In this research, effect of tillage and planting methods (planting on permanent raised beds, no-till, and conventional tillage) on soil properties such as bulk density, moisture content, and organic carbon and water consumption, water productivity, and crop yield was evaluated in the form of randomized complete blocks experimental design with three treatments and six replicates in corn-wheat rotation. Results showed that the raised bed planting had the maximum forage corn (95.33 ton/ha) and wheat yield (7.01 ton/ha) and no-till had the minimum silage corn (87.06 ton/ha) and wheat yield (5.23 ton/ha) which had no significant difference with the conventional tillage. Forage corn consumed the maximum water (9531 m3/ha) in the conventional tillage and the minimum water (8155 m3/ha) in no-till; while, there was no significant difference between treatments from the water productivity point of view. Wheat consumed the maximum water (7177 m3/ha) in raised bed planting, but there was no significant difference between treatments from the stand point of water productivity. Results also showed that conservation tillage methods increased soil moisture content in forage corn planting (around 11%), but had no significant effect on the soil moisture content in wheat planting.

In this research, effects of water sprayed over the upper layer of the mowed and rowed alfalfa (before baling) on quantitative and qualitative losses of alfalfa during baling process were evaluated. The study was conducted in the form of split plot experiment with 12 treatments and three replications from 2020 to 2022. Main plots were the amount of water sprayed on the alfalfa with four levels of water (0, 250, 350, and 450 liters per hectare). Subplots were the time interval between spraying water on alfalfa and baling operation (0, 30, and 60 minutes after spraying water). Alfalfa losses at the baler pickup and compression chamber, during transportation, and total losses were measured. Alfalfa dry matter, crude protein, fat, organic matter, ash, acid detergent fiber, neutral detergent fiber was measured, and amount of aflatoxin were also detected after six months of storage. Results showed that spraying 450 L water per hectare decreased alfalfa losses at baler pickup and compression chamber, transportation, and total losses by 20.4, 34.3, 4.7, and 21.1% respectively, compared to the control treatment. Time interval between spraying water on alfalfa and baling time had no significant effect on alfalfa losses during baling operation and transportation. Results also indicated that spraying water on alfalfa before baling operation had no significant negative effects on alfalfa quality after six months storing and did not reduce alfalfa quality during storing time.
