A field experiment was conducted at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during the year 2014-2016 with ten germplasm of banana viz. Gobin Tulchi (AAB), Bogimonohar (ABB), Manohar (AAB), Agnisagar (AAA). Barjahaji (AAA), Kachkal (ABB), Assamese Malbhog (AAB), Chenichampa (AAB), Bharatmoni (AAB) and Jahaji (AAA) to assess the physiological performance of this banana (Musa spp.) germplasm with special reference to moisture stress. The various parameters were recorded at 5th, 7th and 9th months after planting. The soil of the experimental field was acidic, well drained and sandy loam in texture with low available N and K and medium available P content. The statistical design was Randomized block design. All the data pertaining to the present investigation were statistically analysed as per the method of analysis of variance (ANOVA) given by Panse and Sukhatme (1967). The critical difference (CD) values were calculated at 5 per cent probability level. For analysis software SPSS 7.5, Costat 6.3 and MS-excel were used. Moisture stress progressively reduced the values of leaf area, root biomass, specific leaf weight, fruit length, fruit circumference, duration of fruit filling, number of hands per bunch, number of finger per bunch, pulp-peel ratio and bunch weight. The germplasm Barjahaji was found to be higher yielder followed by Bogimonohar and Agnisagar whereas the cultivar Kachkal and Assamese Malbhog were found to be the lowest performer in this regard. From the above, it can be concluded that the cultivars Barjahaji, Bogimonohar and Agnisagar are physiologically more tolerant.

Five studies were conducted from 1997 to 1999 to determine the effects of subsoiling on root quality (i.e., root length and shape) and on yield of `Beauregard' sweetpotato. The statistical design for all five studies was a completely randomized block design with six replications (four in Goldsboro in 1997). All studies were conducted on Norfolk fine sandy loam soils. Two studies were done in 1997, one in Kinston and the other in Goldsboro, N.C.; two studies in 1998, one in Kinston and the other in Goldsboro; and one in 1999 in Kinston, N.C. Common treatments in the studies consisted of no subsoiling, V shank subsoil, 30 cm below row (56 cm from peaked ridge) and V shank subsoil, 46 cm below row (71 cm from peaked ridge). Roots were longer, had more creases, and were more misshapen due to ripping (regardless of subsoiling depth) in the 1997 Kinston test. No differences were detected in root quality due to subsoiling in the other four tests. Marketable and total yields were increased in both tests in 1997 with subsoiling; however, a similar yield increase was not obtained with subsoiling in 1998 and 1999. Jumbo yields were increased in Kinston in 1997 and Goldsboro in 1998 with subsoiling; the better response was obtained with 30-cm-depth subsoiling. Jumbo yields in 1999 were the same regardless of treatment. Canner and cull yields were similar in all tests across treatments. Yields may be increased with subsoiling in certain circumstances (i.e, drought or soils with hard pans), and can result in more off-shape roots and longer roots. It appears from these studies that yields may be increased with subsoiling; however, more off-shape roots may be produced, especially under dry conditions or where fields are not routinely subsoiled.

The present investigations were carried out on forty genotypes of jackfruit (Artocarpus heterophyllus Lam.) to determine the extent of variability present in the material and association among different traits. The genotypes were collected from six north-eastern states of India viz. Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram and Tripura during the two years 2016 and 2017. Selection and identification of superior genotypes were done following IPGRI jackfruit descriptor. The experiment was laid using randomized block design with three replications during the year 2016 and 2017 under Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, East Siang, Arunachal Pradesh. The phenotypic coefficients of variability and genotypic coefficients of variability were recorded highest values for weight of fresh flake without seed (52.69% & 50.52%, respectively), stalk length (51.09% & 49.06%, respectively) and fruit weight (48.11% & 45.86%, respectively). High heritability coupled with high genetic gain was observed for stalk length, fruit weight, weight of fresh flake with seed and weight of fresh flake without seed traits. Genetic advance was recorded highest for 100-seed weight followed by stalk length and lowest for flake/fruit ratio followed by seed width traits. Yield per plant showed significant and positive genotypic correlation coefficient with fruit diameter, rachis diameter, fruit weight, petiole length, fruit length and flake length traits. The path coefficient analysis revealed that weight of fresh flake with seed has maximum positive direct effect on fruit yield per tree followed by weight of flakes per kg of fruit.

