Impact of tillage and intra-row spacing on cotton yield and quality in wheat–cotton system

Garlic is primarily grown for its cloves used mostly as a food flavoring condiment. Previous studies carried out on plant density indicate its direct influence on yield. Plant density depends on the genotype, environmental factors, cultural practices, etc. This study was established to determine the effects of different between-row spacing on growth, yield, and quality of four local accession of garlic. It was laid out on two-factorial Randomized Complete Block Design with three replications during two years. Four local accession of garlic (Langroud, Tarom, Tabriz and Hamedan) were culture in three between-rows spacing (15, 25 and 35 cm) during two years. The results of two cultivated years were different. Plant density changed when garlic cultured with different between row spacing. In present research plant yield increased when the lower between row spacing and high plant density were used but the yield improvement occurring at increased plant stand is offset by the reduction in bulb size and some quality indices such as total phenol and antioxidant which severely affects quality and market value, when garlic is produced for fresh market.

Seed Yields

To obtain high chia seed yields and seed qualities, a suitable crop management system needs to be developed for the given growing conditions in southwestern Germany. Field experiments were conducted at the experimental station Ihinger Hof in two consecutive years (2016, 2017). The study aimed to evaluate yield and quality traits of chia depending on different (i) row spacing (35, 50 and 75 cm), (ii) sowing densities (1, 1.5 and 2 kg ha−1) and, (iii) N-fertilization rates (0, 20 and 40 kg N ha−1). It consisted of three independent, completely randomized field experiments with three replications. Results showed that chia seed yields ranged from 618.39 to 1171.33 kg ha−1 and that a thousand seed mass of 1.14 to 1.24 g could be obtained. Crude protein-, crude oil- and mucilage contents varied from 18.11–23.91%, 32.16–33.78% and 10.00–13.74%, respectively. Results indicated that the year of cultivation and the accompanied environmental conditions, like precipitation or temperature, influenced the determined traits more than the applied agronomic practices. As average seed yields exceeded those obtained in the countries of origin (Mexico, Guatemala) while having comparable quality characteristics, chia holds great potential as an alternative crop for farmers in southwestern Germany.

Number Of Branches

The productivity of tomato is influenced mainly by environmental factors, agronomic practices and cultivar potential. Accordingly, a field experiment was conducted at Mizan-Aman, southern Ethiopia in 2016/ 2017 to evaluate the effect of intra-row spacing (20, 30, 40 and 50 cm) on the performance of three tomato varieties(Fetan, Bishola and Roma VF) with the constant inter-row spacing of 70 cm in completely randomized block design with three replications. Data on crop phenology, growth performance, yield and quality parameters were recorded and subjected to analysis of variance using SAS version-9 software. Results of the study indicated that both intra-row spacing and variety had a significant effect on phenology as well as parameters including; the number of branches, the number of fruit cluster and fruit per plant, fruit weight, total fruit yield, marketable and unmarketable yield and total soluble solids (TSS). However, the number of fruits per cluster, fruit shape index, titratable acidity (TA) and pH were significantly different only among varieties, while plant height was significantly affected by intra-row spacing. Closer spacing enhanced early maturity, while wider intra-row (50 cm) produced a maximum number of branches, cluster and fruits per plant, fruit weight, unmarketable yield and TSS. Generally, 20 and 30 cm intra-row spacing was found to be suitable for the production of maximum total and marketable yield. From the three tomato varieties, Fetan was early maturing with the highest total and marketable yield. The varieties were also significantly different in fruit weight, with the highest value obtained from Bishola followed by Fetan. The outcome of this study revealed that, the intra-row spacing of.30 cm and variety Fetan could be promoted for production in Mizan-Aman and similar agro-ecologies.

Location Interaction

The goals of these studies were to determine how miniwatermelon (Citrullus lanatus) cultivars differed and responded to plant in-row spacing in terms of percentage of marketable fruit and yields, and if plant spacing impacted internal fruit quality. Three genetically diverse triploid miniwatermelon cultivars (Mohican, Petite Perfection, and Xite) were selected. These cultivars were evaluated in field locations at northern Florida (Quincy), central South Carolina (Blackville), coastal South Carolina (Charleston), and eastern North Carolina (Kinston) at five within-row distances. Within-row distance included 9, 12, 15, 18, and 21 inches. All plots were15 ft long with row middles 9 ft apart. Fruit were categorized as marketable if they weighed between 3.1 and 9.0 lb per fruit. Within this range further categories were divided as follows: ≤3.0 lb (cull), 3.1 to 5.0 lb (small), 5.1 to 7.0 lb (average), 7.1 to 9.0 lb (large), and ≥9.1 lb (cull). There was a cultivar by location interaction, suggesting that the three cultivars responded differently at each of the four locations. ‘Petite Perfection’ was among the highest yielding at all locations except Quincy, where it was the lowest yielding cultivar. As with total yields, the percentage of marketable fruit was similar for some cultivars across locations. Cultivar Petite Perfection produced the highest percentage of marketable fruit at three of the four locations. The exception was the Quincy site where ‘Xite’ had the highest percentage of marketable fruit. Within-row plant distances and populations affected total marketable yield, both for fruit weight and number per plant, regardless of cultivar and location. As the plant population increased from eight plants per plot (21-inch in-row spacing) to 12 plants per plot (15-inch in-row spacing), total marketable miniwatermelon fruit yields increased in total fruit number as well as total weight. There was a cultivar by location interaction for the percentage of soluble solids and the rind thickness measurements, suggesting that some cultivars responded differently at each of the four locations. Quality effects were more apparent with ‘Mohican’ and ‘Xite’, as they were more responsive to location than ‘Petite Perfection’.
