Interleave division multiple access (IDMA) is a recently proposed technique for multiple access communications, which is known for property of orthogonality amongst its user-specific interleavers. In IDMA systems users are separated by user-specific chip-level interleavers unlike conventional CDMA scheme. The interleavers are therefore referred as the heart of IDMA transceivers. Thus, the interleaver must be carefully designed to ensure good performance, low memory requirements and low computational complexity. Interleaver for IDMA systems are generated using two different approaches, random approach and non-random approach. Both the approaches have distinct characteristics. In random approach Bit error rate is favored and in non-random approach memory requirement is favored. In this paper we propose a new interleaver technique named indexed random interleaver based on random generation approach. Simulation results show that the proposed interleaver gives better average bit error rate performance than conventional random interleaver.

A field study was conducted to collect the information on calf management practices followed by the dairy animal owners of Navsari district of South Gujarat. Two hundred respondents of 10 villages having elite dairy animals were included in the study. Majority of respondents (97.67%) of Navsari district attended calving and took care of the calves after parturition while only 2.33 per cent of the respondents didn’t do so. Barring 3.5 per cent of the respondents of rural area all others in rural as well as in urban areas attended calving and took care of the calves after the parturition. It was found that majority of the (83%) respondents cleaned the calf soon after calving and remaining 17 per cent of the farmers didn’t followed this practice. The practice of cleaning of the calves just after calving was practiced by 74.5 per cent of the rural and all respondents of the urban areas.Around 40.5 per cent of rural and 61 per cent of the urban respondents allowed the calves to suckle their dams before expulsion of placenta whereas 59.5 (rural) and 39 (urban) per cent of respondents allowed the calves to suckle their dams only after the expulsion of placenta.Keywords

A field experiment was conducted at Hi-tech Horticulture Park, Department of Horticulture, Junagadh Agricultural University, Junagadh during Late Kharif season in the year 2010 with mulch to study the effect of planting geometry on yield and quality of watermelon. It consists of twelve treatment combinations, comprising of three levels of planting geometry viz., diagonally paired row with 80 cm spacing (G1), parallel paired row with 80 cm spacing (G2) and parallel paired row with 40 cm spacing (G3) were embedded in a Split Plot Design in CRD with four replications. The experiment resulted that with maximum yield and quality attributing characters under study were significantly affected by planting geometry treatments. Highest fruit length (21.25 cm), fruit girth (13.81 cm), yield tons per hectare (44.33 t/ha), pulp weight (1712.57 g), lowest rag weight (610.90 g), total soluble solids (10.98 °B), non-reducing sugars (3.91 %), reducing sugars (1.72 %), total sugars (5.25 %) and ascorbic acid content (7.90 mg/100 g pulp) were recorded under G1 (Diagonally paired row with 80 cm spacing). While, superior fruit yield in terms of kg per plot (38.38 kg) was found in G3 (Parallel paired row with 40 cm spacing).Keywords

A field experiment was conducted in polyhouse at Hi-tech Horticulture Park, Department of Horticulture, Junagadh Agricultural University, Junagadh during Late Kharif season of the year 2010 with mulch to study the effect of retention of fruits on yield and quality of watermelon. It consisted of twelve treatment combinations, comprising of four levels of fruit retention viz., 2 fruits/plant (F1), 3 fruits/plant (F2), 4 fruits/plant (F3) and control (All fruits were retained) (F4) were embedded in a Split Plot Design in CRD with four replications. The experiment result were highest average fruit weight (2.57 kg), yield tons per hectare (45.27 t/ha), maximum pulp weight (1706.56 g), total soluble solids (11.18 °B), non-reducing sugars (3.95 %), reducing sugars (1.70 %), total sugars (5.29 %) and ascorbic acid content (7.86 mg/100 g pulp) was found in case of F2 (3 fruits per plant). While, maximum fruit length (21.29 cm), fruit girth (13.84 cm) and lowest rag weight (612.66 g) was observed in case of F1 (2 fruits per plant). Whereas, maximum fruit yield in terms of kg per plot (36.76 kg) and number of fruits per plot (18.66) was recorded in case of F3 (4 fruits per plant).Keywords
