Drought affects plant physiology processes such as photosynthesis, respiration, mineral and water transportation, and transpiraton, briefly called drought stress. Drought stress can be avoided by managing environment. Furrow containing organic matter for rain fed rice has been the subject of many studies, with special emphasis on soil moisture. This research is aimed to know the effects of the furrow containing organic matter on physiological responses of several upland rice varieties on agroforestry system based on kayu putih (cajuput). The experimental design applied the strip plot design. The vertical factor is the furrow system of treatment consisting of 2 levels i.e. without furrow + without organic matter and furrow + organic matters. The horizontal factors are the upland rice varieties consisting of 3 varieties i.e. Situ Patenggang, Situ Bagendit and Ciherang. The collected data were analyzed by Analysis of Variance (ANOVA) applying a level of significance α = 5%. Whenever significant differences among treatments were found, further analysis was carried out by applying the Tukey's HSD (Honestly Significant Difference) test α = 5% levels. The result shows that drought affects plant physiology and can be avoided by using furrow containing organic matters. Situ Patenggang with furrow containing organic matters has the higher physiology capability, it had photosynthesis 387.18 µmol CO2 per clump s-1, transpiration 3038.50 mg per clump per secondand CO2 721.11 mol CO2 clump per mol. There different plant requirements for Cu between varieties.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45360348","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}

Sugarcane is cultivated in Madura, particularly in four regencies, namely Bangkalan, Sampang, Pamekasan and Sumenep. To decide the location of mini sugar mill in one of the regencies requires decision support system (DSS). This study aimed to determine the priority of mini sugar mill location in Madura. This research used primary and secondary data. The primary data were collected using questionnaires. Then, the results of evaluation from the experts, on the items of questions, were analyzed with analytical hierarchy process (AHP). This was accomplished using Expert Choice 2000 software. Analysis of the selection of mini sugar mill location considered six criteria, namely the land suitability level, existing infrastructure, the potential of raw materials, the availability of labor, social capital and institutions. The selected criteria were further classified into sub-criteria to clarify the definitions of operational criteria and facilitate assessment for respondents. The results show that social capital had the greatest influence on decision making, followed by the land suitability level and the potential of raw materials. The finding in this research is that the mini sugar mill location is given priority in Bangkalan Regency, Madura. The conclusion of this research is that AHP analysis can be used as a method to take accurate decision in determining the location of sugarcane factory in certain area of sugarcane farming business development.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42960681","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}

Public consumption of flour-based food, such as noodles and bread, is in great demand. This study aims to determine the calculations, perceptions and attitudes of farmers towards wheat farming, considering that Indonesia is a non-wheat developing country. This qualitative descriptive research using in-depth interviews with 7 informants and observation methods was conducted in Klaten and Demak Regencies. In analyzing the data, this study used an interactive analysis model including data reduction, data presentation and conclusion drawing. The results show that: 1) based on farmers' calculations, wheat farming is financially not profitable to farmers because the products harvested are not worth the expense; 2) farmers' calculations affect farmers' perceptions which shifted to negative perceptions that wheat farming is not as promising as other farming businesses. Despite the negative perceptions, wheat farming has provided a valuable experience for farmers which is shown by their pride and pleasure and 3) the majority of farmers are not interested in wheat farming, which is shown by their attitude of not being able to accept wheat farming, while other farmers behave otherwise, indicated by their willingness to recommence wheat planting testing. Further research may examine: 1) how to change the culture of rice farming into culture of wheat farming; 2) how to change subsistence rice farming into enterprise and 3) how to change rice farming as social activities to rice farming as business activities.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45948882","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 study aimed to investigate climate change-induced agricultural drought over the moist-cool and moist-warm climatic zones, using historical precipitation and temperature data recorded in the crop growing months for 35 years. The changes of temperatures and precipitation were analyzed using Mann Kendall trend test. Agricultural drought indices were analyzed using R-model by withdrawing potential evapotranspiration from precipitation to determine the existing water balance. The values of drought indices were used to characterize the duration, severity, intensity and trends of agricultural drought. Results showed that the changes in maximum and minimum temperatures and precipitation were significantly stronger in the Ale Woreda (P<0.05). However, minimum temperature and precipitation in Adami-Tulu did not noticeably change. The spatial drought events occurred more widely in Ale than in Adami Tulu. The events occurred 12 and 17 times with cumulative severity indices of 41.95 and 48.22 in Ale and Adami-Tulu, respectively. Agricultural drought intensities of the two districts were labeled as “severe” and “moderate dry”, for Ale and Adami-Tulu, respectively. The intensity of drought in Ale district significantly increased (P<0.05) and that in Adami-Tulu negligibly changed. Therefore, the study explicitly showed that more changes in temperature and precipitation aggravated agricultural drought in Ale than in Adami-Tulu more intensely and it is suggested that more attention shall be paid to Ale Woreda.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42341523","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}

Variance analysis showed that there was a very significant difference (p <0.01) among the genotypes tested for all observed characters indicating variability. In this study, the phenotypic coefficient of variance (PCV) values was relatively higher than the genotypic coefficient of variance (GCV) for all traits. However, GCV values were close to PCV values in some characters such as plant height, flowering age, harvest age, rice color and anthocyanin content which showed a high contribution of genotypic effects to the phenotypic expression of these characters. The high heritability and high average value of genetic advance were indicated in the parameters of plant height, flowering age, harvest age, rice color and anthocyanin content. The characters of plant height, flowering age, harvest age, rice color and anthocyanin content can be used as sixth-generation black rice selection criteria.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42561346","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}
