| dc.description.abstract | The objectives of the study (1) evaluate the availability of nutrients N P
and K and the needs of chili plants on intensified land based on the calculation of
nutrient equilibrium N, P, K on chili intensive land, (2) determine the next
fertilization recommendation based on nutrient balance improvement on chili
intensive land. The research was conducted on intensive land of curly red chili
plants of CV partner farmers. Brillian Jaya Mandiri in Jember, Bondowoso, and
Banyuwangi. Laboratory analysis aims to determine the residual residue in the
soil and the absorption of nutrients N, P, K plants and fruits. Based on the results
of the study, it was concluded that the availability of nutrients N in the field of
jember chili was moderate; N medium Bondowoso chili field; N high
Banyuwangi chili field. The P element of the jember chili field is very high; P
Bondowoso chili land is high, P Banyuwangi chili field is very high. Element K of
Jember chili field is medium, K of Bondowoso chili field is low, K of
Banyuwangi chili field is low. The nutrient balance of N, P, K in intensive land of
chili plants is based on the calculation of the nutrient balance of the three regions
as follows, the Jember region is N -257.7 kg N/ha, P +74.4 kg P/ha, K -7.3 kg K/ha.
The value of nutrient balance N, P, K in Bondowoso area is N-298.5 kg N/ha, P +74.1
kg P/ha, K +42.7 kg K/ha. The nutrient balance of the Banyuwangi region is N -144.5
kg N/ha, P +74.9 kg P/ha, K +21.3 kg K/ha. The positive value of the nutrient balance
N, P, K indicates equilibrium. The negative value of the nutrient balance N, P, K is
unbalanced. Fertilization recommendations on intensive land of chili plants based on
the calculation of nutrient balances N, P, K show negative values in nutrients N and K
specifically for the Jember region, so that in the next planting season it is necessary to
fertilize the addition of Urea fertilizer of 144.3 kg N / ha and added KNO3 fertilizer of
1.5 kg K / ha for the Jember region, in the Bondowoso region urea fertilizer was added
by 167.17 kg N/ha and the Banyuwangi region added urea fertilizer of 80.92 kg N/ha. | en_US |
