Abstract:
An investigation entitled, “Effect of irrigation and fertility levels on phenology, partitioning of biomass, yield and quality of radish (<em>Raphanus sativus </em>L.) seed crop”, was carried out at Vegetable Research area of CCS Haryana Agricultural University, Hisar during winter seasons of 2001-02 and 2002-03. The experiment was laid out in split-plot design with three replications. The main plot treatments comprised three irrigation levels viz., i) ID/CPE 0.4, ii) ID/CPE 0.6 and iii) ID/CPE 0.8. The sub-plot treatments consisted of three fertility levels [25% &lt; recommended, as recommended (80kg N + 40kg P<sub>2</sub>O<sub>5</sub> &amp; K<sub>2</sub>O each/ha), 25% &gt; recommended and 50% &gt; recommended]. The plant growth in terms of plant height, number of branches, LAI, LAD, CGR, dry matter accumulation and its partition to different plant parts were positively influenced by the increasing levels of irrigation and fertility during both the years. The different characters (days to flowering in 50% plant, partitioning of dry matter in various parts at 30 DAP and seed vigor index) did not show any marked response to irrigation levels during both the years. The maximum seed yield and significant increase in yield attributing parameters were recorded in plants subjected to ID/CPE 0.8 irrigation level and 25%&gt; recommended fertility level which however, did not differ significantly with 50%&gt; recommended. The NPK contents in plant parts and seed increased with increase in intensity of irrigation &amp; fertility supply. The consumptive use of water also increased but water use efficiency decreased with increasing level of irrigation. On the basis of the findings obtained from two years study, it can be concluded that the highest seed yield with better partitioning of biomass could be insured with highest intensity of irrigation (ID/CPE 0.8) in conjunction with 25%&gt; recommended fertility level.
