Pigeonpea Ratooning Trial Under Conservation Agriculture

This study contains data generated from the on-station trial that was conducted to evaluate the various management methods that are being advocated in the region. The following treatments were used for this trial.
<ol>

<li> Sole maize continuous </li>
<li> Full Pigeonpea/maize rotation </li>
<li> Maize + Pigeonpea full growth no ratooning </li>
<li> Maize + Pigeonpea, uprooting at harvest and re-seeding every year </li>
<li> Maize + Pigeonpea, ratooning at harvest and at seeding </li>
<li>. Maize + Pigeonpea, ratooning at harvest and 2 weeks after maize seeding </li>
<li> Maize + Pigeonpea, ratooning at harvest and 3 weeks after maize seeding </li>
<li> Maize + cut Pigeonpea from last season at ground level 2 weeks after maize
planting and reseed </li>
<li> Maize + delay planting of maize by a minimum of 14 days, cut Pigeonpea at base, reseed Pigeonpea with maize 14 days after the planting window. </li></ol>

本研究包含为评估该地区当前推广的各类种植管理模式而开展的田间定位试验所生成的数据。本次试验采用了以下处理方案：
1. 单作玉米连作
2. 木豆（Pigeonpea）与玉米全轮作
3. 玉米+木豆全生育期共生，不进行宿根再生
4. 玉米+木豆，收获时拔除植株，每年重新播种
5. 玉米+木豆，收获及播种时进行宿根再生
6. 玉米+木豆，收获后及玉米播种后2周进行宿根再生
7. 玉米+木豆，收获后及玉米播种后3周进行宿根再生
8. 玉米+木豆：玉米种植后2周，从地面处砍伐上一季留存的木豆并重新播种
9. 将玉米播种时间至少延迟14天，在常规播种窗口期后14天砍伐木豆基部，并将木豆与玉米一同重新播种
