Abstract

The purpose of this research is to determine the effect of compost and NPK Phonska fertilizer application to the growth and yield of okra plants, and to get optimum dose. This research was conducted in experimental garden of Agricultural Faculty of Warmadewa University. The design used in this research is factorial randomized block design (RAK) consisting of two treatments: compost fertilizer and NPK Phonska fertilizer. The interaction treatment between doses of compost fertilizer with NPK Phosnka and single treatment of NPK Phonska have no significant effect on all observed variables. The treatment of compost fertilizer dosage have no significant to effect foe leaf number and dry weight of oven fruit, but it had significant effect to the weight of fresh and dried weight of oven stover and very significant effect on the variables of plant height, the number of fruit and the weight of fresh fruit. The dosage of compost fertilizer 8 ton ha-1 to got the highest fresh weight of fruit per plant which is 380,42 g, an increase of 44,05% if compared with the lowest fresh fruit weight per plant obtained in the treatment without compost 0 tons ha- Ë¡ of 264.08 g. The results of the distribution of NPK Phonska at different doses have no significant effect on one another . However, , the highest fresh fruit weight was obtained at NPK treatment at 400 kg ha-1 treatment ie 351,75g. This increased by 7.02% when compared with the freshest weight of lowest fruit obtained at 200 kg ha-1 treatment ie 328,67 g.

Abstract

This study aims to determine the effect of bamboo biochar dose on the growth and yield of peanut crops. This study used a randomized block design with one factor. The tested treatments were dosage of biochar fertilizer with 4 dosage levels and one treatment without biochar dose (control), with the treatment arrangement as follows: without biochar, 4 ton ha-1, 8 ton ha-1, 12 ton ha-1, 16 ton ha-1. This treatment was repeated 3 times to obtain 15 plot experiments. The results showed that the biochar dose treatment had significant effect on all observed variables, except the variable of plant height and maximum number of leaves per plant had no significant effect. The highest yield of dry seed oven of seeds per plant was obtained in the dosage of 4 ton ha-1 biochar dose of 21.83 g, an increase of 111.81% compared with no biochar 10.33 g. Based on regression analysis, the optimum dosage of biochar is 7.50 ton ha-1, with dry weight of oven seed per plant maximum 19.03 g.

Abstract

This study aims to determine the effects of mycorrhizal and indole butyric acid (IBA) growth regulators and their interactions on siam citrus products. This study uses a randomized block design (RBD) with two factors arranged factorially. The first factor to be tried was the mycorrhizal dose which consisted of 3 levels, namely 0, 50, and 100 g/plant, while the second factor tried was the concentration of the substance indole butiric acid (IBA) growth regulator consisting of 4 levels, namely 0, 50, 100, and 150 ppm/plant. Thus there are 12 combination treatments, each of which is repeated 3 times so that 36 citrus trees are needed. The results showed that the interaction between mycorrhizal dose and the concentration of IBA had no significant effect on all observed variables. Treatment of mycorrhizal doses and dosage of IBA had a very significant effect on the weight of harvested fruit per tree. The highest yield of fruit per tree was obtained in 100 g / plant mycorrhiza treatment, which was 13.53 kg, an increase of 57.88% compared to the lowest yield in mycorrhiza treatment, which was 8.57 kg. The highest yield of fruit per tree was obtained at IBA concentration of 100 ppm / plant, which was 15.03 kg, an increase of 78.08% compared to the lowest yield on IBA concentration without 8.44 kg.

Abstract

The purpose of this study was to determine the effect of various types of mulch and NPK pearl fertilizer on the growth and yield of shallots (Allium ascalonicum, L.). This research is a factorial experiment with a basic design randomized block design (RBD) consisting of 2 factors, namely the first factor is the type of mulch (M) which consists of 3 levels of treatment, namely straw mulch (MJ), silver black plastic mulch (MP), and husk mulch (MS). While the second factor is NPK pearl (P) fertilizer which consists of 4 levels of treatment, namely 0 kg/ha (P0), 100 kg/ha (P1), 200 kg/ha (P2), and 300 kg/ha (P3). This research was conducted in paddy fields located in Sanding Village, Tampaksiring District, Gianyar Regency with an altitude of ± 750 masl and this research activity was carried out from February 26 to April 26 2020. The results showed that husk mulch gave a higher fresh weight of tubers per clump, namely 69.60 g, which was not significantly different from straw mulch and silver black plastic mulch, namely 61.07 g and 56.26 g. The highest fresh weight of tubers per clump and per hectare was obtained at the NPK pearl fertilizer dosage of 300 kg/ha, namely 73.61 g and 184.03 Ku, an increase of 63.94% and 63.96% compared to the NPK pearl fertilizer dosage of 0 kg/ha namely 44.90 g and 112.24 Ku.

Abstract

This study aims to determine the effect of giving MKP fertilizer, rabbit solid organic fertilizer and the interaction of MKP fertilizer with rabbit solid organic fertilizer on the growth and yield of cayenne pepper plants. This research was conducted in Subak Rapuan, Mas Village, Ubud District, Gianyar Regency with an altitude of 400 meters above sea level. The experiment lasted for 4 months, from May to July 2022. This experiment used a Randomized Block Design (RAK) with 2 factors arranged in a factorial manner. The first factor is using MKP fertilizer with 4 levels, namely M0: 0 g l-1 water, M1: 2 g l-1 water, M2: 4 g l-1 water, M3: 6 g l-1 water and the second factor is using solid organic rabbit fertilizer consisting of 3 levels, namely P1: 10 tons ha-1, P2: 20 tons ha-1 and P3: 30 tons ha-1. Observations of plant height, number of leaves, number of flowers, and number of fruit will begin 3 weeks after planting, while the fresh weight and dry weight of fruit and stover will be measured at the end of harvest. The results of statistical analysis showed that the application of MKP fertilizer to cayenne pepper plants had a very significant effect on the variables of maximum leaf number, number, number of flowers, total fruit number and fruit fresh weight and had no significant effect on maximum plant height, fruit oven dry weight, fresh weight of stover and oven dry weight of the stove. The treatment of giving rabbit organic fertilizer showed a significant to very significant effect on all observed variables except for the maximum number of leaves and fruit oven dry weight which showed no significant effect. The interaction between the treatment of the effect of MKP fertilizer with organic rabbit fertilizer had a very significant effect on maximum plant height, significantly affected the maximum number of leaves, number of flowers, total fruit number, fruit fresh weight, fruit oven dry weight and oven dry weight of the stove.
