The researches were conducted on fields of a farm “Berezanskoe”, Korenovsk district, Krasnodar region. Size of a plot is equal to 112 sq. м, in three replications. The object of the research was F1 seeds of interlinear sunflower hybrid Fakel produced in 2020 with different positive modifications on a hybridization plot. The seed were planted in 2021 to estimate impact of the positive modifications (methods) on yield and quality seeds of the hybrid Fakel in progeny. Two sowing rates (60 and 80 thousand per a га) were used to realize fully a yield potential of the hybrid. A certain positive impact was fixed in variants with application of biological protection measures and microbiological fertilizers during plants vegetative period. Yield increase was 0.02 t per ha. Increase of oil content and oil yield of the hybrids Fakel in progeny under different positive modifications was insignificant: 0.2–0.3% and 0.01–0.02 t per ha, respectively. Application of biological protection measures and microbiological fertilizer during the vegetative period of plants on the hybridization in 2020 contributed in a profitability increase by 6% when sowing F1 seed in 2021 with sowing rate of 80 thousand seed per ha.

Mode Of Application

The effect of zinc (Zn), boron (B) and sulphur (S) on the yield and quality of groundnut in a field experiment with three levels of Zn (0, 5, 10 kg Zn ha<sup>−1</sup> as Zn-EDTA as basal), two levels of B (0 and 0.25% boric acid as foliar spray) and three levels of S (0, 25, 50 kg S ha<sup>−1</sup>as CaSO<sub>4</sub>.2H<sub>2</sub>O) in a factorial RBD were studied. Basal application of Zn @ 5 and 10 kg ha<sup><sup></sup>1</sup> caused an increase in nut yield by 3.7% and 28.3% respectively over control, whereas, application of S @ 25 and 50 kg ha<sup>−1</sup> increased the nut yield by 38.3% and 56.6% respectively over control. Conjoint application of Zn @ 10 kg ha<sup>−1</sup> and S @ 50 kg ha<sup>−1</sup> caused an increase in nut yield up to 73.4% over the control. Results, therefore, revealed that conjoint effect of S and Zn towards nut yield was more effective than that of B application. Application of Zn, S and B significantly increased their nutrient uptake in nuts. On an average, S, Zn and B uptake by groundnut ranged from 11.4 to 21.0 kg ha<sup>−1</sup>, 0.14 to 0.40 kg ha<sup>−1</sup> and 0.12 to 0.25 kg ha<sup>−1</sup>, respectively. Integrated mode of application of Zn, B and S showed a positive interaction as yield increase with their uptake in groundnut. Oil content in nuts ranged from 45.3 to 54.4%, while iodine value ranged from 97.8 to 90.5%. Application of S and Zn significantly increased the oil content, while it significantly decreased the iodine value in groundnut. So, application of micronutrients <italic>viz</italic>. Zn and B as well as S fertilization could be a useful strategy not only to increase the yield but also the quality of groundnut.

Further Development

One of the factors limiting high and qualitative yields of sunflower seeds is pests. Phytophages injure plants of the crop during the whole vegetative period causing growth and development disorders, and sometimes plants depth. Together, insects play the important role in distribution of pathogens, especially fungi from genera Alternaria, Fusarium, Rhizopus, and Puccinia, as well as bacteria. Among phytophages on sunflower, the most harmful are herbivorous bugs (class Hemiptera) of fleahopper (Miridae) and stinkbug (Pentatomidae) families. Bugs feeds on plants sap, they suck it out of the different plant organs. The basic oil crop in the Krasnodar region is sunflower. In 2021 its sowing area accounted to 442 thousand ha. Breaks of scientifically substituted cultivation technology lead to deterioration of phytosanitary state of sunflower crops by means of concentration of pathogens, including herbivorous bugs. The purpose of the research was to determine species and prevalence of bugs and their dominating species in sunflower crops in the Krasnodar region for the further development of protection measures. The result showed in the central zone of the Krasnodar region the sunflower crops are inhabited with 12 species of bugs from the families: Miridae, Pentatomidae, Alydidae and Coreidae. Prevalence of tarnished plant bug (Lygus pratensis (Linnaeus, 1758) and bishop bug (Lygus rugulipennis (Popp., 1911) was high (60 and 80%, respectively), and sloe bug (Dolycoris baccarum (Linnaeus, 1758) was maximal – 100%. A sloe bug prevailed in sunflower crops – 36.1%.

In order to obtain high, qualitative and economically profitable rape yield one needs wholesome and integrated manure, with the aim to ensure the plants' needs for nutritive components and to renovate the soil fertility as well. During 2005 - 2007 there was carried research on the increasing rates of potassic mineral fertilizers K0 - K160 against the background of nitrogen fertilizers N80 and N80+40. Using nitrogen fertilizer 80-120 kg ha-1 the obtained yield increase was remarkable indeed: 0.49-1.09 t ha-1. Increased potassium rate K80 - K160 ensured the yield growth up to 0.17–0.42 t ha-1 The highest oil content 48.22-48.89% was ensured by potassium rate K160. Optimal and economically grounded manure rate is N120P60K80 kg ha-1 with the yield level 2.50 t ha-1 and the oil outcome 1086 kg ha-1. In 2007 and 2008 there was carried research on the rates of stick matter AVENTROL (0.7 and 1.0 l ha-1), and its impact on rapeseed yield and quality. In spring rape sowings the yield increase was 0.49-0.78 t ha-1, but in winter rape sowings –0.72-1.03 t ha-1. The seed humidity, at harvest time, was diminished by 2-6 %. The content of oil in seeds increased by 0.52-1.49 %. The use of the preparation AVENTROL ensured the net income: 57,7 - 161,7 EUR ha-1.

