“…The effects of drought stress on plant physiology activity are determined by periods and intensity of stress, stage of plant development (Bastos et al 2011), and also the characteristics of plant (Fathi and Tari 2016). This opinion is also in line with that explained by Peijic et al (2013) that the production of cowpea exposed by drought is affected by genotype, period and intensity of stress, stage of plant development.…”

Abstract. Karuwal Rl, Suharsono, Tjahjoleksono A, Hanif N. 2017. Physiological responses of some local cowpea from Southwest Maluku (Indonesia) varieties to drought stress. Biodiversitas 18: 1294Biodiversitas 18: -1299. The aim of this study was to analyze the physiological responses of some local cowpea from Southwest Maluku (Indonesia) varieties to drought stress. The physiological responses were analyzed by measuring plant height, number of leaves, relative water content (RWC), and chlorophyll content using Anova and were continued with Duncan test at 5% significance level. Results of this research showed that the varieties and drought stress in the form of watering periods to affect to all variables except plant height. Physiological responses showed that at every ten days watering periods, the crimson varieties gives the highest plant height (33.85 cm), the brown varieties gives the highest number of leaves (30), the dark brown varieties have the highest RWC (88.675%), and the highest content of chlorophyll a (0.5088 mg/L), chlorophyll b (1.595 mg/L), and total chlorophyll (1.5095 mg/L) are found in white varieties. The supply of water at every ten days is the optimum time of drought stress in cowpea. Further research will be needed on the responses of the other variables for screening, selection, then multi-location trials to obtain tolerant local cowpea varieties to drought.

“…There was a sudden drop in the length of the plumule from 8.95 cm in control to 1.14 cm in -0.4 MPa and further reduction of the water potential to -0.6MPa and -0.8MPa caused complete inhibition of the growth of the plumules in all the genotypes tested for mungbeans [14]. With rising drought severity the root length in millet was reduced [24]. Root length in PEGtreated grass peas was reduced by 30% compared to control peas and decreased by 41% and 57%, respectively, compared to controls in peas [23].…”

Sixteen advance genotypes of mungbeans under 5 different concentrations of Polyethylene Glycol (PEG) were studied to find out the better cultivar against drought stress condition. The experiment results revealed that germination, seedling production and water-related behavior of mungbean genotypes differed significantly under different PEG (drought inducer) concentrations. The mungbean genotype BINA Mung-6 (V 8 ) is proved as highly tolerant against drought stress condition among all other tested genotypes. The results of the investigation revealed that BINA Mung-6 (V 8 ) genotype consistently scored the highest value for all parameters except for the root shoot ratio and water retention capacity that was statistically comparable to genotypes BARI Mung-4 (V 2 ) and BINA Mung-5 (V 7 ). Consistently poor performance were recorded from IPM-02-03 (V 16 ) genotype which is Imtiaz et al.; ARRB, 35(2): 1-12, 2020; Article no.ARRB.55650 2 statistically similar as genotypes BMXK1-09015-2 (V 13 ) and BMXK1-09015-6 (V 10 ). The maximum percentage of germination (98.12%), shoot length (139.40 mm), root length (99.07 mm), shoot dry weight (22.32 mg), root dry weight (6.88 mg), relative water content (94.78), water retention capacity (24.98), germination co-efficient (22.27) and vigor index (233.90) were reported from BINA Mung-6 (V 8 ) at a concentration of 0 percent PEG. The minimum percentage of germination (28.22 percent), shoot length (31.17 mm), root length (16.50 mm), shoot dry weight (2.21 mg), root dry weight (0.97 mg), relative water content (25.55), water retention capacity (3.08), germination co-efficient (6.06) and vigor index (13.45) were reported from IPM-02-03 (V 16 ) mungbean advance lines at 0 percent PEG. Maximum (0.92) root shoot ratio was recorded from both BARI Mung-8 (V 6 ) and BMX-08011-2 (V 11 ) mungbean genotypes at 20 percent PEG concentration and minimum (0.22) at 0 percent PEG concentration from BARI Mung-5 (V 3 ) genotype. Maximum water retention capacity (74.45) was recorded at 20 per cent PEG concentration from IPM-02-03 (V 16 ) genotype and minimum (5.22) was at 0 per cent PEG concentration from BINA Mung-6 (V 8 ) genotype.

“…The phenomenon of the relationship between economic growth and income disparity was introduced by Simon ( Kuznets, 1955) which illustrates the relationship between per capita income and evenness of income distribution in reverse U-shaped letters (Todaro and Smith, 2015). The relationship between per capita income and of income distribution illustrates at the beginning of the development phase, the distribution of income between households will tend to be uneven, but after reaching a certain level of development, distribution of income will be more evenly distributed (Nemati and Raisi, 2015). (Dartanto and Brojonegoro, 2013) in their research on "The Impact of the Fiscal Decentralization on Economic Growth and Disparity between Regions" construcs a simultaneous econometric macro model dividing into macroeconomic blocks and regional financial blocks.…”

The allocation of OtonomiKhusus (OTSUS) funds for the Province of Aceh becomes a source of revenue that is able to increase the regional fiscal level. This study aims to identify regional disparities in Aceh and the implication of OTSUS fund allocation against inequality. The analysis model uses the Williamson index and Theil Index, which is then performed multiple linear regression analysis of time series analysis. The results show that the regional disparities in Aceh Province during the OTSUS period have decreased. The allocation of Otsus funds has a significant impact on regional disparities. The gap in the OTSUS period has tended to decline, with a decrease of 65 percent. Human Development Index and economic growth are determinants that can reduce regional disparities in Aceh.
