Abstract The only crop providing raw materials for sugar and jaggery production in Nepal is sugarcane, and its introduction and adaptation is the only route for its development commercially. Therefore, this research was carried out to check its adaptability and yield potential in National sugarcane research Station, Jitpur, Bara, and in different parts of the country, which were tested as Initial evaluation Trial just after the introduction, and then experimented as Advanced Varietal Trial, Coordinated Varietal Trial, and Coordinated Farmers Field trial simultaneously from the year 2012/13 to 2017/18. The method used was RCBD with three replication in every of the trial. Analyzing all the cane yield attributing characters, and ratooning potential and ratoon yield, Co 0232, CoLk 94184 and CoSe 03234 were found superior to all other tested genotypes. Similarly, sugarcane juice quality (sugar recovery, CCS (t/ha) & Sucrose %) were found significantly higher in these three genotypes, so these genotypes Co 0232, CoLk 94184 and CoSe 03234 were registered in gadgets of Nepal Government as variety Jitpur-5, Jitpur-6 and Jitpur-7 respectively.

The foliar application of nutrients help the plant leaves to readily absorb the applied nutrients through the nutrient solution and increases the nutrient use efficiency and thus improves the crop yield. The field experiment was conducted for two consecutive years to find out the affect of foliar spray of NPK and micronutrient on cane yield, yield parameters and juice quality of sugarcane during 2019-20 and 2020-21.The present study was carried out on clay loam soils of Research farm of Regional Research Station, CCS Haryana Agricultural University, Karnal, Haryana. The research revealed that cane yield and yield parameters i.e., cane length, and cane weight was significantly affected with the foliar spray of NPK and micronutrient but non-significant effect was observed for cane girth and number of internodes. With respect to juice quality parameters viz., commercial cane sugar (CCS) %, pol % and sugar yield, significantly affected with foliar spray of NPK and micronutrient. The highest cane yield, cane weight and cane length was recorded with the foliar application of 2% NPK (19:19:19) + 0.5% ZnSO4 +1% FeSO4 (78.16 t/ha, 1.21 kg and 207.3 cm) followed by foliar spray of 0.5% ZnSO4 + 1% FeSO4+ 2.5% urea recorded 76.75 t/ha, 1.20 kg and 207.1 cm, respectively. The lowest cane yield (70.68 t/ha) was recorded with the application of recommended dose of fertilizer (RDF) alone. The highest CCS % (12.16), pol % (17.36) and sugar yield (9.51 t/ha) was observed in the treatment 2% NPK + 0.5% ZnSO4 +1% FeSO4. Thus, foliar application with NPK and micronutrient could significantly improve the cane yield, yield parameters and juice quality of sugarcane crop.

An experiment was conducted to study the effect of crop geometry and irrigation levels on sugarcane under drip irrigation at Main Sugarcane Research Station, Junagadh Agricultural University, Kodinar during 2011-14. The treatment consisted of three crop geometry (90 cm normal planting, paired row planting (60: 90 cm) and paired row planting (60: 120 cm) and three drip irrigation levels (0.5 PEF, 0.7 PEF and 0.9 PEF) and with an extra treatment (control) having surface irrigation (90 cm) at 1.0 IW/CPE ratio. Experimental results indicated that paired row (60: 90 cm) planting gave significantly higher cane yield (101.04 t/ha) over 60: 120 cm paired row planting (88.82 t/ha) and remained at par with 90 cm row spacing (97.34 t/ha). Drip irrigation level of 0.9 PEF gave significantly higher cane yield (108.63 t/ha) over 0.7 PEF (96.01 t/ha) and 0.5 PEF (82.56 t/ha). Juice quality parameters like brix, sucrose, purity and sugar recovery percent were not affected significantly due to either crop geometry or different drip irrigation levels. Significantly higher cane yield was recorded under drip irrigation (95.74 t/ha) compared to surface irrigation (76.86 t/ha). The total water use was not affected due to different crop geometries. Water use decreased constantly in 0.7 and 0.5 PEF compared to 0.9 PEF and accordingly WUE increased.

Evaluation Trial

The objective of this study was to evaluate the potential of recurrent selection for improving seed yield in a soybean population. Seventeen parents, chosen for their high yield potential in the sub-tropical environments of Southern and Central Queensland were intermated using a diallel cross mating system. F1 plants were intercrossed in pairs for two more generations and then allowed to self for two generations to produce the base population. The selection criterion was the seed yield of S1 lines grown at Hermitage Research Station. The selection intensity was approximately 10%. After five cycles of recurrent selection the mean yield of the population and the mean yield of the lines selected for recombination had improved by 17% and 54% respectively, in comparison with one of the original parents, Davis. Progress from recurrent selection was evaluated using fifty randomly selected lines from the base population and from each of the first three cycles of selection. The average gain per cycle in seed yield, averaged over five sites was 128 kg ha-1 or 5.4% of the yield of the base population. Greater progress (9.8% per cycle) was measured at the testing site for selection (Hermitage Research Station) which was heavily infested with phytophthora root and stem rot than at three other sites (2.7% per cycle) which has nil or low levels of disease. Broad sense heritabilities for the base population and for cycles 1, 2 and 3 in the evaluation trial were 0.34, 0.25, 0.13 and 0.14 respectively compared with a mean heritability of 0-64 for the first five cycles of the selection experiment. Expected gain from further cycles of selection was estimated at 102 kg ha-1 per cycle for three replicates at a single site. In the evaluation trial correlated responses to selection for yield were found in a number of other traits. Days to flowering was reduced by 0.8 days/cycle while days to maturity increased by 1 day/cycle. Seed shattering score was significantly reduced from 0.98 to 0-69 while there were only minor changes in plant height, lodging and seed coat quality score. Resistance to root and stem rot and seed coat mottling, due to primarily to soybean mosaic virus, were also significantly increased. The improvement in phytophthora resistance was expected as the field used for S1 yield testing had become infested with the disease. A covariate analysis indicated that about half the improvement in seed yield at the Hermitage site was due to the correlated response of increased resistance to phytophthora root and stem rot.

