: 30 days after onset of monsoon (20 th July) and three varieties in sub plot viz., V 1 -TAU-1, V 2 -BDU-1, V 3 -TPU-4. Gross and net plot size viz., 4.5 m x 4.4 m and 3.9 m x 4.0 m, respectively. The soil was medium black, clayey in texture, alkaline in reaction and higher in total soluble salt concentration, low in nitrogen and rich in phosphorus, potassium and lime, alkaline in reaction with high base saturation. Sowing was done by dibbling method. From the result of experiment it can be concluded that, among different sowing dates in black gram, the sowing at 20 days after onset of monsoon (10 th July) was found optimum for achieving higher seed yield whenever the onset of monsoon delayed. The black gram variety BDU-1 was found highly productive as compared to TAU-1 and TPU-4.

Rice variety 'Parag' was sown with 30 cm row spacing and 60 kg seed rate/ ha. Experiment was laid out in Randomized Block Design with three replications. Ten treatments were tested viz., N-P-K only 80-50-50 kg/ha (recommended dose of fertilizer-RDF) (N 1), NPK (RDF)+ ZnSO 4 @10 kg/ha through soil (N 2), NPK (RDF)+ ZnSO 4 @10 kg/ha + FeSO 4 @10 kg/ha thorough soil (N 3), farm yard manure (FYM) @ 5 t/ha + NPK (RDF) (N 4), FYM @ 5 t/ha + NPK (RDF) + ZnSO 4 @10 kg/ha thorough soil (N 5), FYM @ 5 t/ha + NPK (RDF) + ZnSO 4 @10 kg/ha + FeSO 4 @10 kg/ha thorough soil (N 6), NPK (RDF) + two foliar sprays of ZnSO 4 @ 0.5 per cent at 20 and 45 DAS (N 7), NPK (RDF)

The present investigation entitled “Effect of Herbicide Combinations on Growth and Yield of Kharif Maize (Zea mays L.)” was carried out during kharif 2019 at College Farm, College of Agriculture, Badnapur, Dist.-Jalna. Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Maharashtra (India). Randomized Block design was used for study comprised of ten treatments. Among treatments, weed free treatment attributed more number of leaves, maximum plant height, dry matter production and leaf area per plant followed by treatment of topramezone 33.6 % SC @ 25.2 g a.i.ha-1 + atrazine 50 % WP @ 250 g a.i. ha-1. Poor growth attributes were recorded in weedy check. Significantly maximum values of yield attributes were recorded in treatment of topramezone 33.6 % SC @ 25.2 g a.i.ha-1 + atrazine 50 % WP@ 250(g)a.i.ha-1 followed by treatment of tembotrione 42 % SC @ 105 g a.i. ha-1+ atrazine 50% WP @ 250 g a,i. ha-1. Minimum values of yield attributes were attributed in weedy check. Treatment of topramezone + atrazine @ 25.2 + 250 g a.i ha-1 as PoE (T6) found effective in limiting weed growth and recorded lower weed index, weed dry matter with higher weed control efficiency followed by tembotrione +atrazine @105 + 250 (g) a.i.ha-1as PoE (T7) at all growth stages of crop. The benefit cost ratio was highest (2.94) with application of topramezone + atrazine @25.2 + 250 g a.i ha-1 followed by tembotrione + atrazine @ 105 + 250 g a.i. ha-1 as PoE (2.81) whereas weedy check recorded significantly lower B:C ratio(1.50) over other treatments.
