A field experiment was conducted during rabi, 2021-22 at Agricultural College Farm, Bapatla to assess the response of macro and micronutrients on growth and yield of groundnut in coastal sandy soil. The experiment was laid out in RBD with seven treatments replicated thrice. The treatments are T1- Control, T2- 100% RDF, T3- 125% RDF, T4- 100% RDF + Soil application of ZnSO4 @ 50 kg ha-1 and Borax @ 10 kg ha-1, T5- 125% RDF + Soil application of ZnSO4 @ 50 kg ha-1 and Borax @ 10 kg ha-1, T6- 100% RDF + Foliar application of ZnSO4 @ 2 g L-1, FeSO4 @ 5 g L-1 and Borax @ 1.5 g L-1 at 45 and 65 DAS, T7- 125% RDF + Foliar application of ZnSO4 @ 2 g L-1, FeSO4 @ 5 g L-1 and Borax @ 1.5 g L-1 at 45 and 65 DAS. The results indicated that there was a significant influence on dry matter production, number of pods per plant and yield and quality parameters such as oil yield and protein content by the application of macro and micronutrients. The maximum dry matter accumulation, number of pods per plant, haulm, pod and kernel yield were obtained by the treatment T7 which received 125% RDF + Foliar application of ZnSO4 @ 2 g L-1, FeSO4 @ 5 g L-1 and Borax @ 1.5 g L-1 at 45 and 65 DAS. However, the growth parameters such as plant height, number of primary branches, number of compound leaves and yield attributes such as shelling percentage and 100- kernel weight and oil content were not significantly influenced by the macro and micronutrients application.
The present investigation was conducted at Agronomy Research Farm at ANDUA&T, Kumarganj, Ayodhya (U.P.) during Zaid season of 2021 to asses the planting geometry with phosphorus levels on growth and yield of summer moong. The twelve treatments were tested in Factorial Randomized Block Design with three replications keeping three planting geometries viz.,30 cm x 10 cm, 30 cm x 15 cm, 30 cm x 20 cm and four phosphorus levels viz., 0, 20, 40 and 60 kg/ha. The soil of field was silty loam and the pH of soil was 8.3. The summer moong variety of NDM-1 was sown on 16-04-2021 with seed rate of 20 kg/ha. and the crop was harvested on 25-07-2021. Results revealed that the growth attributes viz., plant population, plant height, dry matter accumulation, branches per plant and leaf area index were significantly higher at 30 cm x 15 cm planting geometry over rest geometry, respectively in summer moong. The yield attributes as number of pods per plant, length of pods, number of grains per pod and number of grains per plant were significantly superior in summer moong crop at 30 cm x 15 cm planting geometry compared to 30 cm x 10 cm and 30 cm x 20 cm planting geometry, respectively. The planting geometry of 30 cm x 15 cm were proved significantly superior in terms of seed, straw and biological yield and harvest index when compared to the rest of treatments, respectively. The increment percentage in seed yield of 10.15% and 6.34% compared to 30 cm x 10 cm and 30 cm x 20 cm planting geometry, respectively. The plant height, dry matter accumulation, branches per plant and leaf area index were found significantly superior upto 40 kg/ha, phosphorus over rest planting geometries, respectively except number of branches per plant upto 60 kg P2O5 /ha. The number of pods/plant, length of pods, grains/pod and grains per plant were significantly increased upto 40 kg P2O5 /ha over rest used phosphorus doses, respectively. The highest seed yield, straw yield biological yield and harvest index were recorded significant upto 40 kg/ha phosphorus over 0, 20 and 60 kg/ha P2O5, respectively and increased phosphorus levels at 60 kg/ha at par in respect harvest index only. The increment evaluated in grain yield of summer moong (37.16% and 20.72%) over control and 20 kg/ha phosphorus, respectively. Therefore, the planting geometry of 30 cm x 15 cm with used 40 kg/ha phosphorus were better performance in terms of growth and yield attributes and yields of summer moong in present field experimentation.
Rice blast (Pyricularia oryzae) is the most destructive disease of rice in Jammu & Kashmir. The variability status of P. oryzae was not studied in Jammu region, although many studies had been done in the Kashmir region, therefore the present study is first study which aimed at determining the cultural variability in the rice blast isolates of the Jammu region. In this research, leaf blast samples were collected from the rice growing areas of five districts of Jammu division and variability among 30 isolates of Pyricularia oryzae was studied with respect to cultural traits. The colony colour of thirty isolates collected during the survey were off white to greyish black, with circular or irregular margins and flattened to raised growth pattern. On the basis of colony growth pattern, margin and colour, the isolates were categories into 6 groups (A, B, C, D, E and F). All thirty isolates exhibited excellent variability in respect of colony growth pattern, margins and colony colour.
Sesame root and stem rot incited by Macrophomina phaseolina is polyphagous a soil borne and phytopathogenic fungus having a wide host range of about 500 cultivated and wild plant species worldwide. In the present study efforts were made to find out the sources of promising breeding cultivar/varieties to root and stem rot of sesame. In present investigation comprised of 314 cultivars of sesame including two local checks GT-10(resistant) and VRI-1(Susceptible) were used for rapid screened by sick pot method against Root and stem rot against M.phaseolina. Among 314 cultivars results were observed seven cultivars were recorded between 15-20 per cent and 35 cultivars recorded between 21-30 percent root and stem rot incidence.
This study aimed at assessing the level of livelihood diversification and its determinants in the Uttarakhand hills using the Simpson diversification index and a multiple linear regression model from the data obtained from 200 sample farmers chosen through a multistage random sampling technique. The results indicated that there was 100 per cent engagement of households in agricultural activities, yet the proportion of average income derived from them was only 4.78 per cent. The value of the diversification index indicated that about 19 per cent of the sample households belonged to low, 49.50 per cent to moderate, and 31.50 per cent of households belonged to a high level of livelihood diversification. Further, the results of the multivariate regression equation indicated that household structure, dependency ratio, education of household, organisation membership, and training had positive effects, while age of household head and farm size showed negative effects on livelihood diversification. As the soil and topography in the state are not suitable for mono-cropping, mixed agricultural practises need to be adopted. Small scale industries, cottage industries, and tourism should be developed and have diverse skill development training programmes.