This study aims was to determine the potential of water fern Azolla pinnata combined with biofertilizer (Azotobacter chroococcum N2-fixing bacteria and Pseudomonas cepaceae phosphate solublelizing bacteria) in improving N and P content of the soil, and yield of paddy rice crops. This research was conducted in lowland Sanggar Penelitian Latihan dan Pengembangan Pertanian (SPLPP), Ciparay Bandung regency. The experimental design used was randomized block design with factorial pattern that consists of two factors. The first factor that A. pinnata (A) consists of two levels, without A. pinnata and A. pinnata with as 3 tons ha-1. The second factor is the biological fertilizer (H) consists of 3 levels with doses of 0, 5, and 10 L ha-1. The results showed A. pinnata and biofertilizer do not interact to increased soil N and P, as well as lowland rice crops. However, A. pinnata independently can increase the content of available N and P soil, while the biofertilizer 10 L ha-1 is able to increase the available soil-P content compared with controls. The combination of A. pinnata and biofertilizers have not been able to increase the yield of rice significantly, but can increase the yield of rice by 16.1 % compared to the average yield of rice in paddy field locations in Ciparay Bandung regency

The solubility and availability of Si from the feldspar, silica, and zeolite as Si-bearing minerals were studied in a sandy soil. Silicon uptake by the soybean (<em>Glycine max L.</em>)<em> </em>plant was discussed. The minerals used were applied before planting in two separate rates; rate 1 ≈ 595.2 and rate 2 ≈ 1190.5 kg ha<strong><sup>-1</sup></strong> accompanied by a ≈ 4.8 kg ha<strong><sup>-1</sup></strong> constant rate of the K-humate sprayed as a solution on soil after planting in a complete randomized block design. The dissolved Si from the different minerals at rate 2 followed an opposite direction to their SiO<sub>2</sub> percentage that may be due to the structural differences: silica (1.46 mg kg<strong><sup>-1</sup></strong> - SiO<sub>2 </sub>=98.4%) &lt; zeolite (1.71 mg kg<strong><sup>-1</sup></strong> - SiO<sub>2 </sub>=75.9%) &lt; feldspar (2.09 mg kg<strong><sup>-1</sup></strong> - SiO<sub>2 </sub>= 71.9%). The individual mineral treatments at rate 2 have almost decreased the available NPK estimated after soybean harvesting. The K-humate has enhanced the effect of silica at rate 2 for the available N and P. The soybean seed yield (kg ha<strong><sup>-1</sup></strong>) increased significantly by 117.9% for the S1 + H, 109.2% for K-humate and 57.5% for the Z2 + H. The seeds’ Si (mg kg<strong><sup>-1</sup></strong>) increased significantly from 3.6% to 102.9% affected by the silica treatments.

In the present study, field experiments were performed over 10 consecutive years (2006–15) to assess the effects of biofertiliser and enriched biocompost on soil quality, total organic carbon (TOC) and rice yields in an Inceptisol. Experiments were conducted in a randomised block design with four replicates and five treatments: unfertilised control (T1); recommended doses of inorganic fertiliser (T2); biofertiliser with reduced (50%) inorganic N and P fertilisers (T3); reduced (50%) inorganic N and P fertilisers with 1 t ha–1 enriched biocompost (T4); and reduced (75%) inorganic N and P fertilisers with 2 t ha–1 enriched biocompost (T5). T3 improved soil chemical and biological properties with enhanced soil quality index (40%), total P (23%), total K (42%) and fungal (38%) and bacterial (44%) colony counts. T5 significantly improved the carbon pool index (29%) and available nutrients (N, P and K at rates of 37%, 22% and 10% respectively) and increased soil pH (11%), resulting in a higher sustainable yield index (39%) of rice. Fraction 2 (labile carbon) of TOC, total P, available K, microbial biomass carbon and phosphate-solubilising bacteria were key indicators to assess the suitability of these fertilisers in rice cultivation in north-east India.

Salinity is one of the main plant abiotic stresses which affects the establishment and development crops. Hence, the search for technologies that minimize the damage caused by salinity is essential. The aim of the present work was to evaluate the effect of salinity stress and osmotic conditioning of seeds on the biomass, gas exchanges and chlorophyll pigments in Mesosphaerum suaveolens (L.) Kuntze. The statistical design adopted was a randomized block design, combined according to the Central Composite Design, referring to electrical conductivities of irrigation water and osmotic potentials, with minimum (- α) and maximum (α) values of 0.5 and 10.0 dS m-1 and 0.0 and -1.0 MPa, respectively, totaling nine combinations. The characteristics of dry biomass, gas exchange and chlorophyll indices were evaluated at 45 days after irrigation with saline water started. The salinity of irrigation water severely affected the dry biomass and the gas exchanges of M. suaveolens. Irrigation water of electrical conductivity above 3.2 dS m-1 caused reductions in chlorophyll a, b and total contents in M. suaveolens plants. Seed osmoconditioning did not attenuate the negative effects of saline stress on M. suaveolens plants.
