Abstract

A field experiment was conducted to study the effect of different levels of drip irrigation along with various fertigation levels in fennel (Foeniculum vulgare Mill.) during Rabi season of 2010-11 at Swami Keshwanand Rajasthan Agricultural University, Bikaner. The experiment consisted of twenty one treatment combinations comprised of seven drip irrigation treatments (l 00: 100: 100 per cent ETc, 80:80:80 per cent ETc, 60:60:60 per cent ETc, 40:40:40 per cent ETc, 40:60:60 per cent ETc, 40:80:80 per cent ETc and 40: 100: 100 per cent ETc at three different development growth stages and three levels of fertigation (50, 75, 100 % recommended dose of N and P). The experiment was laid out in Split - Plot Design with three replications. Irrigation through drip was applied on the basis of ETc levels i.e. PE Kp Kc considering Kc values to be 0.70, 1.05 and 0.90 for initial (25 days), crop development (90 days) and final (35 days) stages, respectively. The fertigation was applied in six split doses at an interval of 15 days after sowing. Investigation results revealed that the the growth, flowering, yield and WUE of fennel significantly increased with different irrigation and fertigation levels. The maximum plant height (141.56 cm), number of branches per plant at 50 per cent flowering (39.22), diameter of main umbel (19.01 cm), dry matter of plant (34.46), biological yield (110.78) and test weight (8.58) were recorded under the treatment of 100 per cent Etc., whereas number of umbels per plant (21.40), number of umbellates per umbel (11.13), number of seeds per umbellate (10.63), seed yield (18.45 q ha-1) and WUE (0.542 q ha-1 cm) were recorded maximum under the treatment of 80 per cent ETc. level. However, the 100 per cent fertigation level was recorded highest plant height (108.52 cm), number of branches per plant at 50 per cent flowering (29.10), number of umbels per plant (18.25), diameter of main umbel (14.65 cm), dry matter of plant (27.33), number of umbellates per umbel (8.34), number of seeds per umbellate (8.17), seed yield (14.39 q ha-1), biological yield (62.50), test weight (7.83 g) and WUE (0.356 q ha-1 cm).

Abstract

A field experiment was conducted to study the effect of farm yard manure (FYM) and boron on growth and yield of Bael (Aegle marmelos) during, 2011-12. The results revealed that application 100 kg FYM significantly increased plant growth. Maximum fruit yield and its parameters recorded maximum viz., fruit weight (971.83 g), fruit yield (20.40 kg) and number of fruit (23.0) however, fruit cracking (4.41 %) was recorded minimum with application of 50 kg FYM. Quality parameters like TSS, sugar and ascorbic acid were also found maximum under this treatment. Application of foliar spray of borax 0.6 per cent was significantly increased fruit weight (962.0 g) and fruit yield (21.21 kg). Whereas, minimum fruit cracking (2.14 %) and peel thickness (2.41 mm) were also observed with application of 0.6 % borax. This treatment also improved quality parameters of fruit. The combined effect of FYM (50 kg tree-1) and foliar spray of borax 0.6 per cent was found significant pertaining to gain in tree height (49.20 cm), stem girth (2.75 cm), fruit weight (980.0 g) and fruit yield (36.34 q/ha) compared to control.

Abstract

The note deals with the occurrence of andalusite-garnet-bearing rock from Daroji area, its geological setting, petrographic description and relationship with the other meta-sediments. Its occurrence at the borders of the Thorangallu granite indicates that its development in the contact zone is due to thermal metamorphism.

Abstract

In the Rajpura-Dariba belt zinc and lead mineralization was established on the basis of gossan and opinions were given that the deposits are stratiform and syngenetic. During last two decades metamorphism and volcanic processes have been attributed for the generation of exhalative and remobilized lead-zinc ore bodies. Subsequent exploration was based on the concept of successive borehole planning around positive intersections. Areas having surface indications of base metal mineralization and their extensions have been already explored. Recent deep drilling by Hindustan Zinc Limited (HZL) in this area has intersected rich ore lodes, thereby confirming depth ward continuity of ore zones at some places. It indicates possibility of searching hidden deposits by innovative techniques. Therefore, today, there is a challenge before geoscientists to discover new deposits in this area by an exploration technique which should have low risk, consume less time and it should be cost effective.

