Abstract

Onions are commodities that have high economic value. Demand for shallots continues to increase along with population growth. The use of appropriate planting media will determine growth and yield. In general, a good growing media is a medium of fertile soil, rich in organic matter, availability of nutrients in sufficient quantities, and the ratio of air and water contained in it is balanced. The purpose of this study was to determine the effect of doses of baglog compost (oyster mushroom waste) on the growth and production of shallots. The research was carried out in polybags in the Bandar Lampung experimental plot. The 4-month research period starts from November 2016 to February 2017. The research method used a Randomized Block Design (RBDD) with five replications. The composition of baglog compost with volume consists of six levels: K0 = control treatment; K1 = ground: baglog (3: 1); K2 = land: baglog (2: 1); K3 = ground: baglog (1: 1); K4 = land: baglog (1: 2); and K5 = ground: baglog (1: 3). Research results: (a). Application of compost doses on soil treatment of 50%: baglog 50% has a significant effect on higher growth and production, namely on variable plant height = 53.57 cm; number of tubers = 5.40 pieces; tuber weight = 31.53 grams; and tuber diameter = 2.05 cm. While the application of baglog compost with a composition of 67% of land: 33% of baglog gives a real effect on the variable number of leaves is greater as many as 13 strands, and the wet weight of onion is 48.10 grams. Composition of baglog soil compost 33%: baglog 67% and soil 25%: baglog 75% shows low parameter results. In the treatment of 33% of land: 67% compost bagasse and 25% soil: baglog compost 75%) the intensity of fusarium wilt attacks reached 14.67%, and 35%. The greater the amount of baglog given to the planting media allows the growing media to store more water and the higher soil moisture.

Abstract

Rubber (Hevea brasiliensis) is an important plantation crop in Indonesia because its products are used as raw material for rubber industry and source of stock-exchange. The existence of weeds on the rubber land causes competition of growing facilities and affect the growth of rubber plants. One of the most common herbicide active ingredients that used to control immature plant weeds is isopropylamine glyphosate. This research aims to (1) find out the dose of isopropylamine glyphosate herbicide that effectively control weeds in immature rubber cultivation, (2) to know the change of weed’s composition due to the application of isopropylamine glyphosate herbicide, (3) to know whether the phytotoxicity of rubber plants occurs due to isopropylamine glyphosate herbicide application. This research was conducted in smallholder rubber plantation in Marga Agung Village, Jati Agung Subdistrict, South Lampung Regency and Weed Laboratory of Agriculture Faculty of Lampung University from November 2016 until March 2017. This research used randomized block design (RAK) with four replicates and six treatment levels dose of herbicide isopropylamine glyphosate herbicide 796,5 g/ha (P1), 1062 g/ha (P2), 1327.5 g/ha (P3), 1593 g/ha (P4), mechanical weeding (P5), and without restraint/control (P6). The homogeneity of various data was tested by Bartlett test, the data additivity was tested by Tukey test, and the difference of median treatment was tested by Least Significant Different (LSD) test at 5% level. The results showed that: (1) isopropylamine glyphosate herbicide dose 796,5 – 1593 g/ha effectively controlling total weeds, grass weeds up to 12 weeks after application and nut grass weeds up to 4 weeks after application, and dose 1593 g/ha effectively controlling leaf weeds up to 8 weeks after application, (2) dose 1327,5 – 1593 g/ha effectively controlling Ottochloa nodosa weeds up to 12 weeks after application and Commelina diffuse up to 4 weeks after application, (3) dose 796,5 – 1593 g/ha effectively controlling Cyperus brevifolius weeds up to 4 weeks after application, and doses of 1593 g/ha effectively controlling Asystasia gangetica weeds up to 8 weeks after application, (4) doses of 796,5 – 1593 g/ha resulted in changes in weed’s composition at 4, 8, and 12 weeks after application, (5) doses 796,5 – 1593 g/ha does not poison the rubber plant.

Abstract

The study aimed to was determine the effect of dose and time of fertilization bio-slurry liquid fertilizer on the growth and yield of sweet corn was held in Tanjung Laut, Fajar Baru village, Jati Agung district, South Lampung regency in October 2016 to January 2017. In this study used Randomized Block Design (RBD) with factorial treatment design (4 x 2) with three replications. The first factor was the dose of bio-slurry liquid fertilizer consisted 4 levels were 0, 25, 50, and 75 l/ha. The second factor was the fertilization time consisted of 2 levels were (2 and 4 MST) and (2, 4, and 6 MST). Variance of homogeneity was tested by Bartlett's test, if the assumptions were met, the data were analyzed by variance using F-test. The difference of median value of treatment will be tested by the Least Significance Difference Test (LSD) at 5% level. The results showed that the treatment of several doses of bio-slurry liquid fertilizer has an effect on the length of cob, while the treatment of some fertilization time has an effect on dry weight variables. However, the treatment of some dose levels and fertilization time of bio-slurry liquid fertilizer has not been able to increase growth and yield. Proper fertilization time does not depend on the dose of bio-slurry liquid fertilizer given in influencing the growth and yield of sweet corn crops.

Abstract

The challenge for plant breeders can not be separated from the interaction effects between genotypes and the environment, where the tested strains show different results at each test site. Therefore, to know a strain or genotype that has a level of stability it is necessary to do the testing phase. The currently developed strains are RG1, RG2, RG3, and RG4. Currently the strains have entered the third generation. Furthermore, the four rice strains will be planted in the fourth generation and continued by the fifth generation. This research was conducted at Field Polytechnic of Lampung State of Lampung, Bandar Lampung on September 2015 - January 2016 planting F4 and January - May 2016 planting F5. The objective of this research is to obtain new strain of rice that is able to maintain the stability of the results by looking at the phenotypic appearance character and the potential yield that is planted on F4 and F5. The design used in this study is the design of split plot with main plot treatment using two generations (F) that is F4 and F5. While in sub plots using 4 new rice strains (G) are RG1, RG2, RG3, and RG4. Data were analyzed by LSD Test at 5% level. Stability analysis using Francis and Kenneberg (1978) models, by looking at the mean squares (Si2) and the Coefficient of Varians (CVi). From the result of observation of stability result of four rice strains in two different planting generations it can be concluded that the strains that exhibit phenotypic character and stable yield potential on F4 and F5 are RG1 and RG2. The strings showing potential unstable results on F4 and F5 are RG3 and RG4.
