Abstract

This research aimed to assess the effect of Naphthalene Acetic Acid (NAA) and nitrogen fertilizer on the growth of sugarcane (Saccharum officinarum L.) bud chips. The research was conducted using a 4 x 4 factorial design with the basis of a completely randomized design (CRD) of 3 replications. The first factor was the concentration of NAA which consisted of 0 ppm (without NAA), 50 ppm, 100 ppm, and 150 ppm. The second factor was the dose of nitrogen fertilizer which consisted of a dose of 45 kgN/ha, 90 kg N/ha, 135 kg N/ha, and 180 kg N/ha. The growth parameters observed included plant height, number of leaves, tillers, root dry weight, and shoot dry weight. The data were analyzed by analysis of variance and continued with Duncan’s test (Duncan’s Multiple Range Test) at a 5% level. The results showed that the application of NAA could not increase the growth of sugarcane bud chips on all parameters. Application of nitrogen fertilizer at a dose of 45 kg N/ha could increase plant height growth, number of leaves, root dry weight, and shoot dry weight. Nitrogen fertilizer with a dose of 180 kg N/ha reduced the growth of sugarcane bud chips. The higher dose of nitrogen fertilizer inhibited the growth of sugarcane bud chips.

Abstract

One of phosphate (P) fertilizer i.e. SP-36 is expensive and can be obtained by rock phosphate (RP). Rock phosphate combined with Vesicular Arbuscular Mycorrhizal fungus (VAM) could increase Pavailability. VAM consists of many species, so it is necessary to test the role of VAM species on cherry tomato plant. This study aims to examine the effect of VAM species and phosphate fertilization to improve cherry tomato production. The research use a Completely Randomized Design (CRD) which consisted of two factors with three replications. The first factor is the phosphate fertilization (P0= without P fertilizer, P1= SP-36, P2= rock phosphate) and the second factor is VAM species (M0= control without mycorrhizae, M1= Glomus etunicatum, M2= Glomus fasciculatum, M3= double inoculation of G. etunicatum and G. fasciculatum). The results show that mycorrhizae inoculation increases plant height, fruit number, fruit weight and accelerates flowering age compared to without inoculation. BP fertilization increases fruit weight. BP+CMA produces number of fruit equivalent to SP-36+CMA. BP+G. etunicatum treatment significantly increases fruit weight compared to SP-36+G. etunicatum. G. etunicatum inoculation gives the highest fruit weight compared to other inoculation.

Abstract

Pakcoy is a viable horticultural plant. High consumer demand, but the national pakcoy production is still low. This study aimed to examine the effect of various compost doses and PGPR doses on the growth and yield of pakcoy plants. This study used a 5x4 factorial RAL with 3 replications. The first factor is compost dosage (K) consisting of K0 = 0 kgN/ha compost, K1 = 138 kgN/ha compost, K2 = 69 kgN/ha compost, and K3 = 138 kgN/ha compost, K4 = 207 kgN/ha compost. The second factor is the PGPR dose (P) consisting of P0 = 0 ml/l water, P1 = 5 ml/l water, P2 = 10 ml/l water, and P3 = 15 ml/l water. The results showed that offering compost as much as 207 kgN/ha increased the growth and yield of pakcoy plants compared to giving 138 kgN/ha of inorganic fertilizer. The increase in the PGPR dose that was applied 2 times at planting and 14 days after planting (DAT) of 200 ml did not significantly increase the growth and yield of pakcoy plants.
