Abstract

ABSTRACTThe harvest of cassava usually conducted by farmers in Lampung province is around 7 months after planting (MAP).  Moreover, either farmers or industry cassava rarely fertilized by using potassium (KCl) and also micro fertilizers to improve the cassava production.  This condition could decrease the production both root weight and strach content.  Consequently, the objective of this study was to evaluate the cassava production applied by potassium and micro fertilizers harvested at 7 and 10 MAP.  Treatments were arranged by factorial (2x2) in completely randomized block design with three reps used as block.  First factor were First factor was two levels of KCl, 200 and 300 kg KCl/ha.  Second factor was two levels of micro nutrient, 0 and 20 kg zincmicro nutrient/ha.  The result showed that there was no variation of root number and root weight due to application of potassium and micro fertilizers.  This means that root number and root weight were not significantly different applied by potassium and micro fertilizers.  In addition, application of potassium and micro fertilizers could significantly influence shoot growth as stem dry weight and leaf dry weight at 10 MAP.Keywords: harvest, leaf dry weight, micro fetilizer, potassium, production, stem dry weight ABSTRAKCara panen ubikayu yang biasa dilakukan di tingkat petani adalah sekitar tanaman umur 7 bulan setelah tanam (BST).  Selain itu, petani maupun pihak industri sangat jarang melakukan pemupukan kalium (KCl) maupun unsur mikro untuk perbaikan produksi ubikayu.  Hal ini akan menyebabkan penurunan produksi baik dari bobot ubi maupun kadar pati.  Oleh karena itu, tujuan penelitian ini adalah untuk mengevaluasi produksi ubikayu akibat aplikasi pemupukan kalium (KCl) dan mikro pada umur panen 7 dan 10 BST.  Perlakuan disusun secara faktorial (2x2) dalam rancangan kelompok teracak lengkap (RKTL) dengan tiga ulangan sebagai kelompok.  Faktor pertama adalah aplikasi dua dosis pupuk KCL, 200 dan 300 kg KCl/ha.  Faktor kedua adalah aplikasi dua dosis pupuk mikro, 0 dan 20 kg Zincmikro/ha.  Hasil menunjukkan bahwa tidak ada variasi pada variabel jumlah ubi dan bobot ubi akibat pemupukan kalium dan mikro.  Hal ini menggambarkan bahwa aplikasi pupuk kalium dan mikro menghasilkan jumlah ubi dan bobot ubi yang tidak berbeda.  Selanjutnya, aplikasi pupuk kalium dan mikro memberikan pengaruh pada variabel pertumbuhan tajuk seperti bobot kering batang dan daun pada umur 10 BST.Kata kunci: bobot kering batang, bobot kering daun, kalium, mikro, panen, produksi

Abstract

North Lampung Regency is the main producer of Lampung black pepper, which is generally in the form of a poly-culture system of pepper cultivation. This study aims to study the performance and productivity of the pepper plant which is intercropped with coffee by farmers in North Lampung. This study used a survey method and conducted in North Lampung by taking 2 samples of the sub-districts purposively, namely Abung Barat and Abung Tengah. From each district, 2 villages were selected purposively. Primary data were collected by interviewing 93 sample farmers who were randomly sampled. To deepen the performance of planting, visits and observations of farmers' fields were conducted. The results of this study concluded that: (1) 96% of farmers applied a poly-culture pepper plantation system. Intercropping pepper plantations have a lower pepper plant population but the presence of intercropping can cause land use efficiency to increase by up to 30%;(2) The poly-culture pepper fields  are managed less intensively as indicated by the low fertilizer dosage and the high mortality rate of pepper, which reaches 7-10% of plants per year; (3) The productivity of this intercropping system is pepper yield (conversion of SPH 1600 trees / ha) reaching 230-260 kg / ha or based on factual population reaching 155-267 kg/ha, coffee yield 166-221 kg/ha, and yield of Pithecellobium jiringa 24 -28 kg/tree; (4) According to farmers' perceptions, the main constraints faced by farmers (80.2% of farmers) were the attack of pepper foot rot disease, low prices for pepper, and high mortality of pepper trees. However, most farmers (88.9% of farmers) said they would not replace pepper with other crops.Keywords: Black pepper, coffee, Pithecellobium jiringa, poly-culture, yield

