A STUDY ON THE EFFECT OF PLANT DENSITY AND DOSAGE OF MICROBIAL - ORGANIC FERTILIZER ON THE GROWTH, DEVELOPMENT AND YIELD OF F1 NHP 69 VARIETY OF CABBAGE

Abstract

Study the considered the effect of plant density and dosage of microbial-organic fertilizer
on the growth, development and Yield of F1 NHP 69 variety cabbage, the experiment was
conducted at Hoang Hoa district, Thanh Hoa province, The experiment was designed in SplitPlot with 12 treatments and 3 replicates, the experiment combined three levels of planting
density and four levels of dosages of microbial organic fertilizer, three planting densities were
M1: 30,000 plants/ha; M2: 36,000 plants/ha and M3: 45,000 plants/ha; four dosage levels of
microbiological fertilizer (H0: 500 kg/ha, H1: 1,000 kg/ha, H2: 1,500 kg/ha, H3: 2,000 kg/ha),
The study result showed that the planting density and dose of microbial organic fertilizer could
efficiently promote the development and yield capacity of NHP 69 variety of cabbage, The
treatment of M2H2 (planting density of 41.000 plants/ha and application of 1.500 kg/ ha)
obtained the best growth, development and yields, The outer stem height was 18.2 cm, the highest
canopy diameter archieved 70.8cm, the number of outer leaves (28.9 lá) and the highest yield
obtained the average of 49.7 tons/ha. However, the treatment M2H2 obtained the highest benefit
because the payments of fertilizer was lower than the treatment M2H3. Therefore, Hoang Hoa
district should choose the planting density of 36,000 plants/ha and 1,500kg/ha of microbial -
organic fertilizer for cultivating F1 NHP 69 variety cabbage
