Title:

Effects of six plant extracts on rice weevil sitophilus oryzae l. in the stored wheat grains

Author (s): A.U.R. Saljoqi, Munir Khan Afridi, Shah Alam Khan and Sadur-Rehman
Abstract:

Ethanol extracts of six plants materials i.e. bakain drupes (Melia azdarach), habulas leaves (Myrtus communis), mint leaves (Mentha longifolia), bakain leaves, harmal shoots and seeds (Pegnum harmala) and lemon grass roots (Cymbopogon citrates)  against rice weevil, Sitophilus oryzae L. were tested to determine their insecticidal properties. The results revealed that all of the tested materials with some variations had repellent and lethal effects against the pest as compared with the untreated check. Considering the % mortality of the insect as a main index, bakain drupes proved to be the most effective of these six plant materials, showed 61.2 % mortality, followed by habulas (48.40%), mint (47.40%) and bakain leaves (46.80%), while harmal (16.80%) was found less effective followed by lemon grass (35.20%).

Title:

Author (s):

Naushad Ali Turi, Raziuddin, S. Salim Shah and Sardar Ali

Abstract:

For the estimation of mid-parent and better-parent heterosis in Brassica juncea L. genotypes an experiment was conducted at NWFP Agricultural University, Peshawar during 2004-05 and 2005-06 using 8 x 8 full diallel. All the 56 F1 hybrids and their parents were planted in a randomized complete block design with two replications. Out of 56 hybrids, negative mid-parent and better-parent heterosis were estimated in 15 and 10 hybrids for days to 50% emergence, in 20 and 11 hybrids for days to 50% flowering, in 34 and 49 crosses for days to physiological maturity and in 37 and 34 crosses for plant height, respectively whereas positive heterosis were estimated in 12 and 10 crosses for number of primary branches plant-1. However, significant negative mid-parent and better-parent heterosis were recorded in 5 and 4 hybrids for days to 50% emergence, in 05 and 03 for days to 50% flowering, in 10 and 8 for days to physiological maturity, in 7 and 36 for plant height while significantly positive heterosis was recorded in 27 and 4 crosses for number of primary branches plant-1 respectively. Better-parent heterosis reduced to 27% for emergence, 3.85% for flowering, 4.08% for maturity and 22.63% for plant height whereas it reached to 44% for branches plant-1. Among parents, NUM103, NUM113, NUM123 and NUM117 proved to be superior when used as parents in most of the hybrid combinations. Hybrids NUM9xNUM113, NUM103xNUM113, NUM123xNUM117, NUM123x NUM113 and NUM123xNUM124 were best for different characters and their further utilization in breeding programs is suggested.

Title:

Sero-surveillance of Hemorrhagic septicemia in cattle and buffaloes in district Malakand, NWFP

Author (s):

Asadullah Khan, Umar Saddique, Riaz Ahmad, Hamayun Khan, Younas Mohammad and Mohammad Zubair

Abstract:

The present study showed the Sero-surveillance of Hemorrhagic septicemia in cattle and buffaloes in district Malakand, NWFP, Pakistan. The average geometric mean titre (GMT) was recorded against hemorrhagic septicemia in buffaloes in the range of 4.12 to 46.98, while those in cattle were recorded in the range of 4.45 to 46.40. In young buffalo calves, incidence rate, mortality rate and morbidity rate was observed as 22.25%, 21.19% and 95.25%, respectively. In adult buffaloes, morbidity, mortality and case fatality rates were 5.49%, 1.65% and 30%, respectively. In case of young cattle calves, morbidity, mortality and case fatality rates were recorded as 3.94%, 1.77% and 45%, respectively. While in case of adult cattle, morbidity, mortality and case fatality rates were recorded as 2.51%, 0.39% and 15.79%, respectively. During present investigation the incidence rate, mortality and case fatality due to Hemorrhagic septicemia was found greater in the young calves as compared to the adult in both buffaloes and cattle.

