The objective of this research was to investigate the effectiveness of combination of bio-slurry fertilizer and NPK fertilizer on the growth and production of two varieties of rice. The experiment was assigned in a completely randomized design of factorial pattern. The first factor was the combination of bio-slurry and NPK fertilizer that consisted of P0 = no added fertilizer (control) 0 ton/ha, P1 = NPK fertilizer 550 kg/ha (165 kg N, 33 kg P, 45 kg K); P2 = bio-slurryfertilizer 2.3 tons/ha (45 kg N, 14 kg P, 23 kg K) and NPK fertilizer 400 kg/ha (120 kg N, 24 kg P, 32 kg K); P3 = bio-slurryfertilizer 4.6 tons/ha (90 kg N, 28 kg P, 46 kg K) and NPK fertilizer 250 kg/ha (75 kg N, 15 kg P, 20 kg K); P4 = bio-slurry fertilizer 5.9 tons/ha (115 kg N, 36 kg P, 59 kg K) and NPK fertilizer 100 kg/ha (30 kg N, 6 kg P, 8 kg K); and P5 = bio-slurryfertilizer 8.5 tons/ha (165 kg N, 52 kg P, 85 kg K). The second factor was varieties of rice that consisted of V1 : IR-64 and V2 : Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1.000 grains, and rice production. Data were analyzed using ANOVA and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the combination of bio-slurry fertilizer and NPK fertilizer were significantlyaffect (p <0.05)all observation parameters, while varieties of wetland rice did not show significant effect on all observation parameters (p<0.05). The application of bio-slurry fertilizer in single treatment or in either combination with NPK fertilizer had the same result with the treatment of NPK fertilizer on the growth and yield of rice.

Fertilization is one of the factors that influence the growth and production of sticky maize. This study examined the effect of organic-NP enriched manure on the growth and yield of sticky maize. The study used a Randomized Complete Block Design (RCBD) with four replicates. The treatments are P0 (ZA + TSP), P1 (cow manure + ZA + TSP), P2 (goat manure + ZA + TSP), P3 (poultry manure+ ZA + TSP), P4 (cow manure + Gliricidia sepium + BP), P5 (goat manure + Gliricidia sepium + BP), P6 (poultry manure + Gliricidia sepium + BP). The parameters observed were plant height, number of leaves, chlorophyll content, cobs length, and cobs diameter. The results showed that the number of leaves, chlorophyll content in the generative phase, and cobs diameter in treatment P1 (cow manure + ZA + TSP) is equivalent to P4 (cow manure + Gliricidia sepium + BP), P2 (goat manure + ZA + TSP) is equivalent to P5 (goat manure + Gliricidia sepium + BP), and P3 (poultry manure+ ZA + TSP) is equivalent to P6 (poultry manure + Gliricidia sepium + BP). The cobs length in treatment P3 is significantly higher compared to P6. All treatments have no effect on plant height and chlorophyll content in the vegetative phase.
