Abstract

The effects of nitrogen fertilizer on agronomic and morphological characters depend on several factors such as genotypes and nitrogen rate. The study was aimed to evaluate nitrogen effects on rice panicle. A field experiment was conducted at Babakan Research Station during November 2015- February 2016 using a split-split plot design with three replicates. Nitrogen doses was a main plot, genotypes was a subplot, and time of application was a sub-subplot. A greenhouse experiment was carried out at PAIR, Jakarta during February-July 2017 using a completely randomized design with three replicates. The results from the field experiment indicated that the highest panicle number (13.25), number of filled grains (177.94) and spikelet number (213.76) were obtained at doses of 450 kg urea ha-1. Analysis of variance showed that the genotypic effects were significant for all traits observed, while the interaction effect between genotypes and time of nitrogen application was significant on the length of first grain from first node. However, the three-factors interactions were not significant for all traits. The greenhouse experiment revealed that both genotypes and N rates significantly affected all traits except for panicle number and the length of first grain from first node, respectively, while their interaction only significant for number of primary branch. Nitrogen increased all traits observed except the length of first grain from first node. Simultaneously, both experiments showed significant effects of genotypes for all traits observed. Doses of urea fertilizers above 400 kg ha-1 could improve the performance of panicle traits in order to increase yield potential.

Abstract

As one of the silica (Si) accumulator, rice (Oryza sativa L.) requires large amounts of silica for growth. This study aimed to determine the effect of liquid silica fertilizer application on lowland rice growth and yield, and its roles in drought stress responses. The experiments were conducted at Sawah Baru rice field and Cikabayan Greenhouse Experiment Station, IPB, Bogor during the period of January to May 2016. The field experiment was set up in a randomized complete block design with 7 treatments and three replications. The greenhouses experiment was arranged in a split-plot randomized block design with 3 replications. The main plots were 5 levels of liquid silica fertilizer application, while the subplot was 5 level of various soil water contents. The results of the field experiment showed that the application of liquid silica fertilizer increased rice shoot dry weight, total and productive tiller numbers, and yield per plant, but did not increase yield per hectare. Meanwhile at greenhouse experiment, it showed that the use of liquid silica fertilizer reduced the number of rice stomata, but did not increase cuticle thickness and grain yield per plant. Silica application was not effective to alter drought in rice.

Abstract

Maize is commonly developed in dry land areas with limited irrigation water in Indonesia, thereby posing a threat to its poductivity. Thus, availability of early harvest varieties able to adapt to limited water is important. The aim of this study was to analyze the performance of maize hybrid genotypes candidates in dry land. The research was conducted from April to July 2016 at Gowa, South Sulawesi. The experiment   was designed with a randomized complete block design consisting of 8 genotypes, namely GJ1, GJ2, GJ3, GJ4, GJ5, GJ6, GJ7, GJ8, and two control varieties, i.e., Bima 7 and Lamuru.  The results showed genotypes GJ1, GJ6, GJ7 and GJ8 had higher plant growth as compared to Bima 7 and Lamuru.  All genotypes were harvested less than  90 days. Genotypes GJ6, GJ7, and GJ8  yielded 6.85 tons ha-1, 6.51  tons ha-1 and 8.31 tons ha-1, respectively, which were higher 13-45% than the Lamuru control variety. Because this experiment was carried out in an optimun condition, it would be necessary to further study the three genotypes in drought stress conditions before being developed for early harvest and high yielding hybrid varieties.

Abstract

The imbalanced supply-demand of soybean is the main reason of soybean import in Indonesia. One of the efforts to increase of soybean production was expanding the planting area to acid soil with a low pH, high content of Aluminum, and low nutrient availability, through giving ameliorant, such as liming organic materials, and mineral fertilization.This study was aimed to obtain the best combination of fertilizer and amelioran for soybean production in acid soil. The study was conducted in experimental station of Tenjo, Bogor from November 2015 to March 2016. The experiment used a randomized complete block design with two factors. The first factor was combinations of fertilizer and amelioran, i.e., P0 (without fertilization); P1 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) ha-1}; P2 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 1,250 kg of manure ha-1}; P3 {50 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P4 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P5 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) ha-1}; P6 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomites 1 x Aldd (3,220 kg) ha-1}. The second factor was soybean varieties of Tanggamus and Anjasmoro. The results showed that application of 75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) produced the highest productivity (2.91 ton ha-1), but it was not different from reducing the dose of dolomite into ¼ x Aldd (805 kg) with the addition of 2,500  kg of manure.

