The study on spatial dimension of buffalo development in Brebes is intended to (1) analyze the regional shifting patterns of buffalo development within a period of 5 years (2012-2016) and (2) to identify the relationship between the number of farmland areas and the population of buffalo in Brebes Regency. This research employs a secondary data analysis method by utilizing the available data analyzed using a spatial analysis. Location Quotient (LQ) analysis is conducted to analyze the regional shifting patterns of buffalo followed with a product moment correlation analysis to identify the relationship between the number of farmland areas and the population of buffalo livestock. The results show that the buffalo population is related to the number of ​​rice plant areas (P <0.05) as well as that of the peanut plant areas (P <0.01). For the last 5 years (2012-2016), there is no regional shifting pattern in the center for buffalo development in Brebes Regency. The centralization of buffalo develoment in Brebes Regency is located in Salem, Bumiayu, Sirampog, Tonjong, Larangan and Songgom sub-district

Abstract Background Early maturing provitamin A (PVA) quality protein maize (QPM) inbred lines with tolerance to drought and low-N are needed to develop superior hybrids in West and Central Africa (WCA). This study aimed to (i) identify inbred lines that combined drought and low-N tolerance with increased levels of PVA and tryptophan and (ii) assess the relationship among PVA carotenoids, tryptophan and grain yield. Sixty-four inbred lines plus six inbred checks were evaluated under induced drought, low-N and optimal conditions in 2016 and 2017 in Nigeria. The inbred lines were assayed for PVA and tryptophan contents. Results Thirty-three of the lines were found to be tolerant to drought and low-N. Ninety percent of the inbred lines had tryptophan contents > 0.075 % per sample in whole grain substantiating the presence of the QPM trait in the inbred lines. Inbred lines TZEIORQ 55 and TZEIORQ 29 combined high PVA contents (15.38 and 12.10μg g-1, respectively) with low-N tolerance while nine inbred lines combined moderate PVA levels (5.06 – 8.34μg g-1) with drought and low-N tolerance. Conclusions These maize inbred lines could be utilized to develop superior drought and low-N tolerant hybrids and synthetics with elevated levels of PVA and tryptophan for WCA. The correlations observed among grain yield, PVA and tryptophan of the lines were not significant suggesting that these traits could be improved independently.
