Abstract

One of the factors hindering the development of upland rice cultivation among annual crops is the limited number of shade-tolerant upland rice varieties. It is very important to assemble shade-tolerant upland rice varieties with high yields. The purpose of the study was to determine the effect of shade on the growth and productivity of five genotypes of upland rice. This research was carried out in the experimental garden of the Faculty of Agriculture, the Islamic University of North Sumatra with an altitude of 25 m above sea level, from June to December 2020. The research design was split-plot and repeated three times. The main plot of shade treatment consisted of two levels, namely no shade (0%) and shade treatment (70%). The sub-plots were five genotypes of upland rice in Deli Serdang and two shade-tolerant varieties. Shade treatment affected the growth and productivity of five genotypes of upland rice in Deli Serdang District (Sialus, Arias, Ramos Merah, Silayur, and Sirabut) and two shade-tolerant varieties (Rindang 1 and 2). Two genotypes of upland rice were obtained, namely Silayur and Sirabut which were more shade tolerant, based on flowering age, harvest age, and grain weight per clump. When compared with Rindang 1 and 2 varieties, the two genotypes of upland rice were the same or more tolerant.

Abstract

Specific changes in morphology, anatomy, biochemistry and molecular occur due to changes in light intensity. Changes in growth is closely related to the mechanism of plant resistance when low light conditions. In addition, the environmental stress conditions of supply nutrients plants need in order to remain able to grow optimally. This experiment was conducted in experimental garden Sawah Baru, Post-harvest Laboratory and Micro-engineering Laboratory Bogor Agricultural University, beginning in December 2014 until July 2015. This experiment was aims to determine the effect of shade and fertilization on the growth and change of morpho-anatomy of leaves jack bean. The experiment was arranged in a split plot design based on randomized complete block design. Shade as the main plot that consists of three levels: without shade, shade 25% and 50% and combination doses of fertilizer as a subplot which consists of three levels ie: 50 kg urea ha-1 + 100 kg SP-36 ha-1 + 75 kg KCl ha-1, 75 kg urea ha-1 + 125 kg SP-36 ha-1 + 100 kg KCl ha-1, 100 kg urea ha-1 + 150 kg SP-36 ha-1 + 125 kg KCl ha-1.The results showed increased percentage of shade caused etiolation, reduction number of branches, change the leave size, depletion of palisade tissue which decreases the thickness of the leaves, and decreased of pod/plant.Whilefertilizationfactoronlyinfluence onthe thickleaves andthickpalisade.

Abstract

Plantation of PT. Tidar Kerinci Agung (PT. TKA) is a company engaged in oil palm plantations with an area of 24,000 ha and has been certified by Indonesia Sustainable Palm Oil (ISPO). PT. TKA has a factory for Crude Palm Oil (CPO) processing, therefore the local community can sell their palm oil yield to the factory. However, the purchase of Fresh Fruit Bunches (FFB) from the community was constrained by the fact that many people use random seeds which reduce the quality of CPO, moreover the agronomic factors such as fertilization, rainfall, plant maintenance and harvesting on smallholder plantations which are the factors that can reduce the quality of CPO. The present study was conducted for 3 months, with the objective was to determine the comparison of the palm oil extraction rate between smallholder plantations and large-scale estate (PT. Tidar Kerinci Agung). The research method was a survey by purposive sampling to obtained data on oil palm production, especially in relation with oil extraction rate. The result showed that the oil extraction rate of CPO was 24.51% and it’s on Palm Kernel Oil (PKO) was 4.45% in large-scale estate (PT. TKA). It was higher than the oil extraction rate on smallholder plantations. The oil extraction rate of CPO and PKO in the high yielding, moderate yielding, and low-yielding smallholder plantations were CPO 20.55% and PKO 4.42%, CPO 21.50% and PKO 3.77%, and CPO 18.35% and PKO 4.34%, respectively.

Abstract

Avocado is a cross-pollinated plant that has many variations of morphology. The study aimed to classify avocado accession based on morphological characters and to evaluate avocado accession based on predefined idiotype. The research has been conducted in January and February 2015 in three sub-districts in Solok District, representing lowland, middle and highland. The characters observed were morphological characters, both qualitative and quantitative in accordance with Descriptors for Avocado (IPGRI 1995). The calculation of genetic distance between accessions was done by Gower method. The selection of idiotypes has been done by collecting information on consumer preferences on the characteristics of avocado from fruit shops, fruit traders in traditional markets, farmers, and consumers. The results showed that 21 avocado accession of Solok regency can be grouped into two main groups, namely Idal 3 avocados and 20 other accessions. The coefficient of dissimilarity between the two groups is about 45% or with a similarity of 55%. Accessions that have many superior characters are the accession of Idal-1, Zainal and Asni-2.
