Abstract

Optimization of production rice plants can be achieved if the needs of macro and micro nutrients essential plant fulfilled. To achieve optimal rice yield can be done by proper fertilization based on the type, characteristics and nutrient content of fertilizers applied. Alternative to increasing rice yield can be done by applying biofertilizer in reducing the use of inorganic fertilizers. This experiment aims to determine the effect of Solid Biofertilizer (SBF) on nutrient uptake, growth, and yield and yield components of rice paddy fields. This research was carried out on the planting medium Inceptisols at Jatinangor used a Randomized Completely Block Design (RCBD) with 10 treatment combinations which replicated 3 times. The results showed that a dose of 1 NPK, combined with SBF ranging from ¼ dose, dose ½, ¾ and 1-dose showed gradual improvement to the uptake of N and P as well as yield and yield components of paddy.Keywords: Solid Biofertilizer, NPK Fertilizer, Paddy Yield

Abstract

The aims of the research were to study the growth of plants in the nursery and look for the optimum concentration of H2SO4 solution at certain storage duration that gives the highest dry plant weight in the nursery. Experiments were conducted in the seed laboratory and in the nursery of Faculty of Agriculture, Winaya Mukti University using randomized block design factorial with 2 factors. The first factor was the time and concentration of sulfuric acid solution i.e. Soaking 6 minutes in H2SO4 0.25%, 0.50%, 0.75% and 1.0%. The second factor was seed storage duration i.e. without being stored, 1, 2, and 3 months. The data was analized using linear quadratic regression method. The experimental results showed that there was interaction between seed storage time and concentration of sulfuric acid solution on leaf area and plant dry weight. The treatment without storage time and concentration of 0.75% sulfuric acid solution gave the best effect compared to other treatments. Zero minutes of storage followed with sulfuric acid concentration as much as 0.67% gave the highest dry plant weight of 28.193 g.Key words: Jarak seed, Concentration H2SO4, Seed saving time
