Weeding is critical to eliminate non-native plants that compete with main crops and adversely affect their production quality and quantity. Numerous prototypes exist for inter-row weeding but very limited for intra-row weed eradication. This study developed a tractor drawn integrated inter- and intra-row weeding (IIIRW) system for field crops. Active rotary tines were used for intra-row weeding and passive tines for inter-row weeding. Optimum operational configurations were obtained with rigorous repeated soil bin experiments, and developed system was evaluated for three growing seasons (2017–19) in field grown maize (Zea mays L.) and pigeon pea (Cajanus cajan (L.) Millsp.) crops. Optimum ratios of intra-row tine rotary speed to forward speed (u/v) were in the ranges of 0.8–1.3 that lead to weed mortality of 88.4 % (Buried: 8.5 %, Uprooted: 79.9 %), negligible intact weeds, and plant damage (P_d) within 6 %. Sole inter-row weeding operation resulted up to 78.1 % of weed mortality (Buried: 18.1 %, Uprooted: 60.0 %) and negligible P_d. Overall weed mortality with the IIIRW system was 92.8 % (Buried: 9.5 %, Uprooted: 83.3 %) in maize and 84.1 % (Buried: 7.6 %, Uprooted: 76.5 %) in pigeon pea crops. Results suggest suitability of the IIIRW system for a range of similar crops for field capacity in ranges of 0.22–0.26 ha/h at recommended operating speeds within 0.50–0.56 m/s. The IIIRW system requires a single prime mover and could be potentially economical and efficient technology for field weeding operations.

除草对于消除与主要农作物竞争并对其生产质量和数量产生不利影响的非本地植物至关重要。行间除草的原型很多，但行内除草的原型非常有限。这项研究开发了拖拉机牵引的大田作物行间和行内除草（IIIRW）系统。主动旋转式尖齿用于行内除草，被动式尖齿用于行间除草。通过严格的重复土壤箱实验获得了最佳的操作配置，并在田间种植的玉米（Zea mays L.）和木豆（Cajanus cajan（L.）Millsp 。）作物的三个生长季节（2017-19）评估了开发的系统。行内齿形转速与前进速度的最佳比率（u / v）在0.8-1.3范围内，导致杂草死亡率为88.4％（埋葬：8.5％，连根拔起：79.9％），完整杂草可忽略不计，植物危害（P _d）在6％以内。行间除草操作可导致高达78.1％的杂草死亡率（埋葬：18.1％，连根拔起：60.0％），P _d可忽略不计。在玉米和豌豆农作物中，IIIRW系统的总杂草死亡率为玉米的92.8％（埋葬：9.5％，连根拔起：83.3％）和84.1％（埋入：7.6％，连根拔起：76.5％）。结果表明，IIIRWRW系统适用于一系列类似农作物，田间处理能力为0.22-0.26 ha / h，推荐操作速度为0.50-0.56 m / s。IIIRW系统仅需一个原动机，并且对于田间除草操作而言可能是一种潜在的经济高效的技术。
