“…This showed the level of compatibility of this cropping mixture in this study. Our finding did not agree with Tenywa et al (2016) who reported that East-W est row orientation resulted in a greater groundnut yield by up to 50%, than those facing North-South in sorghum groundnut intercropped at Uganda. Research by Kuldeep and Sharma (2019) also reported that sowing in a North-South direction resulted in a higher wheat grain yield than sowing in an East-West orientation.…”

Background: Intercropping and row arrangement represent a dynamic frontier of research and practical application, influencing resource allocation, weed competition and overall crop productivity in a modern agro ecosystem. This study aimed to investigate the impact of row orientation and arrangement on weed competition and crop performance within the Sudan savannah ecology of Nigeria during the 2018 rainy season. Methods: A field experiment was conducted at BUK (Latitude 11°58'N and Longitude 8°25'E) and Minjibir (Latitude 12.14590N and Longitude 0.866'4850E), utilizing two orientations (East-West and North-South) and seven sorghum: groundnut row arrangements (1:1, 1:2, 2:1, 2:2, 3:3, 2:4 and 4:2). A randomized complete block design with three replications was used, with simultaneous cultivation of SAMSORG 40 sorghum and SAMNUT 24 groundnut varieties. Result: The 2:1 row arrangement exhibited the lowest weed density (23.2 and 31.1 m-2) and dry weight (408.6 and 438.2 kg ha-1). East-West orientation reduced weed density by 24.5% at BUK and 20.8% at Minjibir. North-South row orientation significantly increased sorghum grain yield by 17.7% and reduced groundnut kernel yield by 9.37%. Higher sorghum yield (699.6 and 773. 7 Kg ha-1) was observed with 2:1 whereas the 1:2 arrangement yielded more groundnut kernels (329.2 and 338.1 kg ha-1). East-West orientation and the 2:1 row arrangement suppressed weed growth and recorded higher yields.

“…The shortest average plant height of 48.8 cm was recorded for the control plots without N fertilization. Gohari and Niyaki (2010), and Tenywa et al (2016) reported that the application of N fertilizer remarkably increased the plant height of groundnut. Nitrogen fertilizer has a pronounced effect on the plant height of pea due to increased growth performances (Achakzai, 2012).…”

Increasing costs of chemical fertilizers, environmental concerns of their application and demand for protein foods, placed an extensive interest in growing of legume crops for human nutrition, and soil fertility replenishment. This study was conducted to investigate the effects of nitrogen (N) and phosphorus (P) fertilizers on parameters of phenology, growth performance, grain yield, yield components, grain protein content of groundnut, and residual soil nitrogen content in the northern Ethiopia during the growing season of 2017. Three levels of N (0, 15 and 30 kg ha −1 ) and four levels of P 2 O 5 (0, 23, 46 and 69 kg ha −1 ) were set in factorial combinations of randomized complete block design with three replications. Results showed that an average total biomass yield increased by 22.5% for separate individual application of 15 kg N ha −1 and by 16.6% for 46 kg P 2 O 5 ha −1 compared to control plots. Haulm yield increased by 29.17% for plots treated with N fertilization compared to control plots. Average pod yield increased by 85.4% for a combined application of 15 kg N ha −1 and 46 kg P 2 O 5 ha −1 fertilizers compared to the control plots. Plots fertilized with the highest combined rates of N and P have attained lower grain yield compared to the combined application of 15 kg N ha −1 and 46 kg P 2 O 5 ha −1 . The highest grain protein contents were obtained for a combined application of 30 kg N ha −1 and zero P, and 15 kg N ha −1 plus 46 kg P 2 O 5 ha −1 . The highest N harvest index was obtained for control treatments and for plots treated with combined application of 15 kg N ha −1 and 46 kg P 2 O 5 ha −1 . Residual soil N content increased by 119% on plots with combined application of 15 kg N ha −1 and 46 P 2 O 5 ha −1 compared to control plots. Based on our results, combined application of 15 kg N ha −1 and 46 kg P 2 O 5 ha −1 was recommended for increasing grain yield, grain protein content and residual soil nitrogen. The results of this study are crucial to improve groundnut productivity, grain protein content and also to provide implication on soil fertility management in a crop rotation system.