Tender Coconut

Coconut water is considered as nature’s gift to mankind due to its health benefits. The steady demand for tender coconut is currently met from a local dwarf from Kerala, viz., Chowghat Orange Dwarf (COD). However, there is a need for diversification of genotypes. Based on a 20-year-old germplasm evaluation trial conducted at Coconut Research Station (CRS), Aliyarnagar, a selection from Kenthali Dwarf (KTD) has been identified as a promising genotype exclusively for tender nut purpose. It has been released as TNAU coconut ALR 3. The selection is an early flowering genotype that comes to flowering from the third year onwards. The average yield potential is 86 nuts per palm per annum from the stabilized bearing period onwards, with a maximum yield potential of 121 nuts per palm per annum. This accounts for 34.1% and 37.9 % increase in yield over COD and MYD. Tender nut water analysis revealed that the genotype possessed 5.2% soluble sugars with a high potassium level (190.21) compared to COD and MYD. The variety is recommended for irrigated belts of Tamil Nadu.

Analytical Tools

Ceramic objects in whole or in fragments usually account for the majority of findings in an archaeological excavation. Thus, through examination of the values these items bear, it is possible to extract important information regarding raw materials provenance and ceramic technology. For this purpose, either traditional examination protocols could be followed, focusing on the macroscopic/morphological characteristics of the ancient object, or more sophisticated physicochemical techniques are employed. Nevertheless, there are cases where, due to the uniqueness and the significance of an object of archaeological value, sampling is impossible. Then, the available analytical tools are extremely limited, especially when molecular information and mineral phase identification is required. In this context, the results acquired from a multiphase clay ceramic dated on Early Neopalatioal period ΜΜΙΙΙΑLMIA (1750 B.C.E.–1490 B.C.E.), from the Minoan Bronze Age site at Philioremos (Crete, Greece) through the application of Raman confocal spectroscopy, a nondestructive/ noninvasive method are reported. The spectroscopic results are confirmed through the application of Xray microdiffraction and scanning electron microscopy coupled with energy dispersive Xray spectrometry. Moreover, it is demonstrated how it is made possible through the application of microRaman (μRaman) spectroscopy to examine and collect crucial information from very small inclusions in the ceramic fabric. The aim of this approach is to develop an analytical protocol based on μRaman spectroscopy, for extracting firing temperature information from other ceramic finds (figurines) where due to their uniqueness sampling and analyses through other techniques is not possible. This information can lead to dating but also to firing kiln technology extrapolations that are very significant in archaeology.

SUMMARYAhipa is a legume of great interest for the production of raw materials (starch, sugar, oil and proteins) for industrial use. Its yield potential and ability to fix atmospheric N2 in association with rhizobia makes it an attractive option for low input agriculture systems. At present, it is cultivated on a very small scale as a food crop in a few South American countries. Little information is available on symbiotic N2 fixation in ahipa and no work has been performed on strain selection for inoculant production. Soils in southwest Europe are devoid of specific rhizobia able to nodulate on ahipa. Selecting rhizobia for symbiotic effectiveness from a collection led to the isolation of strains which provided greater shoot growth and N content under controlled conditions. In the field, inoculation at sowing with the selected strains increased significantly seed and tuberous root yield and seed protein content. The amount of N2 fixed, estimated by 15N natural abundance, reached 160–260 kg N ha−1. In previous work, ahipa appeared to be a promising alternative crop for the production of industrial raw materials. The results of the present study showed a yield increase in tuberous roots and seeds when applying effective rhizobia inoculants. Furthermore, a positive soil N balance was left after its cultivation making ahipa even more interesting for sustainable farming systems.

Yield and quality performances of three jackfruit genotypes were studied at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Pahartali, Chittagong during 2013-2014. Age, growth, maturity period, yield potential and also qualitative characteristics were compared among them.  Based on overall performance with respect to bearing potential, maturity period, fruit and bulb characters, the genotypes AHPah-1 have been found promising for table purpose followed by AHPah-2 and AHPah-3. Minimum days (117) to 1st harvest were observed in AHPah-1. The number of fruits per plant was exceedingly higher (73) in AHPah-1 whereas minimum number (41) was found in AHPah-2. Maximum weight (8.40 kg) per fruit was observed in AHPah-2 and minimum was in AHPah-1(3.40 kg).  The highest single fruit length (37.25cm) was found in AHPah-2 and breadth (27.00cm) was produced by AHPah-3. Maximum number of bulbs (116) was produced in AHPah-1, whereas minimum (63.00) was in AHPah-3. Maximum weight of bulbs per fruit (4.24 kg) was produced in AHPah-2. Individual bulb weight was higher (54.42g) in AHPah -2 whereas, the lowest (16.71) was in AHPah-1. Edible portion was higher (69.27%) in AHPah-1 whereas, the lowest (53.43%) was in AHPah-3. The TSS was the highest (21.00%) in AHPah-1. The highest bulb length and breadth was found in AHPah-3. Highest seeds weight (639g) was produced in AHPah-2. Individual seed weight (8.19 g) was higher in AHPah-2. Therefore, the genotypes can be included in the variety development program after comparing with the already BARI released jackfruit variety.The Agriculturists 2016; 14(1) 107-111
