COMPARITIVE ECONOMICS OF IN VITRO GROWN PLANTLETS OF CLONAL APPLE MM 106 AND MM 111 ROOTSTOCKS
There is a paucity of information available on the practicality, suitability, and profitability of in vitro raised plants of clonal apple rootstocks as compared to field-multiplied plants through traditional methods. The present investigation was carried out at the Plant Tissue Culture laboratory of the School of Biotechnology (SBT) and the Tissue Culture laboratory of the Advanced Centre for Horticulture Research (ACHR), Udheywalla, SKUAST-Jammu, Main Campus, Chatha. Results indicated that the unit cost for in vitro raised plantlets from explants excised from a 2-3 year-old mother block of clonal apple rootstock MM 106 was estimated to be Rs. 44.56, which included Rs. 41.38 and Rs. 3.18 at the tissue culture production phase and greenhouse production phase, respectively, whereas, in MM 111 clonal rootstock, the unit cost for in vitro raised plantlets was estimated to be Rs. 36.95, which included Rs. 34.29 and Rs. Moreover, as per the general practices in the literature, the estimated production cost of an ex vitro seedling is Rs. 150.
Mechanism and Potential Role of Mycorrhizal Fungi as Biocontrol Agents
AM fungi establish a symbiotic relationship with most of the plant root systems, thereby forming a vital part of terrestrial ecosystems. It is unique association that play important role in nutrient exchange, increase the uptake of mineral nutrients from the soil through the external hyphal network (extra-radical hyphae) by solubilizing phosphate, nitrogen and other essential micro nutrients such as Ca, Cu, Mn and Zn. AM (fungi) association also improved soil structure, increase drought tolerance and enhanced beneficial harmone such phytoalexins, cellulose deposition, hydroxyproline-rich glycoproteins, phenolics, peroxidases, chitinases, β-1-3 glucanases and pathogenesis related proteins that leads to resistance against plant pathogens. These fungi have the antagonistic ability against plant pathogens and act as bio-stimulants and bio-protectors that ensure crop production and protection, reducing plant pathogenic population to safeguard sustainable farming without harming the environment. As biocontrol agents, mycorrhiza reduces the incidence and severity of several plant diseases caused by soil borne pathogens and nematode.
Investigation of three lateritic soils mixed with Geopolymer based Kaolin – Rice husk ash as road construction materials.
This paper explores the usage of two wastes (Portland cement powder (PCP) and rice husk ash (RHA) for improving the engineering strength of threesubgradelateritic soil gotten from where road failures are prominent in Nigeria. It displays an experimental perception on the stabilization of the soil with RHA+PCP-based geopolymer. In the RHA-PCP based geopolymer, the stabilizers were blended with the lateritic soil in varying quantities ranging from 2 to 10% for RHA-PCP stabilization. Subsequently, the optimum percentage of RHA-PCP was activated with sodium silicate. The results demonstrate improved mechanical with the two stabilizers. Conversely, the stabilization done with RHA at 10% and geopolymer (6% cement plus 6% RHA and 8% PCP) were the optimal. By and large, RHA stabilization behaved better than PCP geopolymer stabilization.
MAPPING THE USE OF SUBSIDIED FERTILIZER ON RICE FARMING ACTIVITIES
For a long time, farmers believe that the use of fertilizers will greatly affect the increase in productivity of their rice farming. So that fertilizer is seen as the main production factor in increasing rice production. In fact, the share of fertilizer expenditure to farm costs are only around 9-13%, the largest share of costs is precisely in labor costs of around 60% of total farming costs. However, the main problem is the low ability of the majority of farmers to buy fertilizer in cash, so they have to pay above HET (Highest Retail Price), through a payment mechanism after harvest (yarnen). Based on this information, the purpose of this study is to analyze the mapping of the use of subsidized fertilizers in rice farming activities. Based on the results of the study that the factors that affect farm productivity (production per harvested area) partially (individually) are various independent factors included in the regression model, namely: use of seeds, use of urea fertilizer, use of TSP/SP-36 fertilizer, use of pesticides and the use of hired labor was only the variable of the use of urea fertilizer and TSP/SP-36 fertilizer which had a significant effect on the resulting productivity. For this reason, recommendations that can be given from the results of this study, namely socialization for farmers in giving fertilizer doses so that they are in accordance with recommendations from the local government/service are important to continue to pay attention to in supporting the increase in national rice production.
Evaluation of wheat varieties and their validation through CERES-Wheat model under lower foothills of Shivalik range of N-W Himalayas
Field experiments were conducted at Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, J&K UT, India during rabi (winter) season of 2015-16 and 2016-17 with 3 wheat varieties (HD 2967, RSP 561 and WH 1105), 3 sowing environments/dates (25th October-early, 14th November-normal and 4th December-late) and 3 N-levels (100, 125 and 150 kg ha-1) replicated thrice in split split plot design under sub-tropical irrigated conditions of lower foot hills of Shivalik ranges of N-W Himalayas. The objectives of the study were to evaluate the performance of different wheat varieties and their calibration and validation through CERES-Wheat model. The genetic coefficients for three wheat varieties were calibrated and validated with the experimental data. Variety WH 1105 registered higher grain and biological yield followed by HD 2967 and RSP 561. Evaluation with the experimental data showed that performance of CERES-Wheat model was reasonable as indicated by fairly accurate simulations of crop phenology, grain yield, biological yield and various yield attributing parametres against measured data. The values of various model performance indicators like R2, RMSE, nRMSE, MPD, MAE, d-stat, EF and r were in good and excellent ranges.
