| Summary, etc. | The investigations on ‘Fertigation and mulching studies in yard long bean<br/>(Vigna unguiculata var. sesquipedalis (L.) Verdcourt)’ were carried out in the<br/>Department of Olericulture, College of Horticulture, Vellanikkara during January –<br/>May 2014. The study was conducted in the yard long bean variety Vellayani Jyothika<br/>to standardize the fertigation requirement and to assess the relative efficacy of<br/>fertigation and mulching over the conventional method.<br/>The experiment was laid out in strip plot design with two replications. There<br/>was a total of 17 treatments consisting of combinations of two irrigation levels (60<br/>and 80 per cent pan evaporation (Ep) through drip irrigation) and four fertilizer levels<br/>(75, 100 and 125 per cent recommended dose of fertilizer (RDF) and 100 per cent<br/>RDF with water soluble fertilizer) with and without mulching and a control treatment<br/>(channel irrigation once in three days with 100 per cent RDF).<br/>The study revealed that irrigation, mulching and fertilizer levels had<br/>significant effect on vine length. Scheduling of irrigation at 80 per cent Ep resulted in<br/>significantly higher vine length. At higher levels of irrigation (80 per cent Ep) yield<br/>and number of pods per plant were higher whereas, length and weight of pods, and<br/>number of seeds per pod were not influenced by the levels of irrigation. Mulching<br/>significantly influenced yield and yield attributing characters like number of pods per<br/>plant, and length and weight of pods but had no influence on number of seeds per pod<br/>and protein content of pods. Plants receiving 125 per cent RDF resulted in<br/>significantly higher yield and yield attributing characters like number of pods per<br/>plant, number of seeds per pod, length and weight of pods compared to 75 and 100<br/>per cent RDF.<br/>Per se and interaction effects of irrigation, mulching and fertilizer were not<br/>significant with respect to days to first flowering, first fruit set, first harvest, days<br/>from flowering to harvest, number of harvests, duration of the crop and protein<br/>content.<br/>Weed growth in terms of fresh and dry weight was not influenced by levels of<br/>irrigation while mulched plots recorded significantly lower weed growth than the<br/>unmulched plots. Among the fertilizer levels, 125 per cent RDF resulted in higher<br/>weed growth. Organic carbon content, available nitrogen, available phosphorus and<br/>available potassium on 45 DAS and at final harvest were the highest in treatments<br/>receiving 125 per cent RDF whereas, the highest pH and the lowest EC were<br/>recorded in 75 per cent RDF.<br/>Interactions between levels of irrigation, mulching and fertilizer when<br/>considered together, had significant effect on vine length, all yield attributes, weed<br/>growth and all soil parameters. The vine length, yield, yield attributes like length and<br/>weight of pods and soil nutrients were the highest when irrigation was given at 80 per<br/>cent Ep along with mulching and 125 per cent RDF (I1M1F3). This was statistically<br/>on par with the treatment I2M1F3 in which irrigation was limited to 60 per cent Ep. An<br/>increase of 3.4 times was there in yield in the treatments I1M1F3 and I2M1F3 over<br/>conventional channel irrigation at 3 days interval with 100 per cent RDF (control).<br/>The highest BC ratio of 1.83 was obtained for the treatments I1M1F3 and<br/>I2M1F3 (60 and 80 per cent Ep with mulching, 125 per cent RDF). Irrigation at 60 or<br/>80 per cent Ep along with 125 per cent RDF and mulching with white on black<br/>polythene was found to be the best treatments.<br/> |
