灌溉土壤晒后7周，10 cm土层温度比对照提高11.5℃，有效地控制了玉米杂草(98.5%)、二化螟(8.9%)和玉米茎腐病(69.1%)。日晒还显著减轻串珠镰刀菌和菜豆大斑病的症状，分别减少64.2%和78.4%，完全控制了玉米品种的串珠镰刀菌和菜豆大斑病。Pool-10，Shaheen和Gauher除沙欣和阿克巴尔两个品种外，其余品种均未发现禾谷镰刀菌。日光下种植的作物生长较好，籽粒产量几乎是供试品种的一到三倍。日晒后立即进行的土壤分析表明，必需元素以更简单的形式很容易获得，这可能提高了抗虫性，减少了秸秆折断。
Seven weeks solarization of irrigated soil raised its temperature by 11.5 degrees C over non-solarized soil at 10 cm depth and effectively controlled weeds (98.5%), stalk borer (8.9%) and stalk rot disease (69.1%) in corn. Solarization also reduced symptoms of Fusarium moniliforme and Macrophomina phaseolina significantly by 64.2% and 78.4% respectively, and completely controlled M. phaseolina in corn cultivars, viz. Pool-10, Shaheen and Gauher. Whereas symptoms of F. moniliforme were observed in these cultivars, Fusarium graminearum was not observed except in two cultivars, Shaheen and Akbar. Growth of crop planted in solarized plots was better and it yielded almost one to three times more grains in cultivars under test. Soil analysis immediately following solarization revealed that essential elements were readily available in simpler forms, which may have increased pest resistance and reduced stalk breakage.
