Description |
A field experiment in factorial RBD was conducted during Rabi, 1988 on sandy loam soil (pH 7.8, available N 150.0 kg/ha available P 22 kg/ha and available K 174 kg/ha) at Botanical cum Horticultural garden, College of Agriculture, Rajendranagar, Hyderaba~ to evaluate the effect of graded levels of N and P application each at 4 levels viz., 0, 15, 30 and 45 kg N/ha and 0, 30, 60 and 90 kg P2o5/ha respectively. on growth yield and quality of garden pea cv. Bonneville when compared with control (NoPo). Nitrogen was supp~ed through urea and phosphorus through single superphosphate. A uniform basal dose of 40 kg K20/ha was given to all the experimental plots. Ten plants were selected at random and observations were taken. The plant samples were analysed for different constituents adopting standard procedures. The plant height, number of branches, number of leaves, number of flowers, number of node at which first blossom appeared, ~umber of pods, length of pod, weight of pod, 100 seed weight, shelling percentage, development of seeds, N, P, K composition of plants, N,P,K uptake by plant, yield and quality showed significant response to N and P application. The maximum significant response was observed with application of 45 kg N/ha + 30 kg P2o5/ha. The per cent pod set was unaffected by fertiliza~ion. ""\, In general, there was marked increase in the content of N, P and K in the plant as well as seeds and also uptake of N, P and K with fertilization when compared to control. Increasing levels of N improved these characters but incremental levels of P did not show any influence. Nitrogen content was improved significantly both at flowering and at harvest by N45 which was superior to other levels of N. P content was improved markedly upto N10 at flowering. At harvest levels of N did not exert any influence on P content. N30 improved K uptake both at flowering and at harvest and was at par withN45 and both were superior to N15 N, P and K uptake continu~d till the harvest of the crop but it was decreased towards harvest when compared with that at flowering. N uptake ranged from 30.70 to 82.53 kg/ha and 37.52 to 78.17 kg/ha at flowering and at harvest respectively . K uptake at flowering and at harvest ranged from 9.28 to 27.58 kg/ha at flowering and from 11.09 to 27.72 kg/ha at harvest. Uptake of P ranged from 2.9 to 5.~ kg/ha and from 2.74 to 5.53 kg/ha at flowering and at harvest respectively. Protein content in grain as well as leaves was significantly improved by application of fertilizers over control. Protein content was improved by increasing levels of N but was unaffected by incremental doses of P. The seed protein in general ranged from 22.41 to 31.23%. The highly nutritive leaves will serve as valuable animal fodder. Plant total sugars and reducing sugars were influenced by fertilization over control. Total sugars in seed ranged from 3.08 to 3.64%. Total sugars were unaffected by levels of N and P. Per cent reducing sugars decreased with delay in harvest. Reducing sugars were increased with increasing levels of P while different doses of N did not influence the character. From the results it can inferred that the response to increasing levels of N was due to the low N status of the soil. With the application of P though there was response, it was limited to 30 kg P2o5/ha and this was probably because of moderate level of P in soil. Study of all characters in relation to each other showed that application of 45 kg N/ha along with 30 kg P2o5/ha is optimum to elicit desired growth, yield and quality from garden pea cv. Bonneville grown on sandy loam with irrigation under Hyderabad conditions. |
