Floral Biology and Pollination Dynamics of Newly Introduced Apple (Malus × Domestica Borkh.) Varieties
Apple is renowned for its nutritional as well as economical value. The success of newly introduced apple varieties highly depends on a clear understanding of their floral biology and pollination behaviour, which are crucial for ensuring optimal fruit set, yield and quality. Therefore, the present investigation was carried out at Regional Horticultural Research and Training Station, Mashobra, Shimla, Himachal Pradesh, India during the year 2023 and 2024 to study the floral biology of different apple varieties and to study the extent of fruit set under different modes of pollination. Five main varieties viz. Red Velox, Red Cap Valtod, Jeromine, Scarlet Spur II and Modi along with three pollinizing varieties viz. Auvil Early Fuji, Dark Baron Gala and Redlum Gala were selected for different studies. Marked variations in the floral characters like flower size, petal arrangement, stamen number, pistil length and ovary diameter were recorded. Flowering duration was longest in Dark Baron Gala (15 days) during 2023 and 2024 and shortest (10 days) in Scarlet Spur II and Red Velox in both years. Maximum (88.78 %) mean pollen viability was observed in 1 per cent acetocarmine and minimum (87.70 %) in erythrosine B. In vitro pollen germination was maximum (61.83 %) in Dark Baron Gala and minimum (40.86 %) in Scarlet Spur II. Average fruit set was found to be highest (63.66 %) under open pollination conditions followed by controlled/hand-pollination conditions (51.13 % and 53.85 %) during 2023 and 2024 and lowest (22.33%) under bagging. Similarly, mean fruit retention was highest (73.14 %) under open pollination conditions followed by controlled/hand pollination conditions (54.90 % and 69.42 %) during 2023 and 2024 and lowest (59.05 %) under bagging. Maximum values of fruit length, breadth and weight were recorded under bagging condition followed by open pollination, whereas, minimum fruit length, breadth and weight under controlled/hand pollination conditions. On the basis of present investigation Dark Baron Gala showed all the characteristic of ideal pollinizing variety viz. synchronization in flowering, pollen viability, pollination behaviour and extent of fruit set with over all commercial accessibility.
Impact of integrated nutrient management on micronutrients uptake in pearl millet-wheat cropping system under saline water irrigations
The combination of organic manures and fertilizers played a crucial role in improvement of soil physico-chemical properties, transformation and distribution of macro and micro-nutrients under various cropping system. The non-availability of good quality water for irrigation especially in arid and semi-arid regions of Haryana led to development of soil salinity that interferes with sustainable crop production. The study was conducted with the aim to explore the appropriate combination of manures and fertilizers under such conditions in pearl millet-wheat cropping system on sandy loam soils of Haryana (India). The use of organic manures along with fertilizers and bio-fertilizers resulted in improved nutrient status of soil enhancing both micro and macro nutrient pools in soil. The combination of fertilizers with organic manures reduced the soil pH up to greater extent over sole application of inorganic fertilizers under salt stress conditions. The INM reduced the bulk density, increased the water holding capacity and improved the overall soil health. This resulted in increased transformation of micro and macro nutrients in soil, thus enhancing their uptake by plants giving higher crop production.
