RÉSUMÉ
The study was conducted to know the nutrient status, yield, straw and harvest index in 4 different cropping systems viz., (i) manual transplanting; (ii) dry direct seeding; (iii) drum seeding and (iv) machine transplanting 120 soil samples were analysed, 30 from each establishment method. The soil fertility status from different establishment methods was studied by analysing the samples for pH, EC, bulk density, organic carbon, available nitrogen, phosphorous, potassium, iron, zinc, total organic carbon and carbon stock. The study revealed that there is a significant difference in bulk density ranged high in machine transplanting (1.48 Mg m-3) and low in dry direct seeding (1.45Mg m-3). pH of soils was neutral to slightly alkaline in nature and iron content of soils ranged from 5.75 to 8.97 mg kg-1.
RÉSUMÉ
A field experiment to compare weed management practices on growth and yield of zero till chickpea (Cicer arietinum L.) during rabi, 2022 at RARS, Jagtial, Telangana. Treatments include Pendimethalin 38.7 % CS @ 700 g a.i. ha-1 , Topramezone 33.6 % SC @ 20.6 g a.i. ha-1 , Quizalofop ethyl 7.5 % + Imazethapyr 15 % EC @ 100 g a.i. ha-1, T4- Propaquizafop 2.5 % + Imazethapyr 3.75 % (w/w) ME @ 125 g a.i. ha-1 , two hand weedings at 15 and 30 DAS , weed free (Season long) and Un-weeded (Check). Weed free treatment and hand weeded plots showed highest growth and yield attributing characters because of season-long weed-free conditions and better microclimate during critical period of crop respectively. Among different herbicides, Topramezone treated plot recorded higher growth parameters viz.; plant height (38.7 cm), dry matter accumulation (320.8 g m-2) and yield attributing characters viz.; total number of pods plant-1 (30.97), with seed yield (1397 kg ha-1), haulm yield (2518 kg ha-1) and harvest index (35.7 %). Post emergence herbicide topramezone can be effectively adopted for getting higher yield of chickpea in rice fallow zero tillage conditions.
