Abstract A field experiment entitled “Response of rabi castor (Ricinus communis L.) to irrigation and fertility levels in conjunction with FYM†was conducted on medium black clayey soil of the Instructional Farm, Junagadh Agricultural University, Junagadh during rabi season of the year 2004. The experiment consisting eighteen treatments of all the possible combinations of three levels of irrigation viz., 0.60 IW/CPE ratio (I1), 0.80 IW/CPE ratio (I2) and 1.00 IW/CPE (I3) ratio and three levels of fertilizer viz., 50 % RDF kg ha-1 (F1), 75 % RDF kg ha-1 (F2) and RDF kg ha-1 (F3) along with two levels of FYM viz., 0 t FYM ha-1 (M0) and 10 t FYM ha-1 (M1) were embedded in split plot design with three replication. The results reveled that different levels of irrigation, failed to exert their significant effect on initial and final plant population and plant height recorded at 30 and 60 DAS. Irrigation scheduling at 1.00 IW/CPE ratio (I3) recorded significantly highest growth parameters viz., plant height at 90 DAS and at harvest (114.13 cm and 120.64 cm), number of branches per plant (7.83), days to 50 % flowering (66.55 days) and yield attributes viz., number of spikes per plant (8.83), number of capsules per main spike (101.39) and test weight (349.4), seed yield at first, second and third picking as well as total seed yield (2252 kg ha-1) and stalk yield (4643 kg ha-1) than those in 0.8 and 0.6 IW/CPE ratio. Oil content in seeds remains unaffected due to different levels of irrigation.However, oil yield was significantly higher in irrigation scheduling at 1.0 IW/CPE ratio (1062.94 kg ha-1) than rest of the ratio. Nutrient content and uptake viz., nitrogen content in seed (1.92 %) and stalk (0.816 %), P content in seed (0.343 %) and stalk (0.116 %), N uptake by seed (41.10 kg ha-1) and stalk (38.03 kg ha-1), P uptake by seed (7.45 kg ha-1) and stalk (5.38 kg ha-1) were significantly higher in irrigation at 1.0 IW/CPE ratio than those of 0.8 and 0.6 IW/CPE ratio. The water use efficiency was significantly higher under 0.60 IW/CPE ratio than higher ratio of 0.8 and 1.0 IW/CPE. Maximum net realization of Rs. 20267 ha-1 with 1.45 BCR obtained under 1.0 IW/CPE ratio. The results reveled that different levels of fertility, failed to exert their significant effect on initial and final plant population, plant height at 30 and 60 DAS, length of main spike, seed yield at second picking, oil content, N content by seed, P content by seed and stalk. Application of fertility levels at RDF (F3) significantly higher growth parameters viz., plant height at 90 DAS and at harvest, number of branches per plant (6.50), days to 50 % flowering (62.83), yield attributes viz., number of spikes per plant (7.50), number of capsules per main spike (91.61), test weight (350.4), seed yield at first, and third picking, 912 and 471 kg ha-1 respectively and total seed yield (2148 kg ha-1) as well as stalk yield (4041 kg ha-1) were produced in RDF (F3) than 75 % RDF (F2) and 50 % RDF (F1). Similarly treatment F3 (RDF) recorded significantly higher oil yield (1018.37 kgha-1), water use efficiency (4.372 kgha-1mm-1) and nutrient content and uptake viz., nitrogen content in seed (1.87 %) and stalk (0.793 %), N uptake by seed (38.17 kgha-1) and stalk (32.54 kgha-1), P uptake by seed (6.83 kgha-1) and by stalk (4.61 kgha-1). Maximum net realization of Rs. 17704 ha-1 with 1.19 BCR was secured under RDF than rest of the treatments. The application of different levels of farm yard manure created their significant effect on initial and final plant population, plant height at 30 and 60 DAS, days to 50 % flowering, length of main spike, seed yield at first and second picking, oil content, N content in seed and P content in seed and stalk. Significantly the highest growth parameters viz., plant height at 90 DAS and at harvest, number of branches per plant and yield attributes viz., number of spike per plant (7.57), number of capsule per main spike (91.33) and test weight (339.8) and seed yield at third picking and total seed yield (2200 kg ha-1) and stalk yield (3323 kg ha-1) were recorded by application of 10 t FYM ha-1 than control. Similarly oil yield (1046.10 kgha-1), nutrient content and uptake viz., N content in stalk (0.783 %), N uptake by seed (37.12 kg ha-1) and stalk (26.41 kg ha-1), P uptake by seed (6.59 kg ha-1) and stalk (3.75 kg ha-1) and water use efficiency (4.330 kg ha-1 mm-1) and maximum net realization of Rs. 18552 ha-1 with 1.25 BCR were recorded under application of 10 t FYM ha-1. Interaction effect between irrigation and fertility (stalk yield, N content and uptake and P uptake) and irrigation and FYM (yield at 3rd picking and oil yield) were observed significant. Thus, the present study it could be concluded that the numerically higher production and profit from rabi castor can be secured by application of irrigation at 1.00 IW/CPE ratio and fertilizing the crop with RDF and 10 t FYM in medium clayey soil of South Saurashtra agro climatic zone of Gujarat.
