The datasets used and/or analyzed during the current study will be available from the corresponding author on reasonable request. Number of primary branches per plant: the number of primary branches of randomly selected 10 plants from each plot was recorded. When using cages for tomatoes, peppers and eggplants, add a little extra space for convenience. The fruits were counted at each harvest time, averaged converted to number of marketable fruits per hectare, and expressed in numbersUnmarketable fruit number per hectare: fruits with cracks, rotting, damage by insects, diseases, and birds, and sunburn, as well as extra small-sized fruits, were collected from ten tagged plants and were considered as unmarketable. Results indicated that the number of pods plants-1 and grain yield/ha-1 of Bambara groundnuts increased with increased planting density. between intra row spacing and variety showed that the use of wider row spacing in combination with the varieties improved the plant height, stem girth and number of pods significantly. Performance of some bean (Phaseolus Vulgaris L.) varieties under different irrigation systems and regimes. In the study area, little information is available on plant spacing of the newly released semi-indeterminate variety of tomato called Weyno. This is one of the factors which lead to low yield and less quality production. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 12. Cary, NC: SAS Institute, Inc.; 2002. This is an open access article distributed under the. Results from the analysis of variance showed that both the main effect and their interaction effect of inter- and intra-row spacing were highly significant (P<0.01) on the number of branches per plant at Metema site two (Table4), whereas, at site one, the main effect was significant (P<0.01), while their interaction had no significant effect on the number of branches per plant (Table4). Texcoco: CIMMYT (International Maize and Wheat Improvement Center); 1988 (completely revised edition). Fruit diameter (cm): the diameter of 10 randomly selected fruits per each plot at each harvest was measured using a caliper meter, and their average is expressed as fruit diameter. 6:55-59. doi/abs/10.2135/cropsci1966.0011183X000600010017x. W. T. Kelley and G. Boyhan, Commercial Tomato Production Hand Book, The University of Georgia and Ft, Valley State University, Fort Valley, GA, USA, 2010. Palmer amaranth is a highly competitive broadleaf weed, able to grow much faster than most soybean cultivars in warm regions. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. 12, no. In some cases, multiple postemergence herbicide treatments are not needed due to the weed suppression caused by soybean competition. December 2009 to April 2010 cropping season to assess the effects of intra-row spacing and variety on yield and yield components of potato (Solanum tuberosum L.). The combined main effect of intra- and inter-row spacing had a significant (P<0.01) effect on harvest index (Table1). (g/plant) and final yield (3.00 ton/ha). [PDF] Effect of Levels of Nitrogen Fertilizers and Intra Row Spacing on The maximum plant height (79.83 cm) was recorded at inter-row spacing of 20, 30 and 40 cm (Table 2 ). Crop spacing refers to the number of crops that can be planted in one area. If, however, the intra-row has much miss-spacing, it may indicate low-vigor seeds or a poorly adjusted machine. East-west row orientation is preferred to maximize light absorption, but this is not always possible. Khan EA, Aslam M, Ahmad HK, Ayaz M, Hussain A. Not applicable since the study involved mung bean plants. Disease Severity: Disease is another troublesome variable that can adversely affect soybean fields. The increase in yield was variety-dependent, thus suggesting that the genetic potential of the varieties needs to be considered when using plant density to increase yields. Fruit diameter was significantly (<0.05) affected (<0.01) by the main effect of interrow and intrarow spacing (Table 1), whereas the interaction effect of intra- and interrow spacing was not significant. According to Gemechis et al. The highest number of pods per plant (26.73) was obtained from 5015cm inter- and intra-row spacing, while the lowest number of pods per plant (7.53) was found at 205cm at Metema site two (Table6). Animal and Plant Health Regulatory Directorate, Issue No. The treatments consisted of factorial combinations of three each of inter and intra spacing of 50, 75 and 100cm . How do you calculate the spacing of a plant population? Row Spacing - Getting Rid Of Weeds PDF EFFECT OF INTRA ROW SPACING AND VARIETY ON THE GROWTH - ResearchGate Plant height (cm): the plant height was measured from the base of the plants to the terminal growing point of the main stem at the end of the third harvest. What is difference between mixed cropping and intercropping? With regard to the effects of intra-row spacing, the maximum plant height (80.43 cm) was recorded at narrow intra-row spacing of 5 cm (Table 2 ). Animal and Plant Health Regulatory Directorate, Issue No. There is a considerable difference in the life cycle and the duration of maturity in different crops, All crops have a similar life cycle and duration of maturity. In many cases, the topography that includes the shape, terrain, and slope of the land, as well as the location of existing vegetation, roads, irrigation lines, buildings, and physical barriers, dictates the row orientation. Data were collected on the following:Plant height (cm): the plant height was measured from the base of the plants to the terminal growing point of the main stem at the end of the third harvest. In Ethiopia, tomato is the main source of income and food security in most rift valley areas. PDF Effect of Nitrogen Rate and Intra-Row Spacing on Yield Components and It is found at about 225km northeast of Addis Ababa. Box 1937, Woreta, Ethiopia, Department of Plant Sciences, University of Gondar, P.O. maximum growth of potato were observed for all treatments at the application rate of 138kg nitrogen per hectare and50cm intra row spacing except main stem number (10.22) which is at 30 cm, However the results of the experiment did Besides, at spacing of 20cm5cm, the grain yield ha1 was significantly higher as compared to the interaction of wider inter- and intra-row spacing (5015cm), which showed that the main determinant of yield was the plant population which along with other yield attributes contributed toward a significant increase in grain yield (Table7).
