Salt solubility is the abiotic pressure which has the most effect on the loss of plant quantity and quality. Salinity not only makes plants stressful but also presents severe constraints on crop production so an attempt to understand plant adaptation mechanisms is important for expanding agricultural production on saline soils. This study aimed to obtain a mechanism for the adaptation of hybrid and composites maize to NaCl stress through anion and cation absorption patterns. The experiments were carried out at the LLDikti Region X Laboratory from May to August 2016. The experiments were arranged in a factorial complete randomized design with three replications. The first factor was corn varieties, namely: hybrid corn (Pioneer 22 and Bisi 12), and composite corn (Bisma and Sukmaraga). The second factor was level of NaCl, namely: 0.0 mg kg-1 NaCl pH 5.0, and 4,000 mg kg-1 NaCl pH 5.0. Measurement of anions and cations using Spectroquant Thermoreator TR Nova 420. The adaptability of hybrid maize and composites to NaCl stress occurred through the mechanism of anion absorption and cation metabolism. The difference in the percentage of NO3-, NO2-, PO4-, NH4+, and K+ levels between hybrid maize varieties and composites showed a difference in the adaptation ability of maize varieties to salinity stress.

“…The results of research on several tolerant plant varieties such as corn, soybeans, wheat, ground cover legumes and rice showed the ability of plant roots to continue to grow and develop well even in nutrient-choked conditions [6,9]. Adaptability of plants to stress, can also occur through the metabolism of nitrate (NO 3 -), ammonium (NH 4 + ), nitrite (N0 2 -), phenolic acid as indicated by differences in levels of NO 3 -, NH 4 + and N0 2 between sensitive and tolerant species [13] The main difference from the adaptation mechanism is in the area where the binding occurs, whether in the simplas or apoplas. Both of these mechanisms can occur simultaneously, although in different degrees according to the type of plant and its ability to adapt [31,32].…”

Increased production, many face increasingly complex challenges. The problem, which is not less important is the limited rice varieties tolerant to iron stress. The aim of the study was to obtain growth and distribution patterns of Fe2+ ions in several hybrid rice varieties. Experiment in Koto Baru, Sitiung I, Dharmasraya Regency, West Sumatra. The experiment used a completely randomized design, with five replications. The single factor is rice varieties, namely: Mekongga, Inpari 24, Inpari 27 and Inpari 28. The paddy fields used contain 104.69 mg kg-1 Fe2+, these concentrations greatly affect growth which causes poisoning. The production of milled dry grain in all varieties remained high even though it was iron-strapped, because the number of productive tillers formed in the SBSU system was more than 21 stems per clump, with production of grain weight > 5.4 Mg ha-1. The pattern of iron distribution occurs through absorption and translocation in the vegetative and generative phases to roots, stems, leaves, grain, and rice. The difference in iron levels in each part shows the ability of each variety to adapt. To obtain rice grains rich in iron and able to grow and produce well in iron-clamped conditions, it is recommended that aquaculture using the SBSU system with Inpari 27 varieties be able to produce iron content in rice grains of more than 27 mg kg-1 with production of grain weight 6.83 Mg ha-1.

A field experiment was carried out to study rice growth under salinity stress in permanently flooded, intermittent, and saturated soil conditions. The experiment was conducted at field station of Faculty of Agriculture, Universitas Gadjah Mada located in Bantengan village, Banguntapan, Bantul, DIY, from August to November 2015. The treatments were arranged in a split-plot randomized complete block design, consisting of three irrigation methods as the main plot and two levels of salinity as the subplot, thereby resulting in six treatment combinations with three replications within each combination treatment. The three irrigation methods were permanent irrigation (flooded soil), intermittent irrigation (wet/dry soil), and irrigation above field capacity (saturated soil). The two levels of salinity were fresh water as control treatment (EC  0.3 dS.m-1) and saline water (EC  5 dS.m-1). The results of the experiment showed that there was no significant interaction effect of irrigation method and salinity on all observed rice growth variables. Salt stress negatively affected the rice growth, including plant height, plant dry weight, leaf area, and leaf area ratio (LAR). Irrigation method significantly affected plant dry weight and number of tillers at 3 and 9 weeks after planting. Permanent irrigation resulted in the highest plant growth compared to intermittent irrigation and above field capacity condition.
