EFFECT OF ORGANIC FERTILIZER ORGALIFE ON SOME YIELD AND QUALITY PROPERTIES OF RICE (ORYZA SATIVA L.)

Abstract

This study presents the effect of ecological fertilizer Orgalife on some yield and quality properties of two rice varieties, San Andrea and Opale, during the time period 2020-2021. In a field experiment arranged in Zade method, three treatments were studied: control (350kg/ha NPK) as a basic fertilizer and 200kg/ha Urea (46% N) and two variants with Orgalife foliar application in dosage: 20L/ha - variant 1 and dosage of 20L+20L/ha - variant 2. In variant 2, Orgalife was applied twice in an interval of 10 days. Biological, grain and straw yield, number of productive tillers/m², 1000 kernel weight of paddy and whole grains white rice and milling fractions were examined. Results were analyzed with ANOVA and LSD test. Opale’s variant 2 presented significantly the highest average in both years for biological (18575kg/ha), grain (11458kg/ha) and straw yield (7115kg/ha) compared to the control lowest average. For San Andrea, significant differences were noticed for grain yield in variant 2 (8883.33kg/ha) compared to the control (7350kg/ha). Opale’s variant 2 determines the highest statistically significant average (612.17) of productive tillers/m² for both years compared to control. For 1000 kernel weight of whole grain white rice, the averages for Opale’s variant 2 (22.73 g) were on pair with the control (22.42 g), as well as the total milled rice. Opale showed approximately the same average values about the total milled rice examined in both years regardless of the treatments (69.30% variant 1, 70.05% variant 2 and 71.57% control). The results about whole grain white rice vary from 45.73% (control) to 46.75% (variant 2).