Castor oil (Ricinus communus L.) is an important commercial product. The climatic conditions of Ukraine determine the possibility of growing the castor as an annual crop. At the Institute of Oilseeds NAAS studied castor collection. The aim of the work was the selection of the most promising samples of castor oil, combining a large yield potential in a narrow range of vertical distribution for optimal technological parameters of mechanical harvesting with a high content of oil in seeds and ricinolic acid in oil. In the experience of 2015-2016, the manifestation of morphological features of 17 castor bean samples was studied. The height of plants, individual samples among themselves differed more than twice. Long-brush samples of ЕР118, К374, М203, К159 are distinguished on the basis of the length of the brush. The shortest brush was observed in sample K1008. The length of the productive brush in the studied samples is from 10.7 to 32.9 cm. Most castor bean samples under favorable conditions form brushes of the second and higher orders. According to this parameter, samples of Ep118 and selection No. 38 with four inflorescences of the second order are of the greatest interest. The largest brushes of the second order are similar in size to the brushes of the first order were observed in the samples: К1127, К810, К153. The adaptability of harvesting castor beads requires that the brushes of the first and second order coincide in height with each other, since the harvester can take a maximum of 60 cm. For the sum of the productive brushes of the first and second orders, the greatest potential yield will be provided by samples K159 and K1127. Among the studied collection stands out the small seed sample K159 and the large seed samples - PRL41 and K80. The average oil content in the seeds of the collection was from 52 to 61.4%. Sample38 had the highest oil content. The content of ricinolic acid in the collection was from 70.9 to 82.9%. Samples were isolated: К134, К1008, PRL41, К430 with the content of ricinoleic acid more than 80%. The results of the study of all parameters make it possible to isolate valuable technological samples. Sample K1064 with a high technological potential of productivity, with a seed oil content of 57.2%, has a not very high content of ricinoleic acid of 74.3%. Sample K1127 with an oil content of 58.6%, a mass of 1000 seeds of 265 g, a high potential of productive brushes has a wide variation in the arrangement of brushes. Sample K134 with a oil content of 57.1%, ricinoleic acid content of 80.7% has small second-order brushes and can be used as a single-cysts in a thicker seeding.

Fertilization Experiments

The soybean varieties Lee, Forrest, Bragg and Dodds were studied in zinc fertilization experiments at three sites in central and north-west New South Wales. At each site foliar sprays of ZnSO47H2O were applied before flowering. At Narrabri one spray of 4 kg ha-1 gave a yield increase of 13%. At Trangie and Breeza, two sprays each of 4 kg ha-1 increased yield by 57% and 208%, respectively. Lee was the least responsive variety at each site and Dodds or Forrest the most responsive to applied zinc. Zinc fertilizer increased plant height, foliar zinc concentration, oil content (at two sites) but decreased leaf phosphorus content. Leaf concentrations of phosphorus in untreated plots were indicative of varietal sensitivity to zinc deficiency both within and between sites. The yield increases at Narrabri were obtained even though no visual symptoms were observed. Improvement of soybean yields with zinc fertilizer in seemingly healthy crops is worthy of further investigation.

SUMMARYAhipa is a legume of great interest for the production of raw materials (starch, sugar, oil and proteins) for industrial use. Its yield potential and ability to fix atmospheric N2 in association with rhizobia makes it an attractive option for low input agriculture systems. At present, it is cultivated on a very small scale as a food crop in a few South American countries. Little information is available on symbiotic N2 fixation in ahipa and no work has been performed on strain selection for inoculant production. Soils in southwest Europe are devoid of specific rhizobia able to nodulate on ahipa. Selecting rhizobia for symbiotic effectiveness from a collection led to the isolation of strains which provided greater shoot growth and N content under controlled conditions. In the field, inoculation at sowing with the selected strains increased significantly seed and tuberous root yield and seed protein content. The amount of N2 fixed, estimated by 15N natural abundance, reached 160–260 kg N ha−1. In previous work, ahipa appeared to be a promising alternative crop for the production of industrial raw materials. The results of the present study showed a yield increase in tuberous roots and seeds when applying effective rhizobia inoculants. Furthermore, a positive soil N balance was left after its cultivation making ahipa even more interesting for sustainable farming systems.

