    A field experiment was conducted during rabi 200-2001 on sandy loam soils in Tirupati Campus of the Acharya N .G. Ranga Agricultural University to study the effect of pre and post emergence herbicides on weed control. growth and yield of groundnut. The experiment was laid out in a rando~nised block design with three replications. There were twelve treatments viz.. unweeded control. intercultivation at 20 DAS with star weeder, intercultivation at 20 DAS with stanveeder followed by (fb) hand weeding at 40 DAS, two hand weedings (20 and 40 DAS) pre-plant incorporation of fluchloralin @ 1.5 kg ha", preemergence application of pendiinethalin @ 1.5 kg ha-', post emergence application of i~nazethapyr 75 g a.i. ha" at 20 DAS, fluchloralin flo imazethappr. pendimethalin fb iinazethapyr, fluchloralin fb hand weeding at 40 DAS, pendiinethalin fb hand weeding at 40 DAS and i~nazethapyr fb hand weeding at 40 DAS. Seventeen weed species were identified and they belonged to 10 families of which Cyperus rotundw L being predominant. Ainong the weed coiltrol treatments pre emergence application of pendimethalin @ 1.5 kg a.i. ham' fb irnazethapyr @ 75 g a.i. ha' at 20 DAS, pre plant incorporation of flucllloralin @ 15 kg a.i. ha-' fb irnazethapyr @ 75 g a.i ha-' at 20 DAS and hand weeding twice (20 and 40 DAS) were effective against all types of weeds and also gave higher weed control efficiency. Plant height, LA1 and dry matter production were I~igl~er with pendiinethal in fb i~nazethapyr which was on par with fluchloralin fb imazethapyr and hand weeding twice (20 and 40 DAS) where as unweeded courrol. intercultivation alone, imazethapyr alone had lower values for all t hr: above characters. The number of nodules per plant and nodule dry weight was highest in hand weeding twice which was on par with pendirnethalin fb imazethapyr and fluchloralin fi imazethapyr. The number of pegs per plant, Total number of pods per plant, filled pods per plant , 100 pod weight, 100 kernel weight, shelling percentage were lvore with pre emergence application of pendiinethalin fb ilnazethapyr at 20 DAS and was comparable with fluchloralin fb imazethapyr and hand weeding twicr (20 and 40 DAS). Pre-emergence application of pendimethal in fb ilnazet hapyr at 20 \)AS gave higher pod (2162 kg ha-') and haul~n (3860 Kg ha-') yield and was colnparable with fluchloralin fb imazethapyr and hand weeding t~vice. Net returns (Rs. 3075 ha-') and benefit cost ratio (2.5) were higher wit11 fluchloralin @ 1.5 kg a.i. ha-' as PPI ib irnazethapyr @ 75 g a.i. ha-' at 20 DAS. The above results revealed that pre-plant incorporation of fl~ichlural in @ 1.5 kg a.i. ha" fb imazethapyr @ 75 g a.i. ha" at 20 DAS was found be effective weed management practice, considering the econonlic rerurns, eventhough pendimethalin fb imazethapyr gave equally higher yield in irri_eated groundnut during rabi on sandy loam soiis.

    EFFECT OF PRECEDING CROPS AND FYM ON THE YIELD AND QUALITY OF ORIENTAL TOBACCO
    (Acharya N G Ranga Agricultural University, Guntur, 2002) RAVI, V; KOTESWARA RAO, D.S.
