 ABSTRACT

A field experiment was conducted during summer 2014 at the College Farm, Navsari Agricultural University, Navsari to study the effect of row spacing and weed management practices on growth and yield of maize (Zea maize L.). Experiment result revealed that the growth and yield parameters viz., plant height, number of leaves per plant, dry matter production per plant, number of cobs per plant, cob weight and grain weight per cob were influenced significantly due to row spacing. Significantly higher values of these parameters were recorded under 60 cm (S2) row spacing. However, grain and stalk yield were significantly higher under 45 cm (S1) row spacing. From economic point of view, the maximum net realization of Rs. 44911/ha and B:C ratio 1:3.66 were accrued under spacing 45 cm (S1) as compared to 60 cm (S2) spacing. Weed management treatments influenced significantly various growth and yield attributing characters viz., plant height, number of leaves per plant, dry matter production per plant, number of cob per plant, cob weight, grain weight per cob and 100 grain weight which caused significant effect on grain and stalk yield of maize. In most of the cases, treatment weed free (W2) was found superior than rest of the treatments, but remained at par with atrazine 1.0 kg/ha as pre-emergence + HW and IC at 30 DAS (W3) and atrazine 0.5 kg + pendimethalin 0.25 kg/ha tank-mix pre-emergence fb 2,4-D (SS) 0.5 kg/ha at 20 DAS (W6). The highest net realization of Rs. 48631/ha was obtained from weed free (W2) treatment followed by treatments W3 (Rs. 48342/ha) and W6 (Rs. 46559/ha). The highest B: C ratio (1:3.79) was observed in treatment W3 followed by treatment W6 (1:3.72) and W4 (1:3.52).

Key words: Row spacing, Weed management, Tank-mix herbicide, Atrazine, Pendimethalin and 2, 4-D.
