The experiment was laid out with twelve cropping systems as treatments in Randomized Block Design (RBD) with three replications. The twelve combinations of cropping systems tested during kharif and rabi seasons were rice – rice (check), maize + soybean (2:4) – tomato, maize + soybean (2:4) - rice, maize - sunflower + chickpea (2:4), maize - chickpea, Bt cotton + soybean (1:2) on broadbed – sesame + groundnut (2:4), Bt cotton - sesame + blackgram (2:4), soybean – wheat, soybean – sunflower + chickpea (2:4), turmeric – sesame, turmeric + soybean (1:2) on flat bed – bajra and turmeric + soybean (1:2) on broadbed – sesame + blackgram (2:4). On system basis, significantly higher productivity in terms of rice equivalent yield (REY) of 23830 kg ha-1 was recorded with turmeric+soybean (1:2) BBF– sesame+blackgram (2:4) turmeric – sesame cropping sequence. However it was on par with turmeric – sesame and turmeric + soybean (1:2) on flat bed – bajra crop sequence with productivity of 23332 kg ha-1 and 21389 kg ha-1 respectively. Lower productivity was recorded with rice-rice cropping system (10725 kg ha-1). Significantly higher system net returns were recorded with Bt. cotton – sesame + black gram (2:4) on BBF (Rs222838 ha-1) closely followed by Bt Cotton + Soybean (1:2) (BBF) - Sesamum + Groundnut (2:4) (Rs221160 ha-1) and Maize+soybean (2:4)–tomato (Rs212909 ha-1). Lower system net returns were recorded in conventional rice-rice system (Rs88179 ha-1). Bt. cotton – sesame + black gram (2:4) and Bt Cotton + Soybean (1:2) (BBF)- Sesamum + Groundnut ((2:4) and Maize+soybean (2:4)–tomato were economically superior with REE of 152.71%, 150.81% and 141.45%. Rice- Rice cropping adopted by majority of farmers is less productive and economically inferior indicating wider scope of diversifying existing rice- rice cropping system with high productive, economically viable cropping systems in vertisols of Northern Telangana Zone.

Aim: To determine the effect of integrated use of inorganic phosphorus along with phosphorus solubilising bacteria and farmyard manure on nutrient Content and uptake in Bt-Cotton. Study Design: The experiment was laid out in randomized block design with three replications. Place of Study: At College Farm, Agricultural College, Bapatla, Guntur district. Methodology: After the preliminary layout, the Tulasi-BG II hybrid of cotton was used as a test crop, with a spacing of 90 cm x 60 cm in the experimental site. Plant samples were collected at 45, 90 DAS, and harvest. Plant samples were shade dried and kept in hot air oven at 75°C until a constant weight was obtained. Samples were powdered and then analysed using standard chemical procedures. Results: The uptake of macronutrients viz., N, P, and K was markedly influenced by the treatments with maximum values recorded by the treatment that received 60 kg P2O5 ha-1 + FYM + PSB. Their uptake significantly differed with increase in dose of phosphorus applied at all growth stages. Combined use of 60 kg P2O5 ha-1 + FYM + PSB resulted in a significant increase in uptake of all micronutrients (Zn, Cu, Mn, and Fe) at all stages except Cu at 90 DAS. Conclusion: Application of phosphorus combined with FYM and PSB not only reduce inorganic phosphorus fertilization but also enhance the uptake of nutrients and plant nutrient content by providing favourable conditions for plant growth. Application of 30 kg P2O5 ha-1+ PSB + FYM was found to be on a par with addition of only 60 kg ha-1P2O5. Hence the P dose can be reduced to half by integrating with PSB and FYM.

Weed Control Efficiency

Background: Time of pre-emergence herbicide application is an important factor that decides the efficiency of herbicide. If the pre-emergence herbicide is not applied at appropriate time, it may cause ineffective weed control or toxicity to crops. With this background, a field experiment was conducted at TNAU, Madurai to optimize the time of pre-emergence herbicides namely pendimethalin and oxyfluorfen application for effective weed management in irrigated blackgram. Methods: The experiment was laid out in randomized block design with three replication. Treatments were application of pendimethalin at 0.75 kg ha-1 and oxyfluorfen at 0.2 kg ha-1 on 1, 2, 3, 4 days after sowing, weed free check and unweeded check. Result: Results of the study revealed that oxyfluorfen gave maximum weed control efficiency as compared to pendimethalin, but toxicity to the crop was observed when oxyfluorfen was sprayed after 2 days of sowing. Yield and economics were achieved higher with application of 0.75 kg ha-1 of pendimethalin at 2 DAS, which was on par with application of 0.2 kg ha-1 of oxyfluorfen at 1 DAS due to lesser toxicity. Application of 0.75 kg ha-1 of pendimethalin and 0.2 kg ha-1 of oxyfluorfen didn’t leave any herbicide residue after harvest. Hence, application of 0.75 kg ha-1 of pendimethalin at 2 DAS and 0.2 kg ha-1 of oxyfluorfen at 1 DAS can be recommended for effective weed management in irrigated balckgram.
