Effects of Maize-Soybean Intercropping on Nitrous Oxide Emissions from a Silt Loam Soil in the North China Plain

Pedosphere 2019年第6期29卷 764-772页

作者： HUANG Jianxiong SUI Peng GAO Wansheng CHEN Yuanquan College of Agriculture and Biotechnology China Agricultural UniversityNo.2 Yuanmingyuan West RoadHaidian DistrictBeijing 100193(China Rubber Research Institute Chinese Academy of Tropical Agricultural SciencesDanzhou 571737(China

Maize ( Zea mays L.), a staple crop in the North China Plain, contributing substantially to agricultural nitrous oxide (N 2 O) emissions in this region. Many studies have focused on various agricultural management measures to reduce N 2 O emissions. However, few have investigated soil N 2 O emissions in intercropping systems. In the current study, we investigate whether maize-soybean intercropping treatments could reduce N 2 O emission rates. Two differently configured maize-soybean intercropping treatments, 2:2 intercropping (two rows of maize and two rows of soybean, 2M2S) and 2:1 intercropping (two rows of maize and one row of soybean, 2M1S), and monocultured maize (M) and soybean (S) treatments were performed using a static chamber method. The results showed no distinct yield advantage for the intercropping systems. The total N 2 O production from the various treatments was 0.15 ± 0.04–113.85 ± 12.75 µg m −2 min −1 . The cumulative N 2 O emission from the M treatment was 16.9 ± 2.3 kg ha −1 over the entire growing season (three and a half months), which was significantly higher ( P < 0.05) than that of the 2M2S and 2M1S treatments by 36.6% and 32.2%, respectively. Two applications of nitrogen (N) fertilizer (as urea) at 240 kg N ha −1 each induced considerable soil N 2 O fluxes. Short-term N 2 O emissions (within one week after each of the two N applications) accounted for 74.4%–83.3% of the total emissions. Soil moisture, temperature, and inorganic N were significantly correlated with soil N 2 O emissions ( R 2 = 0.246–0.365, n = 192, P < 0.001). Soil nitrate (NO − )3 and moisture decreased in the intercropping treatments during the growing season. These results indicate that maize-soybean intercropping can reduce soil N 2 O emissions relative to monocultured maize.

An experiment was conducted during Kharif seasons of 2009 and 2010 on sandy loam soil of West Bengal, India to evaluate the productivity and economic viability of maize ＋ legume intercropping systems in additive as well as in replacement series with different row proportions. Maize （Zea rnays L.） cv. ＂Vijay＂（composite）, green gram （Vigna radiata L.） cv. ＂Samrat＂, black gram （Vigna mungo L.） cv. ＂Sarada＂, soybean （Glycine max L. Merril） cv. ＂PK 327＂ and peanut （Arachis hypogaea L.） cv. ＂JL 24＂, were tested in monoculture as well as in intercropping situations with 1：1 （additive series） and 1：2 ratios （replacement series）. The result indicated that intercropped legumes improved the yield components of maize and offered some bonus yield. The highest maize grain yield （2,916.28 kg/ha） and maize equivalent yield （4,831.45 kg/ha） were recorded with maize ＋ green gram （1：1） and maize ＋ peanut （1：I）, respectively. The values of all the competition functions were always greater than unity and maize ＋ black gram （1：2） recorded the highest values of land equivalent ratio （1.433）, area time equivalent ratio （1.374） and land equivalent coefficient （0.421）. Maximum monetary advantage （Rs. 10,579.13） was found with maize ＋ green gam （l：1）. Maize ＋ peanut （1：2） combination recorded the highest relative net return （2.01）, net return （Rs. 28,523.08）, benefit-cost ratio （2.76） ad per day return （Rs. 259.30）.

Cassava-groundnut intercropping is not a common practice among smallholder farmers in Sierra Leone even though both crops are well suited for intercropping. On-farm trials were conducted in three locations (Bai Largor, Bassah, and Njala Kanima) in the Moyamba district during the 2021 cropping season to investigate the efficacy of cassava-groundnut intercropping for increasing crop productivity and soil organic carbon stock on smallholder farms in the Moyamba district, Southern Sierra Leone. The experimental design was a randomized complete block design in three replications with treatments of sole groundnut, sole cassava and cassava-groundnut intercropping. Data on the yield and yield components of cassava and groundnut were analysed using the PROC MIXED procedure of SAS 9.4 and means were compared using the standard error of difference (SED). The above-ground biomass, number of roots per plant, and fresh root yield of cassava were not significantly (p > 0.05) affected by the cassava-based cropping system. Averaged across locations, intercropping cassava with groundnut decreased the above-ground biomass, the number of roots per plant, and fresh root yield of cassava by 17%, 11%, and 17%, respectively. The above-ground biomass, number of pods per plant and fresh pod yield of groundnut were significantly (p 1), the highest net revenue and benefit-cost ratio. The benefit-cost ratio was also favourable for the sole cassava (BCR > 1) but not favourable for the sole groundnut (BCR ratio by 121% and 13% when compared to the sole groundnut and sole cassava. In the event of a 40% yield loss for the cassava and groundnut, the benefit-cost ratio was favourable (1.12) only for the cassava groundnut intercropping system. The net soil organic carbon stock was favourable only for the cassava-groundnut intercrop. Averaged across locations, the net soil organic carbon for the cassava-gro

Analysis on Waxy Corn/Soybean Intercropping Pattern and Economic Benefit

引用

Agricultural Science & Technology 2016年第1期17卷 48-50页

作者：秦燕郭泓鋆杨进赵永康杨洪韩庆新李兰成都市农林科学院四川成都611130 仲衍种业股份有限公司四川成都610041

The research mainly analyzed effects of waxy corn/soybean intercropping on yields of the two crops, as well as agronomic characters, and the economic benefits of the mode. The results showed that although yields of waxy corn and soybean went down by 21.19% and 31.04% per unit area, land equivalent ratio（1.48） kept higher than 1, suggesting the intercropping improves land use rate. Besides, due to the practice of intercropping, many characters of waxy corn grew, but of soybean declined. The economic benefits from high to low were waxy corn/soybean intercropping, monoculture of waxy corn, and monoculture of soybean.

[Objectives]To explore the proper intercropping pattern between chewing cane and peanut.[Methods]A field experiment was carried out to investigate the yield and economic benefit of chewing cane and peanut,as well as the changes in soil properties under different chewing cane/peanut intercropping *** chewing cane/peanut intercropping patterns were designed,in which with every row of chewing cane intercropping one row of peanut(CP_(1)),intercropping two rows of peanut(CP_(2))and chewing cane mono-cropping(MC).[Results]It had no significant effect on the agronomic characters of chewing cane and peanut in CP_(1)and CP_(2),compared with *** soil properties before the planting(BP)and after the harvest(AH)indicated that the chewing cane/peanut intercropping patterns significantly increased soil organic matter and soil available nitrogen contents,but decreased soil available potassium contents,and CP_(2)had better effect on soil structure than CP_(1).The total production value and economic benefit were increased significantly on the CP_(1)and CP_(2),comparing the MC,and the benefit of CP_(2)was higher significantly than that of CP_(1).The land equivalent ratios(LER)for CP_(1)and CP_(2)were 1.94 and 1.72,respectively,which was significantly higher than that of MC(0.83).Although planting cost was increased in chewing cane/peanut intercropping patterns partly,the production value and the profits were enhanced significantly.[Conclusions]CP_(2)could be significantly advantageous for the yield and benefits of chewing cane and peanut and soil *** favorable intercropping pattern for economic return would be one row of 120 cm width for chewing cane with two rows of peanut.
