Abstract

One obstacle that can limit the growth and production of rice is low water availability. Therefore, a comprehensive study of the response of rice plants to drought is very important. The study was conducted in the greenhouse of the Faculty of Animal Husbandry and Agriculture, Diponegoro University, from April to August 2016. The study used a 3 x 3 factorial design with 3 replications. The first factor is three types of rice (Sidenuk, Way Apo Buru, Pepe) and the second factor is water stress treatment (KA <field capacity = enough water, field capacity (KL), water saturation (JA). The observed parameters are protein content, leaf levels rolling (number of leaves rolled), relative water content (RWC), water use efficiency (WUE),  N, P, K uptake, rice protein content decreases with increasing water supply. The relative water content of rice plants decreases with increasing stress water that occurs in the limited water supply for the three types of rice Sidenuk rice has the lowest N seed content (2.1%) compared to Way Apo (3.0%) and Pepe (3.1%). The mineral content of P in both biomass and seeds is not really influenced by water stress, as well as K content of seeds.   REFERENCES Badan Pusat Statistik. 2018. https://www.bps.go.id/dynamictable/2019/04/15/1608/luas-panen-produksi-dan-produktivitas-padi-menurut-provinsi-2018.html Darwesh, R, S,S. 2013.

Abstract

This research aimed to assess the effect of several types of growing media and AB Mix substitution with organic nutrition on Kailan (Brassica oleraceae L.) growth. The study used a factorial 3 x 4 completely randomized design (CRD) with 3 replications. The first factor is the treatment of growing media which consists of Rockwool, Charcoal husk, and Cocopeat. The second is the AB Mix Substitution with organic nutrition consisting of AB Mix substitution with 0% organic nutrition, AB Mix Substitution with 25% organic nutrition, AB Mix Substitution with 50% organic nutrition, and AB Mix Substitution with 100% organic nutrition. Growth parameters observed included plant height, number of leaves, root length, canopy wet weight, root wet weight, canopy dry weight, root dry weight, and chlorophyll. Data were analyzed using ANOVA and continued by DMRT (Duncan's Multiple Range Test) at 5% level. The results showed that the planting media treatment increased growth in the plant height, number of leaves, root length, canopy wet weight, root wet weight, and canopy dry weight. The treatment of AB Mix substitution with 25% organic nutrition is equivalent to the treatment with 0% organic nutrition for all parameters except chlorophyll. The AB Mix substitution treatment with 50% organic nutrition is not equivalent to the treatment without substitution. The higher substitution treatment will affect growth.

Abstract

Banana plants are annual horticultural crops that have production capability without depending on the season and are widely cultivated in the tropic or subtropic areas. Tissue culture can produce good-quality banana seedlings in large quantities. To stimulate their metabolic systems, Banana plantlets from tissue culture require appropriate growing media and growth regulators such as auxin. The research aims to examine the effect of IAA auxin hormone concentration, the composition of sand: compost: husk charcoal and its interactions on the growth of raja bulu banana plantlets. The research was conducted in July - September 2019 at the Plant Physiology and Breeding Laboratory, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang. The study used a complete randomized factorial design 4x2 with 5 replications. The first factor was IAA concentration (K) consists of 4 levels, K0: 0 ppm, K1: 30 ppm, K2: 60 ppm, and K3: 90 ppm. The second factor was the composition of growing media (M), M0: sand: compost: husk charcoal (1: 1: 1) and M1: sand: compost: husk charcoal (1: 1: 2). Data were analyzed by F test and proceeded by DMRT test at the level of 5%. The results showed that IAA significantly affected stem diameter, number of leaves, chlorophyll content and nitrate reductase activity of banana seedlings. The treatment of growing media significantly affected plant height and number of leaves. Concentration of 30 ppm IAA at all growing media increased significantly on stem diameter, number of leaves, chlorophyll content and nitrate reductase activity.
