One of the efforts to increase the yield of rice plants is to trim the foliages before flowering, in addition to the application of ‘Unitas Super’ liquid organic fertilizer (LOF). The study was carried out in the Lubuk Lintah Village, Padang City in May - September 2017. The aim of the study was to investigate the effectiveness of pruning, as a source of forage, and the concentration of ‘Unitas Super’ liquid organic fertilizer in improving rice yields. The experiment was arranged in split plot design with main plots consisting of 2 levels, namely pruning at 45 days and without pruning. The subplots consisted of 3 concentrations of ‘Unitas Super’ liquid organic fertilizer, namely 0 ml L -1 , 50 ml L -1 , and100 ml L -1 . All treatments were replicated 3 times. Data were analyzed statistically using the F test at 5% and tested using LSD at 5%. According to the results of the observations, it can be concluded that pruning reduced the weight of 1000 seeds and panicle length, but did not reduce the yield of harvested dry grain and harvest index. Application of ‘Unitas Super’ liquid organic fertilizer did not significantly increase the growth and yield of Black Madras purple rice. The highest dry grain yield was 4.04 t ha -1 observed in plants sprayed with 50 ml L -1 ‘Unitas Super’ liquid organic fertilizer without pruning treatment.","PeriodicalId":31703,"journal":{"name":"Planta Tropika Jurnal Agrosains","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73203966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research, aiming to identify the effects of direction, panel height, and tapping frequency on daily bark consumption, was carried out at Sungei Putih Research Center, North Sumatera and several estates in Lampung (Kedaton, Bergen, and Way Lima) from January to March 2018. The observations involved 15 tapping tasks consisting of GT 1, PB 260, and mixed clones. Bark samples were collected from 10 randomized trees in each task. Tapping direction was distinguished as downward tapping and upward tapping, while panel height was classified into 170 cm in upward tapping. Tapping frequency effect was investigated in a trial plot using frequency of once in three days (d3), once in four days (d4), once in five days (d5), once in six days (d6), and once in eight days (d8) on the basal panel (B0-2). Bark consumption was measured directly using a digital caliper. The observation result indicated that upward tapping had higher bark consumption than downward tapping. In downward tapping, the lower tapping position, the higher bark consumption would be, whilst in upward tapping, bark consumption increased along with the panel height. Low tapping frequency (d4, d5, d6, and d8) showed higher bark consumption per tapping than d3, yet they had lower cumulative bark consumption per year.","PeriodicalId":31703,"journal":{"name":"Planta Tropika Jurnal Agrosains","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81884465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research objective was to identify the resistance of soybean genotypes to the pod feeders. The existence of the pod feeding insects was evaluated on 24 soybean genotypes planted in Ngawi (Indonesia) in 2016. The experiment was arranged in a randomized block design with two environmental conditions. The first environmental condition was plants controlled by insecticide during plant growth, and the second condition was plants controlled by insecticide only up to 45 days after planting (dap). The pod feeding insects included pod sucking bug (Riptortus linearis), pod borer (Etiella zinckenella), and podworm (Helicoverpa sp.). The damage intensity of pod sucking bug at 45 dap of controlled environment reached 60.24%, meanwhile the damage intensity of pod borer and podworm were 46.08% and 3.85%, respectively. This indicates that the natural population of pod sucking bug is relatively high and dominant. Of 24 soybean genotypes tested, NSP-16-2-8 was consistently resistant on environments with and without insecticide application, whereas NSP-16-1-4 was consistently resistant to the pod borer attack. Those genotypes were potential to be used as source of genes for pod feeding insects’ resistance in the breeding program.","PeriodicalId":31703,"journal":{"name":"Planta Tropika Jurnal Agrosains","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77837573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vegetation i s a source of organic material that produces root exudate containing organic acids. These acids accelerate the dissolution process of volcanic material so that it affects the soil characteristics. This study was conducted to analyze the effect of four types of perennial plants on soil chemical and physical characteristics. The soil samples were taken on the area planted with cinnamon, albizia, bamboo, and acacia, at depths of 0 – 10 cm, 10 – 20 cm, 20 – 30 cm, 30 – 40 cm, and 40 – 50cm.

The results show that pH H 2 O, pH KCl, C-organic, humic acid and fulvic acid, CEC, K, Na, Ca, Mg, available P, base saturation, and particle size distribution were significantly affected by vegetation type. Meanwhile, the pH of NaF was not significantly influenced by vegetation type. Cinnamon is a plant that gives the strongest influence in the improvement of soil chemical-physical properties compared to the other three types of vegetation. Therefore cinnamon is quite prospective plant to be developed for post-eruption land reclamation.","PeriodicalId":31703,"journal":{"name":"Planta Tropika Jurnal Agrosains","volume":"44 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90971814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
