dc.descriptionIn the present investigation entitled "Effect of different levels of nitrogen and phosphorus on growth, yield and quality of sweet corn (Zea mays (L).var. Saccharata)”was studied. Recently the demand of sweet corn is increasing every year by consumer particularly in urban area because of its sweet taste and high nutritional value as well as demand for processing and by hotels. Compared to the global growth in the production and consumption of corn, the production of corn is not registering adequate growth in India (Venkatraman 2007). Further, the yield per hectare of corn cultivation in India remains much lower than the levels in USA and China. So the price of corn in India is also now steadily going up. Rapid increase of corn production is of vital importance to India. In recent year sweet corn gaining the popularity among growers. However the location specific technologies for sweet corn are not available. Application of fertilizers viz. nitrogen and phosphorus levels has greater influence on growth, yield and quality of sweet corn. Therefore there is urgent need to find out proper application of nitrogen levels with phosphorus levels for sweet corn.en_US
dc.description.abstractAn experiment entitled “Effect of different levels of nitrogen and phosphorus on growth, yield and quality of sweet corn (Zea mays (L).var.Saccharata)” was carried out in summer season of 2017 at the Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). The experiment was laid out in Factorial Randomized Block Design (FRBD) with three replications and fifteen treatment combinations with factor A. nitrogen levels viz. N¬1 -100 kg ha-1, N2-125 kg ha-1, N¬3 -150 kg ha-1, N4 -175 kg ha-1 and N5 - 200 kg ha-1.and factor B phosphorus levels viz. P1 - 40 kg ha-1, P2 - 60 kg ha-1 and P3 - 80 kg ha-1. Growth and yield parameters were significantly influenced by nitrogen levels, treatment with application of nitrogen N5 (200 kg ha-1) recorded significantly higher plant height, number of leaves, stem diameter, leaf area, plant height, total chlorophyll content, minimum days to 50 percent tasseling, 50 percent silking and cob harvest. It also recorded significantly higher cob weight, cob weight plot-1, cob length, cob girth, number of cob plant-1, number of grains cob-1, grains weight cob-1, fodder weight plot-1. Quality parameters like reducing sugar, non reducing sugar, protein content, TSS influenced by different levels of nitrogen was found non significant effect on the basis of one year data. The soil and plant nutrient status was also found to be improved with the application of nitrogen N5 - 200 kg ha-1. Application of phosphorus P3 - 80 kg ha-1 recorded significantly higher growth parameter, yield parameter, soil and plant NPK .but found non significant in quality parameter on the basis of one year data. Among all the treatment combination N5P3 (200 kg + 80 kg N:P2O5 ha -1) was found superior for growth parameters (plant height, number of leaves, leaf chlorophyll content, leaf area, stem diameter, days to 50 percent tasseling , 50 percent silking and cob harvest). It was also found superior for yield parameter (cob weight, cob weight plot-1, cob length, cob girth, number of cob plant-1, number of grains cob-1, grains weight cob-1 and fodder weight plot-1). Quality parameters like reducing sugar, non reducing sugar, protein content, TSS content influenced by different levels of nitrogen, phosphorus was found non significant effect on the basis of one year data. Therefore, nitrogen level 200 kg ha-1 along with phosphorus level 80 kg ha-1 is best suited for obtaining higher yield of good and quality sweet corn. The soil and plant nutrient status was also found to be improved with the application of nitrogen and phosphorus combination N5P3 (200 kg+80 kg N: P2O5 ha-1).The benefit: cost ratio was also observed maximum i.e. 1: 3.68 for treatment combination N5P3 (200 kg 1 + 80 kg N: P2O5 ha-1).en_US
