TY - JOUR T1 - Yield and Competition Indices of Intercropping Cotton (Gossypium hirsutum L.) Using Different Planting Patterns* AU - Aasim, Muhammad PY - 2008 DA - January DO - 10.1501/Tarimbil_0000001048 JF - Journal of Agricultural Sciences JO - J Agr Sci-Tarim Bili PB - Ankara University WT - DergiPark SN - 1300-7580 VL - 14 IS - 04 LA - en AB - The study reports comparative bioeconomic efficiency of different cotton based intercropping systems using high yielding cotton cv. NIAB 78 of Pakistan in 80 cm spaced rows and 120/40 cm spaced rows with cowpea and sorghum as intercrops. Land equivalent ratio showed 32-46 % advantage over sole cropping in both planting patterns. Values of Area time equivalent ratio showed 5-13 % advantage in cotton+cowpea and 9-23 % disadvantage in cotton+sorghum intercropping. Agressivity and competitive ratio showed dominancy ofcotton over intercrops while intercrops were more dominant than cotton in actual yield loss values. Values ofAYL showed an advantage of 32.1 % to 116.3 % from intercropping due to recovery made by intercrops.Intercropping advantage values showed intercropping disadvantage (-3.865 to -151.035) from intercropping dueto price diffference of the component crop which meant that intercrops failed to compensate. Monetaryadvantage index values were also positive showing a definite yield advantage. Intercropping with cowpeareduced the yield of cotton, however, it seemed more appropriate for intercropping with cotton in both 80 cmand 120/40 cm spaced rows.. 120/40 cm spaced rows spacing seemed better compared to single row spacingfor easy handling of intercrops and sole cotton, therefore, it is recommended for mechanical farming inPakistan.
