Forage yield and quality in pearl millet-sesbania intercropping system under various geometrical patterns.

Intercropping of cereal and legume forages following proper planting geometry is an important strategy to achieve higher yield of quality forage. A field experiment was performed to evaluate agroqualitative response of forage pearl millet sown as a base crop and sesbania as intercrop under different geometrical patterns (line sowing of sole pearl millet, line sowing of sole sesbania, cross planting of pearl millet and sesbania, blended seed sowing of pearl millet and sesbania, sesbania intercropping in 30 cm apart rows of pearl millet, sesbania intercropping in 45 cm apart two-row strips of pearl millet, and sesbania intercropping in 75 cm apart four-row strips of pearl millet) at Agronomic Research Area, University of Agriculture, Faisalabad. Sesbania intercropping reduced pearl millet growth. Nonetheless, least decrease in height (23%), leaf area (42%) and number of leaves (16%) of pearl millet was occurred by intercropping sesbania in 45 cm apart two-row strips of pearl millet, as compared to sole cropping of pearl millet. Total green forage yield (60%) was increased by sesbania intercropping over sole-cropping of pearl millet and the intercropping of sesbania in 45 cm apart two-row strips of pearl millet was most beneficial. Intercropping improved quality of fodder mixture, compared to sole-cropping. Crude protein (84%) was improved most by cross planting over sole pearl millet, while, crude fiber (36%) and ash contents (20%) were improved by blended seed sowing, as compared to sole cropping of sesbania. Potential benefits of forage pearl millet can be acquired by intercropping with sesbania and following the planting geometry of sesbania intercropped in 45 cm apart two-row strips of pearl millet.
