Experiments were performed to characterize the response of peanut local cultivars from Banten to soil water availability decreased during the reproductive phase. The experiments used factorial randomized block design with three replications of two factors. The first factor was the soil water availability consists of three levels (100%, 75%, and 50%). The second factor was the peanut local cultivars from Banten consists of four levels (local cultivars of Cikeusal, Petir, Anyer, and Cisoka). The results showed a similar general pattern that was the decreasing soil water availability resulting in the decreasing amount of flowers and pod number of peanut local cultivars from Banten. Flowers appear began to plant at 24 and ending at 46 days after planting with a period of at most appear at the age of 26 up to 36 DAP. Four peanut local cultivars from Banten showed no difference in tolerance to the declining of soil water availability. Number of flowers and peanut pods begin to decrease when soil water availability as as much as 75%. Keywords: Flower, Local cultivars, Peanuts, Soil water availability, Pod number

Fruit size is an important character in determining the quality of papaya fruit. Domestic consumers prefer small or medium size papaya fruit, while for the desirable fruit slices are large one. Assembly papaya varieties based on fruit size can be done through conventional breeding. The objectives of this study were to determine the effects of heterosis and gene action on the fruit size character of the papaya hybrid. The research was conducted at KP. Sumani Tropical Fruit Research Institute, Solok, West Sumatra in 2010-2011. This research used a randomized block design with 25 treatments (20 hybrids and five elders papaya) and repeated three times. The results showed that in general the heterosis effect on fruit size (weight, length and girth of the fruit) was found below 50%. Heterosis effect can decrease and increase the size of the fruit because the value is negative and positive. The negative excess of dominant gene action resulting in smaller sizes of F1 than the average of both parents or youngest parents. Therefore, crosssing BT3 x BT2 had the smallest fruit size. Positive excess of dominant gene action i.e crossing BT1 x D, BT4 x BT1 and D x BT3 resulted in bigger fruit size than two parents. Keywords: Gene action, Heterosis, Hybrid, Papaya

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
