The purpose of this research was to assess the crop rotation affects on agronomic traits of soybean in optimal (OCS) and dry cropping seasons (DCS). This research was carried out in 2010/2011 (OCS) and 2011/2012 (DCS) in a Rhodic Hapludox soil. The experimental design was set up in a randomized complete block and the treatments were arranged in a factorial 9 x 2, consisting of 9 crop rotations systems and two cropping seasons, with four replications. The soybean (Glycine max cv. BMX-Potência RR) was sowed on October 20 th 2010 and October 10 th 2011 (spring-summer season) 20 days after the fall-winter cover crops desiccation. It was assessed in the R8 reproductive stage (Full maturation) the plant height, the height of the first pod insertion, number of pod per plants, number of branches per plant, number of seed per pod, 1000-grain weight and grain yield. It was observed that in drought stress (DCS), the number of branches decreased, this reduction was 36% in relation to OCS. For the traits as plant height, first pod height, 1000-grain weight and yield, it was showed small values in DCS in contrast to OCS. It is feasible to introduce these cover crops in fall-winter season to make part of a crop rotation system. The number of pod per plant showed higher values under the crop rotation of corn/rapeseed/soybean, which showed highly associated with the soybean grain yield. This research brought options for cover crops system to be viable in no-till system with soybean in spring-summer season.

“…Mirakhori et al [16] studied drought stress and methanol on yield and yield components of soybean in field experiments with factorial experiment in the form of a randomized complete block design with three replication in field. First factor were sprayed aqueous solutions 0 (control), 7, 14,21, 28 and 35% (v/v) methanol by 3 times during growth season of soybean with 12 days intervals on shoot of soybean.…”

To study "the effect of drought stress on Tomato (Lycopersicon esculentum) Cv. Bombino" an experiment was conducted at Institute of Biotechnology and Genetic Engineering, Agricultural University Peshawar. Tomato plants were grown in green house under two different conditions of water availability i.e.-controlled and drought. The parameters studied were relative water content (%), proline content (µmoles) and relative growth rate (weekˉ1). Drought stress has significant effect on all parameters studied. The relative water content of plant body decline during drought due to less water availability. In controlled environment, the mean value of relative water content was 89.28 while that observed in drought condition was 87.73. Proline was observed on rise due to continuous decrease in water quantity in cell sap. The value of proline content is 4.4 µmoles gˉ1 fresh weight in controlled condition whereas that the plants in drought condition had 5.8 µmoles gˉ1 fresh weight. Due to less water, photosynthesis was negatively affected which resulted in less energy production and finally low growth. In controlled condition the relative growth rate weekˉ1 on fresh weight was 1.37 gm whereas that of plant in drought condition was 0.57 gm.

“…Water also have been a limited resource in agriculture and its must be use efficiently. Water also one of the most important limiting factors in plant growth other than Nitrogen (Sajedi et al, 2009;Mirakhori et al, 2009;Schindler et al, 2007;Xu and Yu, 2006;Fan and Zhang, 2000). In plant relations, determination of the water requirement of plant is important for agriculture in dry regions (Gholizadeh et al, 2010;Fuller and Harhay, 2010).…”

Problem statement: Rubber has been grown more than a century in South East Asia, who has been the largest producer of natural rubber. Demand of natural rubber increases steadily due to increasing demand particularly from developing countries. Water has been a limited and invaluable resource especially in agriculture. This resource has to be used wisely and there is a need for a detailed study pertaining to water requirement of rubber plants. This study provides details about rubber plants growth in relation to water stress. Approach: Two new latex timber clones from Malaysia Rubber Board (MRB), RRIM 2005 and RRIM 3001 were used in this study with soil from Haplic Ferralsol used as planting media. Five levels of treatment were used; plants irrigated for every 2, 5, 10 and 15days and everyday which acted as control. The experimental design used was a Completely Randomized Block Design (RCBD) with four replications. Results: Results showed treatment well watered for clone RRIM 2025 (T6) had most the turgidity with high mean value in stomata conductance and chlorophyll content. RRIM 2025 also more resist to water stress compared to RRIM 3001. All plants in treatments with extreme different in water regimes cannot survive and dead due to severe stress. Conclusion: This study found rubber clones RRIM 2025 and RRIM 3001 cannot survive with acute deficiency of water. Rubber cannot be planted in dry areas with low water regimes which will retard the plant growth and plant will die under severe water stress
