Abstract

This research was studied biological aspects and survival rate of M. vittaticollis Stal. on brown planthopper. The experiment was conducted at the Laboratory of Entomology, Departement of Plant Pest and Disease, Agriculture Faculty, Brawijaya University in May to November 2005. The results showed that the percentage of the eggs M. vittaticollis that hatched was 70,5 %. Adult of M. vittaticollis color was dark brown to black. The forewings covers the abdomen. The long winged adults have hindwings almost twice as long as the abdomen. All legs were yellow to orange with tree segment of tarsus. The age of copulated adult was longer than the uncopulated adults. The age of female was longer than the male. The average of development period was 27,43 ± 3,32 days and the average of body length was 5,13 ± 0,34 mm. Adults female of M. vittaticollis consumed 7,89 ± 0,51 third instar nymphs of brown planthopper and the male consumed 6,02 ± 0,48 third instar nymphs of brown planthopper per day. The oviposition period was 17,1 ± 1,65 days and post oviposition period was iv 1,7 ± 0,66 days. The average fecundity was 42,72 ± 4,09 eggs. Female laid in average of 2,41 ± 05 eggs per day. The survival rate decreased during increasing the level of stage of M. vittaticollis. The survival rate of egg to the adult stage were 70,5 %, 55,5 %, 44 %, 35 % and 31,5 %. The survival rate of first nymph could not be attain 100 % due to the all egg did not hatch and continually decrease till fourth instar of nymph. The mortality of each instar of nymph usually occured during moulting or in few days after moulting.

Abstract

The research showed that the observations made on jatropha from 60 to 180 HST in general had a significant effect on all observed parameters but differed at the age of observation. Parameters of plant length were significantly different from 150 dap of observation, plant height, shoot stem length, number of leaves and canopy width from 120 dap, shoot length from 90 dap, leaf area and leaf area index from 60 dap and the number of shoots was only different significant at the age of observation 60 dap while at 90 to 150 dap was not significantly different. The results of this study also show that planting eggplant on Jatropha land in two cropping patterns will significantly affect Jatropha growth. while for tomato and chili intercrops planted on jatropha plantations using two planting models, it shows that jatropha growth is still relatively good. Based on the estimated calculation of the economic value of the intercrops, it can be seen that the highest economic value is obtained from the planting of the intercrops of the eggplant, both the treatment of the planting pattern with the same spacing in all directions and square spacing with R/C Ratio values of 2.74 and 2.2, then intercrops of chili with R/C Ratio values were 2.12 and 2.11 and the lowest values were shown by the results of tomato intercrops with R/CRatio values of 2.04 and 1.99.

Abstract

This research was to study the effect of N fertilizer doses on the growth, yield and quality of Besuki Na Oogst tobacco plants. The hypothesis put forward is. (1). Application of N fertilizer at certain doses can increase the growth and yield of Besuki Na Oogst tobacco plants. (2). Application of N fertilizer at certain doses can improve the quality of Besuki Na Oogst tobacco plants. The results of the study generally revealed that there were significant differences in the treatment of nitrogen fertilizer doses in the parameters of length, width and area of krosok leaves, production leaf weight parameters and Dekblad and Omblad leaf weights per harvest. On leaf weight production and leaf quality of Dekblad and Omblad, treatment with a fertilizer dose of 50 kg N/ha gave the lowest yield and was significantly different from the other treatments. and treatment of fertilizer doses of 100 kg N/ha to 250 kg N/ha gave results that were not significantly different. Observations made during the study included growth which consisted of leaf length, leaf width, leaf area and number of leaves, harvest observations consisted of leaf gross weight, and post-harvest observations consisted of plant nitrogen analysis, nicotine analysis and quality analysis. The data obtained was tested by analysis of variance (F test) and continued with Duncan's test (p;0.05).

Abstract

The results showed that soaking time in cow urine and number of books did not show any interaction with all variables. Separately, the soaking time did not have a significant effect on all variables at all ages, but the treatment of the number of nodes had a significant effect on root growth and the percentage of live cuttings, number of roots, fresh weight of roots and dry weight of roots at the age of 77 – 100 dap, where the treatment 2 books got the best results. There is a strong correlation between the number of roots and other root growth variables and the percentage of living cuttings. The number of roots influences the growth and percentage of living cuttings, where the roots provide food for the plant. Continuous utilization without replanting results in reduced production and germplasm. Not many bamboo seedlings have been provided due to the length of time needed for nurseries. To overcome this, an effort is needed to accelerate the growth rate and increase the percentage of successful seedlings, namely by soaking the material in auxin ZPT contained in cow urine and the number of books. Cow urine is an alternative provider of auxin ZPT for the high cost of artificial ZPT.

Abstract

Jatropha curcas is a plant from the Euphorbiaceae family which has the potential for medicinal plants and as a renewable energy source. The production and process of seed and fruit formation is highly dependent on environmental genetic factors, agronomy and the interaction between these factors. The quality of the initial growth of the plant is one of the factors that determine the level of production of Jatropha. The aim of this study was to determine the effect of different levels of N and K fertilizer on the initial growth of Jatropha curcas and to obtain the optimal dose. The hypothesis put forward is that there is an interaction of N and K between the application of nitrogen fertilizers and potassium fertilizers on the initial growth of jatropha and rapid growth of jatropha is obtained by providing the highest levels of N and K. The results showed that N application of 40 kg N/ha and without K had the best effect on the initial growth of jatropha compared to other treatments. Meanwhile, the addition of N and K levels had an effect on decreasing the growth of jatropha even though the total N and K content of leaves was high, because high levels of N and K fertilization caused poisoning and salt stress in plants due to the very high status of K content in the soil.
