The young cob of waxy corn is consumed like sweet corn, however, waxy corn is glutinous and delicious because due to the low content of amylose which is less than 10.0%. The yield of waxy corn is commonly low around 2.0-3.0 t/ha and early maturity which is harvested in 85 days. Therefore, the yield has been improved through the intra population improvement S1 families selection. Nine genotypes were evaluated to select good population adapted under lowland condition in central corn production. The aims of reseach were to find of population (g) of maize waxy corn which good stability and average yieled was more than average in all locations. Randomized complete block design with four replications was conducted in five district (e) of central corn production (Maros, Polman, Manado, Probolinggo, Pakanbaru) on dry and wet season (s) under lowland in 2011. The spacing 75x20 cm, one plant per hill, genotypes was planted in 5.0 m lenght in four rows, and fertilized with Urea, SP36 and KCL (300-200-100) kg/ha. The yield stability was founded significant of interaction genotype x environment x season (g x e x s) and yield be increase if good environment also would increase (b>1.0) and average yield>total average in evt. The result showed that population PMS-D (Pulut Muneng Synthetics with grain texture of dent) be founded of yield 5.56 t/ha and 5.82 t/ha under wet and dry season or more than 17.0% than local check varieties (PH). Simple correlatin of yield PMS-D were significant on weight of seeds, ears weight, number of seeds in ear, and 1000 weight of seeds. There are not significant correlation of yield with amylase, carbo hydrate, protein and fat. The characterâ€™s of population was score one on plant aspect, husk cover, and ear aspect. The position of ear was middle of plant height, flowering in 45 days. The best population of PMS-D would be promising as new candidate of open pollinated variety and could increase farmers income than local waxy variety.

Nitrogen is the main macro nutrients that are needed rice crops, without it the yield of rice equal with rice without fertilizers. Fertilization without taking into consideration characteristics of the soilÂ caused changes in soil nutrient imbalances. Response of plant to nitrogen fertilization changed the imbalanceÂ nutrient in the soil, so the evaluation of urea fertilization need to be done. The aim of this paper is to evaluate the urea fertilization for rice in rainfed areas. The study was conducted in six locationsÂ Andong, Jakenan, Cibeber, Gabus, Panimbang and Sukadana during the dry season in 2015 and 2016. Urea fertilization is part of the N, P, K fertilizer experiment which carried out with aÂ randomized complete block design with four levels of N fertilizer dose. The dose level of N fertilizer were 0, 200, 300, and 400 kg urea/ha, which is repeated three times. In addition to urea as treatment, each plot of treatment added 125 kg SP-36 and 100 kg KCl per ha. The results showed that the majority of the rainfed areas containing N low. N fertilizer significant increased of plant height between 12.9 â€“ 32.4 cm, number of tillers from 3.3 to 8.6 stems, weight of dried grain harvest from 1.93 â€“ 5.00 t/ha, weight of grain dry milled 1.52-2.59 t/ha, and dry straw weight increase between 2.29 to 3.17 t/ha. The optimum dose of urea fertilizer for rice rainfed areas ranged between 200-300 kg urea/ha. Dose of fertilizer based on productivity of the rice is still relevant is used as a basis for the create of urea fertilizer recommendation.

The low production of hybrid rice seed is influenced by the syncronized of flowering time between CMS and restorer. One of several ways to syncronize both two CMS and restorer was use gibberellins. Gibberellins as growth regulator worked by triggered plant growth and flowering. The objective of this research was to obtain the optimal concentration of GA3 to support theÂ increase hibryd rice seed production. The experiment was arranged in a split plot design based on randomized complete block design. The first factor was three hybrid rice varieties (V) i.e. V1 Hipa-8 (A1 and PK91), V2 Hipa-14 (A7 and PK92) and V3 Jatim-3 (A6 and PK88) belong to the Center for Rice Research (BB Padi) as the main plot and the second factor was four level concentrations of gibberellins (GA3) i.e. G0 (without GA3), G1 (GA3 150 ppm) G2 (GA3 200 ppm) and G3 (GA3 250 ppm) as a subplot. The treatment wasÂ performed by spraying GA3 with spray volume of one liter per a plot on the female and male parent. The results of experiment showed that concentrations of GA3 treatment significantly increased plant height, angle of floret opening and decreased number of empty spikelets. The treatment interaction of GA3 concentration and variety significantly effected on percentage of increasing plant height and productivity. The highest productivity was rice hibryd ofÂ A7 (Hipa-14) of 1 000 kg/ha with application of 200 ppm GA3.

