CROP INTENSIFICATION IN RAINFED ALFISOLS
(Acharya N G Ranga Agricultural University, Guntur, 2003) SAMPATH KUMAR, DADIGIRI; SRINIVASULU REDDY, D
A study on "rop intensification in rainfed alfisols" was takenup at Agricultural Research Station (ANGRAU), Kadiri (Scarce rainfall zone of Andhra Pradesh), through two experiments, simultaneously for two consecutive years during 2000 and 2001, one with the aim of establishing an efficient groundnut based intercropping system and another to study the possibility and identifying efficient groundnut based sequence cropping system for enhancing the crobping intensity to the extent as maximum as possible in rainfed alfisols. I. \ In the first experiment, groundnut sbwn at 30 cm spacing was intercropped with pigeonpea, castor, sorghum, pearlmillet, sunflower, sesame, greengram and soybean at 7:1, 7:1, 6:2, 6:2, 3:1, 3:1, 3:l and 3:l row proportions, respectively. All the treatments were tried in additive series version of intercropping, keeping the population of base crop (groundnut) in all the treatments at 100 per cent of its sole crop (3, 33, 333 plants ha"), by adjusting the intra-row spacing. In second experiment, groundnut was grown during kharifin all treatments and immediately after harvesting of groundnut, seven shd duration crops viz., greengram, cowpea, sunflower, horsegram, clusterbean, pearlmillet and sorghum were raised in each treatment during rabi. Both the experiments were conducted in randomized block design and replicated thrice, Intercropping of groundnut with pearlmillet or sorghum registered the highest plant height of groundnut, during both the years of study. Groundnut + pigeonpea system resulted in the shortest groundnut plants. Number of leaves per plant, LAI, dry matter production (kg ha- ) and number of root nodules per plant of groundnut were higher with pigeonpea as intercrop, closely followed by intercropping with castor. All these growth parameters were at their lowest with pearlmillet and sorghum as intercrops. Yield attributes of groundnut viz., number of branches, flowers, pegs, total and filled pods per plant; hundred pod weight, hundred kernel weight, I shelling percentage and sound.mature kernel percentage of groundnut were found to be the highest with gi-oundnut + pigeonpea intercropping system, which were however, co6arable with groundnut + castor system. All these attributes were at their lowest, when groundnut was intercropped with either 4' pearlmillet or sorghu,p. I Pod yield (pooled mean) of groundnut was the highest with groundnut. + pigeonpea, which was on par with groundnut + castor. The lowest pod yield of groundnut was realized with pearlmillet or sorghum as intercrops. Haulm yield of groundnut hllowed the same trend of pod yield. Groundnut pod equivalent yield (pooled mean) of intercropping system was the highest with groundnut + castor, which was coinpirable with groundnut + ..pigeonpea. Groundnut + soybean system recorded the lowest groundnut pod equivalent yield, which was significantly inferior to other intercropping systems, except with groundnut + greengram. Efficiency evaluation indices viz., LER, ATER and SLER were found to be maximum with groundnut + castor followed by groundnut + pigeonpea, while groundnut intercropped with greengram resulted in the ,lowest values of these indices. The net gain of soil available nitrogen was the highest with groundnut -k pigeonpea system, while the lowest net gain was associated with groundnut + sorghum. The highest and lowest net gain of soil available P2O5 was recorded with groundnut + pearlmillet and groundnut + sesame intercropping systeins, respectively. The net gain of soil available K20 was the highest with groundnut + soybean system, while the lowest net gain was associated with groundnut + sorghum intercropping system. Net returns and benefit cost ratio were the highest with groundnut + castor system, which were comparable with groundnut + pigeonpea, while the lowest net returns and benefit cost ratio were registered with groundnut + soybean. The highest monetary advantage was realised with groundnut + castor intercropping system, which was significantly superior to all other + intercropping systems, while ihi lowest was associated with grounclnut + greengram system. The highest dry matter production, econoinic yield (groundnut pod equivalent yield) and the econon~ic returns of different sequence crops tried after 1cl.larif groundnut was maximum with clusterbean, which were significantly superior to rest of the crops, while sorghum as the sequence crop recorded all the above parameters at their lowest level, with negative net returns.

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).

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.
