Abstract
A field experiment was conducted on loamy sand soils of Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during the years 2011–12 and 2012–13. The soil of the experimental plot was very low in organic carbon (0.19%) and available nitrogen (169 kg/ha), medium in available phosphorus (39.65 ka/ha) and potash (271 kg/ha). The experiment was laid out in spit plot design with four replications. Fifteen treatment combinations comprised five intercropping treatments viz., IC1 (sole maize), IC2 (sole cowpea), IC3 (maize+cowpea 2: 1), IC4 (maize+cowpea 3: 1) and IC5 (maize+cowpea 3: 1) and three fertility levels viz., F1 (75% RDF), F2 (100% RDF) and F3 (125% RDF). Maize equivalent yield was significantly influenced by intercropping levels. Treatment IC4 (maize+cowpea 2: 1) recorded significantly higher maize equivalent yield than rest of the treatments. Application of treatments IC4 (maize+cowpea 2: 1) recorded significantly higher nitrogen content, crude protein content, crude fiber content and phosphorus content in both the crops. Intercropping levels failed to exhibit their significant influence on total ash content, potash content and neutral detergent fiber of both the crops. Regarding soil available nutrients, treatment IC2 (sole cowpea) registered maximum values of nitrogen content but phosphorus and potash content was not influenced significantly by intercropping after harvest of crops. The maize equivalent yield was significantly influenced by fertility levels. Application of F3 (125% RDF) produced significantly higher maize equivalent yield but it was statistically similar with treatment F2 (100% RDF). Application of 125% RDF recorded significantly higher nitrogen content and crude protein content and crude fiber content in both the crops as well as phosphorus content and total ash content in maize crop and it was at par with 100% RDF. Fertility levels failed to exhibit their significant influence on phosphorus content and total ash content in cowpea as well as potash content and neutral detergent fiber in both the crops. Regarding soil available nutrients, treatment F3 (125% RDF) registered maximum values of nitrogen but it was at par with F2 (100% RDF). Application of intercropping IC4 (maize+cowpea 2: 1) recorded higher net realization of Rs. 30185/ha and higher BCR value of 2.85. Among different fertility levels, application of 125% RDF resulted in higher net realization (Rs. 28865/ha) but higher BCR (2.68) was recorded with treatment F2 (100% RDF) with net realization (Rs. 28411/ha) closely followed by F3 (125% RDF). The land equivalent ratio (1.22) was highest with IC4 (maize+cowpea 2: 1).