    Field experiment entitIed "Effect of preceding crops and FYM on the yield and quality of oriental tobacco" was carried out during rabi, 2000 on farmer's field of Nallpareddigaripalli village, Chinnagottigallu mandal, Chittoor district of Andhra Predesh, with a view to find out suitable preceding crop and FYM level. Three preceding crops viz., gingelly, greegram, groundnut and fallow and two manurial levels viz., 0 (control) and 4 t ham' of FYM were tried in a randomized block design with factorial concept and replicated thrice. The soil was of sandy loam in texture with pH of 6.8, Iow in available nitrogen (196 kg ha-') medium in available phosphorus (31 kg ha " ) and available potassium (177 kg ha") Preceding crops and FYM as well as their interaction has significantly influenced the plant growth characters, yield, quality and economic returns of oriental tobacco. All the growth characters were significantly influenced by preceding crops. Among different preceding crops, groundnut has resulted in taller plants, more number of leaves plant-', higher LAI and higher dry matter production of tobacco, Reduced growth stature of tobacco was associated with gingelly as preceding crop. Maximum and minimum green leaf and cured leaf yields of tobacco were obtained in the crop raised after groundnut and gingelly, respectively. Groundnut as preceding crop has increased nicotine content, chloride content and net returns of tobacco, where as total sugars were found reduced. On the other hand, highest total sugar content and lowest nicotine and chloride content were observed in tobacco preceded by gingelly. Net returns were also the lowest with gingelly - tobacco sequence. Application of FYM has increased all the growth characters of tobacco. Significantly taller plants, more number of leaves plant-', higher LA1 and drymatter production were observed in the crop received 4 t ha-' of FYM. Significantly higher green leaf and cured leaf yields of tobacco were observed with the application of FYM @ 4 t ha-'. Quality characters viz.. nicotine content, and chloride content increased, while the total sugars decreased, with application of FYM. Gross as well as net returns and benefit cost ratio were higher with the application of FYM @ 4 t ha". The interaction of preceding crops and FYM has significantly influenced the plant growth characters, yield, quality and economic returns of tobacco. Tobacco preceded by groundnut and manured with FYM @ 4 t ha'' has resulted in taller plants, more number of leaves plant-', higher LAI, and drymatter production. Similar trend was observed with regard to green leaf and cured leaf yields, nicotine content, chloride content, gross returns and net returns. Tobacco preceded by gingelly and did not receive any manure has produced the lowest growth characters, green and cured leaf yields and poor economic returns. It can be inferred form the above study that oriental tobacco receiving FYM preceded by legumes like groundnut or greengram has resulted in higher yield and net returns. Exhaustive crops like gingelly as preceding crop resulted in lower yield and net returns.

    (Acharya N G Ranga Agricultural University, Guntur, 2001) SUNITHA, N; REDDEPPA REDDY, M
    A field experiment was conducted during rabi 2000, on sandy loam soils of Tirupati campus (Southern ago-climatic zone of A.P) of Acharya N.G.Ranga Agricultural university, to study the effect of different integrated nitrogen management practices on growth and yield of finger milIet and to identifjr the most productive and economic integrated nitrogen management practices for irrigated finger millet. The study was laid out in randornised block design, replicated thrice with fourteen treatments mo (TI), Azotobactev alone (T2), FNlO0 (TI), FN75 + FYM N25 (T4), FN75 + GLM N25 (TS), FN75 + Azotobucter (T6), FNSO + FYM NS0 (T7), FN50 + GLM N5() (Ts), FNso + Azotobacter (T9), FNSo + FYM Nz5 + Azotobacter (Tlo), FNSo + GLM Nz5 + Azotobucter (TI,), FNS0 + FYM N25 + GLM N25 (T12), FNls + FYM N5, + Azotobncter (TI3), FNzs + GLM NSo + Azolobacter (TI4)]. Organic sources of N (FYM and GLM) were incorporated 15 days before transplanting. Azotobocter (1 kg ham1) was inoculated through seedling root dipping in sluny (prepared by mixing Azotobacter, FYM and water in 1 :5: 10 ratio) for 15 minutes prior to transplanting. The test variety was Sapthagiri. Integrated nitrogen management practices significantly influenced the growth characters (viz., plant height, leaf area index, dry matter production and number of tillers mq2) yield attributes (number of productive tillers mm2, fingers ear-', ear length, ear weight and grain weight), yield (grain and straw), nitrogen uptake of finger millet and post harvest soil fertility status. Application of 100% N through fertilizer (T3) has resulted in production of tallest plants, highest number of tillers rn'2, the largest leaf area index, highest total dry matter production, but it was on par with 75% fertilizer N + 25% N through FYM (T4) and 75% fertilizer N + 25% N through GLM (T5) at all the stages of crop growth. Growth characters were found to be the lowest with control (TI) at all the stages of crop growth. The highest values of crop growth rate and net assimilation rate were recorded with 100% N through fertilizer (T3), 75% fertilizer N + 25% N through FYM (T4), 75% fertilizer N + 25% N through GLM (T5), where as the lowest were observed in the control (T1) plot. Earliness in reaching 50% flowering and maturity was registered with nonsupply of nitrogen through any source (TI) and Asofobacter inoculation (T2). Flowering and maturity were most delayed in the crop received 100% fertilizer N 03). . Regarding the yield attributes, number of productive tillers mm2, fingers ear", ear weight, grain weight were found to be the highest with 100% N through fertilizer (T3), which were however, comparable with 75% fertilizer N + 25% N through FYM (T4) and 75% fertilizer N + 25% N through GLM (T5). All the yield attributes were at the lowest with control (TI). Supply of 100% N through fertilizer (T3) has resulted in the highest grain yield, which was however at par with 75% fertilizer N + 25% N through FYM (T4) as well as 75% fertilizer N + 25% N through GLM (TS). The next best treatments were 50% fertilizer N + 25% N through FYM + 25% N through GLM (Tlz), 50% fertilizer N + 50% N through FYM (T7), 50% fertilizer N + 50% N through GLM (Ts), which were on par with each other. The lowest graili yield was recorded in the control (TI) plot. Straw yield of 100% N through fertilizer (T3), 75% fertilizer N + 25% N through FYM (T4), 75% fertilizer N + 25% N though GLM (T5) were comparable and were significantly superiol- to rest of the treatments. The lowest straw yield was observed with control (TI). The highest and lowest values of harvest index were noticed with 100% fertilizer N (T3) and non-supply of N through any source (TI), respectively. Uptake of nitrogen was found to be the highest with 100% N through fertilizer (T3), which was however, on par with 75% fertilizer N + 25% N through FYM (T4) and 75% fertilizer N + 25% N through GLM (Tj) at all the stages of crop growth. The lowest nitrogen uptake was resi1.1ted with control (TI). Post harvest soil fertility status was found to be significantly improved with Asofobacter + 25% fertilizer N + 50% N through GLM (TI4), Azotobacter + 25% fertilizer N + 50% N through FYM (TL3) as well as with 50% fertilizer N + 50% N through GLM (T8) and 50% fertilizer N -+- 50% N though FYM (T7). In conclusion, the investigation has revealed that higher grain yield of finger millet as well as net profit could be obtained with 100% recommended N through fertilizer to irrigated finger millet on sandy loam soils of Tirupati, Recommended dose of nitrogen could be reduced upto 25% without any significant reduction in yield as well as net returns, when applied jn combination with organic sources as FYM or GLM, besides improvement in the soil fertility status

    EFFECT OF NITROGEN AND PHOSPHORUS IN COMBINATION WITH BI0-FERTILIZERS ON GROWTH AND YIELD OF SOY BEAN (Glycine max (L.) Merrill)
    (Acharya N G Ranga Agricultural University, Guntur, 2001) SRINIVAS, VISWARAJU; REDDEPPA REDDY, M
    A fieId experiment was conducted during rabi, 1999, on sandy loam soils at Tirupaci campus of Acharya N.G. Ranga Agricultural university, to study the effect of nitrogen and phosphorus in combination with bio-fertilizers on growth and yield of soybean. The treatments comprised of combinations of individual as well as dual inocu l at ion of Bradyrhizobium japonicum and Phosphobacterium either alone or in corn binat ion with 50% ,75 % and 100% level of recommended dose of nitrogen, phosphorus or both, recommended dose of nitrogen and phosphorus and uninoculated control. These were rested in a randomized block design and replicated thrice. Brdyrhizobium japonicum (500 g ha-') was seed inoculated and Phosphobacterium (2 kg ha- I) was mixed with well decomposed farm yard manure along with sand (1 :5:5) and applied in seed rows at the time of sowing. Different nitrogen and phosphorus management practices have significantly influenced the growth characters, (Viz., plant height, leaf area index, total dry matter production and number as well as dry weight of nodules), yield attributes, (pod length, number of pods per plant, number of seeds per pod and 100 seed weight), yield, (seed and stalk), nutrient uptake and post harvest soil fertility status. .'