Research on the Influence of Density and Fertilization Concerning the Sunflower (Helianthus annuus) Hibrids Quality on the Cambic Chernozem from Fundulea

SUMMARY

Research was done in an experimental field of NARDI Fundulea, not irrigated variant, the main purpose being the influence of density and fertilization on the production quality of three sunflower hybrids (a1 - Performer; a2 - KWS Barolo RO; a3 - PR64A89). Concerning the plant density, they were used two variants, respectively c1 of 50,000 plants/ha, and c2 of 60,000 plants/ha. Other significant factors were the climate and soil conditions. In the area, the experimental conditions are characterized by the transition from steppe to forest steppe that allows especially the formation of cambic chernozem category soil. The quality data processing was performed following the analysis in the laboratory of sunflower seeds, yielded as samples of 750 g. After removing the impurities they have been determined 1000GrainWeight, hl mass, and the seeds oil content in the conditions of 2012 year climate.

Strawberry is a commercial fruit. It’s Growth and quality is influenced by soil condition, climate, and its self. Irrigation influences soil characteristic, such as: physical, chemical, and microbiological than influence an environment of its growth. this research used drip irrigation method with debit variation and organic matter composition. RCBD was used in this research. Variation of irrigation debit and organic matter composition are the independent variables, whereas dependent variables are C-Organic, N-available, characteristic of soil, and quality of strawberry fruit. Variation of debit irrigation did not significant influence to C-Organic, whereas organic matter composition had significant influence to C-Organic in 63th, 84th, and 105th day of planting. The highest C-Organic content on D3P3 treatment that is 17.92% and the lowest on D2P2 treatment that is 5.19%. Debit of irrigation influence to N-available content in 105th day of planting. The highest N-available content in D3P1 treatment that is 0.88 ppm, whereas the lowest N-available content in D2P3 treatment that is 0.67 ppm. Result of analysis, debit irrigation had significant influence and could increase fruit weight and reduction sugar-content. Organic matter composition had significant influence to increase fruit weight, vitamin C, total of soluble-solid, and reduction sugar-content. Combination of irrigation debit and organic matter composition had significant influence to fruit weight. In the treatment, debit ofirrigation that make good influence to fruit quality is 300 ml/day/polybag and 1:2 ratio of organic matter composition.Keywords: drip irrigation, organic matter, strawberryDiterima: 16 September 2008; Disetujui: 25 Pebruari 2009
