A study was conducted in an ongoing experiment under AICRP on micronutrients at nursery jhilli of RPCAU, research farm. The experiment consisted of thirteen treatments, of which twelve combinations were of four doses of zinc (Zn) (2.5, 5.0, 7.5 and 10 kg ha-1), three frequencies (only once, alternate year and every year) of application along with control with the no-zinc application. Rice and wheat crops were grown in succession with the recommended dosages of fertiliser viz. 120:60:40 of N: P2O5: K2O applied as Urea, DAP, and Potash, respectively. Surface soil samples (0-15 cm) were collected after the harvest of the wheat crop in the year 2018, i.e. after completion of six years of the experiment, and analysed for soil physical and chemical properties. The availability of nitrogen, sulphur, organic carbon content and aggregate stability increased, and the bulk density, phosphorous availability decreased with increasing doses and zinc application rates. No effect on soil availability of potassium, pH and EC. The treatment T7 i.e., application of zinc @ 7.5 kg Zn ha-1 in alternate year application was the best treatment with regards to yield of rice-wheat cropping (982.9 q ha-1) and also for good physical and chemical properties of the soil.

Abstrak :Gulma kirinyuh sangat berpotensi untuk dijadikan pupuk organik karena kandungan unsur  hara dalam jaringannya yang tinggi. Biomassa kirinyuh memiliki kandungan hara N 2,65%, P 0,53% dan K 1,9% sehingga dapat dimanfaatkan sebagai sumber hara yang potensial dalam upaya peningkatan produksi kedelai dan perbaikan kesuburan tanah. Penelitian ini bertujuan untuk mengetahui tanah yang sesuai dalam menunjang produksi tanaman kedelai akibat dari penambahan bahan organik kirinyuh. Penelitian ini bertujuan untuk mengetahui tanah yang sesuai dalam menunjang produksi tanaman kedelai akibat dari penambahan bahan organik kirinyuh. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) Faktorial yang terdiri atas 2 (dua) faktor dengan pola 4 x 3 sehingga diperoleh 12 kombinasi perlakuan. Faktor pertama adalah dosis mulsa organik kirinyuh (D), terdiri atas 4 (empat) taraf yaitu: D0 = 0 ton ha-1, D1 = 6 ton ha-1, D2 = 12 ton ha-1, D3 = 18 ton ha-1. Faktor kedua adalah waktu aplikasi mulsa organik kirinyuh (W) terdiri atas 3 (tiga) taraf yaitu saat tanam (W1), 1 minggu setelah tanam (W2), 2 minggu setelah tanam (W3). Peubah fisika dan kimia tanah yang diamati meliputi bulk density, stabilitas agregat tanah, kapasitas tukar kation dan kejenuhan basa.Hasil penelitian menunjukkan bahwa dosis mulsa organik kirinyuh berpengaruh sangat nyata  terhadap sifat fisika tanah yaitu bulk density. Dosis mulsa organik kirinyuh 6 - 18 ton ha-1 menurunkan nilai bulk density namun tidak meningkatkan stabilitas agregat tanah. Waktu aplikasi mulsa organik kirinyuh yang awal tidak menunjukkan pengaruhnya terhadap sifat fisika dan kimia tanah yang diamati. Tidak terdapat interaksi antara dosis dan waktu aplikasi mulsa organik kirinyuh terhadap semua peubah yang diamati.   Granting Kirinyuh (Cromolaena odorata L.) As Organic Mulch In Soybean Plants (Glycine max L.) As Well As Its Effects On The Physical And Chemical Properties Of SoilAbstract. Weed kirinyuh potential to be used as organic fertilizer because the content of nutrient elements in its high. Biomass kirinyuh contain nutrient N 2.65%, 0.53% P and K 1.9% so that it can be utilized as a source of potential nutrient in an attempt to increase the production of soybean and improvement of soil fertility. This research aims to know the appropriate ground support the soybean crop production resulting from the addition of organic matter kirinyuh. This research aims to know the appropriate ground support the soybean crop production resulting from the addition of organic matter kirinyuh. This research was performed using Random Design Group (RAK) Factorial of 2 (two) factors with the 4 x 3 pattern so obtained 12 combination treatment. The first factor is a dose of organic mulch kirinyuh (D), consisting of four (4) levels, namely: a D0 = 0 ton ha-1, D1 = 6 ton ha-1, D2 = 12 ton ha-1, D3 = 18 ton ha-1. The second factor is the time of organic mulch application kirinyuh (W) consists of 3 (three) level that is when planting (W1), 2 weeks after planting (W2), 2 weeks after planting (W3). Soil physical and chemical variables were observed include bulk density, soil aggregate stability, cation exchange capacity and saturation of the base. The results showed that a dose of organic mulch kirinyuh very real effect against soil physical properties namely bulk density. A dose of organic mulch kirinyuh 6-18 ton ha-1 lowers the values of bulk density but does not increase the stability of soil aggregates. Organic mulch application time kirinyuh the beginning does not show its effects on the physical and chemical properties of the soil is observed. There is no interaction between the dose and time of application of organic mulch kirinyuh against all variables were observed.

Field experiment was conducted for two consecutive years at the research farm of Baba Raghav Das Post Graduate College, Deoria, Uttar Pradesh, India to evaluate the effect of different tillage practices on soil health andcrop productivity of wheat under the rice-wheat cropping system of Indo-Gangetic Plains of India under the irrigated ecosystem.Results revealed thattreatment T3 produced significantly higheryield attributes in terms of number of ear bearing shoots (407)as compared to T4(390). However, it was also recorded that the grain weight per spike and test weight were significantly lower in T3 and T4over rest of the practices. The similar trends were followed in case of grain yield under the T3 (45.60) being on a par with T4 (45.50 but it was recorded significantly superior over rest of the tillage practices. With respect to the soil physical and chemical properties, it was also noticed significantly higher under the treatment T4 as compared to other treatment.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.
