In most cases it is a good idea to leave at least 18 to 36 inches of space between each row of plants. Ara et al. Results indicated that intrarow and interrow spacing had a nonsignificant (>0.05) effect on the number of primary branches (Table 1). This website is copyrighted under Creative Commons-Attribution. Weeds compete with crops for essential resources (sunlight, nutrients, water, and space); if they outcompete the crop this can lead to significant yield loss. The experiment was laid in a randomized complete block design with three replications in a factorial arrangement of four inter-row (20, 30, 40 and 50 cm) and three intra-row (5, 10 and 15 . SAS Version 9.1 20012002. What is the difference in seed spacing and plant spacing? The highest number of unmarketable and marketable fruit was recorded from a closer spacing of 60cm followed by 80cm interrow spacing with no significant difference in between. Weed seed production can replenish the soil seedbank with new seeds, which can be a problem in the following years. Animal and Plant Health Regulatory Directorate, Issue No. Also, inter-row cultivation can stimulate emergence of some weed species. How do you calculate the spacing of a plant population? The highest grain yield (1882.67kgha1) was obtained at interaction of 4010cm spacing, while the lowest (1367.8kgha1) was obtained from 205cm spacing. 133, no. The fruits were counted at each harvest time and expressed in numbers and converted to number of unmarketable fruits per hectare. Planting was done when there was adequate soil moisture in the field. Mehmet OZ. The reverse is true for Sefinesh. There is also evidence that narrow rows may promote disease incidence in susceptible crops. [25] who stated that no significant effect of different row spacing and plant densities on pod length of mung bean. Harder, D.B., Sprague, C.L., Renner, K.A. Opposite to these results, Agele et al. Data are available on request from Getchew Amare and Hailay G/medhin (e-mail: [emailprotected]). PDF Effect of Nitrogen Rate and Intra-Row Spacing on Yield Components and Crop Management 5(1).
