Abstract

Sugarcane (Saccharum officinarum) can grow well in soil and environmental conditions that are under growing requirements and accompanied by good management also. The land is a natural resource with a permanent nature, while the human need for land continues to increase and the high need for nutrients in sugarcane causes a rapid decline in nutrients in the soil, especially monoculture sugarcane. This study aims to determine the effect of the response of sugarcane growth on the depth of juringan and the dosage of P fertilizer. The experiment was carried out at Wedomartani Experimental Garden, Ngemplak, Sleman, Yogyakarta from January to March (3 months). The experiment used a factorial randomized block design. The first factor is the depth of the rod with three treatments, namely: the depth of the rod 15 cm (K0), the depth of the rod 30 cm (K1), and the depth of the rod 45 cm (K2). The second factor was the dosage of P fertilizer with three treatments, namely: without P fertilizer (P0), P fertilizer 13 g / seed (P1), and P fertilizer 22 g / seed (P2). Six treatment combinations were repeated three times so that there were 27 experimental units. Each experimental unit consisted of two plants, so there were a total of 54 plants. The results showed that there was no interaction between the different depths of the net and the dosing of P fertilizer on all observed variables. Application of different P fertilizers had a single effect on plant height, number of tillers, and leaves. Application of P fertilizer (22 g / seed) resulted in higher plant height and number of tillers compared to without P fertilizer. Keywords: monoculture, phosphorus, sugarcane, production.

Abstract

Sustainable intensification of oil palm plantations faces the challenge of decreasing soil fertility and increasing the price of inorganic fertilizers. Organic matter plays an important role in maintaining soil fertility. Empty fruit bunches (EFB) are the main co-product of palm oil mills that have the potential to be used as a source of organic matter and nutrient sources. This study aims to reveal the effect of the application of empty fruit bunches in increasing the effectiveness and substituting inorganic fertilizers for the components of oil palm production. The number of female inflorescence, the number of FFB and the average weight of FFB were observed for 3 years on palm aged 8, 9 and 10 years. Application of EFB + 70% recommended inorganic fertilizer. The recommended fertilizer is 8 kg per tree (N P K Mg 14-28-6-2 +0.5 B). EFB are applied as one layer of mulch with a size of 3x4 m on a dead net. The results showed that the application of empty bunches could increase the number of female flowers and the number of FFB in plants aged 9 and 10 years (1-2 years after application), while inorganic fertilizer EFB was only at the age of 8 years (0 years after application) for both production components. FFB weight one year after application of EFB+70% inorganic fertilizer (age 9 years ) was higher than 8 and 10 year aged plants. The application of EFB+70% inorganic fertilizer can increase the contribution of nutrients from fertilizers compared to the application of inorganic fertilizers solely.

Abstract

Shallots are one of the leading horticultural commodities that have been cultivated by farmers for a long time. Constraints in the cultivation of shallots in Indonesia are environmental conditions such as soil types. This study aims to determine the effect of the type of planting medium and the application of NPK fertilizer on the growth and yield of shallot (Allium ascalonicum L.). This research is conducted at Caping Merapi which is located at Jl. Raya Tajem KM 2.5, Wedomartani, Ngemplak, Sleman, D.I.Yogyakarta from November 2021 to January 2022. The research design used was a split-plot design using 2 factors: the dose of NPK fertilizer and the composition of the growing media. The main plot is NPK fertilizer and the sub-plot is the type of planting media. The data obtained are analyzed using variance (Anova). The results of the variance showed a significant effect, then continued with the Duncan test (DMRT) with a 5% level. The results show that there is no interaction between the treatment of the type of planting media and the dose of NPK fertilizer on the growth and yield of shallots. The effect of giving the type of peat soil planting media was better on plant height and number of leaves. The application of 15 grams/plant was better for the number of leaves, number of tillers, fresh weight of leaves, fresh weight of tubers, and number of tubers.

Abstract

This study aims to determine the plant growth parameters that most influence sugarcane productivity. The research was carried out from April 2021 to September 2021 in Argomulyo Village, Cangkringan District, Sleman Regency, Yogyakarta. This research was conducted using a survey method by taking samples of sugarcane stalks at each sampling point. The land area is 3 ha which is divided into 3 blocks, then from each block 10 sugarcane samples are taken so that there are 30 sugarcane samples. Parameters observed in this study were plant height, number of stems, stem diameter, number of leaves, number of internodes, and weight of sugarcane stalks. The results showed that the parameters that had a very high effect on productivity were stem diameter (r=0.986), number of tillers per clump (r=0.908) and sugarcane plant height (r=0.904). Meanwhile, the correlation with sugarcane stalk weight was high (r=0.879), with the number of leaves and cane stem segments very low (r=0.160 and r=0.172). Land productivity in the research location was also much lower than its potential. The addition of organic matter to improve the physical properties of the soil and increase the availability of nutrients was needed so as to increase the growth and productivity of sugarcane.
