A field experiment was conducted for two consecutive years (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 season with four treatments. The treatments consisted of M1 (RDF (Recommended dose of fertilizers) - Control), M2 (10t FYM (Farm Yard Manure) 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 available NPK after harvest of maize crop were significantly increased 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.

The treatments consisted of M1 (RDF- Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). The nutrient content in rice at various growth periods was significantly increased with the application of 100% NPK in combination with FYM @ 10t ha-1. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.

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.

An experiment was conducted for two consecutive years (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 wet season with four treatments and five replications. The treatments consisted of M1 (recommended dose of fertilizers (RDF) - Control), M2 (10t farmyard yard manure (FYM) ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). Data collected on biometric observations (plant height, number of tillers, dry matter accumulation) and yield. The yield of crop was significantly increased with the application of 100%NPK in combination with FYM @10t ha-1. However, it was at par with green manuring along with the application of 100% RDF (NPK).Thus, green manure in situ with Dhaincha may be used as an alternative organic source of nutrients to the FYM.

The method used in this research was two-factor Randomized Block Design with split plot arrangement and three replications. The main plot was the mulch type which consists of three treatments, namely: control, cogon grass and silver-black plastic mulch, and as sub plot was the dose of gandasil-B which consists of four 4 levels, namely: 0, 1, 2, and 3 g L-1 water. Results showed that the interaction between different types of mulch and gandasil-B fertilizer only had significant effect on the diameter of the stem, the number of productive branch, the number of fruit per plant, and the weight of fruit per plant. The utilization of silver-black plastic mulch and gandasil- B fertilizer at the concentration of 3 g L-1 water showed more number of productive branch (14.00 branches) and number of fruit (151.17 fruits) per plant and the weight of fruit (166.52 g) per plant was significantly higher.Keywords : Mulch, cogon grass, silver-black plastic, Gandasil-B, inland peat soil                                                                                                                                       ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh jenis mulsa dan pupuk gandasil-B terhadap pertumbuhan dan hasil tanaman cabai rawit (Capsicum fruestescens L.) pada tanah gambut pedalaman. Percobaan ini menggunaakan Rancangan Acak Kelompok (RAK) disusun secara split plot dengan dua faktor perlakuan dan tiga ulangan. Sebagai petak utama, yaitu jenis mulsa terdiri dari tiga jenis, yaitu : kontrol, mulsa alang-alang dan mulsa plastik hitam perak. Sebagai anak petak adalah dosis pupuk Gandasil-B terdiri dari 4 taraf perlakuan, yaitu : 0, 1, 2 dan 3 g L-1 air. Hasil penelitian menunjukkan bahwa interaksi penggunaan jenis mulsa dengan pupuk gandasil-B hanya berpengaruh nyata terhadap diameter batang, jumlah cabang produktif, jumlah buah per tanaman dan berat buah per tanaman. Penggunaan mulsa plastik hitam perak dan pupuk gandasil-B 3 g L-1 air diperoleh jumlah cabang produktif (14.00 cabang) dan jumlah buah (151.17 buah) per tanaman) nyata lebih banyak dan berat buah (166.52 g) per tanaman nyata lebih tinggi.Kata kunci : Mulsa, alang-alang, plastik hitam perak, pupuk gandasil-B, gambut pedalaman
