The aim of the present study was to evaluate the usefulness of Brassica rapa var. narinosa for field production in Central European climatic zone in order to introduction of this species to large-scale farming. Chinese flat cabbage cultivars, ‘Tatsoi’ and ‘Misome’, were the object of the 2-year-long field experiment in south Poland, conducted in 2 terms: plantings in the middle and at the end of August, harvests in the middle of September and on the beginning of October (1st and 2nd growing period, respectively). Plants were evaluated for morphological and chemical variability at the transplant stage. The yield and bioactive compounds content in the leaf petioles of mature plants were also studied. Analyses of juvenile plants, conducted before transplanting, showed that ‘Misome’ transplants were greater, but they had less leaves then ‘Tatsoi’. Transplants of both cultivars from the 2nd growing period had greater fresh weight, but the content of dry matter, soluble sugars and carotenoids was lower. Total and marketable yield, rosette mass, L-ascorbic acid and crude fibre content were greater for both cultivars planted in the middle of August and harvested in the middle of September. Leaf petioles of Chinese flat cabbage from the 2nd growing period were significantly richer in dry matter and soluble sugars. Only the level of carotenoids and chlorophylls was not influenced by the growing period. ‘Misome’ gave the greater marketable yield of better structure, and had a higher content of biologically active compounds than ‘Tatsoi’, with the exception of crude fibre. In Central Europe conditions, this cultivar should be recommended for plantings in the middle of August to achieve the best yields of high nutrient content.

ABSTRACT The results of three years (2009-2011) of field studies using two types of biodegradable nonwoven covers (aromatic polyester IBWCH 75 g m-2 and polylactic acid PLA 54 g m-2) on the yield, quality and root development of cucumber are presented. Seeds of parthenocarpic cucumber (‘Mirabelle’ F1) were sown directly into the field at the beginning of May/June and covered with nonwoven field covers. A plot that remained uncovered served as the control. The covers were kept in place until the first flowers appeared. Cucumbers were harvested every three days for 5-6 weeks. Fruits were evaluated for dry matter, soluble sugars and nitrate content. After the last harvest, whole plants were harvested and evaluated for weight, surface area, total length and average diameter of the roots. The experiment showed that the covers increased the marketable yield of cucumber in 2009 and 2010 (regardless of the type of polymer), but did not influence the yield in 2011. In 2011 the fruits from the covered plots had higher levels of soluble sugars and dry matter in comparison to the control. The covers did not influence root development.

Abstract Background Entomophagy, the consumption of insects, is a common practice among various tribal communities across the globe. Various factors such as flavour, nutrient content, availability and claimed medicinal values have contributed to the increased consumption of insects. Two commonly consumed insects among the Bodo tribe in Assam, namely, Samia cynthia ricini Boisduval, 1854 (Lepidoptera: Saturniidae) and Dytiscus marginalis Linnaeus, 1758 (Coleoptera: Dytiscidae), were procured from local markets in Kokrajhar and evaluated for their proximate and mineral contents using Association of Official Analytical Chemists (AOAC) guidelines and inductively coupled plasma-optical emission spectroscopy (ICP-OES). Both the insects are available throughout the year and are consumed on a large scale. Results S. cynthia ricini showed higher contents of moisture (7.89 ± 0.020%), ash (4.10 ± 0.077%), fat (22.23 ± 0.209%) and carbohydrate (7.78 ± 0.057%) whereas higher contents of crude fibre (14.28 ± 0.102%), protein (56.37 ± 0.366%) and nitrogen (9.02 ± 0.058%) were observed in D. marginalis. The calorific value of S. cynthia ricini was higher with 430.19 ± 2.241 kcal whereas D. marginalis showed a lower value of 382.58 ± 1.527 kcal. D. marginalis showed the presence of arsenic (As) (0.014 ppm), and sodium (Na) was not detected. S. cynthia ricini did not show the presence of As and magnesium (Mg). Lead (Pb) showed a value of 0.026 and 0.044 ppm, and cadmium (Cd) showed a value of 0.005 and 0.005 ppm in S. cynthia ricini and D. marginalis respectively. Conclusions Both the studied insects showed high protein and fat contents and a high calorific value. Although the insects show the presence of several essential minerals in considerable amounts, they showed the presence of toxic heavy metals in trace amounts. Hence, their consumption must be done in a controlled manner owing to the presence of As, Pb and Cd which are capable of causing adverse reactions in its consumers.

