(2011-2012 and 2012-2013) on fine texture soils of Agricultural college farm, Bapatla. The experiment was laid out in a randomized block design in kharif seasonwith four treatments. The treatments consisted of M1 (RDF - Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). During the immediate rabi, the experiment was laid out in a split-plot design without disturbing the soil for succeeding maize with the four treatments given to kharif rice as main plot treatments and each of these divided into five sub-plots to receive five levels of fertilizer NPK application viz., N1 - 75%NPK, N2 - 100% NPK, N3 - 125% NPK, N4 - 150% NPK and N5 - 175% NPK for succeeding maize. Data collected on soil physico-chemical properties after harvest of maize crop were relatively improved with the application of 100%NPK in combination with FYM @10t ha-1 to preceding rice crop, irrespective of the NPK levels applied to succeeding maize crop. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.

Aim: To find out the direct and residual effect of application of organics, inorganics and their combination on yield and yield parameters of rice-maize cropping system. Study Design: The experiment was laid out in randomized block design during kharif season and split plot design during rabi. Place and duration of Study: At Agricultural college farm, Bapatla during 2018-19 and 2019-20. Methodology: After the preliminary layout, paddy was sown in kharif and maize was sown in rabi season. Vermicompost and green leaf manure were applied two weeks before sowing of paddy. Treatments applied for paddy were considered as main plots and each main plot was divided into two sub plots during rabi. Results: Higher grain yield, straw yield, drymatter production at tillering stage were recorded with the application of 50% RDN through vermicompost +50% RDN through inorganics (T9) during both the years of study. However, in succeeding maize, the kernel yield, straw yield and yield attributing characters (drymatter, cob length and test weight) were significantly highest in the treatment which received 75% RDN through green leaf manure+ 25% RDN through inorganic (T5). Among the fertilizer levels applied to maize, S2 (100% RDF) recorded significantly higher dry matter production over S1 (50% RDF) at all the stages of crop growth and during two years of experimentation. Conclusion: Substitution of 50 % N through vermicompost improved rice yield and yield attributes whereas substitution of 75% N through GLM have shown better residual effect in terms of improvement of yield and yield attributing characters of maize. Among the subplots application of 100% RDF significantly increased the yield when compared to 50% RDF.

Weed Infestation

Background: Maize followed by summer pulses is the emerging cropping system in many places in India. Herbicides are the efficient tools for checking weed infestation and their usage is increasing throughout the globe due to increased labour cost and quick weed control. Some herbicides do not degrade quickly and may remain in the soil for weeks, months or years after application and may inhibit the growth of succeeding crops. Methods: Field experiment was conducted in a randomized block design (RBD) during rabi and summer seasons of 2017-18 and 2018-19 to know the residual effect of different herbicides applied in maize on succeeding greengram. Result: The present study revealed that lower density and dry weight of total weeds and higher yield attributes and yield was recorded with the practice of adopting two hand weedings at 15 and 30 DAS, which was however, at par with atrazine 1.0 kg ha-1 as PE fb one HW at 30 DAS, atrazine 1.0 kg ha-1 as PE fb topramezone 30 g ha-1 as PoE and atrazine 1.0 kg ha-1 as PE fb tembotrione 120 g ha-1 as PoE, without any significant disparity among them. Herbicides applied in maize did not alter statistically the enzyme activity and microbial count in the soil at harvest of succeeding greeengram.

The aim of this study was to investigate the effect of zinc enriched Farm Yard Manures (FYM) on zinc deficient loamy sand soil and yield of mungbean[Vigna radiata (L.) Wilczek.]. Treatments consisted of 15 combinations of three levels of FYM i.e. F0 (no FYM), F1 (FYM @ 5 t ha-1) and F2 (FYM @ 10 t ha-1) and five treatments of enrichment i.e. Zn enrichment (EnZn1, EnZn2, and EnZn3) at three levels of Zn (2.5, 5.0 and 7.5 kg Zn ha-1) @ 500 kg ha-1 FYM and without enrichment (Zn0 and Zn1) at two levels of Zn (inorganic salts) i.e. 0 kg and 5 kg Zn ha-1, replicated thrice in factorial randomized block design (FRBD)during 2012. The enrichment process was started 50 days before their use in kharif season experiment on mung bean.The average improvement in seed yield of mungbean was 1179 kg ha-1. Zinc-enriched FYM and their straight application produced (10983kgha-1) 31.86 and 22.83% higher grain yield, respectively, relative to control Zn0 (8959kg ha-1).The yield was increased due to enrichment and it was achieved by 9.04 % over straight application of zinc. Zn uptake was recorded significantly higher under the EnZn2 (143.96 g ha-1) which was at par with EnZn3 (148.23 g ha-1) followed by EnZn1 (118.50 g ha-1) all these values are significantly higher than Zn0 (92.02 g ha-1).The average improvement in total uptake of Zn by mungbean was 48.71%higher due to zinc enriched FYM than the straight application of zinc. The application of zinc enriched FYM significantly increased available N, organic carbon andDTPA-extractable Zn with increasing the level of enrichment.The application of zinc enriched FYM had non-significant effect on bulk density, saturated hydraulic conductivity and moisture retention at 1/3 and 15 bar and CEC than control.Application of 2.5 kg Zn ha-1which wascomparable to enriched with FYM,in terms of higher seed yield of mungbean.

Rice Husk Biochar

Rice husk biochar and compost application are expected to improve soil chemical properties such as pH, organic carbon, and available P in Ultisol, which in turn improves crop growth and P uptake by plants. The purpose of this research was to analyze the effect of the combination of rice husk biochar and compost on the soil chemical properties (pH, organic carbon, and available P), maize growth, and P uptake by maize in an Ultisol. The research used a Randomized Block Design with six treatments (P0: control; P1: 4 t biochar ha-1; P2: 30 t compost ha-1; P3: 4 t biochar ha-1 and 30 t compost ha-1; P4: 8 t biochar ha-1 and 30 t compost ha-1; P5: 4 t biochar ha-1 and 60 t compost ha-1) and four replications. The result showed that the combination of 8 t rice husk biochar ha-1 and 30 t compost ha-1 showed a significant effect on increasing pH, organic carbon, and available P in an Ultisol, increasing the height of maize crops at 4 and 6 WAP (weeks after planting). However, it had no effect on the number of leaves and showed an effect on the increase in P uptake of maize crop.
