Field experiment was conducted at Agricultural Research Station, Borwat Farm, Banswara during Kharif-2010 to find out the optimum plant geometry and fertility levels for inter specific cotton hybrids with three cotton hybrids (JKCHB-214, RAHB-170 and DCH-32), two plant geometries (90 × 60 and 90 × 45 cm) and three fertility levels (75,100 and 125 % RDF). Sowing of JKCHB-214 cotton hybrid gave significantly higher seed cotton yield (1558 kg ha-1) over DCH-32 cotton hybrid. The maximum seed cotton yield (1754 kg ha-1) was observed under wider plant geometry of 90 × 60 cm than closer plant geometry of 90 × 45 cm. Though, yield attributing parameters such as bolls plant-1 and boll weight were statically improved in wider as compared to closer spacing it could be increase the seed cotton yield. Among fertility levels, similar seed cotton yield was recorded with the application of 100 per cent RDF (1555 kg ha-1) and 125 per cent RDF (1602 kg ha-1) but both were significantly better than that of 75 per cent RDF and plant geometry 90 x 60 cm seemed to be ideal for inter specific hybrid cotton for realizing higher productivity under the specific agro climatic zone IV b of Rajasthan.Keywords

An experiment was conducted during two consecutive years of Zaid 2008 and 2009 at Agricultural Research Station, Borwat Farm, Banswara to find out optimum sowing date and suitable herbicide for weed management in Zaid urdbean under Humid Southern Plain Zone of Rajasthan. Results revealed that the maximum seed yield (961 kg/ha), net return (Rs. 23848/- ha-1) and B:C (1.45) was observed under sowing of urdbean on 15th March over sowing of urdbean on 5th and 15th April, respectively. However, it was found at par with sowing of urdbean on 25th March seed yield (924 kg/ha), net return (Rs. 22769/- ha-1) and B:C (1.42). In weed management, application of Fluchloralin @ 0.75 kg a.i./ha PPI gave significantly higher seed yield (918 kg/ha) net return (Rs. 21888/- ha-1) and B:C (1.33) over weedy check (control), but it was found at par with application of Pendimethalin @ 0.75 kg a.i./ha PE and weed free in the pooled analysis. Sowing of urdbean under different dates, the weed population m-2, weed dry matter accumulation (g m-2) and weed control efficiency at 30 DAS were found not significant with each other during both the years as well as in the pooled analysis. Application of Fluchloralin @ 0.75 kg a.i./ha PPI gave significantly higher weed control efficiency (51.80 %), lowest weed population (13.40 m-2) and weed dry matter accumulation (15.57 g m-2) at 30 DAS over weedy check (control), but it was found at par with the application of Pendimethalin @ 0.75 kg a.i./ha PE and weed free in the pooled analysis.Keywords