Abstract The objective of this study was to evaluate minerals and nutrient composition of young coconut husk silage fermented with rice bran at different concentrations. The study was conducted for seven months in the Laboratory of Feed Technology of State Agricultural Polytechnic of Kupang. A completely randomised design was employed with four treatments and five replicates. The treatments were young coconut husk without rice bran (P0) or the husk plus 4% (P1), 8% (P2) or 12% (P3) of rice bran out of the silage total weight. Variables measured were dry matter, ash, crude protein, crude lipid, crude fibre, Calcium, Potassium and Phosphorus. Analysis of variance showed that rice bran significantly (P<0.01) affects all variables measured. The Duncan’s range multiple test showed that 12% and 4% were the best rice bran concentrations to increase nutrient content and minerals of the silage, respectively. It can be concluded that adding 12% of rice bran to young coconut husk silage increased dry matter, ash, crude protein and crude lipid but reduced Calcium and Potassium. Crude fibre and Phosphorus increased at the inclusion of 8% rice bran.  Key words: Nutrient; Minerals; Rice bran; Silage; Young coconut husk.   Abstrak Penelitian yang bertujuan untuk mengevaluasi komposisi nutrien dan mineral silase sabut kelapa muda pada berbagai level penambahan dedak padi, telah dilaksanakan selama 7 bulan di Laboratorium Teknologi Pakan Politeknik Pertanian Negeri Kupang, dengan menggunakan rancangan acak lengkap dengan 4 perlakuan yang terdiri dari P0 : sabut kelapa muda tanpa dedak padi, P1 : sabut kelapa muda + 4% dedak padi, P2 : sabut kelapa muda + 8% dedak padi, P3 : sabut kelapa muda + 12% dedak padi dengan 5 kali ulangan.

The article presents the results of biochemical and QTL (Quantitative Trait Loci) analysis of dry matter content, nutrient and biologically active compounds: sugars, ascorbic acid, chlorophylls a and b, anthocyanins and carotenoids in populations of doubled haploid lines of leaf, root crops, and oilseeds of the Brassica rapa L. species grown in optimal light culture conditions, but with different photoperiod durations. The purpose of this study was to evaluate the effect of the photoperiod on the transition to bolting and the accumulation of biologically active substances, as well as how the localization and identification of chromosomal loci determined the content of certain phytochemicals. The influence of the length of daylight hours on the content of components of the biochemical composition was assessed. It was shown that growing under conditions of a 16 h photoperiod increased the content of dry matter, sugars, vitamin C, and anthocyanins. On the contrary, the content of photosynthetic pigments was higher under the conditions of a 12 h photoperiod. Valuable lines that can be sources of biologically active compounds were revealed. Based on the results of the obtained data, 102 QTLs were mapped, which determine the manifestation of the studied biochemical quality traits in the B. rapa doubled haploid lines under conditions of short and long daylight hours. Molecular markers genetically linked to the selected QTLs were determined. It was revealed that the identified loci controlling all the studied biochemical traits were mainly in the fifth, sixth, seventh, and ninth linkage groups, which correlated with the data obtained in the field and greenhouse. Most of the identified loci controlled several studied traits simultaneously. The identified QTLs and identified molecular markers are of interest for further study of the genetic control of the economically valuable traits determined by them and for the implementation of marker-assisted selection in B. rapa. The data obtained can be used in genetic and breeding work, including for the obtaining of new genotypes, lines and cultivars with a valuable biochemical composition, adapted for cultivation under specific photoperiodic conditions.

Abstract Background Understanding the relationship between dry matter yield production and forage quality throughout the growing season will help to optimize the cutting intervals between harvests in different Alfalfa (Medicago sativa L.) varieties. An experiment was conducted to assess the effects of harvest frequency on forage yield and quality of 2 improved cultivars (ILRI-6984 and var. DzF-552) of alfalfa (Medicago sativa L.) in Western Dembia district over 20 months during 2017 and 2018. Four harvest frequencies (every 30, 40, 50 and 60 days) were compared in a randomized complete block design (RCBD) with 4 replications. The experiment was laid down in a randomized complete block design (RCBD) in factorial arrangement with four replications. To assess their production potential plant height (cm), number of branches per plant, fresh biomass yield (t ha−1) and dry matter yield (t ha−1) of the forge and its nutrient content were recorded. The data collected was subjected to analysis of variance (ANOVA) by using the general linear model (GLM) procedure in Statistical Analysis System (SAS) (2003) version 9.1. Results The results revealed that highest forage dry matter yield was recorded for variety ILRI-6984 harvested every 40 days (26.8 t DM ha−1) and for var. DzF-552 when harvested every 60 days (24.1 t DM ha−1) (P<0.001). While crude protein concentration tended to decline as age at harvest increased, there was little consistency in the pattern. Crude protein yields were also inconsistent across treatments but ILRI-6984 harvested every 40 days produced the highest yields (6.5 t ha−1) (P<0.001). Conclusion These preliminary findings need to be confirmed under field conditions on a large scale along with longer-term studies to examine the longevity of the stands at these harvest frequencies. Irregular harvesting based on stage of maturity should be compared with fixed inter-harvest intervals.

