Cucumis Melo L

Two cultivars (Huanghemi and Elizabeth) of muskmelon (Cucumis melo L.) were evaluated to determine the effect of photon flux density (PFD), leaf temperature, and CO,2 concentration on the net photosynthetic rate (Pn). The cultivars were evaluated under open field and solar-heated greenhouse conditions in northwest China. The Pn increased as the PFD increased, and then the rate of increase in Pn declined for Huanghemi and decreased for Elizabeth. Elizabeth registered 22 µmol m-2 s-1 for light compensation and 1127 µmol m-2 s-1 for light saturation, which, respectively, were 50 and 70% of those required by Huanghemi. The Pn increased with increasing leaf temperatures in the range of 9.8 to 50.8°C. The optimum temperature for photosynthesis was 35.3°C for muskmelon grown in open field, 2.4°C (7%) greater than that for muskmelon grown in the greenhouse. At optimal temperatures, the field-grown muskmelon had the Pn of 19.8 µmol m-2 s-1, 30% greater than that for the greenhouse-grown muskmelon. Both cultivars responded positively to CO2 concentrations of below the CO2 saturation points, whereas Huanghemi exhibited greater (51%) Pn and higher (49%) carboxylation efficiency than Elizabeth at optimal CO2 level. The two cultivars exhibited greater photosynthesis in open field than when grown in solar-heated greenhouses, while Elizabeth performed better than Huanghemi when light conditions were poor. Selective use of cultivars with low requirements for light and temperatures will enhance the photosynthesis and productivity of muskmelon grown in solar-heated greenhouses of northwest China. Key words: Light compensation, light saturation, photon flux density, transpiration

AbstractSoil moisture plays an important role in land-atmosphere interactions, agricultural drought monitoring, and water resource management, particularly across arid regions. However, it is challenging to simulate soil moisture of high spatial resolution and to evaluate soil moisture at fine spatial resolution in arid regions in Northwest China due to considerable uncertainties in forcing data and limited in situ measurements. Then, the data set was used to produce the 1 km high-resolution atmospheric forcing datasets and to drive the Community Land Model version 3.5 (CLM3.5) for simulating spatiotemporally continuous surface soil moisture. The capabilities of soil moisture simulation using CLM3.5 forced by the XJLDAS-driven field were validated against data obtained at three soil layers (0–10, 0–20, and 0–50 cm) from 54 soil moisture stations in Xinjiang. Results show that the simulated soil moisture agreed well with the observations [CORR > 0.952], and the intra-annual soil moisture in Xinjiang gradually increased during May through August. The main factors that affect changes in soil moisture across the study region were precipitation and snowmelt. The overall finding of this study is that an XJLDAS, high-resolution forcing data driven CLM3.5 can be used to generate accurate and continuous soil moisture of high resolution (1km) in Xinjiang. This study can help understand the spatiotemporal features of the soil moisture, and provide important input for hydrological studies and agricultural water resources management over the arid region.

Efficient utilization of available water resources requires appropriate management strategies considering the changing environmental conditions. The present study used a widely adopted crop water requirement estimation model-CROPWAT 8.0 for estimation and scheduling of irrigation requirement for onion crop grown under Vertisol in the Rabi season in the semi-arid region of Raichur district. The soil moisture at the root zone was not allowed to fall below 50% depletion. The irrigation events brought the soil moisture back to the field capacity level. The total water requirement for the 1st and 2nd seasons was 428.77 mm and 399.98 mm respectively at 90% irrigation efficiency. CROPWAT based two days irrigation scheduling scenario was found to be appropriate to maintain optimal soil moisture range within the crop root zone at different crop stages.

