Sole Cropping

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>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.

Six concentrations each of KNap and NAA along with a control were tested on cowpea cv. Bari Falon- 2. Results showed that irrespective of treatment differences, dry matter of cowpea (Vigna unguiculata) increased during 60 to 105 DAS. Concentrations above 50 ppm NAA increased plant height. The dry matter and yield increased with the increasing of the concentrations of KNap and NAA up to 1250 and 50 ppm, respectively. No significant differences of dry matter accumulation, grain yield and almost all the yield attributes were observed in between 1250 ppm KNap and 50 ppm NAA. The highest values of dry matter/plant (54.52 g), pod length (13.15 cm), number of pods/plant (10.29), number of seeds/pod (10.61), 1000 seed weight (122 g), seed yield/plant (15.51 g), seed yield/ha (1630 kg) and harvest index (37.32 %) were obtained due to application of 1250 ppm KNap. Yield attributes had significantly positive correlation amongst them.   Key words: Cowpea, Vigna unguiculata, Plant height, Dry matter, Yield DOI = 10.3329/bjb.v36i2.1500 Bangladesh J.

Field experiment was conducted to determine the effect of swine manure application on the growth components and chemical composition of nine varieties of improved dual-purpose cowpea (Vigna unguiculata L. Walp). The experiment was laid out as a 2 x 9 factorial design with two levels of manure application (0kg ha-1 and 5kg ha-1) and nine varieties of improved dual-purpose cowpea at three replicates. Agronomy parameters and dry matter yield of the cowpea were determined six weeks after sowing. Results showed that unfertilized variety IT- 332 recorded highest leaf proportion (57.27) above others. Varieties IT-193 with manure (80.00 cm) and IT-297 without manure (30) recorded significantly higher (P<0.05) values for plant height and leaf number respectively. Dry matter yield of cowpea ranged significantly higher (P<0.05) from 7.20 t ha-1 in variety IT-817 without manure to 14.85 t ha-1 in variety IT-321 with manure. The average crude protein content of improved cowpea varieties ranged significantly (P < 0.05) from 97.69 g kg-1 dry matter in unfertilized IT-817 and IT-834 to 141.17 g kg-1 dry matter in fertilized IT-819. The study showed that application of swine manure into cowpea increased the dry matter yield and chemical composition which is necessary to provide sufficient feed for ruminants that can be used as a supplement during the dry season.

The maturation process of seeds is genetically controlled and involves an organized sequence of physiological changes from the fertilization until the complete independence from the plant. It is recommended that the harvest occurs in the ideal moment, this way the seeds can express their full potential, with maximum dry matter accumulation, reaching high potential of germination and vigor. The objective of this study was to determine the physiological maturity point of cowpea bean seeds (Vigna unguiculata L. Walp.), cv. Corujinha, aiming to indicate the best harvesting period, in order to guarantee greater germination potential and seed vigor. Cowpea pods were harvest from the third until the twenty-first day after anthesis, with intervals of three days between the harvests. After each harvest, the following evaluations were carried out: pod and seed color, number of seeds per pod, pod and seed biometry, pod and seed moisture, water content, germination, germination speed index, length and dry matter of the shoots and roots. At 15 DAA, the seeds and pods presented light green coloration, with maximum values of length, width, thickness, dry matter, germination percentage and germination speed index, at a vigor level. There was a gradual reduction of water content in the seeds and number of seeds up to 21 DAA. The highest values for shoot and root length were observed at 18 DAA, when seeds and pods showed light brown color and for shoot and root dry matter at 21 DAA, with brown color. The physiological maturity of cowpea seeds was rapid and occurred between 15 and 21 DAA. The harvest is recommended at 15 days after anthesis, when the seeds present high physiological quality.
