[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city. A field experiment was arranged in a randomized complete block design (RCBD) with 3 replications for alloting two factorial treatments structure, namely rates of fruit thinning (no fruit thinning, thinned to one fruit /plant, thinned to two fruits/plant, and thinned to three fruits/plant) and rates of NPK fertilizer application (400, 600, and 800 kg/ha) on rhe experimental plots. The results showed that fruit thinnings resulted no increament in crop productivity, but the fruit quality was improved as fewer number of fruits were retained on each plant. The NPK fertilizer at 400, 600, and 800 kg/ha were not able to increase the productivity of cantaloupe  and the quality of the  produced fruit when  the application were made only at planting and 23 days after planting.

Negative Effect

Among the various abiotic stresses, drought is the major factor limiting crop productivity worldwide. Citrus has been recognized as a fruit tree crop group of great importance to the global agricultural sector since there are 140 citrus-producing countries worldwide. The majority of citrus-producing areas are subjected to dry and hot summer weather, limited availability of water resources with parallel low-quality irrigation water due to increased salinity regimes. Citrus trees are generally classified as “salt-intolerant” with high water needs, especially during summer. Water scarcity negatively affects plant growth and impairs cell metabolism, affecting the overall tree growth and the quality of produced fruit. Key factors that overall attempt to sustain and withstand the negative effect of salinity and drought stress are the extensive use of rootstocks in citriculture as well as the appropriate agronomical and irrigation practices applied. This review paper emphasizes and summarizes the crucial role of the above factors in the sustainability of citriculture.

Growth performance, carcass characteristics and meat quality of European and British crossbred (EBC; no Wagyu genetics; 28 heifers and 30 steers) cattle were compared with crossbred cattle with 75% Wagyu genetics (WC; seven heifers and 14 steers) to determine the influence of Wagyu genetics on marbling grade of beef cattle fed barley-based diets in a factorial design experiment. Weaned calves (250 d average age) were fed, one of two diets (diet 1, 35% barley grain; diet 2, 40% hay cubes on DM basis, with barley silage, protein and vitamin/mineral premix) for 84 d and then fed diet 1 until they weighed 394 to 432 kg. All cattle were finished on an 80% (DM basis) rolled barley diet and slaughtered. Carcasses were graded and samples procured for meat quality and Warner–Bratzler shear force determination. Number of days on backgrounding diets to arrive at target weight (380 kg) was greater (P < 0.05) for the WC cattle, owing to relatively lower ADG, but days on the finishing diet were fewer for these cattle, compared with EBC cattle. Warm carcass yield (dressing percent) was greater (P < 0.05), but backfat depth was lower (P < 0.05) for WC cattle relative to that of EBC cattle, yet proportion of lean meat yield was similar. Eighty three percent of WC cattle carcasses had Canada AAA (small or more) marbling grade compared with 13% for EBC cattle carcasses. Mean shear force of meat samples from EBC and WC cattle was 4.2 and 3.8 kg, respectively. Results indicated that the extent of carcass marbling can be increased by incorporating Wagyu genetics but age at slaughter of WC cattle was 19 d greater than that of EBC cattle and carcass size was reduced.

Chemical Procedure

It is possible to decompose starch into monosaccharides by the method of acid starch hydrolysis. By applying appropriate chemical procedure, a main solution is obtained, from which aliquots are taken after filtration to determine of the present glucose according to Luff-Shoorlu method. The analysed potatoes of cv. Desiree, grown on various sites in Serbia, have starch content that corresponds to available literature data. The highest starch content is found in potatoes from Ivanjica and Novi Pazar, i.e. from the areas where climate factors, air temperature, and land relief are favourable for potato growing. Lower starch contents are found in potatoes grown in flat areas with warmer climate and drier periods. Those are sites in PKB-Belgrade, Smederevo, Dobanovci and Mrcajevci areas, where the values obtained by experimental procedure are very similar. The lowest starch content is found in potatoes from Belegis and Guca sites, where starch content is lower than normal from literature values, which may be explained by some special causes (climate, location, irrigation). On the basis of heavy metal contents in potato samples, it may be concluded that potatoes originating from sites famous for potato production are contaminated with Cd the content of which exceeds concentrations permitted by regulations. The presence of Cd in potato samples may also be explained by the application of phosphate fertilizers in higher (or recommended) rates. However, the soil itself should also be investigated, especially concerning the content of Cd and pH value. Thus, the influence of the soil itself should be established compared to fertilizer application in the current season. Presence of Cd in potatoes, on the other hand, is highly unfavourable because it prevents its utilization in nutrition, but also as a raw material for further processing of products based on potatoes: chips, etc. Also, Cd presence in foods is strictly controlled by EU, which prevents possible export of products based on potatoes containing Cd. Analyses of lindane and bensultap (Bancol) pesticides indicate that they are not within critical values, nor in such quantities to affect human health, so, from this aspect, the analysed potato samples from all sites are absolutely suitable for consumation.