Drying Efficiency

Balances of energy, carbon, and nitrogen were measured with fresh herbage cut at 28 days' regrowth, and with hay made from it. Measurements were made on four wether sheep at fasting and at four levels of feeding. The herbage contained paspalum grass and white clover in proportions ranging from 0.6 : 1 to 1.2 : 1, with dry matter between 11 and 17%. It contained (dry matter basis) : 10% ash, 3% soluble sugars, 25% cellulose, 23% crude protein, and 9% lignin; crude fibre was 22% and nitrogen-free extractives 42%. The hay had the same composition. Digestibility of organic matter was 75% for the fresh material and 73% for the hay; digestible energy values were 73 and 70% respectively. The difference between fresh herbage and hay was due entirely to a decrease in the digestibility of protein, from 82% to 73%, in drying. Efficiency of utilization of digested protein was not affected. Digestibility of both materials decreased by 2 to 4 units between the lowest and highest feeding levels. One other difference was found, viz. the ratio methane production/kcal digestible energy was 1–2% greater with the hay. Metabolizable energy was 82–84% of digestible energy for both materials. Heat production bore a linear relation to metabolizable energy above maintenance. Net availability of metabolizable energy was 75% between fasting and maintenance, and 52% above maintenance, for both the fresh and dry food. These quantities were predictable to within 8% from metabolizable energy or fibre digestibility; the normally used starch equivalent factors underestimated the correct values by some 25%.

Refined nutrient delivery systems are important for environmentally friendly production of cut flowers in both soil and hydroponic culture. They have to be closely orientated at the actual nutrient demand. To solve current problems, express analysis and nutrient uptake models have been developed in horticulture. However, the necessity of relatively laborious analysis or estimation of model input parameters have prevented their commercial use up to now. For this reason, we studied relationships between easily determinable parameters of plant biomass structure as shoot height, plant density and dry matter production as well as amount of nitrogen removal of hydroponically grown year-round cut chrysanthemums. In four experiments (planting dates 5.11.91; 25.3.92; 4.1.93; 1.7.93) with cultivar `Puma white' and a fixed plant density of 64 m2, shoots were harvested every 14 days from planting until flowering, with dry matter, internal N concentration and shoot height being measured. For each planting date, N uptake (y) was closely (r2 = 0.94; 0.93; 0.84; 0.93, respectively) related to shoot height (x) at the time of cutting and could be characterized by the equation y = a * × b. In the soilless cultivation system, dry matter concentrations of N remained constant over the whole growing period, indicating non-limiting nitrogen supply. In agreement with constant internal N concentrations, N uptake was linearly related (r2 = 0.94 to 0.99) to dry matter accumulation. It is concluded that shoot height is a useful parameter to include in a simple model of N uptake. However, in consideration of fluctuating greenhouse climate conditions needs more sophisticated approaches including processes such as water uptake and photosynthetically active radiation.

In order to establish a chemical fingerprint of vanilla diversity, thirty samples of V. planifolia J. W. Moore and V. tahitensis G. Jackson cured beans from seven producing countries were examined for their aroma and fatty acid contents. Both fatty acid and aroma compositions were found to vary between vanilla species and origins. Vanillin was found in higher amounts in V. planifolia (1.7-3.6% of dry matter) than in V. tahitensis (1.0-2.0%), and anisyl compounds were found in lower amounts in V. planifolia (0.05%) than in V. tahitensis (1.4%-2.1%). Ten common and long chain monounsaturated fatty acids (LCFA) were identified and were found to be characteristic of the vanilla origin. LCFA derived from secondary metabolites have discriminating compositions as they reach 5.9% and 15.8% of total fatty acids, respectively in V. tahitensis and V. planifolia. This study highlights the role of the curing method as vanilla cured beans of two different species cultivated in the same country were found to have quite similar fatty acid compositions.
