Two sets of experiments were conducted on sandy loam soils at Anand, India during the rabi (winter) seasons of three years (1993\94-1995\96) to study the effects of farmyard manure, nitrogen, phosphorus and potash as well as the method and time of sowing and irrigation on the growth and yield of chicory. Application of farmyard manure and phosphorus had no beneficial effect, whereas the application of nitrogen at 100 kg\ha and potassium at 50 kg\ha increased yield by 12n09 and 3n33 %, respectively, on a pooled basis. Crops sown either in rows 30 cm apart or broadcast performed equally well with respect to dry root yield. Sowing of chicory on 5 November gave the highest dry root yield. Delayed sowing significantly reduced the dry root yield. Scheduling irrigation at an irrigation water : cumulative pan evaporation ratio of 0n7 produced maximum dry root yield.

A field experiment was conducted at Instructional Farm, Navsari Agricultural University, Navsari during 2013-14 and 2014-15 with a view to study the crop-weed competition as influenced by different weed management practices in Rabi (winter season) sorghum (Sorghum bicolor L.). Twelve weed management treatments were evaluated in a randomized block design with four replications. Preemergence (PE) application of atrazine 0.5 kg/ha + pendimethalin 0.25 kg/ha as tank mixture significantly reduced weed population and weed biomass, increased the weed control efficiency at early stage, next to weed free treatment. However, at the rest of the growth stages, two HW and inter culturing (IC) at 20 and 40 DAS, atrazine 0.5 kg/ha PE + HW and IC at 20 DAS, pendimethalin 0.5 kg/ha PE + HW and IC at 20 DAS effectively controlled the weeds, reduced the weed biomass and increased the weed control efficiency. Nutrient losses by weeds were highest under unweeded control and lowest with weed free condition followed by application of atrazine 0.5 kg/ha PE + HW and IC at 20 DAS.
