The study was conducted to determine the effect of bran composition and baglog size on the production of white oyster mushrooms (Pleurotus ostreatus). The study was arranged in a Randomized Block Design (RBD) consisting of 2 factors with 5 replications. The first factor is the composition of bran consisting of four levels, namely: 10%, 15%, 20% and 25%. The second factor is the size of baglog which consists of 4 levels, namely: 17 cm, 18 cm, 19 cm and 20 cm. The results showed that the composition of bran had a very significant effect on the age of the first harvest, average mushroom weight, average fresh weight per baglog and biological efficiency ratio. Baglog size has a significant effect on the age of the first harvest, average mushroom weight, average fresh weight per baglog and biological efficiency ratio. The best effect on the production of oyster mushrooms is produced by the composition of bran 20% (d3) and baglog size of 19 cm (b3). The interaction of bran composition and baglog size significantly affected the age of the first harvest and had a very significant effect on the average weight of mushrooms, but did not significantly affect the fresh weight of mushrooms per baglog and the ratio of biological efficiency. The best interaction with the production of white oyster mushrooms is a combination of 20% bran composition and 19 cm baglog size.

Clove oil has the potential to suppress the development of the mosaic virus in patchouli plants, but its effectiveness in the field has not been studied. This study aimed to evaluate the effect of clove nano biopesticide on controlling patchouli mosaic disease. The research was conducted at the Manoko Experimental Garden, Bandung, West Java from March to November 2018. The patchouli used was Patchoulina-2 variety, which originated from the Seed Breeder Garden in Lembang, Bandung.  This study was arranged in a Randomized Block Design (RBD), consisting of five treatments and ten replications within each treatment, with one hundred plants in each replication. The results obtained showed that nano biopesticides of citronella, clove, and commercial citronella (Asimbo) were able to reduce the incidence and intensity of mosaic diseases in patchouli plants, showing the efficacy levels of 14.68%, 9.06%, and 5.83%, respectively. The application of citronella and clove biopesticides on Patchoulina-2 every month could increase plant fresh weight, when compared to the plants without treatment. Patchoulina-2 plants treated with nano biopesticides of clove and commercial citronella (Asimbo) showed higher value of fresh weight compared to those treated with citronella nano biopesticide. The clove nano biopesticide can also be developed to control mosaic diseases in patchouli plants.

ABSTRACT: Grasshoppers of the families Acrididae and Romaleidae (Orthoptera) are among the insects that defoliate heliconias and have been gaining status as pests of commercial crops of these plants in Brazil. The objectives of the present study were to identify the grasshopper defoliating heliconias in the municipality of Santo Antônio de Pádua, RJ (Brazil), to evaluate the effect of different levels of shade on the population of this grasshopper and the production parameters of heliconias, and to determine if this grasshopper has an oviposition preference among the heliconias evaluated. The experiment was in a completely randomized block design, in subdivided plots (four levels of shade in the plot, 0%, 30%, 50% and 80%, and four species of Heliconia: H. psittacorum, H. stricta, H. wagneriana and H. psittacorum x H. spathocircinata ‘Golden Torch’ in the subplot), with four replications. The grasshopper was identified as Cornops frenatum frenatum (Acrididae). An increase in shade resulted in a decrease in the number of oviposition holes from the grasshopper and the number of lateral buds. Shade did not influence the number of C. f. frenatum nymphs and adults and the number of flower stems. H. wagneriana was the most preferred species for oviposition by C. f. frenatum. Results suggested using screens to shade heliconia plants can help control C. f. frenatum populations, however, the light requirements of the heliconias should be considered to guarantee productivity.

A field experiment was conducted for two years (2007 and 2008) at the G. B. Pant University of Agriculture and Technology, Pantnagar, to study the productivity, biological efficiency and economics of intercropping in spring maize (Zea mays L.) with sunflower (Helianthus annuus L.) and urdbean (Vigna mungo L.) under different spatial arrangements. The experiment consisting of ten treatments i.e. three sole crops (maize, sunflower and urdbean), six replacement intercropping system of maize with each sunflower and urdbean in row ratios of 1:1, 2:1 and 3:1 and one additive intercropping system of maize with urdbean in row ratios of 1+1 was laid out in randomized block design with three replications. The intercropping system of maize with urdbean in row ratio (1+1) was found beneficial over sole cropping of maize and gave the maximum maize-equivalent yield (5847 kg ha-1), land-equivalent ratio (1.36) and net return (Rs.13420 ha-1). Intercropping of maize in replacement arrangement was not productive and advantageous than respective sole crops. DOI: http://dx.doi.org/10.3329/sja.v12i1.21110 SAARC J. Agri., 12(1): 26-32 (2014)