Scarcity of water is the most severe constraint for sustainable development of agriculture in arid and semi-arid areas. Hence, novel irrigation water application systems need to be developed so that high crop yield and water productivity per unit of land can be increased. Thus, the field experiment was conducted with the objective of determining the effect of different soil moisture depletion levels on yield and water use efficiency of sorghum crop in Benna-Tsemay woreda at Enchete kebele, Southern Ethiopia. The experiment was conducted for two consecutive years (2019-2020). It was arranged in RCBD with three replications and treatment was rated for five levels of available soil moisture depletion (ASMD), where T1 = 60%, T2 = 80%, T3 = 100%, T4 = 120%, and T5 = 140% of ASMD. Analysis of variance has shown that yield and water use efficiency of sorghum crop was significantly (P < 0.05) affected by irrigation scheduling. As observed in this study, the most economically attractive and environmentally accepted for small scale farmers with tolerable cost of production and higher net benefit was obtained by application of T3 (100% ASMD) under conventional furrow irrigation system. Therefore, for this particular sorghum crop (teshale variety), it could be concluded that increased water saving and water productivity through irrigation at 100% ASMD under conventional furrow irrigation system can solve the problem of water shortage and would ensure the opportunity of further irrigation development in the study area and similar agro-ecology.

Causas da variação em produtividade e qualidade do melão em ARGISSOLO Vermelho-Amarelo  Neyton de Oliveira Miranda1; Teógenes Senna de Oliveira2; Sérgio Luiz Aguilar Levien1; José de Arimatéa de Matos11Departamento de Ciências Ambientais, Universidade Federal Rural do Semi-Árido, Mossoró, RN, [email protected] de Ciências do Solo, Universidade Federal do Ceará, Fortaleza, CE  1 RESUMO             O trabalho foi realizado em área de produção comercial de melão, em Mossoró, RN, para identificar variáveis da fertirrigação e atributos físicos e químicos do solo influenciando a produtividade e qualidade de frutos. Foram realizadas determinações de: produtividade (frutos tipo exportação e comerciáveis); qualidade de frutos (conteúdo de sólidos solúveis totais e firmeza de polpa); da fertirrigação (vazão, elevação, distância desde a entrada de água e quantidade de adubo aplicada); de características químicas do solo (pH, matéria orgânica, Ca2+, Mg 2+, K+e Na+, acidez potencial, P disponível, Cu, Zn, Fe e Mn) e físicas (teores de argila, areia e silte, densidade do solo e umidade nas tensões de 5 e 10 kPa). Para a análise dos dados utilizou-se a estatística descritiva, a correlação de Spearman e regressão múltipla. A produtividade do melão foi prejudicada pelo excesso de água e adubo, enquanto teores de areia, ligados a menor umidade no solo, favoreceram a qualidade de frutos. O pH do solo influenciou positivamente a produtividade tipo exportação e sólidos solúveis totais. Os maiores teores de Mg favoreceram a cultura, corrigindo o desequilíbrio na relação K:Ca:Mg. Os altos teores de micronutrientes no solo foram prejudiciais à cultura, com exceção do Zn. unitermos: Cucumis melo L., propriedades do solo, fertirrigação  MIRANDA, N. de O.; OLIVEIRA, T. S. de; LEVIEN, S. L. A.; MATOS, J. de A. de.CAUSES OF VARIATION ON MELON YIELD AND QUALITY IN AN ULTISOL  2 abstract One drip fertirrigated melon production cycle was monitored in an ultisol inMossoro, RN,Brazil, to identify soil and fertirrigation variables influencing yield and quality. The following variables were measured: yield (export type and marketable fruits); quality (total soluble solid contents and fruit pulp firmness); fertirrigation (emitter discharge rate, elevation, distance to water inlet and applied fertilizer amount); soil chemical properties (pH, organic matter, Ca, Mg, K, Na, potential acidity, available P, Cu, Zn, Fe and Mn) and physical properties (contents of clay, sand and silt, soil density and soil moisture at 5 and 10 kPa). Data analysis was carried out through descriptive statistics, Spearman’s correlation and multiple regressions. Applied water and nutrient excess had negative influence on melon yield, whereas soil sand content favored fruit quality. Soil pH had a positive influence on export type yield and total soluble solid content. Melon yield and quality were improved by high Mg contents, which corrected an unbalanced soil K:Ca:Mg ratio. High soil micronutrient contents were harmful to the crop, except for Zn. KEYWORDS: Cucumis melo L., soil properties, fertirrigation.
