Effect of soil type and depth of sowing on the seedling emergence, growth and yield performance of chinese long bean

Planting depth and soil type are important growth conditions which affect the performance of

different crops. This research was conducted to find out the effect of different planting depths (1 cm,

2 cm, 4 cm and 8 cm) under two different types of soil (loamy soil and sandy soil) on seedling

emergence, plant growth and yield performance of Chinese long bean (Vigna unguiculata). The

experiment was done following Randomized Complete Block Design with four replications per

treatment. Data were collected on seedling emergence, plant height, number of branches per plant,

number of leaves per plant, number of pods per plant, weight of pods per plant and seeds per pod.

Loamy soil clearly gave the best result in respect of seedling emergence, growth and yield of long

bean compared to sandy soil. Sowing depth affected mean seedling emergence, plant height,

branches produced, number of leaves per plant, number of pods produced, weight of pods and seeds

produced per pod. Sowing at 4 cm in loamy soil presented the best results in terms of long bean

yield. Sowing beyond 4 cm gave the relatively lower seedling emergence, growth and yield

performance of the Chinese long bean.
