One of the diseases that often found in sorghum plants is anthracnose disease caused by Colletotrichum sp. The purposed of this study was to determine the effect of adding micro fertilizer and the use of several sorghum genotypes on the intensity of anthracnose disease. The study was conducted in Sukanegara, Tanjung Bintang, South Lampung in April 2017 - February 2018 and at the Laboratory of Plant Diseases and Pests, Faculty of Agriculture, University of Lampung. The treatments were arranged using a randomized block design in a split plot design (3 times replications), the main plot was micro nutrients (with micro addition and without micro addition) and 15 subgroups of sorghum genotypes (Numbu, Samurai 1, GH3, UPCA, GH4, P / I WHP, GH6, Super 2, GH13, P / F 51-93-C, Super 1, GH5, Mandau, GH7, and Talaga Bodas). The results showed that the addition of "ZincMicro" micro fertilizers to sorghum plants did not affect the intensity of anthracnose disease, however there were differences in the intensity of anthracnose diseases between sorghum genotypes. Numbu Genotype, GH 3, and GH 13 were relatively more resistant to anthracnose disease than the other genotypes.

Genetic diversity is an essential prerequisite for improving the genetic makeup of any crop. Inclusion of genetically diverse parents in hybridization programme helps in isolation of superior recombinants. So, an experiment was conducted to investigate the genetic diversity among 150 genotypes of sorghum [Sorghum bicolor (L.) Moench] Rajasthan during Kharif - 2013, 2014 and 2015 in a Randomized Block Design (RBD) with three replications. Present study reveals that the clustering pattern based on D2 statistics grouped 150 genotypes into 6 clusters, out of which cluster 1 shows the highest intra cluster value (142.62) followed by cluster 2 (119.47). While maximum inter cluster distance (i.e.652.68) was observed between cluster 5 and cluster 6, indicating there is presence of wide range of genetic diversity among the sorghum genotypes. Such genotypes with wide genetic diversity based on their mean values can either be utilized for breeding programmes for genetic improvement in sorghum or directly adopted as a variety.

Phytoremediation using Sorghum (Sorghum bicolor L.) plant is an alternative green technology to overcome oil polluted soil. Improving of the phytoremediation performance are needed stimulating agent to enhance the rate of hydrocarbon biodegradation and increase the plant growth. One of the bioagent that can act as biostimulant is Azotobacter sp. and Pseudomonas sp., because thouse bioagent can provide elements N and P, and phytohormone for sorghum plants. The purpose of this study is to examine the role of Azotobacter sp. and Pseudomonas sp. as a biostimulant for Sorghum bicolor L. in the process of biodegradation of petroleum hydrocarbon in soil system. The factorial randomized block design was used as the experimental design. The treatment consisted of 4 application levels of Azotobacter sp. and 4 levels of application of Pseudomonas sp. The results showed that there was no interaction between Azotobacter sp. and Pseudomonas sp. aplication on the efficiency of hydrocarbon degradation of the population of Azotobacrer spp., Pseudomonas spp. and plant height increase. Azotobacter sp. and Pseudomonas sp. also did not show an increase in value on each test variable. While, the potential of sorghum plants without the application of Azotobacter sp. and Pseudomonas sp. (control treatment) showed the value of the efficiency of biodegradation in the range of values of 60.442% - 68.165% during 14 weeks period and not significantly different from other treatments.

This study was conducted in Balai Benih Induk (BBI) Luwus, Baturiti District, Tabanan Regency, with the high of place 506m above sea level occurring in March to May 2014. This research used randomized block design arranged per factor, namely population of plants (P) including three steps: P1=80.000 plants per hectare, P2= 100.00 plants per hectare, P3= 120.000 per hectare; and mulch (M) that include: M0= without mulch and without cleaning, M1= without mulch with clean weeding, M2= rice plants straw mulch (5 ton per hectare) and M3= black silver plastic mulch. Eventually, there were 12 combination treatments, each of which was repeated 3 times to obtain 36 land slots. The research indicates that there was no real interaction between the treatment of plant population and mulch usage in all variables observed. The 100.000 plant population per hectare can produce the weight of dry and fresh oven corn kernel without highest cornhusk that was to say 4.79 tons and 0.53 tons or 11.66 % and 20.45% higher compared to 120.000 plant population per hectare. The use of black silver plastic and rice plants straw mulch can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare each of which is 4.69 tons, 4.57 tons, and 0.54 tons, 0.47 tons or 26.76%, 38.46 %, and 23.51 %, 20.51 % higher than without mulch and without clean weeding. Clean weeding treatment can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare with its weight of 4.63 tons and 0.51 tons or 25.35 % and 35.90 % higher than without mulch and cleaning. Clean weeding treatment was not obviously different from mulch treatment. The identification of weed types were 19 kinds of weeds and Cyperus rotundus L. Weeds. They have the highest density and each absolute frequent of 1249.333 stems m-2 and 1.00.

ABSTRACT The goal of the present study is to assess the physiological potential of Byrsonima crassifoliaseeds and analyze the procedures of the germination and tetrazolium tests, as well as the conservation of such seeds by testing different combinations of packaging and environment. The experiment used pyrenes of the clone Açu, collected from mother plants in the germplasm collection of muruci plants of Embrapa Amazonia Oriental, in Belém, Brazil. Different temperatures were tested in the germination test (25, 30, 35 and 20 - 30 ºC). The best methodology and assessment dates were determined for the test, and the seedlings of the species were characterized. Viability was assessed with the tetrazolium test, with combinations of hydration methods (by immersion and between paper towels), staining periods (3 and 4 h) and concentrations of tetrazolium solution (0.5, 0.7 and 1.0%). Storage of muruci pyrenes was evaluated at three, six and twelve months, in polyethylene and Kraft paper bags, under dry chamber and refrigerator conditions. The study used a randomized block design with four replicates. The data underwent analysis of variance. In conclusion, the physiological potential of seeds of B. crassifoliacan be assessed by the germination test conducted in sand, with alternating temperatures of 20-30 ºC, or with the use of the tetrazolium test (with staining for three hours in the tetrazolium solution at 1.0%) as a rapid assessment of viability. Muruci pyrenes can be kept in polythene or paper Kraft bags for up to 12 months, in a dry chamber at 16 ºC and with relative air humidity of 50 to 60%.
