Enhancing Resource Allocation Strategies for Sustainable Crop Production in the Mid-Hills of Himachal Pradesh
The sustainable production of agricultural crops in the Mid-Hills of Himachal Pradesh requires efficient resource allocation strategies. This study aims to investigate and propose measures to enhance resource allocation strategies for sustainable crop production in the region. A comprehensive study was conducted, utilizing a combination of quantitative analysis and filed surveys. The research focused on understanding the current resource allocaation practices, identifying areas of inefficiency, and exploring potential solutions to enhance sustainability. A multistage random sampling technique was employed to select a sample of farmers involved in crop production. The study revealed that existing resource such as seeds, fertilizers, labor, and irrigation. Furthermore, the study analyzed the relationship between various variables and resource utilization efficiency. Results indicated that variables such as rainfall, land area, literacy index, and crop yield index demonstrated a positive relationship with resource utilization efficiency. Conversely, crop diversification exhibited a negative relationship with efficient resource allocation. Based on the findings, recommendations were formulated to enhance resource allocation strategies for sustainable crop production. These recommendations emphasized the importance of providing farmers with additional technical knowledge and training to optimize resource utilization. By addressing the knowledge gap and promoting access to extension services, farmers can make informed decisions regarding resource allocation, leading to increased production and improved returns on major agricultural crops.
Combining Ability for Moisture Stress in Maize Hybrids
Implementation of moisture stress tolerant maize is one of the way to achieve sustainable production which will secure food for feature generation. On account of that, this study has objective to estimate general combining ability (GCA) and specific combining ability (SCA) of developed hybrids under moisture stress. The study was undertaken at M.P.U.A.T. Udaipur, Rajasthan from 2015‒2017. 45 hybrids were generated from 15 inbred lines with 3 testers and 4 commercial checks utilizing L x T design. These were evaluated in RBD under 3 managed environments with 3 replications each in 2015‒16 rabbi to avoid rainfall in order to estimate the effect of well-watered and moisture stress imposed at different stages on physiological and yield contributing characters of corn. Studies were conducted on only well-watered and managed stress but we developed 3 different environments and tried to make accurate effect of moisture stress on both important stages (i.e. at tasselling and grain filling). That’s why irrigation was regulated at tasselling E2 and grain filling E3 stages which targeted for giving moisture stress for 20 days at starting of both stages while E1 was well-watered. The low significance of GCA and SCA observed revealed the importance of dominant gene action while high GCA / SCA implies both additive and non-additive gene action. Drought stress reduces GY, Chlorophyll content, RWC, LA in both environments E2 and E3 and increases ASI, Proline content, LCT, LDS in E2 when compared with E1.
Effect of the Cold-press Pellet and Mash Feed Forms on the Productive Performance of Laying Hens
The poultry industry is actively seeking effective strategies to optimize feed utilization and improve efficiency. One area of growing interest is the impact of feed particle size and form. Pelleting offers advantages such as reducing ingredient segregation, improving feed flow, and allowing for cost reduction through alternative ingredient incorporation and reduced dietary energy. Cold-press pelleting, which eliminates the need for steam, addresses cost concerns and serves the intended purpose. In this study, the effects of cold-press pellet and mash feed on the production performance of laying hens during their peak laying period were investigated. Ninety-six commercial white leghorn layers were divided into two experimental groups: one fed a mash diet (MD) and the other a pellet diet (PD). Each group consisted of six replicates with eight birds in each replicate. Isocaloric and isonitrogenous diets were provided to all groups, with the mash diet serving as the basis for formulating the cold-press pellet feed. Observations were made on feed intake, feed efficiency, egg production, and egg weight. The results indicate that feed form influenced laying performance, with the pellet diet (PD) outperforming the mash diet (MD) in terms of egg production, average egg weight, feed intake, and feed efficiency. Pellet diets showed positive changes in feed intake, egg weight, and laying rate, ultimately improving production performance. These findings provide support for the advantages of feeding cold-press pellets to commercial laying hens during their peak egg laying period. Overall, incorporating cold-press pellet diets can enhance production performance through improved feed intake, egg weight, and laying rate in commercial egg type chicken.
Mono component cysteine protease enzyme supplementation on protein digestibility in chicken
In vitro crude protein digestibility (IVCPD) followed by in vivo studies were conducted to determine the influence of mono-component cysteine protease enzyme supplementation on digestibility of commonly used vegetable protein sources in layer chicken feed viz., soybean meal, sunflower meal, rapeseed meal and de-oiled groundnut cake. The in vitro crude protein digestibility (IVCPD) was done by two-step (Pepsin- Pancreatin) in vitro assay. In this study, control group had only test ingredients, whereas in treatment groups test ingredients were supplemented with cysteine protease (@ 150 gm/ ton). Cysteine protease supplementation in feed ingredients increased (P<0.05) the IVCPD in sunflower meal (73.38 vs. 67.17 %) and rapeseed meal (70.73 vs 66.03 %). IVCPD of soybean meal and de-oiled groundnut cake was not influenced. Following the in vitro study, an in vivo protein digestibility experiment was conducted in commercial layer cockerels (14 weeks of age). Four dietary treatments were formulated viz., 1) Control diet without enzyme; 2) Control diet plus NSP -ase (@500 g/ ton); 3) Control diet plus cysteine protease @ 150 gm/ ton); 4) Control diet plus both NSP -ase and cysteine protease enzyme. Sixteen cockerels were used in the metabolic trial with 4 birds in each dietary treatment. There was no significant difference in dry matter and crude protein digestibility due to cysteine protease and NSP -ase supplementation. However, the crude protein digestibility increased non- significantly to the tune of 2.11 and 5.11 % as compared to control group when cysteine protease alone or cysteine protease plus NSP-ase, respectively From this study, it can be concluded that cysteine protease enzyme supplementation increases protein digestibility in chicken.
Microbial Isolates as an growth promoting agents for Guava
To evaluate the effect of plant growth promoting microbial strains were tested under in vitro condition. The microorganisms work by multiple mechanisms, such as nitrogen fixation, phosphate solubilization, zinc solubilization, IAA production and siderophore biosynthesis etc. are responsible for the plant growth promotion and increased yield. These microbial isolates in production of phytohormone i.e., IAA and Phosphorus solubilization the strain Bacillus megaterium was found superior, which was followed by Pseudomonas striata and Trichoderma viride. Higher production of siderophore by the strain Pseudomonas fluorescens which was followed by Pseudomonas striata. Higher zinc solubilization observed with Pseudomonas striata followed by Bacillus megaterium and Trichoderma viride. In field conditions when guava plant or row treated with RDF+ Pseudomonas striata showed significant superiority in terms of number of fruits per plant, average fruit weight, yield and improved quality which was followed by RDF+ Trichoderma viride and RDF + Bacillus megaterium.
