    STUDIES ON GROWTH AND YIELD OF DIFFERENT CASTOR HYBRIDS AT VARYING NITROGEN LEVELS
    (Acharya N.G. Ranga Agricultural University, 2018) BHARGAVI, B; SREE REKHA, M
    A field experiment was conducted on clay soils of the Agricultural College Farm, Bapatla to Studies on growth and yield of different castor hybrids at varying nitrogen levels during kharif, 2017-18 under rainfed conditions and the treatment combination comprised three hybrids (V1 : PCH 111, V2 : GCH 4 and V3 : Western Maruthi ) and four nitrogen levels (N1 : 60 kg ha-1, N2 : 80 kg ha-1, N3 : 100 kg ha-1 and N4 : 120 kg ha-1) evaluated in a Randomized Block Design with factorial concept and replicated thrice. Plant height of castor was significantly affected by different castor hybrids at 60, 90 DAS and at harvest. The maximum plant height was attained with hybrid PCH 111 (V1) which was significantly superior to GCH 4 (V2) but was found at par with Western Maruthi (V3). However, significantly the tallest plants were produced with GCH 4 (V2) at 60 DAS compared to other hybrids. Tallest plants were produced with the application of 120 kg N ha-1 (N4) and was significantly superior to 60 kg N ha-1(N1), however, at 90 DAS and at harvest, the maximum plant height was recorded with the application of 120 kg N ha- 1(N4) which exhibit significant superiority over other N levels (60 (N1) and 80 (N2) kg N ha-1), but was found on par with the application of 100 kg N ha-1(N3). The highest drymatter accumulation observed with the hybrid PCH 111 (V1) was significantly greater than GCH 4 (V2) and Western Maruthi (V3) at 90 DAS and at harvest. However, at 60 DAS maximum drymatter production was registered under GCH 4 (V2) compared to other hybrids. Application of 120 kg N ha-1(N4) at 60 and 90 DAS significantly enhanced the drymatter accumulation over 60 kg N ha-1 (N1). At harvest, maximum drymatter accumulation was attained with 120 kg N ha-1(N4) but it was on a par with 100 kg N ha-1(N3), and xv was significantly superior to 60 kg N ha-1(N1) and 80 kg N ha-1(N2). The interaction effect was significant at 90 DAS, where V1N4 treatment combination displayed results best was on a par indicative with the V1N3 and V3N4 which were and it was significantly superior to other treatment combinations. Number of days taken to maturity were significantly less in castor hybrid GCH 4(V2) compared to other two hybrids. Days to maturity were earlier with the application of 60 kg N ha-1(N1) and 80 kg N ha-1(N2) than other levels of nitrogen tested. Significantly higher number of spikes plant-1 and increased primary spike length was noticed with GCH 4 (V2), which was however, superior to Western Maruthi (V3) and both were on a par with PCH 111(V1). With respect to number of capsules primary spike-1 and weight of primary spike, hybrid PCH 111 (V1) exhibited significantly the highest over rest of the two hybrids. The number of spikes plant-1 and weight of spike were significantly higher with the treatment that received 120 kg N ha-1(N4) over 60 kg N ha-1(N1). The highest number of capsules spike-1were recorded with 120 kg N ha-1(N4), which was significantly superior to rest of the N levels. Spike length, did not significantly respond to application of nitrogen but exhibited increasing trend with increase in nitrogen application. The total bean yield of castor from all the three pickings (primary, secondary and teritiary spikes) was obtained maximum, in PCH 111 (V1) followed by GCH 4 (V2) which was significantly superior to Western Maruthi(V3). Interaction was significant between hybrids and nitrogen levels for castor bean yield. Maximum bean yield was obtained with V1N4 (PCH 111 @ 120 kg N ha-1) which was on par with V1N3 (PCH 111 @ 100 kg N ha-1) and V2N4 (GCH 4 with 120 kg N ha-1). Significantly highest stalk yield of castor was registered in PCH 111(V1) which was superior to GCH 4 (V2) and found statistically on par with Western Maruthi (V3). Harvest index was significantly influenced by hybrids and was highest in GCH 4 (V2), which was superior to other hybrids. Castor hybrids sown @ 120 kg N ha-1 (N4) produced the maximum bean and stalk yield which was significantly superior to 60 kg N ha-1 (N1) and 80 kg N ha-1(N2). However it was on a par with 100 kg N ha-1(N3). Harvest index response to N levels was non-significant. The maximum nitrogen uptake by crop at 90 DAS and at harvest in PCH 111(V1) was significantly higher to GCH 4 (V2) but was on a par with Western Maruthi(V3). However, N uptake by seed at harvest in PCH 111 (V1) was significantly superior to Western Maruthi (V3) and comparable with GCH 4(V2). Significantly, higher nutrient uptake was noticed in the treatment that received 120 kg N ha-1(N4) at 60, 90 and at harvest (stalk +seed) when compared with 60 kg N ha-1(N1) and 80 kg N ha-1(N2) but was on a par with 100 kg N ha-1(N3). The highest net returns and return per rupee invested was recorded with the application of 120 kg N ha-1 (N4) with PCH 111 (V1) over all other treatment combinations. xvi Overall, the study indicated that castor hybrids PCH 111(V1) and GCH 4 (V2) performed better than Western Maruthi(V3). Response to nitrogen was linear till 120 kg N ha-1(N4) but was found on par with 100 kg N ha-1(N3) during kharif in Krishna agroclimatic zone of Andhra Pradesh.

