“…Crusier with TNT protection up to 10, 20 and 32 days after planting (DAP) resulted in earlier plants with higher marketable and total yields compared to the control, without the protection. In Baraúna, Rio Grande do Norte state, Medeiros et al (2007), keeping the Cantaloupe melon 'Torreon' protected with TNT up to 28 DAT verified a significant increase of 16.43% and 12.96%, respectively, in the number of total and marketable fruits. The different productive performance of the Cantaloupe melon protected temporarily with TNT in different regions, including this study, can be explained by the genotype x environment interaction.…”

“…In Brazil, some studies have shown the importance of knowledge about the growth and physiological indices as well as the influence of agronomic practices and external factors on the final production of the plant (Medeiros et al, 2006(Medeiros et al, , 2007Morais et al, 2008), however studies related to this subject about the delay of removing the row cover, as a resource to change the source-drain ratios in melon production, are not common.…”

In Rio Grande do Norte, the melon growers have been using the row cover on the roof of the plants to start flowering in order to reduce the population of insect pests that cause severe losses, rising production costs, especially with the application of defensive. Thus, it is important to know the best time to remove the row cover because, due to its use, it is assumed that there are changes in the physiological response of plants. In order to evaluate the growth and yield of the melon plants 'Acclaim' cultivated under protection agrotextile (TNT) for different periods, a trial was conducted at the Universidade Federal Rural do Semi-árido, Mossoró, Rio Grande do Norte state. The experimental design was a randomized complete block, with four replications, in a splitplot, the plots were the plant protection periods (0, 18, 21, 24, 27 and 30 days after transplanting, DAT), and splitplots, times of sampling the plants (13, 20, 27, 34, 41, 48 and 55 DAT). We evaluated the dry matter accumulation in leaves (LDMA), branches (BDMA), flowers (FDMA), fruits (FrdMA) and total (TDMA), assimilate partitioning, leaf area index (LAI), leaf weight ratio (LWR), absolute growth rate (AGR) and relative (RGR), net assimilation rate (NAR), total (PTOT) and marketable productivity (PCOM). The treatments with plant protection did not affect the TDMA which peaked at 295.12 g plant -1 at 53 DAT, with the fruits behaving like sink preferred plant, accounting for 72.25% of the dry mass accumulated. The LAI and the AGR grew by 55 and 42 DAT (1.95 and 18.518 g/plant/day), respectively, while the LWR and RGR decreased over the cycle, with peaks of 0.911 and 0.242 g/g/day, at 13 and 20 DAT, respectively. The PTOT and PCOM were not affected by periods of plant protection, with averages of 29.30 and 22.25 t ha -1 , respectively, indicating that it is possible to manage the row cover in order to remove it later, that reduces costs and crop protection without significant loss in productivity.

“…The necessary condition for success in growing this plant is directly related to high luminosity, temperature, low rainfall and low relative humidity (Medeiros et al, 2007). These weather conditions are found in Sertão Region of the State of Paraíba, however, due to low level of technology and inappropriate plant management adopted by small producers, the production has been low.…”

Characteristics of muskmelon fruits in relation to temporary row cover and the number of fruits

et al. 2017

The muskmelon plants allow several ways to manipulate sources/ drains ratio. The objective of this work was to evaluate characteristics of the productivity and quality of Cantaloupe melon fruits due to the temporary use of row cover and the number of fruits per plant. The experiment was carried out from August to December 2014, at Universidade Federal de Campina Grande (UFCG), Paraiba State, Brazil. The experimental design was randomized blocks with treatments allocated in split plots 5x3, with four replicates. The authors reported permanence time of the row cover at different times in the plot [20, 24, 28, 32, and 36 days after transplanting (DAT)] and, in the subplots, the number of fruits per plant (plants with one fruit, plants with two fruits and fruit-free setting plants). The authors evaluated traits of production and quality of fruits. The permanence time of row cover and number of fruits per plant promoted changes in the productivity and quality of the muskmelon fruits. The permanence of the row cover from 20 to 36 DAT provided reduction in the total soluble solids. The average fruit mass and fruit yield reached the maximum value with the permanence of the row cover up to 26.6 and 25.1 DAT, respectively. Plants with one and two fruits presented higher average fruit mass, but with lower productivity compared to the plant with fruit-free setting.

“…Embora os filmes plásticos de polietileno sejam amplamente utilizados como mulching em diversas hortaliças, o tecido de polipropileno ou agrotêxtil (TNT) tem sido empregado como manta sobre as plantas de melão e melancia (Medeiros et al, 2007;Dantas et al, 2009) mas também, recentemente como cobertura do solo, proporcionando aumento de produção e diminuindo a incidência de plantas daninhas, em hortaliças como a alface (Reghin et al, 2002) e maior produtividade de frutos comerciais no cultivo do tomate (Factor et al, 2009).…”

Growth analysis of tomato plants 'SM-16' cultivated under different mulchingIn order to evaluate the growth of tomato plants cv. SM-16, grown under different mulching, a trial was carried out at WG Fruticultura, Baraúna, Rio Grande do Norte state, Brazil, between July and November 2008. The experimental design was arranged in splitplots, under completely randomized blocks with four replications. Treatments (plots) were the mulching types: uncovered soil, black polyethylene film, silver polyethylene film, white polyethylene film and black polypropylene TNT, and the splitplots were sampling times: 14, 28, 42, 56, 70, 84 and 98 days after transplanting (DAT). Dry mass accumulation in leaves (AMSF), branches (AMSR), inflorescences (AMSI), fruits (AMSFR) and total (AMST), leaf area index (IAF), leaf area ratio (RAF), specific leaf area (AFE), absolute growth rate (TCA), relative growth rate (TCR) and net assimilation rate (TAL) were determined. The mulching influenced the development of dry matter accumulation in leaves, branches and fruits, and the TNT promoted the highest averages. The fruits behaved as the preferential drain of the plant. The TNT was the mulching that has promoted the highest average for the leaf area index and absolute and relative growth rates. The leaf area ratio, specific leaf area and net assimilation rate were not influenced by cover crops.
