Growth and Vegetable Pod Yield of Edible Podded Pea as Influenced by Sowing Time and Plant Density

Abstract: An experiment was carried out to study the growth and vegetable pod yield of edible podded pea as influenced by sowing time and spacing. The experiment consisted of two factors, which were three sowing times and six plant spacings. The results revealed that Nov. 23 sown plants showed higher leaf area index, leaf, stem and pod dry matter, plant height and vegetable pod yield than those of Nov. 8 and Dec. 8 sowing. Closest spacing produced the highest LAI, leaf, stem and pod dry matter, crop growth rate, plant height and vegetable pod yield. However, relative growth rate and net assimilation rate were the highest in widest spacing. Regardless of variation in sowing time and spacing, LAI, leaf and stem dry matter, CGR, RGR and NAR increased sharply up to 60 DAE and then declined but pod dry matter increased thereafter. Moreover, plant height increased rapidly up to 60 DAE and then slowly. The highest vegetable pod yield (10.26 t ha -1) was recorded from the Nov. 23 sowing with 30x20 cm2 spacing.
