Biochemical and morphological basis of jassid (Amrasca devastans Dist.) resistance and inheritance in cotton (Gossypium hirsutum L.)
Four jassid resistant varieties (lines) were crossed with three high yielding adapted varieties (testers) in a Line x Tester fashion to elucidate morphological (trichome density and gossypol gland density) and biochemical (tannin, total phenols and gossypol content) basis of jassid resistance in cotton. The female parent KC 2 recorded high amount of trichome density, gossypol gland density, tannin, total phenols and gossypol content indicating that the parent KC 2 was highly resistant to jassid. Among the hybrids screened, the hybrids KC 2 x MCU 5, KC 2 x MCU 12, KC2 x MCU 7, SVPR 3 x MCU 5 and Khandwa 2 x MCU 12 were found to be moderately resistant under artificial epiphytotic condition. The correlation between jassid susceptibility grade and trichome density, gossypol gland density and tannin content was negative and significant while far between total phenols and gossypol content with jassid susceptibility grade. The inheritance study indicated that resistance in the parents was due to monogenic dominance or digenic interaction. The morphological and biochemical basis of resistance revealed that the high density of trichomes, total phenols, and gossypol gland density constituted the mechanism of resistance in cotton.
Profitability of intercropping system in elephant foot yam with short duration vegetables
Elephant foot yam, “The king of tubers”, is a wider-spaced, long duration crop with immense nutritive and therapeutic values. Its initial growth phase is slower and takes 60 days or more to spread. Thereby its inter-spaces can be utilized to grow short duration vegetables crops. In this regard, field experiments were conducted at Horticultural College and Research Institute, Coimbatore during two different season (2021 and 2022). Here five treatments including mono-cropping of elephant foot yam (CS1) and intercropping of elephant foot yam with cluster bean (CS2), radish (CS3), amaranthus (CS4) and fenugreek (CS5) were taken and replicated four times. The design of the experiments was randomized block design. The intercropping systems in elephant foot yam exhibited higher profit when compared to mono-cropping. The higher gross return of Rs 518950 and Rs. 429750, net return of Rs. 371325 and Rs. 282125 and B:C ratio of 1:2.29 and 1:1.74 was noticed in season I and Season II respectively when cluster bean is inter-cropped in elephant foot yam. Thus, growing cluster bean with elephant foot yam is recommended for higher profitability.
Analysis of the Need for Agricultural Machinery Based on Region and Commodity in Indonesia
The objectives of this study are: 1) To assess the potential uses of agricultural machinery, 2) To identify the number and distribution of government machinery aid in Indramayu, and 3) To need analyze of machinery based on a potential commodity. The results of the descriptive analysis revealed that the level of use of agricultural mechanization for rice cultivation in Indonesia in 2018 was an average of 60.5%, where the level of use of agricultural mechanization in 17 provinces in Indonesia had exceeded the national average. The population of the machineries continues to increase where in 2014 the number was only 12,501 units, but in 2020 the number jumped to 365,328 units. Compared to the availability of machineries, there are quite a lot of gaps, namely for tractor as many as 2565 units, thresher 3834 units and combine harvester as many as 1000 units. The policy recommendation are presented.
Evaluation of chilli hybrids for higher productivity in Madurai District of Tamil Nadu
Chilli is an important spice which is grown throughout India. Chillies are integral and the most important ingredient in many different cuisines around the world as it adds pungency, taste, flavour and color to the dishes. Chilli is grown in sedapatti block of Madurai district in an area of nearly 410 ha. The farmers are mainly growing the local varieties and private hybrids in sedapatti block. During the farmers discussion, the growers opted for new hybrids (high yield, lengthy fruit, good pungency, and colour retention during storage). An Front Line Demonstrations was conducted in mallapuram village of sedapatti block. In this study two varieties (COCH 1 and VNR277 hybrid) were assessed for yield and quality parameters. Chilli hybrid COCH1 recorded maximum crop duration (205 days), Fruit length (11.50 cm), Green chilli yield (26.50 t/ha), Dry chilli yield (5.75 t/ha) and for drying of fruits (9 days). Regarding cost benefit ratio is revealed that chilli hybrid recorded maximum Gross cost (Rs.37,500), Gross returns (Rs. 1,15,750), Net returns (Rs. 78550) and BCR (3.08). Hence in the market hybrid COCH1 fetched more price than the other hybrid.
Assessing spatial heterogeneity of soil properties under sugarcane cropping system using geostatistical models and GIS techniques
The present study aimed to assess the spatial variability and mapping of micronutrients under the sugarcane growing block of the Sivagangai district using geostatistics and the Geographic Information System (GIS). Totally, 100 georeferenced surface samples (0-30 cm) were collected and analysed for soil physicochemical properties. Descriptive statistics showed that the variance values coefficient ranged from 7.32 to 49.83%. Geostatistical analysis was executed for mapping the soil fertility properties with aid of well-fitted semivariogram models. Through cross-validation techniques, the standardized root mean square error (RMSSE) was computed and utilized for good prediction of the model. Geostatistical analysis revealed exponential for pH, EC, Free CaCO3 and B, Circular model for OC and Zn, Spherical for Fe and Mn, and the Gaussian model fitted well for Cu. Multivariate statistics viz., Pearson’s correlation coefficient and stepwise multiple regression were carried out and results showed significant correlations and interrelationships among the soil parameters. The principal component analysis provides the four principal components (PC1, PC2, PC3, and PC4) pertain to eigenvalues > 1 and together elucidated 71.29% of the pattern variance. The kriged map of available Fe, Cu, Zn, Mn, and hot water-soluble B showed areas under deficiency of about 57.3, 52.2,50.2, 44.5, and 83.2%. The spatial variability of various parameters helps in site-specific soil nutrient management and crop planning decisions to enhance sugarcane productivity.
