    EFFECT OF INTEGRATED NUTRIENT MANAGEMENT AND MULCHING ON YIELD AND QUALITY OF MUSTARD (BRASSICA JUNCEA L.) AND SOIL QUALITY IN PARTIALLY RECLAIMED SODIC SOIL
    (ANDUAT,Kumarganj,ayodhya, 2021-12-02) Diwakar, Sandeep Kumar; Kumar, Neeraj
    An experiment on “Effect of integrated nutrient management and mulching on yield and quality of Mustard (Brassica juncea L.) and soil quality in partially reclaimed Sodic Soil.’’ was carried out during Rabi session 2018-19 and 2019-20 at Agronomy Research Farm, of A.N.D.U.A&T. Kumarganj, Ayodhya (U.P.). The experiment was consists of fourteen treatments i.e. T1- Control (NO NPK + NO Mulching), T2- 100% NPK + NO Mulching, T3- 75% NPK + N-25% (FYM) + NO Mulching, T4- 100% NPK+ Sulphur @40 kg + NO Mulching, T5 -100% NPK+ ZnSO4 @25 kg + NO Mulching, T6 - 75% NPK+ N-25% (FYM) + Sulphur @40 kg + NO Mulching, T7 -75% NPK+ N-25% (FYM) + ZnSO4 @25kg + NO Mulching, T8- Control + mulching @ 5 t/ha-1, T9-100% NPK + Mulching @ 5t/ha-1, T10 - 75% NPK + N-25% (FYM) Mulching @ 5 t/ha-1, T11 - 100% NPK+ S @ 40 kg + Mulching @5 t/ha-1, T12 -100% NPK+ ZnSO4 @ 25 kg + Mulching @ 5 t/ha-1, T13-75% NPK+ N-25% (FYM) +S @ 40 kg + Mulching @5 t/ha-1 and T14 -75% NPK+ N-25% (FYM) + ZnSO4 @25kg + Mulching @5 t/ha-1 treatments were laid out in Randomized Block Design (RBD) with three replications. The initial properties of soil was silty loam in texture, well drained, having pH (8.20), EC (0.25 dS/m), organic carbon (0.33%) available N (137 kg ha-1), available P (15.35 kg ha-1), available K (249.25 kg ha-1), available sulphur (15.35 ppm) at commencement of the experiment. The variety Varuna was sown proper moisture stage on 20th October, 2018-19 and 27th October, 2019-20. The nitrogen, phosphorus and potassium were applied throw Urea, SSP and Muriatic of potash @ 80, 40 and 20 kg ha-1, respectively. As per experiment the results revealed that the growth attributes, yield attributes and yields, nutrient content and uptake, soil properties and economics were affected by different INM and mulching practices. The maximum values of growth attributes was recorded with the treatment T13 at all growth stages. The maximum yield attributes and yield viz., number of siliquae plant-1, length of siliquae, number of seeds siliqua-1, test weight, seed yield (21.05 and 22.08 q ha-1), stover yield (49.42 and 51.43 q ha-1) and harvest index (29.90 and 30.87 %) were recorded under the treatment T13-75% NPK+ N-25% (FYM) +S @40 kg + Mulching @5 t/ha-1.in both the years. Similarly, the maximum uptake by mustard crop was also recorded under the under the treatment T13 during both years. Economic evaluation of the treatments revealed that maximum cost of cultivation (Rs. 39101.00 and 40526.00 ha-1), gross return (Rs. 88509.00 and 92835.00 ha-1), net return (Rs. 49408.00 and 52309.00 ha-1) was calculated with the treatment T13- 75% NPK+ N-25% (FYM) +S @40 kg + Mulching @5 t/ha-1 while, maximum B:C ratio (1.32 and 1.45) was found with the treatment T6 - 75% NPK+N-25% (FYM)+ 40 kg S + NO Mulching. The maximum buildup of organic carbon content (%), maximum availability of soil nutrients (NPK kg ha-1 and S ppm) and microbial population were found under the treatment T13.

    Depth wise studies of soil properties as affected by different agroforestry system
    (ANDUAT,Kumarganj, Ayodhya, 2021-08-17) Kumar, Deepak; Kumar, Suresh
    Soil Sampling was done on GPS basic Investigation area of the agro Forestry farm to evaluate the effect of plantations of tree species and cropping systems on soil Physico-chemical and biological characteristics and their correlations and carbon sequestration.