.V. Application of bio-fertilizers along with recommended dose of nitrogen and phosphorus resulted in higher stature of growth pameters than with application of recomrnended dose of nitrogen and phosphorus. Dual inoculation in combination with recommended dose of nitrogen and phosphorus has resulted in production of the tallest plants, the largest leaf area index and the highest total dry matter production, but it was on par. with Phosphobacteriurn inoculation along with recommended dose of phosphorus, at all the stages of crop growth, except 25 DAS in case of leaf area index and total dry mattes production. Plant height, leaf area index and total dry matter production of soybean were found to be the lowest with control at all the states of crop growth. Number of nodules and nodule dry weight plant were found to be the highest with dual inoculation coupled with recommended dose of nitrogen and phosphorus which was however, on par with Rhizobiurn inoculation in combination with recommended dose of nitrogen, at all the stages of crop growth except at 50 DAS in case of nodule dry weight plant -I. The least number and dry weight of nodules plant -I were observed with control. Dual inoculation coupled with recommended dose of nitrogen and phosphorus has resulted in the longest pods, more number of pods per plant and number of seeds per pod, which were however, on par with Phusphobacterium inoculation along with recommended dose of phosphoms. The length of pods, number of pods per plant and number of seeds per pod were at the lowest with control. The highest 100 seed weight was observed with dual inoculation in combination with recommended dose of nitrogen and phosphorus, while the lowest 100 seed weight was noticed with control. Dual inoculation in combination with recommended dose of nitrogen and .phosphorus has resulted in the highest seed yield, which was however in parity with Phosphobacrerium inoculation along with recommended dose of phosphorus. Rhizobium inoculation in combination with recomrnended dose of nitrogen was comparable with recornmended dose of nitrogen and phosphorus and these were the next best treatments. The lowest seed yield was recorded in control, Stalk yield of dual inoculation coupled with recommended dose of nitrogen and phosphorus and Phosphobacterium inoculation in combination with recommended dose of phospl-iorus were comparable, which were significantly superior to rest of the treatments. The lowest stalk yield was observed with control. Maximum and minimum values of harvest index were noticed with dual inoculation along with recommended dose of nitrogen and phosphorus and control, respectively. uptake of nitrogen and phosphorus were found to be the highest with dual inoculation coupled with recommended dose of nitrogen and phosphorus, which was comparable with to Phosphobacterium inocuIa tion along w i ti1 recommended dose of phosphorus, at 50 DAS and harvest. The lowest uptake of nitrogen and phosphorus was observed with contro t. Post harvest soil available nitrogen and phosphorus were found to be significantly improved with dual inoculation as well as Phosphobacteriurn inoculation along with recommended dose of nitrogen and phosphorus. Maximum gross returns, net returns and benefit-cost ratio were obtained with dual inoculation along with recommended dose of nitrogen and phosphorus, followed by Phosphobacterium inoculation in combination with recommended dose of phosphorus. In conclusion, the investigation revealed that the highest yield as well as net profit could be obtained with application of both the bio-fertilizers along with recommended dose of nirrogen and phosphorus in soybean on sandy loam soils of Tirupati. Recommended dose of nitrogen and phosphorus could be reduced upto 25 per cent with out any significant reduction in seed yield as well as net returns, when applied in combination with both rhe bio-fertilizers.