Evaluation of bio-pesticides for the management of shoot and fruit borer Leucinodes orbonalis Guenee in brinjal vegetable
The On-farm field study were conducted in farmers field by Krishi Vigyan Kendra at Ramanathapuram village of Senthamangalam block, Namakkal districts to evaluate the bio-pesticides against brinjal shoot and fruit borer (BSFB) under field condition during rabi season 2020. In the treatment T2, seed treatment with Trichoderma viride (4g/kg) and Pseudomonas @ 10g/kg of seed; nursery + seedling dip treatment with Pseudomonas @ 10 g/ litre of water; soil application with neem cake @ 250 kg/ha; Maize as boarder crop against movement of whiteflies; installation of yellow sticky traps @ 20 numbers per hectare; sex pheromone traps @ 20 number per hectare and application of Neem oil formulations 10000 ppm @ one per cent were applied thrice at fifteen days interval starting from peak flowering stage significantly recorded lowest mean shoot infestation (5.78 per cent) of brinjal followed by T1 (6.39 per cent) and over control T3 (14.6 per cent), whereas fruit borer infestation recorded lowest in T2 (8.44%) followed by T1 (10.5 %) and over control T3 (20.9 %) . Maximum fruit yield was recorded in treatment T2 (236.2 q/ha.) was found to be superior over T1 (208.4 q/ha.) and T3 (175.6q./ha.), respectively. Wherein the lowest damaged fruit yield was recorded in T2 (23.6 q./ha) was superior than T1 (28.2 q./ha.) and T3 (32.8 q./ha.), respectively. With respect to gross and net income, T2 recorded highest income (Rs.354300 & Rs.249949) than T1 (Rs.312600 & Rs.201034) and T3 (Rs.263400 & Rs.157749) treatments. The benefit cost ratio of T2 (3.26) is superior over T1 (2.80) and T3 (2.49) treatments respectively.
Impact of Natural Farming Practices on Pea (Pisum sativum L.) in Mid-hills of North-Western Himalayas
The study revealed that application of 3 t ha⁻¹ Ghanjeevamrit + 5% Jeevamrit at 15-day intervals (T2) recorded the highest plant height (79.47 cm), plant biomass (21.60 g/plant), protein content (23.69%), and ascorbic acid content (14.13 mg/100 g). This treatment also improved soil properties with maximum nitrogen (329.27 kg ha⁻¹), phosphorus (37.33 kg ha⁻¹), potassium (378.57 kg ha⁻¹), organic carbon (1.46%) and also emerged as the most cost-effective, achieving the highest yield (99.06 q ha⁻¹), net returns (₹1,77,428.7), and a B:C ratio of 1.48, comparable to 100% RDF (T1). The application of 2 t ha⁻¹ Ghanjeevamrit with 10% Jeevamrit at 15-day intervals is recommended as a sustainable alternative to synthetic fertilizers, enhancing crop productivity, soil health and economic viability in pea cultivation, particularly in hill ecosystems.
Assessment of the Impact on Soil Physico-Chemical and Leaf Properties of Drumstick tree (Moringa oleifera L.) in mid hills of North-Western Himalayas
Plants derive essential resources like water, nitrogen (N) and phosphorus, therefore have an enormous effect on changing the physicochemical properties of soil and leaves. In the current study, we have attempted to find out if Moringa oleifera (drumsticks) which are grown under Nahan, forest division of Himachal Pradesh, had any effect on the physico-chemical characteristics of the soil. Three locations were selected from each one of the four blocks and soil samples were collected under the canopy of Moringa oleifera for evaluation of physicochemical properties. Most of the soil is classified as sandy loam to sandy clay loam. Soil pH was found to be neutral. The EC values were also found to be within the safe limits (<0.8 dS m-1). The soil has been categorized as high organic carbon, P, K, Ca, Mg, SO42-, Cu, Fe and Mn. However, N and Zn content was recorded to be within the medium range. The content of leaf N, P, K, S, Fe, Cu and Mn content was in the high range. Moringa leaves contain an adequate amount of chlorophyll and protein content. Soil EC was important and positively associated with soil P, Ca, Mg, Cu and Mn, whereas organic carbon content of soil is important and positively associated with soil total N, total P, total K, total Ca, total Mg and total Mn. A significant correlation between soil and leaf nutrient content revealed that the soil and leaf analysis used in synchronicity exhibits more reliable information on nutritional status depicting trees with good uptake of nutrients. In addition a comprehensive analysis of their chemical composition, nutritional value and antioxidant potential provided strong dietary recommendations, reinforcing their role as a beneficial component of a balanced diet.