Abstract

Most salt-affected agricultural land has low productivity such that suitable management is required to improve the productivity. Negative effect of salinity stress can be reduced by growing salt-tolerant cultivars and soil amelioration. The objective of the research was to identify effective ameliorant and effect of mulching in improving soybean growth and yield on saline soil. The research was conducted on saline soil in Lamongan District that has electrical conductivity (EC) of  11.39 dS m-1 during dry season 2016. Treatments consists of two factors that were arranged in split plot design, and replicated three times. The main plot was mulching, i.e. without mulching and mulching with 3.5 ton ha-1 rice straw. The subplots were six amelioration traits, namely without amelioration (control), 120 kg ha-1 K2O, 750 kg ha-1 S, 5 ton ha-1 gypsum, 5 ton ha-1 manure and combination of 5 ton ha-1 manure+1.5 ton ha-1 gypsum. The soybean seed used was K-13, a saline tolerant genotipe. The results showed that mulching reduced soil EC, increased K and Ca absorption, leaf chlorophyll index, improved growth and yield. Soil amelioration with K2O, sulphur, gypsum, or combination of manure+gypsum decreased soil EC and soil pH.  Amelioration with gypsum increased the grain yield of 36.3%.

Abstract

Basil (Ocimum basilicum L.) is a plant that has great potency  to be developed. Almost all parts of the plant can be utilized. This study aimed to determine the effect of shade and phosphate fertilizer on growth and essential oil content in  basil. This research was conducted at the experimental field of Agrotechnology Departement, Faculty of Agriculture, University of Trunojoyo Madura, during January-April 2015. The research was arranged in a split plot design with 3 replications. Main plot was shading i.e., without shading  and 25% shading. The subplots were phosphate fertilizer rate, i.e., 0, 1.5, 3.0, and 4.5 g SP36 per plant that was planted in polybags. The results showed that plants treated with 25% of shading and applied with phosphate 3 g per plant had the highest total dry weight, production of essential oil and eugenol. Shading of 25% give the best results on plant height, leaf area and total fresh weight of the plant. Application of phosphate fertilizer 3 g per plant give  the highest content of chlorophyll (chlorophyll b and total chlorophyll), while the highest essential oil and eugenol content of leaves is obtained from application of phosphate fertilizer 3 and 4.5 g per plant. Shading  and phosphate fertilizer application did not affect leaf  number.

Abstract

Black cumin (Nigella sativa L.) is an introduced medicinal plant therefore requires investigations to establish recommended cultivation procedure in tropical areas. Black cumin seeds contain a various bioactive compounds not only for culinary but also for medicinal purposes. This study was conducted to investigate the effect of nitrogen rates and shade levels on growth of Black cumin. The activity was carried out in Pasir Sarongge experimental station, Cianjur, West Java (1,117 masl). The research was arranged in nested design with three replications.  Nitrogen rates was nested within shading levels. The shading levels consist of 0%, 25%, 50%, and 75% which resulted in light intensity of 27,800, 17,400, 11,900, and 1,600 lux respectively. The Nitrogen rates consisted 0, 60, 120, and 180 kg ha-1. The results showed that shading up to 50% did not affect plant growth and did not reduce seed production. However, shading up to 75% prolong the vegetative period, decreased leaf thickness and plant dry weight. The higher the shading level up to 50%, the higher the plant height, leaf area, number of leaves and number of flower, but not number of branche. Nitrogen fertilizer 60 kg ha-1 increased number of blooming flower and number of capsule set.

Abstract

Sugar cane is a strategic commodity for the Indonesian government as raw material for the national sugar industry. Cultivation of sugar cane has been shifted to dry areas dominated by Inceptisol, Vertisol, and Ultisol soil. These conditions require certain clones to obtain high sugar yield. New improved varieties have been developed and 8 early-mid maturiting clones have been obtained. The study was aimed to evaluate and obtain earty-mid maturing clones with higher sugar yield than the existing varieties in dry land of Inceptisol soil. The study was conducted at the Karangploso Experimental Station, Malang from July 2015 to September 2016. The study was arranged in a randomized block design with three replications. The treatment consistsed of eight clones of early to mid maturing sugarcane clones and one control variety (Kenthung). The eight clones were (1) PS 04 117, (2) PS 04 259, (3) PS 04 129, (4) PS 05 258, (5) PS 06 391, (6) PS 06 370, (7) PS 06 188, and (8) JR 01. The results showed that three clones (PS 06 188, PS 05 258 and JR 01) produced higher sugar yield (10.45-11.88 ton ha-1), and the other clones showewd lower sugar yield (6.55-9.37 ton ha-1) than that of Kenthung variety (9.16 ton ha-1).PS 06 188 and PS 05 258 clones obtained the highest sugar yield of 11.88 and 11.49 ton ha-1, respectively.