The Impact

Triggering the plant resistance induction phenomenon by chemical compounds, for example acibenzolar-S-methyl ester, has been known and described in scientific literature. Other benzothadiazole derivatives have been also described; however, their properties have not been sufficiently studied. The tested substance, N-methyl-N-methoxyamide-7-carboxybenzo(1.2.3)thiadiazole (BTHWA), is an amide derivative of benzothiadiazole, showing a stimulating effect on plant growth, apart from its plant resistance inducing activity. This article presents the impact of BTHWA, used solo and in the program with fungicides, on the strawberry plants development, fruits health, yield, and quality parameters of the crop. The results show that the combined use of BTHWA and fungicides had a positive impact on the plants health and fruit health and nutraceutical and nutritional composition of compounds when compared to the results obtained when strawberries were treated only with the BTHWA or the fungicide. As a result of BTHWA use, the partitioning of assimilates has changed, which directly translated into the results of the conducted experiments. A reduction in the respiration of the fruit during storage was also observed, possibly due to a reduced disease infestation and a lower dry matter content in the fruit. A correlation between the parameters determined during the experiment was found. The BTHWA mode of action was evidenced to be beneficial to strawberry plants and fruit.

Yield and quality performances of three jackfruit genotypes were studied at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Pahartali, Chittagong during 2013-2014. Age, growth, maturity period, yield potential and also qualitative characteristics were compared among them.  Based on overall performance with respect to bearing potential, maturity period, fruit and bulb characters, the genotypes AHPah-1 have been found promising for table purpose followed by AHPah-2 and AHPah-3. Minimum days (117) to 1st harvest were observed in AHPah-1. The number of fruits per plant was exceedingly higher (73) in AHPah-1 whereas minimum number (41) was found in AHPah-2. Maximum weight (8.40 kg) per fruit was observed in AHPah-2 and minimum was in AHPah-1(3.40 kg).  The highest single fruit length (37.25cm) was found in AHPah-2 and breadth (27.00cm) was produced by AHPah-3. Maximum number of bulbs (116) was produced in AHPah-1, whereas minimum (63.00) was in AHPah-3. Maximum weight of bulbs per fruit (4.24 kg) was produced in AHPah-2. Individual bulb weight was higher (54.42g) in AHPah -2 whereas, the lowest (16.71) was in AHPah-1. Edible portion was higher (69.27%) in AHPah-1 whereas, the lowest (53.43%) was in AHPah-3. The TSS was the highest (21.00%) in AHPah-1. The highest bulb length and breadth was found in AHPah-3. Highest seeds weight (639g) was produced in AHPah-2. Individual seed weight (8.19 g) was higher in AHPah-2. Therefore, the genotypes can be included in the variety development program after comparing with the already BARI released jackfruit variety.The Agriculturists 2016; 14(1) 107-111

Substrate-filled pots are growing systems commonly used for vegetable farming. However, few are the studies available relating them to mini-watermelon cultivation. Our study presents a growing system using substrate-filled troughs and leachate recirculation as a low-cost and less environmentally harmful soilless cultivation system for mini-watermelons. For a growing system to be viable and provide high fruit yield and quality, several aspects must be studied, including substrate physical properties and reuse potential in successive crops, besides plant management-related aspects. Therefore, our goal was to evaluate the effects of a trough system and substrate reuse on changes in the properties of raw rice husk and on fruit yield and quality for mini-watermelons at different stem training. To this purpose, two trials were conducted using nutrient solution recirculation systems. In the first, we evaluated the effects of pot and trough systems. In the second, first- and second-use substrates were compared in the trough system. In both trials, one and two-stem training systems were analyzed. The results of the first trial show that the trough system had a greater positive impact on substrate water holding capacity (WHC), which increased from 7.9 to 15.6%, while the pots increased substrate WHC only to 11.2%. However, both systems neither affected fruit yield (8 kg/m² on average) nor fruit quality. The two-stem training promoted higher fruit yields (4.2 kg/plant) and contents of total soluble solids - TSS (11.4 °Brix) but did not affect average fruit weight. Moreover, the one-stem training provided higher fruit number (7.3 fruits/m²) and fruit yield (9.7 kg/m²). In the second trial, the reused substrate showed a higher WHC (12.4%) than the one used for the first time (9.9%). The reused substrate also provided better results in terms of fruit yield and quality (5.9 fruits/m², 5.3 kg/m², and 10.5o Brix). In the second trial, two-stem training also increased average fruit weight, and hence yields per plant. Nevertheless, the stem number did not affect fruit number per plant, fruit yield per square meter, and fruit quality.

Caraway has very low competitive ability against most of weed species. Therefore, it is important to choose a suitable herbicide control, especially at biennial caraway. The experiments with the herbicides applied in caraway were found in pure growth, with variety Kepron (with standard length of ve­ge­ta­ti­ve period). The aim of the trials was to find out the differences at achenes yiled and essential oil content after the treatment by the various herbicides, applied preemergently. Also, the selective ac­ti­vi­ty of individual herbicides was tested, including the different doses. The herbicides used in the ex­pe­ri­ments had enough level of selektivity on the plants of caraway. They had a positive effect on the yiled comparing to non-treated control variant in all observed years. There was no statistically significant difference in essential oil kontent between the treated variants and non-treated control. On the basis of these results, the most suitable herbicide was chosen for the „minor“ registration for caraway.
