Abstract
A field experiment was conducted in 2002 and 2003 at Pandit Jawaharlal Nehru College of Agriculture and Research Ir stitute, Karaikal with the objective of identifying the best method of sowing and testing the relative efficacy of different h1 rbicides in comparison with the conventional weed management in sesame under irrigated condition. The results n vealed that the seed yield was significantly influenced bY methods of sowing and weed management in both the years. H1gher seed yield of 654 and 63 9 kg ha was obtained in line sowing method with a spacing of 30 x 30 cm during 2002 a id 2003, respectively. Among the herbicides, pre-plant incorporation of fluchloralin 1.0 kg ha· along with one hand v eeding (HW) on 30 DAS recorded significantly the highest seed yield of 758 and 745 kg ha· during 2002 and 2003, r1 spectively followed by preemergence application of alachlor 1.25 kg ha along with one HW at 30 DAS. J( ey words : Sesame, sowing method, chemical weed control. After the single crop rice, the farmers in the coast I deltaic region of Karaikal are raising summer rainfed sesame. They are incurring yield loss in sesame due o poor plant stand in broadcasted method of sowing, which they are adopting till now. Though, the conventional methods of weed control viz., hand pulling/hand hoeing is very much effective, the high wage and non-availability of labour at critical stages often lead to late weeding and cause economic loss in term of sesame yield in this region. In the present study, different methods of sowing and herbicidal control with hand weeding was tried to find solutions for the above said p roblems. MA ERIALS AND METHODS The treatment combinations of the study cons1 ted of two factors viz., methods of sowing (M1: Broadcasting; M2: Line sowing -30 cm x 30 cm) and weed management methods (W1: Hand weeding (HW) twice at 15 and 30 DAS; W2:Pendimethalin 0.75 kg ha 1 (PE) tHW at 30 DAS; W3: Fluchloralin 1.00 kg ha. (PPI) + HW at 30 DAS; W4: Alachlor 1.25 kg ha (PE) + HW at 30 DAS; Ws: Weed free; W6: Unweeded ched All the treatments in this experiment was repli ated thrice in factorial randomized block design (FRBD). The soil type of the experimental field was sand clay loam with low status of available nutrients viz., iitrogen (134.4 and 142.8 kg ha-1), P20 5 (6.5 and 5.9 kg ha) and K20 (84.4 and 90.6 kg ha) during 2002 and 2003, respectively. A common dose of 35:23:23 kg ha· of N, P20s and KzO was applied to all the treatments. Sesame seeds (5 kg ha) were sown as per the treatment in lines and broadcasting. A spacing of BO cm between rows and 30 cm within rows was followed for line sowing. After sowing, the seeds were covered with soil. In broadcasting method, the required seeds were mixed with four times of its volume with dry sand and broadcasted uniformly in the treatment plots and covered with soil gently. The pre-emergence (PE) herbicides viz., pendimethalin and alachlor were sprayed uniformly over the soil using high volume sprayer. 'Ole herbicides were sprayed on 3 DAS as per the treatment schedule. Fluchloralin was applied as a pre-plant incorporation in the soil before sowing of the seeds and irrigated immediately. RESULTS AND DISCUSSION · Weed density Methods of sowing significantly influenced the total weed density at 45 DAS. Maximum weed density m·2 was noticed in broadcasting (M1) followed by line sowing (M2) during 2002 and was found to be nonsignificant during 2003. The highest weed density in broadcasting method might be due to wider spacing among the plants, which induced the conducive microclimate for rapid development of weeds. This is in
