“…Nitrogen is also very important in relation to the formation of chlorophyll in plant leaves (Arena et al 2020). Nitrogen element functions to increase plant growth, indicated by nourishing leaf growth with greener leaf colors (Putri et al 2021). Plants that have a high chlorophyll content are expected to be efficient in utilizing solar energy to carry out the photosynthesis process (Janeeshma et al 2022), and will also increase plant biomass and crop seed yields (Putri et al 2021).…”

Abstract. Sudharta KA, Hakim AL, Fadhilah MA, Fadzil MN, Prayogo C, Kusuma Z, Suprayogo D. 2022. Soil organic matter and nitrogen in varying management types of coffee-pine agroforestry systems and their effect on coffee bean yield. Biodiversitas 23: 5884-5891. Coffee cultivation in agroforestry systems is mostly planted without soil fertility management. While there are several management interventions to improve soil quality in agricultural practices, it is not clear whether particular treatments, such as adding organic fertilizers and nitrogen fertilizers could increase coffee production in agroforestry settings. This study aimed to analyze soil organic matter and nitrogen in varying management types and its effect on coffee bean yield in a coffee-pine agroforestry setting in East Java, Indonesia. We evaluated four types of coffee management (treatments) namely: (i) no management, (ii) pruning coffee plant branches, (iii) a combination of pruning and addition of fertilizers with a planting distance of pine trees of 3 x 2 m, and (iv) pruning under pine trees with a planting distance of 6 x 2 m. The soil organic matter, total and available soil nitrogen were measured at 0-0.2 m and 0.2-0.4 m soil depths. We measured coffee bean yield to 100 coffee plants per plot. The coffee bean yield in the no-management treatment reached 376 kg ha-1, while the yield under the other three treatments increased up to 3.9 times compared with no-management. This increasing coffee bean yield did not correlate with soil organic matter in topsoil, with a correlation between coffee bean yield and total ant available soil nitrogen being positive and negative, respectively. We concluded that the limitation of N in the coffee-pine agroforestry system would require management intervention in the form of adding nitrogen fertilizers to increase coffee bean yield.

“…Chinese hardneck had the lowest chlorophyll a and b in all photoperiod treatments. Different genotypes have differed in genetic makeup, leading to varied chlorophyll pigment content in their growth and development (Putri et al 2021). The difference in total chlorophyll content can be related to whether the plant growth is in an active vegetative state, juvenile, or entering the adult phase in each genotype.…”

Abstract. Kendarini N, Aisyah SI, Maharijaya A, Sobir. 2022. Photoperiod effect on vegetative growth and bulbing initiation of four garlic genotypes. Biodiversitas 23: 4716-4723. The main factors influencing garlic growth and development were genetics, photoperiod, and temperature. Low temperature and short photoperiod were required for initial growth, followed by a long photoperiod and high temperature for bulbing and bolting. The study was conducted to evaluate the response of garlic genotypes to photoperiod on the vegetative growth and bulbing initiation, and physiological traits (C/N ratio, GA, and total chlorophyll content). Four garlic genotypes used in this experiment consisted of two Chinese garlic genotypes (hardneck and softneck) and two local garlic cultivars (Sangga Sembalun and Tawangmangu Baru). The garlic plants were subjected to the treatment of short photoperiod (control) and long photoperiod (night break and extension methods). The results showed that the Chinese hardneck and softneck had plant vegetative growth with a higher vigor than Sangga Sembalun and Tawangmangu Baru in all photoperiod treatments. Sangga Sembalun and Tawangmangu Baru had bulbing index below 0.3 in all photoperiods. The Chinese hardneck and softneck genotypes had bulbing index greater than 0.5 in all photoperiod treatments, except the hardneck in the night break treatment. The bulbing initiation in Chinese garlic genotypes was delayed in long photoperiod treatments. High temperature during the experiment affected bulbing initiation in long photoperiod treatment. The garlic genotypes had different responses to photoperiod treatments in C/N ratio, GA, and total chlorophyll content. The vegetative growth increased under extension treatment, and night break accelerated bulb formation. Long photoperiod increased C content and C/N ratio in the leaves while it decreased N content and photosynthetic pigment content. The late maturity time (Chinese hardneck and Chinese softneck) depended on long photoperiods for the bulbing formation. In contrast, local garlic cultivars with the early and mid-season types (Sangga Sembalun and Tawangmangu Baru) were insensitive to photoperiod.

“…Shallot plant is mostly cultivated for its bulbs, while the leaves are not commonly consumed, unlike shallot whose leaves are consumed, which are called green shallots or scallions [7]. From the results of research by Alimudin et al 2017 [8], showed that the use of shallot extract at a concentration of 70% was the best treatment compared to the concentration of the parameters of root length, number of roots, fresh weight of roots and dry weight of root cuttings of rose (Rosa sp.)…”

Fig is shrub with short stems, creeping, not many trunks and woody which have cambium tissue due to thickening between the xylem and phloem, can grow and bear fruit in the hot sun or in the desert. Fig plant is a plant that has many benefits. The purpose of this research is to determine the effect of natural Plant Growth Regulator (PGR) (mature coconut water, young coconut water and shallot extract) and obtain the best concentration of PGR for Fig plant cuttings. The study was carried out by field trial methods arranged in Completely Randomized Design (CRD) with a single factor trial design. The treatments tested were the addition of PGR from natural ingredients, namely: mature coconut water 20% and 30%, young coconut water 20% and 30%, red shallot extract 60% and 70% and commercial PGR (Root-Up™™). Each treatment was repeated 3 times. The results of this search showed that all-natural PGR tested, namely from young coconut water concentrations of 20% and 30%, mature coconut concentrations of 20% and 30% and shallots concentrations of 60% and 70% can be used to increase the growth of Fig plant cuttings. All natural PGRs tested, namely young coconut water with a concentration of 20% and 30%, mature coconut with a concentration of 20% and 30% and shallots with a concentration of 60% and 70% can be used to increase the growth of fig plant cuttings.
