dc.description.abstractropped with oil yielding trees under integrated nutrient management practices" was conducted during kharif, 2002 on sandy loam soil at Student's Farm, College of Agriculture, Rajendranagar, Hyderabad to assess the productivity of sunflower intercropped with neem and melia under INM practices. The treatments comprised of three cropping systems viz., sunflower intercropped with neem (ICN), sunflower intercropped with melia (ICM) and sole cropping of sunflower (SC) as main plots and six levels of nitrogen as subplots like control (TI), recommended dose of N 60 kgha (T2), neem GLM @ 5 t/ha + 30 kg N/ha (T3), melia GLM @ 5 tlha + 30 kg Nha (T4), subabul GLM @ 5 tha + 30 kg Nha (T5) and FYM @ 10 t/ha + 30 kg Nha (T6). The experiment was laid out in split plot design with three replications in 5 year old neem and 6 year old melia plantation. The test variety of sunflower was Morden. The experimental site was characterised by semi-arid climate with low organic carbon, available nitrogen and medium in available phosphorus and potassium. The growth parameters of sunflower like leaf area, leaf area index, drymatter production and CGR were siacantly more under sole cropping wlien compared with the intercropping systems at all the growth stages. However, higher drymatter production of 2642 kgha was recorded under sole cropping. All INM practices sigruficantly influenced the growth parameters of sunflower where in subabul GLM @ 5 tfha + 30 kg N/ha resulted in 2914 kg/ha dqmatter production and leaf area index of 0.67 which were found greater. Sole cropping with INM practices produced more growth parameters as compared to intercropping systems. Sole cropping of sunflower with INM practices resulted in higher LT, PAR and TR values with low values of RH and DR as compared to intercropping systems. Yield components of sunflower such as head diameter, head weight, yield per head and test weight were more under solecropping than intercropping system. However, sunflower under neem intercropping had shown better performance as compared to melia intercropping system, All INM practices sigmficantly affected the yield components. However, subabul GLM @ 5 tha + 30 kg Nha produced greater head diameter (9.67 cm), head weight (27.2 g) and test weight (3 1.36 g) over other practices. The seed yield of sunflower under sole cropping (560 kglha) was higher over sunflower intercropped with neem (461 kglha) and melia (3 17 kgha). AU MM practices significantly influenced the seed yield of sunflower. However, Subabul GLM @ 5 tha + 30 kg Nha produced higher yield of 566 kg/ha followed by recommended dose of N 60 kgha (548 kgha), neem GLM @ 5 tha + 30 kg Nha (509 kgha), melia GLM @ 5 tha + 30 kg Nha (490 kgha) and FYM @ 10 t/ha + 30 kg N/ha (457 kgha) over control (107 kg/ha). Higher seed yield of sunflower was obtained under sole cropping with application of subabul GLM @ 5 tlha + 30 kg Nha (710 kg/ha) over all other MM practices. Stalk yield and harvest index were more in sole cropping under all INM practices as compared to intercropping systems. Nitrogen uptake was sidcantly higher under sole cropping (57.8 kgha) as compared to sunflower intercropped with neem (53.6 kg/ha) and melia (38.2 kgha). All MM practices significantly influenced the nitrogen uptake. However, higher uptake of 63.1 kg/ha was obtained with subabul GLM @ 5 t/ha + 30 kg Nha. Among interaction effects, subabul GLM @ 5 t/ha + 30 kg Nha under sole cropping produced increased uptake of nitrogen with 72.4 kglha over all other INM practices. Similarly, P uptake was more under sole cropping whereas K uptake under sunflower intercropped with neem. All INM practices produced significantly higher P and K uptake. Sole cropping of sunflower and INM practices produced more agronomic efficiency and apparent 'N' recovery. However, sole cropping of sunflower under INM practices resulted in increased agronomic efficiency (1 1.81 kg seedkg N applied) and apparent 'N' recovery (97 %) when subabul GLM @ 5 tiha + 30 kg Nha was applied. Signzficantly higher gross returns, net returns and BCR with the values of Rs. 9632, Rs. 3585ha and 0.60, respectively were obtained in intercropping of sunflower with neem over sole cropping and sunflower intercropped with melia. All INM practices recorded ~i~cantly maximum gross returns, net returns and BCR over control. Similarly, sunflower intercropped with neem under INM practices increased gross, net returns and BCR . The results of the study indicated that the productivity of sunflower can be enhanced with INM practices specially with incorporation of subabul GLM @ 5 tma + 30 kg Nha under sole cropping as well as under intercropping with neem.en_US
