Effect On Yield

Effects of nitrogen, phosphorus and potassium fertilization were investigated on the change of nutrient content, vegetative and generative production of apricot, peach and sour cherry trees, as well as on frost hardiness in long term experiments. Nitrogen and phosphorus fertilization increased only the concentration of these elements in cherry leaves without effect on growth and yield. Consequent potassium effect was proved on these stone fruit species. Effect on yield appeared following the first higher crop load. Potassium supply has positive effect on frost hardiness of apricot and sour cherry flowers and peach flower buds. In peach, the lime content of soil decreased the yield but it could be compensated by potassium dressing to some extent. Favourable nutrient boundary values were determined for soil and foliage.

As part of the overall programme of research directed towards an understanding of fertilizer needs of crop plants in East Africa a study of the nutrition of maize in sand culture has been made.The purpose of the work was to study growth and yield in relation to changes in the proportion and concentration of the major nutrients, nitrogen, phosphorus and potassium, and if possible to relate the results to the field behaviour of the crop in fertilizer trials conducted by another section of this organization. Simultaneously studies of the uptake of nitrogen and phosphorus were also undertaken. These latter are discussed in the second paper of this series.This first paper deals only with growth, yield and nutrient content in relation to the nitrogen phosphorus balance, though the methods now to be described were common to all experiments.

An experiment was conducted in field condition to study the effect of nitrogen-phosphorus fertilization on growth, yield and nutrient content of cabbage. The experiment was laid out in randomize block design with three replications. The yield and yield components were maximized by N3P2 fertilizer treatment. Nutrient content of cabbage varied with fertilizer treatment. The maximum amount of reducing sugar, ascorbic acid, phosphorus were found at the highest rate of N - P fertilization whereas accumulation of titrable acidity, iron, calcium were maximum at the rate of N2P2 treatment. However pH, ash content were more or less same throughout the experiment. Bangladesh J. Sci. Ind. Res. 41(1-2), 41-46, 2006

The objective was to evaluate the effect of different doses of nitrogen and phosphorus on growth and development of Hemerocallis fulva variety Flore Full, herbaceous perennial widely used in landscaping. The experimental design was randomized blocks with 25 treatments, arranged in a factorial 5 x 5 (0; 75; 150; 225 and 300 kg ha-1 N and 0, 100, 200, 300 and 400 kg ha-1 P), with 4 replicates. The phosphorus fertilization was carried out 15 days after planting (DAP) and nitrogen was applied in coverage divided in three equal applications at 15, 120 and 240 DAP. There were evaluated the plant height, number of tillers per plant, soil coverage area, the fresh mass of plant, root system and shoot; and the dry mass of plant, root system and aerial part, and calculated the ratio of root dry mass and plant dry mass. It was also obtained the nutrient content of the leaf tissue and root system. The highest tillering was gained with the use of 150 kg ha-1 N combined with 400 kg ha-1 of P. Intermediate doses of N (75-170 kg ha-1 of N) showed higher production of plant fresh and dry mass and root dry mass. Doses of N and P influenced the N and P content in plant tissues of roots and leaves of Hemerocallis. Plants fertilized with 300 kg ha-1 of N and 273 kg ha -1 of P lead to the highest levels of N in the leaves and doses of 80 kg ha-1 of N and 68 kg ha-1 P, the highest content of P in the leaves of H. fulva. Already, in the roots, the highest N content was obtained with application of 300 kg ha-1 N in the presence of P and doses of 225 kg N ha-1 combined with 300 ha-1 P provided the highest P content in the roots.

