southern Merauke
