Abstract

This study aims to determine the response of KNO3 and Agrodyke fertilizer to the yield of siam oranges and their interactions. This research is a field experiment conducted in Banjar Belancan, Belancan Village, Kintamani Subdistrict, Bangli Regency starting from January to July 2018. This study uses a Randomized Block Design (RBD) with 2 factors arranged factorially. the first factor was tried was KNO3 which consisted of 3 levels namely K0 (0 g/plant), K1 (20 g/plant) and K2 (40 g/plant, while the second factor that was tried was Agrodyke (A) fertilizer consisting of 4 levels namely A0 (0 g/plant), A1 (15 g/plant), A2 (30 g/plant) and A3 (45 g/plant), thus there are 12 combination treatments, each repeated 3 times so that 36 trees are needed Siamese plants interaction between KNO3 treatment with Agrodyke fertilizer treatment (KxA) had no significant effect (P≥0.05) on all observed variables KNO3 treatment The highest fruit weight per tree was obtained in KNO3 treatment with a dose of 40 g / plant (K2) ie 12.70 kg increased by 50.29% when compared to the lowest yield in the treatment without KNO3, which was only 8.45 kg, the highest yield of fruit per tree was obtained in Agrodyke treatment with a dose of 30 g/plant (A2), namely 12.90 kg has increased 61.47% when compared to h the lowest acyl in treatment without Agrodyke is 7.89 kg.

Abstract

This study aims to determine the level of fruit maturity to get the quality of citrus fruits during storage. This experiment is a factorial experiment with the basic design of a simple randomized block design (RBD) one factor consisting of four levels of fruit maturity, namely: TK_1 (Physical appearance of Green fruit peels), TK_2 (Physical Display of Yellowish Green rind), TK_3 (Physical Display Yellow green rind), TK_4 (Physical Display of Evenly rind rind), each of which is repeated six times. This research was conducted in the first two places, namely in the siam plantation owned by one of the farmers in Banjar Seming, Kerta Village, Payangan District, Gianyar Regency. The second place is the Warmadewa University Faculty of Agriculture Laboratory, which runs from March to May 2017. Fruit quality seen from physical properties during storage (8th day) there was a decrease in fruit weight which was higher in physical appearance of evenly yellow rind which was 19.19 g compared to the physical appearance of yellowish green rind which was 17.26 g. Decrease in fruit diameter is also highest obtained in the physical appearance of 100% yellow rind that is 0.56 cm compared to the physical appearance of yellowish green rind that is 0.45 cm. Fruit quality seen from the chemical properties during storage (8th day) there was a decrease in vitamin C content at all levels of fruit maturity, while the total dissolved solids increased at all levels of fruit maturity. The highest total dissolved solids were obtained on the physical appearance of evenly yellow rind that was 9.42 oBrix compared to the physical appearance of greenish yellow rind, the physical appearance of yellowish green rind and the physical appearance of rind of rind, respectively 9.38 oBrix, 8 , 63 oBrix, and 8,32 oBrix. The longer the fruit is stored the more sweet the fruit is but the fruit is increasingly constricted and unfit for consumption

Abstract

The purpose of this study was to determine the effect of doses of potassium nitrate and magnesium sulfate on the production of Siamese orange (Citrus Nobilis Var. Microcarpa L.) and their interactions, which was carried out in Bayung Gede Village, Kintamani District, Bangli Regency from December 2021 to July 2022. This study used a Randomized Block Design (RAK) with 2 factors arranged in a factorial manner. The first factor that was tried was the dose of potassium nitrate (K) fertilizer which consisted of 4 levels, namely: K0 (0 g/tree), K1 (250 g/tree), K2 (500 g/tree) and K3 (750 g/tree). . . While the second factor was the dose of magnesium sulfate (M) fertilizer which consisted of 4 levels, namely: M0 (0 g/tree), M1 (5 g/tree), M2 (10 g/tree) and M3 (15 g/tree). Thus, there were 16 treatment combinations, each given 3 times, so 48 citrus trees were needed. The results showed that the interaction of potassium nitrate fertilizer dose with magnesium sulfate (KxM) fertilizer did not significantly affect all observed variables. The highest fruit weight per tree was obtained at a dose of potassium nitrate fertilizer of 750 g/tree, which was 11.53 kg, an increase of 96.75% when compared to without potassium nitrate fertilizer which was only 5.86 kg. While the magnesium sulfate fertilizer treatment obtained the highest harvested fruit weight per tree at a dose of 15 g/tree, namely 10.17 kg, an increase of 30.05% when compared to magnesium sulfate fertilizer which was only 7.82 kg.