    WEED MANAGEMENT IN TRANSPLANTED FINGER MILLET (Eleusine coracana (L.) Gaertn)
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, 2014) BHARGAVI, B; SUNITHA, N
    A field experiment was conducted at S.V. Agricultural College Farm, Tirupati campus of Acharya N.G. Ranga Agricultural University of Andhra Pradesh, during kharif, 2013, to identify the most economic and viable weed management practice in transplanted finger millet. The present investigation was laid out in a randomized block design with three replications. There were ten treatments viz., pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 (T1), pre-emergence application of oxadiargyl @ 75 g a.i ha-1 (T2), pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb hand weeding at 20 DAT (T3), pre-emergence application of oxadiargyl @ 75 g a.i ha-1 fb hand weeding at 20 DAT (T4), pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb post-emergence application of azimsulfuron @ 20 g a.i ha-1 at 20 DAT (T5), pre-emergence application of oxadiargyl @ 75 g a.i ha-1 fb post-emergence application of azimsulfuron @ 20 g a.i ha-1 at 20 DAT (T6), pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb post-emergence application of chlorimuron-ethyl @ 5 g a.i ha-1 at 20 DAT (T7), pre-emergence application of oxadiargyl @ 75 g a.i ha-1 fb post-emergence application of chlorimuron-ethyl @ 5 g a.i ha-1 at 20 DAT (T8), hand weeding twice at 20 and 40 DAT (T9) and unweeded check (T10). The test variety of finger millet was Vakula. Weed flora observed in the experimental field consisted of five species of grasses, two species of sedges and seven species of broad leaved weeds. Among the weed management practices tried, pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb azimsulfuron @ 20 g a.i ha-1 applied at 20 DAT (T5) resulted in the lowest density and dry weight of total weeds with higher weed control efficiency, which was however comparable with pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb hand weeding at 20 DAT (T3). Pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 was effective for the control of grasses and broad leaved weeds whereas azimsulfuron @ 20 g a.i ha-1 applied at 20 DAT was effective against sedges and broad leaved weeds in transplanted finger millet. Preemergence application of oxadiargyl @ 75 g a.i ha-1 supplemented with hand weeding at 20 DAT (T4) or azimsulfuron @ 20 g a.i ha-1 applied at 20 DAT (T6) or chlorimuron-ethyl @ 5 g a.i ha-1 applied at 20 DAT (T8) performance was comparable in reducing the density and dry weight of weeds. Pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 (T1) or oxadiargyl @ 75 g a.i ha-1 alone (T2) recorded the higher density and dry weight of total weeds with lesser weed control efficiency. The highest density and dry weight of weeds was associated with unweeded check. Pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb azimsulfuron @ 20 g a.i ha-1 applied at 20 DAT (T5) significantly improved the growth parameters viz., plant height, leaf area index, total number of tillers m-2, dry matter production and yield attributes viz., productive tillers m-2, fingers ear-1, ear weight and test weight. All these parameters were comparable with pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb hand weeding at 20 DAT (T3). The highest grain and straw yields of finger millet were recorded with preemergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb azimsulfuron @ 20 g a.i ha1 applied at 20 DAT (T5), however on par with pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb hand weeding at 20 DAT (T3). The grain yield was reduced by 47 per cent in unweeded check compared to the best weed management practice i.e pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb azimsulfuron @ 20 g a.i ha-1 applied at 20 DAT (T5). The highest gross and net returns were realized with pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb azimsulfuron @ 20 g a.i ha-1 applied at 20 DAT (T5), which were comparable with pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb hand weeding at 20 DAT (T3). However, the highest benefit-cost ratio was registered with the former weed management practice (T5). In conclusion, the present study revealed that pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb azimsulfuron @ 20 g a.i ha-1 applied at 20 DAT effectively suppressed the broad spectrum of weeds, provided season long weed control and resulted in the highest grain yield and economic returns of transplanted finger millet, which was however comparable with pre-emergence application of oxyflourfen @ 0.1 kg a.i ha-1 fb hand weeding at 20 DAT. The choice of weed management strategy in transplanted finger millet may be based on the time of weeding, availability of labour as well as its economic viability.