Title:

Effects of short term credit advanced by ZTBL for enhancement of crop productivity and income of growers

Author (s):

Mohammad Fayaz, Dawood Jan, Abbas Ullah Jan and Badshah Hussain

Abstract:

The present study was conducted to examine the utilization and effects of short-term credit from Zarai Taraqiati Bank Ltd. (ZTBL) at tehsil Kabal area of district Swat in August 2003. Eighty respondents were selected in which forty were the beneficiaries of ZTBL and the remaining forty were the non-beneficiaries selected from the same area. Paired sample t-test was used to compare the production and income of the beneficiaries without credit and with credit. Independent sample t-test was used to compare the production and income of beneficiaries with non-beneficiaries. On overall basis beneficiariesí farmer utilized 78.84% of the amount of credit for the purpose it was received. While the remaining amount i.e. 21.15% was miss-utilized. Per acre production of beneficiaries with credit for tomato, wheat, maize and onion were 170.4 maunds (1 maund equal to 50kg), 24.6 maunds, 39.4 maunds and 152.4 maunds, respectively. In case of beneficiaries without credit it was 139.6 maunds, 18.93 maunds, 30.3 maunds and 130.7 maunds, respectively on per acre basis. While in case of non-beneficiaries it was 144.5 mounds, 19.25 maunds, 32.2 maunds and 135.3 maunds, respectively on per acre basis. Net return of beneficiaries with credit for tomato, wheat, maize and onion was Rs.17410.9, Rs. 3908.67, Rs. 7695.75, and Rs. 16450.5, respectively on per acre basis. While beneficiaries without credit it was Rs. 11863.21, Rs. 2195.54, Rs. 5981.17, and Rs. 10968.9, respectively on per acre basis. In case of non-beneficiaries it was Rs. 13616.85, Rs. 2830.15, Rs. 6600.88, and Rs. 13465, respectively on per acre basis.

Berseem (trifolium alexandrinum l) and Shaftal (t resupinatum l) after various cuts, biomass incorporation at final harvest supplement with nitrogen, impact on the tasseling and silking coincidenceness, days differences from tasseling to silking and grain fill duration of maize

Author (s):

Habib Akbar, Mohammad Tariq Jan, Amanullah Jan, Zahir Shah, Muhammad Idrees

Abstract:

Two years average results indicated that maximum gap of six days were observed from tasseling to silking. After zero, single and two cuts showed coincidenceness for cob silks and tassel pollen, phenological developments. Maximum grain filling of 43 days were recorded from fallow, shaftal after three cuts and berseem without cut as well. Interactive effect of legumes cutting and N affected grain filling duration. Days gaps between tasselings and silking were lessened for maximum grain fill days. Coincidenceness of inflorescences, tasseling and silking has left beneficial impact on later yield components. The conclusions drawn from the entire research were, as Coincidence and less days differences between tasselling and silking increased grain fill duration, fertilized competent ovules in maize. Organic, unpredicted to be mineralized at need stage and inorganic readily usable form, application both are equally essential under uncertainties for phenological coincidenceness.

Title:

Response of wheat to foliar application of nutrients

Author (s):

Muhammad Arif, Muhammad Aslam Chohan, Sajid Ali, Rozina Gul and Sajjad Khan

Abstract:

Foliar application can guarantee the availability of nutrients to crops for obtaining higher yield. To study the response of wheat to foliar application of nutrients, an experiment was conducted at Agricultural Research Farm of NWFP Agricultural University Peshawar during winter 2005-06. The treatments consist of control (water spray), spray at tillering (single spray) and/or spray at jointing (two sprays) and/or spray at boot stage (three sprays). Significant increase was recorded in number of spikes m-2, grains spike-1, thousand grain weight, biological yield and grain yield with foliar application of nutrients. Three foliar applications of nutrients resulted in maximum number of spikes m-2, grains spike-1, thousand grains weight and biological yield. Maximum grain yield was recorded for two foliar sprays which was statistically similar to that of three foliar sprays. It was concluded that three foliar sprays of nutrient solution at tillering, jointing and boot stages along with half of the recommended doses of N and P helped in enhancing yield and yield components of wheat.
