The study is aimed at delineating groundwater potential zones of the alluvial formations using Dar Zarrouk Parameters and groundwater flow direction on the floodplain. This will help the farmers to utilise the floodplain shallow wells during the dry season farming. Shallow wells on the floodplain of River Benue are the primary sources of water supply for irrigation activities. The floodplain is underlain by Bima sand stones. Twenty-four profiles of vertical electric soundings using Schlumberger array method with the aid of a sensitive ABEM Signal Averaging System (SAS) was used to investigate. The results were then compared with the alluvial floodplain lithologies at each sounding points with resistivity values ranging between 0.146 Ωm to 9,873.6 Ωm and depths varying from 0.2 to 38.33 m. The geoelectric sequence of the alluvial formations of the floodplain reveals semi aquifer system. The aquifer hydraulic characteristics indicated that the transverse resistance, R ranged between 2,626.70 Ωm2 to 241,252.38 Ωm2 with a mean value of 45,172.17 Ωm2. The longitudinal conductance, S ranged between 0.001 to 0.221 with an average value of 0.036. The hydraulic conductivity value across the floodplain ranges between 0.21 m/day to 29.06 m/day with a mean value of 11.22 m2/day. The transmissivity values obtained for the various layers ranges between 1.68 m2/day to 808.16 m2/day with an average value of 214.07 m2/day. Three groundwater potential zones were delineated on the floodplain. The results of the hydraulic head reveal that the water levels in the floodplain are higher than the River and recharge the River.

A study was carried out in model grapevine orchard of department of Horticulture at Kralbagh, Tehsil Lar, district Ganderbal (J&K) for two consecutive years. The treatment consisted of 3 levels of fertilizer doses, F1(FYM50 kg/vine + recommended dose of NPK: 555, 227, 470 g/vine), F2(FYM 50 kg/vine+ 2 times recommended dose of NPK: 1110, 454, 940 g/vine), F3(FYM 50 kg/vine+ 3 times recommended dose of NPK: 1665, 681, 1410 g/vine), 3 micronutrients viz. M1(Solubor 0.1%), M2(ZnSO4 0.4%) and M3(Solubor 0.1% + ZnSO4 0.4%) applied two weeks before bloom and their combinations replicated thrice with a double plot size in a completely randomized block design. Fertilizer level F2  recorded maximum percentage of fruitful shoots per, number of bunches per vine, fruit yield, berry TSS, berry total sugars, berry anthocyanin contents and lowest berry titrable acidity and shot berries during both the years. Among micronutrients, M1resulted in highest percentage of fruitful shoots per vine, number of bunches per vine, fruit yield, bunch weight, bunch diameter, berry weight, berry length, berry diameter, berry juice, berry TSS, berry total sugars, berry anthocyanin content and lowest berry titrable acidity and shot berries during both the years of study. Combination of fertilizer level F2 and micronutrient M1 resulted in highest percentage of fruitful shoots per vine, number of bunches per vine, fruit yield, berry TSS, berry total sugars, berry anthocyanin content and lowest berry titrable acidity and shot berries during both the years under study. Thus  it could be concluded that fertilizer dose F2(FYM-50 kg/vine + 2 times recommended dose-NPK: 1110, 454, 940 g/vine), micronutrient M1(Solubor 0.1%) and their combination was most effective for improving growth, yield, quality and lowering shot berry incidence of grape cv. Sahebi.

DOI: 10.9734/CJAST/2018/41524

This study was aimed at assessing and comparing the quality of groundwater for safe use in two geologic formations (Basement complex and sedimentary) of Katsina State, Nigeria. A total of twenty (20) boreholes; ten (10) from each formation were selected at random from various locations across the state. The water samples from these boreholes were analysed for 13 physicochemical and bacteriological parameters in order to ascertain their level and confirm wether they meet the World Health Organisation (WHO) standards for drinking water [12].

The Mean levels of Total alkalinity, Sulphate and magnesium were above WHO limit in Basement complex samples while; the mean concentration of iron in the sedimentary zone was above WHO limit. There was a significant difference (<0.05) in the Chloride and TDS concentration between the two formations. Most of the samples analysed met the requirement for drinking water, probably due to the natural filtration process the water has undergone.

The study was conducted with the prime objective to generate a stochastic time series model, capable of predicting runoff in Dachigam catchment area of Dal lake. It covers an area of 141 sq. km. The runoff data of the catchment from the year 1993-2013 was collected and used for the generation of model. Autoregressive (AR) model of order, 1 were used for annual runoff series and different parameters were estimated by the general recursive formula. The goodness of fit and adequacy of models were tested by Box-pierce portmanteau test, Akaike Information Criterion and by comparison of historical and simulated graphs. The AIC value of runoff for AR (1) was model (326.35) which is satisfying the selection criteria. The mean forecast error is also very less in case of runoff AR (1) model. On the basis of the statistical test, Akaike Information Criterion the AR (1) models with estimate model parameters can be used efficiently for the future predictions in Dachigam Catchment. The graphical representation between historical and generated correlogram has also proved that there is a very close agreement between simulated and observed runoff. The coefficient of determination Rfor runoff AR (1) model is 0.98.The comparison between the measured and simulated run off by AR (1) model clearly shows that the generated model can be used efficiently for the prediction of runoff in Dachigam Catchment, which can benefit the farmers and research workers for water harvesting, ground water recharge, flood control and development of their water management strategies.

The productivity of guava is presently much below the productive potential, due to traditional practices and prevalence of old and unproductive orchards with declining yield efficiency. Moreover, large trees take several years before they come into bearing and overall cost of production per unit area is further increased. The hi-tech and Innovative methods which include high planting density have been identified to increase guava production in India in order to be competitive in world market. The response of guava to training and pruning for canopy modification is well known. It is one of the most suitable for high planting density, as it bears on current season’s growth and responds to pruning. Modifications in pruning and training techniques influence plant spacing and production decision. Similarly, unpruned tall and crowded guava trees pose a number of problems while carrying out various cultural operations. Guava has a higher proportion of ‘shade’ to ‘sun’ leaves and their leaves are found photosynthetically inactive under deeper shade and act as unproductive sink. Therefore, vegetative growth, fruit yield and quality are functions of light interception and translocation of light energy into chemical energy. Quality fruit is function of absorption of light and light is directly proportional to the yield of fruit trees. In the present, high-density plantation with managed canopies is the need of the hour to achieve high productivity per unit area.
