Mathematical Modeling for the Influence of Nitrogen Fertilization Level on Vegetative Growth and Yield Attributes of Broccoli

The field experiment was carried out during rabi season of 2018-2019 at Research farm, Raja Balwant Singh College, Bichpuri Agra,(U.P) to study the effect of different concentrations of zinc and boron as foliar spray on the vegetative growth and yield of cauliflower (Brassica oleracea var.bortrytis). Nine treatments with three replications were evaluated in randomized block design. The results revealed that the maximum plant height (44.90 cm), diameter of stem (1.68cm), length (38.90 cm) and width (24.55 cm) of longest leaf were recorded with the foliar spray of 0.50% Zn + 0.2% boron solution .The maximum values of spread of plant along the row(53.51cm)and across the row (55.25 cm) and fully opened leaves per plant (12.94) were recorded with the foliar spray of 0.25% Zn +0.2% boron solution. The yield of cauliflower curd was recorded maximum (343.46 q ha-1) with foliar application of Zn (0.50%) + boron (0.2%). The increase in yield with this treatment was 23.9 % higher than obtained with control (277.13 q ha-1).The lower values of growth and yield attributes were recorded under control .In general combined application of zinc and boron was found significantly superior over their alone application

Abstract: The objective of this work was to evaluate the effect of nitrogen fertilization on the mineral composition of leaves, initial growth, and yield of peach (Prunus persica) tree advanced selections grown at a high-planting density. The experiment was carried out between 2012 and 2015 in a randomized complete block design, with a combination of advanced selections of the 'Cascata 1513' and 'Cascata 1067' peach trees and of N fertilization doses (0, 30, 60, and 120 kg ha-1 N). Green weight after pruning, diameter, and increase of trunk diameter, canopy volume, plant height, branch length, number of buds per centimeter of shoot, chlorophyll index, leaf area, rust incidence, average production, number of fruit, and mass of fruit were evaluated. Genotype affects the vegetative growth and productive performance of peach trees. The application of N to dense peach orchards promotes a greater vegetative growth of the plants and increases the content of the nutrient in leaves. The initial production is affected by N fertilization. The recommendation of N fertilization made to date is insufficient for peach trees at high-density management systems of production.

The vegetative growth, yield attributes and yield of garlic depends on timely planting, planting system and high yielding cultivar. The purpose of this experiment was to investigate the effects of planting time, planting system with variety on the growth and yield of garlic germplasm. Two experiments were performed during the study, and the experiments were laid out in Randomized Complete Block Design (RCBD). Four planting time (such as 26 October, 9 November, 20 November and 10 December), two factors for planting system (such as zero tillage and dry land) and four varieties (such as BAU garlic-1, BAU garlic-2, BAU garlic-3 and G-51) were considered during the experiments. The results revealed that the planting time had significant influence on growth parameters, yield attributes and yield of garlic. The highest values of growth parameters as well as bulb yield (10.33 t/ha) were obtained at 26 October whereas the lowest values were recorded at 10 December resulting bulb yield (8.47 t/ha). On the other hand, the planting system had also significant influence on the vegetative growth and yield of garlic. The highest values of growth characters, yield attributes and yield of garlic was found in zero tillage compared to dry land. BAU Garlic-3 was provided the highest growth as well as bulb yield among other three varieties. It was also noticed that, the combined treatment of zero tillage and variety of BAU Garlic-3 gave the highest values of growth and yield attributes as well as bulb yield (8.80 t/ha) parallel with other combined effects. Results expressed that the early planting and the combination of zero tillage and BAU Garlic-3 variety has given the profound effects on the growth parameters as bulb yield of garlic.

Synthetic Fertilizers

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.
