Impact of Magnetic Water on Soil Fertility and Faba Bean Productivity under Reducing Phosphorus Fertilizer Rates in Salt aAffected Soils.

Faba bean (Vicia faba L.) maintain third place with respect to area and production among legume. Its unique ability to excel under all most all type of climatic conditions, it is one of the best performing crops under changing climate scenario. Its soil fertility augmenting potential and their performance was evaluated for two years with 73 accessions collected from Bihar. This study provides glimpses of scope and magnitude of soil fertility improving potential of faba bean (Vicia faba L.)

Faba bean production is a common practice in Lemu Bilbilo areas. However, faba bean productivity is affected and limited by poor soil fertility and lack of alternative technologies such as application of optimum phosphorus fertilizer for different faba bean varieties. In view of this, a field experiment was conducted on farmer’s field during the 2017 main cropping season at Lemu Bilbilo with the objectives to determine the response of faba bean varieties to different rates of P fertilizer and its influence on yield and yield components of faba bean varieties. The treatments include three faba bean varieties (Tumsa, Gebelcho and Dosha) and five phosphorus levels (0, 10, 20, 30 and 40 kg P ha-1) from Triple Super Phosphate. The experiment was laid out in a randomized complete blocked design with 3 x 5 factorial arrangements with three replications. Significantly (P<0 .05) higher plant height was recorded from Tumsa variety. Total productive tillers per plant, thousand seed weights, and harvest index and biomass yield of faba bean were significantly affected by main effect of varieties. Higher total productive tillers per plant (1.53) were obtained from application of 30 kg P ha-1. Higher plant height (153 cm), biomass yield (14158 kg ha-1) and grain yield (6323 kg ha-1) were obtained from application of 40 kg P ha-1. Application of 10, 20 and 30 kg P ha-1 gave marginal rate of return of 1404694 and 502% for faba bean production, which are well above the minimum acceptable rate of return. Therefore, application of 20 kg ha-1 of P with Tumsa, Gebelcho and Dosha faba bean varieties were proved to be productive and superior both in seed yield as well as economic advantage and recommended for faba bean production in Lemu Bilbilo area. Further study should be conducted in the future both over locations and years in order to give full recommendation for practical application.

ABSTRACT The usual application of high 4-14-8 NPK fertilizer rates in the potato planting furrows, independently of the soil fertility or nutritional cultivar requirements, has become a paradigm in Brazil. However, the 4-14-8 NPK formula does not always meet the crop needs, and can unbalance the availability of nutrients in the soil. The objective of this study was to evaluate the tuber yield and economic results of ‘Atlantic’ potato as affected by rates of 4-14-8 and 6-30-6 NPK formulas applied in the planting furrows. The rates of both NPK formulas were calculated to reach P2O5 rates of 210, 420, and 630 kg ha-1. At each P2O5 rate, the 6-30-6 formula resulted in less 30% N and 65% K2O in the planting furrow compared to 4-14-8 formula. A randomized complete block design in a factorial scheme (2×3)+1, including an unfertilized furrow control, with three replications was used. Only the use of 6-30-6 formula increased the total tuber yield of ‘Atlantic’ potato. The marketable tuber yield reached higher levels (29.8 t ha-1) with higher P2O5 rate (440 kg ha-1) using the 6-30-6 than 4-14-8 formula. The fertilizer rates and formulas NPK did not affect specific gravity of marketable tubers. Therefore, the use of a fertilizer more concentrated in P2O5 that favors smaller contributions of N and K (as the 6-30-6 formula studied in this work) provides lower costs, and greater operational efficiency and profits in relation to the 4-14-8 formula traditionally used for the potato crop.
