Abstract:
Two field experiments were conducted during 2010/2011 and 2011/2012 seasons in sandy soil under drip irrigation system at the Regional Agricultural Research Station, New Valley, El-Kharga Governorate, Egypt. The objectives of this study were to determine: (1) Whether the yield and its components of tomato are reduced when they are interplant with different plant population density of common bean. (2) The appropriate planting ratio that would give high yields of tomato and common bean and (3) Ascertain monetary returns from tomato/common bean intercrops. The efficiency of diffirent cropping systems can be evaluated by land equivalent ratio which was determined as an index of intercropping advantage and economic net income. Tomato (Lycopersicon esculentum Mill cv. Super Strain B) as a main cop was intercropped with different plant population density of common bean (Phaseolus vulgaris L. cv. Bronco) as intercrop. All crops were grown also in pure stands. Treatments consisted of combinations of three densities of common bean for each tomato plant (1 tomato plant: 1 or 2 or 3 common bean plants) in a randomized complete block design. Results of this study showed that yield response of tomato due to different intercropping systems was insignificant. Also, results showed that different intercropping system compared to sole did not affected yield and some component of tomato. This indicated also that tomato plant can be tolerating common bean plants without adverse effect on yield. Common bean yield of intercropping systems increased as number of plants associated with tomato increased. Data showed a high additional increase in profits over the each cost for one plant tomato: three common bean plants. The highest LER (Land Equivalent Ratios) was found 1 tomato plant: 3 common bean plants as 1.26 and 1.25 in 1st and 2nd seasons, respectively. It is recommended to use this pattern to improve farmer's income and LER under New Valley conditions.
