Abstract:
A field experiment was carried out at Research cum Instructional Farm, IGKV, Raipur, during kharif season of 2011. The soil of experiment field was ‘Vertisols’. The soil was neutral (pH 7.12) in reaction and medium in fertility having 0.52% organic carbon, low N (205.5 kg ha-1), medium P (17.0 kg ha-1) and high K (345 kg ha-1). The experiment was laid out in split plot design with 3 replications. The main plot consisting of four aromatic rice varieties viz. Jeeraphool, Kasturi Badshah Bhog and Sugandhamati with six organic nutrient management treatments as sub plot viz. T1 (cowdung manure + composted crop residue + Vermicompost), T2 (T1 + BGA + PSB + Azospirillum), T3 (T1 + Rock Phosphate), T4 (T1 + Panchagavya), T5 (T2 + Rock Phosphate + Panchagavya) and T6 (T1 + Neemastra).The results revealed that between Among the four varieties, Sugandhamati recorded significantly higher grain yield (37.74 q ha-1) and followed by Kasturi (33.5 q ha-1) and Badshah Bhog (33.43 q ha-1). Additional organics (BGA+PSB+Azospirillum) over and above of T1 (CDM, CCR and VC) provided a balanced supply of all essential nutrients, which synchronized with crop needs and uptake and thus resulted in significantly higher grain yield (35.99 q ha-1) in T5 (T2 + rockphosphate + panchagavya). Increased in yield over T1 was ranged from 12.3 to as high as 24.8 per cent in T2 and T5 respectively. Interaction between Sugandhamati variety and application of T2 + RP + Panchgavya mixture (T5) recorded higher grain yield of 42.87 q ha‑1 and was significantly superior over all other combination of varieties with organic nutrient management. Significantly the highest straw yield was recorded in Badshah Bhog (96.41 q ha-1) over other varieties. Between the rice aromatic varieties, heaviest panicle was recorded under variety Badshah Bhog (3.45 g) and was found significantly superior over all other varieties. While, Variety Kasturi (20.73 g) recorded significantly highest test weight among all other varieties.
