Description A field experiment was conducted at Coastal Soil Salinity Research Station, Navsari Agricultural University, Danti-Umbharat to study the effect of land configuration and integrated nutrient management on productivity of different varieties of sorghum (rabi) grown on fluventic Ustochrepts during the year 2010-11 and 2011-12. Eighteen treatments, comprising combinations of two land configuration (L1: raised bed and L2: flat bed), three varieties (V1: GJ-38, V2: CSV 216R and V3: BP-53) and three integrated nutrient management (F1: 100 % RDF, F2: 75 % RDF + FYM @ 10 t ha-1and F3: 100 % RDF + FYM @ 10 t ha-1) levels were evaluated in split plot design with four replications. The soil of the experimental field was clayey in texture, low in organic carbon and available nitrogen and high in available phosphorus and potassium.
Plant population (initial and at harvest), days to 50 % flowering and days to maturity were not influenced significantly due to land configuration treatments. Raised bed configuration had significant influence on plant height, dry matter accumulation per plant and leaf area index at 60, 90 DAS and at harvest. However, stem girth was significantly improved under raised bed treatment at harvest. Raised bed treatment also
favorably influenced various yield attributing characters. Sorghum sown on raised bed recorded significantly superior girth of earhead, number of grains per earhead and test weight than that sown in flat beds. Significantly superior grain and stover yields were recorded when sorghum was sown on raised bed as compared to flat bed sowing. The mean grain yield advantage under raised bed sowing was 13.31 per cent over flat bed.
Growth parameters, yield attributes and yield were significantly affected due to different varietal treatments. Variety CSV 216R recorded significantly superior plant height at all the growth stages as well as at harvest. Significantly higher dry matter accumulation per plant at harvest was recorded with variety GJ-38. Varieties GJ-38 and CSV 216R recorded significantly less days to 50 % flowering and days to maturity than BP-53. While, stem girth was significantly superior in variety BP-53. Variety GJ-38 recorded significantly higher leaf area index but remain at par with variety BP-53. Variety GJ-38 recorded significantly higher length of earhead, number of grains per earhead, grain (3420 kg ha-1) and stover (8481 kg ha-1) yields.
INM levels also showed discernible influence on growth characters, yield attributes and yield of sorghum. Application of 100 % recommended dose of fertilizer (80-40-00 NPK kg ha-1) + FYM @ 10 t ha-1 was found good and remarkably improved plant growth characters like, plant height (90 DAS and at harvest), dry matter accumulation plant-1 (60, 90 DAS and at harvest), stem girth and LAI (60 DAS), grains per earhead, grain yield and stover yield. The magnitude of increase in grain yield was 12.13 per cent over 100 % RDF and 15.64 per cent over 75 % RDF alongwith FYM @ 10 t ha-1, respectively.
Both variety and INM treatments remarkably influenced the plant nutrient uptake and protein yield. Variety GJ-38 showed higher uptake of plant nutrients and protein yield than CSV 216R and BP-53. Similarly, application of 100 % RDF alongwith FYM @ 10 t ha-1 considerably improved the nutrient uptake by sorghum over 100 % RDF and 75 % RDF alongwith FYM @ 10 t ha-1. Soil available N and P content after crop harvest were significantly higher under INM treatment 100 % RDF + FYM @ 10 t ha-1.
So far as economic assessment is concerned, maximum net return of ₹ 47002 ha-1 and benefit : cost ratio of 2.43 were accrued under raised bed treatment. Sowing of sorghum variety GJ-38 accrued ₹ 48299 ha-1 net realization and benefit : cost ratio of 2.49. Application of 100 % RDF + FYM @ 10 t ha-1 recorded maximum net realization of ₹ 47800 ha-1 which was followed by treatment 100 % RDF i.e., ₹ 42576 ha-1 while reverse trend was observed in case of benefit:cost ratio. Sorghum fertilized with 100 % RDF alongwith FYM @ 10 t ha-1 increased net realization by 10.93 and 25.73 per cent over 100 % RDF and 75 % RDF alongwith FYM @ 10 t ha-1, respectively.
The interaction between land configuration, variety and INM was found to be non-significant for all parameters studied.
Based on the findings of two years experimentation, it can be concluded for achieving higher yield and net income from sorghum grown during rabi season on coastal salt affected soils with better soil quality, it is essential to sow sorghum variety GJ-38 on raised bed and fertilized the crop @ 100 % RDF + 10 t FYM ha-1
