“…The height of cayenne pepper plants at the first harvest was unaffected by pruning and chicken manure treatment (Table 3). The size of cayenne pepper plants, especially plant height, is dominantly controlled by genetics [28], so pruning and chicken manure treatments had little effect. The treatment of pruning branches below the dichotomous branching on cayenne pepper plants at the age of 3 WAP also had no impact on other parameters, such as fruit set, number of fruits per plant, and fruit weight plant and fruit weight per plot.…”

Improving the soil properties of a sandy dryland and carbohydrate allocation in crops grown on it is vital for crop production. This study explores the potential benefits of applying chicken manure and shoots pruning on fruit sets and the yield of cayenne pepper (Capsicum frutescens L.) grown on sandy dryland soil. An experiment testing a hybrid variety of cayenne pepper (Dewata 43) was conducted in Gumantar village, North Lombok, Indonesia (8.253654 S, 116.285695 E). Chicken manure treatment consisted of three levels; no chicken manure, chicken manure, and Trichoderma-enriched chicken manure at 3.5 ton ha−1. Pruning consisted of two levels; unpruned and pruned at three weeks after planting. The treatments were arranged factorially in a randomized block design with three replications. The study revealed that the soil was low in organic matter and had low nutrient content. Pruning did not show a significant effect, but chicken manure affected the fruit set and yield of cayenne pepper. Trichoderma-enriched chicken manure produced the highest fruit set (93%) and fruit weight per plant (286 g). The highest yield up to the fifth harvest was much lower than the variety’s yield potential, indicating room for improvement in cayenne pepper production in sandy dryland soils.

Being capable of accurately predicting morphological parameters of the plant weeks before achieving fruit maturation is of great importance in the production and selection of suitable ornamental pepper plants. The objective of this article is evaluating the feasibility and assessing the performance of CNN-based models using RGB images as input to forecast two morphological parameters: plant height and canopy diameter. To this end, four CNN-based models are proposed to predict these morphological parameters in four different scenarios: first, using as input a single image of the plant; second, using as input several images from different viewpoints of the plant acquired on the same date; third, using as input two images from two consecutive weeks; and fourth, using as input a set of images consisting of one image from each week up to the current date. The results show that it is possible to accurately predict both plant height and canopy diameter. The RMSE for a forecast performed 6 weeks in advance to the actual measurements was below 4.5 cm and 4.2 cm, respectively. When information from previous weeks is added to the model, better results can be achieved and as the prediction date gets closer to the assessment date the accuracy improves as well.
