Crop Productivity, Economic Advantage, and Photosynthetic Characteristics in a Corn-Peanut Intercropping System

چکیده
Corn-peanut intercropping is an important element of China’s agricultural planting model as it confers ecological benefits and increases yield. The aim this study was to explore the productivity differences between monoculture by using 13C isotope tracer labelling method. Corn hybrid Denghai 618 (DH618) peanut variety Huayu 22 (HY22) were used test materials under three methods, single corn, SM; peanut, SP; corn-peanut intercropping, IM IP, respectively, during two growing seasons. results showed that increased yield 59.7% 62.3% compared with SM, respectively. IP reduced 31.3% 32.3% SP, significantly photosynthetic rate, leaf area, assimilation distribution, dry matter accumulation summer which led increase in kernel number grain decrease intercropped mainly caused a full-pod rate pods per plant. did not affect production benefit due larger advantage land equivalence ratio. yielded greater economic than monoculture. These utility peanut-corn model.

متن کاملWeed Control via Intercropping with Gliricidia. Ii. Corn Crop
A reduction in herbicide use is one of modern agriculture’s main interests and several alternatives are being investigated with this objective, including intercropping. Gliricídia (Gliricidia sepium) mulch has no allelopathic effect on corn or beans but significantly decreased the population of some weed species. The objective of this study was to evaluate green ear and grain yield in corn cult...

The objective of this study was to evaluate the effects of sowing procedures and the seed sowing rate of kudzu (Pueraria phaseoloides cv. ‘Comum’) in corn on corn plant development, forage dry matter production, weed infestation and soybean plant development and yield. The kudzu seeds were either broadcasted over the terrain or sown in furrows (in the main plots) at rates, in both cases, of 400...
