This research aimed to determine site specific NPK fertilizer rates combined with rice straw compost application for rice grown on the tidal lowland. This research was conducted in a greenhouse in Indralaya, Ogan Ilir, South Sumatera in February  until September 2017 using a factorial completely randomized design with two factors and three replications. The first factor was NPK fertilizer rate calculated based on the results of soil chemical analysis, consisting of five levels, namely 50% (D1), 75% (D2), 100% (D3), 125% (D4) and 150% (D5) of the site-specific fertilizer rate. The second factor was rice straw compost rate consisting of two levels, namely 5 Mg ha-1 (J1) and 10 Mg ha-1 (J2). The results showed that the application of 150% NPK rate and 10 Mg ha-1 rice straw compost resulted in the best effects on the rice growth grown on the tidal lowland. The application of those fertilizer doses produced the highest maximum number of tillers and productive tillers. In this regard the doses of NPK fertilizers that should be applied are 315 kg urea ha-1, 135 kg SP-36 ha-1 and 90 kg KCl ha-1.

Tidal acid land is a potential land for cassava development. However, the development of cassava in tidal land faces many obstacles, one of which is the low availability of nutrients. This study aimed to determine the effect of NPK fertilizer in increasing the growth and yield of cassava in tidal land. The experiment consisted of two factors, the first factor was two varieties of cassava and the second factor was four levels of NPK fertilizer doses. The experiment was applied in a strip plot design with variety as the horizontal factor and the level of NPK fertilizer as the vertical factor and repeated three times. The growth parameters observed consisted of plant height, stem diameter, plant biomass weight, number of large tubers, number of small tubers, large tuber length, length of small tuber, the diameter of large tuber, the diameter of small tuber, the total number of tubers, the weight of large tuber, the weight of tuber small, and total tuber weight. The results showed that fertilizer application was effective in increasing vegetative growth and yield of cassava but increasing the dose of fertilizer was not effective in increasing the growth and yield of cassava. Differences in varieties generally did not show differences in vegetative growth and some yield components but still showed different results in the components of tuber length and total tuber weight.

Two experiments were carried out during the summer season, 2016, in the green house / Department of Biology/Collage of Education, Samarra University, to evaluate the activity of three aqueous extract of leaves of Nerium (Nerium oleander L.),olives (Olea europaea .L) and castor (Ricinus communis.L), on control of tuber germination and growth of seedling of Cyperus rotundus L as an alternative for chemical pesticides. Experiments applied according to the complete randomized design (CRD) with four replicates. The experiments included two factors: the first factor plant species (three plant species),and the second factor concentration of plant extracts (2.5%, 5% and 10%) and their impact on germination rate and inhibition of seedling growth. The results of the first experiment recorded inhibition percentage reached (90%) at 5% and 10% from Nerium extracts compared with the same concentrations from Olive and Castor which, recorded inhibitory rate reached (30-40%) respectively. While the concentration of 2.5% was the lowest inhibition rates for germination ratio of all plant extracts under study. The second experiment showed effect of the Nerium extract at a concentration (10%) by recording completely inhibition ratio (100%), compared with the same concentrations of Castor and Olive extracts, which recorded the lowest mean growth inhibitory for all extracts. The results of the current study indicate the possibility of using natural products of plant origin as alternatives to chemical pesticides as one of the means of biological control in the management program agricultural sector with further studies of the future.

Cyperus rotundus L. and Ageratum conyzoides L. are commonly found in tomato field as weeds species. Weed compete with the crop for nutrient, water and light. In addition, weed released allelopathy that inhibited the growth of crop. The aim of this study was to compare the ability of allelopathy from C. rotundus L. and Ageratum conyzoides L. root extract to inhibit tomato plant growth. The study was conducted in Completey Randomized Design with two factors. The first factor was root extract from either C. rotundus L. and A. conyzoides L. as allelopathy. The second factor was concentration of root extract from both weeds (100, 300 and 500 g/ml). Each treatment combination was repeated four times. The results showed that A. conyzoides L. root extract had higher inhibition to growth of tomato plant than C. rotundus L. root extract. Increasing root extract concentration from both weeds increased inhibition of tomato plant growth.
