Self-sustainable energy sources are likely to hold the key to economic development of India in future. It is mandatory to seriously implement bio-energy development programmes as a part of environmental sustainability in the form of clean development mechanism. Publicity in an excessive way triggered a lot of investment in Jatropha but the return is not so promising. A small step to assess its potential by applying irrigation and fertilizer were taken up and for that investigations were conducted at the seed production farm Achhaliya under Navsari Agricultural University, Navsari, during 2009 and 2010 to study the “Effect of irrigation and fertilizer on growth and yield of Jatropha curcas L. under South Gujarat conditions”. The soil of the experimental plots was clayey in texture (17.65 %, 32.45 % and 49.90 % sand, silt and clay), low in available nitrogen 97.56 Kg/ha N, 47.70 Kg/ha P2O5 (phosphorus) and 159.28 Kg/ha K2O (potassium). The experiment was laid out in split plot design with four irrigation schedules on critical growth stages viz., 0.4 IW/CPE ratio (I1), 0.6 IW/CPE ratio (I2), 0.8 IW/CPE ratio (I3) and 1.0 IW/CPE ratio (I4) and four levels of fertilizer F0 (N0 P0 K0 g/plant), F1 (N20 P40 K20 g/plant), F2 (N40 P80 K40 g/plant) and F3 (N60 P120 K60 g/plant) replicated thrice. The growth and yield attributes of Jatropha were significantly influenced by the treatment I2 and showed highly significant correlation with seed yield. Amongst the various irrigation schedules, treatment I2 produced significantly the maximum seed yield (837.58 Kg/ha and 1147.75 Kg/ha), Stover yield (7968.75 Kg/ha and 11981.58 Kg/ha) with maximum net realization Rs 9426 per hectare giving net BCR value of 1.58.The consumptive use of water was 527 mm (average of two years) and water use efficiency obtained was 2.81 Kg/ha-mm of water (average of two years). Irrigation schedules failed to affect N, P and K content of different plant parts of Jatropha but affected significantly its uptake by different plant components of Jatropha. It was also observed that the Jatropha crop responded significantly to fertilizer in terms of maximum growth and yield attributes, seed yield, Stover yield, as well as oil yield. Treatments F3 (N60 P120 K60 g/plant) produced significantly maximum seed yield (1409.17 Kg/ha and 1891.25 Kg/ha), Stover yield (11006.08 Kg/ha and 15970.92 Kg/ha) in 2009 and 2010, respectively, with maximum realization of Rs10062.00 giving net BCR value of 0.55. The consumptive use of water was 452 mm (average of two years) and water use efficiency 2.70 Kg/ha-mm of water (average of two years) The N, P and K contents of different plant parts of Jatropha was uninfluenced due to irrigation schedule but was affected significantly owing to application of different levels of fertilizer. The nutrient uptake by leaves, stem, shell and seed was significantly affected by irrigation schedule, levels of fertilizer and interactions between irrigation and fertilizer. In case of major nutrients viz., N, P and K uptake by leaves, stem, shell and seed, the treatments I2 maintained its superiority over rest of the treatments. Similarly, among the fertilizer levels, F3 showed higher removal of N, P and K by different plant parts of Jatropha compared to rest of the treatments. The treatment combination I2F3 recorded significantly higher uptake of N, P and K as compared to the remaining treatment combinations. In case of quality characters viz., oil percent and oil yield was influenced by irrigation, fertilizer and interactions between irrigation and fertilizer. Irrigation schedule I2 showed its superiority over rest of the treatments and recorded the highest oil percent (32.34 and 32.72) and oil yield (281 Kg/ha and 391 Kg/ha) in the year 2009 and 2010, respectively. Similarly, the fertilizer levels F3 (N60 P120 K60 g/plant) recorded significantly the highest oil percent (33.73 and 34.42) and oil yield (578 Kg/ha and 654 Kg/ha) in the year 2009 and 2010, respectively. The treatment combination I2F3 recorded significantly higher oil per cent (34.80 and 35.73) and oil yield (589 Kg/ha and 779 Kg/ha) as compared to the remaining treatment combinations. In respect to biological properties of soils, the higher level of fertilizer increased the soil organic carbon as compared to control. The chemical properties viz., pH and EC were not affected due to irrigation schedule but affected due to levels of fertilizer. Treatment F3 recorded significantly lower pH and EC in both the years as compared to rest of the treatments. In case of soil fertility, only the available N was influenced due to irrigation schedule, fertilizer levels and interactions between irrigation and fertilizer. The soil P2O5 and K2O were significantly increased with treatment F3 in comparison to rest of the treatments. Based on the above findings, it can be said that the Jatropha var, (local) required (13) irrigations based on IW/CPE ratios, over and above one common irrigation required initially after application of fertilizer to different plots as per the treatments. The fertilizer treatment F3 (N60 P120 K60 g/plant) was found most economical dose for getting optimum yield in vertisols of South Gujarat. |
