Growth and Dry Matter Accumulation of Okra (<i>Abelmoschus esculentus</i> L.) as Influenced by Different Plating Pattern Under Okra - Cowpea (<i>Vigna unguiculata</i> L.) Intercropping

Abstract

Compared to sole cropping, intercropping systems can more efficiently use the existing resources which ultimately lead to improved plant growth and dry matter accumulation. So, most of the farmers in developing countries can follow the intercropping systems with high yielding crop combinations. The experiment was carried out at the Crop Farm of Eastern University, Sri Lanka in 2018 to investigate the growth and dry matter accumulation in okra (Abelmoschus esculentus L.) as influenced by different planting patterns under okra-cowpea (Vigna unguiculata L. Walp) intercropping in sandy regosol. The experiment was laid out in a Randomized Complete Block Design (RCBD). Treatments were okra as a sole crop (T1), cowpea as a sole crop (T2), alternative planting of okra and cowpea (T3), 60/150 cm paired row planting of okra with two rows and three rows of cowpea in between paired rows (T4 and T5) and 75/120 cm paired row planting of okra with two rows and three rows of cowpea in between paired rows (T6 and T7). Plant height, root length, fresh and dry weights of plant, leaf area, leaf area index, canopy width and cumulative yield of okra were higher in T5, while chlorophyll content showed no significant difference (P&gt;0.05) with different planting patterns. The present study concluded that 60/150 cm paired row planting of okra with three rows of cowpea in between paired rows (T5) would be the most suitable planting system in sandy regosol to achieve better growth and dry matter in okra.

Physiological and Morphological Responses of Okra (Abelmoschus esculentus L.) to Rhizoglomus irregulare Inoculation under Ample Water and Drought Stress Conditions Are Cultivar Dependent

“…In general, the values of specific root length (SRL) in cm/g root DW and the root length density (RLD) in cm/cm 3 were remarkably high especially in +M plants as compared to values published for okra plants. The root diameter was comparable to that found in published studies [ 33 , 34 , 35 , 36 , 37 ].…”

“…We speculate that plant species with a high MD, such as okra, may show root morphological responses to AMF colonization different from that of plant species with lower MD, such as most grasses or tomatoes. The higher values of SRL and RLD in our study compared to previously published values [ 33 , 34 , 35 ] could be attributed to the age of the plant at the time of RLD measurement. We measured the root parameters 3 months after cultivation while the other studies measured the parameters 1–2 months after cultivation.…”

"Influence of Intercropping Combinations on Growth, Components, Yield, and Quality of Faba Bean and Potato"

“…The shortest plant heigh recorded by intercropping than sole cropping might be associated with high competition of minerals and nutrients by intercrops than the sole cropped plants. In contrast to this result, different research verified that the vegetative growth mainly plant height and leaf area index are enhanced by intercropping than sole cropping systems [24,25].…”

Dissipation Kinetics, Residue Modeling and Human Intake of Endosulfan Applied to Okra (Abelmoschus Esculentus)

“…From Table S5, we can see that comparison of nominal values of some important cropspecific model input parameters (most importantly, LAI t0 , LAI app , and LAI harv ) showed reasonable similarity for the studied (okra) and other crops (e.g. tomato), based on Fantke et al (2011Fantke et al ( a, b, 2014; Maduwanthi and Karunarathna (2019) and Salau and Makinde (2016). Hence, such data were applied as model input where okra-specific data were lacking or insufficient.…”
