PENGARUH INTENSITAS PEMOTONGAN TERHADAP PRODUKTIVITAS Indigofera zollingeriana

THE EFFECT OF DEFOLIATION INTENSITY ON PRODUCTIVITY OF Indigofera zollingeriana. This research aims to know the effect of defoliaion intensity on productivity (fresh production, dry weight production, proportion of leaves and stems) and to know the defoliation intensity with optimal productivity of forage Indigofera zollingeriana. This research was conducted in December 2019 until March 2020. It consisted of defoliation intensity at 75cm (T75), 100cm (T100), 125cm (T125), and 150cm (T150). The design used in this experiment is Completely Randomized Design. The variables in this research were 1. fresh production leaves and stems; 2. dry weight production leaves and stems; 3. the proportion of leaves and stems dry weight production of forages Indigofera zollingeriana. The results showed that the difference of intensity defoliation had a significantly effect (P<0,01) on productivity (fresh production, dry weight production, proportion of leaves and stems) forage Indigofera zollingeriana. Defoliation intensity 75 cm have significantly (P<0,01) fresh and dry weight leaf of Indigofera zollingeriana than hight defoliation 125 cm and 150 cm. Intensity defoliation 125 cm have significantly (P<0,01) leaf-stem ratio of Indigofera zollingeriana than any other. It conclude that intensity defoliation 125 cm have highly productivity.   Keywords: Indigofera zollingeriana, cutting intensity, productivit

PEMANFAATAN BOKASHI FESES SAPI TERHADAP PRODUKTIVITAS RATUN SORGUM VARIETAS KAWALI

UTILIZATION OF BOKASHI FESES COW ON PRODUCTIVITY RATOON OF KAWALI SORGHUM VARIETY. This study aims to determine the effect of bokashi cow feces on the productivity of ratoon sorghum variety of kawali. This research was implemented in Wusa village at districts Talawaan. The design used was completely randomized design (CRD), which consists of 4 treatments and 5 replications to obtain 20 units of trial. The treatment consists of P0= without fertilization, P1= 4 kg of fertilization, P2= 8 kg of fertilization, P3= 12 kg of fertilization.  The measured variables are number of tillers, plant height, and panicle weight. Result of the analysis showed that treatment with 12 kg/plot provides highly significant effect (P <0.01) of the number of tillers, plant height, and panicle weight compared with other treatments, ie 8 and 4 kg/plot. The HSD test indicated that treatment number of tillers showed that between treatment P3, P0, P1, and P2 showed highly significant. In the treatments of advanced test HSD indicated also that plant height between P3, P0, P1, and P2 showed highly significant. In the treatment of panicle weight of advanced test of HSD showed that between treatment P3 and P0, treatment of P3 and P1 is very different, but the treatment of P3 and P2 showed no significant difference. Based on this research it can be concluded that cattle feces bokashi as the organic fertilizer up to 12 kg produced the best effect on number of tillers, plant height, and panicle weight. Keywords: Bokashi, productivity, ratoon, sorghum, kawal

The purpose of this research was determines growth of sorghum BMR with different population density use chicken manure fertilizer in an elevated state. This experiment was conducted using Completely Randomized Design (CRD). The treatment consisted of four planting density, (P1=(1 plant/Polybag) P2=(2 plants/polybag) P3=(3 plants/polybag) P4=(4 plants/polibag), each treatment had seven replications. Data were analyzed using analysis of variance and HSD test. The variables measured were growth that are plant’s height, leaf length, and number of leaves. The results showed that different planting population were significant different (P&lt;0.01) on plant’s height, leaf length, and number of leaves. HSD test showed that planting population P1=(1 plant/Polybag) were significant (P&lt;0.01) have higher plant’s height, leaf length, and number of leaves than P3=(3 plants/polybag) and P4=(4 plants/polybag). It can be concluded that planting density P1=(1 plant/Polybag) have the highest growth of sorghum BMR that were highest plant’s height, leaf length, and number of leaves

This study aims to determine the growth response i.e stolon length, number of nodes, number of phytomers, and number of tillers of Brachiaria humidicola cv Tully with bokashi organic laying hens fertilizer. The completely randomized design was applied using four treatments and five replications for each treatment. The treatments were assigned level of bokashi. The levels of bokashi that B0 = 0 tons/ha (control), B1 = 2 tons/ha (1.8 kg/plot), B2 = 4 tons/ha (3.6 kg/plot) and B3 = 6 tons/ha (5.4 kg/plot). The variables measured consisted of stolon length, number of nodes, number of phyitomers, number of tillers. The Results of analysis of variance showed that treatment very significantly different (P <0.01) on stolon length, number of phyitomers, number of tillers and significantly different (P <0.05) on the number of nodes. Test of Honest Significance Difference (HSD) showed that B1 (1.8 kg / plot), B2 (3.6 kg / plot), and B3 (5.4 kg / plot) have higher length of stolone, number of phyitomers and number of tillers than B0. B3 and B2 had higher numbers of nodes than B0.

PENGARUH PEMBERIAN PUPUK KANDANG AYAM TERHADAP PERTUMBUHAN TANAMAN SORGUM SEBAGAI PAKAN

EFFECT OF APPLICATION OF CHICKEN MANURE FERTILIZER ON THE GROWTH OF SUPER-1 SORGHUM VARIETY GROWTH. Sorghum (Sorghum bicolor (L.) Moench) is a potential cereal crop to be cultivated and developed as a ruminant’s fodders in Indonesia, specifically in marginal and dryland areas.The purpose of the present study was to determine the effect of chicken manure as a fertilizer on the growth parameters of super-1 sorghum.This study was conducted using a completely randomized design (CRD) which consists of 4 treatments and 5 replicates in each treatment, with a total of 20 experimental units, was used as experimental design. After a significant F test, Tukey’s test (where necessary) was used to inspect treatment differences among group means. Statistical significance was accepted at P &lt; 0.05. Treatments were formulated as follow: P0 = no fertilizer (as a control), P1 = chicken manure fertilizer of 3.5 tonnes/ha, P2 = chicken manure fertilizer of 4.5 tonnes/ha, and P3 = chicken manure fertilizer of 6.5 tonnes/ha. Variables measured were: plant height, leaves count, and leaves length. Research results showed that treatments gave a significant effect (P &lt;0,05) on plant height, leaves count, and leaves length. Chicken manure fertilizer of 6.5 ton/ha (P3) had a higher plant height, leaves count, and leaves length values compared with P0 (without fertilizer), P1 (chicken manure fertilizer of 3.5 tonnes/ha), and P2 (chicken manure fertilizer of 4.5 tonnes/ha). It can be concluded that the application of chicken manure fertilizer up to 6.5 tonnes/ha gives the best effect on plant height, leaves count, and leaves length of sorghum crops as a fodder . Key words: Chicken manure fertilizer, Growth, Sorghum, Fodder
