Stimulation Growth and Yield of Potato by Buttonwood Prunning Residues and Spraying Several Micronutrients

Abstract

This study was aimed to estimate the influence of Conocarpus erectus L. residues, and some micronutrients on growth and production of potato. This research was conducted at one of the fields of the College of Agricultural Engineering Sciences - University of Baghdad. The experiment was implemented using factorial arrangement (4X3X3) within randomized complete block design with three replicates. Conocarpus fertilizer was represented the first factor with three levels (7.5, 15, 30 ton.ha-1), which symbolized (C2, C3, C4). Mineral fertilizer as recommended dose as a control, which symbolized (C1). The second factor was foliar spraying with three levels of iron (0, 100, 200 mg.L-1), which symbolized (F0, F1, F2). The third factor is foliar spraying with three levels of boron (0, 50, 100 mg.L-1), which symbolized (B0, B1, B2). Results revealed that the treatments C1 and C3 produced significant results in most of studied traits such as, Leaves number (71.74, 82.26 leaves plant-1), leaves chlorophyll content (223.30, 174.11 mg 100g wet weight) and total yield (84.24, 51.98 ton h-1) for both seasons respectively, while C1 and C4 produced the most significant protein percent reached (7.53, 7.71%) respectively. The foliar application of Fe at F2 produced the highest results in leaves number (70.47, 80.18 leaves plant-1), protein percent (7.40, 7.55%) for both seasons respectively, Also the foliar application of Boron at B1 and B2 produced a significant results in leaves number (68.58, 78.71 leaves plant-1), total yield (48.47, 76.00 ton h-1), and protein percent (7.43, 7.49%) for both seasons respectively. Furthermore, the third order interaction at the treatment C3F2B2 produced the highest protein percent (7.78%) in spring season only.

Role of Organic Fertilizer and Boron Foliar Application on Growth and Productivity of Potato for Processing

“…While the level of organic fertilization O 36 recorded the highest leaves content of boron for the fall season and at the level of O 24 for the spring season reached 56.65 and 51.60 mg. kg -1 , respectively, compared to control treatment (O 0½ ), which recorded the lowest values for all parameters which were the leaves content of Chlorophyll (202.23 and 165.98 mg.100g wet weight -1 ), N (3.813 and 2.102 %), P (0.404 and 0.219%), K (2.234 and 2.498 %), B (47.30 and 36.15 mg.kg -1 ) for both seasons, respectively. These results could be attributed to the role of organic fertilizers, as the percent of nutrients in the soil increased by the decomposition of organic matter, which increases the nutrients availability for absorption, and reflected on their concentrations in the plant (4,5,9,13). The increase in leaves content of chlorophyll is due to the increase in nitrogen released in the soil as a result of the application of organic fertilizers, which increased the accumulated nitrogen in the plant.…”

Effects of Mineral Fertilization and Spraying With Salicylic Acid and Amino Acids on the Growth and Productivity of Industrial Potatoes

“…It is used for domestic consumption, while the other part goes to the manufacturing process (17). In the last century, several methods were taken to improve the growth of the potato plant and increase its productivity per area unit (5,6,14) ;especially potato for processing issues (11,12,28). Including increasing the quantities of mineral fertilizers used (29), as they are an important source to secure the crop's need for nutrients (33), so it is necessary to reconsider the applied aspects of current agricultural operations and use methods that improve efficiency of nutrient use (34).…”

Spraying Nano Chitosan Loaded With Npk, Nettel and Green Tea Extracts as a Tool for Improvement Potato Productivity

“…Potato (Solanum tuberosum L.) is the most important crop in agricultural production that mainly contributes to the economic profitability and food security of Iraq. Consequently, our local society has a great need to increase its production capacity (6,7,23) in particular; potato varieties for processing (20,21,41,42). The addition of Nano fertilizers is an efficient way was applied to several crops and improved their growth and productivity as in tomato (43), broccoli (37), date palm (31) and bread wheat (2,25).…”
