Abstract

(Test of Association Selected Rhizobium Bacteria with Legumes in Salinity Stress) ABSTRACT. The research aim was to investigate association selected rhizobium bacteria with legumes in salinity stress. Plant media was salin soil that have EC = 20.45 mmhos/cm which taken from Morosari beach, Sayung, Demak. Rhizobium isolate applied was tolerant to 12.000 ppm of NaCl that equaled to electrical conductivity of 20 mmhos/cm. The research was carried out in green house of Laboratory of Forage Science Diponegoro University Semarang. The design arranged was completely randomized design with factorial design 2 x 4 in 3 repeatations. First factor was kind of legumes, T1 = lamtoro (Leucaena leucocephala); T2 = turi (Sesbania grandiflora). and second factor was kind of rhizobium isolates, I1 = without isolate; I2 = rhizobium that was isolated from lamtoro, I3 = rhizobium that was isolated from turi; I4 = combination isolate from lamtoro and turi. The crop growth was observed up to 10 weeks of age. The parameters were 1) crops heigh; 2) sum of leaf crops; 3) fresh weight production; 4) dry weight production; 5) amount and fresh weigh of effective root nodules. The study showed the growth and production of turi in saline media of EC 20.45 mmhos/cm was higher than lamtoro. Root nodule of turi was formed, but lamtoro was not. Turi was more tolerant than lamtoro at very saline media.

Abstract

This research was conducted to investigated the effect of rhizobium inoculation and harvesting time on the productivity of edamame and the chemical composition in the straw edamame. This study was planted edamame soy bean seed. This experiment was carried out in green house used regosol soil in polybag, 2x2 factorial experiment with five replication was arranged in completely randomized design, continued by Duncan?s multiple range test (DMRT) for the significant result. The first factor was harvesting time (U) consisting of harvested at 65 days (U1) and harvested at 75 days (U2); the second factor was inoculant (I) consisting of with inoculation (I1) and without inoculant (I0). The result of the study showed, that underground dry weight (DW) mass yield and DM and OM straw productions, crude protein (CP), nitrogen free extract (NFE) of UP1 were higher (P<0.01) and ash of straw were higher(P<0.05) than UP2. DM and OM pod productions of UP1 was also superior (P<0.05) than UP2. UP2 resulted better fiber crude (FC) (P<0.01) than UP1. Inoculation (L1) resulted better DM and OM straw productions and CP of straw (P<0.01), and underground DW mass yield, FC, NFE of straw were affected (P<0.05) by interaction between treatments. Underground DW mass yield, FC, NFE, DM and OM of straw, and pods productions were not affected by interaction. And all the treatments were also not affected ether extract (EE) of straw.The results of experiment shown that legin factor not signification of in vitro digestibility. The harvest time (U1) was higher (P<0.05) than harvested at 75 days. Interaction among two factors not significant on in vitro organic matter digestibility.

Abstract

This study aims to find out follicular development and hormone profiles post partum Simmental-Ongole cross cattle (SimPO) with legume phytoestrogen supplementation. Research was carried out since April to December 2010 at pens of Laboratory of Animal Production, Faculty of Animal Husbandry, Gadjah Mada University. A total of 15 SimPO post calving were used and distributed into three treatment groups, namely: PO treatment or control (only fed with the standard), PI : PO + 5 g phytoestrogen and PII: PO + 10 g phytoestrogen. Supplementation of phytoestrogen was derived from soy straw. The parameters were estrogen and progesterone profiles and follicle growth dynamic of post partum. The results of this study indicated that supplementation with 5 g phytoestrogen was more significant in affecting the increase in estrogen and progesterone concentrations, compared with the supplementation with 10 g phytoestrogen and control. Ovarian activity characterized by the development of follicles the SimPO began on day 4 post partum for all treatments but only PII treatments indicated that the development of follicles reached the de Graaf follicle with estrogen concentration of 17,801 pg/ml. Key words : Development, estrogen, follicle, legume, phytoestrogen, progesteron.
