KADAR HORMON AUKSIN PADA TANAMAN KENAF (Hibiscus cannabinus L.) BERCABANG DAN TIDAK BERCABANG

Kenaf is one of fiber producing plants. According to the existence of branches, kenaf is classified into two group, consisting of: kenaf with branch and with no branch.Morphology observation, consist of the height of plant, the number of node, the number of branch and the length of branch was observed. The morphology observation showed that there were differences morphological characters, including of the height of plant, the number of node, the length of branch, and the number of node more branching kenaf, control non branching (KR11) and control branching (SM004).Non branching plants (KR11) have the highest habitus and smallest number of branch compare to other groups. Control branching (SM004) was the shortest habitus and greatest number of branch compare to other group. The highest of Non branching plants (KR11) 230,6 ± 36,7 cm and the smallest control branching (SM004) 116,3 ± 64,4 cm. The greatest number of branch found in controled branch SM004, with 5,6 ± 2,7 branch in every plant and the smallest is KR11 with 0,8 ± 0,8 branch in every plant.According to this research the length of plant influence the branch. The highest level of auxin were in the shoot tip and the lowest level were in root tip. The higher auxin will produce less branch, the lower auxin will produce more branch

Pemupukan SP36 pada Lahan Regosol Bereaksi Masam Terhadap Pertumbuhan dan Hasil Dua Varietas Kacang Tanah (Arachis hypogea L.)

The  aim of this research was to know the effect phosphate dosage on a regosol soil to peanut variety growth and yield.  The research was conducted in peanut field.  It used a Randomized Complete Block Design (RCBD) ordered faktorially and consisted of two faktor with three replication. The first faktor was the fertilizer dosage of phosphorus of 0, 125, 250 and 325 kg ha-1 of SP36 respectively.  The second faktor was the peanut variety of genol and bima variety.  The result showed that amount of phosphorus influence to growth of peanut variety, especially:  the amount of branches and leaves (8, 11 weeks after planting), dry matter (dm) of leaves, branch and all plant, dry matter of pod per plant. The phosphate dosage of 325 kg ha-1of SP36 result the best of growth and yield (dm of pod per plant) peanut.  The genol variety of peanut have the best of amount of branch, leaves, dm leaves, branch and all plant, percentase of  flowers to pod, weigth of 100 seeds. The bima variety is only the best to amount of seed per pod and per plant

An centration compon fertilize giving best influence  0,35%,between situation of seed in fruit with concentration fertilizer compon  of thuse no interaction in influencing growth of seed kakao plant

Periode Kritis Kacang Hijau (Phaseolus aureus L.) Akibat Persaingan dengan Gulma dan Macam Pengolahan Tanah pada Tanah Mediteran Merah di Desa Socah Kecamatan Socah Bangkalan

Mung bean is one of leguminose plants planted in the third  order after soy bean and ground nut.  The presence of weeds on certain growth periode (critical periode) and at certain population can cause to reduce the yield of this plant.  This research aimed to study the critical periode of mung bean as the affected by the presence of weeds on different soil tillage.  The study was carried out on horticulture station research, Socah District, Bangkalan Regency with red mediteran (Alfisol) soil type. The research was arranged in a randomized block design with two factors. The first factor was the clear away weed consisted of  8 levels and the second factor was soil tillage method consisted two levels.  Result showed that there were significant interaction between the way in clearing away weeds and soil tillage treatment on the plant height, leaf area, leaf number, fresh and dry weight of plant, pod number, and dry weight of seed of plant.  Moreover,  the longer weeds present in assosiation with mung bean plant was the higher the effect of the weeds to reduce the yield. The higher yield was resulted from plant growing on the tilled soil. The critical periode of mung bean plant growing in the competition with weeds on untilled and tilled soil respectivelly was between 2 and 4 weeks after planting and between 6 and 8 weeks after planting

Kompatibilitas dan Efektifitas Fungi Mikorisa Arbuskula (FMA) terhadap Kacang Komak (Dolichos lablab L)

Besides, low nutrient availability  the problem in  dry land of Madura  is  the conflict  of land use  for food crops and  forage  production. Overcoming the problem  a program that  unite agriculture and husbandry activities is needed.  The objective of this research was to find out the most compatible and effective isolate of AMF on hyachinth bean (Dolichos lablab L)  as a forage legume.  The AMF which were   Gigaspora sp, Glomus sp, Glomus manihotis, Acaulospora sp dan Entrophosopra sp  were  planted beneath the bean seeds in polybag and   the plants were managed in a green house in optimal condition. The result showed that among isolates of arbuscular micorrhizal fungi, Gigaspora sp. greatly influenced growth and yield of biomass of hyachinth bean (Dolichos lablab L) indicating dependency of the plant to the fungus.  It is concluded that Gigaspora sp is the most compatible isolate for legume of hyachinth bean (Dolichos lablab L)

Pengaruh ZPT terhadap Kualitas Buah Manggis

The objectives of this experiment was to examine the influence of polyamine, gibberellin and harvesting times to inhibit ripening process and to maintain the postharvest quality on mangosteen. The method applied was a randomized block design with two factors and three replications. First factor was harvesting time consisting of 14, 15 and 15 weeks after anthesis. Second factor is chemical concentration consisting of control (aquadest), GA3 (150, 200, 250 mg/l), polyamine (0,3; 1 and 3 mM). The result showed that spermidine application at 1 mM was more effective to maintain the postharvest quality of mangosteen, the fruit remained soft and the climacteric peak was longer than that of control. Gibberellin application showed unsightly result compared to control. Mangosteen fruits with harvesting time of 15 and 16 weeks after anthesis had better performance than those of harvesting at 14 weeks after anthesis, the fruit has remained soft and the weight loss was less

Pengaruh Pupuk N, P, K dan Mg terhadap Pertumbuhan dan Kualitas Lidah Buaya (Aloe vera chinensis) pada Lahan Gambut Indragiri Hilir Riau

The objective of this research was to study the effect of N, P, K and Mg fertilizers on growth and quality of Aloe vera chinensis in peat soil of Indragiri Hilir Riau.  The research was conducted at PT Bhumireksa Nusasejati Plantation, Indragiri Hilir Riau.  The research was arranged by Factorial Randomized Block Design  with 4 factors, 4 levels, 3 replications.  The first factor was N dosage fertilizer (N0 is equal to 0g, N1 is equal to 5g, N2 is equal to 10g, N3 is equal to 20g N/plant/month), The second factor was P dosage fertilizer (P0 is equal to 0g, P1 is equal to 4g, P2 is equal to 8g, P3 is equal to 16g P2O5/plant/month), The third factor was K dosage fertilizer (K0 is equal to 0g, K1 is equal to 7.5g, K2 is equal to 15g, K3 is equal to 30g K2O/plant/month), The fourth factor was Mg dosage fertilizer (Mg0 is equal to 0g, Mg1 is equal to 2.5g, Mg2 is equal to 5g, Mg3 is equal to 10g MgO/plant/month).  The results showed that the application of N, K and Mg dosage significantly increased plant height, leaf length, leaf width, leaf thickness, and the number of leaf by quadratic response.  Combination of N and P fertilizer  significantly raised the leaf fresh weight.  The complete treatment (NPKMg) and single factor either N and Mg did not increase the total chlorophyll and protein content , in contrast, P and K as a single factor significantly  increased  the total chlorophyll but not protein content. Gel of Aloe vera consisted of 17 essential amino acid
