Expanding sugarcane (SC) cultivation at the expense of paddy rice (PRC) areas led to soil nutrient cycling changes. The study hypothesized that SC straw return and fertilizer application after land use change (LUC) from PRC cropping would increase soil-crop systems balance, ultimately enhancing growth, yield, efficiency SC. In a field involving 17-year chronosequence 6 (SC6), 13 (SC13), 17 (SC17) years LUC, balance dynamics were monitored in comparison with those PRC. A phosphorus (P)...

Summary Groundnut as a pre‐rice crop is usually harvested 1–2 months before rice transplanting, during which much of legume residue N released could be lost. Our objectives were to investigate the effect mixing groundnut residues (GN, 5 Mg ha −1 ) with straw (RS) in different proportions on: (i) regulating dynamics, (ii) potential microbial interactions decomposition, and (iii) associated nitrous oxide methane emissions at weekly intervals lag phase until transplanting (i, ii) or harvest...

Abstract It was hypothesized that the application of eucalyptus biochar enhances nutrient use efficiencies simultaneously supplied fertilizer, as well provides additional nutrients ( i.e ., Ca, P, and K), to support crop performance residual effects on subsequent crops in a degraded sandy soil. To test this hypothesis, we conducted an on‐farm field experiment Khon Kaen province Northeastern Thailand assess different rates combination with mineral fertilizers upland rice succeeding sugarcane...

In this study, the performance of a proposed treatment system consisting an anaerobic process (acidification, methane fermentation) and aerobic (trickling filter) was evaluated for treating high concentrations molasses-based wastewater (43-120 gCOD/L) by continuous flow experiment. An up-flow staged sludge bed (USSB) reactor, equipped with multiple gas solid separators, used as main treatment/methane recovery process. The USSB showed good efficiency both COD removal (80-87%) (70-80%) at...

Indigenous upland rice is a staple food for local people in the North and Northeast regions of Thailand. As result, variations grain yield GxE interactions have been utilized wider adaptability varieties. A high yielding genotype that performs well under good environment as poor environments greatly needed. Our experiment, therefore, aimed to identify potential indigenous varieties stability rainfed conditions. Fifty genotypes were evaluated from 2013 2015, which randomized complete block...

The information on genotypic responses to the seasonal variation in starch content, yield, and quality of cassava is limited. objective this research was investigate characteristics three genotypes grown under irrigation. experiment conducted at four planting dates (20 April, 30 June, 5 October, 15 December 2015). Three (CMR38-125-77, Kasetsart 50, Rayong 11) were evaluated a randomized complete block design with replications plants harvested 12 months. date contributed largest portion total...

The objective of this study was to investigate the responses peanut genotypes midseason drought, regarding in particular nutrient uptakes and their correlations with biomass production pod yield. experiment conducted during dry seasons 2011/12 2012/13. Five different levels drought tolerance 2 water regimes (well-watered drought) were laid out a split-plot design 4 replications. Midseason imitated by stopping irrigation at 30 days after planting (DAP) then rewatering 60 DAP. data recorded...

Although cassava can be planted throughout the year, its starch qualities may vary based on date of planting. Seasonal variation content, yield, granule size and amylose content cv. Rayong 9 grown under irrigated rainfed conditions were studied for four planting dates in Thailand. A randomized complete block design with replications was used each Planting consisted hot-dry (20-Apr), early-rainy (30-Jun), late-rainy (5-Oct) cool seasons (15-Dec). At final harvest, accounted largest variations...

Information on macronutrient uptake and nutrient use efficiency (NUE) of cassava genotypes under different planting dates is limited. The aims this study were 1) to investigate the responses for NUE 2) identify superior based these traits. Three (Kasetsart 50 (KU50), Rayong 11 (RY11) CMR38-125-77) planted in a randomized complete block design with four replications at (20-Apr, 30-Jun, 5-Oct 15-Dec 2016) harvested 12 months after (MAP). Planting 20-Apr produced highest total crop storage...

Drought is a recurring problem of Jerusalem artichoke (Helianthus tuberosus L.) production under rainfed conditions. A better understanding the responses genotypes to drought can lead improvement inulin content and yield in its planning. The objective this study was compare five (JA60, JA125, JA5, JA89, HEL65) three water regimes (100% available (AW; field capacity), 50% AW, 25% AW) for yield. experimental results showed that were significantly different interactions between also significant...

Matching fertilization with crop needs is important for maximizing yields and reducing fertilizer losses. Seasonal variation in nutrient uptake dynamics poorly understood thus, the ability to optimize strategies limited. This study aims investigate effects of planting dates on macronutrient cassava genotypes full irrigation. The performance genotypes, i.e., CMR38-125-77, Kasetsart 50 Rayong 11, were evaluated early rainy (ERS) post seasons (PRS) two years using a randomized complete block...

Iron (Fe) deficiency in humans caused by inadequate dietary intake is a global nutritional problem. The field experiments this paper were conducted the same paddy over two consecutive years during dry seasons of 2017 and 2018. aims to evaluate effects iron application methods (soil or foliar alone combination soil + foliar) on Fe content brown rice grain compare yields three cultivars, namely Chinat1 (poor concentration), Riceberry Tubtim Chumpae (rich concentration). results show that all...

Phosphorus (P) deficiency is a major factor limiting rice yield throughout the world. Fortunately, some accessions are tolerant and can thrive well, even in soils with low P content. The ability to uptake heritable, thus be incorporated into cultivars through standard breeding methods. objective of this study was screen for tolerance phosphorus validate 1 (Pup1) gene-linked markers Thai indigenous upland germplasm. One hundred sixty-eight varieties were screened solution culture assigned...