Binucleate Rhizoctonia (BNR) fungi are essential for the germination of vanilla seeds. Chemical control of the soil-borne pathogen might adversely affect BNR. The purpose of this study is to determine the effect of Nicotiana tabacum extract biopesticides and Fusarium oxysporum f.sp. vanillae (Fusarium) on vanilla plant nutrient content induced by BNR. Materials and Methods. The research design was completely randomized design with two factors and three replications. The first factor was biopesticide (dosage of 0, 10, 20, and 30 ml/seedling), and the second factor was the application of Fusarium. Results. The increase in the nitrogen, phosphorus, and potassium content of vanilla was affected by biopesticides and Fusarium inoculation. Fusarium inoculation has no significant effect on nitrogen and phosphorus levels but significantly affects potassium levels. The biopesticide dosage is significant for nitrogen, phosphorus, and potassium. The interaction of biopesticides with Fusarium inoculation did not significantly affect the parameters of nitrogen and phosphorus content, but significantly affected potassium content. Conclusion. The application of biopesticides and Fusarium inoculation after induction of BNR can increase nitrogen, phosphorus, and potassium content of vanilla plants.

Afield experiment on French bean was conducted in Old Brahmaputra Floodplain Soil of Jamalpur and Grey Terrace Soil of Joydebpur during 2005-2006 to find out the optimum rates of N and P for yield maximization. Four levels of nitrogen (0, 100, 150 and 200 kg ha-1) and 3 levels of phosphorus (0, 40 and 60 kg ha-1) were used in the experiment. Potassium (K) 80 kg, sulphur (S) 10 kg and 5 t cowdung ha-1 were applied as a basal dose. The experiment was laid out in a randomized complete block design with 12 treatments replicated 4 times. Nitrogen and phosphorus alone significantly influenced the pod yield of French bean. Among the N levels, the highest pod yield (13.33 t ha-1 at Jamalpur and 14.68 t ha-1 at Joydebpur) were obtained with 150 kg N ha-1. Among the P levels, the highest pod yield (12.35 t ha-1 at Jamalpur and 13.69 t ha-1 at Joydebpur) were obtained with 60 kg P ha-1. Interaction effect was not significant. However, highest pod yield (13.60 t ha-1 at Jamalpur and 15.05 t h-1 at Joydebpur) was obtained from 150 kg N plus 60 kg P ha-1. Economic analysis showed that 150 kg N plus 40 kg P ha-1 gave the highest gross margin of Tk. 1,66,684/ha.

The present field experiment was conducted at Agricultural Research Farm of RBS College, Bichpuri Agra, during Rabi season of 2018-19. The soil of the experimental site is Gangetic alluvial. The experimental was laid out in RBD factorial having 3 main treatment (N level) and 4 sub treatments (P2O5 level) with 3 replications. All growth and yield attributing character increase with application of N @ 120 Kg-1 and P2O5 @ 60 kg-1. All the yield components i.e., number of siliquae plant-1, length of siliqua and number of seeds siliqua-1 improved with the increase in the level of nitrogen. Higher value of harvest index was associated with the application of 60 kg P2O5 ha-1. Seed yield increased appreciably with every additional increase in the level of nitrogen. Respectively 26.85 and 40.05 per cent higher seed yield ha-1 was obtained with the application of 80 and 120 kg ha-1 nitrogen as compared to 40 kg ha-1 .

A field study was conducted at Agronomy Research Farm of Punjab Agricultural University during kharif 2013 to evaluate the effect of organicand inorganic sources of nitrogen on maize. Experiment was laid out in split plot design with four replications comprising three farmyardmanure levels (0, 15 and 20 t/ha) in main-plots and five nitrogen levels 0, 75, 100, 125 and 150% of recommended dose (125 kg/ha) throughinorganic fertilizer in sub-plots. Plant growth and yield characters and nutrient content as well as uptake were recorded. Number of leaves, leafarea index, chlorophyll content and leaf nitrogen content at periodic intervals increased significantly with the application of farmyard manureand nitrogen. Increase in nutrient uptake viz., nitrogen, phosphorus and potassium uptake along with micronutrient uptake by grain was alsoobserved with incremental farmyard manure and nitrogen levels. Growth variables were correlated positively with each other and with grainyield. A fairly negative correlation was observed between micronutrient content and growth and yield variables.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11849 Int J Appl Sci Biotechnol, Vol. 3(1): 31-37
