Result Analysis

The productivity of onion crop is poor due to inappropriate management and agronomic practices in Bangladesh. To figure out the effect of NPK fertilizer rate and spacing on growth parameters of onion a field experiment was conducted. The treatments were consisting of N fertilizer (0, 80,120 and 160 kg/ha), P fertilizer (0, 30, 50 and 70 kg/ha), k fertilizer (0, 50, 75 and 100 kg/ha) and three plant spacing viz., 10 cm × 10 cm, 15 cm × 10 cm and 20 cm × 10 cm. The experiment was designed in RCBD with three replications. Analysis of results indicates that the interaction effect of NPK rate and spacing shows significant (P<0.05) effect on plant height. Highest plant height was obtained in 20 cm × 10 cm spacing and application of 160 kg N/ha, 70 kg P/ha and 100 kg K/ha respectively. Moreover, maximum number of leaves was also found by plants spaced at 10cm and application of highest dose of fertilizers. Lowest plant height and number of leaves was attained in 10 cm × 10 cm spacing and without NPK fertilizer application. The total result analysis reveals that best growth performance of onion was found from 20 cm × 10 cm spacing combined with 160 kg N/ha, 70 kg P/ha and 100 kg K/ha fertilizer amendment. Res.

This study was aimed at assessing the growth and production of celery plants grown with various compositions of N,P and K fertilizer and compost. The study was done at the Trial Farm of Faculty of Agriculture, Djuanda University, Bogor fiom September to November 2015. A completely randomized design with two factors was used. The factors consisted of compost rate and N,P and K fertilizer rate. Compost was given in four levels, namely no compost (0% R), 26.3% gcompost/plant (50% R), 52.5 g compost/plant (100% R), and 78.7 g compost/plant (150% R). N, P and K fertilizer was given in five levels, namely no fertilizer (0% R), 4 g Urea, 0.3 g SP-36, 0.2 g KCl (25% R), 0.9 g Urea, 0.6 g SP-36, 0.4 g KCI (50% R), 1.3 g Urea, 0.8 g SP-36, 0.6 g KCl (75% R), and 1.7 g Urea, 1.1 g SP-36, 0.8 g KCl (100% R). All fertilizers were administered gradually at the time of planting and 2 weeks after planting. Three replicates were allocated into each treatment making up 60 experimental units. Results showed that celery plants given synthetic fertilizer at 100% R had higher plant height, number of leaves, number of seedlings, harvest fresh weight (g), saleable fresh weight (g), root biomass (g), and root dry weight (g) than those treated with no fertilizer (0% R). Plants treated with 150% compost had higher plant height, number of leaves, harvest fresh weight (g), saleable fresh weight (g), root length (cm), and root dry weight (g) than those treated with no fertilizer (0% R). Thus the best celery growth and production in this study was obtained on plant 150% R compost   and 100% R synthetic fertilizer nourished.Key words: celery, compost, N, P, K fertilizer, harvest flesh weight

Preplant irrigation can impact fertilizer management in winter wheat. The objective of this study was to evaluate the main and interactive effects of preplant irrigation, N fertilizer application timing, and different N, P, and K fertilizer treatments on grain yield and WUE. Several significant two-way interactions and main effects of all three factors evaluated were observed over four growing seasons for grain yield and WUE. These effects could be described by differences in rainfall and soil moisture content among years. Overall, grain yield and WUE were optimized, if irrigation or adequate soil moisture were available prior to planting. For rain-fed treatments, the timing of N fertilizer application was not as important and could be applied before planting or topdressed without much difference in yield. The application of P fertilizer proved to be beneficial on average years but was not needed in years where above average soil moisture was present. There was no added benefit to applying K fertilizer. In conclusion, N and P fertilizer management practices may need to be altered yearly based on changes in soil moisture from irrigation and/or rainfall.

The Difference

SUMMARYSixty-one experiments with 15 levels of K fertilizer in the presence of excess N and P fertilizer were carried out on adjacent sites of the same field. Yield was always related to level of K fertilizer by a ‘diminishing returns’ type curve, and a derived equation, which defined relative responsiveness in terms of a single parameter, fitted the data for each crop very satisfactorily. Although the responsiveness of many of the crops was similar there were marked differences and the optimum levels of K (defined as the level at which a further 10 kg/ha increased yield by 1%) varied from 0 to 360 kg/ha, depending on the crop. Responsiveness was largely independent of the plant family to which the crop belonged, but was related to the mean plant weight atharvest; the larger the weight the less reponsive the crop. No general relation existed between responsiveness and duration of growth.The % K in the dry matter of leaves (including stems) at harvest of crops receiving the optimum levels of K fertilizer was mainly determined by the family. It was generally between 0·9 and 1·1 for the Amaryllidaceae, between 1·1 and 1·2 for the Leguminosae and between 1·9 and 2·5% for the Cruciferae. The difference between the % K in the dry matter with the optimum level of K fertilizer and that with no fertilizer was proportional to responsiveness. Percentage K at harvest was a good indicator of the extent to which crop growth was restricted by lack of potassium.At harvest crops receiving the optimum levels of K fertilizer contained between 29 and 220 kg/ha of K, but uptake increased asymptotically to a maximum as K applications were raised to higher levels. Maximum uptake for nearly all crops was almost double the uptake with the optimum fertilizer application.Percentage recovery of 100 kg/ha of added K fertilizer varied between 8 and 70%, roughly in proportion to the total crop dry weight, which varied between 1 and 15 t/ha.Effects of level of K fertilizer on crop quality were also measured and over the practical range of applications the effects were generally small.The differences between the K requirements of crops are discussed and it is argued that the responsiveness of one crop relative to that of another would be expected to be similar on a range of soils.
