Title

The Effect of Pollination Models on Yield of Red Pitaya (Hylocereus polyrhizus) Renfiyeni Renfiyeni
JERAMI : Indonesian Journal of Crop Science Vol 1 No 1 (2018): JIJCS
Publisher : Department of Crop Science, Faculty of Agriculture, Andalas University

Red pitaya is getting more popular in Indonesia recently as one of high antioxidant sources with a promising economic value. However, the production of this CAM plant is restricted by low success percentage of its natural pollination and self incompatibility problems. Therefore, artificial pollination is required to overcome these problems and increase its yield. This study was aimed to evaluate the effect of pollination models towards the yield of red pitaya. This study was conducted using randomized block design with three pollination models applied into nine groups. Pollination models used were open pollination (P1), hand-self-pollination (P2) and hand-cross pollination (P3). Several floral-related parameters, including the elongation of flower bud, diameter of blooming flower, length of stigma, number and length of anthers, were assessed. Effect of different pollination models was also observed through some yield-related parameters, such as fruit weight, fruit diameter, fruit length, harvesting age and number of fruit sets. This study revealed that hand cross pollination produced the best yield performance showing 541.1 gram of fruit with 11.5 in length and 8.66 cm in diameter. Harvesting age and number of fruit sets showed no significant difference among those three pollination models. Keywords: Pollination, red pitaya, yields, fruits, flowers

Abstract Sugarcane is the main sugar-producing plant in the world and also plays an important role as a raw material for bioethanol production. Productivity improvement of the plant is exposed to environmental stress ie: water shortage which is currently a serious problem associated with the global climate change phenomenon. Understanding of plant responses to environmental stress is one of the keys to be able to resolve the issue. In this regard, the fundamental studies related to the sugarcane plant responses to water stress is very important. This study consists of a combination of two factors, namely the type of clones consisting of PS.864, PSJT.941, and VMC.76-16, 851 as tolerant group clones, PS.862, PS.882 and PS.851as non tolerant clones group and lack of water stress treatment for 5 days. The data were analyzed further using DNMRT at 5% significance level. Observations showed that tolerant clones as well as non-tolerant clones PS.862 showed better resistance response than non tolerant groups. The indication was shown by the value of the Relative Water Content (RWC), Specific leaf area (SLA) and Water Deficit Value (WDV). Total protein profiling of sugarcane grown under water deficit and its counterpart differentially distinguished by suppression of protein expression of about 35 kDa in all clones. While in the water deficit condition expression of a protein with a size of 25 kDa is remarkable expressed.

Research on the effect of Quail Manure on the Growth and Yield of Shallots (Allium ascalonicum L.), has been carried out in Jorong Lima Ninik, X Koto Singkarak District, Solok Regency with an altitude of ± 400 m above sea level. This study aims to obtain the best dose of quail manure for the growth and yield of shallots. The method used was a Randomized Block Design (RAK) with 6 treatments, 4 groups. The treatment given was the dose of quail manure namely, as follows: P1=0 g/polybag, P2=30 g/polybag, P3=60 g/polybag, P4=90 g/polybag, P5=120 g/polybag, P6=150 g/polybag. The research data were analyzed for variance if the calculated F was greater than F table 5%, followed by Duncan's New Multiple Range Test (DNMRT) at a 5% significance level. Parameters observed were plant height (cm), number of leaves (strands), number of tubers (fruit), wet weight (g), dry weight (g). The results showed that the application of quail manure had a very significant effect on plant height, the number of leaves, wet weight, and dry weight of shallot bulbs. The best results were obtained from the P5 treatment (120 g/polybag) with a production of 78.25 g/plant.

This study aims to obtain the composition of soil and cow dung that provides the best growth for kepok banana seedlings using banana corm.. This research was conducted in Sijunjung Regency. Efforts to provide banana seeds are carried out by utilizing banana corm which will produce 3 and 4 tillers per tuber and the production time is much faster than seeds from tillers. To get the best banana corm growth, a study was conducted using a mixed planting medium of soil and cow manure with five comparisons. The treatments were: A. Soil with cow manure 1:1 ratio, B. Soil with cow manure 2:1 ratio, C. Soil with cow manure 3:1 ratio, D. Soil with cow manure 4:1 ratio, E .Soil only. The treatment was repeated 5 times. The design used was a randomized block design and continued with DNMRT (Duncan New Multiple Range Test). Parameters observed were when shoots appeared, percentage of growth, shoot height, stem diameter, number of leaves, leaf length, root length and number of roots. The results showed that the best planting medium for planting banana kepok from corm was a medium consisting of soil and cow manure with a ratio of 1:1. This treatment gives the best results for all parameters.