Abstract

The multiple cropping system is one of the cultivation systems that is suitable for increasing land productivity, especially those with low fertility levels. The main problem with the intercropping cropping pattern is competition between plants. The correct timing of planting can minimize the negative effects of competition between plants so that it can optimize plant growth and production. The purpose of this study was to determine the best planting time in the intercropping pattern of sweet corn and edamame soybeans. The treatments consisted of 4 types in planting time: edamame soybeans monoculture (T0), edamame soybeans were planted simultaneously with sweet corn (T1), edamame soybeans were planted 7 days before sweet corn (T2), and edamame soybeans were planted 14 days before sweet corn (T3). The results showed that the difference in planting time did not lead to suppress of the growth of edamame soybeans at different planting times with sweet corn in the intercropping system compared to monoculture system. So that we can apply the same planting time between edamame soybeans and sweet corn in intercropping system.Keywords: Ademame, growth, intercropping, optimize, planting time

Abstract

The development of superior peanut cultivars can be conducted through the steps of enhancement of genetic variation, inbreeding, selection, and yield trials. Genetic variation can be enhanced through sexual hybridization (crossing). The objectives of this study were 1) to determine the rate of success of artificial hybridization between runner/semi-runner and Spanish/upright type of peanut;  2) to know the phenotypic characters of the growth habit, pod size, and number of seeds per pod in peanuts. The F1 phenotype is related to the estimation of gene action. This study consisted of two experiments, namely hybridization and evaluation of the type of growth of the F1 family. The experiment was conducted in the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The genotypes of parents included national cultivars Bima, Bison, Gajah, Jerapah, Talam, and  Kelinci;   and introduced runner/semi-runner genotypes  K / SR-3 (runner) and NC 7 (semi-runner). The results showed that  NC 7 x Bison  showed the highest ratio of the number of gynophores (NG) / number of flowers crossed (NFC) (31%); NC 7 x Kelinci showed the highest number of pods (NP) / NG ratio  (78%);   and Bima x NC 7 showed the highest NP / NFC (13%). The percentage of F1 plants showing semi-runner growth habit  was 85%, producing pods with two seeds was 100%, and producing large pods was 89%. Keywords:  Growth habit, pod size, the rate of artificial hybridization, seed number

Abstract

Mangosteen (Garcinia mangostana L.) is a tropical plant that bears seasonal fruit and is one of Indonesia's leading export commodity.  Mangosteen production in Indonesia is still low and not continuous, because there are several factors that influence it.  One of them is the character of biennial bearing in mangosteen one year produce high fruit load followed by a next year of very low production.  Therefore it is necessary to induce off season mangosteen flowering.  This study aims to determine: (1) the effect of Paklobutrazol on the flowering of mangosteen plants, (2) the effect of adding KNO3 and Etefon on the acceleration of mangosteen flowering.  This research was conducted in Mulangmaya Village, Kota Agung Timur District, Tanggamus, Lampung.  Regency at an altitude of 250 m above sea level from September 2018 to April 2019.  This research used a Randomized Block Design (RBD) with a single factor consisting of 3 treatments, namely P1 ( manure 10 kg/plant + NPK Nitrophonska 1 kg/plant, P2 (Paclobutrazol 2 ml/l + KNO3 20 g/l + manure 10 kg/plant + NPK Nitrophonska 1 kg/plant), and P3 (Paclobutrazol 2 ml/l + Etefon 40 ml/l + manure 10 kg/plant + NPK Nitrophonska 1 kg/plant).  The data obtained were analyzed by analysis of variance and the mean separation was carried out by orthogonal contrast test at the 5% significance level.  The results showed that the treatment of P2 (Paclobutrazol 2 ml/l + KNO3 20 g/l + manure 10 kg/plant + NPK Nitrophonska 1 kg/plant) on mangosteen plants was able to spur flowering faster with a difference of 12 days (8.70% ), and increased the total number of fruits per plant by a difference of 41 fruit (38.80%).  The P3 treatment (Paclobutrazol 2 ml/l + Etefon 40 ml/l + manure 10 kg/plant + NPK Nitrophonska 1 kg/plant), unexpectedly causing significant leaf drop 3 days after Ethephon spray, and new leaves were formed a month later.  Keywords : Ethephon, KNO3, Paclobutrazol, and mangosteen flowering
