Abstract

Changes in rainfall with high humidity due to La Nina can be one of the factors that can affect the quality of the yield of horticultural products. La Nina simulation was done by soaking snake fruits in water for a certain time. The aimed of this research was to examine the effect of La Nina carried out using simulations on several quality parameters of snake fruits. This research used a non-factorial Completely Randomized Design (CRD) with two treatments, fruit without soaking and fruit soaked for 5 minutes (La Nina simulation). The treatment was repeated three times. Observations were made at 0 days, 3 days, 6 days and 9 days. The La Nina simulation treatment with 5 minutes soaking affected the quality of snake fruits, which shown by the decreasing in the physical appearance of the fruit, the hardness of the fruit, and the total acid content of the fruit. In general, a decrease in some qualities of snake fruits occurs on the 6th to 9th day of storage.

Abstract

Drought is abiotic stress that can inhibit the growth and yield of rice plants. A simple method to determine the physiological response, growth, and yield of rice is using plant growth analysis. The aim of this research was to study the physiological characters of IPB 4S rice varieties on planting media with different drought stress levels using plant growth analysis. This research used a non-factorial completely randomized design with 6 levels of water percentage from field capacity, namely field capacity, 10% of field capacity, 20%, 30%, 40%, and 50% of field capacity. The treatment was repeated three times so that there were 18 experimental units. Observation of plant growth analysis was carried out by measuring leaf area and plant dry weight at 3 and 8 days after planting. Drought stress 20-50% of field capacity has a net assimilation rate, leaf area index, and plant growth rate 8 weeks after planting lower than drought stress at field capacity up to 10% of field capacity. In general, an increase in drought stress by 20-50% results in a decrease in net assimilation rate, plant growth rate, and leaf area index of 8 weeks after planting. This shows that the IPB 4S variety of rice plants has tolerance to drought stress up to 10% of the field capacity.

Abstract

Consumer demand for mustard needs in Indonesia is increasing. Efforts to produce mustard greens use an aeroponic system to utilize nutrients in dosage and type correctly. The study aimed to determine the proper type of nutrition for the growth and production of two mustard greens in an aeroponic system. This study used a completely randomized design with two factors. The first factor is the type of mustard which consists of two levels, namely pakcoy and pagoda. The second factor to consider is the nutrition applied at three different levels: AB mix, liquid organic fertilizer, and foliar fertilizer. Mustard greens grew and produced significantly differently when grown in an aeroponics system. Other nutrients greatly affected all observed variables, including plant height, leaf number, leaf color, root length, fresh plant weight, and dry plant weight. The use of pakcoy mustard provides the best growth and production of mustard greens compared to pagoda-type mustard. Giving AB mix nutrition to mustard greens can provide the best growth and production compared to nutrition from liquid organic fertilizers and foliar fertilizers. The AB mix nutritional treatment with pakcoy mustard produced the best results in plant height, leaf number, wet weight, dry weight, and root length. AB mix nutritional showing the best leaf color variable with pagoda mustard greens.
