Productive potential of watermelon under different plant spacings in the semi-arid region of Brazil

Abstract

This study aimed to evaluate the growth and development of watermelon plants under different plant spacings in the Semi-arid region of Brazil. A randomized block experimental design was used with four treatments and eight replications. Data were submitted to analysis of variance and the Tukey test. The treatments were composed by the following spacings: T1: 3.0 x 0.8 m; T2: 3.0 x 0.6 m; T3: 2.0 x 0.8 m and T4: 2.0 x 0.6 m (spacings between rows and between plants, respectively). The plant length, number of leaves, stem diameter, leaf area, number of flowers, number of fruits per plant, average fruit weight, total fruit production, number of commercial fruits, average weight of commercial fruits, total weight of commercial fruits and percentage of commercial fruits were evaluated in this study. There was a significant difference in the growth traits: stem diameter and leaf area at 30 days after sowing (DAS), and plant length, stem diameter and number of leaves at 60 DAS, with no significant statistical difference in the remaining days and nor for the number of flowers. The watermelon plants showed adequate vegetative and productive development at the 2.0 x 0.8 m plant spacing in the edaphoclimatic conditions of the semi-arid region under study. This spacing is well suited to small producers in the semi-arid region, which are dependent on agriculture with small areas and can obtain good productivity with no need to use larger areas due to spacing

Effect of crop geometry, fruit thinning and nutrient management on growth parameters of watermelon (Citrullus lanatus Thumb.)

“…The result is in line with the findings of Gomes et al (2017) [34] . and da Silva et al (2021) [35] in watermelon. The increase in leaf area due to fruit thinning may be attributed to the better vegetative growth recorded.…”

“…Further studying the interactions, D 3 F 2 N 3 (T 31 ) recorded the highest LAI of 0.48 and D 1 F 1 N 1 (T 1 ) recorded the least of 0.11. Interactions of D 3 F 1 N 3 (T 27 ) and D 3 F 2 N 3 (T 35 ) recorded values at par with D 3 F 2 N 3 (T 31 ). The significant variations in interaction may be the result of cumulative effect of all the three factors together.…”

The Sources of Supply of Fruits and Vegetables in Novi Sad (Serbia)

“…Vegetables found with South American origins are watermelons and melons. Brazilian watermelons from the distant provinces of Bahia and Rio Grande do Norte (Silva, et al, 2021) first precede, and then are simultaneously offered with those originating from the region of Southeast Europe (Northern Macedonia, Albania, Greece, etc.). The market position of vegetables will still be fluctuations and variability of their prices over the years (Mihajlović, Vukelić, Novković, & Mutavdžić, 2019).…”

Evaluasi Frekuensi Penanaman Tanaman Semangka (Citrullus lanatus) Terhadap Keparahan Penyakit dan Produktivitas Tanaman Semangka

“…Ada beberapa faktor yang menyebabkan terkendalanya produktivitas tanaman semangka. Faktor tersebut adalah pH tanah (5.6-8), kemampuan dan pengalaman petani dalam mengelola lahan semangka seperti pemilihan benih, jarak tanam (Da Silva et al, 2021), pupuk, dan penggunaan pestisida serta polinasi, hama dan penyakit seperti antaknosa, layu fusarium dan serangan virus (Damicone & Brandenberger, 2020), Serta tipe lahan yang digunakan dan suplai air (Tunde, 2019).…”