An experiment on the effect of Osmocote fertilizers on growth and nutrient status of <em>Carex buchananii</em> was conducted in the years 2008–2009. <em>Carex buchananii</em> is a dense-tufted sedge growing up to 60 cm in height, with very narrow, stiff, red, copper and olive colored leaves throughout the season. Plants were grown in a greenhouse in pots with peat substrate for 18 weeks. The differentiating factors included the type of fertilizer, i.e. Exact Standard 16:11:11 and Osmocote Exact High Start 11:11:19, and fertilizer application rates of 2 and 4 g dm<sup>−3</sup>, the phase of growth, i.e. 1 to 9 weeks and 9 to 18 weeks of culture. The greatest increment in the tuft circumference of <em>C. buchananii</em> was recorded in the first 9 weeks of culture, while that of the fresh weight of aboveground parts – in the period from 9 to 18 weeks. The application of Osmocote Exact High Start at 4 g dm<sup>−3</sup> in the culture of <em>C. buchananii</em> resulted in the production of the desired quality of the plants with a greater tuft circumference and shorter leaves. It was shown that best quality plants contained in their aboveground parts the following amounts of macronutrients and sodium (g kg<sup>−1</sup>): N – 18.9, P – 3.5, K – 37.2, Ca – 5.8, Mg – 3.0, and Na – 0.3.

Wood Residues

Intensive potato cropping has been reported as a major cause of degradation of sandy soils. Wood residues from tree clipping applied to soils can substitute for crop residues to maintain adequate organic matter levels and crop productivity. However, this ligneous material presents a C:N ratio varying from 50 to 175 and, when applied in large quantities, may induce N immobilization at the expense of the crop. The objectives of this study were to quantify the importance of this N immobilization following addition of residues and its effect on yield and quality of potato crops. Fresh or humified residues (50 t ha−1) were applied to the soil and incorporated. The third treatment received no residue. Each treatment was subdivided into subtreatments which received either 0, 150, 200 or 250 kg N ha−1. P, K, Mg and S were applied at the same rate on all treatments. Following the application of wood residues in 1987, 46 kg N ha−1 were immobilized in amended plots. N recovery from fertilizer was 51%. To obtain comparable yields of similar quality to those measured on unamended plots, an additional 1.9 kg N t−1 residues added or 100 kg N ha−1 were required. In 1988, N immobilization was considerably reduced; yield and quality of potato tubers in plots that received wood residues the previous year were comparable to those of the unamended plots with appropriate fertilization. Water retention was significantly improved in plots that received wood residues. Partial decomposition of the residues for 1 yr prior to application on the soil did not significantly improve plant growth compared to fresh residues.

Two Parameters

SUMMARYThe effect of level of N fertilizer on the composition, yield and quality of 21 crops was studied in experiments on adjacent sites of the same field to aid in the development of fertilizer recommendations.Yield of each of the crops first increased and then either remained the same or declined with further increases of N fertilizer. Interpretation by means of a simple model enabled response curves to be characterized by two parameters; one representing the beneficial component of the response and the other the detrimental component. Both varied greatly from crop to crop.The magnitude of the beneficial component of the response of most non-leguminous crops was largely determined by the potential demand of the crop for nitrogen; the exceptions were some root crops which responded less than would be expected on this basis. The adverse component was serious with root crops and those crops that are in the soil for only a short period. High levels of N increased the ratio of foliage to storage root dry weights even when total dry matter was unaffected. The changes were associated with a considerable increase in the % N in the dry matter of the roots.When crops were grown with their optimum levels of N fertilizer a simple linear. relationship between the mean %N in the dry matter and the total weight of dry matter per unit area covered all crops. Simple relationships also existed between total dry matter of non-leguminous crops and (a) the amount of N taken up by the crop from unfertilized soil, (b) the recovery of added fertilizer by the crop and (c) the beneficial component of the response of crops harvested before October.Percentage N in the dry matter at harvest was not a sensitive indicator of the extent to which plant growth was restricted by lack of nitrogen; a difference of 0·1% N in the plant material was associated with a 10% increase in yield.N fertilizer levels influenced the % dry matter and the incidence of crop disorders such as rotten roots and tissue discoloration, but the effects were seldom appreciable with practicable levels of fertilizer application.
