Abstract
An experiment entitled “Organic nutrient management in cluster bean (Cyamopsis tetragonoloba L. Taub)” was carried out during summer season of 2018, at Instructional farm, Department of vegetable science, Faculty of Horticulture, Dr. PDKV, Akola. The experiment was laid out in a Randomize block design (RBD) with three replications and twelve treatments. Data on growth (plant height, number of leaves, number of branches and leaf area), pod yield (pod yield plant-1) and, its attributes (pod clusters-1, clusters plant-1, pods plant-1, length and width of pod) and pod quality (protein content %) were recorded.
Morphological characters like plant height, number of leaves plant-1 at all stages of growth were found significantly increased with the application of 100% RDF through (25:50:50kg NPK ha-1) + Rhizobium (25g kg-1 of seed inoculation) +PSB (5kg ha-1 of soil application and 10g kg-1 of seed inoculation) treatment T11 over other treatments. Whereas, treatment T12 i.e. application of Rhizobium (25g kg-1 of seed inoculation) +PSB (5kg ha-1 of soil application and 10gm kg-1 of seed inoculation) has recorded poor growth at all the crop stages over other treatments. Plants that received 100% RDF through (25:50:50kg NPK ha-1) + Rhizobium (25g kg-1 of seed inoculation) +PSB (5kg ha-1 of soil application and 10gm kg-1 of seed inoculation) also showed early flowering, as well as significantly highest pod yield (54.86 q ha-1), while T12 i.e. application of biofertilizers only, recorded lower pod yield (39.38 q ha-1) while, maximum number of pods (84.77 pods plant-1), weight of pods (74.01 g) and highest protein content (22.50 %).observed in treatment T11.
Significantly maximum nitrogen, phosphorus and potassium status in soil after harvest and uptake by plant was found in application of 100% RDF through (25:50:50kg NPK ha-1) + Rhizobium (25g kg-1 of seed inoculation) +PSB (5kg ha-1 of soil application and 10gm kg-1 of seed inoculation) treatment T11.
Highest net returns (RS 66557) and highest B:C ratio (2.54) was recorded with the application of 100% RDF through (25:50:50kg NPK ha-1) + Rhizobium (25g kg-1 of seed inoculation) +PSB (5kg ha-1 of soil application and 10gm kg-1 of seed inoculation) due to highest yield and found to be most remunerative as per the B:C ratio.
These results are, however based on single season data and therefore needs repetition over more seasons is required for confirmation.
Description
The present experiment was carried during summer season of 2018, at Instructional farm, Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola by applying different organic manures alone or in combination with biofertilizers and RDF in Randomized block design (RBD) for better quality and yield of cluster bean.