In view of the above objective for Rajpura-Dariba belt, an integrated method of exploration has been discussed. The exploration strategy is based on synthesis of all the available data and its reinterpretation to prognosticate favourable sites of exploration and also to suggest new scheme of exploration. Based on previous data and present studies structural and lithological controls of base metal mineralization have been recorded and guides for searching new areas and exploration strategy has been suggested.

Based on these data six new areas have been identified for future exploration. The data includes lithological configuration, structural setup and controls of lead-zinc mineralization collected from previous data and present studies. It is suggested that for further exploration in these six areas ground magnetic survey should be carried out to understand magnetic lows and highs to decipher structural discontinuity and faults which could be favourable sites of mineralization. Combination of SP, IP, EM and gravity shall help in distinguishing between base metals from graphite mica schist.

Abstract

All practical real-time scheduling algorithms in distributed processing environment present a trade-off between their computational complexity and performance. In real-time systems, tasks have to be performed correctly and timely. Finding minimal schedule in Distributed Processing System (DPS) with constraints is shown to be NP-hard. Although some optimal algorithms have been employed in uni-processor systems, they fail when they are applied in multiprocessor systems. To alleviate these deficiencies, in this paper a fuzzy logic approach is discussed to determining the Optimal Busy Time (OBT) of the DPS considering the Execution Time (ET) and Inter Task Communication Time (ITCT) as input parameters. The complexities of the processing Time of tasks on processors and ITCT between the tasks and the imprecision of linguistic expressions are taken into consideration. In varying conditions of ET and ITCT parameters, the maximum value of OBT likely to be changes accordingly that depends on the inference engine mechanism. A detailed exposition of the application combining linguistic approach to optimize OBT considering heterogeneous environment is presented in this study.

Abstract

Distributed Systems is a mean to run multiple transactions simultaneously. In distributed systems, while dealing with real-time assignments, tasks have to be scheduled correctly and timely. All practical real-time scheduling algorithms in distributed systems present a trade-off between performance and computational complexity. This is mainly due to the complex nature of Mathematical models. In comparison, fuzzy is a simplified approach that optimizes the complete system that too with less time complexity. Further Fuzzy approach produces results that are closer to real world problems. The most innovative part of the research is that reliability metrics have been taken as the major parameter for decision for scheduling. The priority is computed based on the values of Failure rate, CPU time and Reliability. The problem has been simulated on MATLAB 7.0.4 Mamdani Fuzzy Inference Engine to evaluate the performance of the proposed methodology. Experimental results have shown that the proposed fuzzy scheduler creates feasible schedules for homogeneous and heterogeneous tasks.

Abstract

In this paper, the authors have considered a coded cooperative based multi-relay Device to Device (D2D) system for underlay 5G cognitive radio networks. The Coded cooperation, a cooperative relaying technique is an attractive choice for bandwidth efficiency and better connectivity. The Outage Probability expression is derived for the proposed system considering the interference limit between the secondary D2D user system and the primary user system over the Nakagami-m fading channel. The effect of the channel parameter and number of relays (M) on the outage performance is also studied.

Abstract

A field experiment was conducted at C.C.S. HAU, Regional Research Station, Bawal to evaluate the effect of phosphorus and sulphur fertilization on fodder yield and quality of cowpea (Vigna unguiculata). There was significant increase in green and dry fodder yield with increase in S levels from 0 to 40 kg/ha. Similarly, with increase in P₂O₅ level from 0 to 60 kg/ha, there was significant increase in green and dry fodder yield of cowpea. Application of 60 kg/ha P₂O₅ with 40 kg/ha S resulted in maximum green and dry fodder yield of cowpea as compared to other treatment combinations. Crude protein, ether extract and ash content were increased with each increment of P₂O₅ and S levels while crude fiber and nitrogen free extract showed reversed trend.
