This research was conducted in Pante Cermin, Padang Tiji Subdistrict, Pidie District. in March to August 2015, with the aim to know the use efficienci of Trichoderma sp on the growth of several types of Banana seedlings (Musa Paracica L.) This research using Randomized Block Design (RAK) factorial pattern with the factors studied is the type of banana and trichoderma dose . Both factors consist of 4 levels: Banana Barangan (J1), Ambon banana (J2), Banana King (J3) and Geupok banana (J4). While the dose of Tricoderma sp is: TO = 0 g / seeds T1 = 15 g / seeds T2 = 30 g / seedlings and T3 = 45 g / seedlings. So there are 16 treatment combinations and repeated 3 times, which resulted in 48 experimental units.To determine the influence of each treatment and its interaction on the growth of banana seedlings, the analysis of variance (Test F) and continued with the test of Beda Nyata Jujur (BNJ) at 5% level.The results showed that the growth of good banana seedlings among 4 species studied was shown by Barangan bananas, but not unlike bananas. However, trichoderma administration until the age of 4 months has not shown the growth and intensity of different attacks. So it should be extended the study period to 6 months. After 6 months of research there has been a difference in growth and intensity of attack, where the intensity of the greatest attack is shown by T0 (without trichoderma). Medium intensity of smallest attack is shown by T3 (Dose trichoderma sp 45 gr / banana seedlings). The type of banana does not affect the growth and intensity of fusarium wilt attack. and the interaction of these two factors had no significant effect on the growth of banana seedlings and the intensity of Fusarium wilt disease.

Twenty genotypes of chickpea were evaluated to study the interaction of chickpea genotypes, mesorhizobial strains and vesicular arbuscular mycorrhiza for 14 nitrogen fixing and yield attributing traits viz. days to 50% flowering, days to maturity, plant height (cm), number of branches per plant, number of pods per plant, 100 seed weight (g), seed yield per plant (g), number of nodules per plant, nodule weight per plant (g), root dry weight per plant (g), shoot dry weight per plant (g), nitrogen content in shoot (%), nitrogen content in grain (%) and VAM infection(%). The analysis of variance revealed the existence of significant amount of genetic variability in the material for all the traits. All the genotypes were treated with three treatments separately (Mesorhizobium sp. Strain CH 1233 (S1); Mesorhizobium sp. Strain CH 810 (S2); vesicular arbuscular mycorrhiza (VAM) (Glomus fasiculatum) and one set was used as uninoculated control. These were grown separately following randomized block design with three replications in each treatment. Comparative analysis indicated the differences between the treatments and behaviour of the genotypes in different environments. In general S1 and VAM showed beneficial interaction for maximum number of traits for all the genotypes. The effect of VAM was the most apparent among treatments. On overall basis, genotypes viz. HC 3, HC 5, GL 94022, ICC 5003LN, HK 2, GNG 663 and BG 362 were observed to be better performing and responsive to bio inoculants having one or more superior traits. These genotypes performing better for specific traits can be used as parents in hybridization programme for improvement of that particular trait.

ABSTRACT<br />    <br />As one of the silica (Si) accumulator, rice (Oryza sativa L.) requires large amounts of silica for growth. This study aimed to determine the effect of liquid silica fertilizer application on lowland rice growth and yield, and its roles in drought stress responses. The experiments were conducted at Sawah Baru rice field and Cikabayan Greenhouse Experiment Station, IPB, Bogor during the period of January to May 2016. The field experiment was set up in a randomized complete block design with 7 treatments and three replications. The greenhouses experiment was arranged in a split-plot randomized block design with 3 replications. The main plots were 5 levels of liquid silica fertilizer application, while the subplot was 5 level of various soil water contents. The results of the field experiment showed that the application of liquid silica fertilizer increased rice shoot dry weight, total and productive tiller numbers, and yield per plant, but did not increase yield per hectare. Meanwhile at greenhouse experiment, it showed that the use of liquid silica fertilizer reduced the number of rice stomata, but did not increase cuticle thickness and grain yield per plant. Silica application was not effective to alter drought in rice.<br /><br />Keywords: IPB 3S, silica fertilizer, soil water content, water use efficiency   <br /><br />