Leaf-eating caterpillars are important soybean pests that widely distributed from tropical to sub-tropical regions under wet and humid conditions. In Indonesia, these caterpillars attacked 1,316 hectares of soybean crops in year 2002, and it increased to 2,902 hectares of soybean crops in year 2006. Therefore, the effective pest control needs to be identified. The experiment on controlling leaf eating caterpillars used bio-insecticides of NPV and SBM, and resistant varieties was conducted at Kendalpayak Experimental Farm of Indonesia Legumes and Tuber Crops Research Institute in dry season of 2016. A strip plot design with three replications was applied, where the vertical factor was varieties i.e. (1) Wilis, (2) Degra 1, and (3) G100H, and types of insecticide as horizontal factors i.e. (1) without insecticides, (2) 50 g of neem-seed flour (SBM) in 1 litre of water, (3) 2 g of SlNPV in 1 litre of water, (4) SBM + NPV, and (5) chemical insecticide. The results indicated that SlNPV was effectively suppressed the population of caterpillars as shown by its lowest numbers. Also, the combination treatment of SBM + NPV had better suppression than that of chemical insecticide. The role of Degra 1 variety, which is a resistant variety to leaf eating caterpillar, was very important in suppressing the damage rate of the plants as pointed out by 26% reduction of damage rate compared to that of Wilis variety (the susceptible variety to leaf eating caterpillars). The effectiveness of leaf eating caterpillars control could be enhanced by combining the resistant variety of Degra 1 with NPV bio-insecticide. This application obtained 35% of suppression rate which was equal to that obtained by the combination of the resistant variety of Degra 1 with chemical insecticide. It is therefore, the variety of Degra 1 has a huge opportunity to be developed in leaf eating caterpillarsâ endemic soybean areas.

Soybean (Glycine max (L.) Merr.) is sensitive to salinity stress. The availability of soybean cultivar tolerant to salinity stress is the main key of succeeding of soybean cultural practice on saline affected land. Objective of the research was to evaluate the resistance of soybean germplasms to salinity stress. The research was conducted on saline affected soil in Lamongan District during the dry season (May-August) 2016. Nineteen soybean genotypes that were selected from previous salinity test in the green house were reevaluated in the field using a randomized block design with three replications. Wilis cultivar (sensitive to salinity) used as check. Variable observations consisted of soil properties before planting, number of plant grow at 13 and 41 days after sowing (DAS), plant height at 41, 56 and 71 DAS, chlorophyll content index at 27, 41 and 56 DAS, soil EC at 71 DAS, number of harvested plants, yield and yield components. The results showed that among 19 genotypes tested, only five genotypes that survived up to harvest with plant population 30-50% at high salinity level. Salinity reduced plant population more than 50%, and plant height only 50% from its normal height. Based on soil EC, plant population at harvest, and yield, genotype Karat 13, Grayak 3 and Grayak 5 were identified adaptive to high salinity level with soil EC 11,7-14,4 dS/m, while MLGG 0160 were identified adaptive to moderate salinity level with soil EC up to 9,1 dS/m.

The improvement of soil quality and agricultural increase using probiotic microbes have been proven in a variety of commodities including maize. The study was conducted to obtain the best formulation of microbial probiotic that is able to maintain seed quality and support the growth of hybrid maize (F1). The research was conducted at the Seed Science and Technology Laboratory, Bogor Agricultural University and continued in the experimental garden of Cikarawang, Kec. Dramaga, Kab. Bogor in March-December 2016. The two formulations of paste and liquid also six combinations of probiotic microbes were tested for viability and the seeds vigor using CRD two factor three replications. The experiment was continued by testing it effects toward plant growth with a split split plot design on three replications. The treatment factors were augmented with the use of NP fertilizer in 0%, 25%, 50%, 75% and 100% doses from the recommended doses. The six combinations of probiotic microbes used include: I1 (P24-AzL7), I2 (P24-AzL9), I3 (B28-AcCKB4), I4 (P24-AcCKB9), I5 (P24-AcCKB20), and I6 (P24-AcCKW5). The result shows that the paste formulation is more effective against the speed and synchronization of germination, while the liquid formulation is more effective against seed viability. The suitability of microbial probiotic formulation is influenced by microbial type and nutrient availability of plants. The formulations are not toxic for microbes and safe for seeds, so they are potentially further developed.
